A client with multiple sclerosis and muscle spasms receives a prescription for baclofen (Kemstro) 30 mg PO daily. The medication is supplied from the pharmacy in 20 mg scored tablets. How many tablets should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["2"]
To calculate the number of tablets needed, we can set up a proportion:
x tablets / 30 mg = 1 tablet / 20 mg
Cross-multiplying:
20x = 30
Solving for x:
x = 30 / 20
x = 1.5
Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.
Therefore, the nurse should administer 2 tablets of baclofen.

Correct Answer is ["22"]
Explanation
Calculating the Propofol Infusion Rate
Step 1: Convert weight to kilograms:
198 lbs x (1 kg / 2.20462 lbs) ≈ 90 kg
Step 2: Calculate the desired dose rate in mcg/minute:
8 mcg/kg/minute x 90 kg = 720 mcg/minute
Step 3: Calculate the concentration of propofol in the IV solution:
100 mg/50 mL = 2 mg/mL
Step 4: Calculate the infusion rate in mL/hour:
First, convert mcg to mg:
720 mcg x (1 mg / 1000 mcg) = 0.72 mg/minute
Then, set up a proportion:
x mL/hour / 0.72 mg/minute = 60 minutes/hour / 2 mg/mL
Cross-multiply and solve for x:
x mL/hour = 0.72 mg/minute x 60 minutes/hour / 2 mg/mL
x mL/hour ≈ 21.6 mL/hour
Therefore, the nurse should program the infusion pump to deliver approximately 22 mL/hour.
Correct Answer is C
Explanation
To determine the number of tablets needed, we can set up a proportion:
x tablets / 7.5 mg = 1 tablet / 5 mg
Cross-multiplying:
5x = 7.5
Solving for x:
x = 7.5 / 5
x = 1.5
Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.
Therefore, the nurse should administer 2 tablets of metolazone.
