21
Q

Benefits of using dorsum of hand to cannulate?

A

Easier access
Less arteries and nerves
Easier to see and palpate veins
Movement not constricted therefore less liklely to dislodge cannula

22
Q

Cons of using dorsum of hand?

A

Vasoconstriction of veins due to hands being cold
considered more painful
veins are smaller and more mobile

23
Q

Benefits of anticubical fossa to cannulate

A

Veins are better tethered (less mobile)
less painful
Less potential for vasoconstriction
veins are larger and easier to cannulate

24
Q

Why do we take patients ASA classification?

A

To establish a patients physical health classification and risk assess their suitability for IV sedation. If a patient is ASA III or above then consider referring to a hospital setting.

25
Q

List 3 signs a patient is suitability sedated?

A

Fully relaxed in the chair
Eyes closed but still able to respond to command
speech slurred
less talkative unless prompted
drooping of the eyelids

26
Q

Why do we record blood pressure at patient assessment?

A

Help establish ASA classification. For a baseline reading before treatment begins. To detect underlying health conditions like possible hypertension (high blood pressure)

27
Q

What can give a false pulseoximeter reading?

A

Finger probe falling off due to patient moving about
Dark coloured nail varnish or acrylic nails
cold hands (vasoconstriction) which causes blood vessels to shrink
blood pressure cuff and finger probe on the same side/arm
skin pigmentation

28
Q

Bradycardia?

A

Low heart rate

29
Q

Tachycardia?

A

High heart rate

30
Q

When will hypertension (HBP) not occur?

A

During anaphylaxis

31
Q

in what order does a drug move into, through and out of the body?

A

Absorption, distribution, metabolism, excretion

32
Q

What is the function of the respiratory system?

A

To provide the body with oxygen and dispose of carbon dioxide

33
Q

Clinical effects of benzodiazepines?

A

Anxiolysis
Anticonvulsant
Amnesia
Muscle relaxant
Anaesthesia
Respiratory depression
Sedative

34
