CORRECT ANSWERS




1. A 5-year-old child presents with lethargy, increased work of breathing, and pale color. The primary
r r r r r r r r r r r r r r r r




assessment reveals that the airway is open and the respiratory rate is 30/min, with crackles heard on
r r r r r r r r r r r r r r r r r




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
