A nurse is teaching a parent of a child about the potential risk factors of strabismus. Which of the following statements given by the parent indicates that further teaching is needed?

A. High levels of cerebrospinal fluid (CSF): Spina bifida is a neural tube defect involving incomplete closure of the vertebral column rather than abnormal CSF production. Elevated CSF levels are not a defining feature and are not used as a screening indicator. CSF abnormalities are more relevant to hydrocephalus assessment.

B. Increased intracranial pressure (ICP): Elevated ICP may occur secondary to associated conditions such as hydrocephalus, but it is not an initial or direct sign of spina bifida. The defect itself is identified by spinal and cutaneous findings. ICP changes develop later if complications arise.

C. Indications of infection: Infection is a potential complication if neural tissue is exposed, but it is not an initial indicator prompting suspicion of spina bifida. Early recognition relies on visible spinal or skin markers. Infection suggests a secondary problem rather than the congenital defect.

D. Presence of a small dimple and a tuft of hair over the lower lumbar region: Cutaneous stigmata such as a sacral dimple, hair tuft, or discoloration are classic indicators of underlying spinal dysraphism. These findings warrant further evaluation for spina bifida occulta. They are key clues during newborn and infant assessment.

A. "We will avoid exposing our baby to secondhand smoke and sick individuals.": Avoiding smoke and sick contacts reduces the risk of upper respiratory infections, which are a major contributing factor to otitis media. This reflects correct understanding of preventive measures.

B. "Our child can continue to receive breastfeeding.": Breastfeeding provides immunologic protection through antibodies that help reduce the incidence of otitis media, making this a correct preventive strategy.

C. "We do not need to finish the prescribed antibiotic once the baby seems better to avoid unnecessary medication.": Not completing the full course of antibiotics can lead to incomplete eradication of bacteria, recurrent infections, and antibiotic resistance. This statement indicates a misunderstanding that requires further teaching.

D. "We will always feed our baby in an upright position to help prevent ear infections.": Upright feeding reduces fluid accumulation in the middle ear, which helps prevent OM, reflecting proper parental understanding of preventive practices.
