Dosage Calculation RN Maternal Newborn Proctored Assessment 3.1 ( 37 Questions)
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 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.
