MCQs on Angina and GTN Therapy

Angina pectoris is caused by:

• Myocardial inflammation

• Temporary myocardial ischemia

• Complete coronary occlusion

• Valvular regurgitation

Chest pain in angina pectoris is typically:

• Sharp, localized

• Relieved by rest

• Worsened by rest

• Constant and unrelated to exertion

Chronic unstable angina differs from MI because:

• It causes myocardial necrosis

• It resolves with GTN and rest

• It elevates cardiac enzymes

• It shows Q waves on ECG

A patient with angina reports pain radiating to the left arm. This is:

• Unrelated to angina

• A typical characteristic of angina

• A sign of musculoskeletal pain

• Not significant

An ECG during angina typically shows:

• ST elevation

• ST depression

• Tall T waves

• Q waves

A distinguishing ECG feature of MI vs angina:

• T wave inversion in MI

• Q waves in MI

• ST depression in MI

• Sinus bradycardia in MI

Cardiac markers in MI include:

• Troponin I elevation

• Low CK-MB

• Normal LDH

• Normal myoglobin

The action of GTN in angina management:

• Increases preload

• Causes coronary vasodilation

• Increases afterload

• Reduces cardiac output

GTN should be administered:

• Orally swallowed

• Sublingually

• Via IM injection

• Via inhalation

Before administering GTN, the nurse should check:

• Blood glucose

• Blood pressure

• Urine output

• Respiratory rate
