Question 3 of 5
The nurse is counseling a woman who wants to become pregnant. The woman tells the nurse that she has a 28-day menstrual cycle and the first day of her menstrual period was January 8. The nurse correctly calculates that the woman's next fertile period is?
Correct Answer: D
Rationale: Ovulation typically occurs around day 14 of a 28-day cycle, counting from the first day of the menstrual period. The fertile period includes about 5 days before and 1 day after ovulation due to sperm survival time. For a cycle starting January 8, day 14 is January 21, so the fertile window is approximately January 16-22. January 14-15 falls within this window, accounting for early ovulation variability.
