NLE High-Risk Pregnancy & Obstetric Complications — Hypertensive & Metabolic Disorders of PregnancyExam Answer Templates

Examiner tip

This is a pure recall question. The examiner wants three data points in one sentence: the BP value, the gestational age, and the absence of proteinuria. Missing any one of these will lose the mark.

Model answer

Gestational hypertension is a blood pressure of 140/90 mmHg or higher occurring after 20 weeks of gestation, without proteinuria, and resolving after delivery.

Answer structure

• Line 1: State the BP threshold (≥140/90 mmHg), the gestational age threshold (after 20 weeks), the absence of proteinuria, and resolution postpartum — all in one complete sentence [1 mark]

Scoring breakdown

Common mark deductions

• Writing BP ≥130/80 mmHg instead of ≥140/90 mmHg — wrong threshold earns zero
• Omitting 'without proteinuria' — this is the key distinguishing feature from preeclampsia
• Not specifying 'after 20 weeks' — timing is essential to the definition

Key phrases to include

• BP ≥140/90 mmHg
• after 20 weeks gestation
• without proteinuria
• resolves postpartum

Examiner tip

The NLE frequently tests this exact fact. Memorize: Calcium Gluconate — 1 gram — 10 mL of 10% — IV — 3 minutes. This is a high-alert antidote and the Board expects exact recall.

Model answer

The antidote for magnesium sulfate toxicity is calcium gluconate 1 g (10 mL of a 10% solution) given intravenously over approximately 3 minutes.

Answer structure

• Line 1: Name the drug (calcium gluconate), the dose (1 g / 10 mL of 10% solution), and the route and rate (IV over ~3 minutes) [1 mark]

Scoring breakdown

Common mark deductions

• Writing 'calcium chloride' instead of 'calcium gluconate' — wrong drug, zero marks
• Stating the dose without the concentration (e.g., 'give calcium' alone is insufficient)
• Omitting the IV route

Key phrases to include

• calcium gluconate
• 1 g
• 10 mL of 10% solution
• intravenously
• over 3 minutes

Examiner tip

The sequence of magnesium toxicity signs is a classic NLE question. Always state DTR loss first. The Board loves to use distractors like 'drowsiness' or 'hypotension' — these appear later. Only absent DTRs is the earliest.

Model answer

The earliest sign of magnesium sulfate toxicity is loss of deep tendon reflexes (DTRs), specifically the patellar (knee-jerk) reflex, which occurs when serum magnesium levels rise to approximately 8–10 mEq/L. The appropriate nursing action is to immediately hold (discontinue) the magnesium sulfate infusion and notify the physician.

Answer structure

• Line 1: Identify the earliest sign — loss of deep tendon reflexes (patellar reflex) — with the serum level at which it occurs [1 mark]
• Line 2: State the nursing action — hold the infusion immediately and notify the physician [1 mark]

Scoring breakdown

Common mark deductions

• Stating 'respiratory depression' as the earliest sign — this is the second sign, not the first
• Writing 'slow down the infusion' instead of 'stop/hold' — incomplete action loses the mark
• Forgetting to mention notifying the physician

Key phrases to include

• loss of deep tendon reflexes
• patellar reflex
• earliest sign
• hold the infusion
• 8–10 mEq/L

Examiner tip

The key differentiating word is SEIZURES. If you write 'preeclampsia + seizures = eclampsia' as a formula at the end of your answer, it summarizes the differentiation perfectly and shows clear understanding.

Model answer

Preeclampsia is defined as blood pressure ≥140/90 mmHg occurring after 20 weeks of gestation accompanied by proteinuria or evidence of end-organ damage (such as thrombocytopenia, impaired liver or renal function, pulmonary edema, or cerebral/visual symptoms). Eclampsia is preeclampsia that has progressed to include tonic-clonic seizures that are not attributable to another neurological cause. In summary, eclampsia equals preeclampsia plus seizures.

