Quiz 7: Temperature control and hypothermia

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

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
