Correct Answer is ["0.6"]
Explanation
60mg=0.6
55mg= 55*0.6/60
Volume (mL) = 0.55 mL
Rounding to the nearest tenth, the nurse should administer 0.6 mL of enoxaparin solution to the client.
Correct Answer is ["6.7"]
Explanation
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.
