A nurse is providing education to a client with angina about stress management techniques. The client asks the nurse how stress affects the heart. How should the nurse respond?

"Stress causes the heart to pump faster, increasing blood flow to the body."

"It leads to vasodilation of the coronary arteries, improving blood flow to the heart."

"Stress triggers the release of adrenaline, which can constrict coronary arteries and increase heart rate."

"It suppresses the sympathetic nervous system, leading to decreased heart rate and blood pressure."

Answer and Explanation

The Correct Answer is C

A) This choice is incorrect because stress does not cause the heart to pump faster. While stress can activate the sympathetic nervous system and increase heart rate, the primary impact on the heart is related to hormonal responses.

B) This choice is incorrect because stress-induced vasodilation of coronary arteries is not a typical response. Instead, stress can lead to vasoconstriction, potentially reducing blood flow to the heart.

C) This choice is correct. During stress, the body releases adrenaline (epinephrine) and other stress hormones, which can lead to vasoconstriction of coronary arteries, reducing blood flow to the heart muscle. Additionally, the release of adrenaline can increase heart rate, resulting in increased myocardial oxygen demand.

D) This choice is incorrect because stress activates the sympathetic nervous system, leading to increased heart rate and blood pressure rather than suppressing these responses.

Correct Answer is D

Explanation

A) This choice is incorrect because inserting a stent is a part of percutaneous coronary intervention (PCI) and not coronary artery bypass grafting (CABG). CABG involves using blood vessels (grafts) to bypass blocked coronary arteries and restore blood flow to the heart.

B) This choice is incorrect because removing plaque from coronary arteries is not the primary purpose of CABG. CABG involves bypassing blocked arteries rather than removing the plaque.

C) This choice is incorrect because repairing damaged heart valves and improving cardiac function is a different surgical procedure, such as valve repair or replacement surgery. CABG does not address heart valve issues.

D) This choice is correct. Coronary artery bypass grafting (CABG) is a surgical procedure that involves taking a healthy blood vessel from another part of the body and grafting it to the blocked coronary artery. The graft bypasses the blockage, restoring blood flow to the heart and improving myocardial oxygen supply. CABG is used to treat significant coronary artery disease and improve cardiac function in clients with unstable angina or myocardial infarction.

A. "PCI is used to relieve chest pain and reduce inflammation in your heart muscle." B. "It involves the placement of a stent in your coronary artery to keep it open and improve blood flow to your heart." C. "PCI will help lower your blood pressure and improve your heart's pumping function." D. "It is a surgical procedure to bypass blocked coronary arteries and restore blood flow to your heart."

Correct Answer is B

Explanation

A) This choice is incorrect because while PCI can indirectly relieve chest pain by restoring blood flow to the heart, its primary purpose is not to reduce inflammation in the heart muscle.

B) This choice is correct. Percutaneous coronary intervention (PCI) involves the insertion of a catheter with a balloon at the tip into the blocked coronary artery. The balloon is inflated to compress the plaque and open the artery, and then a stent is placed to keep the artery open and improve blood flow to the heart.

C) This choice is incorrect because PCI's primary purpose is not to lower blood pressure but to restore blood flow to the heart by treating coronary artery blockages.

D) This choice is incorrect because the description provided is more characteristic of coronary artery bypass grafting (CABG) surgery, not PCI.
