A nurse is caring for a child with hemophilia.

Which of the following interventions should be included in your plan of care and teaching to the caregivers? Select all that apply.

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.

Choice A rationale

An Apgar score of 7 at 1 minute indicates that the infant is experiencing only mild difficulty with the transition to extrauterine life, and an Apgar score of 9 at 5 minutes indicates a successful adaptation. Severe distress requiring immediate, aggressive resuscitation is suggested by scores of 0 to 3, which is not the case here.

Choice B rationale

An Apgar score of 7 at 1 minute and a score of 9 at 5 minutes is the most common pattern, indicating the newborn is successfully adjusting to extrauterine life with minimal or no difficulty. The score of 7 suggests some minor, non-life-threatening depression at birth that resolved quickly by the 5-minute assessment.

Choice C rationale

Moderate difficulty and the potential need for some intervention, such as oxygen or tactile stimulation, would typically be suggested by an Apgar score in the range of 4 to 6 at 1 minute. The score of 7 suggests a better initial status than moderate difficulty, and the score of 9 confirms a successful transition.

Choice D rationale

The Apgar score is primarily an assessment of a newborn's cardiorespiratory and neurological status during the immediate transition phase, and while it is generally a good indicator of immediate neonatal well-being, it is a poor predictor of long-term neurologic future outcomes. Low scores persisting at 5 minutes are more concerning for future outcomes.
