Examiner Tip

For a 1-mark definition, the examiner is looking for two elements in one sentence: what is narrowed (coronary arteries) and why (atherosclerosis/plaque). Include both in a single clear sentence.

Model Answer

Coronary artery disease (CAD) is the progressive narrowing of the coronary arteries, most commonly due to atherosclerosis — the buildup of fatty fibrous plaque (atheroma) in the arterial intima — which reduces blood flow and oxygen supply to the myocardium.

Question Type

Answer Structure

• Line 1: State the definition with the cause (atherosclerosis/plaque buildup) and the effect (reduced myocardial blood flow) [1 mark]

Scoring Breakdown

Common Mark Deductions

• Writing only 'blocked arteries' without mentioning atherosclerosis — too vague for a 1-mark definition
• Confusing CAD with MI — CAD is the underlying disease, MI is an acute event
• Omitting the word 'coronary' — the definition must specify which arteries are affected

Key Phrases To Include

• progressive narrowing of coronary arteries
• atherosclerosis
• plaque / atheroma
• reduced blood flow to the myocardium

Examiner Tip

For differentiation questions, the examiner awards one mark per condition described correctly. Focus on the key distinguishing features: trigger, relief, and clinical significance. The phrase 'not relieved by nitroglycerin' is a high-yield phrase for unstable angina.

Model Answer

Stable (exertional) angina is predictable chest pain triggered by physical exertion or emotional stress; it lasts less than 5–15 minutes and is relieved by rest and sublingual nitroglycerin. Cardiac biomarkers remain normal because there is no myocardial necrosis. Unstable angina is a form of acute coronary syndrome (ACS) where chest pain occurs at rest or with minimal exertion; it is more frequent, more severe, and is NOT relieved by rest or nitroglycerin. Cardiac biomarkers are also normal (no necrosis), but it signals impending myocardial infarction and requires urgent intervention.

Question Type

short_answer

Answer Structure

• Point 1: Define stable angina — trigger (exertion/stress), duration (under 15 min), relief (rest + nitroglycerin), biomarkers normal [1 mark]
• Point 2: Define unstable angina — occurs at rest, not relieved by nitroglycerin, part of ACS, signals impending MI, biomarkers normal [1 mark]

Scoring Breakdown

Common Mark Deductions

• Saying unstable angina has elevated troponin — it does NOT; elevated troponin indicates MI, not unstable angina
• Failing to mention that stable angina is relieved by nitroglycerin — this is the key differentiating feature
• Writing the same point twice in different words instead of two distinct differentiating points

Examiner Tip

When asked to 'list' risk factors, you earn marks per correct item. Add a brief one-phrase explanation (e.g., 'damages endothelium') to demonstrate clinical understanding and secure full marks even if the examiner has flexibility in scoring.

Model Answer

Non-modifiable risk factors: (1) Increasing age — risk increases progressively with age; (2) Male sex — men are at higher risk, though women's risk equalizes after menopause. Modifiable risk factors: (1) Hypertension — elevated blood pressure damages the arterial endothelium, promoting atherosclerosis; (2) Dyslipidemia (high LDL, low HDL) — excess LDL deposits in arterial walls forming plaques. Other modifiable factors include diabetes mellitus, cigarette smoking, obesity, and physical inactivity.

Diagnostics — Cardiac Biomarkers

Difficulty

Examiner Tip

The word 'confirms' is critical when writing about troponin. Examiners look for the concept that troponin proves irreversible necrosis has occurred. Mention 'serial measurements' to show you understand how troponin is used in clinical practice.

Model Answer

Troponin (troponin I and troponin T) is the cardiac biomarker of choice in myocardial infarction because it is released into the bloodstream when myocardial cells undergo irreversible necrosis. Elevated serum troponin CONFIRMS the diagnosis of MI. Troponin is preferred over CK-MB because it is more CARDIAC-SPECIFIC (it is not found in significant amounts in skeletal muscle) and more SENSITIVE — it rises earlier (within 3–6 hours of onset), stays elevated longer (7–14 days), and can detect even small areas of myocardial necrosis. Serial troponin measurements are drawn to confirm the diagnosis.

