1. What lab value should a healthcare provider monitor for a patient on warfarin therapy?

Correct answer: B

Rationale: The correct answer is B: PT/INR. When a patient is on warfarin therapy, healthcare providers monitor the PT/INR levels to evaluate the effectiveness of the treatment and assess the risk of bleeding. Monitoring potassium, sodium, or calcium levels is not directly related to warfarin therapy and would not provide the necessary information needed to manage the medication effectively.

2. What is the most appropriate nursing intervention for a patient experiencing hypoglycemia?

Correct answer: B

Rationale: The most appropriate nursing intervention for a patient experiencing hypoglycemia is to administer oral glucose. Oral glucose is usually sufficient for treating mild hypoglycemia and can be administered quickly and easily. Administering IV glucose (Choice A) is reserved for severe cases where the patient is unable to swallow or unconscious. Checking blood sugar in 15 minutes (Choice C) is important but providing glucose should come first. Providing a high-calorie snack (Choice D) may not be as rapidly effective as administering oral glucose in quickly raising blood sugar levels in a patient experiencing hypoglycemia.

3. A nurse is caring for a client who has cirrhosis and a new prescription for lactulose. The nurse should monitor the client for which of the following therapeutic effects of this medication?

Correct answer: C

Rationale: The correct answer is C: Decreased serum ammonia. Lactulose is prescribed to decrease serum ammonia levels in clients with cirrhosis and hepatic encephalopathy. By reducing serum ammonia, lactulose helps improve the mental status of these clients. Therefore, monitoring for decreased serum ammonia is crucial to assess the effectiveness of lactulose therapy. Choice A (Improved mental status) is indirectly related as it is the desired outcome of decreasing ammonia levels. Choices B (Increased urine output) and D (Decreased bilirubin levels) are not directly associated with the therapeutic effects of lactulose in cirrhosis and hepatic encephalopathy.

4. A nurse is caring for a client who has a pressure ulcer. Which of the following findings should the nurse report to the provider?

Correct answer: D

Rationale: The correct answer is D, 'Undermining.' Undermining occurs when the tissue under the wound edges erodes, indicating poor healing progress. This finding should be reported to the provider as it suggests delayed wound healing and may require intervention. Choice A, 'Eschar,' is a thick, hard, black/brown necrotic tissue that forms over a wound. While it indicates a non-healing wound, it is not as concerning as undermining. Choice B, 'Slough,' is a soft, moist, yellow/white tissue that is also a sign of necrosis. While the presence of slough indicates the need for wound cleaning and debridement, it is not as critical to report as undermining. Choice C, 'Granulation tissue,' is new tissue that forms during wound healing and is a positive sign. The presence of granulation tissue indicates that the wound is progressing through the healing stages and is not a finding that requires immediate reporting to the provider.

5. When discussing clients designating a health care proxy in situations requiring a durable power of attorney for health care (DPAHC), what information should the charge nurse include?

Correct answer: C

Rationale: The correct answer is C. The charge nurse should include information that the proxy can make treatment decisions if the client is under anesthesia. This is a key function of a durable power of attorney for health care. Choices A, B, and D are incorrect because a health care proxy's role is specifically related to making health care decisions, not financial decisions, legal issues, or decisions made under anesthesia.
