0800:
A 28-year-old nulliparous female comes to the clinic for confirmation of suspected pregnancy due to amenorrhea and a positive home pregnancy test. The client's current exercise regimen includes indoor cycling and outdoor running. The client reports nausea, vomiting, and breast tenderness. She has a 28-day menstrual cycle, and her last menstrual period was March 10- 17. The health care provider notes a bluish-purple vaginal mucosa and cervix during pelvic examination and confirms a 12-week intrauterine pregnancy by sonography. A fetal heart rate of 155/min is detected with handheld Doppler.
The client's last menstrual period was March 10-17. Unprotected intercourse occurred on March 24. The client's menstrual cycles are regular and occur every 28 days. Based on the Naegele rule, what is the estimated date of birth?
Correct Answer: B
Rationale: Using Naegele's rule (first day of LMP + 1 year - 3 months + 7 days), March 10, 2025 + 1 year = March 10, 2026 - 3 months = December 10, 2025 + 7 days = December 17, 2025.
