A nurse is assessing a 9-month-old infant who has gastroenteritis. Which of the following findings should the nurse identify as a manifestation of severe fluid volume deficit?

A. Intake and output: The infant has not fed in 8 hours and has only had 1 wet diaper during this time, which is concerning for dehydration or inadequate intake. The decreased output requires immediate follow-up to prevent further dehydration and assess fluid needs.
B. Heart rate: The heart rate of 180/min is elevated for an infant, potentially indicating dehydration, fever, or respiratory distress. Tachycardia can also signify compensation for hypoxia.
C. Respiratory rate: A respiratory rate of 60/min is elevated for an infant and indicates respiratory distress, compounded by retractions and diminished lung sounds in the right lobes.
D. Bowel sounds: Active bowel sounds in all four quadrants are a normal finding and do not indicate an acute issue.
E. Mucous membranes: While dry mucous membranes confirm dehydration, they are not the highest priority compared to respiratory distress or oxygen saturation.
F. Weight: Weight loss from 9 lb to 8 lb 8 oz is concerning for chronic dehydration or inadequate nutrition, but it does not require immediate action compared to acute respiratory and oxygenation issues.
G. Retractions: Moderate substernal and intercostal retractions are indicative of respiratory distress. This requires immediate follow-up to assess the severity of the distress and initiate appropriate interventions, such as supplemental oxygen or further evaluation.
H. Lung sounds: Diminished lung sounds in the right lobes and occasional coarse crackles are concerning for a respiratory infection or condition such as pneumonia or bronchiolitis. Immediate follow-up is required to assess the cause and severity of the respiratory findings.
I. Temperature: The infant has a fever, which is concerning, especially with poor feeding and lethargy. Fever in an infant can indicate a serious infection (e.g., sepsis, urinary tract infection, or pneumonia) that requires immediate medical attention and further investigation.
J. Oxygen saturation: An oxygen saturation of 92% is low for an infant, indicating hypoxia, likely due to respiratory compromise. Immediate intervention (e.g., oxygen therapy) is necessary to prevent further deterioration.

A. Apply a transparent dressing to the site after the venipuncture. A pressure dressing is more appropriate to control bleeding in a child with hemophilia.
B. Apply a cold compress to the site prior to obtaining the sample. Cold compresses reduce swelling but are not required prior to venipuncture.
C. Perform an Allen test prior to obtaining the blood sample. An Allen test is used to evaluate arterial circulation before arterial blood sampling, not for venipuncture.
D. Obtain the sample using venipuncture. Venipuncture is preferred over heel sticks or finger pricks for children with hemophilia because it minimizes trauma and bleeding.
