Correct Answer: A

Rationale: The correct answer is A: fluid retention of 1.5 liters. The weight gain from 97.5 kg to 99 kg indicates an increase in fluid retention. This difference of 1.5 kg corresponds to fluid retention of 1.5 liters, as 1 liter of water weighs approximately 1 kg. This weight gain suggests that the patient is retaining more fluid than they are excreting, leading to an increase in weight. Incorrect choices: B: fluid loss of 1.5 liters - This is incorrect because the weight increased, indicating fluid retention. C: equal intake and output due to insensible losses - This is incorrect as weight increased, showing an imbalance in intake and output. D: fluid loss of 0.5 liters - This is incorrect as the weight increased, indicating fluid retention, not loss.

Correct Answer: A

Rationale: Rationale: Accurately identifying patients is a National Patient Safety Goal to prevent errors in patient care. Proper patient identification ensures correct treatments and medications are given, reducing harm. Restraint elimination, medication reconciliation, and infection reduction are important goals but not specific National Patient Safety Goals. Accurate patient identification directly addresses patient safety concerns.

Correct Answer: C

Rationale: The correct answer is C: A woman who originally escorted the patient in. This choice is correct because she is most likely the person responsible for the patient's care and thus likely has legal authority to make medical decisions on behalf of the patient. The other choices are incorrect because simply being recognized as the patient's brother (A), being a teenage boy who approaches the nurse (B), or being a woman whom the others look at and call over (D) does not necessarily indicate that they have the legal authority to make medical decisions for the unconscious patient.

Correct Answer: A

Rationale: The correct answer is A: "Do you feel safe in your home?" This question is most appropriate because it directly addresses the potential issue of elder abuse without assuming or accusing the patient. It allows the patient to disclose any safety concerns and initiates a conversation about their well-being. Options B and D are inappropriate as they are accusatory and may escalate the situation. Option C is not as direct and may not effectively address the safety concerns of the patient.

Correct Answer: A

Rationale: The correct answer is A because this patient had a complex surgery with complications, requiring long-term care and loss of a significant other, which can impact their emotional well-being and support system. This can lead to decreased functional status and quality of life. Choice B is incorrect as the patient has support from a spouse and manages health care independently, indicating a good support system. Choice C is incorrect as the patient is cognitively intact and social, which suggests a good quality of life. Choice D is incorrect as the patient had a less complex procedure, well-managed diabetes, and was living independently, which indicates a lower risk for decreased functional status and quality of life compared to choice A.
