A nurse is calculating the estimated date of birth using Nägele's rule for a client who is pregnant and whose last menstrual cycle started June 21. Which of the following is the estimated date of delivery in the next year?
March 28.
March 21.
April 4.
March 14.
The Correct Answer is A
Nägele’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 first day of a woman’s last menstrual period (LMP).
So, if the last menstrual cycle started on June 21, here’s how you calculate:
- Subtract 3 months from June 21, which gives you March 21.
- Add 7 days to March 21, which gives you March 28.
- Add 1 year to the current year.
So, the estimated date of delivery in the next year would be March 28.

Correct Answer is D
Explanation
Choice A rationale:
Uterine hypertonicity is associated with labor complications, not placenta previa.
Choice B rationale:
A persistent headache is not a typical symptom of placenta previa.
Choice C rationale:
A firm, rigid abdomen is a sign of a possible uterine rupture, not placenta previa.
Choice D rationale:
Painless, vaginal bleeding is a classic symptom of placenta previa, so this statement is correct.
Correct Answer is A
Explanation
Choice A rationale:
Yellow exudate will form at the surgical site in 24 hours, which is a normal part of the healing process.
Choice B rationale:
A dark red appearance of the penis could indicate a complication such as infection or necrosis, which would require medical attention.
Choice C rationale:
The Plastibell is not removed manually; it falls off naturally within 5 to 8 days.
Choice D rationale:
A snug diaper could cause pressure and discomfort on the surgical site; it’s recommended to fasten the diaper loosely.
The Plastibell circumcision technique is one of the most common methods of newborn circumcision. It involves placing a plastic ring under the foreskin and tying a suture around it to cut off blood flow. The foreskin then falls off naturally with the ring in seven to 10 days.
The correct answer is A. The nurse should include that “yellow exudate will form at the surgical site in 24 hours” as part of the teaching to the parents. This is because the yellow exudate is a normal sign of healing and should not be confused with infection.
The other options are incorrect because:
b. The parents should notify the provider if the end of the baby’s penis appears black, not dark red. This could indicate that the ring is too tight and is cutting off blood supply to the glans.
c. The Plastibell will not be removed 4 hours after the procedure. It will stay on the penis until the foreskin falls off naturally in seven to 10 days.
d. The newborn’s diaper should be loose, not snug. This is to prevent the ring from being dislodged or rubbing against the diaper.
