I'm sure Daytonite will be along with great advice, however I'd say as a rule to start with actual problems and ABCs, and I would rank as:
1. Herpes Zoster
(If your patient is contagious, and in severe neuralgic pain, this would be their biggest problem I would think).
2. Hypertension (actual physical problem present, which would be made worse by their HZ pain)
3. Hypothyroidism (needs treatment with throxine supplementation, actual problem as opposed to risk of problem)
4. Osteoarthritis (pain, immobility)
Keep in mind, I'm not an expert at care plans
, but after 10 years ICU experience, those are what I'd worry about, in order.
