Question 1 of 5

A client is receiving orlistat as part of a weight management program. Which ongoing assessment should be included in the plan of care to determine the effectiveness of the medication? Which ongoing assessment should be included in the plan of care to determine the effectiveness of the medication?

Correct Answer: C

Rationale: Orlistat reduces fat absorption to aid weight loss. Monitoring BMI, calculated from height and weight, directly assesses weight changes, making it the most relevant measure of the medication’s effectiveness.

Question 2 of 5

The nurse is administering sodium polystyrene sulfonate to a client in acute kidney injury (AKI). Which laboratory finding indicates that the medication has been effective? Which laboratory finding indicates that the medication has been effective?

A. Serum potassium level of 3.8 mEq/L (1.8 mmol/L). B. Hemoglobin level of 13.3 g/dL (135 g/L). C. Serum ammonia level of 30 µg/dL (17.62 µmol/L). D. Serum glucose level of 100 mg/dL (5.6 mmol/L).

Correct Answer: A

Rationale: Sodium polystyrene sulfonate treats hyperkalemia by exchanging sodium for potassium in the intestines. A serum potassium level of 3.8 mEq/L, within the normal range, indicates effective reduction of potassium levels.

Question 3 of 5

Which action should the nurse implement to assess the effectiveness of amlodipine? Which action should the nurse implement?

A. Measure the client’s blood pressure. B. Monitor the client’s serum electrolytes. C. Note the client’s serum calcium levels. D. Review the client’s intake and output.

Correct Answer: A

Rationale: Amlodipine, a calcium channel blocker, lowers blood pressure by relaxing blood vessels. Measuring blood pressure directly assesses its effectiveness.

Question 4 of 5

A client with generalized anxiety disorder (GAD) receives a new prescription for lorazepam. Which statement provided by the client requires additional instruction by the nurse? Which statement provided by the client requires additional instruction by the nurse?

A. Use relaxation techniques to reduce excessive anxiety. B. Avoid alcohol and other sedatives while taking the medication. C. Move slowly from a sitting position to a standing position. D. Stop taking the medication if intended effect is not immediate.

Correct Answer: D

Rationale: Stopping lorazepam abruptly if effects are not immediate can lead to withdrawal symptoms and rebound anxiety. The nurse should instruct the client to follow the prescribed regimen and consult the provider before discontinuing.

Question 5 of 5

A client with anemia secondary to chronic kidney disease (CKD) started a prescription for epoetin alfa two months ago. Which client finding best indicates that the medication is effective? Which client finding best indicates that the medication is effective?

A. Reports of increased energy levels and decreased fatigue. B. Food diary shows increased consumption of iron-rich foods. C. Hemoglobin level increased to 12 g/dL (7.45 mmol/L). D. Takes concurrent iron therapy without adverse effects.

Correct Answer: C

Rationale: Epoetin alfa stimulates red blood cell production. An increase in hemoglobin to 12 g/dL objectively indicates effective treatment of anemia.
