Which of the following medications are going to dilate the coronary arteries and redirect blood flow so that ischemic tissue is oxygenated?

Salmeterol

Aspirin

Digoxin

Nitroglycerin

Answer and Explanation

The Correct Answer is D

Choice A reason: Salmeterol, a long-acting bronchodilator, opens airways in asthma or COPD but doesn’t dilate coronary arteries or improve cardiac ischemia, targeting lungs instead.

Choice B reason: Aspirin prevents clotting by inhibiting platelet aggregation, reducing ischemia risk, but it doesn’t directly dilate coronary arteries or acutely redirect blood flow.

Choice C reason: Digoxin increases cardiac contractility in heart failure, improving output, but it doesn’t dilate coronary vessels or specifically oxygenate ischemic myocardium.

Choice D reason: Nitroglycerin, a vasodilator, relaxes coronary arteries, increasing blood flow to ischemic areas, relieving angina by enhancing oxygen delivery to the heart muscle.

Correct Answer is B

Explanation

Choice A reason: Dressing involves both sides but can be adapted with the left hand; right-sided CVA impairs left-side function, less affecting dominant right-hand tasks.

Choice B reason: Writing, a fine motor skill, relies on the dominant right hand, controlled by the left brain; right-sided CVA disrupts this, making it most difficult.

Choice C reason: Combing hair uses gross motor skills, manageable with the left hand despite right-sided CVA’s left-sided weakness, less challenging than writing.

Choice D reason: Eating uses the right hand but can be adjusted with utensils or left-hand assistance; it’s less precise than writing, so less impacted.

A. She has stopped speaking to all of us B. She has difficulty using her toothbrush and comb C. She seems forgetful and takes longer to do daily tasks D. She has lost control of her bladder and bowel

Correct Answer is C

Explanation

Choice A reason: Stopping speech entirely suggests advanced Alzheimer’s or aphasia, not mild, where memory and task performance decline first, not communication fully.

Choice B reason: Difficulty with toothbrush and comb indicates moderate Alzheimer’s, where motor apraxia emerges, beyond mild stage’s primary memory issues.

Choice C reason: Forgetfulness and slower task completion reflect mild Alzheimer’s early memory loss and executive dysfunction, impairing planning, consistent with initial stages.

Choice D reason: Bladder and bowel incontinence occur in late Alzheimer’s from severe brain damage, not mild, where cognitive, not physical, decline predominates.
