Secobarbital (Seconal) 150 mg is prescribed at bedtime for a male client who is scheduled for surgery in the morning. The scored tablets are labeled 0.1 gram/tablet. How many tablets should the nurse administer? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["2"]
First, let's convert grams to milligrams:
0.1 grams x 1000 mg/gram = 100 mg
Then, set up a proportion:
x tablets / 150 mg = 1 tablet / 100 mg
Cross-multiply:
100x = 150
Solve for x:
x = 150 / 100
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 secobarbital.

Explanation
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 ["2"]
Explanation
To calculate the number of additional tablets needed, we'll first determine the total number of tablets required for the new dose of 20 mg.
Step 1: Calculate the total number of tablets needed for the new dose:
Total Tablets = Desired Dose (mg) / Tablet Strength (mg)
Total Tablets = 20 mg / 5 mg/tablet
Total Tablets = 4 tablets
Step 2: Determine the number of tablets already administered:
The nurse administered 10 mg, which is equivalent to 2 tablets (since each tablet is 5 mg).
Step 3: Calculate the number of additional tablets needed:
Additional Tablets = Total Tablets - Tablets Already Administered
Additional Tablets = 4 tablets - 2 tablets
Additional Tablets = 2 tablets
Therefore, the nurse should administer 2 additional tablets of benazapril to reach the new prescribed dose of 20 mg.
