A nurse is assisting with the care of a 1-month-old infant who has neonatal abstinence syndrome and is receiving phenobarbital. Which of the following findings indicates to the nurse that the medication has had a therapeutic effect?
Improved feedings
Restored surfactant
Decreased CNS irritability
Decreased excoriation
The Correct Answer is C
Choice A reason:
Improved feedings can be a positive sign, but it may not directly indicate the therapeutic effect of phenobarbital.
Choice B reason:
Restored surfactant is not directly related to the action of phenobarbital, which is used to manage symptoms of neonatal abstinence syndrome.
Choice C reason:
Phenobarbital is a medication that can help alleviate CNS irritability in infants with neonatal abstinence syndrome. Therefore, a decrease in CNS irritability indicates a therapeutic effect of the medication.
Choice D reason:
Decreased excoriation is not a primary effect of phenobarbital. This medication primarily addresses CNS symptoms associated with neonatal abstinence syndrome.

Correct Answer is ["2.5"]
Explanation
- Convert the infant's weight from pounds to kilograms: 22 Ib / 2.2 = 10 kg
- Calculate the daily dose of azithromycin: 10 mg/kg/day x 10 kg = 100 mg/day
- Calculate the volume of azithromycin oral suspension needed: 100 mg/day / (200 mg/5 mL) = 2.5 mL/day
- Round the answer to the nearest tenth: 2.5 mL/day
- The nurse should plan to administer 2.5 mL of azithromycin oral suspension to the infant.
Correct Answer is C
Explanation
Choice A reason:
Wrapping the extremity loosely with an elastic bandage may provide support but is not specifically aimed at reducing swelling.
Choice B reason:
Applying warm compresses can be beneficial for some types of injuries, but for a sprained wrist, cold compresses are more effective in reducing swelling.
Choice C reason:
This statement is correct. Elevating the extremity above the level of the heart helps to reduce swelling by promoting venous return and reducing blood flow to the affected area.
Choice D reason:
Encouraging active range of motion may be important for rehabilitation, but it is not the initial intervention for minimizing swelling in the first 12 to 24 hours after a sprain.
