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 - ANSWER✔✔-C


The majority of cardiac arrests in kids are due to - ANSWER✔✔-Respiratory failure


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 - ANSWER✔✔-C


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)

Copyright ©SOPHIABENNETT 2025 ACADEMIC YEARALL RIGHTS RESERVED. Page 1/84

,A. Machine like murmur


B. Diaphoresis


C. S3 gallop


D. Pulmonary edema - ANSWER✔✔-A




Diaphoresis is r/t adrenergic stimulation


S3 gallop and pulmonary edema are r/t fluid overload


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 - ANSWER✔✔-A- they're all increased


What is the MOST common and what is the LEAST common type of cardiomyopathy in

children? - ANSWER✔✔-Most- dilated


Least- restrictive


A child has been diagnosed with hypertrophic cardiomyopathy. Which of the following

describes this type of myopathy? (cardiac 10)



Copyright ©SOPHIABENNETT 2025 ACADEMIC YEARALL RIGHTS RESERVED. Page 2/84

,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 - ANSWER✔✔-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


What is NOT a goal for treatment for the cardiomyopathies? - ANSWER✔✔-Increasing

preload


What is the action of Milrinone? - ANSWER✔✔-INCREASES intracellular calcium-

increased contractility


Causes vasodilation- decreases after load and PCWP


Which cardiomyopathy needs the most caution with inotropes? - ANSWER✔✔-

Hypertrophic- too much inotropes may burn out the heart muscle and lead to heart

failure

, 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 - ANSWER✔✔-D.


Oncotic pressure is pressure in the vessels pulling water in... with decreased oncotic

pressure the vessels get leaky-




pulmonary edema is leaky


What is cor pulmonale - ANSWER✔✔-R sided heart failure r/t increased pressures in

the pulmonary artery and right ventricle


4 parts of TOF - ANSWER✔✔-VSD


Overriding aorta


Pulmonary stenosis


Right ventricular hypertrophy




Degree of pulmonary stenosis determines how bad TOF is
