A nurse is reinforcing teaching about controlling a bleeding episode with a parent of a child who has hemophilia. Which of the following statements by the parent indicates a need for further teaching?

A. Decreased stridor: Stridor is a high-pitched, noisy breathing sound caused by turbulent airflow through a narrowed or partially obstructed airway. In laryngotracheobronchitis, stridor is often present and may worsen with increasing airway obstruction. Therefore, decreased stridor would not be a typical finding associated with airway obstruction in this condition.

B. Increased restlessness: Increased restlessness can be a sign of worsening respiratory distress and impending airway obstruction. As the child struggles to breathe, they may become increasingly agitated and restless, indicating the need for prompt intervention to ensure adequate oxygenation.

C. Decreased heart rate: Decreased heart rate (bradycardia) is not typically associated with airway obstruction in laryngotracheobronchitis. In fact, the heart rate may increase as a compensatory response to hypoxia and respiratory distress.

D. Decreased temperature: Changes in temperature are not typically associated with airway obstruction in laryngotracheobronchitis. The focus of monitoring in this condition is primarily on respiratory distress and signs of worsening airway obstruction.

Convert the child's weight from pounds (lb) to kilograms (kg):

20 lb × (1 kg / 2.20462 lb) ≈ 9.07 kg

Calculate the total daily dose of cefazolin:

Total daily dose = 30 mg/kg/day × 9.07 kg = 272.1 mg/day

Divide the total daily dose into two equal doses:

Each dose = 272.1 mg / 2 ≈ 136.05 mg

Determine the dose per ml using the available oral suspension concentration:

125 mg/5 ml = 25 mg/ml

Calculate the volume of oral suspension needed for each dose:

Volume per dose = Dose per dose / Concentration per ml

≈ 136.05 mg / 25 mg/ml

≈ 5.44 ml

So, the child should receive approximately 5.44 ml per dose of cefazolin oral suspension.
