A nurse is preparing to administer valproic acid 125 mg PO. Available is valproic acid syrup 250 mg/5 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"]
To determine how many mL of valproic acid syrup the nurse should administer, we need to use a ratio and proportion:
250 mg : 5 mL = 125 mg : x mL Cross-multiplying, we get:
250 mg x x mL = 5 mL x 125 mg Simplifying, we get:
x = (5 mL x 125 mg) / 250 mg x = 2.5 mL

Correct Answer is ["0.5"]
Explanation
To calculate the required teaspoons (tsp) of amoxicillin suspension per dose, we need to use the following
formula:
tsp = (dose in mg) ÷ (concentration in mg/mL) ÷ 5 mL per tsp Substituting the given values in the formula, we get:
tsp = (100 mg) ÷ (200 mg/5 mL) ÷ 5 mL per tsp
tsp = 0.5 tsp
Correct Answer is ["0.75"]
Explanation
The correct answer and explanation is:
0.75 mL.
To calculate the mL needed, divide the dose (60 mg) by the concentration (80 mg/mL): 60 mg ÷ 80 mg/mL = 0.75 mL
Therefore, the correct answer is 0.75 mL.
