Correct Answer: A

Rationale: The correct action the nurse should include in the plan of care is to keep the client NPO until the pharyngeal response returns. This is important to prevent aspiration until the client's normal pharyngeal sensation is restored, typically within about 1 hour after the procedure. Monitoring the insertion site for a hematoma, palpating the bladder, and maintaining the client on bed rest are not directly related to the administration of Tetracaine prior to a Bronchoscopy.

Correct Answer: B

Rationale: Ciprofloxacin should not be taken with dairy products because calcium can interfere with the absorption of the medication. The client should be instructed to take it 1 hour before or 2 hours after consuming dairy products to ensure optimal effectiveness of the medication.

Correct Answer: B

Rationale: When administering enoxaparin, it is essential to insert the needle completely into the client's tissue to ensure a deep subcutaneous injection. This method helps in the appropriate delivery of the medication.

Correct Answer: C

Rationale: The correct answer is C because Warfarin interacts with vitamin K, found in green leafy vegetables, not potassium. The client should avoid consuming large amounts of foods high in vitamin K to maintain the effectiveness of Warfarin therapy. Increasing potassium intake is not a concern related to Warfarin therapy, so this statement indicates a need for further teaching.

Correct Answer: D

Rationale: Metoprolol, a beta-adrenergic blocker, is commonly used to treat hypertension and stable angina pectoris. It is often prescribed to decrease heart rate in clients who develop tachycardia, such as in the case of reflex tachycardia induced by Isosorbide Mononitrate, making it the appropriate choice in this scenario.
