Quiz 2: Assessing gestational age and size at birth

Please choose the one, most correct answer to each question or statement.

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
