The school nurse is presenting a seminar to parents about child safety that focuses on the prevention of spinal cord injuries. Which information is most important for the nurse to include in the teaching plan?

Choice A rationale

Zidovudine is a nucleoside reverse transcriptase inhibitor (NRTI). It works by inhibiting the enzyme reverse transcriptase, which is crucial for the replication of retroviruses like HIV. It does not possess any antifungal properties. Fungal infections, such as candidiasis, are often treated with antifungal agents like fluconazole, not antiretroviral drugs.

Choice B rationale

Chorioamnionitis is an intrauterine infection of the chorion and amnion, typically caused by ascending bacteria. It is treated with broad-spectrum antibiotics to address the bacterial etiology. Zidovudine is an antiviral medication specifically targeting the replication of HIV and is ineffective against bacterial infections.

Choice C rationale

Zidovudine works by inhibiting reverse transcriptase, thereby preventing the viral RNA of HIV from being converted into DNA. This mechanism significantly reduces the viral load in the mother and the risk of transplacental transmission to the fetus. This strategy is a cornerstone of preventing perinatal HIV transmission.

Choice D rationale

While zidovudine is a component of highly active antiretroviral therapy (HAART) for managing HIV infection in adults, its primary purpose in the context of labor and delivery is to prevent vertical transmission to the newborn. The treatment regimen for the mother's own HIV complications is a separate, long-term protocol.

Choice A rationale

Rheumatic fever causes inflammation of the heart, joints, and central nervous system. Strict bed rest is necessary to reduce the metabolic demands on the heart. Checkers is an appropriate choice as it is a sedentary activity that provides mental stimulation without requiring physical exertion.

Choice B rationale

A punching bag is an inappropriate toy as it requires significant physical activity and exertion. This would increase the cardiac workload and metabolic rate, which is contraindicated for a child with acute rheumatic fever who is on strict bed rest.

Choice C rationale

A doctor kit involves imaginative role-playing, which can be an appropriate activity. However, it can be physically engaging, depending on how the child plays. Checkers is a better choice as it is purely sedentary, ensuring no physical activity.

Choice D rationale

Play dough can be a suitable toy for a child on bed rest as it requires minimal physical exertion. However, checkers offers a more complex cognitive challenge, which is often more engaging for a 10-year-old and aligns better with their developmental stage.
