The nurse is preparing to administer IV furosemide (Lasix) to a client with hypertension. What is the most important finding to report to the health care provider?
A.
Blood glucose level of 175 mg/dl.
B.
Orthostatic systolic BP decrease of 12 mm Hg
C.
Serum potassium level of 3.0 mEq
D.
Current blood pressure (BP) reading of 166/94 mm Hg
The correct answer and Explanation is :
The correct answer is C. Serum potassium level of 3.0 mEq.
Explanation:
Furosemide (Lasix) is a loop diuretic commonly used to treat conditions like hypertension and fluid overload. One of the critical side effects of furosemide is its potential to cause hypokalemia, which is a condition characterized by low potassium levels in the blood. Normal serum potassium levels typically range from 3.5 to 5.0 mEq/L. A potassium level of 3.0 mEq/L is significantly low and poses a risk for serious complications, including arrhythmias, muscle weakness, and increased risk of digitalis toxicity if the patient is on digoxin.
Other Findings:
- A. Blood glucose level of 175 mg/dl: While hyperglycemia may warrant attention, it is not an immediate concern related to furosemide administration and does not directly threaten the patient’s immediate safety.
- B. Orthostatic systolic BP decrease of 12 mm Hg: This finding may suggest some volume depletion or the effects of the medication but is not as critical as the potassium level. An orthostatic change might be monitored but does not necessitate immediate intervention.
- D. Current blood pressure (BP) reading of 166/94 mm Hg: This reading indicates hypertension but is expected in a patient receiving treatment. It is important to monitor, but again, it is not as urgent as the low potassium level.
In summary, while all these findings are relevant to the patient’s overall condition, the serum potassium level of 3.0 mEq is the most pressing concern that should be reported to the healthcare provider before administering IV furosemide, as it directly impacts the patient’s safety and response to the medication.
