Which finding might be seen in a neonate suspected of having an infection?

Appeared in: WCL Staff Nurse - 2019

Explanation

Decreased temperature (hypothermia) is a significant and common sign of sepsis in neonates.
This paradoxical response occurs because newborns have an immature thermoregulatory system and may be unable to generate a fever when fighting an infection.
While temperature instability (both high and low) is a hallmark of neonatal infection, a drop in temperature is a critical warning sign that requires immediate attention.

Option A: Flushed cheeks are typically a sign of vasodilation associated with fever or being too warm. In neonatal sepsis, poor perfusion often leads to pallor or mottling, not flushing.
Option B: While an increased temperature (fever) can occur in neonatal sepsis, it is a less common and less reliable sign than hypothermia. Relying solely on the presence of fever can lead to a missed or delayed diagnosis.
Option D: Systemic infection in a neonate consumes significant energy and typically leads to central nervous system depression, resulting in lethargy, hypotonia, and decreased activity.

Clinical Relevance

Nursing practice connection: Knowing Signs of Neonatal Sepsis helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
A nurse must perform frequent and accurate temperature assessments (usually axillary) on at-risk neonates, recognizing that a low temperature is as concerning, if not more so, than a high one.
Patient Safety: Failure to recognize hypothermia as a sign of sepsis can delay crucial interventions like obtaining blood cultures and starting antibiotics, leading to increased morbidity and mortality.
What if... the neonate was also premature? The risk and presentation of hypothermia as a sign of sepsis would be even more pronounced due to less developed thermoregulation and lower brown fat stores.

How to Approach the Question

First, identify the specific patient population in the question: a 'neonate'. This is the most important clue.
Recall the unique physiological characteristics of a newborn, especially their immature immune and thermoregulatory systems.
Evaluate each option based on this specific neonatal physiology. Ask yourself, 'How does a newborn's body typically respond to a major stressor like infection?'
Eliminate options that describe a response more typical of an older child or adult, such as a consistent, high fever.
Select the option that reflects the neonate's unique, and sometimes paradoxical, response to illness, which in this case is often a drop in temperature.