Answer structure

• Line 1: Define preeclampsia — BP ≥140/90 after 20 weeks + proteinuria or end-organ involvement [1 mark]
• Line 2: Define eclampsia — preeclampsia PLUS tonic-clonic seizures not caused by another condition; note it is a progression of preeclampsia [1 mark]

Scoring breakdown

Common mark deductions

• Saying eclampsia is 'severe preeclampsia' without mentioning seizures — incomplete differentiation
• Omitting the BP value or gestational age from the preeclampsia definition
• Using 'convulsions' alone without specifying tonic-clonic type

Key phrases to include

• BP ≥140/90 mmHg
• after 20 weeks
• proteinuria
• end-organ damage
• tonic-clonic seizures
• not attributable to another cause

Examiner tip

This is one of the most tested nursing actions for magnesium sulfate. Memorize the triad: DTRs + RR + UO. Always pair each parameter with its safe threshold and the action if the threshold is not met. This pattern earns full marks every time.

Model answer

Before administering each dose of magnesium sulfate, the nurse must assess: (1) Deep tendon reflexes (DTRs) — specifically the patellar reflex, which must be present; absent DTRs indicate toxicity and the drug must be held. (2) Respiratory rate — must be at least 12 breaths per minute; a rate below 12/min indicates respiratory depression and the infusion must be withheld. (3) Urine output — must be at least 30 mL per hour; magnesium is renally excreted, so oliguria causes drug accumulation and toxicity.

Answer structure

• Point 1: DTRs — must be present (patellar reflex); rationale: absent DTRs = toxicity [1 mark]
• Point 2: Respiratory rate — must be ≥12 breaths/min; rationale: RR <12 = respiratory depression [1 mark]
• Point 3: Urine output — must be ≥30 mL/hr; rationale: renal clearance of magnesium [1 mark]

Scoring breakdown

Common mark deductions

• Listing 'blood pressure' instead of one of the three core parameters — BP monitoring is important but it is not part of the classic trio
• Stating thresholds incorrectly, e.g., urine output >10 mL/hr or RR >8/min
• Listing the parameters without the threshold values — values are what earn the marks

Key phrases to include

• deep tendon reflexes (DTRs)
• patellar reflex
• respiratory rate ≥12/min
• urine output ≥30 mL/hr
• hold the infusion
• renally excreted

Examiner tip

For HELLP, the NLE always tests whether you know that LP means Low Platelets (not protein). The nursing action that is most unique and commonly tested is 'do NOT palpate the liver' — this is a high-alert safety action that examiners specifically reward.

Model answer

HELLP syndrome is a severe complication of preeclampsia characterized by: H — Hemolysis (destruction of red blood cells), EL — Elevated Liver enzymes (indicating hepatic involvement), and LP — Low Platelets (thrombocytopenia, raising the risk of bleeding and DIC). Two priority nursing considerations are: (1) Avoid palpating the liver — hepatic capsule distension from hemorrhage makes palpation a rupture risk, which would be immediately life-threatening. (2) Monitor closely for signs of bleeding and DIC — low platelets impair clotting; assess for petechiae, ecchymosis, bleeding from IV sites, and changes in coagulation studies.

Answer structure

• Part 1: Expand each letter of the acronym with clinical meaning — H, EL, LP [1 mark]
• Part 2: Priority nursing consideration 1 — avoid liver palpation with rationale [1 mark]
• Part 3: Priority nursing consideration 2 — monitor for bleeding/DIC with rationale [1 mark]

Scoring breakdown

Common mark deductions

• Writing 'Low Protein' instead of 'Low Platelets' for LP — a critical factual error
• Stating nursing actions without rationale — in 3-mark questions, rationale is expected
• Omitting the connection between low platelets and bleeding/DIC risk

Key phrases to include

• Hemolysis
• Elevated Liver enzymes
• Low Platelets
• thrombocytopenia
• avoid liver palpation
• rupture risk
• DIC
• coagulation

Examiner tip

Start with the BP number — it is the anchor of this answer. Then systematically work through organ systems: brain (headache, vision), liver (epigastric/RUQ pain), kidneys (oliguria), and blood (platelets). This organ-system approach ensures you never miss a severe feature.

