Chapter 23 : Antianginal Drugs Questions
Question 1 of 5
A 74-year-old professional golfer has chest pain that occurs toward the end of his golfing games. He says the pain usually goes away after one or two sublingual nitroglycerin tablets and rest. What type of angina is he experiencing?
Correct Answer: A
Rationale: Classic (chronic stable) angina is triggered by exertion or stress, like golfing, and is relieved by rest or nitroglycerin. Variant and Prinzmetal angina involve vasospasm, and unstable angina is unpredictable and not necessarily exertion-related.
Question 2 of 5
A patient arrives in the emergency department with severe chest pain. The patient reports that the pain has been occurring off and on for a week now. Which assessment finding would indicate the need for cautious use of nitrates and nitrites?
Correct Answer: A
Rationale: Nitrates can cause hypotension, so a blood pressure of 88/62 mm Hg indicates cautious use due to the risk of further lowering blood pressure. Pulse rate, renal disease, and past myocardial infarction are not contraindications.
Question 3 of 5
A calcium channel blocker is prescribed for a patient, and the nurse provides instructions to the patient about the medication. Which instruction is correct?
Correct Answer: D
Rationale: Calcium channel blockers (CCBs) can cause constipation, which can be mitigated by a high-fiber diet and fluids. Chewing tablets, taking with grapefruit juice (which increases drug levels), or abrupt discontinuation are incorrect and unsafe.
Question 4 of 5
When applying transdermal nitroglycerin patches, which instruction by the nurse is correct?
Correct Answer: A
Rationale: Rotating application sites for transdermal nitroglycerin patches prevents skin irritation. The patch can be applied to any nonhairy area, not just the chest, and can remain on during swimming, but should be replaced if it comes off.
Question 5 of 5
A patient has been taking a beta blocker for 4 weeks as part of his antianginal therapy. He also has type 2 diabetes mellitus and hyperthyroidism. When discussing possible adverse effects, the nurse will include which information?
Correct Answer: D
Rationale: Beta blockers can cause hypoglycemia or hyperglycemia in diabetic patients, necessitating blood glucose monitoring. They may cause weight gain, not loss, and typically reduce heart rate. Hot tubs and saunas increase hypotension risk.
