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 D
Explanation
Rationale:
A. This statement is incorrect because omeprazole is not an antibiotic and does not kill bacteria; it is a proton pump inhibitor (PPI) that reduces acid production.
B. This statement is incorrect; omeprazole does not neutralize stomach acid, but rather decreases its production.
C. This statement is also incorrect; omeprazole does not coat the stomach lining; it works by inhibiting the proton pumps in the stomach lining to reduce acid secretion.
D. This statement is correct; omeprazole reduces stomach acid production, which is beneficial for managing GERD symptoms.
Correct Answer is C
Explanation
Rationale:
A. Monitoring alanine aminotransferase is important for liver function, but it is not the priority for a client on captopril.
B. Thyroid-stimulating hormone is not directly impacted by captopril and is not the priority lab value to monitor in this context.
C. Potassium is the priority laboratory value to monitor because captopril, an ACE inhibitor, can lead to hyperkalemia (elevated potassium levels), which can cause serious cardiac complications.
D. While magnesium levels are important to monitor, they are not specifically related to captopril therapy as potassium levels are.
