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 A
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 B
Explanation
Choice A rationale:
Kimberly and Amanda sharing clay to each make things represents cooperative play, not parallel play. Cooperative play involves interaction and collaboration between children, whereas parallel play involves children playing side by side without interacting.
Choice B rationale:
Brian playing with his truck next to Kristina playing with her truck demonstrates parallel play. In parallel play, children play independently but alongside others, showing interest in what others are doing but without direct interaction.
Choice C rationale:
Adam playing a board game with Kyle, Steven, and Erich represents cooperative play, not parallel play. Cooperative play involves shared activities and collaboration, while parallel play involves independent activities in proximity to others.
Choice D rationale:
Danielle playing with a music box on her mother's lap is an example of solitary play, where a child plays alone without regard to others. Solitary play is common in younger children and is different from parallel play.
Correct Answer is B
Explanation
The correct answer is choiceb. Fetal movement palpated by the nurse-midwife.
Choice A rationale:
A positive pregnancy test is considered a probable sign of pregnancy, not a positive sign. Probable signs are those that strongly suggest pregnancy but are not definitive.
Choice B rationale:
Fetal movement palpated by the nurse-midwife is a positive sign of pregnancy. Positive signs are those that provide definitive evidence of pregnancy, such as fetal heart tones heard by a Doppler device or ultrasound visualization of the fetus.
Choice C rationale:
Braxton Hicks contractions are considered a probable sign of pregnancy. These are irregular, painless contractions that can occur throughout pregnancy but do not confirm pregnancy definitively.
Choice D rationale:
Quickening, or the first feeling of fetal movement by the mother, is a presumptive sign of pregnancy. Presumptive signs are those that the woman experiences and reports, which may suggest pregnancy but are not conclusive.
