A nurse is collecting data from a client who has heart failure prior to the administration of furosemide. For which of the following findings should the nurse withhold the medication?

Blood pressure of 80/40 mm/Hg

Oxygen saturation of 95%

Serum sodium level of 140 mEq/L

Serum potassium level of 4.8 mEq/L

Answer and Explanation

The Correct Answer is A

A. A blood pressure of 80/40 mm/Hg indicates hypotension, which is a contraindication for administering furosemide. The medication can further lower blood pressure and increase the risk of adverse effects.
B. An oxygen saturation of 95% is within normal limits and does not indicate a need to withhold furosemide.
C. A serum sodium level of 140 mEq/L is normal and would not warrant withholding the medication.
D. A serum potassium level of 4.8 mEq/L is also normal and safe for furosemide administration, as the medication may cause potassium loss but does not require withholding if the level is within range.
