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.
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 A
Explanation
Choice A rationale
Stable angina typically occurs with exertion and goes away with rest. The symptoms described, including substernal pain, discomfort in the left shoulder and jaw, which subside with rest, are characteristic of stable angina.
Choice B rationale
Prinzmetal angina, also known as variant angina, is a type of angina (chest pain) caused by spasms in the coronary arteries. These spasms occur most often in coronary arteries that have not become hardened due to plaque buildup. However, they can also occur in hardened arteries. The symptoms can be similar to those of stable angina, but the typical triggers for the episodes are different.
Choice C rationale
A myocardial infarction (MI), or heart attack, occurs when one of the coronary arteries becomes blocked, often by a blood clot, causing part of the heart muscle to be damaged or die. The symptoms are usually more severe than what is described and do not typically subside with rest.
Choice D rationale
Unstable angina is a condition in which the angina symptoms become more severe, occur more frequently, or occur at rest. This is a medical emergency as it can often lead to a heart attack.
Correct Answer is D
Explanation
Choice A rationale
Elevating the leg above the level of the heart would not be beneficial in this case. This action would actually reduce blood flow to the leg, which is already compromised due to the arterial occlusion.
Choice B rationale
Exercising the leg would increase the oxygen demand of the tissues in the leg, which could exacerbate the problem. The tissues in the leg are already deprived of oxygen due to the arterial occlusion.
Choice C rationale
Applying a compression stocking to the leg would not be beneficial in this case. This action would further compromise blood flow to the leg, which is already reduced due to the arterial occlusion.
Choice D rationale
Keeping the patient in bed in the supine position is the correct action. This position will decrease the oxygen demand of the tissues in the leg and minimize ischemic damage until circulation can be restored.
