Which patient statement would help the nurse confirm a previous diagnosis of chronic stable angina?

Choice A rationale
A 59-year-old patient with unstable angina who has just returned from a percutaneous coronary intervention (PCI) should be prioritized for assessment. PCI is a procedure to open blocked or narrowed coronary arteries and can lead to complications such as re-occlusion of the artery or bleeding from the catheter insertion site. Furthermore, unstable angina is a condition that can progress to myocardial infarction if not managed effectively.
Choice B rationale
A 56-year-old patient with variant angina due to receive nifedipine (Procardia) requires monitoring, but is not the highest priority. Variant angina is a form of angina that occurs at rest, often with severe pain, but it is usually well-controlled with medications like nifedipine.
Choice C rationale
A 65-year-old patient who had a myocardial infarction (MI) 4 days ago and is anxious about discharge planned for today is a lower priority for assessment. While it’s important to address the patient’s anxiety and provide education about post-discharge care, this patient is not in immediate danger.
Choice D rationale
A 39-year-old patient with pericarditis complaining of sharp, stabbing chest pain requires assessment, but is not the highest priority. Pericarditis is inflammation of the pericardium, the sac-like covering of the heart, and while it can cause severe pain, it is not typically life- threatening.

Choice A rationale
Diltiazem does not increase the contractile force of the heart. In fact, it is classified as a negative inotrope, meaning it decreases the force of heart contractions.
Choice B rationale
While diltiazem can affect heart rhythm, it does not specifically reduce heart palpitations. Its primary effect is to slow the heart rate and relax the blood vessels.
Choice C rationale
Diltiazem is a calcium channel blocker used to manage cardiovascular conditions such as hypertension, chronic stable angina, atrial fibrillation, and Prinzmetal’s angina. It works by inhibiting the calcium influx into cardiac and vascular smooth muscle during depolarization. This results in vasodilation, or the widening of blood vessels, which can help decrease coronary artery spasms, a characteristic feature of Prinzmetal’s angina.
Choice D rationale
Diltiazem does not prevent the formation of plaque in the coronary arteries. It primarily acts to relax the blood vessels and slow the heart rate.
