- Determine the volume of water for dilution:
total volume of liquid −volume of drug =volume of water for dilution
Example: acetaminophen 650 mg, q6h, PRN for pain
Have (on hand): Acetaminophen elixir 65 mg/mL.
Average mOsm/kg = 5400
- D ×V = 650 mg ×1 mL = 10 mL
H 65 mg
H: V D:x
65 mg : 1mL :: 650 mg: :xmL
65x= 650
x=10 mL of acetaminophen
- known mOsm (5400) ×volume of drug (10) = 5400 × 10 =108 mL of
liquid desired mOsm (500) 500 - total volume of liquid (108 mL) ×volume of drug (10 mL0 =98 mL of
water for dilution
Nursing Process
Assessment
- Assess the tape around the nasogastric tube
- Assess sign and symptoms of intolerance to feedings
- Intake and output
- Bowel sounds
- Baseline laboratory values
Nursing Diagnoses
- Risk for fluid volume deficit
- Risk for diarrhea related to tube feedings
