A client is taking furosemide (Lasix), a diuretic. and becomes confused. Which potassium level does the nurse correlate with this condition?
5.0 mEq/L
2.9 mEq/L
3.8 mEq/L
6.0 mEq/L
The Correct Answer is B
Furosemide is a loop diuretic that works by blocking the reabsorption of sodium and chloride in the ascending loop of Henle in the kidney, leading to increased urine output. However, this medication can also cause potassium loss through increased urinary excretion, which can lead to hypokalemia (low potassium level). Hypokalemia can cause confusion, weakness, and other neurological symptoms.
The normal range for serum potassium is 3.5 to 5.0 mEq/L. A potassium level of 2.9 mEq/L is below the normal range and is considered hypokalemic. Therefore, the nurse should correlate the client's confusion with the low potassium level and notify the healthcare provider to adjust the medication or provide potassium supplements if indicated.

Correct Answer is D
Explanation
One of the hallmarks of adrenal insufficiency is dehydration and decreased urinary output, which can lead to electrolyte imbalances such as hyperkalemia and hyponatremia. As treatment begins to take effect, the patient's fluid and electrolyte balance should improve, leading to an increase in urinary output. Acute adrenal insufficiency, also known as the Addisonian crisis, is a life-threatening condition caused by a sudden decrease in cortisol and aldosterone hormones. Treatment usually involves the administration of intravenous glucocorticoids and mineralocorticoids to replace the deficient hormones.
Decreasing serum sodium (a) and decreasing blood glucose (b) are not signs of improvement but rather indicative of continued adrenal insufficiency. Decreasing serum potassium (c) is also not a sign of improvement as it could indicate that the patient is developing hyperkalemia, which is a potential complication of adrenal crisis.
Correct Answer is B
Explanation
Diabetes insipidus is a condition where the body is not able to regulate water balance properly, leading to excessive urine output and dehydration. The patient's urine output of 800 ml/hr (option A) and low urine specific gravity of 1.003 (option C) is consistent with diabetes insipidus and requires monitoring, but they are not as immediately concerning as the patient's confusion and lethargy.
Confusion and lethargy may indicate severe dehydration, electrolyte imbalances, or even brain swelling (if the patient had a recent head injury, as mentioned in option D). These symptoms require immediate attention to prevent further complications and ensure the patient's safety.
