Hypertensive & Metabolic Disorders of Pregnancy - Memory Anchors
Memory techniques work because they hijack the brain's natural love for stories, patterns, and vivid images. Your brain remembers a dramatic story about a Filipino nurse far better than a dry list of numbers. In this chapter, every dangerous drug dose, every toxicity sign, and every diagnostic threshold is paired with a creative hook — a mnemonic, an analogy, a mini-story, or a visual image — so that when exam pressure hits, your memory fires automatically. For a high-stakes exam like the NLE administered by the PRC Board of Nursing, that difference is everything. Work through each anchor actively: say it aloud, picture it, and then try the recall trigger without looking. The goal is to make these clinical numbers and sequences as automatic as your own name.
Memory anchors
Preeclampsia definition: BP ≥140/90 after 20 weeks WITH proteinuria
Memory aid
Think of the word PRE-ECLAMPSIA as 'PRE = Proteinuria Required Exactly.' The moment you see PRE, think: 'Pressure + pRotEin.' If there's no protein, it's NOT yet preeclampsia — it's just gestational HTN. Draw a mental gate: blood pressure knocks on the door at 20 weeks, but only ENTERS if it brings its protein ID card.
Why it works
Acronym-based memory creates a retrieval hook on the word itself. Every time you read 'preeclampsia,' the gate image triggers the dual requirement.
Example usage
Exam question: A G2P1 woman at 32 weeks has BP 145/95 but no proteinuria. Which condition does this describe? Your mind fires: PRE needs Protein → No protein = NOT preeclampsia → Answer: Gestational hypertension.
Recall trigger
The word PRE-ECLAMPSIA → 'Pressure + pRotEin'
Severe features of preeclampsia begin at BP ≥160/110 mmHg
Memory aid
Chant this: 'ONE-SIXTY over ONE-TEN — that is when it gets severe, amen!' Picture a Filipino priest slamming his fist on the altar at exactly 160/110, declaring 'SEVERE NA ITO!' The drama of the scene burns the numbers into memory.
Why it works
Rhyme and emotional drama create dual encoding — auditory rhythm plus vivid visual — making the threshold unforgettable.
Example usage
Exam: At what BP does preeclampsia become severe? Hear the chant: 'one-sixty over one-ten' → 160/110 mmHg.
Recall trigger
Think 'the priest' → 160/110 → SEVERE
Severe features mnemonic: Headache, Visual changes, Epigastric pain, Hyperreflexia — plus oliguria, pulmonary edema
Memory aid
Use the mnemonic: 'HAVE PHO' — H: Headache (severe, persistent), A: Altered vision (blurring, scotomata), V: Vomiting or epigastric pain (right-upper-quadrant), E: Edema (pulmonary), P: Platelets low (thrombocytopenia), H: Hyperreflexia with clonus, O: Oliguria (under 500 mL/24h). Picture yourself eating a bowl of PHO noodle soup but every symptom is spilling out of the bowl — it's a terrible, dangerous meal.
Why it works
The food-based acronym is culturally resonant for Filipino students (pho is familiar street food), and the visual of spilling danger out of a bowl creates a vivid image.
Example usage
Exam: Which finding indicates preeclampsia with severe features? Run through HAVE PHO — any feature listed matches a severe criterion.
Recall trigger
Spilling bowl of PHO → HAVE PHO → severe preeclampsia features
HELLP Syndrome: Hemolysis, Elevated Liver enzymes, Low Platelets
Memory aid
Picture a traffic light in a hospital hallway. RED light = blood cells being destroyed (Hemolysis). YELLOW light = liver enzymes rising (like bile, yellow). GREEN light turned OFF = platelets gone (Low Platelets — the green 'go' signal is out). The traffic light is broken and the car (mother and baby) is in danger. Also, remember: the liver is bruised — NEVER palpate it (rupture risk), just like you never push a broken traffic light.
Why it works
Color-coded visual association links each component of HELLP to a color and action, creating an immediate and memorable image.
