Question 1 of 5
A nurse is caring for a client who is taking triamterene. For which of the following laboratory values should the nurse withhold the medication?
Correct Answer: B
Rationale: A potassium level of 5.3 mEq/L is elevated, and withholding triamterene, a potassium-sparing diuretic, prevents hyperkalemia.
Question 2 of 5
A nurse is caring for a client who has diabetes mellitus and is taking pioglitazone. The nurse should plan to monitor the client for which of the following adverse effects?
Correct Answer: A
Rationale: Pioglitazone, a thiazolidinedione, can cause fluid retention and edema, which requires monitoring, especially in clients with diabetes.
Question 3 of 5
A nurse is administering naloxone to a client who has developed an adverse action to morphine. The nurse should identify which of the following findings as a therapeutic effect of naloxone?
Correct Answer: B
Rationale: Naloxone counteracts opioid effects, particularly respiratory depression, so increased respiratory rate is the expected therapeutic outcome.
Question 4 of 5
A nurse is teaching a client who has a prescription for ferrous gluconate. Which of the following statements by the client indicates an understanding of the teaching?
Correct Answer: D
Rationale: Staying upright for at least 15 minutes after taking ferrous gluconate helps prevent esophageal irritation, which can occur if the medication remains in contact with the esophageal lining. Taking it with milk or antacids can reduce absorption, and black stools are an expected side effect.
