Correct Answer: A

Rationale: The correct answer is A. Metronidazole (Flagyl) can cause a disulfiram-like reaction when taken with alcohol, resulting in severe nausea, vomiting, and headache. Therefore, the client should be advised to avoid alcohol while taking this medication to prevent adverse effects. Avoiding alcohol is crucial to prevent these reactions and ensure the effectiveness of the treatment. The other options are not directly related to the specific medication or the condition being treated.

Correct Answer: B

Rationale: The correct action for the nurse to take in this situation is to contact the registered nurse. When a client with coronary artery disease experiences chest pain and does not achieve relief after the initial administration of nitroglycerin, it is crucial to inform the registered nurse promptly. Following the usual guideline for nitroglycerin administration, the nurse may administer a second tablet after assessing the client's pain level. The nurse should continue to assess the client's pain and monitor vital signs before each dose administration. Calling a code blue is not warranted at this point, as the client's condition does not indicate an immediate life-threatening emergency. Contacting the client's family is not necessary unless requested by the client.

Correct Answer: A

Rationale: When ciprofloxacin (Cipro) is given with warfarin sodium (Coumadin), it can potentiate the effects of warfarin, leading to an increased risk of bleeding. Therefore, the nurse should closely monitor the client's INR levels and watch for signs of bleeding such as bruising, petechiae, or black tarry stools.

Correct Answer: D

Rationale: Morphine sulfate suppresses the cough reflex, which can lead to the retention of secretions in the lungs. Encouraging the client to cough and deep breathe helps prevent pneumonia by clearing the airways of any accumulated secretions. This intervention is crucial in clients receiving morphine sulfate to maintain optimal respiratory function.
