A 3-week-old infant is admited to the pediatric unit with vomiting and dehydration. The mother describes the infant as having projectile vomiting after eating. She also tells the practical nurse (PN) that the baby is always hungry. Which finding warrants immediate intervention by the PN?
A.
Hyperactive gastric sounds.
B.
Irregular palpable pulse.
C.
Crying without tears.
D.
Underweight for age.
The correct answer and Explanation is :
The correct answer is C. Crying without tears.
Explanation:
In a 3-week-old infant presenting with projectile vomiting and signs of dehydration, immediate assessment and intervention are crucial. Each of the options provided reflects a possible finding in this scenario, but crying without tears is particularly concerning and warrants immediate intervention.
1. Crying without tears: This finding is significant because it indicates dehydration. In infants, tears are produced as a sign of adequate hydration. The absence of tears during crying suggests that the infant is experiencing severe dehydration. Dehydration in infants can rapidly become severe and life-threatening, making it essential to address this symptom promptly. Immediate intervention should focus on rehydrating the infant through appropriate intravenous fluids and addressing the underlying cause of dehydration.
2. Hyperactive gastric sounds: While hyperactive gastric sounds might suggest increased gastrointestinal motility, which could be associated with conditions such as gastroenteritis or other gastrointestinal issues, it is less immediately life-threatening compared to dehydration. However, it is important for the nurse to monitor and assess these sounds in the context of the overall clinical picture.
3. Irregular palpable pulse: An irregular pulse can be a sign of various conditions, including dehydration, electrolyte imbalances, or cardiac issues. While it requires evaluation, it is not as directly indicative of dehydration as the absence of tears.
4. Underweight for age: Being underweight for age may be a concern, but it is a chronic issue that develops over time and is not as immediate as the acute signs of dehydration. The priority is to address the acute dehydration and vomiting before assessing weight issues more comprehensively.
In summary, the absence of tears in crying is a clear indicator of dehydration in infants and requires urgent action to prevent further complications. Immediate intervention should focus on fluid resuscitation and further assessment to manage the infant’s overall condition.
