The nurse is providing care for a client admitted to the hospital after a motor vehicle accident. After being informed by family members that the patient is deaf and mute, which action should the nurse take?

Correct Answer: A

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

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.

Correct Answer: C

Rationale: The correct answer is C: muscarinic agonist. Atropine is an anticholinergic drug that blocks muscarinic receptors. Therefore, the antidote for atropine poisoning would be a muscarinic agonist, which competes with atropine for binding to muscarinic receptors and reverses its effects. Nicotinic agonist (A) would not be effective as atropine acts on muscarinic receptors, not nicotinic receptors. Anticholinergic (B) is the same class as atropine, so it would not counteract its effects. α-blocker (D) works on a different receptor system and would not be effective in treating atropine poisoning.

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.

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.
