CCT Exam Questions & Answers 2026 | High-Yield Review |
Graded A+
1. What does chronotropic mean?
Increase conduction velocity
Increase heart strength
Increase heart rate
2. Describe the significance of the absolute refractory period in cardiac
physiology.
The absolute refractory period is when the heart is fully relaxed and
filling with blood.
The absolute refractory period is the time when the heart valves are
closing.
The absolute refractory period allows for rapid heart rate increases
during exercise.
The absolute refractory period prevents the heart from being
stimulated again, ensuring proper timing of heartbeats.
3. What is the formula commonly used to calculate maximal heart rate?
240 minus age
200 minus age
220 minus age
180 minus age
4. A patient presents with a myocardial infarction and is treated with TPA. What
is the expected outcome of administering this thrombolytic agent?
, Strengthening of heart valve function and prevention of arrhythmias.
Increased heart rate and improved cardiac output.
Decreased blood pressure and reduced heart workload.
Dissolution of the blood clot and restoration of blood flow to the
heart muscle.
5. A blood pressure is taken at which artery?
Brachial
Popliteal
Femoral
Carotid
6. Digitalis is one of the primary drugs used to treat CHF because
It decreases blood pressure
It increases myocardial contractility & cardiac output
It decreases cholesterol
Is a vasodilator
7. Which lead is typically associated with a predominantly negative QRS
complex in a standard EKG?
I
II
V1
V5
,8. A client has heart failure and is prescribed Lasix. The nurse is aware the
fuorsemide ( Lasix) is what kind of drug?
Loop Diuretic
Potassium Sparing Diuretic
Thiazide diuretic
Osmotic Diuretic
9. Refer to the previous diagram. Which of the following is primarily responsible
for phase 2 of the fast response myocyte?
Ca+2 efflux
Ca+2 influx
Na+ influx
K+ influx
10. Somatic tremors is artifact made by:
improper ground electrode
stress loops not secure
elecftrical appliance interference
electrodes being placed over the muscle
11. What specific changes in an EKG are indicative of ischemia?
ST segment depression or elevation
Prolonged QT interval
Normal sinus rhythm
T wave inversion
, 12. What structure is the pericardium normally attached to?
The lungs
The heart
The diaphragm
The aorta
13. The Bruce Protocol increases intensity every___minutes.
2
3
4
5
14. What is the term used to describe the difference between systolic and
diastolic blood pressure?
Pulse Pressure
Mean Arterial Pressure
Double Product
Cardiac Output
15. Blood flow in the capillaries is steady (not pulsating) because:
mean arterial pressure averages blood pulsation out
elastic connective tissue in arteries absorbs most of the pulsation
peripheral resistance is greatest at a capillary bed.