Example usage
Exam: A pregnant woman has RUQ pain, nausea, and lab results showing low platelets and elevated AST/ALT. What syndrome? See the broken traffic light → HELLP.
Recall trigger
Broken traffic light in the ward → RED-YELLOW-GREEN OFF → H-E-L-L-P
Magnesium sulfate loading dose: 4–6 g IV over 15–30 minutes
Memory aid
Remember the chunk: '4-6 grams, 15-30 minutes.' Group them as DOUBLES: 4 and 6 are even numbers two apart; 15 and 30 — 15 doubled is 30. So your brain stores it as 'two doubles': [4,6] and [15,30]. Mnemonic phrase: 'FOUR to SIX grams, FIFTEEN to THIRTY minutes — load it FAST but not TOO fast.'
Why it works
Chunking reduces cognitive load by organizing numbers into recognizable patterns (doubles), which are far easier to store than isolated digits.
Example usage
Exam: What is the correct loading dose of MgSO4 for eclampsia prevention? Recall DOUBLES → 4-6 g IV over 15-30 min.
Recall trigger
The word 'loading' → think DOUBLES → 4-6 grams, 15-30 minutes
Magnesium sulfate maintenance dose: 1–2 g/hour continuous IV
Memory aid
Chant: 'After the load, slow and steady — ONE to TWO grams hourly, keep mama ready!' Picture a slow drip from an IV bag labeled '1-2' ticking like a clock — one to two every hour, steady as a heartbeat.
Why it works
Rhythmic chanting combined with a visual (the IV clock) creates auditory and visual dual encoding for an easily confused detail.
Example usage
After giving the loading dose, the nurse sets the infusion pump. Recall the chant → 1-2 g/hour maintenance.
Recall trigger
IV bag ticking like a clock → 1-2 g/hour
Magnesium therapeutic serum level: 4–7 mEq/L
Memory aid
Think of magnesium levels as a rice cooker temperature. Below 4 mEq/L = rice undercooked — seizures not prevented (therapeutic failure). Between 4 and 7 mEq/L = perfectly cooked rice — the SAFE ZONE. Above 7 mEq/L = rice burning, cooker about to explode — TOXICITY. Your Filipino lola's rice cooker has a sweet spot; so does MgSO4.
Why it works
The rice cooker is a universally familiar household image in Filipino culture, making an abstract laboratory value concrete and memorable.
Example usage
Exam: What is the therapeutic serum magnesium level? Picture the perfectly cooked rice → 4-7 mEq/L.
Recall trigger
Rice cooker sweet spot → 4-7 mEq/L therapeutic range
Magnesium toxicity signs in order: DTR loss → Respiratory depression → Oliguria → Cardiac arrest
Memory aid
Story: 'Nurse Rey is watching her patient on MgSO4. First, the patient's knee doesn't kick when tapped (DEEP TENDON REFLEXES LOST — earliest sign). Rey holds the infusion and shouts for help. But it's too late — the patient's breathing slows to under 12 per minute (RESPIRATORY DEPRESSION). Then the Foley bag barely has any urine (OLIGURIA, under 30 mL/hr). Finally, the monitor alarms — CARDIAC ARREST.' Nurse Rey knows: NO REFLEXES = STOP THE MAG. She reaches for the calcium gluconate at the bedside.
Why it works
A narrative sequence with a named character (Filipino name) encodes the order of toxicity signs as a story arc, which the brain processes far more easily than a list.
Example usage
Exam: What is the FIRST sign of magnesium toxicity? Recall Nurse Rey's story — the KNEE doesn't kick → Loss of DTRs is the EARLIEST sign.
Recall trigger
Nurse Rey watching the knee → DTR → RR → Urine → Heart
Antidote for magnesium toxicity: Calcium gluconate 1 g (10 mL of 10% solution) IV over 3 minutes
Memory aid
Remember: 'CAL-GLUC at the BED — 1 gram, 10 mL, 3 MIN.' Visualize a yellow syringe labeled 'CAL-GLUC' sitting on the bedside table EVERY time mag is running — it never leaves the bedside. The numbers: 1g, 10mL, 3 min — think '1-10-3' like a countdown: 1... 10... 3 minutes to save a life. Reverse-count: 3-10-1 (3 minutes, 10 mL, 1 gram).
