Q

What are vital signs?

A

The measurement of a number of physiological parameters.

These include temperature, pulse, respiratory rate, blood pressure and oxygen saturations. These can be used to help calculate a patient’s NEWS score.

Q

How do you take pulse manually (without pulse oximetry device)?

A

Palpate the pulse for 30 seconds and multiply result by two. If the pulse is irregular, take pulse for one full minute. (If this is the first time the patient’s pulse has been taken it should be palpated for a full minute.)

Q

Describe taking blood pressure procedure

A
  1. Place cuff
  2. Place stethoscope over brachial artery and palpate pulse
  3. Inflate cuff until you can no longer hear pulse
  4. Slowly deflate cuff at rate of about 2mmHg/second
  5. Listen with the stethoscope and simultaneously observe the sphygmomanometer. The first knocking sound (Korotkoff) is the subject’s systolic pressure (when you can hear pulse again)
  6. Continue to deflate the cuff, listening for when sounds disappear –> This is the DIASTOLIC PRESSURE (e.g. 120/80)

16
Q

What is pulse oximetry? How is it performed?

A

Pulse oximetry is used to measure oxygen saturations by the use of a probe placed most commonly on the finger.

The probe monitors the percentage of haemoglobin in arterial blood that is oxygen-saturated.

17
Q

What should ox sat be in healthy patients?

A

>95%

18
Q

What is expected ox sat in patients with respiratory diseases?

A

88-92%

19
Q

What may give falsely low readings in pulse oximetry?

A
  1. Nail polish
  2. Cold extremeties
20
Q

What is used to measure peak expiratory flow?

A

Peak flow meter with disposable mouth piece

21
Q

How is peak expiratory flow measured?

A
  1. Check that the gauge on the peak flow monitor is moved to zero.
  2. Peak flow monitor should be held horizontal
  3. Take a deep breath before blowing as hard and fast as possible into the mouthpiece (sealed lips around mouthpiece)
  4. Ask the patient to repeat the process three times and record the best of these results on the appropriate charts/paperwork.

If the patient is to record their peak flow at home, ask them to do so at the same time of the day as there is a diurnal variation.

22
Q

If partial obstruction is supsected during choking, what should yoy encourage the patient to do?

A

Cough while leaning forward

23
Q

What may indicate complete obstruction during choking?

A

If patient cannot vocalise response to ‘are you choking?’

24
Q

How do you deal with complete obstruction?

A

Back slaps:

  1. Remove obvious debris from mouth, including loose dentures
  2. Stand to side and slightly behind patient
  3. Support them by placing one arm across their chest and lean them forward
  4. Give up to five sharp back slaps between their scapulae with heel of your hand
  5. After each slap, check their mouth for dislodged obstruction
25
Q

What should you do if back slaps are ineffective?

A

Carry out up to 5 abdominal thrusts:

  1. Stand behind patient and put your arms around the upper part of their abdomen
  2. Lean patient forward
  3. Clench your fist and place just beneath their sternum
  4. Grasp your fist with your other hand
  5. Pull sharply upwards and inwards in order to expel air from lungs and so dislodge obstruction
26
Q

If abdominal thrusts fail and patient loses consciousness, what should you do?

A

CPR (starting wth 30)

27
Q

What sample is needed during urinalysis?

A

Mid stream

28
Q

What should you check for when checking sample during urinalysis?

A
  1. Note for clarity, particles, and colour before removing lid of container
  2. Remove lid of container and check odour
  3. Check multistix container is intact and in date. DO NOT use if stored in humid environment or if out of date as accuracy of results cannot be guaranteed
29
Q

How is urinalysis performed?

A
  1. Dip test strip into urine to wet all the test zones (no more than one second)
  2. Remove strip and drag the edge of the strip along the rim of sample bottle to remove excess
  3. Replace lid
  4. Take note of the time and compare test zones on strip against those on the multistix container at the appropriate time. BE ACCURATE IN YOUR TIMING
  5. Note any abnormalities
  6. Dispose of waste appropriately. (Urine down sluice or toilet, container into clinical waste bag, fold test strip inside gloves as you remove them)
  7. Wash hands
  8. Record results
30
Q

What is the correct way to open the airway in a patient you suspect has a neck injury?

A

Jaw thrust

31
Q

What is jaw thrust?

A

An alternative manoeuvre for bringing the mandible forward and relieving obstruction by the tongue, soft palate and epiglottis. It is mainly used in suspected cervical spine injury when excessive head tilt could potentially cause spinal cord damage.

32
Q

What is the correct order of sequence for Adult Basic Life (BLS) algorithm?

A
  1. Danger (to yourself)
  2. Response (of patient)
  3. Shout for help
  4. Open and assess airway
  5. Assess breathing and circulation
  6. If no signs of life –> call crash team on 2222, locate crash ttrolley and defibrillator OR call 999
  7. Chest compressions
  8. Attach defibrillator
33
Q

During In-Hospital Resuscitation, the person delivering chest compressions must be switched:

A

No more than every 2 minutes or earlier if tired

34
Q

Describe paediatric BLS algorithm

A

1Danger

Response

Shout for help

Open and assess airway

Assess for breathing and circulation – no signs of life

5 rescue breaths

Chest compressions/rescue breaths: ratio 15:2

Call crash team on 2222 locate crash trolley and defibrillator /dial 999
