Correct Answer: A

Rationale: The correct answer is A: Liver toxicity. Methotrexate is known to cause liver toxicity, making regular monitoring of liver function essential. Monitoring liver function tests helps detect any signs of liver damage early, allowing for appropriate interventions to be implemented promptly.

Correct Answer: A

Rationale: The correct answer is A: Drowsiness. Alprazolam, a medication commonly used to treat anxiety disorders, can cause drowsiness as a common side effect. Clients should be advised not to drive or operate heavy machinery until they know how the medication affects them to ensure their safety.

Correct Answer: A

Rationale: Enoxaparin is an anticoagulant that works by preventing blood clots. One of the potential adverse effects of enoxaparin is an increased risk of bleeding due to its anticoagulant properties. Therefore, the nurse should monitor the client for signs of bleeding, such as easy bruising, petechiae, or blood in stool or urine, to ensure timely intervention and prevent complications.

Correct Answer: A

Rationale: The correct answer is A: Dry cough. Lisinopril, an ACE inhibitor, is known to cause a persistent dry cough as a common side effect. Monitoring for this adverse effect is crucial because it may lead to non-adherence to the medication. Hyperkalemia (choice B) is a potential side effect of potassium-sparing diuretics, not ACE inhibitors like lisinopril. Hypernatremia (choice C) refers to elevated sodium levels and is not a common side effect of lisinopril. Hyponatremia (choice D) is a condition characterized by low sodium levels and is not a typical side effect of lisinopril. Therefore, the nurse should focus on assessing the client for a dry cough when taking lisinopril.

Correct Answer: C

Rationale: Correct Answer: The most important instruction for a client taking methotrexate is to report any signs of infection immediately. Methotrexate can suppress the immune system, making the client more susceptible to infections. Early detection and treatment of infections are crucial to prevent complications. Instructing the client to be vigilant for signs of infection empowers them to take prompt action, enhancing their overall safety and well-being.
