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
Although increasing fluid intake and fiber intake are important interventions for preventing constipation, it is important to first assess the patient's current situation and risk factors for constipation. Additionally, while a daily bowel movement is not necessary for everyone, it is important to understand the patient's usual bowel habits and whether or not their current regimen is effective for them. Therefore, the nurse should perform a focused nursing assessment to identify the patient's risk factors for constipation and evaluate their current bowel regimen before providing specific interventions or recommendations.
