Test 2: Assessing gestational age and size at birth

  1. Gestation is measured from:
    • The day of conception
    • The day the mother first feels fetal movement
    • The first day of the mother’s last normal menstrual period
    • The day of the mother’s first developed symptoms of pregnancy
  2. What is the average gestational age at birth?
    • 37 weeks
    • 38 weeks
    • 40 weeks
    • 42 weeks
  3. An infant with a gestational age of 37 weeks is called:
    • Term
    • Preterm
    • Postterm
    • Low birth weight
  4. A preterm infant is defined as an infant with a gestational age:
    • Less than 35 weeks
    • Less than 36 weeks
    • Less than 37 weeks
    • Less than 38 weeks
  5. Postterm infants have a gestational age of:
    • 42 weeks or more
    • 41 weeks or more
    • 40 weeks or more
    • 38 weeks or more
  6. The gestational age can be estimated after delivery by:
    • Weighing the infant
    • Measuring the infant’s head circumference
    • Measuring the infant’s haemoglobin concentration
    • Examining the infant’s physical features and assessing the neurological behaviour
  7. Infants that are born preterm have an increased incidence of:
    • Meconium aspiration syndrome
    • Wasting
    • Hypothermia
    • Pyrexia
  8. Which of the following infants should have their weight measured after delivery?
    • Infants that appear to be preterm
    • Infants that are wasted
    • Infants that appear clinically ill
    • All infants
  9. Postterm infants are at an increased risk of:
    • Hyaline membrane disease
    • Anaemia
    • Feeding difficulties
    • Birth trauma
  10. Most newborn infants weigh between:
    • 2000 g and 2500 g
    • 2500 g and 4000 g
    • 3500 g and 4000 g
    • 4000 g and 4500 g
  11. Low birth weight infants weigh:
    • Less than 3000 g
    • Less than 2500 g
    • Less than 2000 g
    • Less than 1500 g
  12. Most infants have a birth weight that falls:
    • Above the 90th centile
    • Between the 10th and 90th centiles
    • Below the 10th centile
    • Below the 3rd centile
  13. Infants that are underweight for gestational age have a birth weight that falls:
    • Below the 90th centile
    • Between the 10th and 90th centiles
    • Below the 10th centile
    • Below the 3rd centile
  14. Overweight for gestational age infants are often born to mothers with:
    • Hypertension
    • Syphilis
    • Rubella
    • Diabetes
  15. Intra-uterine growth restriction usually results in:
    • Only weight below the 10th centile at birth
    • Both weight and head circumference below the 10th centile at birth
    • Only head circumference below the 10th centile
    • Postterm delivery
  16. Wasting in the newborn infant is usually the result of:
    • Infection
    • Fetal undernutrition in the last weeks of pregnancy
    • Preterm delivery
    • Maternal diabetes
  17. Loose, wrinkled, dry skin and loss of muscle in an infant at birth suggests:
    • Wasting
    • Preterm delivery
    • Rhesus disease
    • Septicaemia
  18. Infants that are wasted at birth:
    • Are usually overweight for gestational age
    • Are always postterm
    • May be appropriate for gestational age at term
    • Are always low birth weight
  19. Wasted infants are at an increased risk of:
    • Hypoglycaemia
    • Birth trauma
    • Hyaline membrane disease
    • Infection
  20. Which of the following is the best predictor of problems in the neonatal period?
    • Gestational age alone
    • Weight alone
    • Weight for gestational age
    • Gestational age together with weight for gestational age
