Q

How do you examine a patient that you have assessed/taken a history for with abdominal pain?

A

Inspection: look for anaemia or jaundice, Grey-Turners and Cullens, ab distension, visible peristalsis, assess hydration

Q

If a patient presents with chest pain and does not require an immediate admission, where should they be referred to?

A

REFER TO CHEST PAIN CLINIC

- Urgent same day assessment: if suspected ACS but pain-free with chest pain in the past 12 hours and a normal ECG or chest-pain in past 12-72 hours with no complications

Q

What should you do if you suspect a patients pain is due to ACS?

A
  • Call 999

- Aspirin 300mg PO single loading dose chewed as antiplatelet

  • Maintain sats >94% using oxygen if pulmonary oedema or hypoxia
  • Offer morphine and antiemetics to relieve ischaemic pain
19
Q

What signs associated with acute chest pain should encorage you to admit a patient to hospital urgently?

A
  • Resp rate >30
  • Tachycardia >130
  • BP <90 <60 unless normal
  • Temp >38.5
  • Sats <92% or central cyanosis
20
Q

Where do patients with suspected STEMIs go when they get to the hospital?

A

If had an ECG in the ambulance they go straight to the cardiology catheter lab

21
Q

Why are patients given aspirin when ACS is suspected?

A

Lowers risk of myocardial infarction and stroke

22
Q

How should you manage a patient in primary care that presents with a suspected PE?

A

- Immediate admission for anyone who is haemodynamically unstable or pregnant/given birth in past 6 weeks

  • If none of these then do the Well’s criteria. If >4 admit to hospital for CTPA, if <4 offer D-dimer test with result in 4 hours with interim anticoagulation if takes longer. If test positive send for CTPA
23
Q

What interim anticoagulation is given whilst awaiting results of a D-dimer test for a likely PE?

A
  • Take FBC, renal and hepatic function, PT and APTT before commencing but do not wait for results

- Apixiban or Rivaroxiban first line for at least 5 days

  • If not suitable use LMWH followed by dabigatran for 5 days OR LMWH with Vit K antagonist for 5 days
24
Q

What are some differential diagnoses for acute shortness of breath in primary care?

A
  • Silent MI
  • Cardiac arrhythmia
  • Acute pulmonary oedema/heart failure
  • COPD
  • Asthma

  • Diaphragmatic splinting
  • Psychogenic breathlessness
25
Q

What are some questions you would ask a patient presenting with an acute presentation of SOB?

A
  • B.P
  • Pulse
  • Resp rate
  • Sats
  • ECG
  • PEFR
  • Temperature
26
Q

What features would warrant an admission to hospital when a patient presents to primary care with SOB?

A
  • If sats less than 94% oxygen should be given and monitored while awaiting transfer to hospital, unless at risk of hypercapnia
  • Only admit chronic breathlessness, e.g COPD, if exacerbation
27
Q

What would define whether asthma is severe asthma and life threatening asthma?

A
28
Q

What is the management for acute asthma?

A

OSHIT

- O2 5l to maintain sats between 94-98%

- Salbutamol 5mg or Terbutaline 10mg nebulised with O2

- IV hydrocortisone 100mg or 40-50mg PO prednisolone

  • Add ipratropium bromide 0.5mg/6h to nebuliser is life threatening
  • Magnesium sulfate and theophylline added by specialists

If life threatening hospital admission, if improved 24 hour follow up

29
Q

How do you manage an acute exacerbaton of COPD?

A
30
Q

  • Arrange urgent admission if patient has had more than one TIA, if patient lacks reliable observer at home or if patient has bleeding disorder/taking anticoagulant
  • Advise patient not to drive until review by specialist
  • After TIA have follow up with GP to discuss lifestyle changes and drug therapies
33

A

Acute unilateral facial nerve weakness or paralysis of rapid onset (<72 hrs)

Presentation: rapid onset, difficulty chewing, dry mouth, numbness in cheek or mouth, drooling, hyperacusis, facial weakness so drooping

Complications: eye injury, facial pain, dry mouth, psychological sequele, abnormal facial muscle contractions, hyperacusis

Q

How would you treat suspected anaphylaxis in primary care?

A

ABCDE assessment

  • IM adrenaline into anterolateral aspect of middle third of thigh
  • Repeat IM after 5 minutes if no improvement
39
Q

How would you treat anaphylaxis once specialist help has arrived?

A

- Constantly monitor pulse, sats, bp and ECG

- Establish airway

- IV fluid challenge with 500ml 0.9% saline in 5-10 minutes if normotensive, 1000ml if hypotensive

  • Chlorphenamine

- Hydrocortisone

  • If still breathing difficulty give IV or inhaled bronchodilators etc
40
Q

A

- Adult or child>12: 0.5mg (500ug) IM

- Child 6-12 years or small>12: 0.3mg (300ug) IM

- Child <6: 0.15mg (150ug)

41
Q
