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)
0427
0503
0603
0527
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):
- Add 1 year: July 27, 2023 becomes July 27, 2024.
- Add 7 days: July 27, 2024 becomes August 3, 2024.
- 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 D
Explanation
Choice A rationale
A newborn typically begins to void within 24 hours after birth, so not voiding within this time frame is not immediately concerning.
Choice B rationale
Acrocyanosis, or bluish discoloration of the hands and feet, is common in newborns, especially within the first few hours after birth. It is a normal finding and does not require immediate intervention.
Choice C rationale
A temperature of 37.5°C (99.5°F) is within the normal range for a newborn. Therefore, this does not require immediate attention.
Choice D rationale
Newborns typically pass meconium, the first stool, within 24 to 48 hours after birth. If a newborn has not passed meconium within 24 hours, it could indicate a problem such as meconium ileus, a complication of cystic fibrosis, or other conditions that might obstruct the bowel. This situation requires immediate attention and intervention.
Correct Answer is ["B","E"]
Explanation
Choice A rationale
Abundant lanugo, which is fine hair, is not typically seen in postmature babies. It is more common in babies who are born prematurely.
Choice B rationale
A positive Moro reflex is a normal finding in newborns, including those who are postmature, indicating a healthy neurological response.
Choice C rationale
Vernix, a white creamy substance that protects the baby’s skin in the womb, is usually absent or very scant in postmature babies.
Choice D rationale
Short, soft fingernails are not a specific sign of postmaturity. Newborns’ fingernails can vary, and they often grow quickly after birth.
Choice E rationale
Cracked, peeling skin is commonly seen in postmature babies. Their skin can often appear dry and wrinkled.
