    i couldn't really answer the poll itself, I base it individually on each resident. Heavier residents more towards a 90 and for a smaller resident the traditional 45.

    depends what the medication is.
    some allergy shots are better tolerated @ 90
    some vaccinations must be @ 45
    Personally, I like 90.

    For obese patients 90 and for others 45 and even less if skin layer is very thin.

    Depends on size of needle involved. 1/2 inch or less, 90 degrees, greater than 1/2 inch, 45 degrees. Also, amount of pt SQ tissue also factors into this.

    Used 45 degrees for a hundred years...until enoxaparin came along(LMWH).Our policy says 90 degrees for it.

    I was taught 90' all the time-scrunch up the flesh on the skinny ones, only give with a 28 gauge, don't use over a 1/2" needle unless they are chubby then use a 5/8, if very chubby 'dimple' a little with it.
