Correct Answer: D

Rationale: Choosing option D, 'Try to help your dad enjoy this time as much as he can,' is the most appropriate response by the nurse. This response shows empathy and compassion towards the client and their family during this difficult transition. The focus on supporting the client in enjoying their remaining time reflects a holistic approach to care. Options A, B, and C are not the best responses in this situation. Option A could lead to unnecessary details that might be overwhelming for the family. Option B shifts the responsibility to the social worker without providing immediate support. Option C deflects the son's concerns to another healthcare professional when emotional support is needed.

Correct Answer: B

Rationale: The correct answer is B: Liver function tests. While a client is taking metformin, monitoring liver function tests is crucial to assess for potential hepatic side effects. Metformin is primarily eliminated by the liver, and monitoring liver function tests helps in early detection of any liver-related complications. Choices A, C, and D are incorrect. A complete blood count (CBC) is not specifically required for monitoring metformin therapy. Serum electrolytes are not directly impacted by metformin, making it less relevant for monitoring this medication. Renal function tests are important for some other diabetes medications, but in the case of metformin, liver function tests take precedence due to its hepatic metabolism.

Correct Answer: A

Rationale: The correct first action for the nurse to take in this situation is to check the IV tubing for obstruction. By doing this, the nurse can assess if there is any blockage or kink in the tubing that is impeding the flow of the IV solution. This step is crucial as it helps in identifying the reason for the inadequate infusion rate. Increasing the infusion rate (Choice B) without first checking for obstructions can lead to potential complications if there is a blockage. Administering a bolus of fluid (Choice C) may not be appropriate without addressing the cause of the decreased infusion rate. Similarly, replacing the IV catheter (Choice D) is not the initial priority unless obstruction is ruled out and other troubleshooting measures have been taken.

Correct Answer: D

Rationale: The correct answer is D, Nonmaleficence. Nonmaleficence refers to the principle of 'do no harm.' In this scenario, questioning a potentially harmful prescription for a client with advanced age and unstable status aligns with the principle of nonmaleficence, as the nurse is advocating for the client's safety and well-being. Choice A, Fidelity, refers to being faithful and keeping promises, which is not directly related to the situation described. Choice B, Autonomy, pertains to respecting a patient's right to make their own decisions, which is not the focus of the nurse questioning the prescription. Choice C, Justice, involves fairness and equal treatment, which is not the primary ethical principle at play in this situation.

Correct Answer: A

Rationale: When developing an individualized plan of care for a patient, the nurse must set goals that are specific, measurable, achievable, realistic, and time-bound (SMART). Choice A is correct as it emphasizes the importance of establishing goals that are measurable and realistic, ensuring they are attainable within a specific timeframe. Setting goals that are beyond the capabilities of the patient (Choice B) can lead to frustration and lack of progress. Using only the nurse's judgment and disregarding family desires (Choice C) may not consider important aspects of the patient's social support and preferences. Explaining that progress requires taking alignment risks (Choice D) is not a standard approach in nursing care planning and may confuse the patient or hinder trust in the nurse's decision-making.
