Cardiac Marker Quiz: Troponin Or BNP?

1. A patient with renal failure may have elevated BNP without heart failure.

True

False

True

False

3. Which patient population requires careful interpretation of elevated BNP?

Young, obese patients

Patients with advanced renal disease

4. A negative troponin at presentation does not exclude acute MI.

True

False

5. Which marker would be most helpful in monitoring chronic heart failure management?

Troponin I

BNP or NT-proBNP

Myoglobin

CK-MB

6. Troponin elevation in sepsis or septic shock indicates true myocardial infarction.

True

False

7. BNP levels inversely correlate with which cardiac parameter?

Ejection fraction

Heart rate

Blood pressure

Preload

True

False

9. Troponin is composed of three subunits. Which subunit is cardiac-specific?

Troponin C

Troponin I

Troponin T

Both B and C

10. Which condition would cause elevated troponin but normal BNP?

Acute MI with preserved ejection fraction

Chronic heart failure

Pulmonary embolism

Decompensated heart failure

11. Which cardiac marker is most specific for myocardial infarction?

Troponin I

BNP

Myoglobin

CK-MB

12. Serial troponin measurements are typically drawn at what intervals in acute settings?

Every 30 minutes

Every 2-3 hours

Every 6 hours

Once daily

13. BNP is useful for differentiating dyspnea of cardiac versus pulmonary origin.

True

False

14. Which cardiac marker would you expect to rise first in acute MI?

Troponin

Myoglobin

CK-MB

LDH

15. Troponin elevation is specific to myocardial infarction.

True

False

500-1000 pg/mL

Greater than 1000 pg/mL

17. A patient presents with dyspnea and elevated BNP. What is the most likely diagnosis?

Acute coronary syndrome

Heart failure

Pneumonia

Pulmonary hypertension only

18. Which statement about troponin is accurate?

It remains elevated for only 24 hours after MI

Troponin T and I are equally specific for cardiac injury

It can remain elevated for 7-14 days post-MI

It rises within minutes of myocardial injury

19. How long after MI onset does troponin typically become detectable?

Within 1-2 hours

Within 3-4 hours

After 48 hours

20. BNP is released primarily in response to what condition?

Myocardial infarction

Ventricular stretch and increased filling pressure

Pulmonary embolism

Sepsis