Question Type

short_answer

Answer Structure

• Point 1: Significance of troponin — confirms myocardial necrosis in MI, released from damaged myocardial cells [1 mark]
• Point 2: Why preferred over CK-MB — higher cardiac specificity, greater sensitivity, rises earlier, stays elevated longer [1 mark]

Scoring Breakdown

Common Mark Deductions

• Saying 'troponin is elevated in angina' — incorrect; troponin is NORMAL in angina (no necrosis) and elevated only in MI
• Confusing troponin with BNP (B-type natriuretic peptide) — BNP indicates heart failure, not MI
• Failing to state WHY troponin is preferred — just saying 'it is the best test' without reasoning earns no marks

Nursing Management of MI

Examiner Tip

For priority nursing intervention questions, the NLE rewards answers that pair the ACTION with its RATIONALE. Write: 'Do [specific action with dose/route] to [achieve specific outcome].' Three well-structured action-rationale pairs will score full marks consistently.

Model Answer

Priority nursing interventions for a patient with suspected MI within the first 10 minutes: 1. Obtain a 12-lead ECG immediately (within 10 minutes of presentation) — to confirm ST-segment elevation (STEMI) or ST depression/T-wave inversion (NSTEMI), which determines the urgency and type of reperfusion therapy required. 2. Administer chewable Aspirin 160–325 mg orally as ordered — Aspirin inhibits platelet aggregation, reducing clot propagation and mortality. Chewing accelerates absorption. This is often the first-priority drug in ACS. 3. Establish IV access and draw cardiac biomarkers (troponin, CK-MB) — IV access enables immediate drug administration, and serial troponin measurements confirm or rule out myocardial necrosis to guide definitive management.

Question Type

short_answer

Answer Structure

• Intervention 1: 12-lead ECG within 10 minutes — state the action AND the rationale [1 mark]
• Intervention 2: Administer chewable Aspirin 160–325 mg — state the action, dose, route, and rationale [1 mark]
• Intervention 3: Establish IV access and draw cardiac markers — state the action AND the rationale [1 mark]

Scoring Breakdown

Common Mark Deductions

• Writing the action without the rationale — examiners expect both; 'give oxygen' alone earns half marks
• Writing 'give oxygen' as a first priority without qualifying it as 'only if hypoxic (SpO₂ < 90–94%)' — routine oxygen is no longer recommended and may show outdated knowledge
• Listing only assessments (like 'assess pain') without including interventions — the question asks for interventions, not assessments
• Not specifying the form of aspirin as chewable — this is clinically significant and may cost a mark

Key Phrases To Include

ACS Management — Nitroglycerin

Difficulty

Examiner Tip

Nitroglycerin administration is a high-frequency NLE topic. The three contraindications (hypotension, RV/inferior MI, PDE-5 inhibitors) are almost always tested as a set. Memorize all three and always write the rationale — why it is contraindicated — to secure full marks.

Model Answer

Administration of Sublingual Nitroglycerin: Instructions to the patient: (1) Sit or lie down before taking nitroglycerin to prevent falls from sudden hypotension. (2) Place one tablet (0.3–0.4 mg) under the tongue and allow it to dissolve. (3) Check blood pressure before each dose. (4) If chest pain persists after 5 minutes, take a second tablet; if pain still persists after another 5 minutes, take a third tablet and immediately call emergency services (activate the code or call 911). A maximum of THREE doses may be given, 5 minutes apart. Store tablets in a dark, airtight, non-plastic container away from heat. Contraindications to Nitroglycerin: 1. Hypotension (systolic BP < 90 mmHg) — nitroglycerin further lowers blood pressure and can cause cardiovascular collapse. 2. Right ventricular (RV) MI or inferior MI — these patients are preload-dependent; nitroglycerin drops preload and can cause severe hypotension. 3. Recent use of phosphodiesterase-5 inhibitors (sildenafil/Viagra, tadalafil) within 24–48 hours — combined use causes profound, potentially fatal hypotension.