Model answer

Preeclampsia is classified as having severe features when any of the following are present: (1) Blood pressure ≥160/110 mmHg on two readings taken 6 hours apart. (2) Severe, persistent headache unresponsive to medication, indicating cerebral involvement. (3) Visual disturbances such as blurring of vision, scotomata (blind spots), or photophobia. (4) Epigastric or right-upper-quadrant pain indicating hepatic involvement. Additional severe features include hyperreflexia with clonus, oliguria (less than 500 mL in 24 hours), pulmonary edema, and thrombocytopenia.

Answer structure

• Opening: State BP threshold that defines severe features — ≥160/110 mmHg [1 mark]
• Middle: List at least three neurological or hepatic indicators — headache, visual disturbances, epigastric/RUQ pain [1 mark]
• Closing: Include additional organ-system indicators — hyperreflexia/clonus, oliguria, pulmonary edema [1 mark]

Scoring breakdown

Common mark deductions

• Writing ≥140/90 as the threshold for severe features — this is for non-severe preeclampsia
• Listing fewer than three indicators when the question asks for four
• Confusing symptoms (e.g., 'ankle edema') which is normal in pregnancy and not a severe feature

Key phrases to include

• BP ≥160/110 mmHg
• severe persistent headache
• visual disturbances
• scotomata
• epigastric pain
• right-upper-quadrant pain
• hyperreflexia
• clonus
• oliguria
• pulmonary edema

Examiner tip

Case studies require you to (1) interpret the data, (2) state the priority action, and (3) implement the specific intervention with exact details. Examiners penalize vague actions like 'give the antidote' without naming the drug and dose. In the NLE, incomplete drug information is treated as an incomplete answer.

Model answer

The assessment findings indicate magnesium sulfate toxicity (respiratory rate of 10/min is below the safe threshold of 12/min, and absent patellar reflex indicates the drug level has risen above the therapeutic range). The priority nursing actions are: (1) Immediately stop (hold) the magnesium sulfate infusion. (2) Administer the antidote — calcium gluconate 1 g (10 mL of a 10% solution) intravenously, given slowly over approximately 3 minutes. (3) Administer supplemental oxygen and notify the physician immediately; prepare for continuous respiratory monitoring and possible respiratory support.

Answer structure

• Step 1: Identify the problem — state that findings indicate magnesium toxicity [1 mark]
• Step 2: Priority action — immediately stop/hold the magnesium sulfate infusion [1 mark]
• Step 3: Administer antidote — calcium gluconate, 1 g IV, 10 mL of 10% solution, over 3 minutes; plus oxygen and physician notification [1 mark]

Scoring breakdown

Common mark deductions

• Slowing the infusion instead of stopping it — an inadequate response to confirmed toxicity
• Administering calcium chloride instead of calcium gluconate
• Failing to provide the dose and route of the antidote
• Not addressing the respiratory concern (oxygen, monitoring)

Key phrases to include

• magnesium sulfate toxicity
• hold/stop the infusion
• calcium gluconate
• 1 g
• 10 mL of 10% solution
• IV over 3 minutes
• supplemental oxygen
• notify physician

Examiner tip

Use a numbered structure for 5-mark long answers. Examiners score point-by-point, so clear headings like 'Airway,' 'Safety,' and 'Post-Seizure' help them award marks quickly. The most common error in this question is advocating restraint — examiners specifically look for 'do NOT restrain' as a differentiating statement.

