Exam 15: Fluid and Acidbase Balance

Energy cannot be created or destroyed, but it can be transformed from one form of energy into another.

Match the heat exchange terms labelled a. through d. with their descriptions. a.convection b.evaporation c.radiation d.conduction -heat loss by means of conversion of water from a liquid to a gaseous state

Match the terms labelled a. through g. with the correct characteristic. a.hypothermia b.obesity c.frostbite d.hyperthermia e.anorexia f.heat stroke g.heat exhaustion -morbid fear of becoming overweight

Profuse sweating occurs during heat stroke as the body's temperature climbs rapidly.

A fever augments the inflammatory response and therefore inhibits the multiplication of ____________________ microorganisms.

Match the terms labelled a. through g. with the correct characteristic. a.hypothermia b.obesity c.frostbite d.hyperthermia e.anorexia f.heat stroke g.heat exhaustion -freezing of tissues as a result of cold exposure

Upon exposure to heat, skin vasodilation occurs, which increases the temperature gradient between the skin and environment, thus promoting heat loss.

Which of the following will happen if more energy is contained in the food eaten than is expended?

Oral temperature is lower than the core temperature.

Skin vasoconstriction reduces the temperature of the skin.

Heat exhaustion is accompanied by extensive sweating, whereas heat stroke is characterized by an absence of sweating.

The temperature-sensitive receptors that monitor skin and core temperatures are termed ____________________.

Upon exposure to cold, which of these conditions does NOT occur?

Which of these statements correctly describes leptin?

As the level of circulating, active thyroid hormone increases, the BMR increases correspondingly.

The minimal waking rate of energy expenditure determined under standardized conditions is known as the ____________________.

Match the terms labelled a. through g. with the correct characteristic. a.hypothermia b.obesity c.frostbite d.hyperthermia e.anorexia f.heat stroke g.heat exhaustion -state of collapse resulting from reduced blood pressure brought about as a consequence of overtaxing the heat loss mechanisms

____________________ work refers to the energy expended by contracting skeletal muscles to accomplish movement of objects or the body in the external environment.

Which of these statements does NOT correctly describe obesity?

All causes of hyperthermia are pathological and fatal.
