an oncologist to determine the chemotherapeutic regimen - ANSWER//Obtain vascular
access and administer 20 mL/kg of isotonic crystalloid over 5 to 10 minutes

reveals an unresponsive child with intermittent apnea and mottled color. Heart rate is
166/min, respiratory rate is now being supported with bag-mask ventilation, capillary
refill time is 5 to 6 seconds, and temperature is 102°F (38.9°C). What is the best method
of establishing immediate vascular access? A. Two providers may attempt peripheral
vascular access twice each
B. Three providers may attempt peripheral vascular access once each

the following vital signs: heart rate 168/min, respiratory rate 15/min, blood pressure
9060 mm Hg, and temperature 98.6°F (37°C). The child's capillary refill time is 4
seconds. After 2 IV boluses of normal saline (20 mL/kg each), the child's vital signs are
now as follows: heart rate 130/min, respiratory rate 16/min, blood pressure 94/62 mm
Hg, capillary refill 2 seconds, and temperature 98.6°F (37°C). The child's urine output is
1 to 2 mL/kg in the past hour. The child is still lethargic. What diagnostic tests or
information should be obtained first?

84/60 mm Hg, and his capillary refill time is 3 seconds. What is the most appropriate
intervention?

bolus of 20 mL/kg of normal saline. On reevaluation the child remains anxious, with a
heart rate of 140/min, a blood pressure of 84/54 mm Hg, and a capillary refill time of 4
seconds. What describes this patient's condition?
A. Hypotensive shock
B. Compensated shock
C. No longer in shock
D. Cardiogenic shock - ANSWER//Compensated shock
9. An 8-year-old child had a sudden onset of palpitations and light-headedness. At the
time of evaluation the child is alert. His respiratory rate is 26/ min, and his blood
pressure is 104/70 mm Hg. A cardiac monitor is applied, and the rhythm below is noted.
What is the most appropriate initial intervention?
A. Provide synchronized cardioversion at 0.5 to 1 J/kg
B. Attempt vagal maneuvers
C. Administer adenosine 0.1 mg/kg over 5 minutes D. Administer amiodarone 5 mg/kg
over 20 minutes - ANSWER//Attempt vagal maneuvers
10. A 10-year-old child had a sudden witnessed cardiac arrest and received immediate
bystander CPR and defibrillation within 3 minutes. He had a return of spontaneous
circulation. The child remains unresponsive and has an advanced airway in place.
There is no history of trauma or signs of shock. What is the target range for oxygen
saturation for this child?
A. 92% to 100%
B. 92% to 99%
C. 94% to 99%
D. 94% to 100% - ANSWER//94% to 99%
11. A 3-month-old infant with bronchiolitis is suctioned to remove upper airway
secretions. The infant's heart rate decreases from 155/min to 65/min as shown below.
The infant remains alert, with easily palpable pulses. Capillary refill time is 1 second.
What is the most appropriate initial intervention?
A. Administer oxygen and ensure adequate ventilation; be prepared to intervene further
if heart rate does not increase
B. Establish IV/IO access and administer epinephrine 0.01 mg/kg IV
Establish IV/IO access and administer atropine 0
1. A 5-year-old child presents with lethargy, increased work of breathing, and pale color.
The primary assessment reveals that the airway is open and the respiratory rate is
30/min, with crackles heard on auscultation. The cardiac monitor shows sinus
tachycardia at a rate of 165/min. The pulse oximeter displays an oxygen saturation of
95% and a pulse rate of 93/min. On the basis of this information, which of the following
provides the best interpretation of the oxygen saturation of 95% by pulse oximetry?
A. Reliable; no supplementary oxygen is indicated B. Reliable; supplementary oxygen
should be administered
