A nurse is caring for a 26-year-old female client who is at 14 weeks of gestation in the antepartum clinic. Exhibits The nurse should anticipate a provider prescription for dropdown due to the client’s dropdown.

The nurse should anticipate a provider prescription for pyridoxine due to the client’s severe dehydration. Rationale for correct answers Pyridoxine (vitamin B6) is recommended for nausea and vomiting in pregnancy (NVP), commonly known as hyperemesis gravidarum (HG), especially in patients with persistent symptoms leading to dehydration. Severe dehydration is confirmed by elevated urine specific gravity (normal: 1.002–1.030), low sodium (normal: 135–145 mEq/L), and positive ketones, indicating excessive vomiting and malnutrition. Rationale for incorrect Response 1 options Antibiotics: There is no evidence of infection; urinalysis and WBC count are within normal limits. Magnesium sulfate: Used for eclampsia or preterm labor prevention, not for HG. Oxytocin: Stimulates uterine contractions and is contraindicated during early pregnancy unless labor induction is required. Rationale for incorrect Response 2 options Urinary tract infection: No leukocytes or nitrites in urine, and WBC count is normal (4,500–11,000/mm³). Preeclampsia: No proteinuria or hypertension (≥140/90 mm Hg). Preterm labor: No uterine contractions or cervical changes.
