A nurse is preparing to administer morphine 18 mg via IV bolus to a client. The amount available is morphine 10 mg/mL. How many mL should the nurs administer per dose? Round to the nearest tenths place. Enter numeric value only (numbers and decimal points only, no commas or labels)
The Correct Answer is ["1.8"]
Identify the given information:
Prescribed dose: 18 mg of morphine
Available concentration: 10 mg/mL
Determine the volume to be administered:
We can set up a proportion to solve for the unknown volume (X):
10 mg/mL = 18 mg/X mL
Cross-multiplying gives us:
10 mg x X mL = 18 mg x 1 mL
Simplifying:
10X = 18
Solving for X:
X = 18 / 10 = 1.8 mL

Correct Answer is ["2"]
Explanation
Identify the given information:
Prescribed dose: 50 mg of atenolol per dose
Available tablets: 25 mg tablets
Determine the number of tablets per dose:
Find how many 25 mg tablets are needed to make 50 mg of atenolol.
Set up a proportion to solve for the unknown number of tablets (X):
25 mg/tablet = 50 mg/X tablets
Cross-multiplying gives us:
25 mg x X tablets = 50 mg x 1 tablet
Simplifying:
25X = 50
Solving for X:
X = 50 / 25 = 2 tablets
Correct Answer is ["1.5"]
Explanation
Identify the information given:
Prescribed dose: 15 mg of haloperidol
Available concentration: 10 mg/mL
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
10 mg/mL = 15 mg/X mL
Cross-multiplying gives us:
10 mg x X mL = 15 mg x 1 mL
Simplifying:
10X = 15
Solving for X:
X = 15 / 10 = 1.5 mL
