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.

Correct Answer is ["125"]
Explanation
To calculate the infusion rate, we'll use the following formula:
Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)
Plugging in the given values:
Infusion Rate = 1000 mL / 8 hours
Calculating the result:
Infusion Rate = 125 mL/hour
Therefore, the nurse should program the infusion pump to deliver 125 mL/hour.
Correct Answer is ["2"]
Explanation
To determine the number of tablets needed, we can set up a proportion:
x tablets / 0.6 mg = 1 tablet / 0.4 mg
Cross-multiplying:
0.4x = 0.6
Solving for x:
x = 0.6 / 0.4
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 nitroglycerin 0.4 mg sublingually if the client experiences chest pain
