Correct Answer: C

Rationale: Taking levothyroxine in the morning on an empty stomach (30-60 minutes before food or other medications) ensures optimal absorption and efficacy for treating hypothyroidism.
Choice A is wrong because taking levothyroxine with a meal can reduce absorption, decreasing its effectiveness; it should be taken on an empty stomach.
Choice B is wrong because it typically takes 4-6 weeks for levothyroxine to stabilize thyroid hormone levels and for symptoms to improve, not 1 week.
Choice D is wrong because thyroid function tests are typically checked every 6-8 weeks initially to adjust the dose, then every 6-12 months once stable, not automatically every 12 months.

Correct Answer: A

Rationale: Encouraging the client to log-roll when turning prevents twisting of the spine, maintaining alignment and reducing strain on the surgical site after a lumbar laminectomy.
Choice B is incorrect because a prone position is uncomfortable and not recommended post-laminectomy; a side-lying or semi-Fowler's position is preferred.
Choice C is incorrect because a heating pad is not typically used, as it may increase swelling; cold packs are often applied initially.
Choice D is incorrect because ambulation is usually encouraged on the first postoperative day, not delayed to the second, unless contraindicated.

Correct Answer: B

Rationale: Completing the full course of amoxicillin ensures eradication of the bacterial infection causing otitis media, preventing recurrence or antibiotic resistance.
Choice A is incorrect because amoxicillin should not be taken with an antacid, as it does not significantly reduce stomach upset and may affect absorption.
Choice C is incorrect because diarrhea, if it occurs, is typically a side effect during treatment and should resolve after completion; persistent diarrhea requires evaluation.
Choice D is incorrect because amoxicillin suspension should be refrigerated, not stored at room temperature, to maintain stability.

Correct Answer: A

Rationale: Nystagmus (involuntary eye movements) is a common manifestation of multiple sclerosis due to demyelination affecting the optic nerve or cerebellar pathways, impacting vision and coordination.
Choice B is incorrect because multiple sclerosis typically causes hyperactive deep tendon reflexes due to upper motor neuron involvement, not hypoactive reflexes.
Choice C is incorrect because persistent nausea is not a hallmark symptom of multiple sclerosis; it may occur secondary to medications or other conditions.
Choice D is incorrect because fever is not typical unless the client has an infection or is experiencing a pseudoexacerbation triggered by heat.

Correct Answer: C

Rationale: The nurse should not assume that the client's hallucinations are related to medication noncompliance, as this can be perceived as accusatory and judgmental. The nurse should not focus on the duration of the hallucinations, as this is not the priority at this time. The nurse should ask the client what the voices are telling them, because this can help assess the client's risk for harm to self or others, and also show empathy and respect for the client's experience. The nurse should not invalidate the client's reality by stating that they do not hear anything, as this can cause mistrust and alienation.
