1. Which part of the nephron is closest to the collecting duct?

Correct answer: Distal convoluted tubule (DCT)

Rationale: The correct answer is the Distal convoluted tubule (DCT). The DCT is the part of the nephron closest to the collecting duct, where the final adjustments to electrolyte and fluid balance are made. Bowman's Capsule is located at the beginning of the nephron, where filtration of blood occurs. The Afferent Arteriole brings blood to the glomerulus for filtration. The Proximal Convoluted Tubule (PCT) is situated after the Bowman's Capsule and is not the part closest to the collecting duct.

2. Rectal temperatures are indicated in which situation?

Correct answer: B

Rationale: Rectal temperatures provide the most accurate measurement of core body temperature and are therefore indicated when accuracy is essential.

3. Is the parietal pericardium attached to the surface of the heart?

Correct answer: True

Rationale: The parietal pericardium is a tough, fibrous outer layer that is attached to the diaphragm and the sternum but not directly to the surface of the heart. It forms a sac around the heart known as the pericardial sac. Therefore, the statement that the parietal pericardium is attached to the surface of the heart is false.

4. A nurse is planning care for a client who is postoperative following a laminectomy. Which of the following interventions should the nurse include in the plan of care?

Correct answer: D

Rationale: Ambulating the client on the first postoperative day is crucial to prevent complications like deep vein thrombosis and aid in the recovery process. Elevating the legs while in bed can help with circulation but is not as effective in preventing complications related to immobility post-surgery. Repositioning every 2 hours is important for preventing pressure ulcers but does not directly address postoperative care. Maintaining bed rest for the first 24 hours postoperatively can increase the risk of complications associated with immobility, making early ambulation a more appropriate intervention.

5. Unlicensed assistive personnel (UAP) is assisting a client in traction. Which of these actions requires immediate intervention?

Correct answer: A

Rationale: The correct answer is A because traction weights should hang freely to maintain their effectiveness. Choice B is incorrect because providing pillows to cushion unaffected extremities is appropriate. Choice C is also incorrect as emptying the catheter bag is a routine nursing task. Choice D is incorrect as teaching the client to use the call light promotes client safety.
