A woman arrives at the clinic for a pregnancy test.
Her last menstrual period (LMP) was February 14, 2019.
What is the client’s expected date of birth (EDB)?
September 17, 2019.
November 21, 2019.
December 17, 2019.
November 7, 2019.
The Correct Answer is C
Choice A rationale
Calculating from the LMP of February 14, 2019, the estimated date of birth using Naegele's rule would not fall in September.
Choice B rationale
Naegele's rule calculates EDB by adding 7 days to the LMP and then subtracting 3 months. This does not lead to a November date.
Choice C rationale
Using Naegele's rule, adding 7 days to February 14 results in February 21, 2019, then subtracting 3 months, results in November 2019.
Choice D rationale
While close, November 7 is not accurate. Naegele's rule would adjust from February 14, giving an EDB in mid to late November.

Correct Answer is ["A","B"]
Explanation
Choice A rationale
Calling for help and notifying the care provider ensures that expert medical assistance is available promptly for any emergency interventions required.
Choice B rationale
Getting help and preparing the operating room ensures readiness for an immediate cesarean section if fetal distress persists and the situation does not improve rapidly.
Choice C rationale
Starting Pitocin is inappropriate during fetal distress as it may further stress the fetus by increasing contraction frequency and intensity, potentially worsening the situation.
Choice D rationale
Inserting a Foley catheter does not address the immediate concern of fetal distress and would not provide immediate benefit in improving fetal heart rate.
Choice E rationale
Repeating uterine resuscitation measures (e.g., repositioning, oxygen, IV fluids) is essential, but if they are ineffective, additional interventions, such as preparing for possible surgical delivery, are needed.
