A clinician defines a fetus at risk. Which single description is correct?

Answer: A. One in which factors prevent the fetus achieving its full growth/wellbeing potential

Definition of a fetus at risk

The concept of the 'fetus at risk' frames antenatal and intrapartum surveillance.

Definition

• A fetus at risk is one in which factors affect the fetus such that it is unable to achieve its full growth (or wellbeing) potential.

Examples of risk factors

• Placental insufficiency / growth restriction, maternal disease (hypertension, diabetes), post-term pregnancy, infection, abnormal liquor volume, and multiple pregnancy.

Approach

• Identify the cause of any fetal hypoxia and correct it, or deliver before acidosis develops.
• Monitor with AFI, Doppler, CTG and the biophysical profile.

So a fetus at risk is one prevented from reaching its full potential.
