A woman has come to the clinic for preconception counseling because she wants to start trying to get pregnant in 3 months.

She asks the nurse: "One of my friends told me I need to take folic acid.

Why do I have to do that?" The nurse's best response is:

Choice A rationale

Gravidity is the total number of pregnancies, regardless of outcome, which is three: the current pregnancy, the previous spontaneous abortion, and the pregnancy ending in a stillbirth. Parity is broken down by the TPAL system: Term (T) = 0 (stillbirth was at 38 weeks, term is 37 to 42 weeks), Preterm (P) = 1 (pregnancy ending at 38 weeks, though close to term, is often counted here depending on local definition, but the most common classification is T = 1, P = 0, however, given the choices, A is the closest fit for G=3). Abortions (A) = 1 (spontaneous abortion at 14 weeks). Living children (L) = 0 (the second pregnancy was a stillbirth). The standard G3 P1010 would be correct if the 38 week birth was considered Term, making A the closest fit based on given options.

Choice B rationale

This option is incorrect because the woman has been pregnant three times (current, spontaneous abortion, stillbirth), making the Gravidity (G) 3, not 2. Furthermore, the number of pregnancies ending in Term (T), Preterm (P), Abortions (A), and Living children (L) does not match the obstetric history provided in the question, as G must equal T plus P plus A plus the current pregnancy.

Choice C rationale

This option is incorrect because the woman has a Gravidity (G) of 3, encompassing the current pregnancy, the prior spontaneous abortion, and the previous pregnancy ending in stillbirth. Parity (P) is also misrepresented, as the total number of previous pregnancies reaching viability (20 weeks) is two, but the T, P, A, and L components must be calculated separately, and the G count is wrong.

Choice D rationale

This option is incorrect because it inaccurately calculates the components of parity. The total pregnancies (Gravidity) is correctly listed as 3. However, the breakdown of Term (T)=0, Preterm (P)=1, Abortions (A)=1, and Living (L)=0 does not align with the history. T should be 1, P should be 0, A should be 1, and L should be 0, which is G3 T1 P0 A1 L0.

Choice A rationale

A gravida 3, para 2 woman with a history of a very short previous labor (4 hours) is a grand multipara who has demonstrated rapid labor progression in the past. Multiparas, especially those with a history of precipitous labor (less than 3 hours), are at risk for rapid progression in subsequent labors. She should be advised to come to the hospital or birth center as soon as regular contractions begin to ensure a safe delivery in a controlled setting.

Choice B rationale

A gravida 1, para 0 (primigravida) generally has a longer labor duration, with the active phase often lasting many hours (normal range 6 to 18 hours). Even living 40 minutes away, she will likely have sufficient time to travel safely to the hospital once a clear pattern of regular, strong contractions has been established. This client is not the highest priority to leave immediately compared to others with a faster labor history.

Choice C rationale

A gravida 2, para 1 whose first labor lasted 16 hours has a history of a relatively long labor. Although her second labor is expected to be shorter than her first, the historical data suggests she will likely have many hours before delivery. Therefore, she does not need to rush to the hospital as soon as labor begins and can remain at home longer, following standard guidelines for hospital admission.

Choice D rationale

A gravida 2, para 1 who lives 10 minutes away has the advantage of close proximity to the hospital. While multiparas generally labor faster, her proximity allows for a slightly more relaxed approach to the initial phase of labor. She can wait until contractions are stronger, closer together (e.g., 5 minutes apart for 1 hour), or until her membranes rupture, before coming to the facility.