Model answer

An eclamptic seizure is a life-threatening emergency requiring immediate, structured nursing intervention. Management is organized as follows:

1. AIRWAY (Priority One — Maslow's Physiological Need): Turn the client immediately to the left lateral (side-lying) position. This prevents aspiration of secretions and maintains airway patency. Do NOT place anything in the client's mouth — no tongue blades, no fingers — as this risks injury and does not prevent tongue-biting effectively.
2. SAFETY: Do NOT restrain the client during the seizure. Protect her from injury by padding the side rails and removing hazardous objects from the immediate environment. Remain at the bedside throughout the seizure episode.
3. OXYGENATION: Administer supplemental oxygen via face mask (8–10 L/min) during and after the seizure to correct hypoxia caused by apnea during the tonic-clonic phase.
4. POST-SEIZURE CARE: After the seizure ends, suction oral secretions to maintain airway patency. Assess level of consciousness, vital signs, and fetal heart rate. Document the duration, character, and sequence of the seizure.
5. PHARMACOLOGICAL AND DEFINITIVE MANAGEMENT: Administer magnesium sulfate as ordered to prevent recurrent seizures (loading dose: 4–6 g IV over 15–30 minutes, maintenance: 1–2 g/hr). Notify the physician and prepare the client for delivery, because delivery of the fetus and placenta is the only definitive cure for eclampsia. Monitor BP and administer antihypertensives (hydralazine, labetalol) as prescribed for BP ≥160/110 mmHg.

Answer structure

• Point 1: Airway — left lateral position, nothing in the mouth, rationale for aspiration prevention [1 mark]
• Point 2: Safety — do not restrain, pad rails, remain at bedside [1 mark]
• Point 3: Oxygenation — administer supplemental oxygen, address hypoxia [1 mark]
• Point 4: Post-seizure — suction secretions, assess neuro status and FHR, document [1 mark]
• Point 5: Pharmacological and definitive — magnesium sulfate with dose, antihypertensives, prepare for delivery as the only cure [1 mark]

Scoring breakdown

Common mark deductions

• Writing 'restrain the client to prevent injury' — this is WRONG and will lose marks; restraint during a seizure causes musculoskeletal injury
• Omitting the fetal assessment post-seizure — every obstetric emergency requires fetal monitoring
• Failing to mention delivery as the definitive cure — this is the most important long-term action
• Giving magnesium dose without loading and maintenance distinction
• Starting with drug administration before airway — incorrect priority order loses structure marks

Key phrases to include

• left lateral position
• do not restrain
• nothing in the mouth
• supplemental oxygen
• suction secretions
• fetal heart rate
• magnesium sulfate
• 4–6 g IV
• delivery is the only cure
• padded side rails

Structure GDM answers in a checklist format: Screen → Risks (maternal then fetal) → Manage → Teach. The Board loves testing why neonatal hypoglycemia occurs — always explain the fetal hyperinsulinemia mechanism, not just name the complication. This shows clinical reasoning, not just memorization.

Model answer

Gestational Diabetes Mellitus (GDM) is glucose intolerance first recognized during pregnancy, caused by insulin resistance from placental hormones (human placental lactogen, progesterone, and cortisol).

1. DIAGNOSIS: Screening is performed with the 50-g oral glucose challenge test (GCT) at 24–28 weeks of gestation. A 1-hour glucose level ≥140 mg/dL requires a confirmatory 3-hour, 100-g oral glucose tolerance test (OGTT). Glycemic targets during pregnancy are: fasting <95 mg/dL, 1-hour postprandial <140 mg/dL, 2-hour postprandial <120 mg/dL.
2. MATERNAL RISKS: Preeclampsia, polyhydramnios, urinary tract and candidal infections, and an increased cesarean delivery rate.
3. FETAL/NEONATAL RISKS: Macrosomia (birth weight >4,000 g) leading to shoulder dystocia during delivery; neonatal hypoglycemia (due to fetal hyperinsulinemia that continues after the maternal glucose supply is cut at birth); respiratory distress syndrome (insulin delays surfactant maturation); hyperbilirubinemia; and congenital anomalies (with pre-existing, poorly controlled diabetes).
4. MANAGEMENT: The cornerstone of GDM management is Medical Nutrition Therapy (MNT) — a carbohydrate-controlled diet — combined with regular physical activity. When diet and exercise fail to achieve glycemic targets, insulin therapy is initiated. Insulin is the preferred agent because it does not cross the placenta and is the safest for the fetus. Oral agents (metformin, glyburide) may be used in some cases, but insulin remains the gold standard.
5. NURSING RESPONSIBILITIES: Teach the client self blood-glucose monitoring technique and recording. Educate on insulin administration, correct technique, and safe storage. Teach recognition of hypoglycemia (shakiness, sweating, confusion) and hyperglycemia (polyuria, polydipsia, blurred vision). After delivery, monitor the newborn for hypoglycemia and initiate early feeding. Advise the mother that GDM usually resolves postpartum, but she has an elevated lifetime risk for type 2 diabetes — schedule a postpartum OGTT at 6–12 weeks.

