the nurse is preparing a tube feeding of ensure 280 ml (50% solution). full strength ensure is available in a 240 ml can. the nurse should use how many ml of ensure to prepare the feeding? (enter numeric value for only. if rounding is required, round to nearest whole number.)
Answer
# Explanation:
## Step1: Set up proportion
Let $x$ be the volume of full - strength Ensure. The concentration of full - strength Ensure is 100% or 1, and the final volume is 280 ml with a concentration of 50% or 0.5. Using the formula $C_1V_1 = C_2V_2$, we have $1\times x=0.5\times280$.
## Step2: Solve for $x$
$x = 0.5\times280=140$.
# Answer:
140
