A nurse is preparing to administer verapamil to a client who is 2 days post-myocardial infarction. The nurse should monitor the client for which of the following outcomes as a therapeutic response to the medication?
Increased heart rate
Increased blood pressure
Decreased pulmonary congestion
Decreased anginal pain
The Correct Answer is D
Rationale:
A. Verapamil is a calcium channel blocker that typically decreases heart rate rather than increases it. Therefore, an increased heart rate would not be a therapeutic response to this medication.
B. Verapamil works to lower blood pressure by inhibiting calcium influx into the vascular smooth muscle. An increase in blood pressure would not be an expected therapeutic outcome.
C. While verapamil may help with heart function, the primary therapeutic response is not specifically measured by decreased pulmonary congestion. This outcome may not be directly observable in the early treatment phases post-myocardial infarction.
D. Verapamil is effective in reducing anginal pain by decreasing myocardial oxygen demand through lowering heart rate and contractility. Thus, a decrease in anginal pain would be a direct therapeutic response to the medication.

Correct Answer is B
Explanation
Rationale:
A. "I will stop taking this medication when I feel better.": The full course of antibiotics should be completed to ensure the infection is fully treated and to prevent antibiotic resistance. This statement shows a misunderstanding.
B. "This medication can increase my risk of sunburn.": Ciprofloxacin can increase sensitivity to sunlight, making the skin more prone to sunburn. Clients are advised to avoid excessive sun exposure and use sunscreen.
C. "I should take my medication daily in the morning with milk.": Ciprofloxacin should not be taken with dairy products as calcium can interfere with the absorption of the medication, reducing its effectiveness.
D. "I should stop taking my birth control pills while I'm taking this medication.": Ciprofloxacin does not require discontinuation of birth control pills, though clients should be aware of the potential for antibiotic interactions to reduce contraceptive effectiveness.
Correct Answer is C
Explanation
Rationale:
A. Muscle rigidity of the extremities: This finding is more indicative of hyperkalemia or severe electrolyte imbalances but is not a common symptom of hypokalemia.
B. Bounding radial pulses: This finding is more associated with hypervolemia or hyperkalemia, not with hypokalemia caused by furosemide.
C. Depressed deep tendon reflexes: This is the correct response, as low potassium levels (hypokalemia) can lead to diminished reflexes due to its role in neuromuscular function.
D. Increased bowel motility: This is incorrect, as hypokalemia typically results in decreased bowel motility and may cause constipation rather than increased motility.
