A nurse reviews a pregnant client's labs and notes that the client has a HbA1c of 7.5%. What is the priority concern?

Hyperemesis gravidarum is a pathological state of intractable vomiting resulting in ketonuria, dehydration, and significant electrolyte depletion. The clinical management aims to restore hemodynamic stability and suppress the overactive emetic reflex. Interventions focus on maintaining metabolic homeostasis and preventing Wernicke’s encephalopathy through thiamine and fluid replacement.

A. Antiemetics: Pharmacological management using pyridoxine, doxylamine, or ondansetron is necessary to interrupt the vomiting cycle. These medications act on the chemoreceptor trigger zone or vestibular system to reduce nausea. Effective suppression of emesis allows for the gradual reintroduction of oral nutrition and hydration.

B. Fluid restriction: Restricting fluids is contraindicated and dangerous for a client already suffering from intravascular dehydration. Adequate hydration is the cornerstone of therapy to prevent renal failure and maintain uteroplacental perfusion. Restricting intake would exacerbate tachycardia and orthostatic hypotension.

C. Avoid triggers: Identifying and eliminating environmental stimuli like strong odors, flickering lights, or specific textures reduces sensory input to the emetic center. Behavioral modification is a non-pharmacological necessity to prevent recurrent episodes of nausea. This helps stabilize the gastric mucosa and CNS.

D. IV fluids: Intravenous rehydration with isotonic crystalloids is the priority intervention for clients unable to tolerate oral intake. This corrects volume deficits and replenishes depleted electrolytes like potassium and chloride. It is essential for reversing metabolic alkalosis caused by loss of gastric acid.

E. Small frequent meals: Once vomiting is controlled, consuming low-fat, high-carbohydrate snacks every 2 to 3 hours prevents an empty stomach. Maintaining stable blood glucose levels minimizes gastric contractions and acid irritation. This dietary strategy supports weight gain and fetal development.

Ambulation during the first stage of labor utilizes gravity to assist in the descent of the fetal presenting part into the pelvis. Vertical positioning increases the efficiency of uterine contractions and encourages pelvic expansion. It is a key component of active labor management to improve outcomes.

A. Prevents contractions: Walking actually tends to strengthen and regularize uterine contractions rather than preventing them. The pressure of the fetal head against the cervix during ambulation stimulates the release of endogenous oxytocin. It promotes physiologic labor progression.

B. Reduces Dilation: Movement and upright positions are associated with faster cervical dilation compared to the lithotomy or supine positions. Gravity helps the fetus exert consistent pressure on the internal os. This mechanical stimulation accelerates the effacement process.

C. Slows labor: Evidence suggests that being mobile can actually shorten the duration of the first stage of labor. Remaining sedentary can lead to stalled labor and increased maternal discomfort. Ambulation promotes optimal fetal positioning (occiput anterior), which facilitates a smoother delivery.

D. Promotes fetal descent: Walking helps the fetus navigate the pelvic inlet and descend through the mid-pelvis. The swaying motion of the maternal hips helps the fetus rotate and engage properly. This reduces the risk of dystocia and the need for operative interventions.
