What is the recommended antibiotic therapy for the treatment of pyelonephritis in pregnancy?
Ciprofloxacin
Ceftriaxone
Amoxicillin
Trimethoprim-sulfamethoxazole (TMP-SMX)
The Correct Answer is B
A. Ciprofloxacin: Ciprofloxacin is a fluoroquinolone, which is contraindicated in pregnancy due to potential adverse effects on fetal cartilage development.
B. Ceftriaxone: Ceftriaxone, a third-generation cephalosporin, is commonly used in pregnancy for pyelonephritis because it is safe and effective against common uropathogens.
C. Amoxicillin: Amoxicillin is not typically the first-line treatment for pyelonephritis because of increasing resistance and less effectiveness against severe infections.
D. Trimethoprim-sulfamethoxazole (TMP-SMX): TMP-SMX is generally avoided in pregnancy, especially in the first trimester (due to neural tube defect risk) and near term (due to kernicterus risk in the newborn).

Correct Answer is A
Explanation
A. Variable decelerations are due to umbilical cord compression. Variable decelerations are characterized by abrupt decreases in FHR, often with a "V" or "U" shape. They are caused by umbilical cord compression, which disrupts fetal oxygenation.
B. Variable decelerations are a result of the administration of IV narcotic analgesics. Narcotic analgesics (e.g., morphine, fentanyl) cause decreased FHR variability and prolonged decelerations, not variable decelerations.
C. Variable decelerations are caused by uteroplacental insufficiency. Uteroplacental insufficiency causes late decelerations, not variable decelerations.
D. Variable decelerations are related to fetal head compression. Fetal head compression causes early decelerations, which are gradual and mirror contractions, unlike variable decelerations.
Correct Answer is A
Explanation
A. Intravenous (IV) therapy to correct fluid and electrolyte imbalances: The primary concern in hyperemesis gravidarum is dehydration and electrolyte imbalances due to excessive vomiting. IV fluids are the first-line treatment to restore hydration and correct any imbalances.
B. Enteral nutrition to correct nutritional deficits: Enteral nutrition is considered if the client cannot tolerate oral intake after initial IV therapy, but it is not the first-line treatment.
C. Corticosteroids to reduce inflammation: Corticosteroids are not typically used for hyperemesis gravidarum. They may be considered in severe, refractory cases, but they are not part of the initial treatment.
D. Antiemetic medication, such as pyridoxine, to control nausea and vomiting: Although pyridoxine (vitamin B6) and antiemetics are commonly used to manage nausea, the initial priority is rehydration and correction of electrolyte imbalances before initiating oral medications.
