A nurse is preparing to administer erythromycin 50 mg/kg/day in divided doses every 6 hr to an adolescent who is postoperative following surgical removal of a peritonsillar abscess and weighs 40 kg. Available is erythromycin oral solution 200 mg/5 mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["12.5"]
Dose required per day = 50mg/kg/day × 40 kg = 2000 mg/day
Dose per administration = 2000mg4 doses = 500 mg/dose
Volume to administer:
200mg5ml=40mg/ml
500mg40mg/ml=12.5ml/dose

Correct Answer is A
Explanation
A. Monitor temporal artery temperature: Regularly checking the temporal artery temperature can help identify a fever early, allowing for prompt intervention if necessary.
B. Restrain the infant's wrists: Soft elbow restraints (not wrist restraints) are commonly used for infants post-cleft lip repair to prevent them from touching or rubbing the surgical site, which could disrupt the sutures and delay healing.
C. Place the infant in a prone position: After cleft lip surgery, infants should be positioned on their back to avoid pressure on the sutures and reduce the risk of injury.
D. Gently clean the suture line with povidone-iodine solution: It is typically recommended to clean the suture line with a sterile saline solution rather than povidone-iodine, which may irritate the site. Additionally, care should be taken to avoid disturbing the area too much.