Question Type

Scoring Breakdown

Common Mark Deductions

• Not specifying the NUMBER of maximum doses (3) or the TIME interval (5 minutes) — these are clinically specific details worth marks
• Omitting the instruction to 'sit or lie down' — this is a patient safety point and a likely exam component

ACS Management — MONA Framework

Difficulty

hard

Template Id

T7

Examiner Tip

The modern nuances of MONA — especially restricting oxygen to hypoxic patients and reserving morphine for nitroglycerin-unresponsive pain — are the most heavily tested updates. Examiners reward students who demonstrate awareness of current evidence-based practice. Always write MONA in the prioritized sequence: Aspirin first.

Model Answer

The MONA mnemonic represents four initial pharmacologic interventions in ACS: Morphine, Oxygen, Nitroglycerin, and Aspirin. Current evidence has refined how each is applied: A — Aspirin (160–325 mg, chewable): Given FIRST and IMMEDIATELY. Inhibits platelet aggregation, reduces clot extension, and decreases mortality. Chewing accelerates absorption. This is the top-priority drug in ACS. N — Nitroglycerin (sublingual 0.3–0.4 mg): A vasodilator that relieves ischemic chest pain and reduces preload. Give up to 3 doses, 5 minutes apart, checking blood pressure between each dose. CONTRAINDICATED in hypotension, right ventricular MI, and with phosphodiesterase inhibitors. O — Oxygen: Modern nuance — give ONLY if the patient is hypoxic (SpO₂ below 90–94%). Routine oxygen in normoxic patients is no longer recommended and may worsen outcomes by causing vasoconstriction. M — Morphine: An opioid that relieves pain and anxiety and reduces myocardial oxygen demand. RESERVED for pain NOT relieved by nitroglycerin. Not given routinely because it may mask ongoing ischemia and has been linked to worse outcomes when overused. Monitor for respiratory depression and hypotension.

• Component O — Oxygen: modern nuance — only if hypoxic, SpO₂ threshold stated [0.75 marks]
• Component M — Morphine: purpose, modern restriction (reserved for NTG-unresponsive pain), side effects monitoring [0.75 marks]

Scoring Breakdown

Common Mark Deductions

• Describing old MONA without any modern nuance — the NLE increasingly tests the updated approach, especially for oxygen and morphine

MI — ECG Patterns and Nitroglycerin Contraindications

Difficulty

hard

Template Id

T8

Examiner Tip

ECG lead localization is tested frequently in NLE cardiovascular questions. Memorize: II, III, aVF = inferior (RCA); V1–V4 = anterior (LAD); I, aVL, V5–V6 = lateral (LCx). When you see inferior MI, immediately think: check for RV involvement before giving nitroglycerin.

Model Answer

The ECG pattern of ST-segment elevation in leads II, III, and aVF indicates an INFERIOR STEMI (ST-elevation myocardial infarction), which involves the right coronary artery (RCA) territory. This pattern is associated with right ventricular (RV) involvement in approximately 30–50% of inferior MIs. The most important contraindication to check before giving nitroglycerin in this patient is RIGHT VENTRICULAR (RV) MI or right ventricular infarction. In RV MI, the right ventricle is preload-dependent — it requires adequate filling pressure to maintain cardiac output. Nitroglycerin reduces preload (venous return) and can cause severe, life-threatening hypotension in this patient. Before administering nitroglycerin, the nurse must check the blood pressure and assess for signs of RV involvement (hypotension, elevated JVD, clear lung fields).

Question Type

Answer Structure

• Part 1: Identify the type of MI — inferior STEMI, leads II, III, aVF, RCA territory [1 mark]

Reperfusion Therapy — Thrombolytics

Difficulty

medium

Template Id

T9

Examiner Tip

NLE often presents a patient scenario and asks whether thrombolytics are safe. The key screening questions are: Is the patient bleeding anywhere? Have they had a stroke? Did they have recent surgery? Do they have a brain tumor? If yes to any of these, thrombolytics are contraindicated. Practice these as a quick mental checklist.

