Correct Answer: A

Rationale: The correct answer is to instruct the client to increase potassium-rich foods in the diet. Furosemide is a loop diuretic that can cause potassium loss as a side effect. By increasing potassium-rich foods, the client can help prevent hypokalemia, a potential complication of furosemide therapy. Choice B is incorrect because while limiting sodium intake is generally advisable for heart failure, it is not directly related to furosemide use. Choice C is incorrect because fluid intake should be monitored and adjusted based on the individual's condition, but setting a specific limit of 1 liter per day is not a standard recommendation. Choice D is incorrect because furosemide is usually taken in the morning to prevent disturbances in sleep due to increased urination during the night.

Correct Answer: C

Rationale: Observing the UAP's ability to implement precautions during feeding is crucial to ensuring the client's safety, especially when there is a risk of aspiration. This hands-on observation allows the nurse to assess whether the UAP is competent in handling the feeding procedure safely. Informing the UAP about suction availability (Choice A) is important but does not directly assess the UAP's ability during feeding. Instructing the UAP to notify the nurse if the client chokes (Choice B) focuses on reactive measures rather than proactive supervision. Asking about previous experience (Choice D) does not provide real-time information on the UAP's current competency in handling the specific feeding task for the at-risk client.

Correct Answer: D

Rationale: The correct answer is D, prolonged PT/INR. In a client with chronic liver disease, a prolonged PT/INR is the most concerning lab value. This indicates impaired liver function, leading to a higher risk of bleeding. Elevated AST and ALT (choice A) are indicators of liver damage but do not directly assess the risk of bleeding. Decreased albumin level (choice B) reflects impaired liver function but is not as directly related to bleeding risk as a prolonged PT/INR. Elevated bilirubin level (choice C) is a sign of liver dysfunction, specifically related to bile metabolism, and while important, it is not as directly associated with bleeding risk as a prolonged PT/INR in the context of chronic liver disease.

Correct Answer: A

Rationale: When caring for a client receiving palliative care for terminal cancer, the nurse should prioritize pain management. Effective pain management is crucial in enhancing the quality of life for terminally ill patients. While arranging family visits and discussing advance directives are important aspects of care, pain management takes precedence in providing comfort and alleviating suffering. Nutritional support is essential but may be of lesser priority compared to pain management in this context.

Correct Answer: B

Rationale: In the case of diabetic ketoacidosis, the most critical treatment to initiate is starting an insulin drip. Insulin therapy is crucial for reducing blood glucose levels by promoting glucose uptake in cells and inhibiting the production of ketones. Administering sodium bicarbonate IV is generally not recommended as it may lower the pH further and potentially worsen the condition. While monitoring glucose and ketone levels is important for assessing the response to treatment, initiating insulin therapy takes precedence. Providing oral hydration alone is insufficient to manage the metabolic derangements seen in diabetic ketoacidosis.