Answer structure

• Part 1: Pathophysiology (brief) and diagnostic screening criteria — 50-g GCT at 24–28 weeks, threshold ≥140 mg/dL, glycemic targets [1 mark]
• Part 2: Maternal risks — at least three: preeclampsia, polyhydramnios, infections, cesarean rate [1 mark]
• Part 3: Fetal/neonatal risks — macrosomia, neonatal hypoglycemia, RDS, hyperbilirubinemia [1 mark]
• Part 4: Management — MNT first, then insulin (rationale: does not cross placenta); mention oral agents [1 mark]
• Part 5: Nursing responsibilities — SBGM teaching, insulin education, newborn monitoring, postpartum follow-up [1 mark]

Scoring breakdown

Common mark deductions

• Stating the GCT is done at 20 weeks — wrong timing; it is 24–28 weeks
• Giving the screening threshold as ≥130 mg/dL instead of ≥140 mg/dL
• Omitting the explanation for neonatal hypoglycemia — the mechanism (fetal hyperinsulinemia) earns the mark
• Not specifying why insulin is preferred over oral agents (must state 'does not cross the placenta')

Key phrases to include

• 50-g glucose challenge test
• 24–28 weeks
• ≥140 mg/dL
• 3-hour 100-g OGTT
• fasting <95 mg/dL
• macrosomia
• neonatal hypoglycemia
• fetal hyperinsulinemia
• insulin does not cross the placenta
• Medical Nutrition Therapy
• self blood-glucose monitoring
• postpartum OGTT

Examiner tip

The NLE loves to test ACE inhibitor contraindication in pregnancy. Always name the drug class AND give the reason (fetal renal damage/teratogenic). Saying 'it is harmful' without a mechanism does not earn the rationale mark.

Model answer

Antihypertensive medications used for severe hypertension in pregnancy (BP ≥160/110 mmHg) include: (1) Hydralazine — given IV at 5–10 mg; monitor for maternal hypotension and reflex tachycardia. (2) Labetalol — given IV at an initial dose of 20 mg; avoid in clients with asthma, heart failure, or bradycardia. (3) Nifedipine — given orally; monitor for hypotension. Methyldopa is also used for chronic hypertension management. A drug class that must be avoided in pregnancy is ACE inhibitors (such as captopril or enalapril) and Angiotensin Receptor Blockers (ARBs). These are teratogenic and cause fetal renal damage, oligohydramnios, and fetal growth restriction.

Answer structure

• Part 1: Three approved antihypertensives — hydralazine, labetalol, nifedipine (or methyldopa) [1 mark]
• Part 2: Drug to avoid — ACE inhibitors and/or ARBs, correctly named [1 mark]
• Part 3: Reason for avoidance — teratogenic; causes fetal renal damage, oligohydramnios [1 mark]

Scoring breakdown

Common mark deductions

• Naming only two drugs when three are asked for
• Identifying diuretics as the drug to avoid — while used cautiously, ACE inhibitors/ARBs are the critical teratogens being tested here
• Saying 'harmful to the baby' without specifying the mechanism of teratogenicity

Key phrases to include

• hydralazine
• labetalol
• nifedipine
• methyldopa
• ACE inhibitors
• ARBs
• teratogenic
• fetal renal damage
• oligohydramnios

Examiner tip

The word 'hyperemesis' literally means excessive vomiting — but the exam tests whether you know the consequences: weight loss >5%, ketonuria, and metabolic alkalosis. These three words together form the complete answer and will earn both marks.

