A patient presents to the ER with numbness in the left arm, a severe headache, and trouble speaking. Which of the following diagnostic tests do you anticipate the healthcare provider to order?
CT scan
Hemoglobin and hematocrit
MRI
Pulmonary angiography
The Correct Answer is A
Choice A reason: CT scan rapidly detects ischemic stroke or hemorrhage in the brain, critical for numbness, headache, and speech issues, guiding urgent treatment decisions.
Choice B reason: Hemoglobin and hematocrit assess blood count, not brain pathology like stroke, which requires imaging to identify infarction or bleeding, not anemia.
Choice C reason: MRI offers detailed stroke imaging but is slower than CT, less ideal for acute ER settings needing immediate diagnosis of neurological symptoms.
Choice D reason: Pulmonary angiography evaluates lung vessels for embolism, irrelevant to stroke symptoms (numbness, headache, speech difficulty), which localize to brain issues.

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: Emphysema destroys alveoli, causing air trapping and dyspnea, but doesn’t involve excessive mucus production, focusing on structural loss, not glandular activity.
Choice B reason: Peripheral vascular disease impairs arterial flow, causing ischemia and pain, not affecting airways or mucus glands, unrelated to respiratory secretions.
Choice C reason: Heart failure leads to fluid in alveoli (edema), causing crackles, but not excessive mucus, as it’s a circulatory, not inflammatory airway issue.
Choice D reason: Bronchitis inflames bronchial tubes, overactivating goblet cells to produce excess mucus, leading to productive cough, a hallmark of this condition.
