What assessment should a nurse perform for a neonate born at 42 weeks gestation weighing 9 lbs?

In assessing a neonate born at 42 weeks gestation who weighs 9 lbs, evaluating for a clavicle fracture is particularly relevant due to the increased risk associated with higher birth weights and prolonged gestation. Infants delivered with a larger size, often referred to as macrosomia, are at a greater risk for birth injuries during delivery, including fractures. A clavicle fracture can occur during a difficult birth, especially if there are complications such as shoulder dystocia, which can happen more frequently with larger infants.

Recognizing the signs of a clavicle fracture involves observing for asymmetric arm movement, a pronounced "clavicular click" upon movement, or a palpable step-off at the fracture site. Prompt identification and management are essential to prevent complications and facilitate appropriate care.

The other options listed pertain to different assessments that may not be as immediate or relevant for a neonate of this gestational age and weight. For example, facial paralysis is associated more with certain birth injuries but is less directly related to the specific risk factors presented by a late-term, heavier baby. Ophthalmia neonatorum involves assessing for eye infections resulting from exposure during delivery, which is not specifically linked to gestational age or weight in this context. Erythema toxic