Model Answer

Absolute contraindications to thrombolytic therapy in STEMI: 1. Active internal bleeding (excluding menstruation) — thrombolytics dissolve clots systemically and will worsen life-threatening hemorrhage. 2. History of hemorrhagic stroke (any time) OR ischemic stroke within the previous 3 months — high risk of intracranial hemorrhage. 3. Intracranial neoplasm, arteriovenous malformation, or aneurysm — thrombolytics can cause fatal intracranial bleeding. 4. Recent major surgery or significant trauma within 3 months — dissolving the clot at the surgical site causes uncontrolled bleeding. 5. Severe, uncontrolled hypertension (systolic > 180 mmHg) — risk of intracranial hemorrhage is unacceptably high. (Any four of the above earn full marks; all five demonstrate excellence.)

STEMI vs. NSTEMI Management

Examiner Tip

The STEMI/NSTEMI comparison is a very high-yield NLE topic. The single most important differentiating point is the use of thrombolytics: STEMI yes, NSTEMI no. Write this distinction clearly and always provide the rationale. The door-to-balloon and door-to-needle time limits are specific numbers examiners look for.

Model Answer

STEMI (ST-Elevation Myocardial Infarction) vs. NSTEMI (Non-ST-Elevation Myocardial Infarction): ECG Findings: • STEMI: ST-segment ELEVATION in two or more contiguous leads, indicating complete transmural (full-thickness) coronary occlusion. Pathologic Q waves develop later. • NSTEMI: ST-segment DEPRESSION or T-wave inversion — NO ST elevation. Indicates partial or subendocardial ischemia/necrosis. Management Approach: • STEMI: Requires IMMEDIATE reperfusion. Preferred: Percutaneous Coronary Intervention (PCI) with a door-to-balloon time of UNDER 90 MINUTES. If PCI is unavailable: thrombolytic therapy within 6–12 hours (door-to-needle under 30 minutes). • NSTEMI: Initially managed medically with dual antiplatelet therapy (aspirin + clopidogrel/ticagrelor), anticoagulation (heparin), beta-blockers, and nitrates. Risk stratification determines timing of angiography and PCI. Use of Thrombolytics: • STEMI: Thrombolytics ARE USED when PCI is not available within 90 minutes — there is a complete clot to lyse. • NSTEMI: Thrombolytics are CONTRAINDICATED / NOT USED — because there is no complete occlusion; thrombolytics would increase bleeding risk without clinical benefit.

Question Type

Answer Structure

• ECG findings: ST elevation for STEMI vs. ST depression/T-wave inversion for NSTEMI — with brief explanation of what each indicates [1 mark]
• Management: STEMI requires immediate reperfusion (PCI < 90 min / thrombolytics < 30 min); NSTEMI requires initial medical management with risk stratification [1 mark]
• Thrombolytics: Used in STEMI (complete occlusion), NOT used in NSTEMI (no complete occlusion, bleeding risk without benefit) [1 mark]

Scoring Breakdown

Common Mark Deductions

• Saying thrombolytics can be used in NSTEMI — this is a critical error; thrombolytics are used ONLY in STEMI
• Confusing 'door-to-balloon' time for PCI (90 min) with 'door-to-needle' time for thrombolytics (30 min)

Nursing Process — Nursing Diagnoses in MI

Difficulty

T11

Examiner Tip

In nursing diagnosis questions, always write the FULL three-part PES format. 'Decreased Cardiac Output' is nearly always the priority diagnosis in acute MI because it directly threatens perfusion of all vital organs. Justify your priority choice with Maslow — this separates average answers from excellent ones.

Model Answer

Priority Nursing Diagnosis (based on Maslow's physiological needs — Circulation/Oxygenation): 1. Decreased Cardiac Output related to myocardial damage (necrosis), dysrhythmias, or altered contractility as evidenced by chest pain, hypotension, tachycardia, and cool clammy skin. This is the priority diagnosis because it addresses the physiological threat to life — compromised circulation can lead to cardiogenic shock, organ failure, and death. Per Maslow's hierarchy, circulation (a physiological need) takes precedence. Other Relevant Nursing Diagnoses: 2. Acute Pain related to myocardial ischemia and necrosis as evidenced by the patient reporting severe crushing substernal chest pain rated 9/10, diaphoresis, and grimacing. 3. Activity Intolerance related to decreased cardiac output and imbalance between oxygen supply and demand as evidenced by exertional dyspnea, fatigue, and inability to perform activities without chest pain.

