A patient who has been experiencing chest pain for several hours is admitted with a diagnosis of rule out acute myocardial infarction (AMI). Which laboratory test is most specific for the nurse to monitor in determining whether the patient has had an AMI?

Homocysteine.

C-reactive protein.

Myoglobin.

Cardiac-specific troponin.

Answer and Explanation

The Correct Answer is D

Choice A rationale
Homocysteine is an amino acid that your body uses to make protein and to build and maintain tissue. But too much homocysteine in your blood might increase your risk of heart disease.
However, it is not the most specific marker for AMI.
Choice B rationale
C-reactive protein (CRP) is produced by the liver and its level rises when there is inflammation in your body. While its level can increase in those with a heart attack, it is not the most specific marker for AMI6.
Choice C rationale
Myoglobin is a small protein that stores oxygen. It is measured occasionally. Myoglobin is sometimes measured in addition to troponin to help diagnose a heart attack. However, it is not as specific as cardiac-specific troponin.
Choice D rationale
Cardiac-specific troponin is a cardio-specific, highly sensitive marker for myocardial damage. The absolute cardiospecificity of cTnI allows the diagnosis of myocardial infarction distinct from muscle lesions and non-cardiac surgery.

Correct Answer is C

Explanation

Choice A rationale
While assessing the gag reflex is important in certain situations, such as after surgery involving anesthesia, it is not typically a crucial assessment following Percutaneous Transluminal Angioplasty (PTA) of the lower extremity.
Choice B rationale
Checking for dye allergies is important before a procedure that uses contrast dye. However, it is not a crucial post-procedure assessment.
Choice C rationale
Monitoring of pedal pulses is crucial following PTA of the lower extremity. This is because the procedure involves the arteries in the legs, and monitoring pedal pulses can help assess blood flow to the area and detect potential complications such as occlusion or clot formation.
Choice D rationale
While the Ankle-Brachial Index can be used to diagnose Peripheral Arterial Disease (PAD), it is not typically a crucial assessment immediately following PTA3.

A. Implementing a smoking cessation program. B. Treating the specific etiological disease. C. Initiating a rapid weight-loss program. D. Starting a rigorous exercise regimen.

Correct Answer is B

Explanation

Choice A rationale
Implementing a smoking cessation program, while beneficial for overall health and cardiovascular risk reduction, is not the primary therapeutic goal for secondary hypertension. Secondary hypertension is high blood pressure caused by an underlying condition. Therefore, the primary goal is to treat the underlying condition.
Choice B rationale
Treating the specific etiological disease is the primary therapeutic goal for secondary hypertension. By treating the underlying cause, blood pressure can often be lowered or returned to normal.
Choice C rationale
Initiating a rapid weight-loss program is not the primary therapeutic goal for secondary hypertension. While weight loss can help lower blood pressure in general, the primary goal in secondary hypertension is to treat the underlying cause.
Choice D rationale
Starting a rigorous exercise regimen, while beneficial for overall health and cardiovascular risk reduction, is not the primary therapeutic goal for secondary hypertension. The primary goal is to treat the underlying condition causing the high blood pressure.
