Question 1

Heat production is a result of energy being released in the body due to metabolism. What is lowest amount of energy required by the body to maintain vital function?&#10;A)Mitral valve rate&#10;B)Basal metabolic rate&#10;C)Heart rate&#10;D)42 units

Accepted Answer

The lowest amount of energy required by the body to maintain vital function is known as the basal metabolic rate. This is also the lowest amount of heat production by the body as a result of the chemical metabolism for only vital function.

Question 2

Which of the following can increase the basal metabolic rate?&#10;A)Hormones&#10;B)Exercise&#10;C)Eating&#10;D)All of the above

Accepted Answer

Hormones, exercise, and eating all require increased metabolism and energy production; in these functions, heat is produced in greater amounts and the basal metabolic rate goes up

Question 3

Which organ's large surface area has a primary role in heat regulation?&#10;A)Skin&#10;B)Heart&#10;C)Small intestine&#10;D)Large intestine

Accepted Answer

In order for the body to maintain conditions suitable for vital function, it releases energy in the form of heat. The skin helps this regulation because of its vast surface area and its ability to reduce the body's temperature through sweating.

Question 4

The loss of heat from the body occurs through:&#10;A)Radiation&#10;B)Conduction&#10;C)Evaporation&#10;D)All of the above

Accepted Answer

The loss of heat from the body in its attempt to regulate the appropriate temperature can occur through radiation, conduction, evaporation, and convection. All of these processes are based on the differences between the body's external and internal environments.

Question 5

The appropriate balance or normal temperature that the body attempts to maintain is approximately:&#10;A)96.8&#10;B)37&#10;C)98.6&#10;D)Both B and C

Accepted Answer

The approximate normal temperature of the human body is 98.6 °F or 37°C. It is important for providers to be aware of the differences between the metric and English system of measurement, as population changes and patients may refer to these values differently.

Question 6

Which organ is responsible for temperature detection and stimulation of sweating to help regulate the temperature and basal metabolic rate?&#10;A)Heart&#10;B)Skin&#10;C)Hypothalamus&#10;D)All of the above

Accepted Answer

The hypothalamus is responsible for the detection of temperature changes and stimulates the necessary bodily functions to help maintain homeostasis.

Question 7

The electrolyte concentration of sweat is:&#10;A)The same as the concentration in blood&#10;B)Higher in concentration than blood&#10;C)Lower in concentration than blood&#10;D)42

Accepted Answer

The electrolyte concentration of sweat is lower than it is in blood. This is because ducts on the sweat gland help reabsorb electrolytes to keep the body from becoming dehydrated.

Question 8

The process of blood flow that can increase the temperature of specific areas within the body on demand is known as:&#10;A)Vasoconstriction&#10;B)Vasodilation&#10;C)Erection&#10;D)All of the above

Accepted Answer

In order to increase blood flow, the capillaries widen in a process known as vasodilation. This increases blood flow and the temperature of the area in which the dilation occurs.

Question 9

One of the reasons for Emily's red skin is:&#10;A)Vasodilation&#10;B)Pooling of blood near the skin&#10;C)Both A and B&#10;D)Neither A nor B

Accepted Answer

When stress acts upon the body, it causes an increase in basal metabolic rate and temperature. The body reacts by causing vasodilation, which causes a pooling of blood in the capillaries of the skin's surface. This increases the process of sweating in an attempt to cool the body.

Question 10

Which of the following is the reason why John's body is better able to acclimate to temperature than his new baby?&#10;A)Age&#10;B)Size&#10;C)Composition&#10;D)All of the above

Accepted Answer

Infants have less ability to acclimate to temperature than do adults because of immature organ processing. In older adults, lessened ability is also noted as a result of failing organs. Body size and composition, specifically fat composition, can also be reasons for differences that different people have at being able to acclimate to temperature.

Question 11

The Stefan-Boltzmann law of physics refers to:&#10;A)The ability of the body to maintain temperature&#10;B)The process of heat transfer from high to low&#10;C)The process of the basal metabolic system&#10;D)The hypothalamus and its processes

Question 12

The process of capillary action to control temperature or react to control temperature is known as:&#10;A)Vasoactive control&#10;B)Vasopassive control&#10;C)Vasomotor control&#10;D)None of the above

Question 13

In the movie, Without a Paddle, three men are in a cave in a cold environment. Why does to the fact that they huddle together remain an important method of their survival?&#10;A)To maintain closeness&#10;B)To cause embarrassment of their friends&#10;C)To conserve their energy.&#10;D)None of the above
