febrile and has not been feeling well, with recent onset of lethargy. Assessment reveals the following:
The child is difficult to arouse, with pale color. The child's heart rate is 160/min, respiratory rate is

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

myocardial function?

B. 20 mL/kg of 5% dextrose and 0.2% sodium chloride
C. 20 mL/kg normal saline
D. 10 mL/kg lactated Ringer's - CORRECT ANSWERS-20 mL/kg normal saline
13. An alert toddler presents with a barking cough, moderate stridor, and moderate retractions. The
child's color is pink. What is the most appropriate initial intervention?
A. Obtain a chest radiograph
B. Administer nebulized epinephrine
C. Prepare for a surgical airway
D. Use an epinephrine autoinjector - CORRECT ANSWERS-Administer nebulized epinephrine
14. An 8-year-old child presents with a history of vomiting and diarrhea. The child has 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?
A. Arterial blood gas
B. Serum potassium concentration
C. Glucose
D. A 12-lead ECG - CORRECT ANSWERS-Glucose
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
C. Unreliable; no supplementary oxygen is indicated
D. Unreliable; supplementary oxygen should be administered - CORRECT ANSWERS-
Unreliable; supplementary oxygen should be administered
2. A 3-year-old child was recently diagnosed with leukemia and has been treated with chemotherapy.
The child presents with lethargy and a high fever. Heart rate is 195/min, respiratory rate is 36/min, blood
pressure is 85/40 mm Hg, and capillary refill time is less than 2 seconds. What is the child's most likely
condition?
A. Septic shock
B. Hypovolemic shock
C. Significant bradycardia
D. Cardiogenic shock - CORRECT ANSWERS-Septic shock
3. A 2-week-old infant presents with irritability and a history of poor feeding. Blood pressure is 55/40
mm Hg. What term describes this infant's blood pressure?
A. Hypotensive
B. Normal
