Correct Answer: A

Rationale: The correct answer is A: Creatinine. Creatinine is a waste product produced by muscles and excreted by the kidneys. An elevated creatinine level indicates impaired kidney function, making it a key indicator for early detection of renal failure. Blood urea nitrogen (BUN) can also be elevated in renal failure, but creatinine is a more specific and sensitive marker. Sodium and potassium levels are not directly related to renal failure detection.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Total parenteral nutrition (TPN) can cause adrenal insufficiency. 2. Corticosteroids help prevent adrenal insufficiency in TPN patients. 3. Monitoring corticosteroid administration ensures adrenal function. 4. Monitoring blood glucose or serum glucose levels is important but not specific to TPN. 5. Dehydration can be monitored but is not directly related to TPN.

Correct Answer: B

Rationale: The correct hand position for performing chest vibration is to spread the fingers. This allows for a larger surface area of contact with the chest, promoting effective transmission of vibrations to loosen chest secretions. Flattening the hands would reduce the effectiveness of the vibrations by limiting contact area. Cupping the hands creates a smaller contact area and may concentrate the pressure too much in one spot, potentially causing discomfort or injury. Therefore, spreading the fingers is the optimal hand position for chest vibration technique.
