Correct Answer: B

Rationale: Providing research-based information about the benefits of therapeutic hypothermia for their loved one will provide evidence that this is an established therapy with generally positive outcomes. Families are certainly not expected to be familiar with critical care interventions, and their concerns should be addressed with evidence-based data whenever possible. Option A is not appropriate as sharing patient information violates privacy laws and does not address the family's concerns directly. Option C may not directly provide the detailed information the family needs to understand therapeutic hypothermia. Option D involves unnecessary escalation by immediately involving the physician, when providing education and information should be the initial step in addressing the family's concerns.

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: D

Rationale: Forming a peer workgroup to evaluate new products would be an excellent opportunity for collaboration among peers, management, and the purchasing department. When clinicians are engaged to work toward solutions that address patient care issues, they experience more empowerment and control over their work environments. Choice A is incorrect because using old stock from a previous company does not address the root cause of the faulty transducers from the current company. Choice B is incorrect as verifying cuff pressures every hour does not directly address the issue of faulty transducers. Choice C is less effective than forming a peer workgroup as it involves only notifying the risk manager without involving a collaborative effort to resolve the product issue.

Correct Answer: B

Rationale: Teaching both the patient's wife and the daughter is the best option in this situation. The daughter may not always be available, and the wife is eager to care for her husband at home. While a hospital interpreter is often preferred, asking the daughter to interpret is a good alternative. This approach allows the daughter to receive instruction and reinforce it for herself as she translates it to her mother. Contacting a home health agency may not be necessary if family members are willing and able to assist. Providing a pamphlet with detailed instructions would not be as effective in ensuring the wife fully understands the procedure and can carry it out correctly.

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.
