A nurse is assessing a newborn for manifestations of a large patent ductus arteriosus. Which of the following findings should the nurse expect?
Weak pulses
Chronic hypoxemia
Systolic murmur
Cyanosis with crying
The Correct Answer is C
Rationale:
A. Weak pulses are not typically associated with a large patent ductus arteriosus. Instead, bounding pulses may be observed due to increased blood flow to the lower extremities.
B. Chronic hypoxemia may occur in some cases of patent ductus arteriosus, but it is not a specific manifestation typically associated with this condition.
C. Systolic murmur is a common finding in newborns with a large patent ductus arteriosus. This murmur is often continuous with the second heart sound and may be heard best at the left upper sternal border.
D. Cyanosis with crying is not typically associated with patent ductus arteriosus. Cyanosis may occur in other cardiac defects but is not a specific finding for patent ductus arteriosus.

Correct Answer is D
Explanation
A. Ibuprofen is not recommended for infants younger than 6 months due to the risk of adverse effects, including kidney impairment.
B. Positioning the infant on the abdomen can place pressure on the surgical site and increase the risk of disrupting the incision. Infants should be positioned on the back or side after cleft lip repair.
C. Offering a pacifier is avoided after cleft lip surgery because sucking can place stress on the incision and interfere with healing.
D. Encouraging the parents to rock the infant is appropriate. Gentle comforting measures help soothe the infant without putting pressure on the surgical site and support bonding and emotional comfort.
Correct Answer is ["5.3"]
Explanation
To calculate the dosage of acetaminophen for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds.
The child weighs 28 lb, which is approximately 12.7 kg (28 / 2.2 = 12.7).
The prescribed dose is 10 mg/kg, so the child's dose is 127 mg (10 mg/kg 12.7 kg).
Now, using the concentration of the available medication, which is 120 mg/5 mL, you can calculate the volume of medication needed.
For 120 mg of acetaminophen, 5 mL of liquid is required, so for 127 mg, it would be 5 mL (127 mg / 120 mg) = 5.29 mL.
Therefore, the nurse should administer 5.3 mL, rounding to the nearest tenth as instructed.
