A client is admitted to the emergency room with chest pain and a suspected diagnosis of acute myocardial infarction (MI). Which test would the nurse expect the physician to order to make a definitive diagnosis of MI?
Complete blood count (CBC).
Lipid profile.
Electrocardiogram (ECG).
Troponin levels.
The Correct Answer is D
Choice A rationale
A complete blood count (CBC) can provide general information about the body's response to an MI, such as white blood cell count, but it is not definitive for diagnosing an MI.
Choice B rationale
A lipid profile measures cholesterol levels and helps assess cardiovascular risk, but it is not useful for diagnosing an acute MI.
Choice C rationale
An electrocardiogram (ECG) is essential for diagnosing an MI as it shows the heart's electrical activity and can indicate ischemia or infarction.
Choice D rationale
Troponin levels are the most specific and sensitive markers for myocardial infarction. Elevated troponin levels confirm heart muscle damage due to an MI, making it the definitive test.

Correct Answer is A
Explanation
Choice A rationale
A terminal ileostomy involves creating an opening in the right lower quadrant of the abdomen where the ileum is brought to the surface to form a stoma for waste elimination.
Choice B rationale
The left lower quadrant is not used for a terminal ileostomy, as it is not anatomically appropriate for the ileum.
Choice C rationale
The right upper quadrant is not relevant to a terminal ileostomy because the ileum is located in the lower part of the abdomen.
Choice D rationale
The left upper quadrant is also inappropriate for a terminal ileostomy due to the anatomical position of the ileum.
Correct Answer is A
Explanation
Choice A rationale
Administering a prescribed bronchodilator medication is the priority action for a patient experiencing an acute asthma attack. This helps to open the airways and improve breathing.
Choice B rationale
While checking the patient's vital signs is important, it is not the first action in the acute management of an asthma attack. The immediate priority is to relieve bronchospasm.
Choice C rationale
Collecting a sputum sample for analysis is not the first priority in an acute asthma attack. Stabilizing the patient's breathing is more urgent.
Choice D rationale
Obtaining a detailed health history is essential for comprehensive care but is not the first action during an acute asthma attack. Rapid intervention to improve breathing is the priority.
