A nurse is reinforcing teaching about perineal care to a client who is 2 hr postpartum and has an episiotomy and hemorrhoids. Which of the following statements by the client indicates an understanding of the teaching?

A) Incorrect- Having a high-fat snack before bed might exacerbate nausea. It's generally recommended to have a light snack if needed.
B) Incorrect- Eating small, frequent snacks between meals can help manage nausea by preventing an empty stomach.
C) Incorrect- Drinking water with meals might not necessarily help with nausea and might worsen the feeling of fullness.
D) Correct - "Eat a slice of dry toast before getting out of bed" can help alleviate morning sickness in the first trimester. Eating a small, bland snack before rising can prevent an empty stomach, which can contribute to nausea.

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.
