A nurse in a clinic is assessing a 9-month-old infant.
Which of the following findings requires further intervention?

The correct answer is Choice B.

Choice B rationale

Administering an intravenous antibiotic is the priority action for a child with suspected bacterial meningitis. Early administration of antibiotics is crucial to treat the infection and prevent complications such as brain swelling and seizures.

Choice A rationale

Obtaining blood cultures is important for identifying the causative organism, but it should be done immediately before or concurrently with the administration of antibiotics.

Choice C rationale

Preparing the child for a lumbar puncture is necessary for diagnosing meningitis, but it should not delay the administration of antibiotics.

Choice D rationale

Placing the child in isolation is important to prevent the spread of infection, but it is not the immediate priority over administering antibiotics.

The correct answer is Choice A.

Choice A rationale

Projectile vomiting is a hallmark symptom of pyloric stenosis. It occurs due to the obstruction at the pylorus, causing forceful expulsion of stomach contents. This symptom typically appears in infants between 3 to 6 weeks of age.

Choice B rationale

A rigid abdomen is not a typical symptom of pyloric stenosis. It may indicate other abdominal issues, such as peritonitis or bowel obstruction.

Choice C rationale

Red currant jelly stools are associated with intussusception, not pyloric stenosis. Intussusception involves the telescoping of one part of the intestine into another, leading to bowel obstruction and characteristic stool appearance.

Choice D rationale

Distended neck veins are not related to pyloric stenosis. This symptom is more commonly associated with cardiac conditions or severe respiratory distress.
