A child who weighs 25 kg receives a prescription for isoniazid 10 mg/kg/day by mouth once a day.

The bottle is labeled "isoniazid Oral Solution, USP 50 mg per 5 mL.”. How many mL should the nurse administer? (Enter numerical value only.

If rounding is required, round to the nearest whole number.)

Choice A rationale

Covering the lesion with a dressing is not an appropriate action as it will not prevent the transmission of herpes to the newborn. Herpes simplex virus can be transmitted to the neonate during delivery, and covering the lesion does not eliminate the risk.

Choice B rationale

Blood cultures are not indicated for managing active herpes lesions in a client with spontaneous rupture of membranes. This action does not address the immediate risk of transmission of the virus to the newborn.

Choice C rationale

Preparing for a cesarean section is the appropriate action because it reduces the risk of neonatal herpes transmission. Neonatal herpes can lead to severe complications, and a cesarean section is recommended to minimize the risk of exposure to the virus during vaginal delivery.

Choice D rationale

Administering penicillin is not appropriate for treating herpes lesions. Penicillin is an antibiotic effective against bacterial infections, but herpes is caused by a virus. Antiviral medications are required to manage herpes infections.

Choice A rationale

Comparing the temperature of both legs can help identify potential circulatory issues or infections. However, temperature differences are not the most immediate concern when assessing a child with a long-leg cast. Monitoring neurovascular status, including circulation and nerve function, is more critical to ensure there are no complications such as compartment syndrome or impaired blood flow.

Choice B rationale

Monitoring capillary refill of the toes is crucial for assessing the circulatory status of the affected limb. Capillary refill time indicates how well blood is perfusing to the extremities. A delayed capillary refill time can suggest compromised circulation, which could lead to serious complications like tissue ischemia. This assessment helps ensure that the cast is not too tight and that there is adequate blood flow to the toes.

Choice C rationale

Examining for spontaneous movement is important for assessing motor function and ensuring that there is no nerve damage. However, it is not as immediate a concern as circulatory assessment. Spontaneous movement can indicate intact motor function, but circulatory compromise would need to be addressed urgently to prevent tissue damage.

Choice D rationale

Palpating femoral pulses is important for assessing the overall circulation to the lower extremities. However, in the context of a long-leg cast, it is more relevant to directly assess the area distal to the cast (such as the toes) for adequate perfusion. Checking femoral pulses alone does not provide specific information about potential compartment syndrome or tightness of the cast affecting distal circulation.
