A nurse in a healthcare provider’s office is caring for a patient who is at 34 weeks of gestation and at risk for placental abruption.
The nurse should recognize that which of the following is the most common risk factor for abruption?
Cigarette smoking.
Hypertension.
Blunt force trauma.
Cocaine use.
The Correct Answer is B
Choice A rationale
While cigarette smoking can increase the risk of many complications during pregnancy, including placental abruption, it is not the most common risk factor. Smoking can cause constriction and damage to the blood vessels in the placenta, but other factors, such as hypertension, are more commonly associated with placental abruption.
Choice B rationale
Hypertension is the most common risk factor for placental abruption. High blood pressure can cause damage to the blood vessels in the placenta, leading to abruption. Chronic hypertension, gestational hypertension, and preeclampsia can all increase a woman’s risk of experiencing a placental abruption.
Choice C rationale
Blunt force trauma, such as that experienced in a car accident or a fall, can cause placental abruption, but it is not the most common risk factor. Any trauma to the abdomen during pregnancy should be evaluated by a healthcare provider to assess for potential complications, including placental abruption.
Choice D rationale
Cocaine use can increase the risk of placental abruption. Cocaine causes intense vasoconstriction, which can compromise the blood flow to the placenta and lead to abruption. However, it is not the most common risk factor for this condition.

Correct Answer is D
Explanation
-
G (Gravida): Total number of pregnancies → 4
-
T (Term births): Delivered at 37 weeks or more → One (39 weeks) → T = 1
-
P (Preterm births): Delivered between 20–36 weeks → Twins (34 weeks, 1 pregnancy) + One at 35 weeks = 2 preterm pregnancies → P = 2
-
A (Abortions): Pregnancies ending before 20 weeks → 0
-
L (Living children): One from term birth, two from twins, and one from the other preterm = 4 living children → L = 4
