A woman arrives at the clinic for a pregnancy test.

Her last menstrual period (LMP) was February 14, 2019.

What is the client’s expected date of birth (EDB)?

September 17, 2019.

November 21, 2019.

December 17, 2019.

November 7, 2019.

Answer and Explanation

The Correct Answer is B

Choice A rationale
Calculating from the LMP of February 14, 2019, the estimated date of birth using Naegele's rule would not fall in September.
Choice B rationale

Using Naegele's rule, adding 7 days to February 14 results in February 21, 2019, then subtracting 3 months, results in November 2019.
Choice C rationale
Naegele's rule calculates EDB by adding 7 days to the LMP and then subtracting 3 months. This does not lead to a November date.
Choice D rationale
While close, November 7 is not accurate. Naegele's rule would adjust from February 14, giving an EDB in mid to late November.

Correct Answer is A

Explanation

Choice A rationale
Quickening, the first fetal movements felt by the mother, typically occurs between 16 and 20 weeks of gestation, so she should expect to feel fluttering sensations within the next month.
Choice B rationale
At 15 weeks of gestation, it is too early for most first-time mothers to feel fetal movements. Quickening usually occurs between 16 and 20 weeks, so she has not missed the window.
Choice C rationale
While some fetal movements may be subtle, it is inaccurate to suggest that some babies are entirely quiet. Quickening is generally felt by most mothers between 16 and 20 weeks.
Choice D rationale
The baby is indeed moving, but fetal movements are usually not felt until 16 to 20 weeks of gestation in first-time pregnancies, so it is normal not to feel them yet at 15 weeks.

A. Since you’re in your second trimester, you can drink as much as you like. B. Since you’re in your second trimester, there’s no problem with having one drink with dinner. C. Because no one knows how much or how little alcohol it takes to cause fetal problems, the best course is to abstain throughout your pregnancy. D. One drink every night is too much. One drink three times a week should be fine.

Correct Answer is C

Explanation

Choice A rationale
Drinking as much as desired, even in the second trimester, can lead to fetal alcohol spectrum disorders. No safe amount of alcohol is known during pregnancy.
Choice B rationale
Despite being in the second trimester, no level of alcohol consumption is considered safe during pregnancy, as it poses a risk to fetal development.
Choice C rationale
The safest course is to abstain from alcohol throughout pregnancy as no specific amount has been deemed safe and it can cause irreversible harm to fetal development.
Choice D rationale
Even limiting alcohol consumption to three times a week poses a risk to fetal health, as any amount can potentially cause developmental issues.
