question 15 (2.5 points)
a patient is prescribed to receive a continuous infusion of lr. which solution should be given?
5% dextrose
0.9% sodium chloride
lactated ringers solution
5% dextrose with lactated ringers solution
question 16 (2.5 points)
which volume and strength of a solution is created if 300 ml of ensure is added to 600 ml of water?
900 ml ½ strength
900 ml 1/3 strength
900 ml ⅓ strength

Explanation:

Question 15

LR is the abbreviation for Lactated Ringer's solution. So when a patient is prescribed a continuous infusion of LR, the solution to be given is Lactated Ringer's solution.

Step1: Calculate total volume

The volume of Ensure is 300 mL and the volume of water is 600 mL. To find the total volume, we add these two volumes together.
$Total\ volume = 300\ mL + 600\ mL = 900\ mL$

Step2: Calculate the strength

The strength of a solution is calculated by the ratio of the volume of the solute (Ensure) to the total volume of the solution.
$Strength = \frac{Volume\ of\ Ensure}{Total\ volume} = \frac{300\ mL}{900\ mL} = \frac{1}{3}$

Answer:

C. Lactated Ringer's solution
