Cardio v2 Flashcards
A 33-year old patient is due to undergo surgery, the
patient requires venous thromboembolism prophylaxis
and is renally impaired.
Which of the following pharmacological options is the
preferred option for patients that are renally impaired?
A. Aspirin
B. Edoxaban
C. Heparin (unfractionated)
D. Rivaroxaban
E. Warfarin
Unfractionated Heparin (UFH) is preferred in patients with renal impairment because it does not rely on renal clearance, unlike low molecular weight heparins (LMWH) or direct oral anticoagulants (DOACs). UFH is metabolised by the liver and has a shorter half-life, making it safer and more manageable in patients with renal dysfunction.
A 47-year-old patient has recently started on a low
molecular weight heparin (LMWH) and starts to develop
bruising of the skin.
What is the likely cause of the bruising?
A. Hyperkalaemia
B. Hypokalaemia
C. Hypersensitivity
D. Thrombocytopenia
E. Lymphocytopenia
Thrombocytopenia
