KL is a 34-year-old male admitted to the hospital (large trauma center) after suffering a traumatic brain injury (TBI) secondary to a serious motor vehicle accident. He was in excellent health prior to the accident. HT: 6'2" WT: 190 pounds (86 kg) What is the best means of determining KL's caloric needs while in the hospital?

Correct Answer: D

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: A

Rationale: Peripheral nerves are the correct answer because a glove-and-stocking pattern of sensory loss is characteristic of peripheral neuropathy. This pattern occurs due to the length-dependent nature of peripheral nerve damage, where the longest nerves (those supplying the hands and feet) are affected first, leading to distal sensory deficits.

Correct Answer: B

Rationale: Carry out an imagined act is the correct answer because apraxia is a motor disorder characterized by the inability to perform purposeful movements, despite having the physical ability and desire to do so. This condition results from damage to the parietal lobe or other areas involved in motor planning.

Correct Answer: D

Rationale: Cerebral cortex is the correct answer because the autonomic nervous system (ANS) primarily consists of the hypothalamus, brainstem, and peripheral nerves, which regulate involuntary bodily functions. The cerebral cortex, however, is involved in higher cognitive functions and voluntary motor control, and is not part of the ANS.

Correct Answer: B

Rationale: The conduction velocity is calculated as the distance traveled divided by the time taken. Here, the distance between the anode and cathode is 6 cm + 4.5 cm = 10.5 cm (0.105 m). The time taken is the latent period of 1.5 ms (0.0015 s). Thus, conduction velocity = 0.105 m / 0.0015 s = 70 m/s. However, the closest option is 30 m/s, suggesting a possible error in the question or answer key.