Model answer

Hyperemesis gravidarum is a severe, persistent form of nausea and vomiting in pregnancy that goes beyond ordinary morning sickness. It is characterized by: (1) Weight loss of more than 5% of pre-pregnancy body weight due to inability to retain food or fluids. (2) Dehydration with electrolyte imbalances — specifically hypokalemia and metabolic alkalosis from loss of gastric hydrochloric acid, and ketonuria from starvation ketosis. (3) Significant functional impairment requiring hospitalization for IV fluid replacement and antiemetic therapy. It is associated with elevated levels of human chorionic gonadotropin (hCG) and is more common in molar pregnancy and multiple gestation.

Answer structure

• Line 1: Definition — severe persistent vomiting beyond morning sickness, causing dehydration and weight loss >5% [1 mark]
• Line 2: Three distinguishing features — weight loss >5%, ketonuria, electrolyte imbalance (hypokalemia, metabolic alkalosis) requiring hospitalization [1 mark]

Scoring breakdown

Common mark deductions

• Describing hyperemesis gravidarum the same as normal morning sickness without identifying severity markers
• Omitting ketonuria — this is a key laboratory differentiator that examiners specifically look for
• Not specifying the electrolyte imbalance type (hypokalemia and metabolic alkalosis)

Key phrases to include

• severe persistent nausea and vomiting
• weight loss more than 5%
• dehydration
• ketonuria
• hypokalemia
• metabolic alkalosis
• hCG

Examiner tip

The Board expects you to know the treatment ladder: Pyridoxine (B6) ± doxylamine FIRST, then escalate to metoclopramide, promethazine, and ondansetron. Starting with ondansetron on an exam answer indicates you skipped the first-line option and will lose the mark.

Model answer

The first-line antiemetic treatment for hyperemesis gravidarum is pyridoxine (Vitamin B6), often combined with doxylamine, taken orally. Pyridoxine is a water-soluble B vitamin that reduces nausea through its role in neurotransmitter metabolism; it is considered safe in pregnancy and is the recommended first-line pharmacological option before escalating to stronger antiemetics such as metoclopramide, promethazine, or ondansetron.

Answer structure

• Line 1: Name the drug — pyridoxine (Vitamin B6) — with or without doxylamine; state it is given orally and is first-line [1 mark]

Scoring breakdown

Common mark deductions

• Writing 'ondansetron' as the first-line drug — it is a later step in the treatment ladder, not first-line
• Writing 'promethazine' as first-line — also a second- or third-line option
• Not naming pyridoxine as Vitamin B6 — using only the brand name without the generic

Key phrases to include

• pyridoxine
• Vitamin B6
• doxylamine
• first-line
• safe in pregnancy
• oral

Examiner tip

Five-mark case studies are scored against a marking rubric with five distinct criteria. Use numbered paragraphs with bold subheadings so the examiner can clearly match your content to each criterion. Include a NANDA nursing diagnosis — this differentiates a nursing care plan from a medical care plan and examiners reward it. Always end with 'delivery is the only cure' — it signals you understand the definitive management principle.

