A nurse is caring for a client who has an extracellular fluid volume deficit. Which of the following findings should the nurse expect?
A.
Distended neck veins
B.
Postural hypotension
C.
Dependent edema
D.
Bradycardia
The correct answer and Explanation is :
The correct answer is B. Postural hypotension.
Explanation:
Extracellular fluid (ECF) volume deficit, also known as hypovolemia, occurs when there is a decrease in the total amount of extracellular fluid in the body. This condition can result from various factors, including dehydration, excessive fluid loss through vomiting, diarrhea, or sweating, or inadequate fluid intake.
Key Findings in ECF Volume Deficit:
- Postural Hypotension:
- This is a common finding in ECF volume deficit. When a person with low extracellular fluid volume stands up or changes position quickly, their blood pressure may drop, leading to dizziness or lightheadedness. This occurs because the reduced fluid volume results in decreased blood volume, which impairs the body’s ability to maintain blood pressure when shifting positions.
- Distended Neck Veins:
- Distended neck veins are more typically associated with fluid overload or conditions that increase venous pressure, such as heart failure. In the case of ECF volume deficit, neck veins are usually not distended; they might even appear flat or collapsed due to the low blood volume.
- Dependent Edema:
- Dependent edema refers to swelling that occurs in the lower parts of the body, such as the legs, due to fluid accumulation. This is generally associated with fluid overload or venous insufficiency rather than a fluid deficit.
- Bradycardia:
- Bradycardia, or a slow heart rate, is not a typical finding in ECF volume deficit. In fact, hypovolemia often causes tachycardia (an increased heart rate) as the body compensates for the reduced blood volume by increasing heart rate to maintain adequate circulation and perfusion.
In summary, the most indicative finding of an extracellular fluid volume deficit is postural hypotension, as the body struggles to maintain adequate blood pressure with reduced fluid levels.
