A child with a heart defect is placed on a maintenance dose of Lanoxin elixir. The ordered dose is 0.07mg/kg/day in 2 divided doses. The child weighs 19 pounds. What is the maximum amount of medication that will be given per dose by the nurse?
The Correct Answer is ["0.3"]
Convert weight from pounds to kilograms:
19pounds÷2.2=8.64kg
Calculate the total daily dose:
0.07mg/kg/day×8.64kg=0.6048mg/day
Divide the daily dose into two doses:
0.6048mg/day÷2=0.3024mg/dose
Round off the dose to two decimal places:
0.3024mg≈0.30mg
The maximum amount of medication per dose is 0.3 mg.

Correct Answer is ["A","C","D"]
Explanation
A. Fetal breathing. The biophysical profile assesses fetal breathing movements as one of the components indicating fetal well-being.
B. Fetal neck translucency. This is not part of the biophysical profile; it is typically assessed during first-trimester screening for chromosomal abnormalities.
C. Fetal motion. Fetal movements are another component of the biophysical profile, reflecting the fetal central nervous system integrity and oxygenation.
D. Amniotic fluid volume. The assessment of amniotic fluid volume is crucial in determining fetal well-being and adequate fetal renal function.
E. Fetal gender. Gender is not assessed as part of the biophysical profile; the test focuses on fetal physiological parameters related to well-being.
Correct Answer is D
Explanation
A. Administer Oxytocin IV per MD orders. This may be done after attempting fundal massage to help firm the uterus, but massage is the first step.
B. Notify the healthcare provider. This would be done if the fundus does not respond to massage or if excessive bleeding continues, but not before attempting to firm the fundus.
C. Document the fundal height and consistency. Documentation is important but should occur after addressing the immediate issue of a soft fundus to prevent hemorrhage.
D. Massage the fundus until it firms. The immediate action should be to massage the uterus to promote contraction and reduce bleeding. A soft, spongy uterus indicates uterine atony, which can lead to hemorrhage.
