To calculate the gestational age and estimated due date (EDD) for Abebech based on the information provided, follow these steps:
- Last Normal Menstrual Period (LNMP): 23/2/2017 E.C.
- Today's date (ANC visit date): 2/9/2017 E.C.
Calculating Gestational Age:
- Start from the LNMP: 23/2/2017 E.C.
- Count the number of weeks from the LNMP to the ANC visit date.
February 23, 2017, to March 23, 2017: 4 weeks
March 23, 2017, to April 23, 2017: 4 weeks
April 23, 2017, to May 23, 2017: 4 weeks
May 23, 2017, to June 23, 2017: 4 weeks
June 23, 2017, to July 23, 2017: 4 weeks
July 23, 2017, to August 23, 2017: 4 weeks
August 23, 2017, to September 2, 2017: Approximately 1.5 weeks
Adding these together:
- 4 + 4 + 4 + 4 + 4 + 4 + 1.5 = 25.5 weeks
Therefore, Abebech is approximately 26 weeks pregnant at her ANC visit on 2/9/2017.
Calculating Estimated Due Date (EDD):
To calculate the estimated due date, we typically add 280 days (or 40 weeks) to the LNMP.
- LNMP: 23/2/2017 E.C.
- Add 40 weeks:
Calculating from LNMP:
- 40 weeks = 280 days
- 23/2/2017 + 280 days ≈ 29/11/2017
Thus, the Estimated Due Date (EDD) for Abebech will be approximately 29/11/2017 E.C.
Summary:
- Gestational Age: Approximately 26 weeks
- Estimated Due Date (EDD): 29/11/2017 E.C.
