A nurse is assessing a 6-month-old infant during a well-child visit.
Which of the following findings should the nurse report to the provider?

Choice A rationale

At 6 months of age, infants typically begin to show a preference for familiar caregivers and may demonstrate stranger anxiety. However, the absence of fear of strangers is a developmental variation and not necessarily a significant red flag requiring immediate reporting. It is not an expected milestone failure at this age.

Choice B rationale

By 6 months of age, an infant should be able to roll from their abdomen to their back, as this milestone typically occurs between 4 and 6 months. Failure to achieve this motor skill may indicate a potential delay in muscle development or neurological function, which warrants a thorough assessment by the provider.

Choice C rationale

A 6-month-old infant is developing fine motor skills, such as raking objects with their fingers, but they are not yet expected to have the pincer grasp to pick up small objects with their fingers. This skill typically develops later, between 9 and 12 months. Therefore, this finding is a normal developmental stage.

Choice D rationale

The ability to sit on the floor unsupported is a milestone typically achieved between 7 and 9 months of age. At 6 months, an infant can often sit with support. Therefore, the inability to sit unsupported is a normal finding for a 6-month-old and does not need to be reported to the provider.

Choice A rationale

Thickening the infant's formula with cereal increases the viscosity of the feeding, making it more difficult for the infant to regurgitate. This physical property of the thickened liquid helps it to remain in the stomach, reducing the frequency of reflux episodes. This is a common non-pharmacological management strategy for gastroesophageal reflux.

Choice B rationale

Avoiding citrus juices is a dietary recommendation for older children and adults with gastroesophageal reflux (GER) to prevent esophageal irritation. However, citrus juices are generally not part of an infant's diet, so this action is not relevant to preventing regurgitation in this age group. An infant's diet is primarily milk-based.

Choice C rationale

Positioning the infant with their head elevated after meals helps to use gravity to keep stomach contents in place and reduce the likelihood of reflux. This position reduces the pressure on the lower esophageal sphincter, making it harder for gastric contents to flow back into the esophagus. This is a key nursing intervention.

Choice D rationale

Placing an infant's head on a soft pillow while sleeping is a significant safety hazard. The use of soft bedding, including pillows, increases the risk of sudden infant death syndrome (SIDS) by causing suffocation or rebreathing of carbon dioxide. This action should be strictly avoided for infants, as per safe sleep guidelines.

Choice E rationale

Antiemetics are medications that prevent vomiting and nausea. While they might be used in some cases, they are not the primary or first-line intervention for preventing regurgitation in infants with GER. The first-line approach involves non-pharmacological measures like feeding adjustments and positioning, which are safer and often more effective.
