A nurse is preparing to administer sertraline 0.05 g PO to a school-age child who has obsessive-compulsive disorder. Available is sertraline oral solution20 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2.5"]
Step 1: Convert the dose from grams to milligrams. We know that 1 gram = 1000 milligrams. So, 0.05 grams = 0.05 × 1000 = 50 milligrams.
Step 2: Calculate the volume of the solution to administer. The formula is Dose (mg) ÷ Concentration (mg/mL) = Volume (mL). So, 50 mg ÷ 20 mg/mL = 2.5 mL.
The nurse should administer 2.5 mL of sertraline oral solution.

Correct Answer is ["3.1"]
Explanation
Given:
- Total perphenazine to be administered: 200 mg
- The medication is to be divided into four equal doses
- Available perphenazine oral solution: 16 mg/mL
Step 1: Calculate the amount of perphenazine per dose
200 mg ÷ 4 = 50 mg/dose
Step 2: Calculate the volume of the oral solution per dose
(50 mg/dose) ÷ (16 mg/mL) = 3.125 mL/dose
Rounding to the nearest tenth, the nurse should administer 3.1 mL
Correct Answer is ["2.3"]
Explanation
Step 1: The dose to be administered is300 mg of phenobarbital sodium.
Step 2: The available phenobarbital sodium injection has a concentration of130 mg/mL. This means that for every 1 mL of the solution, there are 130 mg of phenobarbital sodium.
Step 3: To find out how many mL should be administered, we divide the dose by the concentration. So, 300 mg ÷ 130 mg/mL = 2.307692307692308 mL.
Step 4: Round the answer to the nearest tenth. So, 2.307692307692308 mL rounds to2.3 mL.
The nurse should administer 2.3 mL of phenobarbital sodium injection.
