This question is incomplete because the options are missing; here is the complete question:
A primiparous mother gave birth to an 8 lb 12 oz (4 kg) infant daughter yesterday. She is being bottle-fed, is Rh-positive, has a cephalohematoma, and received her hepatitis A vaccine last evening. Which factor places the newborn at risk for the development of jaundice:
A. Formula feeding
B. Cephalohematoma
C. Female gender
D. Hepatitis A vaccine
E. Rh-positive blood type
The answer to this question is B. Cephalohematoma
Explanation:
Jaundice is a condition caused by high levels of bilirubin, yellow pigment. This causes the skin and membranes to look yellow. Additionally, bilirubin is produced if red blood cells break down, which occurs if there are large hematomas. This implies, in the case presented the risk factor for jaundice is the cephalohematoma in the infant because this causes red cell to break down, which increases bilirubin and causes jaundice. Also, other factors such as the hepatitis vaccine, formula feeding, or the female gender do not contribute to this condition.
