A client with unstable angina is prescribed heparin therapy. The client asks the nurse about the purpose of this medication. How should the nurse respond?

"Heparin is used to dissolve blood clots in your coronary arteries and restore blood flow to your heart."

"It helps relax your blood vessels and improve blood flow to your heart muscle."

"Heparin is an anticoagulant that prevents further clot formation in your coronary arteries."

"It is a pain reliever used to reduce chest discomfort during episodes of angina."

Answer and Explanation

The Correct Answer is C

A) This choice is incorrect because heparin does not directly dissolve existing blood clots in coronary arteries. It is used to prevent further clot formation and growth.

B) This choice is incorrect because heparin's primary action is not to relax blood vessels. It is an anticoagulant that inhibits clot formation.

C) This choice is correct. Heparin is an anticoagulant medication used to prevent further clot formation in coronary arteries and reduce the risk of complications in clients with unstable angina.

D) This choice is incorrect because heparin is not a pain reliever. It does not directly address chest discomfort during angina episodes; its role is in preventing and managing thrombosis.

Correct Answer is C

Explanation

A) This choice is incorrect because sublingual nitroglycerin should not be swallowed with water. It is intended to dissolve under the tongue for rapid absorption into the bloodstream to provide quick relief from chest pain.

B) This choice is incorrect because the timing of nitroglycerin administration is not dependent on meals. Sublingual nitroglycerin should be taken as needed when chest pain occurs.

C) This choice is correct. Sublingual nitroglycerin is administered by placing the tablet under the tongue, where it dissolves and is absorbed directly into the bloodstream. This method allows for rapid onset of action and is used to relieve acute chest pain.

D) This choice is incorrect because sublingual nitroglycerin is not meant for daily or preventive use. It is specifically used to treat acute episodes of chest pain (angina) and should be taken only when needed. Clients with angina may be prescribed long-acting nitroglycerin preparations for prophylactic use, but sublingual nitroglycerin is intended for immediate relief of anginal symptoms.

Questions

A. "Oxygen reduces chest pain by dilating your coronary arteries." B. "Oxygen helps your heart pump blood more effectively." C. "Oxygen increases your oxygen levels and relieves shortness of breath." D. "Oxygen prevents further clot formation in your coronary arteries."

Correct Answer is C

Explanation

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.
