Q

If no asthma signs and ipratropium not working what to do

A

Stop the SAMA (ipratropium)

Start LAMA and LABA so tiotropium and formoterol

LAMA and SAMA work on the same receptors

Also add salbutamol ?

When the kidneys are no longer sensitive to ADH meaning they have no ability to concentrate urine (polydipsia etc)

Do water deprivation test:
Urine osmalality after fluid deprivation is still low
Urine osmalality after desmopressin (synthetic ADH) is still low!

53

A

Hyperkalaemic metabolic acidosis

Addisons-> less aldosterone production-> more K+ in the blood. K+ is equivalent to H+ so it is acidic and so causes an acidosis

A

Staph. Aureus

Staph. Epidermidis if <2months post valve-surgery

67
Q

What is fonaparinux’s role in NSTEMI management

A

They are an anticoagulant - it is a LMWH

Used long-term for those who have had an NSTEMI to prevent future clots and has less bleeding risk than other LMWHs

Used in those who aren’t going straight for PCI

68
Q

How does NSTEMI drug management change if they are undergoing PCI or not

A

For antiplatelet therapy: still give initial aspirin loading dose AND another antiplatelet (either ticagrelor or prasugrel)

Still anticoagulate but in PCI you might give fondaparinux and unfracitonated heparin

Rest of management is the same?

69
Q

How does NSTEMI management change if they are high bleeding risk

A

Still give aspirin plus another antiplatelet therapy BUT in high bleeding risk give clopidogrel instead of ticagrelor or prasugrel

Nothing else changes apart from that you might stop DAPT earlier e.g. 3-6 months instead of 12

70
Q

How does the management of aortic dissection differ based on the type

A

If it is Stanford type A (ascending aorta) then do surgery while controlling BP to 100-120

Type B (descending aorta, distal to left subclavian origin, 1/3 of cases) = conservative Mx with IV labetalol and bed rest

You do a CT angiography to diagnose and classify- look for a false lumen

But loop diuretics also excrete calcium whereas thiazide diuretics retain calcium !

87
Q

Which cardiac problem predisposes you to mesenteric ischaemia

A

AF

Clot formation in left atrium goes to superior mesenteric artery causing ischaemia of the meentery

Causes severe abdominal pain

NEVER!

Only joking

If GRACE score is above 3.% then offer it!

A

Statins !

Can increase the risk of hepatotoxcitiy and rhabdomyolysis

96
Q

What is the mechanism for why nephrotic syndrome makes you in a hypercoagulable state

A

Loss of antithrombin III and plasminogen

Often high urate and LDH

111
Q

How to differentiate between aplastic and sequestration crises of sickle cell anaemia

A

Aplastic is caused by parvovirus infection. Sudden fall in Hb and low reticulocytes due to bone marrow suppression

Sequestration is pooling of blood due to sickling within organs. Associated with increased reticulocyte count

112

A

Hydroxyurea

This increases the foetal haemoglobin levels so reduces the amount of sickling (?)

So prevents crises

A

Resistance to action of protein C

Protein C controls the coagulation systems and so a lack thereof leads to more coagulation
