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 - ✔✔✔✔-Unreliable; supplementary
oxygen should be administeredANS2. A 3-year-old child was recently diagnosed with leukemia and has

2 seconds. What is the child's most likely condition?
A. Septic shock
B. Hypovolemic shock
C. Significant bradycardia
D. Cardiogenic shock - ✔✔✔✔-Septic shockANS3. A 2-week-old infant presents with irritability and a

month-old infant with bronchiolitis is intubated for management of respiratory failure. During transport,
the infant develops bradycardia with a heart rate of 60/min, and the infant's oxygen saturation