Why it works
The visual of the yellow syringe at the bedside creates a spatial memory cue, and the countdown format encodes the numbers in a narrative sequence.
Example usage
Exam: The patient on MgSO4 has absent DTRs and RR of 10. What is the antidote and dose? See the yellow syringe → Calcium gluconate 1 g (10 mL of 10%) IV over 3 minutes.
Recall trigger
Yellow syringe at bedside → CAL-GLUC → 1g, 10mL, 3 min
MgSO4 monitoring: Check DTRs, RR ≥12/min, UO ≥30 mL/hr BEFORE and DURING infusion
Memory aid
Use the acronym 'DRU' — D: Deep tendon reflexes (present = safe), R: Respiratory rate (≥12/min = safe), U: Urine output (≥30 mL/hr = safe). Picture a Filipino nurse doing a DRU-check before every dose — she 'DROOS' (draws) safety from the patient. If any DRU is abnormal → HOLD the mag and call the doctor. DRU is your safety checklist.
Why it works
A three-letter acronym with a memorable action word ('droo' rhymes with 'drew') makes the three-parameter monitoring checklist instantly recallable under pressure.
Example usage
Before starting the next MgSO4 bag, the nurse performs DRU: DTRs present? RR 14? UO 40 mL/hr? All safe → proceed. One abnormal → HOLD.
Recall trigger
DRU check → DTRs, Respirations, Urine output
Eclamptic seizure priority: Airway, Side position, NO restraints, Nothing in mouth
Memory aid
Story: 'Nurse Ana walks into a room to find her patient convulsing. Her first thought: AIRWAY — she turns the patient to her LEFT SIDE so secretions drain. She does NOT hold the patient down (no restraints — broken bones or aspiration). She does NOT shove anything in her mouth (that old pillow trick is DANGEROUS). She calls for help, provides O2, and watches the clock. After it stops — suction, assess baby, prepare for delivery. DELIVERY IS THE ONLY CURE.' Every action Nurse Ana takes follows the ABCs.
Why it works
The story creates an action sequence with emotional stakes (the convulsing patient), making each correct and incorrect action vivid and memorable.
Example usage
Exam: During an eclamptic seizure, what is the priority nursing action? Recall Nurse Ana → Turn to side, protect airway, do NOT restrain.
Recall trigger
Convulsing patient → Nurse Ana → Turn, don't restrain, nothing in mouth
Preeclampsia position: LEFT LATERAL RECUMBENT; room: quiet and dim
Memory aid
Think of the preeclamptic mom as a sleeping phone that needs charging: you always plug it in on the LEFT side of the bed (left lateral position — maximizes placental blood flow, like a charger giving power to the baby). The room must be in AIRPLANE MODE — quiet and dim (no loud alerts, no bright lights — sensory stimulation can trigger a seizure). Left lateral = charging position; airplane mode = seizure prevention environment.
Why it works
The smartphone analogy is deeply familiar to Filipino students and maps two separate concepts (position and environment) onto one memorable device.
Example usage
Exam: Which position is preferred for a woman with preeclampsia? Charging phone on the LEFT → Left lateral recumbent.
Recall trigger
Phone charging on the left + Airplane mode → Left lateral + Quiet dim room
Antihypertensives safe in pregnancy: Hydralazine, Labetalol, Nifedipine, Methyldopa. AVOID ACE inhibitors and ARBs.
Memory aid
Safe drugs: 'HNLM' → 'Healthy Ninas Love Methyldopa' — H: Hydralazine, N: Nifedipine, L: Labetalol, M: Methyldopa. These are the four friends. The enemies are ACE inhibitors and ARBs — remember 'ACE = Against the Child's Existence' (fetal renal damage, teratogenic). Never give ACE/ARBs to a pregnant woman.
