A

When the proximal (upper) 1/3 of the femur is injured.

23
Q

What is the most commonly noticed sign of a hip fracture?

A

24
Q

What is the Tx for a hip fracture?

A

●Immediate surgery is the standard of care.
●May initially be stabilized with Buck’s traction.

25
Q

What are the surgical options for Hip fractures?

A

What is the post-op/Nursing Management for Hip Fractures?

A

●Decrease edema
●Use pillow between legs when turning
●Encourage use of trapeze bar for repositioning
●Do not turn on affected side!
●Teach positions that can cause dislocation (pg 1464)

*assess site for REEDA, 6 P’s, Vitals, I&O’s, IS, Pt up/walking 6hrs (1st w/walker, then cane- within weeks)

27
Q

What are complications of Hip Fractures?

A

●Dislocation-teach Pt signs (external rotation, shortening, severe pain, lump on butt area)
●Nonunion
●Avascular necrosis
●Osteoarthritis
●Affected leg may be shorter- cane or shoe lift may be needed for safety

28
Q

What are are some Surgical Joint Procedures?

A

●ORIF
●Closed reduction with fixation
●Meniscectomy-(excision of part of the meniscus -cushion around knee. Done by arthroscopy.)
●Arthroplasty- total or joint
●Amputation

29
Q

What is the difference between Arthroplasty vs. Arthroscopy?

A

Arthroplasty is fully cut open vs. arthroscopy is smaller incisions and done with scopes (small cameras/tools)

30
Q

What is the post-op care for a knee Arthroplasty?

A

●Compression dressing
●Knee immobilizer
●PT right away & outpatient after d/c.
●Anticoagulants Parental abx (10-14 days)

31
Q

What is the post-op care for Total Hip Arthroplasty?

A

●Replacement of hip joint to relieve pain and restore function for patients
●Prosthesis (implant) Management of care is same as hip fracture management :

A

●Hip/ Total Knee
● prophylactic anticoagulant drugs
●ROM (all extremities for circulation)

34
Q

What is compartment syndrome & what are the causes?

A

●condition where swelling causes increased pressure within limited space (muscle compartment)
● long bone fracture, excessive soft tissue damage, crush injuries

●causes: casts, restrictive dressings, IV infiltration, closing fascia too early

35
Q

Nursing Considerations for Compartment Syndrome?

A

● At least one of the P’s will be present…especially PRESSURE.
●early recognition/ prompt dx is critical to prevent permanent damage to muscles and nerves.
●Relieve pressure
●DO NOT elevate the leg above the heart. (We need circulation to the area)
●DO NOT apply cold compress. (Vasoconstriction)
●Fasciotomy: surgical decompression may be needed

36
Q

What is Fat Embolism Syndrome? What are the clinical manifestations/nursing considerations?

A

●characterized by fat globules entering the circulatory system from fractures.

Clinical manifestations:
●Respiratory distress
●Petechiae
●No labs test will diagnosis

●Nursing considerations: supportive and related to managing symptoms
●Early recognition is crucial to prevent death!

37
Q

What is rhabdomyolysis? What are the S/S? Test question for sure

A

●Syndrome caused by breakdown of damaged skeletal muscle cells.
●Releases myoglobin into bloodstream

●S&S: dark reddish or brown urine (kidney failure), muscle pain, muscle weakness, elevated Creatine kinase (tx: hydration)

38
Q

What are the most common reasons for Amputations and their diagnostic studies/types?

A

● Most common reason: PVD, diabetes Pt’s

●Dx studies: arteriography (vascular test), doppler studies, and a venography (tells info about circulation.)

●Types:
●AKA (above knee)
●BKA (below knee)

39
Q

What are nursing considerations for amputee patients? 

A

● A lot of psychosocial care (include family)
●Assess dressing and change as needed. (Dr will do 1st change!)
●Keep surgical torniquet available for emergency use
●Prevent flexion contractures (ROM, avoid sitting for long periods, lay prone for 30min 3-4x/day)
●Proper bandaging
●PT with crutch walking

40
Q

What is some Pt education for amputations?

