A nurse is preparing to administer ferrous sulfate 120 mg PO two times each day with meals to a client who is at 12 weeks of gestation and has anemia. Available is ferrous sulfate syrup 90 mg/5 mL. How many ml. should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["6.7"]
The question is asking for the volume of ferrous sulfate syrup that the nurse should administer per dose. The desired dose is 120 mg and the available syrup has a concentration of 90 mg/5 mL.
Let’s calculate this step by step:
Step 1: Identify the desired dose, which is 120 mg.
Step 2: Identify the concentration of the available medication, which is 90 mg/5 mL.
Step 3: Set up the equation to solve for the volume (V) in mL. The equation is (Desired dose ÷ Concentration) × Volume of the concentration = V.
Step 4: Substitute the known values into the equation: (120 mg ÷ 90 mg) × 5 mL = V.
Step 5: Solve the equation: V = (1.33) × 5 mL = 6.67 mL.
So, the nurse should administer approximately 6.7 mL of the ferrous sulfate syrup per dose.

Rounded off to the nearest whole number; 188ml/hr
Correct Answer is ["10"]
Explanation
The question is asking for the amount of docusate sodium liquid the nurse should administer per dose. The prescription is for 200 mg/day in two equally divided doses, and the liquid form of the medication is 50 mg/5 mL.
Step 1 is to determine the amount of medication needed per dose. Since the total daily dose is 200 mg and it’s divided into two doses, each dose will be 200 mg ÷ 2 = 100 mg.
Step 2 is to convert this dose from mg to mL using the concentration of the liquid medication. The concentration is 50 mg/5 mL, which means that 1 mL contains 50 mg ÷ 5 = 10 mg of the medication.
Step 3 is to calculate the volume of the medication needed for a 100 mg dose. Since 1 mL contains 10 mg, we need 100 mg ÷ 10 mg/mL = 10 mL.
So, the nurse should administer 10 mL of docusate sodium liquid per dose.
