Qs Flashcards
Before giving a patient contrast, what things would you need to consider?
T.P.A.P.D.B.e.C.
They need to have had a blood test done in the last 3 months
Previous contrast reaction?
Allergies?
PMH - heart disease? Kidney disease?
Diabetic? Do they take metformin? - metformin must be stopped 48hours before scan (risk of lactic acidosis if kidney function changes)
Blood thinners? - contrast flows quicker
eGFR level – how well kidneys filtering (needs to be approx 30, below 30 could result in kidney failure)
Creatinine level – how well kidneys working! - needs to be over 125
What would you do if you’re on a night shift and you don’t know the correct pathway for something?
Protocols
Ask the referring DR what it is they’re looking for - could give you clues as to which part of protocol to look into. Talk about your action plan to the DR to see if that would help them in gaining diagnostic information from the images?
Still unsure? Ask the radiologist
What steps would you take if you were planning on making a reject analysis programme?
Reject analysis is important in examining the reasons for images being rejected – helps minimise patient exposure to radiation from repeated examinations, improves efficiency and enhances image quality
Tell everyone in the department about the programme and ask them to participate
Explain the procedure and importance – that all
What would you do if a patient is brought to CT and there’s no pregnancy form signed and she can’t give you information on whether she is pregnant or not
There is a 10 day pregnancy rule for CT – high dose
See if the scan is not urgent – can they wait to come on period and return for CT
If the scan is urgent – check cerner for any information
(Outpatient)See if there’s any pregnancy tests in e.g. angio nurses
(A&E) they would have had blood test done – pregnancy would be stated here
(TRAUMA) – TTL decision due to patients best interest
You’ve given a patient contrast and the scanner breaks down. What do you do?
If scan started, end exam
If contrast is still going through, stop giving contrast and disconnect.
Check the scanner to see if it’s a known fault and you know how to fix it?
Turn it off and on?
If I can’t fix it. Consider if the scan be delayed - if so find another scanner
Before taking the patient to another scanner, consider speaking to a senior or radiologist about actions you’ll take because of the amount of contrast the patient will take and the impact on them - i.e. is it safe? Do I need to give contrast again?
Do scan, complete scan and DATIX the incident.
22 - What would you do if a student takes an x-ray and it’s not on PACS?
Check the computer the xray was taken on, have they sent it?
Check PACS on other computers- images may be there?
Try sending the image again
Check if there is PACS downtime?
Is it happening with other x-rays too?
Call ICT to report the issue
A new band 5 radiographer is doing a pelvis x-ray on a paed in A&E and has repeated the x-ray 3 times. You’ve noticed that the images produced are suboptimal. What would you do?
Tell the radiographer they should stop anymore exposures for that patient
Ask the referrer to check the x-rays and if they are ok with images and don’t think repeats are necessary?
Possibly also check with the radiologist to see if they require the x-ray to be repeated?
Speak to the staff member, see if they need additional training? Offer to help them?
A room shuts down in A & E. what would you do?
Turn the machine back on and attempt a test exposure
If the room doesn’t turn back on, put a sign on the room to say it’s not working and inform all colleagues via email
Inform superintendent
Report the room, get a reference number and date engineer will come to check
Inform A&E nurse in charge that we’re a room down
You are on a night shift - PACS and RIS go down, what do you do?
Inform all colleagues PACS and RIS is down and that we will be using down time procedure
If not planned downtime - report it to ICT OOH
If not already printed, print downtime forms
Check cerner for requests, print them and manually enter the patient details into the computer of the room doing x-ray in
Once finished with examination, on the downtime form, write patient details, exposure factors used and room examination done in
Keep all forms! Once the requests start coming through, ensure to delete all duplicate requests and send all images across.
Remember to complete all work so radiation incidents don’t occur in the form of double exposures.
All downtime forms should be given to PACS so they can assign images to requests.
PACS is down - tell the DR they need to come around to department to look at the x-rays on the computer console x-ray was taken and if portable x-ray, then image needs to be looked at on mobile machine.
What would you do if your colleague x-rayed the wrong patient?
Make them aware, ask them to double check with the patient their details and what examination they are having?
