Chapter 23 : Antianginal Drugs Questions
Question 1 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 2 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 3 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.
Question 4 of 5
What action is often recommended to help reduce tolerance to transdermal nitroglycerin therapy?
Correct Answer: D
Rationale: Removing the transdermal nitroglycerin patch at night for 8 hours helps prevent tolerance by allowing a nitrate-free interval. Omitting doses, leaving patches on for 2 days, or cutting patches are incorrect and unsafe.
Question 5 of 5
While assessing a patient who is taking a beta blocker for angina, the nurse knows to monitor for which adverse effect?
Correct Answer: C
Rationale: Beta blockers commonly cause bradycardia due to their effect on slowing heart rate. They do not typically cause nervousness, hypertension, or dry cough (which is more associated with ACE inhibitors).
