A child with a bacterial infection is prescribed penicillin. The provider orders 25,000 units/kg/day of penicillin to be given every four hours. The client weighs 56.9 lb. How many units will the nurse administer to the client for one dose? Round to the nearest whole number. Record numerical answer only.

A. Vomiting about 2 hours after feeding: Vomiting in pyloric stenosis typically occurs shortly after feeding, not hours later. This is due to the obstruction at the pylorus that prevents food from moving from the stomach to the small intestine.

B. Vomiting immediately after feeding: Infants with pyloric stenosis often experience forceful, projectile vomiting immediately after feeding. This is due to the narrowing of the pyloric valve, causing food to back up in the stomach and be expelled forcefully.

C. Chronic diarrhea: Diarrhea is not a typical symptom of pyloric stenosis. The condition primarily causes vomiting due to the obstruction at the pylorus, not changes in bowel movements.

D. Refusal to eat: While infants with pyloric stenosis may be irritable and uncomfortable due to vomiting, they usually continue to have a strong appetite and may want to eat frequently despite the vomiting, as they are not absorbing nutrients properly. Refusal to eat is not a hallmark symptom.

A. The infant will need future follow-up for a "nervous" bowel: Colic is not typically associated with a "nervous" bowel. It is marked by excessive crying and discomfort, often with no underlying gastrointestinal issues. No long-term follow-up for a "nervous" bowel is required.

B. Symptoms will decrease if the infant is laid on the back after feedings: The infant should be placed on their back to sleep to reduce the risk of SIDS, but this is not linked to reducing colic symptoms. Colic is associated factors such as digestive discomfort or overstimulation.

C. Formula intake should be doubled to keep the infant from losing weight: Doubling the formula intake is not recommended for managing colic. Overfeeding can worsen discomfort and lead to other issues like reflux. Colic does not typically result in significant weight loss if the infant is feeding appropriately.

D. Colic symptoms will probably fade at 3 months of age: Colic typically peaks around 6 to 8 weeks of age and begins to decrease by 3 to 4 months of age. Most infants outgrow the condition by this time, and the symptoms usually resolve on their own.
