"How many tablets should the nurse administer in each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
Answer
The nurse should administer 2 tablets in each dose
Step-by-Step Calculation
Understanding the Problem
Total daily amitriptyline dose: 300 mg
Divided into 2 equal doses (every 12 hours)
Available amitriptyline tablets: 75 mg each
We need to find the number of tablets per dose.
Calculations
Calculate the dose per administration:
Dose per administration = Total daily dose / Number of doses
Dose per administration = 300 mg / 2 = 150 mg
Calculate the number of tablets per dose:
Tablets per dose = Dose per administration / Tablet strength
Tablets per dose = 150 mg / 75 mg/tablet = 2 tablets
The nurse should administer 2 tablets in each dose

Correct Answer is ["0.5"]
Explanation
The nurse should administer 0.5 ml of ziprasidone injection.
Step-by-Step Calculation
Understanding the Problem
We need to administer 10 mg of ziprasidone.
The available concentration is 20 mg/ml.
We need to find out how many milliliters (ml) to administer.
Setting up the Equation
We can use the formula:
Desired dose (mg) = Concentration (mg/ml) X Volume (ml)
Calculating the Volume
We know the desired dose (10 mg) and the concentration (20 mg/ml). We need to findthe volume.
Rearranging the formula to solve for volume, we get:
Volume (ml) = Desired dose (mg) / Concentration (mg/ml)
Substituting the values:
Volume (ml) = 10 mg / 20 mg/ml = 0.5 ml
The nurse should administer 0.5 ml of ziprasidone injection.
Correct Answer is ["1.5"]
Explanation
Answer
The nurse should administer 1.5 mL of haloperidol.
Step-by-Step Calculation
Understanding the Problem
Desired dose: 75 mg haloperidol
Available concentration: 50 mg/mL
We need to find the volume to administer.
Calculations
Calculate the volume to administer:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
Volume = 75 mg / 50 mg/mL = 1.5 mL
The nurse should administer 1.5 mL of haloperidol.
