Which of these cranial nerves contains preganglionic parasympathetic fibers?
- A. optic, CN II
- B. facial, CN VII
- C. trigeminal, CN V
- D. hypoglossal, CN XII
Correct Answer: B
Rationale: The correct answer is B: facial nerve, CN VII. The facial nerve contains preganglionic parasympathetic fibers that innervate the lacrimal, submandibular, and sublingual glands. These fibers originate from the superior salivatory nucleus in the pons. Option A (optic nerve) is involved in vision and not related to parasympathetic function. Option C (trigeminal nerve) is primarily involved in sensory innervation of the face and motor function of the muscles of mastication. Option D (hypoglossal nerve) is responsible for motor control of the tongue and is not associated with parasympathetic fibers.

What is a normal finding when assessing a patient's deep tendon reflexes?
- A. An involuntary contraction of the muscle being tested.
- B. Absence of any reflexive response.
- C. Decreased or diminished reflexes.
- D. Hyperactive reflexes with clonus.
Correct Answer: A

The nurse practitioner is reviewing the chart of a patient who is scheduled to receive their first dose of sumatriptan (Imitrex) in the clinic today. Past medical history is positive for only migraines. Which of the following requires further evaluation before the medication is administered?
- A. Recent naproxen (Naprosyn) use
- B. Current blood pressure 142/90 mmHg
- C. Resting pulse rate of 61 bpm
- D. Adverse reaction to ubrogepant (Ubrelvy)
Correct Answer: B
Rationale: The correct answer is B: Current blood pressure 142/90 mmHg. Before administering sumatriptan, the nurse practitioner should further evaluate the patient's elevated blood pressure to ensure it is not contraindicated for the medication. Sumatriptan can potentially increase blood pressure, so it is crucial to monitor and address any hypertension before giving the medication.
Choice A: Recent naproxen use is not a direct contraindication for sumatriptan. Both medications are commonly used together for migraine treatment.
Choice C: A resting pulse rate of 61 bpm is within the normal range and does not require further evaluation before administering sumatriptan.
Choice D: Adverse reaction to ubrogepant is not relevant for evaluating the safety of sumatriptan. Each medication has its own set of potential side effects and interactions.
