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?
A.
Oxygen saturation of 95%.
B.
Serum sodium level of 140 mEq/L.
C.
Blood pressure of 80/40 mm Hg.
D.
Serum potassium level of 4.8 mEq/L.
The Correct Answer and Explanation is:
The correct answer is C. Blood pressure of 80/40 mm Hg.
Explanation:
Furosemide, a loop diuretic, is commonly used in the management of heart failure to reduce fluid overload by promoting diuresis. However, it is essential to carefully monitor certain parameters before administering this medication, as its effects can significantly impact fluid and electrolyte balance.
- Oxygen Saturation of 95%: This value indicates that the client has adequate oxygenation and is not an immediate concern for withholding furosemide. While oxygen saturation is an essential parameter to monitor in heart failure patients, it is not a direct indicator for withholding furosemide.
- Serum Sodium Level of 140 mEq/L: A serum sodium level of 140 mEq/L is within the normal range (135-145 mEq/L). Normal sodium levels suggest that there is no significant sodium imbalance that would necessitate withholding furosemide. However, electrolyte levels should be monitored regularly to prevent complications related to diuretic therapy.
- Blood Pressure of 80/40 mm Hg: A blood pressure of 80/40 mm Hg is indicative of hypotension. Furosemide can cause a further decrease in blood pressure due to its diuretic effect, which can exacerbate hypotension. In patients with already low blood pressure, administering furosemide could lead to an unsafe drop in blood pressure, potentially resulting in dizziness, fainting, or worsening of cardiovascular instability. Therefore, it is crucial to assess the client’s blood pressure before administration, and in cases of hypotension, furosemide should generally be withheld until blood pressure is stabilized.
- Serum Potassium Level of 4.8 mEq/L: A serum potassium level of 4.8 mEq/L is within the normal range (3.5-5.0 mEq/L). Normal potassium levels indicate that there is no immediate risk of hypokalemia, which is a common concern with diuretic use. However, regular monitoring of potassium levels is necessary, as furosemide can lead to hypokalemia.
In summary, a blood pressure of 80/40 mm Hg is a critical finding that warrants withholding furosemide and assessing the client’s overall condition to prevent potential complications related to low blood pressure.
