EXAM WITH CORRECT SOLUTIONS.

• 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?

• Reliable; no supplementary oxygen is indicated B. Reliable;

supplementary oxygen should be administered

• Unreliable; no supplementary oxygen is indicated
• Unreliable; supplementary oxygen should be administered -

correct answer- Unreliable; supplementary oxygen should be administered

• 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?

• Septic shock
• Hypovolemic shock 1 / 3

• Significant bradycardia
• Cardiogenic shock - correct answer- Septic shock

• 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?

• During a resuscitation attempt, the team leader orders an

initial dose of epinephrine at 0.1 mg/kg to be given 10. What should the team member do?

• Respectfully ask the team leader to clarify the dose
• Refuse to administer the drug - correct answer- Respectfully

ask the team leader to clarify the dose

• Which of the following is a characteristic of respiratory

failure?

respirations. The seizures stopped a few minutes ago. Which of the following most likely to be abnormal?

• Vascular resistance
• Pulse rate
• Lung compliance
• Control of breathing - correct answer- Control of breathing

• What abnormality is most likely to be present in children with

acute respiratory distress caused by lung tissue disease?

• Decreased oxygen saturation
• Stridor
