UPDATED ACTUAL Exam Questions and
CORRECT Answers
Thermoregulation for premature infants is influenced by all of the following except:
A. posture
B. small surface area to body mass ratio
C. Type and amount of accumulated fat - CORRECT ANSWER - B. small surface area to
body mass ratio
(Rationale: Thermoregulation for all infants is influenced by their large surface area to body
mass ratio, type and amount of accumulated fat, and posture. Premature infants lack the muscle
tone to maintain a flexed position, so they are particularly vulnerable to difficulties maintaining
temp,)
Which type of heat loss is reduced by holding an infant skin to skin?
A. convection
B. evaporation
C. Radiation - CORRECT ANSWER - A. Convection
(Rationale: When holding an infant skin to skin, the caregiver is providing heat and preventing
heat loss through convection.)
Which method is the most appropriate for assessing the temperature of a neonate?
A. Oral
B. Rectal
C. Axillary - CORRECT ANSWER - C. Axillary
(Rationale: Axillary temperatures are the most appropriate for a neonate because this method is
minimally invasive and temp readings are easy to obtain.)
,Where on the infant should a temperature probe be placed when using the servo mode on a
radiant warmer?
A. abdomen
B. right wrist
C. axilla - CORRECT ANSWER - A. abdomen
(Rationale: When using the servo mode on a radiant warmer, the temperature prove should be
placed on the infant's abdomen or flank. The pulse ox probe is placed on the right wrist. Axillary
temperatures are obtained using a thermometer, not a temp probe.)
Radiant warmers provide heat through which method?
A. convection
B. radiation
C. evaporation - CORRECT ANSWER - B. radiation
(Rationale: Radiant warmers provide heat through radiation. They should always be used in
servo mode to prevent overheating the infant.)
Which of the following is not true concerning radiant warmers?
A. risk of insensible water loss is decreased
B. increased risk of convective heat loss
C. Can be used in both the delivery room and the NICU - CORRECT ANSWER - A. risk
of insensible water loss is decreased
(Rationale: Radiant warmers may be used in both the delivery room and the NICU settings. This
thermoregulation equipment increases the risk of insensible water loss and convective heat loss.
Every effort should be made to keep the side rails up to minimize drafts.)
How is an incubator similar to a radiant warmer?
, A. heat source
B. humidity settings
C. Servo control - CORRECT ANSWER - C. servo control
(Rationale: As with the radiant warmer, an incubator also has servo control mode, but it has an
advantage over a radiant warmer in that the humidity can b controlled within the closed space.
Incubators use a convective heat source to keep the air surrounding the infant at a stable
temperature.)
How is heat lost through conduction?
A. water vaporizing from skin
B. close proximity to a cold window
C. cold hands of a provider - CORRECT ANSWER - C. Cold hands of a provider
(Rationale: Heat is lost through conduction when the infant comes into direct contact with a cold
surface such as a mattress, scale, or providers' hands. Water vaporizing from the skin is an
example of evaporative heat loss and close proximity to a cold window can lead to radiation heat
loss.)
Using humidified oxygen helps prevent heat loss through which method?
A. convection
B. radiation
C. evaporation - CORRECT ANSWER - C. evaporation
(Rationale: Evaporative heat loss occurs when water is vaporized from the skin including the
respiratory tract. For this reason, oxygen should always be humidified.)
Which of the following is a sign/symptom of hypothermia in a neonate?
A. apnea
