1

List the types of thermometers that can be used in practice

Digital- rectal, aural and oesophageal
Mercury
Biotherm

2

What are the advantages of digital thermometers?

Quicker to use
Smaller so more comfortable

3

Why aren't mercury thermometers commonly used?

Toxic within glass so easy to break
Need to be shaken down before use

4

Explain the biotherm thermometer

Tiny chip under scruff and when scanned shows temperature

5

Describe how to care for and store thermometers

Don't share between infectious patients
Store in original casing- digital
Store in cotton wool filled with disinfectant solution, dont use hot water as glass breaks- mercury

6

Where is the most reliable place to take temperature readings from?

Rectal

7

Describe how to take a rectal temperature

Lubricate thermometer and slowly insert in twisting motion
Hold thermometer flat and push dorsally so is touching top membranes to avoid faeces
Hold for 30-60 seconds, gently remove and clean
Record temperature and disinfect

8

Define hypothermia

Low body temperature

9

Define hyperthermia

High body temperature due to environment

10

Define pyrexia

Increase in body temperature due to infection

11

Define diphasic

Fluctuating temperature

12

What is the purpose of measuring blood pressure?

Provide information about cardiovascular function, cardiac output and blood flow

13

How to calculate blood pressure

Cardiac output x total peripheral resistance

14

What does systolic blood pressure measure?

Force heart exerts on artery walls each heart beat

15

What does diastolic blood pressure measure?

Force heart exerts on artery walls between heart beats

16

What does mean arterial pressure measure?

Average pressure in arteries in cardiac cycle

17

Dogs blood pressure range

131-154/75

18

Cats blood pressure

115-162/83

19

List the methods of recording blood pressure

Arterial catheter
Oscillometric measurement
Dopler technique

20

Describe how to measure blood pressure using arterial catheter

Place catheter in dorsal pedal, coccygeal or medial auricular artery and connect to DABP monitor
Connect fluid administration set to give 0.9% sodium chloride and pressurise fluid bag above systolic pressure to prevent backflow of blood
Pressure transducer is connected to monitor at level of the heart and to fluid system
Zero monitor to level of right atrium to pick put pressure changes as electrical signals to present a pressure wave

21

List advantages and disadvantages of arterial catheter to monitor blood pressure

Advantages- most accurate method, real time readings
Disadvantages- only used on critical patients due to invasiveness, costly, risk of haemorrhage and infection

22

Describe the oscillometric technique of blood pressure monitoring

Place blood pressure cuff on pulse site and ensure line of cuff matches artery. Cuff should be 1/3 width of limbs circumference
Inflate cuff and readings are automatically taken

23

List advantages and disadvantages of oscillometric blood pressure technique

Advantages- automated so less skill needed, can measure at timed intervals, less handling so lowers stress
Disadvantages- Less accurate when under 5kg, moving or has cardiac issues

24

Explain the process for the dopler technique of measuring blood pressure

Place cuff proximal to probe
Clip fur around pulse site and clean with surgical spirit then apply ultrasound gel
Place dopler probe on clipped area and move until pulse is found and heard
Inflate cuff with sphygmomanometer until no sound is heard then slowly deflate and record the measurement of when sound returns which is the systolic pressure
Repeat and take average, completely deflating cuff between readings

25

List advantages of dopler technique

Advantages- easy, affordable, can be used on all animals

26

Where are palpable pulse sites found

Femoral- medial aspect of femur
Digital- palmer aspect of carpus/inside of wrist
Tarsal- medial aspect of tarsus/middle of ankle
Lingual- ventral aspect of tongue

27

Define sinus arrhythmia

Increased pulse on inspiration and decreased pulse on expiration

28

Define dysrhythmia

Pulse rate lower than heart rate

29

Define hyperdynamic pulse

Strong bounding pulse

30

Define trachycardia

Increased pulse rate
