A nurse in a prenatal clinic is determining a client’s estimated date of delivery using Naegels rule. The first day of her last menstrual period was May 4. Which of the following dates should the nurse tell the client is her estimated date of delivery?
February 11
April 27
February 27
April 11
The Correct Answer is A
A. February 11:
The first day of the client’s last menstrual period is May 4.
- Subtract 3 months: May → April → March → February.
- Add 7 days: 4 + 7 = 11.
- The EDD is February 11.
B. April 27: This date is beyond 40 weeks of pregnancy. Using Naegele's rule correctly should result in a February due date, not an April date.
C. February 27: While February is the correct month, this date does not align with Naegele’s Rule because the addition of 7 days to May 4 results in February 11, not February 27.
D. April 11: April 11 places the due date in the wrong month. This choice may result from adding 7 days without adjusting the months correctly when subtracting 3 months.

Correct Answer is D
Explanation
A. The client will be asked to stimulate her nipples for 5 min during the test. Nipple stimulation is used during a contraction stress test, not a nonstress test. The nonstress test only monitors the fetal heart rate without inducing contractions.
B. The client will receive an ultrasound prior to the test. An ultrasound is not a routine part of a nonstress test. The nonstress test only involves monitoring the fetal heart rate using an external monitor.
C. An IV will be initiated prior to the test. An IV is not necessary for a nonstress test as it is a noninvasive procedure that only requires external monitoring of the fetal heart rate.
D. An external fetal monitor will be used to monitor the FHR. A nonstress test involves the use of an external fetal monitor to assess the fetal heart rate and its response to fetal movements. This helps determine fetal well-being.
Correct Answer is C
Explanation
A. February 27: This date does not match Naegele's rule calculation.
B. April 11: This is too late for the estimated due date using Naegele's rule.
C. February 11: Using Naegele’s rule, subtracting 3 months from May 4 gives February 4, and then adding 7 days results in February 11.
D. April 27: This date is too late for the estimated due date based on Naegele's rule.
