A patient who has had 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?.

Cardiac-specific troponin.

Myoglobin.

Homocysteine.

C-reactive protein.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

Cardiac-specific troponin is a protein that is released into the bloodstream when there is damage to the heart muscle, such as during an acute myocardial infarction (AMI). It is considered the most specific marker for AMI because it is found only in heart muscle. The normal range for troponin I is between 0 and 0.04 ng/mL2.

Choice B rationale:

Myoglobin is a protein found in heart and skeletal muscles. While it can be elevated in AMI, it is not as specific as troponin because it is also found in skeletal muscles. The normal levels of myoglobin are 25 to 72 ng/mL4.

Choice C rationale:

Homocysteine is an amino acid in the blood, and high levels can increase the risk of heart disease. However, it is not specific for AMI5. The normal range of homocysteine levels are less than 15 micromoles per liter.

Choice D rationale:

C-reactive protein (CRP) is a marker of inflammation in the body and can be elevated in various conditions, including heart disease. However, it is not specific for AMI6. The normal CRP level is less than 0.9 milligrams per deciliter.

So, the correct answer is A, after analyzing all choices.

Correct Answer is ["B","C","D","F"]

Explanation

Choice A rationale:

The client’s temperature decreased from 37.6°C to 36.8°C1. This is within the normal body temperature range of 36.5°C to 37.2°C2, so it does not require further action.

Choice B rationale:

The client’s oxygen saturation decreased from 95% to 88%1. Normal pulse oximetry values are typically above 95%2. This decrease could indicate that the client is not getting enough oxygen, which requires further action.

Choice C rationale:

The client’s blood pressure increased from 108/50 mm Hg to 138/80 mm Hg. Normal blood pressure for adults is below 120/80 mm Hg. This increase could indicate worsening heart failure, which requires further action.

Choice D rationale:

The client’s weight increased from 80 kg to 82.1 kg. Rapid weight gain may be a sign of fluid retention, a common symptom of heart failure. This requires further action.

Choice E rationale:

The client’s urine output decreased from 480 mL/8 hr to 320 mL/8 hr.However it is still above 30ml/hr signifying normal renal function

Choice F rationale:

On Day 4, the client’s breath sounds were scattered, and crackles were heard bilaterally. This could indicate fluid accumulation in the lungs, a common symptom of heart failure. This requires further action.

So, the correct answer is Choices B, C, D, and F, after analyzing all choices.

A. "I can expect nausea as a side effect of nitroglycerin.”. B. "I will store the medication in a well-lit room.”. C. "I will call an ambulance if I have pain 5 minutes after taking nitroglycerin.”. D. "I should only take nitroglycerin when I have chest pain.”.

Correct Answer is C

Explanation

Choice A rationale:

Nitroglycerin can cause side effects such as headache and dizziness, but nausea is not a common side effect.

Choice B rationale:

Nitroglycerin should be stored in a dark, cool place, not in a well-lit room.

Choice C rationale:

This is the correct answer. If chest pain is not relieved 5 minutes after taking nitroglycerin, it is recommended to call an ambulance.

Choice D rationale:

While nitroglycerin is taken when chest pain occurs, it can also be taken prior to activities that might cause chest pain.

So, the correct answer is Choice C, after analyzing all choices.
