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 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.
Correct Answer is D
Explanation
A. Regular insulin – This is incorrect. Regular insulin would exacerbate hypoglycemia since it lowers blood glucose levels. Administering insulin in this scenario would worsen the client's condition.
B. Diphenhydramine (Benadryl) – This is incorrect. Diphenhydramine is an antihistamine and has no role in treating hypoglycemia or insulin toxicity.
C. Metformin (Glucophage) – This is incorrect. Metformin is an oral hypoglycemic agent and is not suitable for immediate treatment of insulin-induced hypoglycemia.
D. Glucagon (GlucaGen) – This is correct. Glucagon raises blood glucose by promoting glycogen breakdown in the liver and is the treatment of choice for severe hypoglycemia in clients unable to swallow or follow commands.
