A nurse is preparing to administer potassium chloride (KCL). The provider prescribes potassium chloride (KCL) 20 mEq suspension PO daily. The bottle is labeled KCL elixir, 10 mEq/mL. Which of the following should the nurse administer?
2 mL.
2.5 mL.
1.5 mL.
1 mL.
The Correct Answer is A
Choice A rationale:
The provider prescribes 20 mEq of KCL. The bottle is labeled as 10 mEq/mL. Therefore, to administer 20 mEq, the nurse should give 2 mL (20 mEq ÷ 10 mEq/mL = 2 mL).
Choice B rationale:
Administering 2.5 mL would give 25 mEq of KCL, which is more than the prescribed dose.
Choice C rationale:
Administering 1.5 mL would give 15 mEq of KCL, which is less than the prescribed dose.
Choice D rationale:
Administering 1 mL would give 10 mEq of KCL, which is half the prescribed dose.
