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 D
Explanation
A. Instruct the child to gargle using salt water every 4 hr: Gargling can irritate the surgical site and increase the risk of bleeding.
B. Give the child fluids using a straw: Using a straw creates suction, which can dislodge the clot and cause bleeding.
C. Ask the child to take deep breaths and cough every 30 min: Coughing can increase pressure on the surgical site and lead to bleeding.
D. Apply an ice collar to the child's neck. An ice collar reduces swelling, pain, and the risk of bleeding by promoting vasoconstriction.
Correct Answer is A
Explanation
A. A 15-year-old client who requires an open reduction of a fracture. Minors generally require parental or guardian consent for surgical procedures unless emancipated.
B. A 6-month-old infant requiring IV antibiotics. Informed consent from the guardian is required for medical interventions like IV antibiotics in infants.
C. A 14-year-old client seeking prenatal care. Pregnant minors in many jurisdictions are allowed to consent for their own prenatal care without a guardian's approval.
