Correct Answer: D

Rationale: The correct answer is D: Aspartate aminotransferase (AST) 60 units/L. An elevated AST level indicates liver damage, a side effect of methotrexate, and should be reported. Choices A, B, and C are within normal ranges and do not indicate potential complications related to methotrexate therapy.

Correct Answer: C

Rationale: A respiratory rate of 10/min indicates respiratory depression, a serious adverse effect of morphine that should be reported immediately. While a heart rate of 88/min, pain rating of 4, and a temperature of 37.2°C (99°F) are within normal ranges and do not indicate immediate concern related to morphine administration.

Correct Answer: B

Rationale: Placing a pillow between the client's legs when turning is essential to prevent hip dislocation post hip replacement surgery. This action helps maintain proper alignment of the hip joint and prevents adduction, which can lead to dislocation. Positioning the client's legs in adduction (choice A) can increase the risk of hip dislocation. Keeping the client in a low Fowler's position (choice C) or turning the client onto the affected side (choice D) does not directly address hip dislocation prevention.

Correct Answer: C

Rationale: The correct answer is C: Sodium 140 mEq/L. An elevated sodium level can affect the effectiveness of digoxin therapy and may lead to toxicity. Therefore, it is crucial to report this value to the provider. Potassium, calcium, and magnesium levels are important as well, but elevated sodium can have a more direct impact on digoxin therapy in this scenario.

Correct Answer: B

Rationale: The correct answer is B. Clients taking metoprolol should regularly check their pulse and should not take the medication if their pulse is too low. Option A is incorrect because metoprolol should not be taken with a glass of milk. Option C is incorrect because stopping medication abruptly can be harmful. Option D is incorrect because antacids should not be taken with metoprolol as they can decrease its absorption.
