A nurse is preparing to administer potassium chloride to a client who has a potassium level of 5.8 mEq/L. Which of the following actions should the nurse take?.
Inform the provider of the client's potassium level.
Hold the medication until the client has his evening meal.
Give the medication as prescribed.
Obtain a prescription to increase the dosage of the medication.
The Correct Answer is A
Choice A rationale:
The client’s potassium level is high (normal range is 3.6 to 5.2 mEq/L123), so the nurse should inform the provider before administering more potassium.
Choice B rationale:
Holding the medication until the client has his evening meal is not appropriate because the client’s potassium level is already high.
Choice C rationale:
Giving the medication as prescribed is not appropriate because the client’s potassium level is already high.
Choice D rationale:
Obtaining a prescription to increase the dosage of the medication is not appropriate because the client’s potassium level is already high.
