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 ["5.6"]
Explanation
To calculate the dosage of amoxicillin for the toddler, first convert the weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The toddler weighs 33 lb, which is approximately 15 kg (33 ÷ 2.2). The prescribed dose is 30 mg/kg/day, so for a 15 kg toddler, the total daily dose is 450 mg (15 kg × 30 mg/kg). This total daily dose should be divided into two doses to be given every 12 hours, resulting in 225 mg per dose (450 mg ÷ 2). Now, using the concentration of the amoxicillin suspension available, which is 200 mg/5 mL, calculate the volume of suspension needed for each dose. For a dose of 225 mg, the volume required is 5.625 mL (225 mg × 5 mL / 200 mg). Rounded to the nearest tenth, the nurse should administer 5.6 mL for each dose.
Correct Answer is B
Explanation
A. Sitting on a nurse's lap leaning forward is a safe position for postural drainage as it promotes drainage from the upper lobes of the lungs.
B. The Trendelenburg position, where the body is laid flat on the back with the feet higher than the head, is contraindicated for infants with cystic fibrosis because it can increase the risk of gastroesophageal reflux and aspiration.
C. The supine position is generally safe but does not facilitate effective postural drainage compared to other positions.
D. Sitting on a nurse's lap leaning backward is safe and can be used for drainage from the anterior lung segments.
