Critical Care Nursing Practice Questions

Correct Answer: A

Rationale: The correct answer is A because it respects the patient's right to privacy while also acknowledging the family's presence. By asking family members if they wish to remain in the room, the nurse allows them to make an informed decision based on their comfort level. This approach fosters open communication and shows respect for the family's emotions. Choice B is incorrect because abruptly removing family members can increase their distress and feelings of powerlessness. Choice C is incorrect as it places the burden of support solely on a staff member, potentially isolating the family from the situation. Choice D is incorrect as it assumes family members should stay without considering their preferences or emotional well-being.

Correct Answer: B

Rationale: The correct answer is B: Partly compensated respiratory acidosis, normal oxygen. The pH of 7.31 indicates acidosis, the PaCO2 of 48 mm Hg shows respiratory acidosis, and the bicarbonate level of 22 mEq/L is slightly elevated, indicating the kidneys are compensating. The PaO2 of 115 mm Hg and oxygen saturation of 99% are normal, ruling out hypoxemia. Therefore, the patient is experiencing partly compensated respiratory acidosis. A: Normal arterial blood gas levels with a high oxygen level - Incorrect. The pH is low, indicating acidosis, which is not normal. C: Uncompensated metabolic acidosis with high oxygen level - Incorrect. Metabolic acidosis would have a primary issue with bicarbonate levels, which is not the case here. D: Uncompensated respiratory acidosis; hyperoxygenated - Incorrect. The oxygen levels are normal, ruling out hyperoxygenation.

Correct Answer: D

Rationale: The correct answer is D: Sense of loss of control of the situation. The wife's demand to reassign the nurse indicates her need for control over her husband's care, as she may feel overwhelmed by the sudden cardiac arrest and hospitalization. By requesting a different nurse, she seeks to regain a sense of control and assurance. The other choices are incorrect because: A does not align with the wife's immediate concern, B does not explain her request for a nurse reassignment, and C does not address her emotional response to the situation.

Correct Answer: C

Rationale: The correct answer is C because it involves patient-centered care and respects the family's preferences. By asking the family members whether they would prefer to remain in the patient's room or wait outside, the nurse acknowledges their needs and allows them to make an informed decision based on their comfort level. This empowers the family members and promotes a supportive environment during a stressful situation. Choice A is incorrect because it assumes that keeping the family in the room without their input is the best approach, which may not be the case for all families. Choice B is incorrect because asking the family to wait outside without considering their preferences may not be the most supportive action. Choice D is incorrect because it makes a blanket statement about patient comfort without considering individual family dynamics and preferences.

Correct Answer: C

Rationale: The correct answer is C: Notify the organ procurement organization (OPO). This is the best action because the OPO is responsible for coordinating organ donation and transplantation. By involving the OPO, the nurse ensures that the donation process is handled appropriately and ethically. Choice A: Arranging a multidisciplinary meeting with physicians may be necessary but should not be the first step in this situation. Choice B: Consulting the hospital�s ethics committee may be helpful, but the immediate priority is to involve the OPO to facilitate organ donation. Choice D: Obtaining family consent to withdraw life support is not the nurse�s role in this situation. The focus should be on organ donation to honor the family's wishes.
