What nursing assessment finding would suggest inadequate renal perfusion in a patient being stabilized after an acute coronary syndrome (myocardial infarction)?

Low urine osmolarity and creatinine clearance.

Decreasing serum blood urea nitrogen (BUN) level.

Urine output of less than 30 mL/hr.

Urine specific gravity of less than 1.010.

Answer and Explanation

The Correct Answer is C

Choice A rationale
Low urine osmolarity and creatinine clearance are not the primary indicators of inadequate renal perfusion in a patient being stabilized after an acute coronary syndrome. These measures reflect the concentration of the urine and the kidney’s ability to filter waste from the blood, respectively. While they can be affected by renal perfusion, they are not the most direct or reliable indicators.
Choice B rationale
A decreasing serum blood urea nitrogen (BUN) level is not typically associated with inadequate renal perfusion. In fact, a high BUN level may indicate that the kidneys aren’t working properly. However, BUN levels can be influenced by many factors, including protein intake and liver function, so they are not the most reliable indicator of renal perfusion.
Choice C rationale
A urine output of less than 30 mL/hr is a common sign of inadequate renal perfusion. The kidneys need adequate blood flow to filter waste products from the blood and produce urine. If renal perfusion is inadequate, urine output can decrease.
Choice D rationale
A urine-specific gravity of less than 1.010 is not typically associated with inadequate renal perfusion. Specific gravity is a measure of the concentration of solutes in the urine. It can be influenced by hydration status and certain kidney disorders, but it is not a direct measure of renal perfusion.

Correct Answer is B

Explanation

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.

A. Daily alcohol use. B. Myocardial infarction (MI). C. Asthma. D. Peptic ulcer disease.

Correct Answer is C

Explanation

Choice A rationale
Daily alcohol use is not a direct contraindication for Propranolol (Inderal), but it’s important to note that alcohol can increase the blood pressure-lowering effect of propranolol, which can make you feel dizzy or lightheaded.
Choice B rationale
Propranolol is often used in the treatment of conditions related to heart disease, such as hypertension and angina, and it can also be used in the secondary prevention of myocardial infarction.
Choice C rationale
Asthma is a contraindication for the use of Propranolol (Inderal). Propranolol can cause bronchial constriction by blocking beta-adrenergic receptors in the lungs, which can exacerbate asthma symptoms.
Choice D rationale
Peptic ulcer disease is not a direct contraindication for Propranolol (Inderal). However, like any medication, Propranolol should be used with caution in patients with a history of peptic ulcer disease.
