The client's laboratory results indicate that the serum potassium level is 2.5 mEq/L (2.5 mmol/L). Which action should the nurse take?

Reference Range:

Potassium (K+) [3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)]

Prepare to administer a glucose, then insulin, then potassium infusion.

Instruct the client to increase daily intake of potassium rich foods.

Inform the healthcare provider of the need for potassium replacement.

Change the plan of care to include hourly urinary output measurements.

Answer and Explanation

The Correct Answer is C

A. The combination of glucose and insulin is used to shift potassium into cells, which would lower serum potassium levels further; this is not appropriate for treating hypokalemia.
B. Increasing dietary intake of potassium is important but not sufficient to correct a serum potassium level as low as 2.5 mEq/L, which requires more immediate intervention.
C. A potassium level of 2.5 mEq/L is critically low and can lead to life-threatening cardiac arrhythmias. The healthcare provider should be informed immediately to initiate potassium replacement therapy, likely via intravenous infusion.
D. Hourly urinary output measurements may be useful but are not the immediate priority in treating severe hypokalemia.

Correct Answer is B

Explanation

A. Administering an antianxiolytic might be premature and should only be done if prescribed and necessary.
B. Allowing the client to rest before taking vital signs helps ensure that the measurements are accurate and not influenced by recent emotional distress.
C. Notifying the client representative might be relevant later, but addressing the client's immediate needs and emotional state is the priority.
D. Offering hot tea may not be appropriate in this situation and does not directly address the need for accurate vital signs.

A. Remove the drainage bag and apply antibiotic ointment around the stoma. B. Apply a pulse oximeter to determine the client's oxygen saturation level. C. Replace the colostomy supplies with non-latex hypoallergenic supplies. D. Notify the healthcare provider of the appearance of the stoma immediately.

Correct Answer is D

Explanation

A. Applying antibiotic ointment is not appropriate for this situation as the issue is likely compromised blood flow, not infection.
B. Checking oxygen saturation is not related to the color change of the stoma.
C. Switching to non-latex supplies is important for clients with latex allergies but is not relevant to the immediate problem.
D. A dark red to bluish color of the stoma suggests compromised blood flow and possible ischemia, which requires immediate medical attention. The nurse should notify the healthcare provider immediately to address this potentially serious complication.