Clinical Manifestations of MI — Typical vs. Atypical

Difficulty

medium

Template Id

T12

Examiner Tip

The atypical presentation of MI in women, elderly, and diabetics is a recurring NLE scenario. NLE questions often present a female patient with only fatigue and dyspnea and ask the nurse what to suspect. The correct answer is always: suspect MI and obtain an ECG and troponin immediately. Knowing the at-risk populations is essential.

Model Answer

Classic Presentation of MI: Severe, crushing, substernal chest pain that lasts more than 20–30 minutes and is NOT relieved by rest or nitroglycerin. The pain commonly radiates to the left arm, jaw, neck, or back. Associated symptoms include diaphoresis (cold, clammy sweating), nausea and vomiting, dyspnea, palpitations, hypotension, and a sense of impending doom. The patient typically appears pale, anxious, and distressed. Atypical Presentation of MI: Instead of chest pain, the patient may present with: unexplained fatigue or extreme tiredness, shortness of breath (dyspnea) without chest pain, indigestion or epigastric pain (mistaken for gastritis or peptic ulcer), back or jaw pain alone, or dizziness and syncope. A 'SILENT MI' may occur with no symptoms at all — the patient only discovers the MI on a routine ECG. Patient Populations Most Likely to Present Atypically: 1. Women — more likely to experience fatigue, dyspnea, nausea, and back pain rather than classic chest pain. 2. Older adults (elderly) — diminished pain perception; may present with confusion, weakness, or syncope. 3. Patients with diabetes mellitus — diabetic neuropathy impairs pain transmission, leading to silent MI or minimal symptoms.

Model Answer

NURSING MANAGEMENT OF THROMBOLYTIC THERAPY IN STEMI I. DEFINITION AND PURPOSE Thrombolytic (fibrinolytic) therapy involves the administration of clot-dissolving drugs — such as alteplase, reteplase, tenecteplase, or streptokinase — to dissolve the thrombus occluding the coronary artery in a STEMI patient. It is indicated when Percutaneous Coronary Intervention (PCI) is NOT available within 90 minutes. The goal is a DOOR-TO-NEEDLE TIME of UNDER 30 MINUTES, administered ideally within the first 6 hours (up to 12 hours) of symptom onset. The sooner thrombolytics are given, the more myocardium is salvaged ('time is muscle'). II. PRE-ADMINISTRATION NURSING RESPONSIBILITIES 1. Confirm ECG-confirmed STEMI (ST elevation) — thrombolytics are NOT used in NSTEMI. 2. Conduct thorough screening for ABSOLUTE CONTRAINDICATIONS: • Active internal bleeding (excluding menses) • History of hemorrhagic stroke (any time) OR ischemic stroke within the previous 3 months • Recent major surgery or significant trauma within 3 months (due to risk of surgical site hemorrhage) 3. Obtain baseline vital signs, neurological assessment, and coagulation studies (PT, aPTT). 4. Establish TWO large-bore IV lines — minimize arterial punctures and invasive procedures to reduce bleeding risk. 5. Educate the patient about the procedure and obtain informed consent per RA 9173 patient rights principles. III. NURSING MONITORING DURING AND AFTER THERAPY 1. Vital signs: Monitor blood pressure, heart rate, respiratory rate every 15 minutes — watch for hypotension and tachycardia indicating hemorrhagic shock. 2. Neurological status: Assess every 30–60 minutes — sudden change in level of consciousness, severe headache, or neurological deficit may indicate INTRACRANIAL HEMORRHAGE — the most feared complication. 3. Cardiac monitoring: Continuous cardiac monitoring on the bedside monitor — watch for reperfusion dysrhythmias (accelerated idioventricular rhythm, ventricular tachycardia) which may paradoxically indicate successful reperfusion. 4. Pain assessment: Monitor for relief of chest pain — relief of pain suggests successful reperfusion. Return of pain suggests re-occlusion. 5. ECG monitoring: Assess for return of ST segment toward baseline — a sign of successful reperfusion. 6. Signs of bleeding: Inspect IV sites, gums, urine (hematuria), stool (melena), skin (petechiae, ecchymosis). IV. MAJOR COMPLICATIONS 1. BLEEDING — the most common and dangerous complication; ranges from minor oozing at venipuncture sites to major internal hemorrhage. 2. INTRACRANIAL HEMORRHAGE — the most feared complication; presents with sudden severe headache, altered consciousness, or focal neurological deficits. Treat by stopping the thrombolytic immediately. 3. Reperfusion dysrhythmias — usually transient; may require antiarrhythmic treatment. 4. Hypotension and allergic reactions (especially with streptokinase). V. NURSING ACTIONS TO MINIMIZE BLEEDING RISK • Avoid all unnecessary arterial punctures and venipunctures. • Apply gentle, prolonged pressure to all puncture sites. • Avoid IM injections during thrombolytic therapy. • Use the smallest gauge catheter necessary. • Do NOT insert urinary catheter or nasogastric tube unless absolutely necessary. VI. REPERFUSION SIGNS (INDICATORS OF SUCCESSFUL THERAPY) • Sudden relief of chest pain • Return of ST segment toward baseline on ECG • Reperfusion dysrhythmias (e.g., accelerated idioventricular rhythm) • Peak of cardiac enzymes earlier than expected (washout phenomenon)

