7. Before administering furosemide (Lasix), a nurse should verify that:
. The blood pressure is under 180/90 mm Hg.
. The potassium is over 4 mg/dL.
. There are no crackles in the lungs.
. The client has an indwelling catheter in place.
Test-Taking Tip
Only one of the options relates to the importance of the potassium level. The other options relate to assessing and managing the impact of fluid in the client.

Answer 1 is incorrect because high blood pressure (e.g., 180/90) is treated with diuretics and does not need to be verified (although furosemide is not usually the first choice). Answer 2 is correct because this diuretic will cause potassium to be lost in the urine. Clients receiving furosemide often need K+ replacement. Answer 3 is incorrect because crackles that are present with pulmonary edema may be treated with furosemide. Answer 4 is incorrect because, although the urine volume will be increased, there is no need for a bladder catheter if the client can void.
