Correct Answer: A

Rationale: The correct answer is A: Pitting edema of bilateral lower extremities. Pitting edema can indicate fluid overload, which is a potential complication of TPN administration. Choice B, hypoactive bowel sounds, is more indicative of a gastrointestinal issue rather than a complication of TPN. Choice C, weight remaining the same, is expected to remain stable with proper TPN administration. Choice D, diminished lung sounds, is not directly related to TPN administration and is more suggestive of a respiratory issue.

Correct Answer: C

Rationale: The correct answer is C because a CPAP device delivers a preset amount of positive airway pressure continuously throughout all inspiration and expiration cycles. Choice A is incorrect because CPAP does not deliver inspiratory pressure at the beginning of each breath; it provides continuous positive pressure. Choice B is incorrect because CPAP typically delivers a constant pressure rather than having a feature that changes pressure throughout the cycle. Choice D is incorrect as CPAP does not deliver positive pressure specifically at the end of each breath; it maintains a consistent pressure throughout the breathing cycle.

Correct Answer: C

Rationale: The correct answer is C: Atropine. The client's presentation of bradycardia, diaphoresis, and chest pain indicates reduced cardiac output, requiring intervention to increase the heart rate. Atropine is used to treat bradycardia by blocking cardiac muscarinic receptors, thus inhibiting the parasympathetic nervous system. Lidocaine (Choice A) is used for ventricular arrhythmias, not bradycardia. Adenosine (Choice B) is used for supraventricular tachycardia, not bradycardia. Verapamil (Choice D) is a calcium channel blocker used for certain arrhythmias and hypertension, but not for increasing heart rate in bradycardia.

Correct Answer: D

Rationale: The nurse should encourage the client to attend a support group for individuals who have burn injuries. Support groups can provide emotional support, shared experiences, and coping strategies for accepting their altered appearance. Choice A is not the best response as it does not offer proactive support. Choice B is not appropriate as the timing of cosmetic surgery should be determined by healthcare providers, not immediate. Choice C is misleading as reconstructive surgery may improve appearance but may not completely restore the previous look.

Correct Answer: D

Rationale: The correct first action for the nurse to take when suspecting an adverse reaction to a blood transfusion is to stop the transfusion immediately. Stopping the transfusion helps prevent further harm to the client. Maintaining IV access and obtaining vital signs are important steps but come after stopping the transfusion in this situation. Contacting the provider can be done after ensuring the client's safety by stopping the transfusion.
