Chapter 21: The Child with Respiratory Dysfunction - Nurselytic

Correct Answer: A

Rationale: Antibiotics are essential for treating bacterial pneumonia like staphylococcal pneumonia. Frequent complete assessments are unnecessary if respiratory status is monitored, antitussives are used sparingly to allow secretion clearance, and fluid monitoring prevents dehydration, not heart failure.

Correct Answer: B

Rationale: Chemotherapy with drugs like isoniazid, rifampin, and pyrazinamide is the cornerstone of TB management in children, administered for 2 months daily and then 4 months biweekly. Skin testing aids diagnosis, while rest and hydration support but are secondary to drug therapy.

Correct Answer: C

Rationale: A unilateral foul-smelling nasal discharge with sneezing suggests a foreign body causing local irritation and obstruction. Allergies cause bilateral clear discharge, pharyngitis lacks nasal discharge, and nasopharyngitis produces bilateral mucous discharge.

Correct Answer: B

Rationale: Monitoring pulse oximetry is critical to assess oxygenation in ARDS, guiding respiratory support. Fluids are given parenterally to maintain hydration, seizures are not typical in ARDS, and a high-protein diet is not specifically beneficial compared to balanced nutrition.

Correct Answer: B

Rationale: Monitoring arterial blood gases is essential for CO poisoning, as pulse oximetry is unreliable due to normal PaO2 levels. High-flow oxygen should be administered immediately, not only if distress or cherry-red lips (a late sign) appear, to displace CO from hemoglobin.
