A primigravida dilated to 5 cm has just received an epidural for pain.She complains of feeling lightheaded and dizzy within 10 minutes after the procedure.
Her blood pressure before the procedure was 120/80 and is now 80/52. Which of the following medications is used in this situation?
Ergonovine maleate.
Epoetin.
Adrenaline.
Ephedrine.
The Correct Answer is D
Choice A rationale
Ergonovine maleate is used to treat postpartum hemorrhage by causing uterine contractions. It is not used to treat hypotension caused by epidural anesthesia.
Choice B rationale
Epoetin is a medication used to treat anemia by stimulating the production of red blood cells. It is not used to treat hypotension caused by epidural anesthesia.
Choice C rationale
Adrenaline (epinephrine) is used in emergency situations to treat severe allergic reactions, cardiac arrest, and severe asthma attacks. It is not the first-line treatment for hypotension caused by epidural anesthesia.
Choice D rationale
Ephedrine is a medication used to treat hypotension caused by epidural anesthesia. It increases blood pressure by stimulating the release of norepinephrine and improving cardiac output.

Correct Answer is A
Explanation
Choice A rationale
Proteinuria and vomiting at 35 weeks gestation are significant symptoms that could indicate preeclampsia, a serious condition that requires immediate assessment and management to prevent complications for both the mother and the baby.
Choice B rationale
Urinary urgency, frequency, and burning at 39 weeks gestation suggest a possible urinary tract infection (UTI), which is concerning but generally not as immediately critical as symptoms suggesting preeclampsia.
Choice C rationale
A fasting blood sugar of 95 mg/dL and a 3-hour glucose of 120 at 30 weeks gestation indicate good control of blood sugar levels, which is not as high-risk as preeclampsia symptoms.
Choice D rationale
A hemoglobin of 12 mg/dL and a potassium level of 3.5 mEq/L at 34 weeks gestation are within normal ranges and do not indicate an immediate high-risk condition compared to the potential for preeclampsia.
Correct Answer is ["0.76"]
Explanation
Step 1 is 3800 grams × 0.1 mg/kg. 3800 grams × 0.1 mg/kg = 380 mg.
Step 2 is 380 mg ÷ 0.5 mg/mL. 380 mg ÷ 0.5 mg/mL = 760 mL. Final calculated answer: 0.76 mL. .
