Question 1 of 5
A client is taking a calcium channel blocker (CCB). The nurse knows to monitor for which of the following dangerous side effects of this medication?
Correct Answer: A
Rationale: CCBs can worsen heart failure by reducing cardiac contractility, a dangerous side effect. Drowsiness and headache are less severe, and hypertension is treated by CCBs.
Question 2 of 5
The nurse is assessing a client who suffers from panic disorder. Which SNRI drug can induce remission and prevent relapse for this disorder?
Correct Answer: A
Rationale: Venlafaxine, an SNRI, is effective for long-term panic disorder management. Escitalopram is an SSRI, alprazolam is short-term, and buspirone is for generalized anxiety.
Question 3 of 5
The clinic nurse is teaching a community class about Angiotensin-Converting Enzyme (ACE) inhibitors and Angiotensin II Receptor Blockers (ARBs). Which of the following should be included in the teaching?
Correct Answer: D
Rationale: Both ACE inhibitors and ARBs are contraindicated in pregnancy due to fetal harm risks. They treat hypertension and heart failure, and can affect potassium/WBC levels.
Question 4 of 5
The nurse is teaching the client prescribed verapamil to avoid which of the following foods?
Correct Answer: A
Rationale: Grapefruit increases verapamil levels by inhibiting metabolism, risking toxicity. Apples, bananas, and oranges have no significant interaction.
Question 5 of 5
The nurse is evaluating the therapeutic effects of nitroglycerin transdermal patches prescribed to a client 6 months ago. Which of the following statements by the client would indicate that the medication is effective?
Correct Answer: C
Rationale:
Tolerating exercise without pain indicates nitroglycerin effectively prevents angina, its primary goal. BP improvement, no attacks, and fewer headaches are less specific indicators.
