When testing the patient's cranial nerves, the nurse should:
- A. Perform specific tests for each nerve, such as asking the patient to smile or follow an object with their eyes.
- B. Measure the patient's blood glucose levels.
- C. Inspect the patient's joints for swelling.
- D. Check the patient's peripheral pulses.
Correct Answer: A
Rationale: Testing cranial nerves involves specific assessments for each nerve, such as facial movements (cranial nerve VII) or eye movements (cranial nerves III, IV, and VI). Blood glucose levels, joint swelling, and peripheral pulses are unrelated to cranial nerve testing.

Any of the following cranial nerves has the parasympathetic nucleus EXCEPT:
- A. vagal
- B. oculomotor
- C. glossopharyngeal
- D. olfactory
Correct Answer: D
Rationale: Olfactory nerve is the correct answer because it is a sensory nerve responsible for the sense of smell and does not have a parasympathetic nucleus. In contrast, the vagus, oculomotor, and glossopharyngeal nerves all have parasympathetic components that regulate functions such as heart rate, pupil constriction, and salivation.
