Test 7: Temperature control and hypothermia

  1. The body temperature of a newborn infant should be measured by placing a digital thermometer:
    • In the mouth
    • In the rectum
    • In the axilla (arm pit)
    • In the incubator
  2. The normal abdominal skin temperature in a newborn infant is:
    • 35.5–36.0°C
    • 36.0–36.5°C
    • 36.5–37.0°C
    • 37.0–37.5°C
  3. Newborn infants produce heat by:
    • Shivering
    • Kicking their legs
    • Sweating
    • Breaking down brown fat
  4. Heat production is poor in:
    • Preterm infants
    • Term infants
    • Postterm infants
    • Female infants
  5. Loss of heat to the surrounding air is called:
    • Radiation
    • Conduction
    • Convection
    • Evaporation
  6. The amount of heat lost by radiation is influenced by:
    • The temperature of the incubator
    • The temperature of the room air
    • The temperature of the walls and windows
    • The temperature of the doctor’s hands
  7. Wet infants lose heat by:
    • Conduction
    • Convection
    • Evaporation
    • Radiation
  8. Heat loss is excessive in infants born:
    • Underweight for gestational age
    • With an appropriate weight for gestational age
    • Overweight for gestational age
    • At term
  9. What type of subcutaneous fat prevents heat loss?
    • Brown fat
    • White fat
    • Yellow fat
    • Pink fat
  10. Hypothermia is defined as an axillary temperature below:
    • 37.5 °C
    • 36.5 °C
    • 30.5 °C
    • 25.5 °C
  11. What determines the correct incubator temperature?
    • The infant’s weight
    • The infant’s sex
    • The infant’s haemoglobin concentration
    • The Apgar score
  12. When is the oxygen and energy requirements of an infant lowest?
    • When the body temperature is above normal.
    • When the body temperature is normal.
    • When the body temperature is below normal.
    • The oxygen and energy requirements are not influenced by body temperature.
  13. Heat loss by radiation is best prevented by:
    • Woollen booties
    • Woollen leggings
    • A woollen jacket
    • A woollen cap
  14. How should a well newborn infant with a gestational age of 35 weeks and weighing 1500 g be nursed?
    • With the mother in the kangaroo care position
    • Under a radiant warmer
    • In a cot (bassinet) in the general nursery
    • In a special warmed room
  15. Which form of heat loss is reduced by a perspex heat shield?
    • Convection
    • Radiation
    • Evaporation
    • Conduction
  16. Cold infants usually have:
    • A blue tongue and blue feet
    • A pink tongue and pink feet
    • A pink tongue and blue feet
    • A blue tongue and pink feet
  17. Sclerema presents as:
    • Blue sclera
    • Oedema of the scalp
    • Oedema of the feet
    • A woody feel to the skin
  18. Hypothermia causes:
    • Anaemia
    • Proteinuria
    • Hyperglycaemia
    • Hypoglycaemia
  19. While a cold infant is being warmed, it is important to give:
    • Sedatives
    • Antibiotics
    • A diuretic
    • Extra energy
  20. Pyrexia is dangerous as it may cause:
    • Bleeding
    • Jaundice
    • Apnoea
    • Acidosis