Why it works
A familiar Filipino name (Nina) plus a strong emotional phrase ('Against the Child's Existence') creates dual positive-negative memory cues for the safe vs. contraindicated drugs.
Example usage
Exam: Which antihypertensive is contraindicated in pregnancy? Recall 'ACE = Against Child's Existence' → ACE inhibitors and ARBs are CONTRAINDICATED.
Recall trigger
Healthy Ninas Love Methyldopa → H, N, L, M safe; ACE = Against Child's Existence = AVOID
GDM screening: 50-g glucose challenge at 24–28 weeks; ≥140 mg/dL → proceed to 3-hour 100-g OGTT
Memory aid
Chunk it as a STAIRCASE: Step 1 = 50g drink at 24-28 weeks (first step is lighter — only 50g). Step 2 = If result ≥140 mg/dL, climb to the next step: 100g OGTT for 3 hours (heavier test, more steps). Remember: 50 is HALF of 100 — the screening is HALF the test. If you fail the first HALF, you take the FULL 100g OGTT. 24-28 weeks = third trimester entry (approximately 6-7 months).
Why it works
The staircase visual and the 'half' relationship between 50g and 100g create a logical, intuitive structure that the brain stores as a pattern rather than isolated numbers.
Example usage
Exam: A pregnant woman screens positive on the 50-g glucose challenge. What is the next step? Climb the staircase → 3-hour 100-g OGTT.
Recall trigger
Staircase: 50g first → fail at 140 → climb to 100g OGTT
GDM glycemic targets: Fasting <95, 1-hr postprandial <140, 2-hr postprandial <120 mg/dL
Memory aid
The DESCENDING STAIRCASE of sugar: Fasting starts at <95 (lowest number, most strict — you haven't eaten anything, so it should be lowest). After 1 hour of eating it climbs to <140. After 2 hours it drops back to <120 (halfway down). Remember: 95-140-120 like a hill — goes up then comes down, but NEVER goes above those ceilings. Mnemonic: '95 fasting, 140 at one, 120 at two — keep the baby in view.'
Why it works
Visualizing the numbers as a hill (up then down) creates a shape-based spatial memory that encodes the three values in correct order.
Example usage
Exam: What is the 2-hour postprandial glucose target in GDM? Picture the hill coming down → 120 mg/dL.
Recall trigger
Sugar hill: 95 fasting → 140 at 1-hr → 120 at 2-hr
GDM neonatal complication: Macrosomia (>4,000 g) due to fetal hyperinsulinemia → neonatal hypoglycemia at birth
Memory aid
Imagine a baby who has been force-fed ube ice cream (sugar) all pregnancy. The baby makes LOTS of insulin to handle all that sugar (fetal hyperinsulinemia → big baby = MACROSOMIA, over 4,000 g). Then at birth, mama's sugar supply is CUT OFF, but the baby's insulin factory is still running at full speed → blood sugar drops → NEONATAL HYPOGLYCEMIA. The baby is like an ube factory left running after the supplier closes — it keeps burning its own sugar until it crashes.
Why it works
The ube (Filipino purple yam dessert) analogy is culturally resonant and the factory metaphor logically explains the pathophysiology of neonatal hypoglycemia in a memorable narrative.
Example usage
Exam: A newborn of a GDM mother trembles and has poor tone. What is the likely cause? Recall the ube factory → neonatal hypoglycemia from fetal hyperinsulinemia.
Recall trigger
Ube factory still running after birth → too much insulin → neonatal hypoglycemia
Insulin is the safest glucose-lowering agent in pregnancy — does NOT cross the placenta
Memory aid
Picture insulin as a big friendly giant who is TOO BIG to fit through the placenta gate. It stays on the mother's side, does its job lowering maternal blood sugar, but never reaches the baby. Meanwhile, oral agents (metformin, sulfonylureas) are smaller and can sneak through. Insulin = the gentle giant that stays outside the fence. Always safe, never harms the fetus.