PHASES OF CARDIAC REHABILITATION Phase I — Inpatient/Acute Phase (Hospital): • Begins while the patient is still hospitalized (Day 1–5 post-MI). • Goals: prevent deconditioning, maintain independence in basic ADLs, and begin patient education. • Activities: bed rest initially, then gradual progression to sitting, dangling, standing, and supervised ambulation. • Education begins: explaining the disease, medications, and when to seek help. • Nursing role: continuous monitoring of vital signs, cardiac rhythm, and patient tolerance during activity. Phase II — Early Outpatient (Supervised Exercise Program): • Begins 1–3 weeks after discharge; conducted at a supervised cardiac rehabilitation center. • Duration: typically 6–12 weeks, 3 times per week. • Goals: progressive increase in exercise tolerance, continued risk factor modification, psychosocial support. • Monitoring: HR, BP, ECG rhythm during exercise sessions. Phase III — Long-term Maintenance: • Ongoing, lifelong phase; the patient exercises independently in a community or home setting. • Focus: sustaining lifestyle changes (diet, exercise, smoking cessation) and medication adherence. III. PATIENT TEACHING PRIORITIES 1. Nitroglycerin use: Teach correct administration — sit/lie down, place one tablet (0.3–0.4 mg) sublingually, check BP, repeat every 5 minutes up to 3 doses. If pain persists after 3 doses or 15 minutes, call emergency services immediately. Store in a dark, airtight (non-plastic) container away from heat and light. 2. Risk factor modification (primary and secondary prevention, aligned with DOH PhilPEN program): • STOP SMOKING completely — smoking is the most modifiable CAD risk factor. • Control blood pressure — target BP below 130/80 mmHg. • Control blood sugar in diabetics — target HbA1c below 7%. • Follow a heart-healthy diet: low in saturated fat, cholesterol, and sodium; high in fiber and vegetables. • Achieve and maintain healthy body weight. • Exercise regularly: at least 150 minutes of moderate aerobic exercise per week. • Manage stress through relaxation techniques. 3. Medication adherence: Emphasize the importance of taking ALL prescribed medications: • Dual antiplatelets (aspirin + clopidogrel/ticagrelor) — do NOT stop without physician instruction; stopping increases risk of stent thrombosis. • Beta-blockers (metoprolol) — do NOT stop abruptly; may cause rebound tachycardia. • Statins (atorvastatin) — take as prescribed; report muscle pain (rhabdomyolysis). • ACE inhibitors — report persistent cough; do not stop without guidance. 4. Return-to-activity guidance: Sexual activity and driving may generally be resumed within 4–6 weeks, per physician guidance. Avoid strenuous activity before clearance. 5. Warning signs — seek IMMEDIATE medical care for: chest pain lasting more than 5 minutes, new or worsening dyspnea, syncope, or palpitations.

