• GERD

A patient with unstable angina asks how it differs from stable angina. The nurse responds:

• It is predictable and occurs with exertion

• It is relieved by rest

• It is sudden, occurs even at rest, and may not be relieved by nitroglycerin

• It is not related to heart perfusion

Which cardiac marker is typically not elevated in unstable angina?

• Troponin I

• CK-MB

• Myoglobin

• BNP

A nurse knows that unstable angina is considered a:

• Chronic stable condition

• Non–ST-elevation acute coronary syndrome (NSTE-ACS)

• ST-elevation myocardial infarction

• Non-cardiac disorder

During chest pain assessment, the nurse uses PQRST. Which finding strongly suggests unstable angina?

• Pain occurs only during heavy exercise

• Digoxin

• Nitroglycerin

• Warfarin

• Atropine

A client with unstable angina is prescribed beta-blockers. The main purpose is to:

• Increase contractility

• Reduce myocardial oxygen demand

• Increase HR

• Promote vasoconstriction

The ECG of a patient with unstable angina may show:

• Persistent ST-elevation

• T-wave inversion or ST-segment depression

• Normal sinus rhythm only

• Pathologic Q waves

A patient with unstable angina is anxious. The nurse explains the risk is mainly due to:

• Coronary artery spasm only

• Partial rupture or thrombosis of an atherosclerotic plaque
