A nurse is assessing a 4-month-old infant during a well-baby visit. For which of the following findings should the nurse notify the provider?

A. Vomiting is a common symptom of NEC. It can occur due to the inflammation and necrosis in the intestines, which disrupt normal digestion and absorption. In NEC, the vomit may also contain bile or even blood, depending on the severity of the condition.
B. Tachypnea, or rapid breathing, can be observed in infants with NEC, though it is not the most specific sign. Tachypnea may result from the body's response to systemic infection or sepsis, which can occur with NEC. However, tachypnea alone is not as directly indicative of NEC compared to other signs.
C. Hypertension (high blood pressure) is not a typical finding associated with NEC. The condition is more commonly linked with signs of gastrointestinal distress and systemic infection. Hypertension is less commonly observed in this context and is not a primary indicator of NEC.
D. A rounded abdomen can be a sign of abdominal distension, which is a key finding in NEC. Abdominal distension occurs due to the accumulation of gas and fluid in the intestines as a result of inflammation and necrosis. This can lead to a visibly swollen or rounded appearance of the abdomen.

A. A child might feel more anxious without a parent present. The parent's presence can provide comfort and support.
B. Overly detailed explanations might increase anxiety. Providing simple, age-appropriate information just before the procedure is more effective.

C. The playroom is associated with fun activities. Performing a medical procedure in this environment can create negative associations.
D. Applying a topical anesthetic cream before the procedure can significantly reduce pain and discomfort during venipuncture, providing atraumatic care.
