for the Practical Nurse Comprehensive Questions
with Verified Answers and Detailed Rationales
Question 1
What is evaporation and what would you do with the newborn
experiencing evaporation?
• A. Conversion from liquid to vapor; dry newborn quickly and dry and
cover the head of the newborn
• B. Transfer of heat to a cooler surface; pre-warm radiant warmer and
stethoscope
• C. Loss of heat to surrounding cooler air; place crib away from windows
and vents
• D. Loss of heat to surrounding cold environments; place crib away from
cold walls
Correct Answer: A. Conversion from liquid to vapor; dry newborn quickly
and dry and cover the head of the newborn
Rationale:
1. The source indicates A is correct.

2. Evaporation occurs when liquid on the skin turns to vapor.
3. Drying the newborn immediately prevents heat loss.
4. The head should be covered because it has a large surface area.
Question 2
What is conduction and what would you do with the newborn
experiencing conduction?
• A. Conversion from liquid to vapor; dry newborn quickly
• B. Transfer of heat to a cooler surface; pre-warm radiant warmer and
stethoscope before using; place scale paper and place warm blanket on
other surfaces
• C. Loss of heat to surrounding cooler air; place crib away from windows
and vents
• D. Loss of heat to surrounding cold environments; place crib away from
cold walls
Correct Answer: B. Transfer of heat to a cooler surface; pre-warm radiant
warmer and stethoscope before using; place scale paper and place warm
blanket on other surfaces
Rationale:
1. The source indicates B is correct.

2. Conduction occurs through direct contact with cooler surfaces.
3. Pre-warming equipment prevents conductive heat loss.
4. Using warm blankets on surfaces provides insulation.
Question 3
What is convection and what would you do with the newborn
experiencing convection?
• A. Conversion from liquid to vapor; dry newborn quickly
• B. Transfer of heat to a cooler surface; pre-warm equipment
• C. Loss of heat to surrounding cooler air; place crib away from windows
and vents
• D. Loss of heat to surrounding cold environments; place crib away from
cold walls
Correct Answer: C. Loss of heat to surrounding cooler air; place crib away
from windows and vents
Rationale:
1. The source indicates C is correct.
2. Convection occurs through air currents.
3. Drafts from windows and vents cause convective heat loss.
4. Positioning the crib away from air sources prevents this loss.

Question 4
What is radiation and what would you do with the newborn
experiencing radiation?
• A. Conversion from liquid to vapor; dry newborn quickly
• B. Transfer of heat to a cooler surface; pre-warm equipment
• C. Loss of heat to surrounding cooler air; place crib away from windows
• D. Loss of heat to surrounding cold environments; place crib away from
cold walls; wrap newborn warmly
Correct Answer: D. Loss of heat to surrounding cold environments; place crib
away from cold walls; wrap newborn warmly
Rationale:
1. The source indicates D is correct.
2. Radiation is heat loss to cooler objects not in contact.
3. Cold walls absorb radiant heat from the newborn.
4. Wrapping the newborn provides insulation.
Question 5
What 3 vessels should the umbilical cord have?
• A. Artery, artery, artery
