The nurse teaches a pregnant woman about the presumptive, probable, and positive signs of pregnancy.
The woman demonstrates understanding of the nurse's instructions if she states that a positive sign of pregnancy is:.

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.

Choice A rationale:
Soccer involves running, sudden stops, and potential collisions, which can increase the risk of injuries and bleeding in children with hemophilia. While moderate exercise is generally beneficial for individuals with hemophilia, activities with a high risk of trauma, like soccer, should be avoided to prevent bleeding episodes. Therefore, soccer is not the recommended sport for children with hemophilia.
Choice B rationale:
Swimming is a highly recommended sport for children with hemophilia. It is a low-impact exercise that improves cardiovascular health, strength, and flexibility without putting excessive stress on the joints. Swimming also reduces the risk of bleeding episodes, making it a safe and suitable choice for individuals with hemophilia.
Choice C rationale:
Basketball involves rapid movements, jumping, and physical contact, all of which can increase the risk of injuries and bleeding in children with hemophilia. Engaging in sports that involve frequent collisions or physical impact can lead to joint bleeds and other complications in individuals with hemophilia. Therefore, basketball is not the recommended sport for children with hemophilia.
Choice D rationale:
Football, similar to soccer and basketball, involves intense physical contact and rapid movements, making it a high-risk sport for children with hemophilia. Engaging in such activities significantly increases the likelihood of bleeding episodes and injuries. Therefore, football is not the recommended sport for children with hemophilia.