Why it works
The spatial visual (giant too big to fit through a gate) creates an intuitive understanding of why insulin is preferred — its molecular size prevents placental crossing.
Example usage
Exam: Which glucose-lowering medication is safest in pregnancy because it does not cross the placenta? The giant at the gate → Insulin.
Recall trigger
Giant at the placenta gate → too big to cross → insulin is safe for baby
Hyperemesis gravidarum electrolyte imbalance: Hypokalemia and metabolic alkalosis (loss of HCl from vomiting)
Memory aid
Story: 'Ate Liza has been vomiting every hour for three weeks. With every vomit, she loses gastric acid (HCl). Losing acid = METABOLIC ALKALOSIS (blood becomes too basic). And with all that vomiting and poor intake, her potassium is washing away = HYPOKALEMIA. She feels weak, her heart feels fluttery, and her urine has ketones (KETONURIA — her body is starving). The nurse checks: pH up, K+ down, ketones in urine — classic hyperemesis picture.'
Why it works
The story of Ate Liza (a relatable Filipino character) creates a pathophysiological narrative that links vomiting → acid loss → alkalosis + hypokalemia in a cause-effect chain.
Example usage
Exam: A pregnant woman with hyperemesis gravidarum would most likely have which electrolyte imbalance? Recall Ate Liza → Hypokalemia and metabolic alkalosis.
Recall trigger
Ate Liza vomiting → acid out → alkalosis + hypokalemia + ketonuria
First-line antiemetic for hyperemesis gravidarum: Pyridoxine (Vitamin B6) ± Doxylamine
Memory aid
Remember: 'Before you DROWN in vomiting, take your B6 LIFEGUARD.' Pyridoxine = Vitamin B6 = the LIFEGUARD on duty for nausea in pregnancy. It is ALWAYS first on the scene. Doxylamine is the BACKUP LIFEGUARD — comes in when B6 alone isn't enough. Together they form Team B6-Dox: safe, proven, first-line. If the sea is too rough (severe hyperemesis), call in the bigger team: metoclopramide, promethazine, ondansetron.
Why it works
The lifeguard metaphor creates a rescue hierarchy (first-line vs. second-line) that maps naturally onto clinical decision-making, making it easy to recall which drug comes first.
Example usage
Exam: What is the first-line antiemetic for hyperemesis gravidarum? B6 lifeguard → Pyridoxine (Vitamin B6) ± Doxylamine.
Recall trigger
B6 lifeguard → Pyridoxine first-line; Doxylamine = backup
Preeclampsia pathophysiology: Generalized vasospasm → reduced perfusion to all organs (placenta, kidney, liver, brain)
Memory aid
Imagine the blood vessels as garden hoses in a barangay water system. In preeclampsia, someone KINKS all the hoses at the same time (generalized vasospasm). Water pressure builds up behind the kink (high blood pressure), but the gardens (organs) get almost no water (reduced perfusion). The placenta-garden wilts (fetal growth restriction), the kidney-garden dries up (proteinuria, oliguria), the liver-garden cracks (RUQ pain), and the brain-garden burns (headache, seizures). Fluid leaks out of the kinked hoses into the soil (edema) but the hoses themselves have less water inside (intravascular volume depletion).
Why it works
The barangay garden hose analogy maps the entire pathophysiology onto a concrete, spatially vivid image familiar in Filipino community life.
Example usage
Exam: What is the primary pathophysiological mechanism in preeclampsia? Recall the kinked hose → Generalized vasospasm causing endothelial dysfunction and reduced organ perfusion.
Recall trigger
Kinked barangay hose → vasospasm → high BP + low organ perfusion + edema

Formula mnemonics
MgSO4 Loading Dose: 4–6 g IV over 15–30 minutes
Mnemonic
DOUBLES LOAD: [4,6] and [15,30] — both pairs are doubles apart. Four-Six and Fifteen-Thirty. Say it fast: 'Four-to-six in fifteen-to-thirty!'
