A) Measurement of body temperature

1. Incorrect: The temperature recorded will be higher giving false reading.

2. Correct: The patient’s mouth must be kept closed in order to hinder cooler air from

entering the mouth affecting the temperature reading.

3. Incorrect: The medical assistant has to lubricate the thermometer so that it can be easily

inserted into the delicate rectal mucosa to prevent irritation.

4. Incorrect: It should be followed by circled capital A. The * is the degree symbol.

5. Correct: The fecal material is not perceived medical waste.

6. Incorrect: the medical assistant should not touch the probe cover since this can transfer

micro-organisms from the medical assistant to the patient.

Tympanic membrane thermometer

1. Incorrect: The dirty probe lens will give false temperature reading which are low.

2. Correct: This process will enable the sensor to get clear images of the tympanic

membrane. As a result correct temperature readings are taken.

3. Incorrect: The failure to seal the ear canal opening will allow cooler air to enter the ear

giving false reading which are low.

4. Correct: this will lead to accurate temperature leading as the probe is correctly positioned

to optimize the sensor’s view of the membrane.

5. Incorrect: at least 60 minutes are required for the aural temperature to stabilize.

Temporal artery thermometer

1. Correct: Clean or undamaged probe lens will give correct temperature reading.

2. Correct: The hair may trap body head giving high false temperature reading.

3. Correct: The thermometer will scan the peak temperature when the scan button is

depressed. It is advisable to hold the probe flat against the forehead. This will ensure

temporal artery is correctly scanned.

4. Incorrect: the thermometer will record false low temperature

5. Incorrect: the forehead has to be scanned as temperature may give error in the

temperature reading.

6. Incorrect: this activity can damage the thermometer.

93.2 -97 - hyperpyrexia

99 – 100.4 – low-grade fever

100.4 -105.8 - pyrexia

105.8 – 109.4 - hyperpyrexia

d) Pulse and respiratory rates

1. before vigorous exercise: 70 bpm

2. After vigorous exercise: 106 bpm

3. Taking part in the vigorous exercise the pulse rate increases.

e) Pulse oximetry

1. The nail polish should be removed using polish remover to hinder false low temperature

reading. The nail polish affect the transmission of light through the fingers.

2. Take the measurements from area that is not affected by motion for instance the toe. The

motion will affect the travel of light from the light emitting diode to the light detector and

hinders the probe to pick the pulse signal.

3. Wait until the patient is not coughing to take the measurement or use the areas less

affected by motion. The motion will affect the movement of light of from the light emitting

diode to the light detector preventing the probe from picking the pulse signal.

4. Prevent light from reaching the hand or the probe. The light will give incorrect reading as

it may be recorded by the light detector of the probe affecting the reading.

5. Take the reading from a different area such as the earlobe. The areas should be aligned to

enable light to be transmitted to the LED to the light detector giving wrong reading.

6. Take the reading from the earlobe as it has poor blood flow. Poor blood flow makes the

pulse to become weaker making the oximeter to fail to obtain reading.

7. Request the patient to rub the hands together. Cold fingers may interfere with obtaining the

readings.

8. Find another area to take the reading. The artificial fingernail may coat the nail giving low

false reading.

9. Use washcloth to cover the probe. Light may give incorrect reading.

10. Use the oximeter on the patient’s finger. The blood flow will be reduced in case the cuff

inflates leading to loss of pulse signal.

11.

A) Pulse search indicator

b) Alarm messages

c) Pulse strength bar graph indicator

d) Adjustable volume control

e) SpO2% display

f) Pulse rate display

g) Low battery indicator

h) On/Off control

f. Blood Pressure Measurement

1. The blood pressure increases

2. The artery is compressed by the tight sleeve giving incorrect reading.

3. The blood pressure will be falsely high.

4. Large cuff will give false low reading.

5. The reading will not be accurate.

6. The reading taken will be falsely low.

7. There will be no effect on the blood pressure reading.

8. The brachial artery is compressed.

9. The stethoscope would touch the arm as the cuff is not up enough on the arm.

10. It will be difficult to read the scale.
