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

Choice A rationale
Orthostatic hypotension, a form of low blood pressure that happens when you stand up from sitting or lying down, would not typically cause severe chest pain or result in elevated levels of cardiac troponins I and T6.
Choice B rationale
Raynaud’s disease, a condition that causes some areas of your body — such as your fingers and toes — to feel numb and cold in response to cold temperatures or stress, would not typically cause severe chest pain or result in elevated levels of cardiac troponins I and T6.
Choice C rationale
Angina, a type of chest pain caused by reduced blood flow to the heart, could cause severe chest pain, but it would not typically result in elevated levels of cardiac troponins I and T6. Elevated troponin levels are more indicative of damage to the heart muscle, which is not characteristic of angina.
Choice D rationale
A myocardial infarction (MI), also known as a heart attack, could cause severe chest pain and would typically result in elevated levels of cardiac troponins I and T7. Troponins are proteins found in the heart muscle, and levels can rise in the blood when there is damage to the heart, such as during an MI.

Choice A rationale
Education on the necessity of continuous antibiotic prophylaxis is crucial for patients who have just recovered from rheumatic fever. Rheumatic fever is an inflammatory disease that can develop as a complication of untreated or inadequately treated strep throat or scarlet fever.
Patients who have had rheumatic fever are at risk of getting it again if they have another strep infection. Continuous antibiotic prophylaxis can prevent recurrent infections and the development of rheumatic heart disease.
Choice B rationale
While anticoagulation therapy may be necessary for some patients with heart conditions, it is not typically the most important nursing action for a patient who has just recovered from rheumatic fever. Rheumatic fever can cause inflammation and damage to the heart valves, but it does not typically cause blood clots, which are the primary reason for anticoagulation therapy.
Choice C rationale
Adherence to standard infection control procedures is important for all patients, but it is not the most important nursing action for a patient who has just recovered from rheumatic fever. The primary concern for these patients is preventing recurrent strep infections, which can be achieved through continuous antibiotic prophylaxis.
Choice D rationale
While physical activity management may be part of the overall care plan for a patient who has just recovered from rheumatic fever, it is not typically the most important nursing action. The primary concern for these patients is preventing recurrent strep infections, which can be achieved through continuous antibiotic prophylaxis.
