MULTIPLE CHOICE
1. Central cyanosis is associated with which phenomena?
a. Decreased peripheral blood flow
b. Desaturation of arterial blood
c. Reduced hemoglobin of 15 g/dL
d. Permanent cerebral hypoxia
ANS: B
Cyanosis is visible when hemoglobin is reduced by 5 g per 100 mL of
blood. C yanosis associated with desaturation of arterial blood is called
central cyanosis. Peripheral cyanosis is a condition in which cyanosis
exists but the child has normal arterial oxygen saturation.

2. What is the initial treatment for hypoxia, acidosis, or hypothermia?
a. Vasopressin
b. Bronchodilators
c. Oxygenation and ventilation
d. Hydration
, ANS: C
Bradycardia can result from hypoxia, acidosis, or hypothermia.
Bradycardia is defined as a cardiac rate less than 100 beats/min for an

3. What is the initial setting on a manual defibrillator for a patient older than
1 year?
a. 100 joules
b. 360 joules
c. 2 joules/kg
d. 4 joules/kg
ANS: C
On a manual defibrillator, the initial dose of electricit y is 2 joules/kg.
If using an automated external defibrillator, this should onl y be used
for children older than 1 year. Immediately after the shock,
