A client is prescribed furosemide, a loop diuretic, for hypertension.
The nurse should instruct the client to monitor for which of the following signs of electrolyte imbalance (Select all that apply).
A.
Muscle cramps.
B.
Dry mouth.
C.
Numbness and tingling.
D.
Weakness and fatigue.
E.
Tachycardia.
The correct answer and Explanation is :
The correct answers for signs of electrolyte imbalance that a client taking furosemide should monitor for are:
A. Muscle cramps.
C. Numbness and tingling.
D. Weakness and fatigue.
E. Tachycardia.
Explanation:
Furosemide is a loop diuretic that promotes the excretion of sodium, chloride, and water through the kidneys. This process can lead to a significant loss of electrolytes, particularly potassium, magnesium, and calcium, resulting in various clinical manifestations.
A. Muscle cramps: Low potassium (hypokalemia) can lead to muscle cramps and spasms. This is a common side effect of loop diuretics like furosemide, as they can cause a substantial drop in potassium levels.
C. Numbness and tingling: Electrolyte imbalances, particularly involving calcium and potassium, can lead to neurological symptoms, including numbness and tingling in extremities. This occurs due to altered nerve conduction and muscle function.
D. Weakness and fatigue: Both hypokalemia and hypomagnesemia can cause generalized weakness and fatigue. These symptoms arise from the essential role these electrolytes play in muscle contraction and overall energy metabolism.
E. Tachycardia: Low potassium levels can lead to cardiac arrhythmias, including tachycardia. Monitoring heart rate is crucial, as electrolyte imbalances can affect cardiac function, leading to potential complications.
B. Dry mouth is less specific and not a direct indicator of electrolyte imbalance. While it can occur due to dehydration or medication side effects, it is not as closely associated with the effects of furosemide as the other options.
Overall, it is essential for clients on furosemide to monitor these symptoms and report any significant changes to their healthcare provider, as timely intervention can prevent severe complications related to electrolyte disturbances. Regular monitoring of electrolyte levels through blood tests is also a critical part of managing therapy with furosemide.
