MCQs Revision Flashcards
What is the target INR in a patient with a mechanical heart valve?
3.5
What should we do to a patient with minor bleeding and an INR of 6.0?
Stop the warfarin and restart when the INR is less than 5.
What should we do to a patient with their first DVT and an INR of 2.5?
Nothing, continue warfarin with no change.
What should we do to a patient with AF, no bleeding and an INR of 8.0?
Stop the warfarin and restart when the INR is less than 5.
What should we do to a patient who has had a recurrent DVT while being treated with warfarin with an INR of 2.0?
Increase the warfarin dose, the target INR is 3.0 for them.
The efficacy of unfractionated heparin 20units/kg/hour intravenous infusion is routinely measured via what
APTT
Have beta blockers been shown to improve mortality, but not reduce hospitalisations in people with CHF?
NOOO
What antidepressants should be first line in patients with known suicidality?
SSRIS
TCAs can cause what side effects?
Heart block
Urinary retention
Constipation
TCAs have anticholinergic side effects
SSRIs are most commonly associated with what electrolyte disturbances?
Hyonatraemia
Why can SSRIs and TCAs increase the fall risk in the elderly?
Postural hypotension.
What treatment is essential in all patients with established cardiovascular disease?
Antiplatelet
Patients diagnosed with acute coronary syndrome should be offered higher intensity statins with what target level of non-LDL reduction?
No target.
Offer even if they have TC below 4, which is the NICE target.
When should BBs be started in a patient who is clinically stable post STEMI?
As soon as POSSIBLE.
They reduce myocardial oxygen demand, we can even give it to them via IV as it has been shown that the earlier they are started, the better outcomes.
What carries a higher risk of mortality at 6 months post event, STEMI or NSTEMI?
NSTEMI,
STEMI higher in short term but NSTEMI higher in longer term.
Which is the better option to limit the extension of coronary thrombosis in ACS?
LMWH or UFH?
LMWH are better.
Use Fondaparinux.
Why are UFH usually administered via a continuous IV infusion?
URH are rapid acting with a half-life of approximately 60 minutes.
Why is warfarin used in patients with AF (no other conditions)?
For thrombus (clot) prevention.
Patients diagnosed with TIA should be prescribed __________ 75mg om for primary prevention of ischemic stroke.
Clopidogrel
Atelpase is recommended for the treatment of what?
Stroke if within 4.5 hours.
Would we recommend anticoagulants as an alternative to antiplatelet drugs in acute ischaemic stroke patients who are in sinus rhythm?
NOOOOOO
NOOOO
NO
