The nursery nurse identifies a newborn at significant risk for hypothermic alteration in thermoregulation because the patient is

Multiple Choice

A) large for gestational age.
B) low birth weight.
C) born at term.
D) well nourished.
Answer:
B) low birth weight.

Explanation:
Low birth weight and poorly nourished infants (particularly premature infants) and children are at greatest risk for hypothermia. A large for gestational age infant would not be malnourished. An infant born at term is not considered at significant risk. A well nourished infant is not at significant risk.

A volunteer at the senior center asks the visiting nurse why the senior citizens always seem to be complaining about temperatures. The nurses best response is that older people have a diminished ability to regulate body temperature because of

Multiple Choice
expand_more
A) active sweat glands.
B) increased circulation.
C) peripheral vasoconstriction.
D) slower metabolic rates.
Answer:
D) slower metabolic rates.

Explanation:
Slower metabolic rates are one factor that reduces the ability of older adults to regulate temperature and be comfortable when there are any temperature changes. As the body ages, the sweat glands decrease in number and efficiency. Older adults have reduced circulation. The body conserves heat through peripheral vasoconstriction, and older adults have a decreased vasoconstrictive response, which impacts ability to respond to temperature changes.

A) decreased respirations.
B) low pulse rate.
C) red, sweaty skin.
D) slow capillary refill.
Answer:
C) red, sweaty skin.

Explanation:
With hyperthermia, vasodilatation occurs causing the skin to appear flushed and warm or hot to touch. There is an increased respiration rate with hyperthermia. The heart rate increases with hyperthermia. With hypothermia there is slow capillary refill.