Be truthful to patient, apologise and explain to them what has happened
Inform the DR that the wrong patient has been x-rayed
Have PACS move the images to the patient that’s been x-rayed folder and it should still be reported on incase of incidental finding (write a comment on soliton explaining situation for the radiologist to also see)
You are working with a student in Generals and a patient goes into cardiac arrest - what do you do?
Send the student to call 2222 and to clearly state a patient has gone into cardiac arrest and you’ll need the crash team. Inform them of the location, gender, whether they’re an adult or paed.
While student is doing this I would start CPR and not stop until crash team are there
Ask the student to open door so crash team have access to room
DATIX of incident
Halfway through a theater case you notice staff not wearing lead. What do you do?
STOP exposing
Explain to the member of staff they need to be wearing lead
If they refuse, ask why they are not wearing lead? Answer their reason as to why they are not, and explain the importance of wearing lead to protect against radiation
If they are still refusing, let the surgeon know you will not be x-raying until the staff member wears lead
Once the case is finished, complete a DATIX and a radiation incident form. Then, speak to superintendent regarding the incident, because that person has probably been exposed to a lot of radiation since halfway through the case, I’ve realized they’re not wearing lead.
SOR wants to introduce the RED Dot system. What are the pros and cons?
PROS; Can reduce number of missed diagnoses (what radiographer sees referrer may not spot), can encourage radiographers to take closer look at x-rays to see if diagnostic enough? Can they repeat the image to make diagnosis easier? E.g. doing a better lateral ankle
CONS; radiographers that are not trained to report may flag something which is normal – worry the patient for no reason
How would you know if you’ve overexposed a patient? And what would you do?
Exposure index
DRL
Check system to see if exposure fault is yours
Inform RPS
Inform patient - honest, duty of Candour
QA
DATIX
ITU and RESUS are both waiting outside for CT. Who do you prioritise?
Both patients should be with drs
Check with DRS for urgency
Usually, ITU stable, DRs aware of PTs PMH and condition
Resus, new patient, unsure of injuries and clinical condition - golden hour - try to find out what’s going on to begin treatment ASAP
If I’m not alone, take RESUS patient and ask colleague to do ITU patient in next room scanner
ITU calls about a patient that needs imaging urgently, what steps would you take in CT?
See if there is a slot available/arrange a slot, get the doctors name and details
The patient will most likely be in a bed, ask if the patient is intubated, ask for any infection precautions and if the patient already has a cannula that is working, ready for use if needed.
If the patient is having a contrast scan, ask for the creatinine and eGFR level.
Ensure the scan has been vetted. (unless it’s a head or KUB - we can scan)
Inform colleagues of the ITU patient coming and prepare the room for them.
How would you go about imaging a confused patient for a CT head?
Ensure there is an escort with the patient (nurse or doctor).
If the patient is non-compliant, ask the nurse or DR to help and assist. If it’s unsafe, send the patient back. They may need to give sedation before attempting again. Ensure a note is put on soliton, to say it was unsafe to do the scan and you did not proceed.
However, If the patient is slightly confused, with the escort’s assistance, position the patient safely, explaining the instructions to them.If still confused, apply the safety belt and ensure they are safe before leaving them in the room.
Keep observing the patient while scanning to ensure unnecessary radiation is not given
What are the hounsfield units for bone, water and soft tissue?
Bone = +1000 to +3000 Air = -1000 Water = 0 Soft tissue = 100 to 300
In CT, what is the arterial and portal venous phase?
The early arterial phase offers optimal vessel demarcation and allows the detection of vascular pathology:
Arterial phase is when contrast is injected intravenously, it goes to the IVC, then to the right atrium and then to the right ventricle. It will then pass through the pulmonary arteries and into the lungs and into the aorta. From here we will scan roughly 17 seconds, where the contrast goes from ascending aorta to the descending aorta which highlights the vessels as well as arteries.
Portal venous phase is where the contrast goes from the aorta to the liver via the hepatic arteries then comes back to the IVC. This phase is roughly 70 seconds.
What would you do if your colleague was on the phone while a student brought a patient into the room?
Go to my colleague and ask them if they were supposed to be supervising the student?
Ask them if they would like to switch roles? I could take the call for them so they can continue supervising the student, or I could supervise the student while they continue on the phone.
If asked to supervise the student. I would introduce myself to the patient, let them know I’m supervising the student, ask to be excused for a minute, go through the request form with the student making sure the request is justified and check for previous x-rays on PACS.
