CHAP 3 Techniques of measuringg the parameters of body health

Question 1

3.1 Body temp

What’s average temperature of a persons body?

Answer 1

36.9°C

Question 2

3.1 Body temp (Types of thermometer)

Clinical thermometer

Answer 2

• Measures body temperature
• Measures temperature in the range of 35°C to 42°C

Question 3

3.1 Body temp (Types of thermometer)

Laboratory thermometer

Answer 3

• Measures the temperature of liquids
• Measures temperature in the range of -10°C to 110°C

Question 4

3.1 Body temp (Types of thermometer)

Rectal thermometer

Answer 4

• Measures body temperature through the rectum

Question 5

3.1 Body temp (Types of thermometer)

Infrared thermometer

Answer 5

• Measures body temperature without having any contact with the body

Question 6

3.1 Body temp (Measuring Body Temperature with the Correct Technique)

Clinical Thermometer

Answer 6

1. Make sure the thermometer temperature is lower than 35°C before using. If the temperature exceeds 35°C, the thermometer should be shaken until the reading is lower than 35°C.
2. Place the thermometer under the armpit or in the mouth for about 2 to 3 minutes (or until a ‘beep’ sound is heard, if you are using a digital clinical thermometer).
3. Pull out the thermometer and record the reading.

Question 7

3.1 Body temp (Measuring Body Temperature with the Correct Technique)

Laboratory Thermometer

Answer 7

1.Cannot measure body temperature because the laboratory thermometer does not have a kink in the mercury tube.
2. When the thermometer is removed from the body (either from the mouth or the armpit) the temperature reading will go down quickly making the reading inaccurate
3. If the laboratory thermometer is used to measure body temperature, the reading must be taken when the thermometer is still in the mouth or under the armpit to ensure accuracy.

Question 8

3.1 Body temp (Measuring Body Temperature with the Correct Technique)

Rectal Thermometer

Answer 8

• usually used for infants less than 3 months old. Make sure that the thermometer used is labelled for rectal use.
  2. Clean the tip of the thermometer with alcohol.
  3. Dab some petroleum jelly on the thermometer tip to make it easier for the thermometer to be inserted into the infant’s rectum.
  4. Raise the infant’s legs and insert 1.5-2.5 cm of the thermometer into the infant’s rectum.
  6. Allow the thermometer to remain there until a ‘beep’ sound is heard and record the reading

Question 9

3.1 Body temp (Measuring Body Temperature with the Correct Technique)

Infrared Thermometer

Answer 9

1. Aim the thermometer on the forehead at a distance of about 5 cm from the individual (do not aim the thermometer directly or indirectly at the eyes).
2. Record the temperature.
3. Taking temperature with this thermometer is very quick.

Question 10

3.1 Body temp

Factors that can cause the body temperature to be above normal reading

Answer 10

• Infection ( Bacteria , Virus )

Answer 12

Blood pressure is the pressure applied by the blood on the walls of the blood vessels during blood circulation

Question 13

3.3 Blood pressure

What device is blood pressure measured by?

Answer 13

Sphygmomanometer
- the measurement unit for blood pressure is millimetres of mercury (mmHg)

Question 14

3.3 Blood pressure (measuring and recording blood pressure)

Systolic pressure meaning

Answer 14

Systolic pressure is the pressure that applied on the walls of blood vessels when the heart muscles contract

Question 15

3.3 Blood pressure (measuring and recording blood pressure)

Diastolic pressure meaning

Answer 15

Diastolic pressure is the pressure that applied on blood vessels when the heart muscles r at rest

Question 16

3.3 Blood pressure (measuring and recording blood pressure)

What’s the readings for systolic diastolic?
What’s a normal blood pressure reading?

Answer 16

• systolic/diastolic
• Normal blood pressure reading is 120/80 mmHg

Question 17

3.4 BMI

Body Mass Index (BMI) meaning
What’s the importance of knowing our BMI?

Answer 17

• measurement of body mass against height
• to determine whether we have a body mass problem or not

Question 18

Answer 18

Below 18.5 BMI = underweight
18.5 - 24.9 BMI = Desirable weight
25.0 - 29.9 BMI = Overweight
