The nurse understands that sequential compression devices and compression stockings are used for which of the following?
Protect the muscles of the lower extremities from atrophy.
Keep the blood from pooling in lower extremities to avoid clots.
Keep the patient from getting sores on the skin.
Keep the patient’s joints in working order.
The Correct Answer is B
A. Protect the muscles of the lower extremities from atrophy:
This statement is not the primary purpose of sequential compression devices (SCDs) and compression stockings. While these devices can help maintain muscle tone by promoting blood circulation, their primary function is to prevent blood pooling and reduce the risk of deep vein thrombosis (DVT).
B. Keep the blood from pooling in lower extremities to avoid clots:
This is the correct purpose of sequential compression devices and compression stockings. They are designed to promote venous return and prevent blood from pooling in the lower extremities, thereby reducing the risk of blood clots, especially in individuals at risk for deep vein thrombosis (DVT).
C. Keep the patient from getting sores on the skin:
Preventing sores on the skin is not the primary purpose of these devices. While improved circulation may contribute to skin health, preventing skin sores is not the primary therapeutic goal of SCDs and compression stockings.
D. Keep the patient’s joints in working order:
Maintaining joint function is not the primary purpose of sequential compression devices and compression stockings. These devices primarily focus on promoting venous circulation and preventing complications related to blood pooling and clot formation.

Correct Answer is A
Explanation
A. Tie it to the bed frame with a quick release knot.This option is correct because securing the restraint to the bed frame ensures that the client cannot easily remove it, while a quick release knot allows for rapid removal in case of an emergency.
B. Strap the restraint with a square knot to the head of the bed.While a square knot may be secure, it is not considered a quick-release method, which is essential for the safety of the client.
C. Use a quick release knot to tie the restraint to the side rail.Tying a restraint to the side rail can pose a risk because if the side rail is lowered, it may create a situation where the restraint is loose or ineffective. It is safer to secure it to the bed frame instead.
D. Assist with range of motion at least every 3 hours.While providing range of motion is important to prevent complications from immobility, it does not address how to secure the restraint itself. Regular assessments and range of motion exercises should be part of the overall care plan but are not directly related to securing the restraint.
Correct Answer is A
Explanation
A. Discard the bottle of saline and obtain a new bottle:
Sterility is crucial when performing a sterile procedure. If the saline solution has been opened for 48 hours, it may no longer be considered sterile. The nurse's priority is to use a fresh, sterile bottle of saline to ensure aseptic technique during the dressing change.
B. Lip the bottle of saline over the trash before pouring into the field:
Lipping the bottle over the trash is not a recommended practice. Pouring the saline over a sterile field is the appropriate way to maintain the sterility of the solution.
C. Pour the saline at least 6 inches above the sterile field:
While pouring from a height can help generate a flow without contamination, the priority in this situation is to address the sterility of the saline. It's crucial to start with a new, unopened bottle.
D. Be sure the label is facing the palm before pouring:
The orientation of the label is not the primary concern in this scenario. The primary concern is the sterility of the saline solution.