Question Type

Answer Structure

• I. Definition of cardiac rehabilitation [0.5 mark]
• II. Three phases: Phase I (inpatient), Phase II (supervised outpatient), Phase III (long-term maintenance) — each with goals and activities [1.5 marks]
• III. Patient teaching — nitroglycerin use (correct technique and storage) [1 mark]
• III. Patient teaching — risk factor modification (at least 4 modifiable factors) [1 mark]
• III. Patient teaching — medication adherence and warning signs [1 mark]

Scoring Breakdown

Common Mark Deductions

• Describing only one or two phases of cardiac rehabilitation — all three phases are expected in a 5-mark answer
• Not including specific warning signs that require immediate care — vague advice like 'monitor symptoms' earns no marks
• Failing to mention nitroglycerin storage (dark, airtight container) — a classic patient teaching point always included in cardiac care curricula
• Not connecting risk factor modification to the Philippine DOH context (PhilPEN, NCD prevention programs) — this adds clinical relevance
• Writing all patient teaching as a single paragraph without structure — this makes it difficult for examiners to identify individual scoring points

Key Phrases To Include

• Phase I — inpatient
• Phase II — supervised outpatient exercise
• Phase III — long-term maintenance
• progressive ambulation
• risk factor modification
• smoking cessation
• sublingual nitroglycerin
• dark airtight container
• dual antiplatelet therapy
• do NOT stop abruptly
• DOH PhilPEN program
• warning signs — seek immediate care

Examiner Tip

Case study questions that present a woman with vague symptoms and ask for the diagnosis are testing your knowledge of atypical MI presentation. The key diagnostic clues are: (1) elevated troponin = necrosis = MI (not just angina); (2) ST depression = NSTEMI (not STEMI). Connecting all three clues — presentation, ECG pattern, and troponin — in one sentence earns the diagnosis mark efficiently.

Model Answer

Most Likely Diagnosis: NSTEMI (Non-ST-Elevation Myocardial Infarction). The patient presents with an ATYPICAL presentation of MI — common in women — with fatigue, jaw discomfort, and indigestion instead of classic crushing chest pain. The ECG showing ST-segment DEPRESSION in V1–V4 (not elevation) combined with ELEVATED TROPONIN confirms myocardial necrosis, consistent with NSTEMI. Priority Nursing Action: The nurse's priority action is to maintain continuous cardiac monitoring (bedside cardiac monitor/telemetry) and immediately notify the physician of the ECG findings and elevated troponin. The nurse should also: establish IV access, administer chewable aspirin 160–325 mg orally as ordered, keep the patient on bed rest in a semi-Fowler's position to reduce cardiac workload, and monitor for life-threatening dysrhythmias — particularly ventricular fibrillation, which is the leading cause of death in the early hours of MI.

Answer Structure

• Part 1: Correct diagnosis — NSTEMI, identify atypical presentation in a woman, link ST depression + elevated troponin to NSTEMI [1 mark]
• Part 2: Priority nursing action — cardiac monitoring, notify physician, aspirin, bed rest, monitor for VFib [1 mark]

Scoring Breakdown

Common Mark Deductions

• Diagnosing STEMI — the ECG shows ST DEPRESSION not elevation; this distinction is critical
• Saying this is angina (unstable angina) — troponin IS elevated, confirming necrosis = MI, not angina
• Listing only one nursing action without prioritization — the question asks for the nurse's PRIORITY action
• Not explaining why this woman presents atypically — missing the teaching point about women and MI

Key Phrases To Include

• NSTEMI
• atypical presentation
• common in women
• ST-segment depression
• elevated troponin — confirms necrosis
• continuous cardiac monitoring
• ventricular fibrillation — leading cause of early death
• chewable aspirin 160–325 mg
