A nurse is planning to monitor a client for dehydration following several episodes of vomiting and an increase in the client’s temperature.
Which of the following findings should the nurse identify as an indication that the client is dehydrated?
A.
Distended neck veins
B.
Bounding pulse
C.
BP 146/94 mm Hg
D.
Urine specific gravity 1.034 .
The correct answer and Explanation is :
The correct answer is D. Urine specific gravity 1.034.
Explanation
Dehydration occurs when the body loses more fluids than it takes in, leading to an imbalance that affects various bodily functions. Monitoring for signs of dehydration is critical, especially in clients who have experienced significant fluid loss, such as from vomiting and fever.
Urine specific gravity is a key indicator of dehydration. It measures the concentration of solutes in the urine and reflects how well the kidneys are conserving or excreting water. A normal urine specific gravity ranges from 1.010 to 1.025. A value of 1.034, which is higher than the normal range, indicates concentrated urine and suggests that the client is likely dehydrated. This concentration occurs because the kidneys are conserving water in response to decreased fluid volume in the body.
In contrast, the other options are less indicative of dehydration:
- A. Distended neck veins: This is usually a sign of fluid overload or venous pressure increase, not dehydration. In dehydration, neck veins are more likely to appear flat or collapsed due to reduced blood volume.
- B. Bounding pulse: A bounding pulse typically suggests increased fluid volume or hypertension. In dehydration, a pulse may be weak or rapid rather than bounding.
- C. BP 146/94 mm Hg: Elevated blood pressure can be seen in various conditions and does not specifically indicate dehydration. Dehydration is more commonly associated with hypotension (low blood pressure), though this can vary depending on the severity of fluid loss and compensatory mechanisms.
Thus, monitoring urine specific gravity provides a direct measure of fluid concentration and is a reliable indicator of dehydration in clients who have experienced significant fluid loss.
