A patient with dilated cardiomyopathy has recently developed atrial fibrillation that has been unresponsive to drug therapy for several days.

What topic should the nurse plan to include in patient teaching?

Choice A rationale
Administering Lasix (a diuretic) would not be the most immediate intervention for a patient experiencing increased chest pain after taking sublingual nitroglycerin. Lasix is used to treat fluid retention (edema) and swelling caused by congestive heart failure, liver disease, kidney disease, and other medical conditions. It works by causing the kidneys to get rid of unneeded water and salt from the body into the urine.
Choice B rationale
The most important nursing intervention for a patient experiencing increased chest pain after taking sublingual nitroglycerin would be to increase myocardial oxygenation. This can be achieved by administering supplemental oxygen and ensuring the patient is in a position that maximizes respiratory efficiency (such as semi-Fowler’s position). This intervention addresses the immediate life-threatening situation of myocardial ischemia.
Choice C rationale
Obtaining one hour of echocardiogram readings would not be the most immediate intervention for a patient experiencing increased chest pain after taking sublingual nitroglycerin. While an echocardiogram can provide valuable information about the structure and function of the heart, it is not the first step in managing acute chest pain.
Choice D rationale
Decreasing the patient’s anxiety is an important aspect of care, but it is not the most immediate intervention for a patient experiencing increased chest pain after taking sublingual nitroglycerin. The priority is to address the physical cause of the 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.
