A nurse is preparing to administer atenolol 50 mg PO every 12 hr. The amount available is atenolol 25 mg/tab. How many tablets should the nurse administer per dose? Round off to the nearest tenths place. Enter numeric value only (numbers and decimal points only, no commas or labels)
The Correct Answer is ["2"]
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 ["2"]
Explanation
Identify the information given:
Prescribed dose: 2 grams of amoxicillin per day, divided into two doses.
Available concentration: 500 mg tablets
Determine the dose per administration:
Since the daily dose is divided into two doses, each dose will be: 2 g/day ÷ 2 doses/day = 1 g/dose
Determine the number of tablets per dose:
Find how many 500 mg tablets are needed to make 1 g (or 1000 mg) of amoxicillin.
Set up a proportion to solve for the unknown number of tablets (X):
500 mg/tablet = 1000 mg/X tablets
Cross-multiplying gives us:
500 mg x X tablets = 1000 mg x 1 tablet
Simplifying:
500X = 1000
Solving for X:
X = 1000 / 500 = 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