When to use
At the START of MgSO4 therapy for preeclampsia with severe features or eclampsia — given ONCE to rapidly achieve therapeutic serum levels
What each part means
4-6 g = the amount of magnesium sulfate in grams pushed into the IV as a loading bolus; 15-30 minutes = the time window over which it is given slowly enough to avoid respiratory arrest
MgSO4 Maintenance Dose: 1–2 g/hour via continuous IV infusion
Mnemonic
ONE TO TWO, every hour steady — 'After the load, slow and ready: one to two grams, keep mama steady.'
When to use
After the loading dose is complete — continued for 24-48 hours postpartum or until clinically stable
What each part means
1-2 g = hourly rate of magnesium infused to maintain therapeutic serum levels; /hour = this is a RATE, always on an infusion pump
MgSO4 Therapeutic Range: 4–7 mEq/L serum level
Mnemonic
Rice cooker sweet spot: Below 4 = undercooked (seizure risk); 4-7 = perfect; Above 7 = overcooked (toxicity). 4 to 7 = SAFE ZONE.
When to use
Use when interpreting serum magnesium lab results drawn during therapy to determine if dose adjustment is needed
What each part means
4 mEq/L = minimum effective level for seizure prevention; 7 mEq/L = upper safe limit; above this, toxicity signs appear progressively
Calcium Gluconate Antidote Dose: 1 g (10 mL of 10% solution) IV over ~3 minutes
Mnemonic
1-10-3 Countdown to save a life: 1 gram, 10 mL, 3 minutes. Countdown: 3... 10... 1. The syringe is yellow and ALWAYS at the bedside.
When to use
When MgSO4 toxicity is confirmed — absent DTRs, RR under 12/min, or cardiac arrest; given immediately while stopping the magnesium infusion
What each part means
1 g = the total dose of calcium gluconate; 10 mL = the volume of a standard 10% calcium gluconate ampule; 3 minutes = the slow IV push time to avoid cardiac arrhythmia
GDM Glycemic Targets: Fasting <95, 1-hr PP <140, 2-hr PP <120 mg/dL
Mnemonic
The Sugar Hill: Start at 95 (fasting, flat ground), rise to 140 (1-hour peak), come down to 120 (2-hour, still elevated but dropping). Never exceed the hilltop numbers: 95-140-120.
When to use
When monitoring and evaluating glycemic control in a pregnant woman diagnosed with GDM — determines whether diet alone is sufficient or insulin must be added
What each part means
Fasting <95 = blood glucose before any meal; 1-hr PP <140 = peak glucose 1 hour after eating (strictest limit); 2-hr PP <120 = glucose 2 hours after eating (should be declining)
GDM Screening Threshold: 50-g GCT at 24–28 weeks; result ≥140 mg/dL triggers 3-hour 100-g OGTT
Mnemonic
STAIRCASE: Step 1 = 50g at 24-28 weeks (half the test); Fail at ≥140 = climb to Step 2: 100g OGTT for 3 hours (full test). 50 is half of 100 — first step is lighter.
When to use
Universally applied to all pregnant women between 24-28 weeks of gestation as part of routine prenatal care in Philippine clinical settings
What each part means
50-g GCT = glucose challenge test, non-fasting, 1-hour; 24-28 weeks = standard screening window (early second trimester to early third); ≥140 mg/dL = abnormal threshold; 100-g OGTT = diagnostic test, fasting, with blood draws at 1, 2, and 3 hours
Quick recall chains
Magnesium Toxicity Signs in Order (Earliest to Most Severe)
Recall test
What is the FIRST sign of MgSO4 toxicity that tells you to hold the infusion?
Memory chain
Follow Nurse Rey's story: The patient's KNEE STOPS KICKING (DTRs gone — hold the mag!), then she BREATHES SLOWLY like a tired turtle (RR under 12), then the FOLEY BAG is almost empty (oliguria, under 30 mL/hr), then she GOES QUIET AND PALE (decreased LOC), and finally the MONITOR FLATLINES (cardiac arrest). Each step is a warning — stop at the first sign (absent DTRs) before the flatline.
