Amputation

• Pg 1080

Amputation

• “removal of a body part, often an extremity”

Amputation

• Common Causes– Peripheral Vascular

Disease (PVD)– Trauma– Osteomyelitis– Tumor

• osteosarcoma

Which of the following type of amputation is the most common?

A. Upper extremityB. Lower extremity

Amputation

• Reason–Relieve symptoms–h function–h quality of life

• Which of the following is the preferred type of amputation

A. AKAB. BKA

Amputation

• Most distal point

AmputationNursing Assessment

• Pre-op– Neurovascular status• CMS• Doppler • Ultrasound

AmputationNursing Assessment

• Pre-op– Function– S&S of infection• C&S• Lymph nodes

– Psych. status

Amputation

• Complications– Hemorrhage– Hematoma– Infection– Skin breakdown– Edema– Phantom limb pain– Contracture

Table Question

• What would you identify as the priority nursing diagnosis for a client who is post-op BKA?

Nrs Dx: for Amputation

• Acute pain• Disturbed sensory perception• Impaired skin integrity• Grieving • Self-care deficit• Impaired physical mobility

Acute Pain

Nrs Dx: Acute Pain

• Opioid • Evacuation • Δ position• Sandbag • Distraction

Nrs Dx: Altered Sensory Perception

• h activity• Rehab• Distraction• Rx– Analgesics– Tricyclic antidepressants– Anticonvulsants

Nrs Dx: Impaired skin integrity

• Gentle• Aseptic tech.• Diet– h protein– vitamins

• Residual limb shaping– Elastic dressing– Cast

Which of the following techniques is correct for obtaining a wound culture specimen from a surgical site?

A. Thoroughly irrigate the wound before collecting the specimen.

B. Use a sterile swab and wipe the crusty area around the outside of the wound.

C. Gently roll a sterile swab from the center of the wound outward to collect drainage.

D. Use a sterile swab to collect drainage from the dressing.

NURSING ALERT• If the cast or elastic dressing comes off, the

residual limb must be immediately wrap with an elastic compression bandage. If not, excessive edema will develop leading to a delay in rehabilitation.

• Notify the surgeon so that another cast can be applied promptly

Nrs Dx: Impaired body imageNrs Dx: Grieving

• Relationship of trust• Pt. care for limb• Independence• Realistic goals• Support systems• Referrals

Nrs Dx: Self Care Deficit

• Practice• Nursing impact

Nrs Dx: Impaired physical mobility

• Prevent contractures• Avoid– Abduction– External rotation– Flexion

• Prone*• ROM• Upper body exercises

Nursing Alert• The residual limb should not be

placed on a pillow because a flexion contracture of the hip may result.

A client hospitalized with MRSA (methicillin-resistant staph aureus) is placed on contact precautions. Which statement is true regarding precautions for infections spread by contact? A. The client should be placed in a room with

negative pressure. B. Infection requires close contact; therefore, the

door may remain open. C. Transmission is highly likely, so the client should

wear a mask at all times. D. Infection requires skin-to-skin contact and is

prevented by hand washing, gloves, and a gown.

A client who is admitted with an above-the-knee amputation tells the nurse that his foot hurts and itches. Which response by the nurse indicates understanding of phantom limb pain?A. "The pain will go away in a few days.“B. "The pain is due to peripheral nervous system

interruptions. I will get you some pain medication."

C. "The pain is psychological because your foot is no longer there."

D. “The pain and itching are due to the infection you had before the surgery."

The primary reason for rapid continuous rewarming of the area affected by frostbite is to:A. Lessen the amount of cellular

damage B. Prevent the formation of blisters C. Promote movement D. Prevent pain and discomfort

You are assigned to care for a patient with a Below the Knee Amputation (BKA). Among the patient’s orders is one which states that the patient should be placed in the prone position twice daily. The nurse knows that the reason for this is:A. Changing the patient’s position will help to

prevent skin breakdownB. To observe the stump for signs of infectionC. To assist the patient in doing ROM (Range of

Motion) exercisesD. To stretch the flexor muscles and prevent

flexion contractures
