EKG INTERPRETATION EXAM 2025 |124 QUESTIONS
WITH ACCURATE SOLUTIONS
1. Which of the following is true regarding the p waves in this image?
The PR interval is prolonged
There is evidence of left atrial enlargement
There is evidence of right atrial enlargement
The ratio of P:R is less than 1:1
2. A patient presents with symptoms suggestive of right ventricular
hypertrophy. An EKG shows right axis deviation, R > S in V1, and S > R
in V6. Based on these findings, what would be the most appropriate
next step in management?
Initiate treatment for left ventricular failure.
Refer the patient for echocardiography to assess
ventricular function.
Start antiarrhythmic medication.
Monitor the patient without intervention.
3. Which of the following EKG findings is specifically
,associated with hypothermia?
Osborn waves
T-wave inversion
ST-segment
elevation QRS
widening
,4. What is the time frame for the increase and decrease of troponin
levels following a myocardial infarction (MI)?
Increases in 1-2 hours and decreases after 7 days
Increases in 2-3 hours and decreases after 14 days
Increases in 4-5 hours and decreases after 10
days Increases in 3-4 hours and decreases after
21 days
5. Hypokalemia appears on ECG
as... QT interval
shortening
ST-segment depression, decreases in T wave amplitude, &
prominent U waves
Tall, peaked T waves, QRS duration increases, P waves
decrease QT interval prolonged by lengthening of ST
segment
6. A patient presents with symptoms of muscle weakness and
palpitations. An EKG shows ST depression, T wave flattening, and
prominent U waves. What is the most likely underlying electrolyte
disturbance in this patient?
Hyperkalemia
, Hypokalemia
Hypercalcemia
Hyponatremia
7. Which of the following EKG findings is commonly associated with
Chronic Obstructive Pulmonary Disease (COPD)?
Left axis deviation
Low
voltage Tall
R waves
ST elevation
