After the surgical incision has been clised and the anesthesia has wear-off, the patient is extubated and transferred to the postanesthesia care unit (PACU). Who is responsible for transferring the patient?

Correct Answer: D

Rationale: The anesthesiologist is responsible for transferring the patient to the postanesthesia care unit (PACU) after the surgical incision has been closed and the anesthesia has worn off. The anesthesiologist ensures that the patient is stable and ready for transfer, including assessing vital signs and overall condition. Due to their specialized training in anesthesia and perioperative care, the anesthesiologist is best equipped to manage the transition of care from the operating room to the PACU, where the patient will continue to be monitored closely during the immediate postoperative period.

Correct Answer: B

Rationale: For an agitated head-injured patient, the most therapeutic setting would be a semiprivate room with one or two consistent caregivers. Consistency and familiarity can help reduce agitation and promote a sense of security for the patient. A quieter environment with fewer stimuli can also help in managing agitation and promoting a sense of calmness. By having consistent caregivers, the patient can build trust and feel more comfortable, which can contribute to their overall well-being and recovery. It is essential to minimize external factors that could contribute to further agitation, making a semiprivate room with consistent caregivers the most optimal setting for an agitated head-injured patient.

Correct Answer: C

Rationale: Lumbar pain during a blood transfusion can be a sign of an adverse reaction, such as a transfusion reaction. Any complaints of pain during a transfusion should not be ignored. In this case, the nurse should first stop the transfusion to prevent any further complications. The client should be assessed promptly for other signs of a transfusion reaction, and appropriate actions should be taken as needed to ensure the client's safety and well-being.

Correct Answer: A

Rationale: The cause of death of most AIDS patients who develop multiple opportunistic infections can be attributed to a combination of factors.

Correct Answer: C

Rationale: In septic shock, vasoconstriction is a common phenomenon. This occurs as part of the body's response to the infection, where blood vessels constrict in an attempt to maintain blood pressure and perfusion to vital organs. The vasoconstriction leads to increased systemic vascular resistance and contributes to the hypotension seen in septic shock. The body's natural response to infection also involves a release of inflammatory mediators, which can cause vasodilation in some areas while concurrent vasoconstriction occurs in others, resulting in uneven blood flow distribution and contributing to organ dysfunction. Therefore, vasoconstriction is a key factor in the pathophysiology of septic shock.
