A nurse is caring for a toddler who has laryngotracheobronchitis. For which of the following findings should the nurse monitor to detect airway obstruction?

Decreased stridor

Increased restlessness

Decreased heart rate

Decreased temperature

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is C

Explanation

A. "Your child's diet should be high in carbohydrates & proteins with no restriction of fats."

This statement is not entirely accurate. While it's true that children with cystic fibrosis often require a diet that is higher in calories and protein to support growth and weight gain, there is typically a need to restrict fat intake. Pancreatic insufficiency, which is common in cystic fibrosis, can lead to malabsorption of fats and fat-soluble vitamins. Therefore, a dietitian may recommend enzyme replacement therapy and a diet that is moderate in fat but high in calories and protein.

B. "Limit your child's intake of sodium to avoid complications."

This statement is not accurate. Cystic fibrosis can lead to excessive loss of salt in sweat, which can contribute to dehydration and electrolyte imbalances. Therefore, limiting sodium intake can cause electrolyte disturbances.

C. "A pigeon-shaped chest might become evident as the disease progresses."

This statement is accurate. Cystic fibrosis can cause chronic lung infections and inflammation, leading to structural changes in the chest over time. One common manifestation is a barrel-shaped or "pigeon-shaped" chest, which can occur as the disease progresses. This may result from hyperinflation of the lungs due to air trapping and chronic respiratory compromise.

D. "Administer a bronchodilator to the child after chest percussion therapy."

This statement is not necessarily accurate or applicable to all cases. Bronchodilators are medications used to help relax and open the airways in conditions such as asthma or chronic obstructive pulmonary disease (COPD). While bronchodilators may be part of the treatment regimen for some individuals with cystic fibrosis, their use after chest percussion therapy would depend on the individual's specific respiratory symptoms and treatment plan. It's important for the parents to follow the healthcare provider's instructions regarding medication administration.

Correct Answer is ["5.4"]

Explanation

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.
