(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.5"]
-Step 1: Define the amount of diazepam to be administered and the concentration of the available diazepam injection. We know that the diazepam dose is 7.5 mg and the diazepam concentration is 5 mg/mL.
-Step 2: Calculate the volume of diazepam injection to be administered. The calculation is 7.5 mg (diazepam dose) ÷ 5 mg/mL (diazepam concentration) = 1.5 mL.

Correct Answer is ["3.5"]
Explanation
Step 1: Convert the dose from grams to milligrams. We know that 1 gram = 1000 milligrams. So, 0.7 grams = 0.7 × 1000 = 700 milligrams.
Step 2: The total daily dose is divided equally into two doses, so each dose is half of the total daily dose. So, 700 mg ÷ 2 = 350 mg per dose.
Step 3: The available quetiapine tablets have a concentration of 100 mg/tablet. This means that for every 1 tablet, there are 100 mg of quetiapine.
Step 4: To find out how many tablets should be administered per dose, we divide the dose by the concentration. So, 350 mg ÷ 100 mg/tablet = 3.5 tablets.
Step 5: Round the answer to the nearest tenth. So, 3.5 tablets rounds to3.5 tablets.
The nurse should administer3.5 tablets of quetiapine in each dose.
