Question 1

A patient presents with acute onset of a cold, pale, pulseless left lower extremity. Which condition should the nurse suspect?

Accepted Answer

Acute arterial embolism

Answer

The classic presentation of acute arterial occlusion includes the six Ps: pain, pallor, pulselessness, poikilothermia, paresthesia, and paralysis.

Question 2

A patient with newly diagnosed atrial fibrillation asks why anticoagulation therapy is necessary. Which response by the nurse is most accurate?

Accepted Answer

The irregular rhythm causes blood to pool in the atria, increasing stroke risk from clot formation

Answer

Atrial fibrillation causes ineffective atrial contraction, leading to blood stasis and thrombus formation in the atria, significantly increasing embolic stroke risk.

Question 3

A nurse notes ST-segment elevation in leads II, III, and aVF on a 12-lead ECG. Which coronary artery is most likely occluded?

Accepted Answer

Right coronary artery

Answer

ST elevation in leads II, III, and aVF indicates an inferior wall myocardial infarction, which is most commonly caused by right coronary artery occlusion.

Question 4

A patient with chronic heart failure is prescribed carvedilol. Which assessment is most important before administering the first dose?

Accepted Answer

Baseline heart rate and blood pressure

Answer

Carvedilol is a beta-blocker that can cause bradycardia and hypotension; baseline heart rate and blood pressure must be assessed to ensure safe administration.

Question 5

A patient returns from cardiac catheterization with a radial artery access site. Which post-procedure assessment takes highest priority?

Accepted Answer

Evaluating neurovascular status of the affected hand including capillary refill and sensation

Answer

After radial artery catheterization, frequent neurovascular checks of the affected hand are essential to detect compromised circulation from hematoma or arterial occlusion.
