The Correct Answer is ["2"]
Given:
Prescribed dose: 0.2 mg of desmopressin per dose
Available tablets: 0.1 mg tablets
Steps to solve:
Determine the number of tablets per dose:
Find how many 0.1 mg tablets are needed to make 0.2 mg of desmopressin.
Set up a proportion to solve for the unknown number of tablets (X):
0.1 mg/tablet = 0.2 mg/X tablets
Cross-multiplying gives us:
0.1 mg x X tablets = 0.2 mg x 1 tablet
Simplifying:
0.1X = 0.2
Solving for X:
X = 0.2 / 0.1 = 2 tablets

Steps to solve:
Determine the number of tablets per dose:
Find how many 50 mg tablets are needed to make 25 mg of atenolol.
Set up a proportion to solve for the unknown number of tablets (X):
50 mg/tablet = 25 mg/X tablets

50 mg x X tablets = 25 mg x 1 tablet
Simplifying:
50X = 25
Solving for X:
X = 25 / 50 = 0.5 tablets
Correct Answer is ["650"]
Explanation
Rationale: Step 1 is to convert the client's weight from pounds (lbs) to kilograms (kg) Client weight = 286 lbs Conversion factor = 2.2 lbs per 1 kg Weight in kg = (286 ÷ 2.2) 286 ÷ 2.2 = 130 Weight in kg = 130 kg
Step 2 is to calculate the total dose in milligrams (mg) per dose Prescribed dose = 5 mg/kg Total mg dose = 130 × 5 130 × 5 = 650 Total mg dose = 650 mg
Step 3 is to round to the nearest whole number 650 = 650 Answer: 650