Allow the student to resume and continue supervising the student.
Speak to colleague and let them know that it’s best to do one thing at a time to avoid mistakes and radiation incidents from happening - either supervise student or answer phone and don’t let student bring patient in.
How would you deal with a colleague who is not practicing safety regulations?
Speak to them. Ask if they were aware that they’re not practicing safety regulations.
If it was a genuine error, inform them and direct them to read the appropriate guidelines
Ask them if there’s anything in their personal life which is affecting their work and explain the importance of following safety regulations and consequences of not doing so
If this is happening consistently, inform the superintendent. They will need to have a meeting to ensure safe practice is carried out
If safety is not followed - such as radiation incident – DATIX
What would you do if a patient suffers a contrast reaction
Depends if it’s a mild, moderate or severe reaction
Get the drugs box and call for help. If it’s a severe reaction e.g. affecting breathing etc. call 2222 and get the crash trolley. Ensure the patient is breathing!
If it’s just a reaction, give the patient antihistamine which should be in the crash trolley and the drug box located in the room.
While help is coming, ensure you observe the patient. If their sats are lower than 96 - give them oxygen
Ask a radiologist to see the patient
Observe the patient and once the patient feels better, give them after care advice and any leaflets on after care. Advise them on what to do if things get worse - usually go to A&E
DATIX and leave note on RIS, let referrer know
You realise your colleague is scanning under the wrong name - what do you do?
Ensure it is the correct patient that needed to be scanned, then inform colleague of their mistake
If images have already been sent to PACS, let the DR know. Label the image with the patient’s correct details and contact PACS immediately to move the images to the correct folder.
Ensure the correct image is in the correct folder and the other image has been removed from the incorrect folder.
If this happens OOH, let the referring DR know. Label the images correctly and email the PACS team to assign the correct images to the correct patient folder ASAP.
It is vital to do this to ensure no misdiagnosis or harm is caused by incorrect treatment from the team.
How would you ensure radiation protection and reduce patient dose in fluro?
P.CRUEL SPARE
Lead gowns
Positive ID check
Radiation badges
Use of lead skirt/screen
Ensure warning signs are working
Carry out monthly QA
Reduce magnification - patient and detector have minimal distance to reduce scatter
Always expose on low setting
Ensure correct protocol is chosen
Removal of grid for children
Pulsed fluoro setting instead of continuous
Screening instead of acquiring images
A patient wants to complain about a colleague - what do you do?
Listen to the patient’s issues carefully to ensure the complainant’s real concerns are being explored - not what you perceive them to be
Once the issue is identified, and I can understand the reason why my colleagues actions may have angered the patient- e.g. if it’s a rule we have in the trust e.g. not allowed to take photo of the x-ray I would try to explain to the patient in a calm manner the reason behind it.
Then I would ask if there’s anything you could do to help? Anything that would make the patient’s experience better? E.g. if they want a copy of their x-ray they can fill a form in and we can put their x-ray onto a CD
I would then still give the patient the option to formally complain and refer them to the PALS service.Patient Advice and Liaison Service (PALS)
You see a student underperforming, how would you help them?
It’s important to help a student that is underperforming not only for their development into a competent radiographer but also for patient safety
Take the student aside, speak to them privately, ask them how they’re finding their training, ask them if they think they are struggling with anything? LISTEN to them and give time to share their issues
Their underperformance could root from many things e.g. personal matters, financial physical or health matters, loss of confidence or stress
Once the issues are identified, I’d help to find a solution e.g. if it’s something radiography related i.e. they’re not understanding a concept I would put time into teaching them and possibly in different ways to help them understand. If it’s an external issue e.g. stress of uni and placement, i would suggest them ways they can cope with the stress, how they can manage their time so it’s less stressful
Finally, I would help the student set goals depending on their issue, so that the outcome is measurable and we can see if it has actually helped them
You see an angry patient at the reception, how would you deal with it?
Take patient to private area
Listen to the patients concern/empathise with them
Speak in calm manner
Ask what you can do to help them/solve the problem?
If there is a reason behind their anger e.g. waiting times? Explain why they have had to wait
Find the best person they can speak to if I can’t do anything for them
Offer patient advice – they can speak to PALS
