A client with angina pectoris reports chest pain and is receiving oxygen therapy. The client asks the nurse about the purpose of oxygen administration. How should the nurse respond?

"Oxygen reduces chest pain by dilating your coronary arteries."

"Oxygen helps your heart pump blood more effectively."

"Oxygen increases your oxygen levels and relieves shortness of breath."

"Oxygen prevents further clot formation in your coronary arteries."

Answer and Explanation

The Correct Answer is C

A: Oxygen does not directly dilate coronary arteries; medications such as nitrates are responsible for this effect.
B: While oxygen aids in metabolic processes, it does not directly affect the heart's pumping efficiency in the context of angina pectoris.
C: Oxygen therapy increases the oxygen saturation of the blood, which can help alleviate symptoms like shortness of breath and chest pain associated with angina by ensuring that the heart muscle receives sufficient oxygen to function properly.
D: Oxygen therapy is not a treatment for preventing clot formation; this is typically managed with anticoagulant medications.

Correct Answer is A

Explanation

A) This choice is correct. An electrocardiogram (ECG) is one of the primary diagnostic tests used to confirm the diagnosis of a myocardial infarction (MI). An ECG can show characteristic changes, such as ST-segment elevation or Q waves, indicative of myocardial ischemia and injury.

B) This choice is incorrect because an echocardiogram is a useful imaging test to assess the heart's structure and function, but it is not the primary diagnostic test for confirming an MI.

C) This choice is incorrect because a magnetic resonance imaging (MRI) is a valuable tool for assessing heart function and detecting certain cardiac abnormalities, but it is not typically the initial diagnostic test for MI.

D) This choice is incorrect because a chest X-ray can help identify other conditions like pulmonary edema or lung disorders, but it is not the primary diagnostic test for MI.

A. "Coronary angiography will measure the levels of cardiac biomarkers in your blood." B. "It is a stress test that evaluates your heart's response to increased demand." C. "The test involves injecting dye into your coronary arteries to visualize any blockages." D. "Coronary angiography will assess your heart's function using sound waves."

Correct Answer is C

Explanation

A) This choice is incorrect because measuring the levels of cardiac biomarkers in the blood is not the purpose of coronary angiography. Cardiac biomarkers are measured through blood tests to diagnose conditions like myocardial infarction (MI).

B) This choice is incorrect because a stress test evaluates the heart's response to increased demand and is different from coronary angiography.

C) This choice is correct. Coronary angiography is an invasive procedure that involves injecting a contrast dye into the coronary arteries. The dye allows visualization of the coronary arteries and identifies any blockages or narrowing that may be causing angina or other cardiac symptoms.

D) This choice is incorrect because assessing the heart's function using sound waves is characteristic of an echocardiogram, not coronary angiography.
