LNMP stands for which term?

• A. Last Menstrual Period
• B. Last Normal Menstrual Period
• C. Last Noted Menstrual Period
• D. Last Normal Menstrual Period

Answer: (D)

LNMP stands for the date of the first day of the last normal menstrual period. This term is used as the reference point for dating pregnancy and estimating gestational age, because a regular, normal cycle provides a consistent baseline for counting days from ovulation to the due date. The qualifier “normal” matters since irregular cycles can make dating unreliable, so the phrase emphasizes a standard, regular cycle. The other options either omit the qualifier or use nonstandard phrasing, which is not the accepted term.