Items to remember
- Loss of deep tendon reflexes (earliest — ~8-10 mEq/L)
- Respiratory depression — RR under 12/min (~10-12 mEq/L)
- Oliguria — urine output under 30 mL/hr
- Decreased level of consciousness
- Cardiac and respiratory arrest (most severe)
Steps When an Eclamptic Seizure Occurs
Recall test
Name the first three priority nursing actions during an eclamptic seizure in correct order.
Memory chain
Nurse Ana's action plan: She TURNS (left side), WAITS (no restraint, no mouth packing), CALLS (shouts for help + checks the clock), OXYGENATES (after seizure: O2), SUCTÍONS (clears airway), CHECKS THE BABY (FHR), and WHEELS TO DELIVERY (only cure). Acronym: TWCOSCD — 'Turn, Wait, Call, Oxygenate, Suction, Check baby, Deliver.'
Items to remember
- Turn patient to LEFT SIDE (airway, safety)
- Do NOT restrain
- Do NOT force anything into mouth
- Call for help and note time of seizure
- Provide oxygen after the seizure
- Suction secretions
- Assess fetal heart rate
- Prepare for delivery — it is the only cure
MgSO4 Monitoring Parameters Before and During Infusion (DRU)
Recall test
What three assessments must be performed before administering each dose of MgSO4? State the acceptable values for each.
Memory chain
DRU — 'Every nurse must DRU before giving the mag.' D = DTRs present (knee kicks), R = Respirations ≥12/min (count for a full minute), U = Urine ≥30 mL/hr (check the Foley bag). If ANY DRU parameter is abnormal, HOLD the infusion and notify the physician. DRU is your GREEN LIGHT before each dose.
Items to remember
- Deep tendon reflexes — must be PRESENT
- Respiratory rate — must be ≥12 per minute
- Urine output — must be ≥30 mL per hour
HELLP Syndrome Components and Dangers
Recall test
What does each letter in HELLP stand for, and what critical nursing action is PROHIBITED with this diagnosis?
Memory chain
HELLP is a broken traffic light: RED (hemolysis — blood breaking), YELLOW (liver enzymes — bile color warning), GREEN OFF (no platelets — low platelet green light gone). The danger zone: broken lights = accidents ahead (liver rupture, DIC, abruption). Remember: NEVER palpate the liver in HELLP — a hard palpation can cause RUPTURE. The traffic light is already broken; don't smash it further.
Items to remember
- H — Hemolysis (red cell destruction)
- E — Elevated Liver enzymes (hepatic damage)
- L — Low Platelets (thrombocytopenia)
- L — risk of Liver rupture (DO NOT palpate liver)
- P — risk of DIC, abruption, death
Hyperemesis Gravidarum Assessment Chain
Recall test
What electrolyte imbalance and acid-base disturbance are characteristic of hyperemesis gravidarum, and what is the physiological reason for each?
Memory chain
Ate Liza's downward spiral: She VOMITS (severe, persistent), LOSES WEIGHT (over 5% gone), DRIES UP (dehydration — dry mouth, fast heart, dark urine), BURNS FAT (ketonuria — body starving), LOSES POTASSIUM (hypokalemia — fluttery heart, weakness), and her BLOOD TURNS BASIC (metabolic alkalosis — pH rising from acid loss). Six steps down the spiral: V-W-D-K-K-A (Vomit, Weight loss, Dehydration, Ketones, hypoKalemia, Alkalosis).
Items to remember
- Severe nausea and vomiting — beyond normal morning sickness
- Weight loss >5% of pre-pregnancy weight
- Dehydration signs — dry mucous membranes, tachycardia, concentrated urine
- Ketonuria — starvation metabolism
- Hypokalemia — from vomiting and poor intake
- Metabolic alkalosis — from HCl loss
