Correct Answer: A

Rationale: Rationale for Correct Answer A: Donor disfigurement influences on funeral care. Families often consider the impact of organ donation on the appearance of their loved one during funeral arrangements. This concern can significantly influence their decision to donate. Incorrect Answers: B: Fear of inferior medical care provided to donor. This is not a common concern as medical care for donors is typically of high quality. C: Age and location of all possible organ recipients. While important, this is not a primary concern for families when deciding on organ donation. D: Concern that donated organs will not be used. Families are generally more concerned about the impact on their loved one's appearance post-donation rather than the utilization of organs.

Correct Answer: D

Rationale: The correct answer is D because positive end-expiratory pressure (PEEP) is a mode of ventilation where pressure is maintained in the lungs at the end of expiration. This helps prevent alveolar collapse and improves oxygenation. Option A is incorrect because PEEP does not deliver a full preset tidal volume with each breath initiation. Option B is incorrect because tidal volume in PEEP is not solely determined by the patient's ability to generate negative pressure. Option C is incorrect because in PEEP, breaths are delivered irrespective of the patient's respiratory drive.

Correct Answer: B

Rationale: The correct answer is B because it acknowledges and validates the patient's belief, showing empathy and support. By stating that the belief gives strength, the nurse facilitates a therapeutic relationship and promotes the patient's emotional well-being. Choice A is incorrect as it challenges the patient's belief system, potentially creating conflict. Choice C is inappropriate as it dismisses the patient's belief and could damage the nurse-patient relationship. Choice D is also incorrect as it invalidates the patient's belief and could harm trust and rapport.

Correct Answer: C

Rationale: The correct answer is C: Volume overload. In acute kidney injury, impaired kidney function leads to fluid retention, causing volume overload. Dialysis helps remove excess fluid to restore fluid balance. Acidosis and hyperkalemia are potential complications of acute kidney injury but not the primary reasons for initiating dialysis. Hypokalemia is unlikely in acute kidney injury due to impaired excretion of potassium by the kidneys. Therefore, the most common reason for initiating dialysis in acute kidney injury is to manage volume overload.

Correct Answer: A

Rationale: The correct answer is A because a cooler right hand may indicate compromised circulation, potentially due to arterial occlusion or clot formation. This could lead to inadequate perfusion and tissue damage. Immediate action is needed to assess and address the cause. Choice B is incorrect because a MAP of 77 mm Hg is within the normal range for most patients and does not require immediate action. Choice C is incorrect as delivering 3 mL of flush solution per hour is an appropriate rate and does not indicate a need for immediate action. Choice D is incorrect as the flush bag and tubing being changed 3 days ago does not necessarily indicate an immediate issue with the arterial line function.
