A nurse is preparing to administer lorazepam 2 mg PO. Available is lorazepam 1 mg tablets.
How many tablets should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Full Explanation
Step 1 is to determine the amount of lorazepam needed, which is 2 mg as prescribed.
Step 2 is to calculate the number of tablets required. Since each tablet contains 1 mg, we divide the prescribed dose by the strength per tablet:
2 mg ÷ 1 mg per tablet = 2 tablets

A nurse is preparing to administer amantadine 150 mg PO for a client who is experiencing parkinsonism due to an antipsychotic medication.
Available is amantadine 50 mg/5 mL oral solution.
How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Full Explanation
Step 1 is to determine the amount of amantadine needed, which is 150 mg as prescribed.
Step 2 is to calculate the volume of the solution needed to deliver this dose. The available solution has a concentration of 50 mg per 5 mL. Using the formula:
(Prescribed dose ÷ Available dose) × Volume per dose
(150mg ÷ 50mg) × 5mL = 15mL
Therefore, the correct answer is 15 mL.
