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 D
Explanation
Choice A rationale:
Facilitate maternal-newborn interaction. Facilitating maternal-newborn interaction is an important aspect of breastfeeding, but it is not the primary purpose of encouraging breastfeeding immediately after an emergency birth. The primary purpose is to initiate the lactation cycle, allowing the newborn to receive essential colostrum, the first milk rich in antibodies and nutrients, which aids in the development of the newborn's immune system.
Choice B rationale:
Stimulate the uterus to contract. While breastfeeding can stimulate uterine contractions due to oxytocin release, the primary purpose of encouraging breastfeeding in this context is not to contract the uterus but to initiate the lactation cycle for the newborn's benefit.
Choice C rationale:
Prevent neonatal hypoglycemia. Breastfeeding can help prevent neonatal hypoglycemia by providing the newborn with a constant supply of nutrients, but the primary purpose immediately after an emergency birth is to initiate the lactation cycle and provide colostrum, not solely to prevent hypoglycemia.
Choice D rationale:
Initiate the lactation cycle. Initiating the lactation cycle is the correct answer because breastfeeding immediately after birth helps the woman's body start producing milk and provides the newborn with colostrum, essential for their health and development. Colostrum is rich in antibodies and nutrients, offering vital protection and nourishment to the newborn.
Correct Answer is D
Explanation
Choice A rationale:
Explaining how SIDS could have been predicted and prevented might not be appropriate immediately after the loss, as it can come across as insensitive. The focus should be on providing emotional support to the grieving family.
Choice B rationale:
While it's essential to gather information about the circumstances surrounding the infant's death, conducting an in-depth interview immediately might be overwhelming for the parents. Sensitivity and timing are crucial in approaching this aspect of the situation.
Choice C rationale:
Discouraging parents from making a last visit with the infant is highly inappropriate and insensitive. Parents should be allowed to have their final moments with their children and say their goodbyes in a way that brings them comfort and closure.
Choice D rationale:
Making a follow-up home visit to parents as soon as possible after the infant's death is a crucial nursing responsibility. This visit provides an opportunity to offer emotional support, answer any questions the parents might have, and connect them with appropriate resources for coping with their loss. It demonstrates the nurse's ongoing commitment to the family's well-being during this challenging time.
