A nurse at a clinic is counseling a client who has a positive pregnancy test. The first day of the client's last menstrual period was November 9. Use Nägele's rule to calculate the estimated date of delivery.
(Use the MMDD format with four numerals and no spaces or punctuation.)
The Correct Answer is ["0816"]
To calculate the estimated date of delivery using Nägele's rule, follow these steps:
-Add 7 days to the first day of the last menstrual period. In this case, November 9 + 7 days = November 16.
- Subtract 3 months from the month of the last menstrual period. In this case, November - 3 months = August.
The estimated date of delivery is August 16
The rationale for this rule assumes that the average menstrual cycle is 28 days long and that ovulation occurs on day 14 of the cycle. Therefore, adding 7 days to the first day of the last menstrual period approximates the date of conception. Subtracting 3 months from the month of the last menstrual period adjusts for the difference between the lunar calendar (13 months) and the Gregorian calendar (12 months).

Choice A rationale:
Padded wrist restraints are not appropriate unless there's a clear clinical indication to prevent self-harm or injury.

Choice D rationale:
Placing an incontinence brief is not necessary unless there's a specific indication, and it doesn't directly relate to post-seizure care.
