clinical definitions necessary for deciphering complex question stems. Understanding these
terms prevents misinterpretation of distractors.

Essential Formula Sheet & Calculation Protocols
A. Naegele’s Rule (Estimated Date of Delivery)
Used to calculate the Estimated Date of Confinement (EDC) or Delivery (EDD) based on the
First Day of the Last Menstrual Period (LMP).
Step Action Example (LMP: Sept 10)
1 Identify First Day of LMP September 10
2 Subtract 3 Months June (9 - 3 = 6)
3 Add 7 Days 17 (10 + 7 = 17)
4 Add 1 Year (if needed) Next Year
Result EDD June 17
**
B. GTPAL System (Obstetric History)
A detailed method for recording pregnancy history that provides a comprehensive risk profile.
Letter Represents Key Calculation Rule
G Gravida Total number of pregnancies
(including current).
T Term Births at 37+ weeks gestation.
P Preterm Births between 20 and 36.6
weeks gestation.
A Abortions Pregnancies ending before 20
weeks (spontaneous or
induced).
L Living Current number of living
children.
Expert Note: Multiple births (twins/triplets) count as 1 for G, T, or P, but as 2 (or more) for L.
C. Magnesium Sulfate Calculations
Critical for Preeclampsia and Preterm Labor management. The therapeutic window is narrow,
requiring precise dosage.
● Loading Dose: 4–6 g IV over 15–30 minutes.
● Maintenance Dose: 1–3 g/hour via infusion pump.
● Therapeutic Serum Range: 4–7 mg/dL.
● Toxicity Threshold: > 8 mg/dL (Loss of DTRs often occurs first).
D. APGAR Scoring (Newborn Assessment)
Performed at 1 and 5 minutes of life to assess transition to extrauterine life.
