A nurse is caring for a client who had a vaginal delivery 1 day ago. The nurse determines that the client's fundus is firm, located 2 fingerbreadths above the umbilicus, and deviated to the left. Which of the following actions should the nurse take first?

A) Incorrect- Checking urine for ketones is not necessary if the newborn's blood glucose level is low but stable and the baby is asymptomatic.
B) Incorrect- Administering glucagon is not indicated for an asymptomatic newborn with a low but stable blood glucose level.
C) Correct - Encouraging additional feeding is appropriate for an asymptomatic newborn with a low blood glucose level. Regular feeding can help increase blood glucose levels.
D) Incorrect- Waiting 4 hours to recheck blood glucose might not be appropriate if the baby's blood glucose is currently low. Addressing the low blood glucose level is more immediate.

A. Elevated blood pressure is typically associated with gestational hypertension or preeclampsia rather than hyperemesis gravidarum. In hyperemesis, the significant fluid loss through protracted vomiting more commonly leads to hypovolemia and a subsequent decrease in systemic blood pressure. While compensatory tachycardia may occur, hypertension is not a direct scientific expectation for this clinical condition.

B. Leukopenia, which is a decrease in the white blood cell count, is not a typical finding in clients suffering from hyperemesis gravidarum. Hemoconcentration caused by severe dehydration may actually result in a relative increase in various laboratory values, including hematocrit and occasionally white cell counts. There is no physiological mechanism within this disorder that causes the bone marrow suppression required for leukopenia.

C. Hydramnios, or excessive amniotic fluid volume, is generally associated with fetal anomalies or maternal diabetes rather than severe vomiting. Hyperemesis gravidarum is characterized by a state of maternal fluid volume deficit rather than an excess of amniotic fluid. In severe, untreated cases, maternal dehydration might actually lead to decreased placental perfusion and a potential reduction in amniotic fluid.

D. Ketonuria is a critical finding in hyperemesis gravidarum that indicates the body has shifted to an anaerobic metabolic state. Because the client cannot retain sufficient carbohydrates for energy, the body begins catabolizing adipose tissue to produce fuel, resulting in the accumulation of ketone bodies. The presence of these ketones in the urine confirms that the client is experiencing metabolic starvation and requires immediate intervention.
