For a patient prescribed Sodium polystyrene sulfonate for hyperkalemia, how many mL should the nurse administer if the dosage is 15 g and the suspension concentration is 1.25 g/5 mL?

For a patient prescribed Sodium polystyrene sulfonate for hyperkalemia, how many mL should the nurse administer if the dosage is 15 g and the suspension concentration is 1.25 g/5 mL?

• A. 30 mL
• B. 45 mL
• C. 60 mL
• D. 75 mL

Answer: (C)

To determine the volume of suspension to administer for a dosage of 15 g of Sodium polystyrene sulfonate, you can use the provided concentration of the suspension, which is 1.25 g per 5 mL. First, calculate how many grams are in each mL of the suspension by dividing the grams by the total volume: - 1.25 g / 5 mL = 0.25 g/mL. Next, since the prescribed dosage is 15 g, you can calculate the total volume needed by dividing the dosage by the concentration per mL: - 15 g / 0.25 g/mL = 60 mL. This calculation shows that to achieve the desired 15 g dosage, you need to administer 60 mL of the Sodium polystyrene sulfonate suspension. This matches the reasoning and confirms that the correct answer is the volume of 60 mL.

Next, since the prescribed dosage is 15 g, you can calculate the total volume needed by dividing the dosage by the concentration per mL:

• 15 g / 0.25 g/mL = 60 mL.
