|
|
Ca Blockers side effects
|
Safe
-hypotension, palpitations -tachy or brady, contipation, nas,vomit |
|
|
Nursing implications
|
VS, respiratory
-Wt gain 2lbs/day, or 5lbs/wk -pulse <60 report -No alcohol, spas, (cause fainting) |
|
|
Nursing implications for Nitro
|
Proper technique
-never chew or swallow -burning means the med is still potent (SL) -keep fresh supply(3 months) -Stored in airtight dark glass containerw/metal cap, no cotten. Topicals should be removed at night (Nitro free period) PRN dose at first hint of pain -IV Nitro in Glass container given with Pump -Discard blue green, and red solution |

|
|
