I've just finished my 3rd C&L rotation. Most of my consult request were for AMS, Agitation, Capacity Evaluation, Depression, Suicide attempt by OD or Intoxication, Psych Clearance after Delivery etc.
The most challenging task is Capacity Evaluation. But If you have good understanding of the process to evaluate the capacity , it would be piece of Cake. Delirium is another tricky situation. You may find pt totally incoherent but the resident who called for consult might find the patient totally in good shape after your consult. So, try to get collateral history form Nurses from previous shift also. ICU delirium is most common, For PGY-1's please consult your seniors before calling Psych consults.
