(208 cards)
Absent popliteal and ankle pulses but present femoral pulse.
- What investigations would you do?
- Where is the occlusion?
- Difference between graft occlusion and compartment syndrome?
- Ankle brachial pressure index. Colour duplex scan.
- Superficial femoral artery.
- still don’t know 🥴
26y/o has 30min seizure.
- What is the definition of status epilepticus?
- Immediate bed side test?
- A+E immediate medication
- Further medication
- If is it alcohol induced what’s the Rx?
- 4 other causes of a seizure?
- Continuous seizure activity lasting 5 minutes or more or repetitive seizures without regaining consciousness (3 in 1 hr).
- BM
- IV lorazepam, buccal midazolam.
- Phenytoin.
- Thiamine/Pabrinex.
- Meningitis, trauma, hepatic encephalopathy, hypoglycaemia, brain tumour
- Mx of Addisonian crisis?
2. How to avoid future ones?
- IV hydrocortisone
2. Sick day rule to increase steroids when ill. Ensure good adherence to medications. Good patient education.
- Signs of paediatric deterioration?
- 6 blood test for a paeds ?sepsis?
- Mx of paeds sepsis?
- Unrousable, altered mental state, chest indrawing, grunting, decrease skin turgor, prolonged CRT, TC <60pm, TP, PaO2 <90%, mottled skin, cyanotic, non-blanching rash.
- ABG, blood cultures, FBC, clotting, ESR/CRP, creatinine, U+E.
- Broad spec ABx e.g. tazosin/ceftriaxone. IV fluids Analgesia. Inform senior for support.
- RFx for oesophageal cancer
2. Mx
- smoking, male, GORD + Barrett’s oesophagus, alcohol
2. early disease = endoscopic resection later do oesophagectomy.
- S+S of SLE.
2. Name 3 SLE drugs and how they work
- Discoid rash, painless oral ulcers, photosensitive rash, arthritis/arthralgia, malar rash, seizures, psychosis, proteinuria, HTN, oedema, chest pain + SOB (pericarditis and serositis) pallor and jaundice (haemolytic anaemia). Weight loss, fever.
- Methotrexate = dihydrofolate reductase inhibitor.
Cyclophosphamide = prevent DNA replication (alkylating agent). Ibuprofen = inhibits COX-1 and COX2. Etanercept = Anti-TNF.
- Score for PE assessment?
- Components of this score?
- What to do if low risk?
- Signs of a PE?
- Assess 30 day prognosis of a PE?
- What to do when discharging a PE patient?
- Wells score for pulmonary embolism
- Clinical features suggest PE, Heart rate >100bpm, PE is likely ∆, immobilised for 3days or surgery in past month, Hx of a PE/DVT, haemoptysis, Hx of malignancy.
- D Dimer
- Tachycardia, tachypnoea, elevated JVP, low BP, cyanotic.
- PESI = pulmonary embolism severity index.
- Dunno 🤷♀️
What drug class is most likely to improve prognosis in left ventricular systolic dysfunction?
ACE inhibitor.
Cause of deterioration and weakness in pt treated for acute asthma attack?
Hypokalaemia. Steroids and beta-agonist lower potassium.
Nerve involved in lung Ca pt with wasting and weakness of small muscles in right hand?
T1 nerve root
Ix for SAH if CT normal
LP in 12hrs - Xanthochromia
Nerve damaged if ankle examination ankle dorsiflexion and eversion are weak but ankle inversion is normal. The right ankle jerk is normal. Sensation is intact.
Common perineal nerve.
Causative organism if NON-bloody diarrhoea, vomiting, abdo pain but resolves spontaneously with 24hrs.
S.aureus
Why do coeliacs get malabsorption?
Reduced surface area from villous atrophy.
Metabolic disturbances in DKA
Increased protein catabolism, increased lipolysis, increased glucogenolysis, increased gluconeogenesis. Increased lipolysis = ketone production.
ABG of compensatory DKA
Decreased pH, decreased PaCO2.
1st line DMT2 med
Metformin
Hypercalaemia, high creatinine, high ESR and complaining of back pain and weight loss?
Multiple myeloma.
Hx of tiredness, chest pain, arthralgia, miscarriages, poor renal function and abnormal FBC
SLE
What do the antibodies in Goodpasture’s attack
Glomerular basement membrane
Haemoptysis and haematuria.
Lung Ca and hyponatreamia cause?
Paraneoplastic ADH release causing increased collecting duct permeability.
Analgesia in nephrolithiasis
diclofenac
ABG and U+E if severe vomiting
Hypochloraemic alkalosis.
Newborn baby goes home to family with chickenpox, mum has detectable varicella antibodies. what action?
None. Protected by placentally-acquired maternal antibodies and is therefore not at risk of overwhelming chicken pox infection.
