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. Engaging in regular physical activity and maintaining a healthy weight are effective strategies for reducing the risk of MI. Physical activity helps improve cardiovascular health, manage weight, and reduce other risk factors like hypertension and diabetes.

B) This choice is incorrect because while limiting saturated fat intake is important for heart health, it is not the most effective approach to lower the risk of MI when compared to engaging in physical activity and maintaining a healthy weight.

C) This choice is incorrect because quitting smoking and reducing alcohol consumption are essential for reducing the risk of MI, but they may not be as effective as regular physical activity and weight management.

D) This choice is incorrect because controlling stress through relaxation techniques and counseling is beneficial for overall well-being, but it may not be the most effective approach to reduce the risk of MI when compared to regular physical activity and weight management. Stress management is still an important aspect of cardiovascular health, but it should be combined with other lifestyle changes for optimal risk reduction.

Questions

A. "Aspirin helps dilate your coronary arteries and increase blood flow to your heart." B. "It prevents blood clot formation and reduces the risk of further blockages in your coronary arteries." C. "Aspirin lowers your blood pressure and helps your heart pump more efficiently." D. "It is used to relieve chest pain and reduce inflammation in your heart muscle."

Correct Answer is B

Explanation

A) This choice is incorrect because aspirin does not directly dilate coronary arteries. Aspirin's primary action in MI management is its antiplatelet effect, which prevents platelets from clumping together and forming blood clots in coronary arteries, reducing the risk of further blockages.

B) This choice is correct. Aspirin is commonly prescribed during an acute MI to prevent blood clot formation and reduce the risk of further blockages in the coronary arteries. It is a crucial medication in the management of acute coronary syndrome.

C) This choice is incorrect because aspirin's primary action is not to lower blood pressure or improve cardiac pumping efficiency. These actions are typically achieved through other medications, such as beta-blockers or ACE inhibitors, in the management of MI.

D) This choice is incorrect because while aspirin is used to relieve pain and reduce inflammation, its primary role in MI management is its antiplatelet effect, as mentioned earlier.
