Correct Answer: D

Rationale: The correct answer is D: anesthesiologist. The anesthesiologist is responsible for transferring the patient to the PACU as they are in charge of the patient's anesthesia management throughout the surgery. They are trained to assess the patient's condition post-surgery, manage any immediate postoperative complications, and ensure a smooth transition to the PACU staff for continued care. The circulating nurse (A) is responsible for managing the operating room environment, the scrub nurse (B) assists the surgeon during the surgery by passing instruments, and the surgeon (C) performs the surgical procedure but does not typically transfer the patient to the PACU.

Correct Answer: C

Rationale: The correct answer is C: Hypoventilation. In chronic respiratory acidosis, the lungs cannot effectively eliminate carbon dioxide, leading to an accumulation of CO2 in the blood, causing acidosis. Hypoventilation results in decreased removal of CO2, exacerbating the acidosis. A: Hyperventilation would lead to respiratory alkalosis, not acidosis. B: Loss of acid by kidneys would result in metabolic alkalosis, not respiratory acidosis. D: Loss of base by kidneys would lead to metabolic acidosis, not respiratory acidosis. In summary, the main issue in chronic respiratory acidosis is inadequate elimination of CO2 due to hypoventilation, leading to acidosis.

Correct Answer: A

Rationale: Step 1: Involving the client in planning increases their understanding and ownership of the plan. Step 2: Understanding leads to better compliance with therapy recommendations. Step 3: Compliance improves outcomes and prevents complications. Step 4: Thus, choice A is correct. Choices B, C, and D lack direct links to client involvement in planning and compliance.

Correct Answer: D

Rationale: The correct answer is D, Arcus senilis. This condition does not cause visual problems in the older adult. Arcus senilis is a grayish-white ring around the cornea, which does not affect vision. Glaucoma, macular degeneration, and cataracts are conditions that can lead to visual impairment in older adults. Glaucoma is characterized by increased pressure in the eye, which can damage the optic nerve and lead to vision loss. Macular degeneration affects the central part of the retina, leading to blurred or distorted vision. Cataracts cause clouding of the lens, resulting in decreased vision. Therefore, Arcus senilis is the correct choice as it does not cause visual problems compared to the other conditions listed.

Correct Answer: C

Rationale: The correct answer is C: Night sweats. In Hodgkin's disease category B, the presence of night sweats signifies more advanced disease and higher tumor burden. Night sweats are a B-symptom, along with fever and weight loss, indicating systemic symptoms. Anemia (choice B) and thrombocytopenia (choice D) are not specific to Hodgkin's disease category B and can be present in various other conditions. Fever (choice A) is not exclusive to Hodgkin's disease category B and can occur in many infections and inflammatory conditions. Night sweats are specifically associated with Hodgkin's disease and are a key indicator of disease severity in this context.
