1. A practical nurse (PN) is preparing to administer a scheduled dose of furosemide to a client. Which laboratory value is most important for the PN to review before administering the medication?

Correct answer: B

Rationale: The correct answer is to review the client's serum potassium level before administering furosemide. Furosemide, a loop diuretic, can lead to hypokalemia, making it crucial to assess potassium levels to prevent potential complications like cardiac arrhythmias associated with low potassium levels.

2. A client is receiving heparin to treat a deep vein thrombosis. The nurse should monitor which laboratory result to assist in evaluating the efficacy of the drug?

Correct answer: C

Rationale: The nurse should monitor the partial thromboplastin time to evaluate the efficacy of heparin. Partial thromboplastin time reflects the anticoagulant effect of heparin by measuring the intrinsic pathway of coagulation. Platelet count assesses platelet levels and is not specific to heparin efficacy. Prothrombin time is used to monitor warfarin therapy. Serum levels of protamine sulfate are not used to evaluate the efficacy of heparin.

3. During a home visit, a client with a history of angina reports frequent headaches. The client recently started a new prescription for diltiazem, a calcium channel blocker. What action should the nurse take?

Correct answer: D

Rationale: The correct action for the nurse to take is to instruct the client to use acetaminophen for headaches. Acetaminophen is a suitable and safer option for managing headaches associated with calcium channel blockers like diltiazem. It is essential to avoid medications that can interact negatively with diltiazem, such as opioid analgesics. Discontinuing the medication abruptly without consulting the healthcare provider is not recommended. Monitoring for medication toxicity through blood samples is not typically indicated for managing headaches in this scenario.

4. A client with a diagnosis of schizophrenia is prescribed olanzapine. The nurse should monitor for which potential side effect?

Correct answer: A

Rationale: When a client with schizophrenia is prescribed olanzapine, the nurse should monitor for weight gain as a potential side effect. Olanzapine is known to cause metabolic changes that can lead to weight gain, making it crucial for the nurse to closely monitor the client's weight during treatment. This side effect is significant as it can impact the client's overall health and well-being, so early detection and intervention are essential to manage it effectively.

5. How should the healthcare provider schedule the administering of propylthiouracil (PTU)?

Correct answer: D

Rationale: Administering iodine one hour before PTU is crucial to ensure proper absorption and effectiveness of PTU. This timing helps optimize the therapeutic benefits of PTU by allowing it to be absorbed efficiently without interference from iodine, ultimately leading to better treatment outcomes for the patient. Choices A, B, and C are incorrect because offering both drugs together with a meal, giving parental dose once every 24 hours, and scheduling both medications at bedtime do not address the specific timing requirement of administering iodine before PTU for optimal absorption.
