What is the primary therapeutic goal for secondary hypertension?

Choice A rationale
Increasing glomerular filtration would result in increased urine output, not decreased venous return. This action is not directly related to the therapeutic action of nitroglycerin.
Choice B rationale
While enhancing the contractility of the myocardium would increase oxygen delivery, this is not the primary action of nitroglycerin. Nitroglycerin primarily works by dilating the blood vessels, which reduces the amount of work the heart has to do and increases the blood supply to the heart muscle.
Choice C rationale
Nitroglycerin does not produce an immediate analgesic effect. While it can relieve chest pain, it does so by increasing blood flow to the heart, not by acting as an analgesic.
Choice D rationale
Nitroglycerin increases the coronary blood supply and decreases the afterload314. By dilating the blood vessels, nitroglycerin reduces the amount of work the heart has to do and increases the blood supply to the heart muscle. This is the primary therapeutic action of nitroglycerin in alleviating chest pain.

Choice A rationale
Ulceration on the medial surface of the lower legs is not the best description of stasis dermatitis in a patient with peripheral vascular disease (PVD). While ulcers can occur in severe cases, they are not the primary characteristic of stasis dermatitis.
Choice B rationale
Stasis dermatitis, also known as venous stasis dermatitis, is a skin inflammation that occurs in people with poor circulation. It most often happens in the lower legs because that’s where blood typically collects. When blood pools in the veins of the lower leg, it can cause a variety of symptoms, including a brownish skin discoloration on the lower legs. This discoloration is caused by the leakage of red blood cells into the skin due to increased pressure in the veins.
Choice C rationale
While edema in the lower legs can be a symptom of PVD and may accompany stasis dermatitis, it is not the best description of the condition. Edema is a general symptom that can occur in many conditions and is not specific to stasis dermatitis.
Choice D rationale
A purple rash on the medial surface of the lower legs is not a typical symptom of stasis dermatitis. While the skin may become discolored, it is usually a brownish color rather than purple.
