A nurse is caring for a client who has been prescribed prochlorperazine (Compazine) for postoperative nausea. Which of the following reported signs can indicate a potential complication of this medication?
Nausea
Prolonged QT interval
Restlessness
Vomiting
The Correct Answer is C
A. Nausea is the symptom prochlorperazine is intended to treat, so its occurrence would suggest that the medication is not effective rather than being a complication.
B. Prolonged QT interval is not a typical complication of prochlorperazine; it is more commonly associated with medications like ondansetron.
C. Restlessness can indicate akathisia, a potential extrapyramidal side effect of prochlorperazine. This condition involves an intense feeling of restlessness and the need to move, commonly associated with dopamine antagonists.
D. Vomiting is a symptom treated by prochlorperazine and would likely occur due to inadequate control rather than being a complication of the drug itself.

Correct Answer is D
Explanation
A. "This medication may cause increased libido." This is incorrect. Cimetidine (Tagamet) can cause side effects such as decreased libido, especially in men. This occurs because the drug inhibits the action of certain hormones, leading to sexual dysfunction.
B. "You may take this medication with antacids to prevent stomach upset." This is incorrect. Cimetidine should not be taken with antacids because antacids can reduce its absorption and effectiveness. It is advised to space the administration of cimetidine and antacids by at least 1 hour.
C. "This medication will neutralize your stomach acid." This is incorrect. Cimetidine works by blocking histamine receptors (H2 receptors), which reduces the production of stomach acid but does not neutralize it.
D. "This medication may cause decreased libido." This is correct. One of the side effects of cimetidine is reduced libido, particularly in male clients, due to its anti-androgenic effects.
Correct Answer is B
Explanation
A. Metformin does not typically cause hypoglycemia because it works by decreasing hepatic glucose production and improving insulin sensitivity, not directly lowering blood sugar levels.
B. Somnolence could indicate lactic acidosis, a rare but serious adverse effect of metformin that warrants immediate medical attention.
C. Fluid retention is not a known adverse effect of metformin. Other medications, such as certain thiazolidinediones, are associated with this complication.
D. Hyperglycemia is not a typical adverse effect of metformin; instead, it helps manage blood glucose levels in clients with type 2 diabetes mellitus.
