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. A decrease in the amount of gastric acid production: Alosetron is not used to decrease gastric acid production. This effect is more associated with medications such as proton pump inhibitors or H2 blockers.
B. A decrease in the frequency of defecation: Alosetron is used to treat irritable bowel syndrome with diarrhea (IBS-D) by reducing bowel movement frequency and improving stool consistency.
C. An increase in gastric motility: Alosetron works by decreasing intestinal motility, which helps reduce diarrhea, not by increasing it.
D. An increase in the absorption of water into the intestine: Alosetron does not specifically increase water absorption into the intestine. Its primary effect is slowing intestinal transit to reduce diarrhea.
Correct Answer is D
Explanation
Rationale:
A. Cataracts are not a contraindication for cholinesterase inhibitors like neostigmine.
B. Hypertension is not a direct contraindication for cholinesterase inhibitor therapy, although caution may be exercised depending on the overall health status of the client.
C. Hypothyroidism is not contraindicated for cholinesterase inhibitors; however, it should be managed appropriately.
D. Peptic ulcer disease is a significant contraindication for cholinesterase inhibitors like neostigmine because these medications can increase gastric secretions and motility, potentially exacerbating ulcer conditions and leading to complications.
