Neurological Review of Systems Questions Questions
Question 1 of 5
Which of these cranial nerves contains preganglionic parasympathetic fibers?
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.
Question 2 of 5
Which of these diseases does NOT require the introduction of foreign nucleic acid?
Correct Answer: A
Rationale: The correct answer is A (kuru) because kuru is a prion disease caused by misfolded proteins, not foreign nucleic acid. Polio, rabies, and St. Louis encephalitis are caused by viruses, which contain foreign nucleic acid. Prions do not contain nucleic acid and replicate by inducing misfolding of normal cellular proteins. Therefore, kuru does not require the introduction of foreign nucleic acid for its transmission and development.
Question 3 of 5
While gathering equipment after an injection, a nurse accidentally received a prick from an improperly capped needle. To interpret this sensation, which of these areas must be intact?
Correct Answer: C
Rationale: The correct answer is C: Lateral spinothalamic tract, thalamus, and sensory cortex. The lateral spinothalamic tract carries pain and temperature sensations to the thalamus, which then relays it to the sensory cortex for interpretation. In this scenario, the nurse's sensation of being pricked by the needle is a pain sensation, so the intactness of the lateral spinothalamic tract, thalamus, and sensory cortex is crucial for interpreting this sensation. Choices A, B, and D are incorrect because they do not involve the specific pathways responsible for transmitting pain sensations. The corticospinal tract (choice A) is involved in motor function, the pyramidal tract (choice B) is involved in voluntary movement, and the anterior spinothalamic tract (choice D) is not associated with pain and temperature sensations. Therefore, the correct answer is C as it directly relates to the interpretation of the pain sensation experienced by the nurse.
Question 4 of 5
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?
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.
Question 5 of 5
A nurse assesses a patient diagnosed with functional neurological (conversion) disorder. Which comment is most likely from this patient?
Correct Answer: A
Rationale: Step-by-step rationale: 1. The correct answer is A because the patient's symptoms (shortness of breath and left arm pains) do not have a clear medical explanation, indicating a functional neurological disorder. 2. The patient attributing symptoms to indigestion suggests a psychological rather than physical origin. 3. Choices B, C, and D describe physical symptoms with potential organic causes, not typically associated with conversion disorder. 4. B is more indicative of gastrointestinal issues, C of sexual dysfunction, and D of possible esophageal pathology, making them less likely in a conversion disorder context.
