Question

A nurse is educating a client about the action of aspirin during cardiac events. Which of the following statements by the nurse should be included in the teaching?

Answer 1

Correct Answers:

Taking aspirin will prevent platelet aggregation.

Rationale :

🩸Aspirin irreversibly inhibits the COX-1 enzyme, reducing thromboxane A₂ synthesis and thereby decreasing platelet aggregation.

💊The antiplatelet effect lowers the risk of arterial thrombus formation that can occlude coronary vessels during acute cardiac events.

⏰Early inhibition of platelet clumping limits clot extension and reduces the chance of reinfarction.

🔬Low doses (75–325 mg) are sufficient for antiplatelet activity, distinguishing this use from its analgesic and anti-inflammatory effects.

📌Core Message

Aspirin’s antiplatelet action via COX-1 inhibition prevents platelet aggregation in acute cardiac events.

Answer 2

Correct Answers:

Maintain a BMI less than 25.

Rationale :

⚖️Maintaining a BMI under 25 reduces cardiac workload by decreasing myocardial oxygen demand.

💓Lower body weight improves ventricular function and minimizes strain on the heart in cardiomyopathy.

🏃Appropriate weight management lessens the frequency of angina episodes by preventing excessive exertion–related demand.

📉A BMI less than 25 is linked to improved cardiac outcomes and reduced complications in heart disease.

📌Core Message

A BMI under 25 decreases cardiac workload and oxygen demand, preventing angina episodes.

Answer 3

Correct Answers:

Report any dark urine after starting the medication.

Rationale :

🚨Simvastatin–induced hepatotoxicity can elevate bilirubin levels, causing dark urine as an early indicator of liver injury.

💥The medication’s risk for rhabdomyolysis leads to myoglobin release into the bloodstream, which appears in urine as a dark discoloration.

🧪Monitoring for changes in urine color facilitates timely assessment of muscle breakdown and prevention of kidney damage.

⌛Early reporting of dark urine enables rapid intervention to mitigate serious adverse effects associated with simvastatin.

📌Core Message

Dark urine signals potential hepatotoxicity or rhabdomyolysis from simvastatin and requires prompt reporting.

Answer 4

Correct Answers:

The client has a history of bronchial asthma.

Rationale :

🌬Beta-1 selective blockers like atenolol can still affect bronchial beta-2 receptors at higher doses, leading to bronchoconstriction.

⛔Constriction of airways can precipitate bronchospasm in clients with bronchial asthma, causing respiratory distress.

❤️While atenolol reduces cardiac workload, the risk to pulmonary function outweighs benefits in asthmatic patients.

🔒Choosing alternative antihypertensives prevents exacerbation of respiratory conditions and ensures client safety.

📌Core Message

Atenolol poses bronchospasm risk in asthma due to nonspecific beta blockade, contraindicating its use.

Answer 5

Correct Answers:

Complete an electrocardiogram.

Rationale :

🕒Timely ECG acquisition identifies acute ischemic changes and guides immediate management within the first 10 minutes of chest pain onset.

💓Waveform analysis for ST-segment deviations distinguishes between unstable angina and myocardial infarction, informing treatment decisions.

⚡Rapid detection of arrhythmias and conduction abnormalities is critical to prevent complications and reduce mortality.

📊Diagnostic tests like CRP levels and echocardiograms provide supplementary information but are not the priority in acute chest pain evaluation.

📌Core Message

An ECG offers rapid detection of ischemia and arrhythmias, making it the priority in chest pain assessment.

Answer 6

Correct Answers:

Diabetes is a risk factor.
Inactivity is a risk factor.
Diet is a risk factor.

Rationale :

🍬Chronic hyperglycemia in diabetes damages endothelium and accelerates plaque formation in arteries.

🏃Sedentary lifestyle decreases HDL cholesterol and impairs vascular health, promoting atherosclerosis.

🥦Unhealthy dietary patterns high in saturated fats and cholesterol elevate serum lipid levels, contributing to plaque buildup.

⚖️Addressing these modifiable factors through lifestyle changes can significantly reduce cardiovascular risk.

📌Core Message

Modifying diabetes, physical inactivity, and diet can lessen atherosclerosis risk.

Answer 7

Correct Answers:

PT/INR level.

Rationale :

⏱Warfarin prolongs prothrombin time by inhibiting vitamin K–dependent clotting factors, making PT/INR the standard for monitoring.

🧪INR standardizes PT results across labs, ensuring consistent assessment of anticoagulation intensity.

⚖️Maintaining an INR within the therapeutic range balances bleeding and thrombotic risks.

🔒Tests like PTT or D-dimer do not accurately reflect warfarin’s effect on the extrinsic clotting pathway.

📌Core Message

PT/INR monitoring ensures therapeutic anticoagulation and minimizes bleeding or clotting complications with warfarin.

Answer 8

Correct Answers:

The test will detect abnormal rhythms.

Rationale :

📈An electrocardiogram records the heart’s electrical activity, enabling identification of arrhythmias.

⏳Real-time waveform analysis reveals deviations in PQRST intervals, critical for diagnosing conduction disturbances.

🏷ECG does not directly measure ejection fraction or visualize blood flow; those require echocardiography or imaging.

🛌Positioning supine or slight side-lying is standard for ECG lead placement, but the primary purpose remains rhythm detection.

📌Core Message

An ECG primarily identifies electrical conduction abnormalities and arrhythmias.

Answer 9

Correct Answers:

Heparin and warfarin work together to prevent future clots from forming.

Rationale :

🩹Heparin provides immediate anticoagulation by activating antithrombin III to inhibit clotting factors.

⌛Warfarin takes several days to reduce vitamin K–dependent factors, so heparin bridges until warfarin reaches therapeutic levels.

🔗Combined therapy prevents new thrombus formation during the warfarin initiation period.

⚠️While both increase bleeding risk, their synergistic timing optimizes safety and efficacy in clot prevention.

📌Core Message

Heparin bridges warfarin onset to ensure continuous anticoagulation and prevent new clot formation.

Answer 10

Correct Answers:

I should take one tablet at the first indication of chest pain.

Rationale :

⏲Nitroglycerin acts rapidly to vasodilate coronary arteries and reduce myocardial oxygen demand at the initial onset of chest pain.

💊Administration at first symptoms prevents ischemia from worsening and limits infarct size.

🕒Re-dosing every 5 minutes is allowed up to three doses, but taking one tablet every 15 minutes delays relief and is incorrect.

📚Timing based on chest pain rather than blood pressure or bedtime ensures prompt relief.

📌Core Message

Early nitroglycerin use at chest pain onset maximizes coronary vasodilation and pain relief.