Model answer

This client presents with preeclampsia with severe features (BP ≥160/110 mmHg, severe headache, and significant proteinuria). The nursing management plan is as follows:

1. IMMEDIATE SAFETY AND SEIZURE PRECAUTIONS (Priority — Airway/Safety per Maslow): Place the client in a quiet, dimly lit private room to minimize sensory stimulation that could precipitate a seizure. Raise and pad the side rails. Place suction equipment, oxygen, and an emergency airway kit at the bedside. Ensure call light is within reach. Nursing Diagnosis: Risk for Injury (seizure) related to cerebral irritability secondary to preeclampsia with severe features.
2. POSITIONING AND PERFUSION: Position the client in the left lateral recumbent position to maximize uteroplacental perfusion and reduce aortocaval compression. Apply continuous fetal heart rate (FHR) monitoring.
3. MAGNESIUM SULFATE ADMINISTRATION: Administer magnesium sulfate as ordered: Loading dose — 4–6 g IV over 15–30 minutes via infusion pump. Maintenance — 1–2 g per hour continuous IV infusion. Before starting and every hour during infusion, assess: (a) Deep tendon reflexes — must be present; (b) Respiratory rate — must be ≥12/min; (c) Urine output — must be ≥30 mL/hr. Keep calcium gluconate 1 g (10 mL of 10% solution) at the bedside as the antidote. Insert a urinary catheter for accurate hourly urine measurement.
4. ANTIHYPERTENSIVE THERAPY: Administer prescribed antihypertensives (hydralazine 5–10 mg IV or labetalol 20 mg IV) for BP ≥160/110 mmHg to prevent maternal stroke. Recheck BP 20–30 minutes after each dose. Target BP: 140–150/90–100 mmHg (avoid aggressive lowering to protect uteroplacental perfusion).
5. MONITORING AND DOCUMENTATION: Perform and document neurological assessment (LOC, clonus, headache, visual symptoms) every 1–2 hours. Monitor intake and output strictly. Assess for signs of pulmonary edema (dyspnea, crackles, SpO2 <95%). Prepare the client and family for delivery — delivery is the only definitive cure. Provide emotional support and clear, calm explanations of all procedures per the client's right to information under RA 9173.

Answer structure

• Part 1: Seizure precautions — quiet room, padded rails, suction and O2 at bedside, nursing diagnosis [1 mark]
• Part 2: Positioning — left lateral; continuous FHR monitoring [1 mark]
• Part 3: Magnesium sulfate — loading and maintenance dose, three pre-infusion assessments, calcium gluconate at bedside, Foley catheter [1 mark]
• Part 4: Antihypertensive therapy — drug name, dose, timing, target BP rationale [1 mark]
• Part 5: Ongoing monitoring — neuro assessment, I&O, pulmonary edema watch, prepare for delivery, patient education and rights [1 mark]

Scoring breakdown

Common mark deductions

• Not including the NANDA nursing diagnosis when the question involves clinical management
• Giving magnesium doses without separating the loading dose from maintenance
• Omitting calcium gluconate at the bedside — this is a safety standard that examiners mark specifically
• Using wrong antihypertensives (e.g., ACE inhibitors) — this is an automatic mark deduction
• Not mentioning delivery as the definitive cure in a case with severe features

Key phrases to include

• preeclampsia with severe features
• quiet dimly lit room
• padded side rails
• left lateral position
• continuous FHR monitoring
• 4–6 g IV loading dose
• 1–2 g/hr maintenance
• DTRs, RR ≥12/min, UO ≥30 mL/hr
• calcium gluconate at bedside
• hydralazine or labetalol
• delivery is the definitive cure
• Risk for Injury

Examiner tip

This question requires number-specific recall. The Board expects: 4–7 = therapeutic, 8–10 = DTR loss (HOLD), 10–12 = respiratory depression (ANTIDOTE). Memorize these three ranges — they are tested almost every NLE cycle in different question formats.

Model answer

The therapeutic serum level of magnesium sulfate is 4–7 mEq/L (approximately 4.8–8.4 mg/dL). Signs of toxicity appear in a sequential manner as the level rises beyond the therapeutic range: Loss of deep tendon reflexes (DTRs) occurs at approximately 8–10 mEq/L — this is the earliest sign and indicates the infusion must be held. Respiratory depression (respiratory rate below 12 breaths per minute) occurs at approximately 10–12 mEq/L. Respiratory and cardiac arrest occurs at very high levels (greater than 15 mEq/L). Urine output below 30 mL/hr is also monitored as oliguria causes drug accumulation and accelerates toxicity.

