The nurse is caring for a 32-year-old woman who has an enlarged thyroid, bulging eyes, and elevated T3 and T4 levels and states she has not had a menstrual cycle in 6 months. She also states she has tremors and keeps losing weight without trying. Which of the following medications would the nurse anticipate being ordered?
Hydroxychloroquine
Levothyroxine
Potassium iodide
Methotrexate
The Correct Answer is C
Choice A reason: Hydroxychloroquine treats autoimmune diseases like lupus by modulating immunity, not hyperthyroidism’s excess thyroid hormone production, irrelevant here.
Choice B reason: Levothyroxine supplements thyroid hormone in hypothyroidism, worsening this patient’s hyperthyroidism (high T3/T4), contraindicated for her symptoms.
Choice C reason: Potassium iodide inhibits thyroid hormone release, reducing T3 and T4 in hyperthyroidism (e.g., Graves’), addressing her goiter, exophthalmos, and weight loss effectively.
Choice D reason: Methotrexate suppresses immunity in cancer or autoimmunity, not targeting thyroid overactivity or hormone levels, unsuitable for hyperthyroidism management.

Correct Answer is D
Explanation
Choice A reason: Soft foods like applesauce aid swallowing in Parkinson’s dysphagia, reducing aspiration risk from rigidity, a correct self-management strategy.
Choice B reason: Prune juice relieves constipation, common in Parkinson’s from slowed gut motility due to dopamine loss, so this is an accurate statement.
Choice C reason: Carbidopa-levodopa boosts dopamine, easing Parkinson’s motor symptoms (tremors, rigidity), a standard treatment, making this statement correct.
Choice D reason: Parkinson’s stems from dopamine deficiency, not acetylcholine; excess acetylcholine worsens symptoms, so this is incorrect and needs teaching.
Correct Answer is D
Explanation
Choice A reason: Maintaining oxygen saturation helps symptoms but doesn’t diagnose the cause (e.g., MI), delaying critical evaluation of atypical pain and dyspnea.
Choice B reason: Ibuprofen relieves pain but risks bleeding in potential MI, not addressing cardiac etiology of jaw, back pain, and shortness of breath urgently.
Choice C reason: Acetaminophen eases pain but doesn’t assess or treat potential cardiac ischemia, missing the diagnostic priority for these MI-like symptoms.
Choice D reason: An EKG identifies cardiac ischemia (e.g., MI) in atypical pain (jaw, back), dyspnea, and nausea, guiding urgent treatment, the priority action here.
