A nurse is performing an admission assessment on a client who had a recent positive pregnancy test. The first day of her last menstrual period (LMP) was May 8. According to Nägele's rule, which of the following dates should the nurse document as the client's estimated date of birth (EDB)?
February 1
February 8
February 15
February 22
The Correct Answer is C
A. February 1 is not the correct EDB according to Nägele's rule. Nägele's rule states that to estimate the EDB, subtract three months from the LMP and add seven days and one year. Therefore, May 8 minus three months is February 8, plus seven days is February 15, plus one year is February 15 of the following year.
B. February 8 is not the correct EDB according to Nägele's rule. Nägele's rule states that to estimate the EDB, subtract three months from the LMP and add seven days and one year. Therefore, May 8 minus three months is February 8, plus seven days is February 15, minus seven days is February 8, plus one year is February 8 of the following year.
C. February 15 is the correct EDB according to Nägele's rule. Nägele's rule states that to estimate the EDB, subtract three months from the LMP and add seven days and one year. Therefore, May 8 minus three months is February 8, plus seven days is February 15, plus one year is February 15 of the following year.
D. February 22 is not the correct EDB according to Nägele's rule. Nägele's rule states that to estimate the EDB, subtract three months from the LMP and add seven days and one year. Therefore, May 8 minus three months is February 8, plus seven days is February 15, plus seven days is February 22, plus one year is February 22 of the following year.

Correct Answer is B
Explanation
A is incorrect because massaging bony prominences on the client's left side can increase the risk of skin breakdown and pressure ulcers. The nurse should avoid applying pressure to areas with impaired circulation or sensation.
B is correct because supporting the client's left arm on a pillow while sitting can prevent edema, contractures, and nerve damage. The nurse should also encourage the client to perform active and passive range of motion exercises on their left arm.
C is incorrect because positioning the bedside table on the client's left side can discourage the client from using their right side, which can lead to neglect and learned nonuse. The nurse should position the bedside table on the client's right side and encourage them to reach for items with their right hand.
D is incorrect because placing the client's cane on their left side while ambulating can cause instability and falls. The nurse should place the cane on the client's right side and instruct them to move their left leg and cane together, followed by their right leg.
