Coarctation of the aorta demonstrates few symptoms in newborns. What is a important assessment to the nurse make on all newborns to help reveal this condition?
Recording an upper extremities,
Assessing for the presence of femoral pulses
Observing for excessive crying
Auscultating for a cardiac murmur
The Correct Answer is A
A. Recording an upper extremity blood pressure (in the arms) compared to a lower extremity blood pressure (in the legs) can help reveal coarctation of the aorta, as the condition often results in higher blood pressure in the upper body and lower pressure in the lower body.
B. Assessing for femoral pulses is important but may not reveal coarctation of the aorta unless there is significant obstruction.
C. Excessive crying is not a specific indicator of coarctation of the aorta.
D. While a cardiac murmur can be associated with various heart conditions, it is not the most definitive assessment for coarctation of the aorta.

Correct Answer is ["3.6"]
Explanation
To calculate the dosage of digoxin for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 66 pounds, which is approximately 30 kilograms (66 ÷ 2.2). The prescribed dose is 12 micrograms per kilogram per day, which equals 360 micrograms per day (12 mcg × 30 kg). Since the dose is divided every 12 hours, the child should receive 180 micrograms every 12 hours. The digoxin elixir is available at a concentration of 0.05 mg/mL, which is the same as 50 micrograms per milliliter. To find out how many milliliters to administer per dose, divide the dose in micrograms by the concentration: 180 mcg ÷ 50 mcg/mL equals 3.6 mL.
