CRCR Certification Exam 2025 | 100 NGN-Style
Practice Questions with Answers & Rationales –
Complete Study Guide
1. (Multiple Choice – Cardiac Anatomy & Physiology)
Which structure of the heart prevents backflow of blood from the ventricles to the atria?
a. Aortic valve
b. Mitral valve
c. Tricuspid valve
d. Semilunar valves
Answer: b, c
Rationale: The mitral valve (left side) and tricuspid valve (right side) prevent backflow from
ventricles to atria during systole.
2. (Multiple Choice – Exercise Prescription)
A patient in cardiac rehabilitation has a resting HR of 72 bpm and a peak exercise HR of 132
bpm. Using the Karvonen formula for 60% target HR, what is the target exercise HR?
a. 102 bpm
b. 114 bpm
c. 120 bpm
d. 108 bpm
Answer: b
Rationale: Target HR = [(HRmax – HRrest) × % intensity] + HRrest = [(132–72) × 0.6] + 72 = 114
bpm.
3. (Select All – Risk Factor Management)
,Which are modifiable cardiovascular risk factors?
a. Hypertension
b. Family history of CAD
c. Smoking
d. Diabetes
e. Age
Answers: a, c, d
Rationale: Hypertension, smoking, and diabetes are modifiable; family history and age are non-
modifiable.
4. (Multiple Choice – Pharmacology)
A cardiac rehab patient is on beta-blockers. Which effect should the nurse anticipate?
a. Increased resting HR
b. Decreased resting HR and BP
c. Increased contractility
d. No effect on exercise tolerance
Answer: b
Rationale: Beta-blockers reduce heart rate, blood pressure, and myocardial oxygen demand.
5. (Scenario – Patient Assessment)
A patient complains of angina during exercise. Which is the priority action?
a. Stop exercise and assess vital signs
b. Encourage continuation at lower intensity
c. Apply heat to chest
d. Document and continue
Answer: a
Rationale: Angina is a warning sign; immediate assessment and cessation of activity are
required.
,6. (Multiple Choice – Rehabilitation Protocols)
Phase II cardiac rehab typically occurs:
a. Inpatient only
b. Outpatient supervised exercise for 3–12 weeks
c. Home exercise with no monitoring
d. Only during emergency hospitalization
Answer: b
Rationale: Phase II focuses on structured outpatient exercise and education for cardiac
patients.
7. (Multiple Choice – Emergency Procedures)
During rehab, a patient becomes unresponsive and pulseless. What is the first action?
a. Begin CPR immediately
b. Call family
c. Administer oxygen
d. Monitor ECG
Answer: a
Rationale: Immediate CPR saves lives in cardiac arrest; emergency services are called
concurrently.
8. (Select All – Patient Education)
Which topics should be included in cardiac rehab education?
a. Diet and nutrition
b. Medication adherence
c. Exercise safety
d. Smoking cessation
e. Hair care
, Answers: a, b, c, d
Rationale: Education focuses on lifestyle, medication, and safety; hair care is unrelated.
9. (Multiple Choice – Exercise Intensity)
Which is the best method to monitor exercise intensity in cardiac rehab?
a. Rating of Perceived Exertion (RPE) scale
b. Sweating frequency
c. Body weight
d. Caloric intake
Answer: a
Rationale: RPE and heart rate monitoring are standard for safe exercise prescription.
10. (Multiple Choice – Pharmacology / Anticoagulation)
Patient on warfarin should avoid which foods to prevent INR fluctuations?
a. Leafy greens high in vitamin K
b. Fish rich in omega-3
c. Lean meats
d. Fruits
Answer: a
Rationale: Vitamin K can counteract warfarin effect, affecting anticoagulation.
11. (Multiple Choice – Risk Factor Management)
Which lab value is most indicative of dyslipidemia?
a. LDL cholesterol >130 mg/dL
b. HDL cholesterol >60 mg/dL
c. Triglycerides <150 mg/dL
d. Fasting glucose 90 mg/dL
Answer: a
