A 4-year-old child who weighs 44 lbs is diagnosed with Streptococcal Pharyngitis and is prescribed Penicillin. 40 mg/kg/day, twice a day for 10 days. The suspension is written as 400 mg/5 ml. Calculate one dose in mg.
400 mg.
800 mg.
1200 mg.
1600 mg.
The Correct Answer is B
Choice A rationale:
The dosage prescribed for the child is 40 mg/kg/day, twice a day for 10 days. The child weighs 44 lbs, which is approximately 20 kg (1 lb = 0.45 kg). Therefore, the total daily dosage would be 40 mg/kg * 20 kg = 800 mg. This is split into two doses, so each dose would be 400 mg, not 400 mg per 5 ml as in the suspension.
Choice B rationale:
As explained above, the total daily dosage is 800 mg, split into two doses of 400 mg each. The suspension is written as 400 mg/5 ml, so one dose would be 400 mg.
Choice C rationale:
This choice is incorrect because it does not accurately calculate the dosage based on the child's weight and the prescribed dosage regimen.
Choice D rationale:
This choice is incorrect because it suggests a higher dose than what is prescribed. The correct dosage, based on the child's weight and prescription, is 800 mg per day, split into two doses of 400 mg each.

Correct Answer is C
Explanation
Choice A rationale:
Self-monitoring of blood glucose is not recommended primarily because it is a less expensive method of testing. The main reasons for self-monitoring include empowering the child to manage their diabetes, allowing for more frequent monitoring without hospital visits, and facilitating prompt adjustments in insulin or dietary intake.
Choice B rationale:
Self-monitoring of blood glucose can be quite accurate if done correctly. Accuracy depends on proper technique, calibration of the glucometer, and regular maintenance. It is comparable to laboratory testing when performed accurately.
Choice C rationale:
Children with diabetes need to learn to manage their condition as they grow older. Teaching them self-monitoring skills empowers them to take control of their health and make informed decisions about insulin dosages, dietary choices, and physical activity levels.
Choice D rationale:
While parental involvement is essential, self-monitoring of blood glucose is primarily about empowering the child to manage their diabetes. Parents play a supportive role in educating and supervising, but the child's active involvement is crucial for long-term management.
Correct Answer is D
Explanation
Choice A rationale:
Perinatal transmission of HIV can occur not only in the third trimester but also during labor and delivery. It is not limited to the maternal circulation alone.
Choice B rationale:
While needlestick injuries are a potential risk for healthcare workers, perinatal transmission to the newborn does not occur through this route.
Choice C rationale:
HIV is not transmitted through the ingestion of amniotic fluid. The virus can be present in the amniotic fluid, but the main route of transmission to the newborn is during delivery or through breastfeeding.
Choice D rationale:
The correct answer. HIV can be transmitted from an infected mother to her child through breastfeeding if appropriate antiretroviral therapy is not administered. Breast milk can contain the virus, putting the infant at risk of infection. Therefore, in cases where the mother is HIV-positive, formula feeding is recommended to prevent transmission of the virus to the newborn.
