A child is diagnosed with bacterial conjunctivitis and is prescribed topical antibiotic therapy.

The child's mother asks when he can return to school.

Which response by the nurse would be most appropriate?

"You need to wait until you finish the entire prescription of antibiotic.”.

"Once the drainage is gone, he can go back to school.”.

"You can send him to school this afternoon after his first dose of antibiotic.”.

"He needs to be symptom-free for at least 72 hours.”. — . . .

Answer and Explanation

The Correct Answer is C

Choice A rationale

Although finishing the entire course of antibiotics is crucial for preventing antibiotic resistance and ensuring the complete eradication of the bacteria, it is not the standard criterion for determining when a child can return to school. The infectious period is generally considered to end much sooner after initiating topical treatment.

Choice B rationale

The cessation of eye drainage, or purulent discharge, is a sign of improving infection but is not the sole, definitive indicator for returning to school. The child is generally considered non-infectious and can return to school after a specified period of effective topical antibiotic treatment has been completed.

Choice C rationale

Bacterial conjunctivitis is highly contagious, but contagiousness is rapidly reduced upon starting topical antibiotic treatment. Most school and public health guidelines permit a child to return to school 24 hours after the initiation of topical antibiotic therapy because the risk of transmission is significantly decreased within this timeframe.

Choice D rationale

Requiring a child to be symptom-free for 72 hours is an overly restrictive and generally unnecessary measure for bacterial conjunctivitis managed with topical antibiotics. The standard public health recommendation focuses on the duration of appropriate antibiotic treatment to minimize infectious risk, which is typically 24 hours.

Correct Answer is C

Explanation

Choice A rationale

Testosterone is the primary male sex hormone, an androgen, responsible for the development of male secondary sex characteristics and reproductive tissues. While present in trace amounts in females, it has no direct role in the pulmonary physiology or the production of pulmonary surfactant, which is the critical deficiency leading to respiratory distress syndrome (RDS) in preterm neonates.

Choice B rationale

Somatotropin, also known as growth hormone (GH), is a peptide hormone responsible for stimulating growth, cell reproduction, and regeneration. Its main effects are on somatic growth and metabolism. Although many hormones influence fetal lung maturation indirectly, an altered secretion of somatotropin is not the primary physiological cause for the development of neonatal respiratory distress syndrome.

Choice C rationale

Surfactant is a lipoprotein complex produced by Type II alveolar cells. Its function is to lower the surface tension within the alveoli, preventing their collapse upon expiration. In preterm infants, especially those born before 34 weeks' gestation, the production of adequate amounts of surfactant is often immature or insufficient, leading to widespread atelectasis and the clinical picture of respiratory distress syndrome.

Choice D rationale

Progesterone is a major female sex hormone primarily involved in the menstrual cycle, pregnancy, and embryogenesis. It plays a crucial role in maintaining pregnancy by supporting the uterine lining. While steroid hormones are generally involved in fetal development, altered secretion of progesterone is not the main physiological factor causing the acute alveolar collapse seen in respiratory distress syndrome.
