A couple is planning the conception of their first child.
The wife, whose normal menstrual cycle is 34 days in length, correctly identifies the time that she is most likely to ovulate if she states that ovulation should occur on day:
A . 14+2 days
B . 16+2 days
C . 20+2 days
D . 22+2 days
Answer: C
Explanation:
(A) Ovulation is dependent on average length of menstrual cycle, not standard 14 days.
(B) Ovulation occurs 14+2 days before next menses (34 minus 14 does not equal 16).
(C) Ovulation occurs 14+2 days before next menses (34 minus 14 equals 20).
(D) Ovulation occurs 14+2 days before next menses (34 minus 14 does not equal 22).