Answer structure

• Line 1: State therapeutic level — 4–7 mEq/L [1 mark]
• Line 2: Sequential toxicity levels — DTR loss at 8–10 mEq/L, respiratory depression at 10–12 mEq/L, cardiac arrest >15 mEq/L [1 mark]

Scoring breakdown

Common mark deductions

• Writing the therapeutic level as 2–4 mEq/L or 6–8 mEq/L — incorrect range
• Reversing the order (stating respiratory depression before DTR loss)
• Omitting the approximate serum levels at which each sign occurs

Key phrases to include

• 4–7 mEq/L
• therapeutic level
• loss of DTRs
• 8–10 mEq/L
• respiratory depression
• 10–12 mEq/L
• cardiac arrest
• >15 mEq/L

Do

• Write the complete fact in one sentence: drug name + dose + route + rationale if space allows
• Use exact numbers: '≥140/90 mmHg,' '4–7 mEq/L,' '1 g IV over 3 minutes'
• Use correct generic drug names (e.g., 'calcium gluconate,' not just 'calcium')
• Circle or underline the key fact if your handwriting may be unclear

Don't

• Do not write more than 2 lines — examiners do not give bonus marks for extra writing on 1-mark items
• Do not hedge: avoid 'I think' or 'possibly' — state the fact with confidence
• Do not confuse similar drugs (calcium gluconate vs. calcium chloride)
• Do not skip over 1-mark questions — they add up to the passing margin

Do

• Number your points: (1) and (2) to make scoring clear for the examiner
• Pair each fact with its clinical significance: 'Loss of DTRs [fact] indicates magnesium toxicity and the infusion must be held [action/rationale]'
• Use contrasting language for differentiation questions: 'In contrast to...' or 'Unlike...'
• Include the threshold value when discussing clinical parameters (e.g., 'RR <12/min')

Don't

• Do not write one long paragraph — two separate points are easier to score
• Do not state an action without a rationale in clinical questions
• Do not confuse the two concepts being differentiated (e.g., preeclampsia vs. eclampsia)

Do

• Use a structured format: (1), (2), (3) — one mark per number
• Add a one-line rationale to each nursing action to demonstrate clinical reasoning
• Use the correct NANDA format for nursing diagnosis questions: problem + related to + as evidenced by
• For drug questions: name + dose + route + monitoring = complete answer

Don't

• Do not write only two points and expect full marks — three separate scorable points are required
• Do not repeat the same idea in different words to fill space
• Do not omit the rationale on nursing action questions — 3-mark questions almost always require 'because' or 'to prevent'

Do

• Use numbered sections with clear subheadings: '1. AIRWAY,' '2. SAFETY,' '3. PHARMACOLOGICAL MANAGEMENT'
• Apply Maslow's hierarchy to justify your prioritization order — state the priority explicitly
• Include NANDA nursing diagnoses for all clinical management questions
• State exact drug doses, routes, and monitoring thresholds (e.g., '4–6 g IV over 15–30 min')
• End the answer with the definitive management principle (e.g., 'Delivery is the only cure for eclampsia')
• Reference patient rights and the Philippine Nursing Act (RA 9173) for patient education and informed consent components

Don't

• Do not write a single long paragraph — it is nearly impossible for examiners to extract five separate criteria
• Do not omit the rationale for any nursing action — in 5-mark questions, reasoning is as important as the action itself
• Do not use vague language like 'monitor the patient' without specifying what to monitor and what threshold triggers an action
• Do not forget fetal assessment — in obstetric questions, the fetus is always part of the complete answer
• Do not go over 25 lines — focused, precise answers score higher than lengthy, repetitive ones
