Correct Answer: B

Rationale: Wear sterile gloves and break off the neck of the glass ampule with a single snap to the right side: While wearing sterile gloves is recommended, breaking the ampule to the right side is not a standard or safe practice. The ampule should be broken in a forward motion, away from the body.Tap the bottom of the ampoule, place a gauze pad around the ampule neck, and break off the bottom with a forward motion away from the body: This is the correct technique for opening a glass ampule. Tapping the bottom ensures that the liquid is settled away from the neck, and using a gauze pad around the neck provides protection from glass shards. The ampule should be broken away from the body to prevent injury.Wear sterile gloves and break off the neck of the glass ampule with a single snap in a downward motion: Breaking the ampule in a downward motion is not the recommended technique, as it could cause injury or spill the medication. The correct method is to break it away from the body in a forward motion.Tap the top of the ampule, place a sterile gauze pad around the ampule neck, and break off the top by bending it toward the body: Tapping the top is incorrect, as it could cause the medication to spill. The correct technique is to tap the bottom of the ampule. Additionally, the ampule should be broken away from the body, not toward it.

Correct Answer: B

Rationale: Tell the client the physician wants him to take the medications: This response does not address the client’s concerns or autonomy. It is important to respect the client’s right to make decisions about their care, and simply telling them what the physician wants does not foster an open dialogue.Ask the client why he is refusing to take the medications: This is the most appropriate action. The nurse should assess the reason for the client's refusal to better understand the underlying concerns or misconceptions. This can help the nurse address any fears, misunderstandings, or barriers to medication adherence.Explain the purpose for the medications: While this is a good action, it is more effective after understanding why the client is refusing. Simply explaining the medication may not resolve the client's concerns if they have specific reasons for refusal.Document that the client refuses the medications: Documentation is important but should not be the first step. The nurse should first try to understand the client’s reasons for refusal and address them before documenting.
