Q

What do you say to the patient before an ECG?

A
  • Explain the procedure- ‘I’ve been asked to take some recordings of your heart, this will involve me placing some stickers on your chest, arms and legs. I’ll then attach the stickers to some leads which are part of the machine. These will then take a recording of your heart. You shouldn’t feel any pain. The procedure will involve you being exposed down to your waste is that ok? I will also need to have access to your ankles. Would you like a chaperone?’
  • Gain consent and check allergies (to stickers)

Q

What do you say to the patient before cardiac monitoring?

A
  • Explain the procedure-‘this cardiac monitor will continually measure the rate of your heart. I am going to attach 3 little stickers to your chest, these will then attach to some leads which will attach to a monitor. Then we can monitor the trace of your heart. This will remain on for the rest of the day- you don’t have to stay still but if you need to get up and go to the toilet just let us know. If your rate increases then there will be little alarms that will go off which will let the nurses know. Any questions? I will need to expose your chest if that is ok? And would you like a chaperone?’
  • Gain consent and check allergies

22
Q

How would you explain what a peak flow is, why and when it should be done

A

• What is peak flow;
o a peak flow meter measures the maximum speed that a patient can exhale air from their lungs in litres per minute. A patient’s peak flow can be compared with normal expected values for someone of their age, sex and height and there are charts that can be used to work out normal values.
• Why they need to monitor their peak flow;
o In asthma, the airways become narrowed and this reduces the speed that air can move through them. Changes in a patient’s peak flow over time reflect changes in the severity of their disease and the effectiveness of their treatment. A peak flow diary is useful to guide doctors as to whether current asthma medication is working or whether a change in treatment regimen is needed. In this patient’s case, the GP wishes to see if there is any improvement in Peak Flow once the patient starts using a salbutamol inhaler, indicating that this treatment is effective in increasing air flow.
• When they should check their peak flow i.e. what times of day; How many exhalations are needed, and which result should be recorded?
o The student should explain to the patient that three readings should be taken every morning and every evening, before using their inhaler. The best of the three readings should be recorded in the Peak Flow Diary. It is common for morning readings to be lower than evening readings

23
Q

What do you say before showing the patient how to do a peak flow?

A
  • ‘today we will be doing a peak flow test on your lungs due to the problems you have been having with your asthma. We use it to assess the severity of your asthma and also to monitor the progress of your treatment and to see how it has been working. We need the best technique for the correct results. I will demonstrate and then let you have a go- does that sound ok?’
24
Q

Process of Peak flow

A
  • Peak flow meter;
    o Set pointer to 0
    o Use a disposable mouthpiece
    o Sit upright and hold meter horizontally
    o Make sure pointer moves smoothly along the scale
    o Take deep breath
    o Form tight seal around with mouthpiece with lips
    o Blow as hard and fast as you can
    o Note reading and reset pointer
    o Do 3 times and record highest value
  • Get patient to do it (change mouthpiece) and check technique and show them how to record on flow chart
  • Check patient is ok and ask if any questions
25
Q

What do you say before performing the allens test?

A
  • so now im going to do a test on you which involves squeezing lightly on your wrist to check whether either of your two arteries area this wont be painful but let me know if you’re in any pain, am I okay to continue?
26
Q

Process of Allens Test

A
  • Ask the patient to make a fist.
  • Find pulse on both sides
  • Using your fingertips, occlude the blood flow through the radial and ulnar arteries at the wrist.
  • Ask the patient to release the fist and observe the blanched appearance to the hand, while maintaining pressure on the arteries.
  • Remove pressure from the ulnar artery whilst maintaining pressure on the radial artery and observe the reperfusion of the patient’s hand. Observe whether all five digits are reperfused.
  • Repeat the process with the radial artery.
27
Q

what do you say before performing an ABG?

A

‘today I need to do a blood test which tells us about O2 levels in your blood. This is a bit different to blood tests you might have had before- it is taken from artery and not vein and also it is taken from your wrist and not further up your arm. It might be a bit painful but I’ll try and be as gentle and quick as possible. Also we will have to press on it for a lot longer afterwards too.’
- Gain consent

28
Q

equipment needed for ABG?

A
  • wipe
  • ABG needle
  • cotton wool
29
Q

process of ABG?

A

o Identify site and check for CI e.g. broken skin, no surgery on that arm? Preferred arm? No swelling or fistula in that arm?
o Clean skin and dry
oPunctures the radial artery at either 45 or 90 degrees and slowly advances the needle until it is sited intra-arterial (i.e. until you get flashback)

o Allows the syringe to fill with blood.
o Carefully withdraws needle and applies firm pressure to the puncture site
o Checks allergy status and secures cotton wool with tape
o Asks the patient to press firmly for a minimum of five minutes
o Ensures that air bubbles are expelled from the syringe and caps the sample
o Rolls or inverts the syringe immediately to mix contents with heparin
o States “I would analyse this sample immediately, or if there is any delay, I would put the sample in ice
o Dispose of sharp
- Check patient is ok
- Document results in notes- inc conc of flow rate of inspired O2, site used, result of Allen’s test, any complications, results of blood gas test etc.

30
Q
  • Q1) What two things would you do to monitor this patient’s response?

Q2) What range of oxygen saturation would you ideally aim to achieve?

A

A. Monitor oxygen saturation levels with pulse oximetry and
o B. Repeat the arterial blood gas analysis within one hour

o 88% – 92%

31
Q

what do you say before administering oxygen?

A
  • Introduce myself
  • Identifies patient correctly
  • ‘I’m here today to give you some O2 to try and reduce your breathlessness, I will also try and raise O2 levels in the blood because they are just a little bit low.’
  • consent
32
Q

Process of administering O2

A
  • select venturi mask
  • Identifies correct valve- the correct oxygen percentage (accept 24% (blue) OR 28% (white) as correct) (the white bit that attaches to the mask)
  • Identifies correct oxygen flow rate- the correct flow rate for the valve they have selected (24% = 2 l/min; 28% = 4l/min). (the ball thing on the wall)
  • Prescribes oxygen correctly on the prescription chart
  • Connect tubing to oxygen source and turn it on
  • Check patency/flow before applying mask to patient.
  • Make sure there is a snug fit for mask/apply it correctly
  • Check patients welfare
  • ‘I would document the procedure in the patients notes’
33
Q

Why would you use a Venturi mask over a rebreath

A

Rebreathe would lower the amount of oxygen so you’re not always sure the amount they’re breathing

34
Q

Why wouldn’t you want a pulse oximetry above 92% with a patient with COPD

A

They are physiologically compensated for lower O2 eg renal compensation so if you went above they would be alkalotic
