A nurse is planning to administer lithium 8 g PO daily to a client. How many my should the nurse administer? (Round the answer to the nearest whole number. Use : leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1800"]
Identify the Given Dose:
The prescribed dose is 1.8 grams (g).
Convert Grams to Milligrams:
We need to convert grams (g) to milligrams (mg) because medication dosages are often expressed in milligrams.
There are 1000 milligrams in 1 gram (1 g = 1000 mg).
1.8 g x 1000 mg/g = 1800 mg

Correct Answer is ["0.9"]
Explanation
Identify the Desired Dose and Available Concentration:
Desired Dose: 17.5 mg of ziprasidone
Available Concentration: 20 mg/mL (This means there are 20 mg of ziprasidone in every 1 mL of solution)
Set up the Calculation:
We need to find the volume (in mL) that contains the desired dose of 17.5 mg.
We can use the following formula:
Volume (mL) = Desired Dose (mg) / Available Concentration (mg/mL)
Plug in the Values and Calculate:
Volume (mL) = 17.5 mg / 20 mg/mL
Volume (mL) = 0.875 mL
Round to the Nearest Tenth:
0.9 mL
Correct Answer is ["0.5"]
Explanation
Identify the Desired Dose and Available Concentration:
Desired Dose: 75 mg of amitriptyline
Available Concentration: 150 mg per tablet
Set up the Calculation:
We need to find out how many tablets contain the desired dose of 75 mg.
We can use the following formula:
Number of Tablets = Desired Dose (mg) / Available Dose per Tablet (mg)
Plug in the Values and Calculate:
Number of Tablets = 75 mg / 150 mg/tablet
Number of Tablets = 0.5 tablets
Round to the Nearest Tenth :
0.5 tablets
