A client arrives to the prenatal clinic for their first prenatal assessment. They tell the nurse that the first day of their last menstrual period (LMP) was April 19, 2024.
Using Naegele's rule, the nurse informs the client that their estimated date of delivery is which date? Please record answer as MM/DD/YYYY.
01/25/2025
01/26/2025
01/27/2025
01/24/2025
The Correct Answer is B
Step 1 is: Add 7 days to the first day of the last menstrual period (LMP). April 19 + 7 days = April 26.
Step 2 is: Subtract 3 months from the month of the LMP. April (4th month) - 3 months = January (1st month).
Step 3 is: Add 1 year to the year of the LMP. 2024 + 1 year = 2025.
Step 4 is: Combine the new month, day, and year to determine the estimated date of delivery (EDD). The final calculated answer is 01/26/2025.

Correct Answer is D
Explanation
Choice A rationale
Assessing the characteristics of the amniotic fluid (color, odor, amount, consistency) is an important step after amniotomy, as meconium-stained fluid indicates fetal stress. However, checking the fetal heart rate (FHR) is the priority because a sudden change or drop in FHR may indicate a prolapsed umbilical cord, a life-threatening emergency, making immediate FHR assessment the most critical intervention.
Choice B rationale
Monitoring for infection is a necessary long-term post-amniotomy intervention because the rupture of the amniotic membranes breaks the protective barrier to the uterus. The nurse should check the client's temperature every 2 hours after the procedure. However, the immediate risk is fetal compromise from a cord prolapse, which must be ruled out first.
Choice C rationale
Inspecting the perineum for bloody discharge is part of the overall assessment, as labor progression and cervical changes can cause some bloody show. However, new heavy bright red bleeding could indicate a placental abruption, which is a concern. The most critical and immediate danger following amniotomy is umbilical cord prolapse, making FHR assessment the priority.
Choice D rationale
The priority intervention immediately after an amniotomy is to check the fetal heart rate (FHR) for a full minute. This is done to detect a potential umbilical cord prolapse, which can occur if the gush of amniotic fluid sweeps the cord out ahead of the presenting part, causing fetal bradycardia or variable decelerations due to cord compression and cutting off the fetus's oxygen supply.
Correct Answer is ["8"]
Explanation
Step 1 is: Calculate the total amount of oxytocin in milliunits (mU):. 30 units × (1,000 mU/1 unit) = 30,000 mU.
Step 2 is: Calculate the concentration of oxytocin in mU/mL:. 30,000 mU ÷ 500 mL = 60 mU/mL.
Step 3 is: Calculate the total amount of oxytocin administered per hour (mU/hr):. 60 mU/mL × 8 mL/hr = 480 mU/hr.
Step 4 is: Convert the infusion rate from mU/hr to mU/min:. 480 mU/hr ÷ 60 min/hr = 8 mU/min. Final calculated answer: 8mU/min
