A nurse in a prenatal clinic is caring for a client who is pregnant and asks the nurse for her estimated date of birth (EDB). The client's last menstrual period began on July 27. What is the client's EDB? (State the date in MMDD format. For example, July 27 is 0727.)

Answer and Explanation

The Correct Answer is ["0504"]

To calculate the estimated date of birth (EDB), also known as the due date, we use Naegele's Rule, which involves adding one year, subtracting three months, and adding seven days to the first day of the last menstrual period (LMP). Using this rule, if the LMP was on July 27, the EDB would be:

- Add one year: July 27, 2024
- Subtract three months: April 27, 2024
- Add seven days: May 4, 2024

Therefore, the EDB in MMDD format is 0504.
Reason:
Naegele's Rule is a standard way of calculating the due date for a pregnancy. The rule estimates the expected date of delivery (EDD) by adding one year, subtracting three months, and adding seven days to the date of a woman's last menstrual period (LMP). This calculation assumes a regular menstrual cycle of 28 days and ovulation occurring on the 14th day of the cycle. The EDB is typically set at 40 weeks from the LMP, which is approximately 280 days. While this method provides an estimate, only about 4% of births occur on the exact due date, and most births occur within a range of two weeks before or after the estimated due date.

It's important to note that the EDB is an estimate and can be influenced by factors such as the length of menstrual cycles, the exact day of ovulation, and the date of conception. Ultrasounds and other prenatal tests can provide additional information to refine the due date estimate as the pregnancy progresses.

Correct Answer is C

Explanation

Choice a reason:
The viability of the fetus at 38 weeks of gestation is typically not the primary concern when heavy, red vaginal bleeding occurs without contractions. Fetal movements reported by the mother are a good sign of fetal well-being. However, the ultrasound in this scenario is more likely to be used to rule out placental issues that could cause bleeding, rather than to assess fetal viability.

Choice b reason:
The biparietal diameter (BPD) is a measurement taken during an ultrasound to assess fetal growth and development. While BPD is an important parameter, it is not typically the focus of an urgent ultrasound in the context of heavy vaginal bleeding late in pregnancy. The BPD is more relevant to growth assessments rather than acute bleeding episodes.

Choice c reason:
Locating the placenta is crucial in the case of heavy, red vaginal bleeding at 38 weeks of gestation. The bleeding could be indicative of placental abruption or placenta previa, both of which are serious conditions that require immediate medical attention. An ultrasound can quickly determine the location of the placenta and assess for these conditions.

Choice d reason:
Assessing fetal lung maturity is not typically the priority in an emergency situation involving heavy vaginal bleeding. While lung maturity is an important consideration for the timing of delivery, especially in preterm labor, the immediate concern in this scenario would be to identify the source of bleeding and ensure the safety of both the mother and fetus.

A. Postpartum hemorrhage B. Postpartum infection C. Thromboembolic events D. Hypertension

Correct Answer is A

Explanation

Choice a reason:
Methylergonovine is a medication used to prevent postpartum hemorrhage, which is excessive bleeding following childbirth. It works by causing the uterine muscles to contract, thereby reducing blood loss. Postpartum hemorrhage is a significant cause of maternal morbidity and mortality worldwide, and methylergonovine is one of the medications used as a prophylactic measure to manage this risk.

Choice b reason:
While postpartum infections are a concern after childbirth, methylergonovine is not used to prevent infections. Postpartum infections can occur in different parts of the body, such as the uterus (endometritis), the urinary tract, or the site of an episiotomy or cesarean section incision. Prevention of postpartum infections typically involves hygiene practices, antibiotic prophylaxis when indicated, and monitoring for signs of infection.

Choice c reason:
Thromboembolic events, which include deep vein thrombosis and pulmonary embolism, are also a risk during the postpartum period. However, methylergonovine is not used to prevent these conditions. Prevention of thromboembolic events in the postpartum period may involve the use of anticoagulants, mechanical methods such as compression stockings, and early mobilization.

Choice d reason:
Hypertension, or high blood pressure, may be observed during the postpartum period, but methylergonovine is not indicated for the prevention of hypertension. Management of postpartum hypertension typically includes antihypertensive medications and monitoring of blood pressure levels. Methylergonovine can actually cause an increase in blood pressure as a side effect, so it must be used cautiously in individuals with hypertension.
