FAILURE: These are the quick recall potential etiologies of congestive heart failure exacerbations. If you can sit with the discomfort of the silence until you’re able to answer the questions, you will know that you can easily and quickly recall this knowledge comfortably in the moment you need it. Then, ask yourself: do I need to check a thyroid function? Is this patient non-compliant with medications and do I need to ask the patient if they recently took their meds?

Do I need to consider the pulmonary embolism risk factors mnemonic THROMBOSIS?
