During a below-the-knee amputation, what is the primary focus of the surgical technique?
Preserving the ankle joint
Removing all muscles from the affected limb
Creating a cosmetic incision line
Resecting the tibia and fibula bones
The Correct Answer is A
During a below-the-knee amputation, the primary focus of the surgical technique is to preserve the ankle joint whenever possible. This allows for better functional outcomes and facilitates the use of a prosthetic device.
b. Removing all muscles from the affected limb: While some muscle tissue is removed during amputation, the goal is not to remove all muscles. Some muscles are retained to provide coverage over the bone stump and to facilitate prosthetic fitting.
c. Creating a cosmetic incision line: While cosmetic considerations may be taken into account, the primary focus of the surgical technique is not solely on creating a cosmetic incision line. The incision is made to ensure appropriate tissue healing and to prevent complications.
d. Resecting the tibia and fibula bones: In a below-the-knee amputation, the tibia and fibula bones are typically resected to the appropriate level to accommodate the prosthetic device, but the primary focus is on preserving the ankle joint when possible.

Correct Answer is C
Explanation
The appropriate method of positioning the residual limb in the post-operative period for a patient who underwent a below-the-knee amputation is to elevate the residual limb on a pillow. Elevating the limb helps reduce swelling and promotes venous return, which can enhance healing and prevent complications.
a. Keep the residual limb in a dependent position: Keeping the residual limb in a dependent position (hanging down) can impede venous return and increase swelling. It is not the recommended position for post-operative care.
b. Maintain the residual limb in a flexed position: Keeping the residual limb in a flexed position may increase pressure on the surgical site and hinder proper wound healing. A flexed position is not the recommended post-operative positioning for the residual limb.
d. Keep the residual limb in a neutral, flat position: While keeping the residual limb in a neutral, flat position is generally recommended for some post-operative care, elevating the limb on a pillow is preferred in the immediate post-operative period for below-the-knee amputation to reduce swelling and promote healing.
Correct Answer is C
Explanation
Inspecting the skin under the prosthetic device daily is essential to prevent skin breakdown and pressure ulcers. Continuous pressure and friction from the prosthetic device can cause skin irritation and breakdown, and early detection allows for timely intervention and prevention of complications.
a. Applying a topical antibiotic to the residual limb daily: Applying a topical antibiotic daily is not recommended unless specifically prescribed by the healthcare provider for a wound or infection. Routine use of topical antibiotics can lead to antibiotic resistance.
b. Massaging the residual limb with lotion to improve circulation: Massaging the residual limb with lotion may be beneficial for comfort, but it is not a preventive measure for skin breakdown. Excessive massage can cause skin irritation.
d. Wearing a compression bandage over the prosthetic device: While compression bandages may be used as part of post-operative care, wearing a compression bandage over the prosthetic device is not a standard preventive measure for skin breakdown.
