The nurse explains that range of motion exercises are necessary so that movement improves venous circulation by:

maintaining strength in muscles.

compression of muscles on venous walls.

vasodilation.

increased metabolism.

Answer and Explanation

The Correct Answer is B

A. maintaining strength in muscles.

This is a benefit of ROM exercises, but it does not directly explain how venous return improves.

B. compression of muscles on venous walls.

Muscle contraction compresses veins, helping to push blood back toward the heart, improving venous return.

C. vasodilation.

Vasodilation increases blood flow, but doesn’t directly enhance venous return in the context of ROM.

D. increased metabolism.

Increased metabolism is a systemic benefit of exercise but is not the primary mechanism of improved venous circulation.

Correct Answer is B

Explanation

A. Use metal clips to secure the wrap:

While metal clips are commonly provided with elastic bandages, they can easily become dislodged and may cause injury. Tape or self-adhesive wraps are often safer and more secure.

B. Adjust the pressure or tension as needed:

This allows for proper circulation and comfort. Bandages should be snug but not tight, and pressure may need to be adjusted for swelling or anatomical differences.

C. Overlap turns of the bandage equally:

This is a correct technique but not the most critical factor for effectiveness and safety. Equal overlapping helps provide uniform pressure, but adjusting tension as needed is more essential.

D. Face the patient and wrap from proximal to distal:

Wrapping should always go from distal to proximal to promote venous return and reduce edema. Wrapping proximal to distal is incorrect and can impair circulation.

A. the pads should be 1/2 to 2 inches (1.3cm to 5cm) below the axilla. B. when walking, the patient will need to straighten the elbow and the wrist during weight bearing C. resting the body's weight on the axillary bar does not put pressure on vital nerves which can occlude blood vessels in the axilla causing permanent or temporary damage. D. they will need to be adjusted in both overall length and from the axillary bar to the handgrip

Correct Answer is D

Explanation

A. The pads should be 1/2 to 2 inches (1.3cm to 5cm) below the axilla

This is true and helps avoid pressure on the axilla and nerves.

B. When walking, the patient will need to straighten the elbow and the wrist during weight bearing

Elbows should be slightly flexed (~15–30 degrees); straightening the elbow and wrist fully can cause injury and reduce control.

C. Resting the body's weight on the axillary bar does not put pressure on vital nerves which can occlude blood vessels in the axilla causing permanent or temporary damage

Resting on the axillary bar can compress the brachial plexus and axillary vessels, causing nerve damage or paralysis.

D. They will need to be adjusted in both overall length and from the axillary bar to the handgrip

Proper crutch fitting includes adjusting both the overall length and the handgrip height.
