The patient who is confined to bed in the supine position has gained 5 lbs. in the last 48 hours. In which area does the nurse assess skin turgor for accurate determination of dependent edema?
A.
Foot
B.
Forehead
C.
Ankle
D.
Chest
E.
Sacrum
The correct answer and Explanation is :
The correct answer is E. Sacrum.
Explanation:
Assessing skin turgor in a patient who is bedridden and has gained weight quickly helps evaluate the presence and extent of dependent edema. Dependent edema occurs when fluids accumulate in areas of the body that are lower or dependent due to gravity, especially in patients who are immobile.
Why the Sacrum?
In a supine (lying down) position, the sacral area (lower back just above the buttocks) is particularly prone to fluid accumulation due to its position relative to the rest of the body. As the patient remains in this position, gravity causes fluids to pool in the sacral area, making it a key site for detecting dependent edema. Skin turgor assessment here involves pressing down on the skin to see if it returns to its normal position quickly. In the presence of edema, the skin may stay indented for a longer period, indicating fluid retention.
Comparison with Other Areas:
- Foot and Ankle: While these are common areas to check for edema in standing or sitting patients, they are less reliable in a supine patient because the fluid distribution changes when the patient is lying down.
- Forehead: This area is generally not used for edema assessment because the forehead is less likely to show fluid accumulation due to its position and the relatively low gravitational effect compared to dependent areas like the sacrum.
- Chest: While the chest might show signs of fluid accumulation, it is not typically the primary area to check for dependent edema in supine patients. The chest area may be more indicative of systemic fluid overload rather than localized dependent edema.
In summary, for a bedridden patient in the supine position, the sacral area is the most appropriate site to assess for dependent edema due to its tendency to accumulate fluids under the effects of gravity.
