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:

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.

A. A 65-year-old patient who had a myocardial infarction (MI) 4 days ago and is anxious about today's planned discharge. B. A 59-year-old patient with unstable angina who has just returned after a percutaneous coronary intervention (PCI). C. A 56-year-old patient with variant angina who is scheduled to receive nifedipine (Procardia). D. A 39-year-old patient with pericarditis who is complaining of sharp, stabbing chest pain.

Correct Answer is B

Explanation

Choice A rationale:

A patient who had a myocardial infarction (MI) 4 days ago and is anxious about today’s planned discharge would need reassurance and education, but it’s not an immediate concern.

Choice B rationale:

A patient with unstable angina who has just returned after a percutaneous coronary intervention (PCI) is at risk for hemorrhage from the arterial access site. Immediate assessment of blood pressure, pulses, and the access site is required.

Choice C rationale:

A patient with variant angina who is scheduled to receive nifedipine (Procardia) would need monitoring, but it’s not the most urgent.

Choice D rationale:

A patient with pericarditis complaining of sharp, stabbing chest pain would need evaluation, but the risk of complications is less immediate than for Choice B1.

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