A nurse is caring for a client who is to undergo a biophysical profile. The client asks the nurse what should the nurse include.

Choice A rationale The Amniotic Fluid Volume (AFV), typically assessed as the Amniotic Fluid Index (AFI), is a key component of the biophysical profile (BPP). AFV reflects fetal kidney perfusion and function; reduced volume (oligohydramnios) can indicate chronic uteroplacental insufficiency, a critical factor in fetal well-being, influencing BPP scoring. Normal AFI is generally 5-25 cm. Choice B rationale Fetal gender is determined by the chromosomes inherited at conception (XX for female, XY for male). While identifiable via ultrasound, determining the gender is not a scored component of the standard biophysical profile, which focuses on five observable physiological parameters reflecting fetal oxygenation and central nervous system function. Choice C rationale Fetal neck translucency (nuchal translucency, NT) is a prenatal sonographic marker used during the first trimester (11 to 14 weeks) as a screening tool for chromosomal abnormalities, like Down syndrome (Trisomy 21). It is not a component of the biophysical profile, which is generally performed in the late second or third trimester to assess current fetal well-being. Choice D rationale Gross fetal body movements are a parameter of the BPP. These movements are controlled by the fetal central nervous system (CNS). Adequate movement (e.g., at least three discrete movements in 30 minutes) suggests a well-oxygenated CNS. Reduced or absent movements can indicate hypoxia or other neurological compromise, which impacts the BPP score. Choice E rationale Fetal breathing movements (FBMs) are assessed in the BPP. These are sporadic, rapid movements of the diaphragm reflecting the maturation and function of the fetal CNS. The presence of at least one episode of FBMs lasting ≥ 30 seconds in a 30-minute observation period indicates a non-hypoxic fetus and contributes positively to the BPP score.
