A patient is admitted to the emergency department and diagnosed as having an ST-segment-elevation myocardial infarction (STEMI). Which question would the nurse ask to determine whether the patient is a candidate for thrombolytic therapy?.

"Did you take aspirin today?".

"Do you have any allergies?".

"Can you rate the pain on a 0 to 10 scale?".

"What time did your pain begin?". .

Answer and Explanation

The Correct Answer is D

Choice A rationale:

While aspirin is often given to patients with suspected myocardial infarction, asking if the patient took aspirin does not help determine the timing of the onset of symptoms.

Choice B rationale:

Knowing the patient’s allergies is important for medication safety, but it does not help determine eligibility for thrombolytic therapy.

Choice C rationale:

Rating the pain on a scale helps assess the severity of the pain, but it does not provide information about the timing of the onset of symptoms.

Choice D rationale:

The time of pain onset is crucial in determining eligibility for thrombolytic therapy. Thrombolytic therapy is most effective when given within a certain time frame from the onset of symptoms.

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

Correct Answer is A

Explanation

Choice A rationale:

Chest pain that lasts for 20 minutes or more is characteristic of an acute myocardial infarction (AMI)123.

Choice B rationale:

Changes in pain that occur with deep breathing are more typical of musculoskeletal pain or pericarditis.

Choice C rationale:

Stable angina is usually relieved when the patient takes nitroglycerin.

Choice D rationale:

Pain that is reproducible when the patient raises the arms is more typical of musculoskeletal pain.

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

A. Cardiac-specific troponin. B. Myoglobin. C. Homocysteine. D. C-reactive protein.

Correct Answer is A

Explanation

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.
