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 A
Explanation
The nurse will include the instruction "Offer the client the commode or urinal every 2 hours" in the teaching plan for the client's family. This approach is known as timed voiding and can help the client re-establish a regular pattern of urination. Option "a" promotes frequent voiding, which helps
prevent accidents and promotes bladder health. Option "b" is not a recommended approach and can lead to dehydration, urinary tract infections, and other complications. Option "c" is also not recommended since holding urine for extended periods can lead to bladder distention and increase the risk of urinary tract infections. Option "d" is also not recommended since catheterization should only be considered in specific cases where other options have failed or are not feasible.
Correct Answer is C
Explanation
The nurse should act on the order to insert a 16 French retention catheter first. The patient's markedly distended bladder and agitated and confused state suggest acute urinary retention, which can be relieved by inserting a catheter to drain the urine. This is a priority intervention as urinary retention can lead to serious complications such as bladder rupture, hydronephrosis, and renal failure. Once the catheter is inserted and the patient's bladder is drained, the healthcare provider can order further tests such as an IVP or blood tests to assess renal function. The order for lorazepam can be addressed after the catheter is inserted and the patient's urinary retention is addressed.
