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.
Change the plan of care to include hourly urinary output measurements.
The Correct Answer is C
Rationale:
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 C
Explanation
Rationale:
A. Examining feet daily is important for preventing foot complications, such as ulcers, in diabetics but is not directly related to preventing retinopathy and nephropathy.
B. Wearing compression stockings is not specifically recommended for preventing retinopathy or nephropathy in diabetes.
C. Maintaining stable blood glucose levels is crucial for preventing or slowing the progression of diabetic complications such as retinopathy and nephropathy. Good glycemic control minimizes the damage to blood vessels in the eyes and kidneys.
D. While regular eye exams are important for detecting retinopathy early, maintaining stable blood glucose levels is key to preventing the development of complications in the first place.
Correct Answer is B
Explanation
Rationale:
A. Insulin glargine is a long-acting insulin, and its dose is not based on before-meal blood sugar readings.
B. The client needs to be taught how to self-administer insulin glargine, as it is given subcutaneously once daily, usually at the same time each day.
C. Increasing the dosage in response to ketoacidosis is inappropriate; emergency treatment is required for this condition.
D. Insulin glargine does not have a role in treating severe hypoglycemia; fast-acting glucose or glucagon is used for such situations.
