CCRN tricky practice questions 2024/2025 EXAM QUESTIONS
AND CORRECT ANSWERS ALREADY GRADED A+ PROFESSOR
VERIFIED
1. How do young children respond to decreased cardiac output? (cardiac 3)
A. SV and HR are increased
B. SV and HR are decreased
C. SV stays the same and HR is increased
D. SV is decreased and HR is increased: C
2. The majority of cardiac arrests in kids are due to: Respiratory failure
3. Adrenergic stimulation is one of the compensatory mechanisms used when
cardiac output fails. Which of the following is a result of adrenergic
stimulation? (cardiac 6)
A. Longer diastolic period
B. Blockage of the release of norepinephrine and epinephrine
C. Increased myocardial oxygen consumption
D. Increased systemic blood flow: C
,4. Jose is a 19 m/o with congestive heart failure secondary to cardiomyopathy.
Which of the following manifestations would the nurse NOT expect to find?
(cardiac 7)
A. Machine like murmur
B. Diaphoresis
C. S3 gallop
D. Pulmonary edema: A
Diaphoresis is r/t adrenergic stimulation
S3 gallop and pulmonary edema are r/t fluid overload
5. Which of the following is NOT true r/t L sided heart failure? (cardiac 8)
A. PAP, PCWP and CVP are all decreased
B. During systole, the L ventricle does not completely empty
C. There is a back flow of blood from the left ventricle to the left atrium
D. There is decreased contractility: A- they're all increased
6. What is the MOST common and what is the LEAST common type of
cardiomyopathy in children?: Most- dilated
Least- restrictive
7. A child has been diagnosed with hypertrophic cardiomyopathy. Which of
the
following describes this type of myopathy? (cardiac 10) A.
Fibrosis and scarring lead to poor contractile movement
B. It is congenital
C. It is a congestive cardiomyopathy
,D. There is a decrease in size and capacity of the ventricles: D. Hypertrophic is
a myopathy that leads to decreased ventricular space because the myocardial
muscle is so large
Restrictive is congenital where there is poor contractile movement r/t fibrosis and
scarring
Dilated is congestive because stasis of blood can occur in the chambers
8. What is NOT a goal for treatment for the cardiomyopathies?: Increasing
preload
9. What is the action of Milrinone?: INCREASES intracellular calcium- increased
contractility
Causes vasodilation- decreases after load and PCWP
10. Which cardiomyopathy needs the most caution with inotropes?:
Hypertrophic- too much inotropes may burn out the heart muscle and lead to
heart failure
11. Which of the following is TRUE concerning pressures in pulmonary
edema? (cardiac 14)
A. Increase in both oncotic and pulmonary capillary pressure
B. Decrease in both
C. Increase in oncotic pressure and decrease in pcp
D. Decrease in oncotic pressure and an increase in pcp: D.
Oncotic pressure is pressure in the vessels pulling water in... with decreased
oncotic pressure the vessels get leaky-
pulmonary edema is leaky
12. What is cor pulmonale: R sided heart failure r/t increased pressures in the
pulmonary artery and right ventricle
13. 4 parts of TOF: VSD
Overriding aorta
Pulmonary stenosis
Right ventricular hypertrophy
, Degree of pulmonary stenosis determines how bad TOF is
14. In a patient with TOF, what structural variance is present in a hyper
cyanotic spell? (cardiac 16)
A. decrease in pulmonary blood flow
B. Increase in left to right shunting
C. Communication between the atria D. Temporary cessation of shunting: A.
15. What would be seen in compensated shock? (cardiac 19)
A. Hypotension
B. Cold clammy skin
C. Jaundice
D. Ecchymosis and petechiae: B.
Hypotension is uncompensated and Ecchymosis and petechiae occur when the
clotting factors are alerted in uncompensated shock
16. Which of the following is NOT present in hypovolemic shock? (cardiac 21)
A decreased preload
B decreased afterload
C no change in contractility
D Decreased cardiac output: B
17. What is the most common heart defect in children?: VSD
18. Alex is a 10 month old with AV canal. After surgical correction, Alex
experiences a serious complication where his blood pressure and heart
rate drop and pulmonary artery pressure increases. All of the following
could be used to manage this complication EXCEPT (cardiac 23):
A. Administration of nitric oxide
B. Hyperventilation
