What is the estimated date of birth (EDB) for a client who is pregnant and whose last menstrual period began on July 27? (State the date in MMDD.
For example, July 27 is 0727)

A.

0427

B.

0503

C.

0603

D.

0527

Answer and Explanation

The Correct Answer is B

To calculate the estimated date of birth (EDB) using the first day of the last menstrual period (LMP), you can use Naegele’s Rule. This rule adds 280 days (or 40 weeks) to the first day of the LMP.

Given the LMP of July 27 (0727):

  1. Add 1 year: July 27, 2023 becomes July 27, 2024.
  2. Add 7 days: July 27, 2024 becomes August 3, 2024.
  3. Subtract 3 months: August 3, 2024 becomes May 3, 2024.

So, the estimated date of birth (EDB) is May 3, 2024 (0503).

Correct Answer is A

Explanation

Choice A rationale
The client’s symptoms and lab results are consistent with HELLP Syndrome, a severe form of preeclampsia. HELLP stands for Hemolysis, Elevated Liver enzymes, and Low Platelet count. The client’s elevated liver enzymes and low platelets, along with the reported symptoms, are indicative of this condition.
Choice B rationale
While the client’s high blood pressure could suggest Postpartum hypertension, the presence of severe headaches, visual disturbances, right upper quadrant pain, and abnormal lab results point more towards HELLP Syndrome.
Choice C rationale
Hypertension in pregnancy could be a possibility, but it does not explain all of the client’s symptoms and lab results, particularly the elevated liver enzymes and low platelets.
Choice D rationale

Superimposed preeclampsia is a condition where a pregnant woman with chronic hypertension develops preeclampsia. However, the client’s severe symptoms and lab results are more indicative of HELLP Syndrome.

Correct Answer is A

Explanation

Choice A rationale
Placing the client in a lateral position can help improve blood flow to the uterus and placenta, which can help stabilize the client’s blood pressure and the fetal heart rate.
Choice B rationale
Monitoring vital signs every 5 minutes is important, but the priority action is to address the client’s low blood pressure, which can compromise blood flow to the fetus.
Choice C rationale
Elevating the client’s legs can help increase venous return and improve blood pressure, but it is not the priority action in this situation.
Choice D rationale
Notifying the provider is important, but the nurse should first take action to stabilize the client’s condition.
