Q

Why would mobile need to be used?

A

The biggest reason why a mobile would be needed is because the patient is unable to come down to the department:

This can be due to many reasons such as:
Suction
Pacing
Level of consciousness
Traction
Monitoring
Ventilated

Q

Why is it essential that there is a valid reason for a mobile to take place?

A

If the reason is not valid it is taking away resources which could be essential somewhere else

17
Q

What are some appropriate clinical indications for a mobile x-ray?

A

Cardiac/respiratory arrest/distress
Decreasing SATs (oxygen saturation)
Placement or repositioning of tubes
Placement of lines
Trauma call (Resus)
Post surgery

18
Q

What body parts are more common and less common to be mobile xrayed?

A

Chest (most common)
Abdomen – Less common
Pelvis – trauma
C-spine – trauma
Law/upper limb – trauma
T/L spine – trauma, rare
Skull – very rare, not justified

Always follow department protocols

19
Q

How does the initial request go for mobile x-ray?

A

Phone calls/pager system
Must justify the mobile request
Why is it a mobile request?
Can it be done in department?
When is it needed?
Request form!

20
Q

What are the considerations you must be taken into Account before you set off for a mobile x-ray?

A

How many staff are needed?
Which mobile machine is closest?
Have you remembered the key?
Location of ward
Word access
How many other mobiles?
Accessories – phone pads, sandbags, grid?
Don’t forget the inverse receptor or a request card!
Infection control?

21
Q

How to achieve good Infection control of mobile machines?

A

Hand washing
Use of alcohol gel
Alcohol wipes
Cleaning of mobile machine
Imaging plate covered
Use of accessories and cleaning them
PPE
Changing gloves etc between patients
Barrier nursing

22
Q

What radiation protection techniques to be seen in wards?

What other aspects of safe practice do we need to consider?

A

These for example questions in the PowerPoint I just can’t be bothered answering them right now yay

23
Q

What technique and considerations must be taking into account with mobile machines?

A

Patient positioning – EP or PE correct Erect are Supine
Easy slides
Nurse assistance
Specialised beds
Hyderabad – pressure sores + burns patients

24
Q

What considerations do you need to take into account in intensive care (ITU, ICU, HDU)?

A

Physiotherapy and chest care - It will be busy need to try and stay out the way I get in when you need to be
Sedation - Lots of people will be Unconscious
Communication - you will have to try and communicate with different members of staff from different teams as well as with patients who may not want to be very communicative
Infection control - It is essential that infection control is taking very seriously as people are very ill and have an increased risk to infection
Lines and catheters - You must be aware of all the lines of catheters to ensure that they are not trip hazards
as well as ensuring safety to the patient

25
Q

What should be considered in the coronary care unit (CCU)?

A

Cardiothoracic surgery, open chest, CABG, pneumonectomy
Infection control
Sedated?
Postop
Chest pains?

26
Q

What is essential to Do before any moving and handling Regarding catheters?

A

It is essential that The radiographer is aware of the location of the catheter before moving and handling to ensure the safety of the patient.

The bag can be located on patient or can be hooked onto the bed for ease of monitoring and emptying

27
Q

What must you Always keep in mind when working with patients who have catheters and sites of lines?

A

It is essential that you Are always aware of their positions especially during Moving and handling – As you don’t want to create further damage I want to make the imaging as efficient as possible 

Infection control!!!

28
Q

Name different lines and catheters that you can find on the wards:

A

CVP line - Central venous pressure– Internal jugular or subclavian vein

Chest drain – to relieve pressure or drain stuff

ET – Endotracheal tube and ventilator

Nasogastric tube – NG

Haemofiltration

Epidural

Peg feeds

Insulin pumps

Diamorphine pump

Hickman line, picc line

29
Q

What can be the result of an incorrectly placed NG tube?

A

Aspiration pneumonia

30
Q

What must you consider when a patient has an ECG line?

A

You must not remove an ECG line from A critical patient, but you Should think about the wire placement

31
Q

What can be the result of rotation in a chest x-ray?

A

The sternoclavicular joint won’t be equidistant which may give a false indication of lung parenchyma
