A fall in the body temperature:

Question 6

Body temperature is generally ___ early in the morning and __ in the afternoon or early evening following a day of activity.

Answer 6

lowest
highest

Question 7

Body temperature is generally lowest early in the morning and highest in the afternoon or early evening following a day of activity.

Answer 7

Diurnal Variations.

Question 8

Body heat is the result of __ ) therefore heat production is increased by exercise.

Answer 8

cell activity. (skeletal activity

Question 9

Oxidation and combustion of food release heat-producing energy. Ingestion of high-calorie energy-giving foodstuff increases the temperature due to food having a specific caloric yield (4.1 calories for 1 gram of CHO and protein and 9.3 calories for 1 gram of fat)

Answer 9

Specific Dynamic Action (SDA) of Food.

Question 10

Newborns and young children have___ body temperature than adults. The aged tend to have __ than young adults.

Answer 10

higher
lower temperatures

Question 11

• commonly used device to measure body temperature.

Answer 11

Thermometer

Question 12

is a silvery liquid metal used for this purpose because it expands when exposed to heat and rises as it expands in the narrow

Answer 12

Mercury

Question 13

• It has a glass bulb containing mercury and a stem.
• one end contains a bulb filled with mercury.
• outside of a glass tube (stem) marked with a scale for measurement.

Answer 13

Glass and Mercury Thermometer.

Question 14

Types of Bulb on Glass Thermometer:

Answer 14

Rectal thermometer – short, flat, rounded
Axillary thermometer – long and slender bulb
Oral thermometer – slightly longer than the rectal bulb

Question 15

are regarded as the fastest, most common, and most accurate type of thermometer. Readings are taken from under the tongue, from the rectum, or under the armpit. They are easily found in local pharmacies and can be used at home or in the hospital.

Answer 15

Digital thermometers

Question 16

These thermometers also read heat using infrared and are placed on the temporal artery. are also not as reliable as digital thermometers.

Answer 16

Forehead thermometers

Question 17

These thermometers can detect the presence of a fever in a patient; however, they do not give an exact temperature reading. They simply act as an indication that something might be wrong. To use them, you just place the strip on the forehead.

Answer 17

Plastic strip thermometers

Question 18

These thermometers are used predominantly in babies older than three months. They require the baby to be still for a couple of minutes and this can be a struggle. This means that sometimes the temperature can be inaccurate.

Answer 18

Pacifier thermometer

Question 19

These use infrared technology to get their temperature reading. are less accurate if there is too much wax in the ear it can give an incorrect reading. Despite being expensive, they are a lot easier to use on babies and young children, as it can be hard to get children to sit still for long enough while using digital thermometers.

Answer 19

Electronic or tympanic ear thermometers

Question 20

handheld electronic devices with an integrated visual display, designed for detecting heat energy. The key component of a thermal camera is a heat sensor attached to a special type of lens, which is then adapted to work alongside standard image-capture technologies

Answer 20

Thermal imaging cameras

Question 21

• Named after Gabriel Daniel Fahrenheit, a German physicist who invented the mercury thermometer in 1714.
• freezing point at 32 ºF, boiling point of water at 212 ºF

Answer 21

FAHRENHEIT SCALE (ºF)

Question 22

• The freezing point at 0 C. boiling point of water at 100 C.
• named after a Swedish scientist, Anders Celsius
• more widely used temperature scale in the Philippines

Answer 22

CELSIUS/CENTIGRADE SCALE (ºC)

Question 23

the most accurate and reliable index of internal body temperature but it could be uncomfortable to the patient. Advisable on the very ill, neurosurgical, and highly febrile patients.

Answer 23

• RECTAL/FROM THE RECTUM

Question 24

• most practical clinically preferred method. Reflects changing body temperature more quickly than the rectal method.

Answer 24

• ORAL/BY MOUTH

Question 25

least accurate, should be taken only when oral and rectal temperature is contraindicated.

Answer 25

* AXILLA/FROM THE ARMPIT

Question 26

use infrared sensors to pick up on infrared radiation that the body produces. Although infrared radiation is not visible, a person may be able to feel it as heat.

Answer 26

* Forehead Thermometers
