A client receives a prescription for dextrose 5% in water 500 mL IV to be infused over 4 hours. The IV administration set delivers 15 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["31"]
To find out how many gtt/min the nurse should regulate the infusion;
We can use the following formula:
Flow rate (gtt/min) = Total volume (mL) / Time (min) × Drop factor (gtt/mL)
Given:
Total volume = 500 mL
Time = 4 hours = 240 minutes (since 1 hour = 60 minutes)
Drop factor = 15 gtt/mL
Substituting the given values into the formula:
Flow rate (gtt/min) =500 mL/240 min ×15 gtt/mL
After performing the calculation, we find that the flow rate equals 31.25 gtt/min.
So, the nurse should regulate the infusion to 31 gtt/min (rounded to the nearest whole number).

Correct Answer is C
Explanation
A) Serum ammonia level of 30 pg/dl (17.62 μmol /dL): Serum ammonia level is not directly affected by sodium polystyrene sulfonate administration. Ammonia levels are typically related to liver function and are not relevant in assessing the effectiveness of this medication for hyperkalemia.
B) Serum glucose level of 120 mg/dL (6.7 mmol/L): Serum glucose level is unrelated to the action of sodium polystyrene sulfonate. While hyperkalemia can sometimes lead to glucose metabolism abnormalities, the glucose level alone does not provide information about the medication's effectiveness.
C) Serum potassium level of 3.8 mEq/L (3.8 mmol/L): Sodium polystyrene sulfonate, also known as Kayexalate, is a medication used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium excretion through feces. A decrease in serum potassium level within the normal range indicates that the medication has been effective in lowering potassium levels, which is the intended therapeutic outcome in the context of treating hyperkalemia associated with acute kidney injury (AKI).
D) Hemoglobin level of 13.5 g/dL (135 g/L): Hemoglobin level is unrelated to the action of sodium polystyrene sulfonate. It reflects the oxygen-carrying capacity of red blood cells and is not directly influenced by potassium-lowering medications.
