A nurse is caring for a 28-year-old female client who is at 12 weeks of gestation and has been admitted to the emergency department with excessive vomiting for the past 48 hours. The client has lost 2.3 kg (5 lb) over 2 days.

Exhibits

The nurse is assessing the client 24 hours later. How should the nurse interpret the findings 24 hours later? For each finding, click to specify whether the finding is unrelated to the diagnosis, a sign of potential improvement, or a sign of potential worsening.

Choice A rationale: A positive Coombs test indicates that the newborn has antibodies against his own red blood cells, which can lead to hemolytic disease of the newborn. This condition can cause severe anemia and jaundice, which can lead to complications such as kernicterus if not treated promptly.

Choice B rationale: The newborn’s glucose level is within the normal range (40 to 60 mg/dL), so this finding does not require immediate follow-up.

Choice C rationale: The yellow color of the sclera indicates jaundice, which can be a sign of hyperbilirubinemia. This condition can lead to complications such as kernicterus if bilirubin levels become too high.

Choice D rationale: The absence of meconium stool in a 36-hour-old newborn is unusual, as most newborns pass meconium within the first 24 to 48 hours after birth. This could indicate a problem such as meconium ileus or Hirschsprung disease, which would require further evaluation.

Choice E rationale: The head assessment finding of caput succedaneum is a common and typically harmless condition in newborns caused by pressure on the head during delivery. It does not require immediate follow-up.

Choice F rationale: The newborn’s heart rate is slightly elevated (normal range for a newborn is 120-160 beats per minute). This could be a response to factors such as fever, pain, or distress, and should be reported to the provider.

Choice G rationale: The newborn’s respiratory rate is also elevated (normal range for a newborn is 30-60 breaths per minute). This could be a sign of respiratory distress and should be reported to the provider.

Choice H rationale: Dry mucous membranes can be a sign of dehydration, which can occur if the newborn is not feeding well or is losing too much fluid, for example, through excessive sweating due to fever. This should be reported to the provider.

Choice A rationale
Irregular contractions of 10 to 20 seconds in duration that are not felt by the client during a nonstress test may indicate a need for further diagnostic testing. These could be Braxton Hicks contractions, which are normal, but if they become regular and increase in intensity, they could indicate preterm labor.
Choice B rationale
An increase in fetal heart rate to 150/min above the baseline of 140/min lasting 10 seconds in response to fetal movement within a 40-min testing period is a normal finding on a nonstress test. This is known as a reactive nonstress test and indicates that the fetus is well-oxygenated.
Choice C rationale
No late decelerations in the fetal heart rate noted with three uterine contractions of 60 seconds in duration within a 10-min testing period is a normal finding on a nonstress test. Late decelerations can indicate fetal hypoxia.
Choice D rationale
Three fetal movements perceived by the client in a 20-min testing period is a normal finding on a nonstress test. Fetal movement is a positive sign of fetal well-being.
