After the nurse has finished teaching a patient who has a new prescription for exenatide (Byetta), which patient statement indicates that the teaching has been effective?

Correct Answer: C

Rationale: The correct answer is C. This statement indicates effective teaching because taking aspirin at least an hour before exenatide (Byetta) helps prevent any potential interactions between the two medications. By understanding the importance of timing, the patient shows comprehension of medication management and potential risks. Incorrect choices: A: This choice is incorrect because exenatide is known to reduce appetite, not increase hunger. B: This choice is incorrect because hypoglycemia is still a risk with exenatide, especially if used with other medications that lower blood sugar. D: This choice is incorrect because exenatide is injected, not taken as a pill, and should be taken before meals, not with breakfast.

Correct Answer: D

Rationale: The correct answer is D: Abdominal cramping. A sodium level of 125 mEq/L indicates hyponatremia, which can lead to abdominal cramping due to electrolyte imbalance affecting muscle function. Chvostek's sign (choice A) is associated with hypocalcemia, not hyponatremia. Bradycardia (choice B) is more commonly seen in hyperkalemia. Numbness of the extremities (choice C) is a symptom of hypocalcemia or peripheral neuropathy, not specifically related to hyponatremia. In summary, the healthcare professional should expect abdominal cramping as a result of the low sodium level in this client.

Correct Answer: C

Rationale: The correct answer is C: Assist the client to an upright position. This is the priority intervention because placing the client in an upright position helps improve lung expansion and oxygenation by optimizing ventilation-perfusion matching. This position also reduces the risk of aspiration and improves overall respiratory function. Choice A (Suction the client's airway) is not the first intervention because difficulty breathing in this scenario is more likely due to positioning rather than airway obstruction. Choice B (Instruct the client to perform incentive spirometry every hour) is not the first intervention as it may not address the immediate issue of breathing difficulty related to supine positioning. Choice D (Humidify the client's supplemental oxygen) is not the first intervention as lack of humidification is not likely the cause of the client's difficulty breathing in this situation.

Correct Answer: C

Rationale: The correct answer is C because the client's statement demonstrates a desire for comfort-focused care, which is the essence of palliative care for terminal cancer patients. The client is expressing a clear preference for measures that prioritize comfort and quality of life over aggressive treatment. This indicates readiness to receive information about palliative care. Choice A is incorrect because the client mentions chemotherapy for a cure, indicating a focus on curative treatment rather than comfort care. Choice B is incorrect as the client seems to be expressing a desire for a quick end to their suffering, which may not align with palliative care goals. Choice D is incorrect because the client is expressing unrealistic optimism about recovery, which may hinder acceptance of palliative care.

Correct Answer: A

Rationale: The correct answer is A: Wear an N95 respirator when giving direct care to the client. This is correct because allogeneic stem cell transplant recipients are at high risk for infection due to immunosuppression. An N95 respirator helps protect the nurse from inhaling airborne pathogens when in close contact with the client. Choice B is incorrect because negative-pressure airflow rooms are typically used for clients with airborne infections, not for those at risk due to immunosuppression. Choice C is incorrect because although adequate air exchanges are important for infection control, it is not the specific precaution needed for a client with an allogeneic stem cell transplant. Choice D is incorrect because wearing a mask outside the room is not as effective in preventing transmission of infections as wearing an N95 respirator during direct care.