A

•infection/what to look for (Temp, redness, swelling, drainage, smell(
•discourage semi-fowler’s
•educate about phantom limb pain and how to tx it.
•asses for skin breakdown/ irritation

41
Q

What are some medications for pain relief? (NSAIDs - what are they? Adverse effects?)

A

NSAIDS: Work by inhibiting COX, the enzyme that form prostaglandins. This leads to decreased inflammation and pain.

●Ibuprofen/Motrin
●Toradol
●Naproxen (look for blood in stool)

Adverse Effects: Gi bleeds, constipation, kidney problems, stomach upset/ulcers, HTN

42
Q

What are some medications for pain relief (OPIODS - COMBO ANALGESICS, adverse effects/ nursing considerations?)

●Morphine
●Fentanyl
●Dilaudid
●Hydrocodone
●Oxycodone

Combo Analgesics:
●Norco
●Percocet

What are some medications for pain relief? (MUSCLE RELAXANTS- what are they, adverse effects?, nursing considerations)

A

●Muscle Relaxants: used to treat localized muscle spasms after injury or surgery

●Baclofen
●Soma
●Flexeril

●Adverse effects: hepatotoxicity, addiction

44
Q

What are some post amputation considerations?

A

●PT
●learning to walk with prosthesis (if applicable)
●learning to walk with crutches
●balance

Psychosocial:
●grieving a loss

●financial strain (very common)
*Table 62.14 (pt/caregiver teach amputation)

45
Q

Back pain overview

A

●Back pain is the 2nd most common cause of pain (1st is headache)
●Acute (4wks or less) vs. Chronic (more than 3 months)
●Radicular (sciatica- nerve root) vs. Referred (not related to back- kidneys for ex.)
●Good body mechanics prevent injury

46
Q

What is acute lower back pain? (Causes, Tx?)

A

●Last 4 weeks or less
●Caused by trauma or activity
●Symptoms often appear 24 hours or later due to the gradual increase in pressure on the nerve or disc

●Tx: gabapentin, steroids, opioids, NSAIDs
●Alternative tx: (hospital): hot/cold compress, binder, rest 1-2 days. (Home): stretch, massage, acupuncture, cupping

47
Q

What is chronic lower back pain? (Causes, Tx?)

A

Last more than 3 months, or involves repeated episodes
●Cause can be undetermined

●Common causes:
●Degenerative conditions
●Bone diseases (do x-ray, CT, MRI)
●Weakness from scar tissue or injury
●Chronic strain
●Congenital spine problems

●Tx: similar to acute:
●NSAIDS, antidepressants, Neurontin

48
Q

What are the diagnostic studies often used?

A

●X-ray
●MRI
●CT scan
●EMG (electromyography/ severity of nerve irritation)
●Straight leg test
●Crossed SLR test

49
Q

What are two surgical treatments for back pain?

A

●Laminectomy: common, traditional procedure for lumbar disc disease.

●Discectomy: small instruments used to decompress the nerve root. Minimal bleeding, easier recovery. (1-2 days of rest)

50
Q

Explain Spinal Disc Replacement

A

●Provides ability to replaced an injured disc w/o performing a fusion surgery.
●Possibly slows degenerative process in the adjacent discs.
●Risk for failure of correction due to the synthetic material
●Not commonly done (to replace the whole disc)

51
Q

Explain Spinal Disc Fusion

A

● Fusion may be recommended for patient’s with instability (won’t be recommended for older Pt’s)
●As body heals, the bone graft and vertebrae grow into one unit (or become fused)
●This stabilizes the vertebrae which may decrease pain with movement

52
Q

What is the Post-op Care for back surgery?

A

●Neuro checks, VS
●Skin checks
●Wound assessment
●Halo sign (blood on dressing, circle and date, call Dr immediately could be emergent bleed)
●Keep supine x 24 hours if possible
●Get help turning & repositioning!
●Discharge teaching (prevent infection, importance of ambulation, limitations!!)
