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: A

Rationale: The expected date of delivery is calculated using Nagle's rule which is: The first day of last menstrual period - 3 months + 7 days = the estimated date of delivery

Correct Answer: C

Rationale: The correct medication to address the symptom described, where the client is slow to respond and appears to be listening to unseen others, is Risperidone (Risperdal). Risperidone is an atypical antipsychotic that is commonly used to manage positive symptoms of schizophrenia. Positive symptoms can include hallucinations, delusions, and disorganized thinking. Haloperidol (Haldol) and Clozapine (Clozaril) are typically used for addressing negative symptoms, such as lack of motivation or social withdrawal. Clonazepam (Klonopin) is a benzodiazepine primarily used for anxiety disorders and seizures, not for addressing symptoms of schizophrenia.

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: A

Rationale: For a manic client who is hyperactive and may engage in injurious activities, setting realistic limits to the client's behavior is crucial to ensure safety. A quiet environment with firm and consistent limits helps in managing the client's behavior effectively. While repeating verbal instructions can be helpful due to the client's distractibility, it is not the priority compared to setting limits for safety concerns. Allowing the client to express feelings is important, but it should be done through non-destructive methods. Assigning staff to be with the client at all times is not realistic or feasible in the clinical setting and does not address the core issue of managing the client's behavior and ensuring safety.
