A nurse is preparing to administer oral potassium to a client who has a potassium level of 5.5 mEq/L. Which of the following actions should the nurse take first?

Withhold the medication.

Administer a hypertonic solution.

Repeat the potassium level.

Monitor for paresthesia.

Answer and Explanation

The Correct Answer is C

Before administering any medication, the nurse should confirm the potassium level to ensure that it is still elevated and needs to be treated. Potassium levels can ﬂuctuate, so repeating the test will ensure that the client receives the appropriate treatment.

Options (a) Withhold the medication and (b) Administering a hypertonic solution may be appropriate interventions depending on the client's condition, but confirming the potassium level is the first step.

Option (d) Monitoring for paresthesia is important but not the first action that the nurse should take.
