The healthcare provider (HCP) prescribes amoxicillin 500 mg PO every 8 hours for a child who weighs 77 pounds. The available suspension is labeled, "Amoxicillin Suspension 250 mg/5 mL. The recommended maximum dose is 50 mg/kg/24 hour. How many mL should the nurse administer in a single dose based on the child's weight? (Enter the numerical value only. If rounding is required, round to the whole number.)
The Correct Answer is ["10"]
Calculation:
Desired dose = 500 mg.
Available concentration = 250 mg / 5 mL
= 50 mg/mL.
- Calculate the volume to administer in milliliters (mL).
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 500 mg / 50 mg/mL
= 10 mL.

Correct Answer is {"dropdown-group-1":"A"}
Explanation
Rationale for Correct Choice
- Interrupting feeding if the infant raises their eyebrows: Infants with a submucous cleft palate are at increased risk for aspiration due to abnormal palate structure. Observing subtle cues, such as raising eyebrows or coughing, and pausing the feeding helps prevent formula or saliva from entering the airway.
Rationale for Incorrect Choices
- Waiting until the end of each feeding to burp: Delaying burping can increase the risk of aspiration and discomfort, as air swallowed during feeding may cause regurgitation or vomiting in infants with cleft palate.
- Placing the infant in a reclining position at 45 degrees: Reclining can worsen the risk of aspiration. The infant should be positioned upright or semi-upright to facilitate safe swallowing and reduce airway compromise.
Correct Answer is D
Explanation
Rationale:
A. Keep house pets away from the food preparation area: While maintaining hygiene around pets is good practice, rotavirus is primarily transmitted via the fecal-oral route between humans, so pet contact is not a major factor in prevention.
B. Use only lactose-free formulas: Lactose-free formulas address lactose intolerance but do not prevent rotavirus infection. Formula type has no impact on viral transmission.
C. Avoid feeding infants fresh fruits: Fresh fruits are generally safe and do not increase the risk of rotavirus infection if proper hand hygiene and food handling practices are followed. Avoiding fruits is unnecessary.
D. Wash hands before any food preparation: Rotavirus is highly contagious and spreads via the fecal-oral route. Proper handwashing before preparing or feeding food is a key preventive measure to reduce the risk of infection in infants.
