Correct Answer: C

Rationale: A key principle of patient teaching that ensures patient safety is the confirmation of understanding. To ensure patient safety, it is crucial to confirm that the patient comprehends the information provided. This confirmation can be achieved by having the patient repeat back the information or demonstrate understanding through return demonstration. Documenting the patient's understanding is essential to track the effectiveness of the teaching session and ensure that the patient is equipped with the necessary knowledge for their safety. Family members being present or having multiple staff members provide teaching may be beneficial in certain situations, but the primary focus should be on confirming the patient's understanding to enhance safety and promote effective learning.

Correct Answer: C

Rationale: Validation is the process of confirming that data are actual and factual. Data that can be measured can be accepted as factual, as in options 1, 3, and 4. The weight, blood pressure, and physical appearance of a lesion can be objectively verified. However, option C, the client reporting an infected toe, requires the nurse to directly assess the client's toe to confirm the statement. This choice involves subjective data that needs to be validated through direct observation, making it the correct answer. Options A, B, and D provide data that can be measured objectively and verified without the need for further assessment.

Correct Answer: D

Rationale: The most objective response in this situation is to explain to the family member that there is a specific reason for dimming the lights and offer to share a research study to provide evidence-based information. By doing so, it helps the family member understand that the care provided is based on established practices and research, potentially alleviating her concerns and ensuring that her husband receives appropriate care. Choices A, B, and C do not address the family member's concern or provide a rationale backed by evidence, making them less suitable responses in this context.

Correct Answer: B

Rationale: Self-disclosure is a therapeutic communication technique that nurses use to build rapport and trust with clients. By sharing personal experiences, nurses can help clients feel understood and encourage them to open up. In this scenario, the nurse sharing her own struggle with visiting her mother demonstrates self-disclosure. Empathy (choice A) involves understanding and sharing the feelings of another, but in this case, the nurse is sharing her own experience rather than focusing solely on the client's emotions. Disapproval (choice C) and false reassurance (choice D) do not apply in this context as the nurse is not expressing disapproval or giving false hope or comfort.

Correct Answer: C

Rationale: The correct answer is C. When a client is receiving a monoamine oxidase inhibitor (MAOI), they should avoid foods high in tyramine to prevent a hypertensive crisis. Cheese, beer, and products with chocolate are rich in tyramine and can interact with MAOIs, leading to a dangerous rise in blood pressure. Choices A, B, and D do not contain high levels of tyramine and are not typically restricted when taking MAOIs.
