2. Oliguric/anuric (8-14 days): output < 400mL in a day, increase in BUN and creatine. Electrolyte disturbances, fluid overload since kidneys can't excrete water
3. Diuretic phase (7 to 14 days): Occurs when AKI cause is corrected, increased GFR, daily urine output > 400 mL, Possible electrolyte depletion from excretion of more water and osmotic effects of high BUN.
4. Recovery phase (months to 1 year): decreased edema, normal fluid/electrolyte balance, return of GFR to 70-80% of normal

Hip Precautions
1. Prevent hyperflexion of hip no more than 70 degrees.
2. Prevent falls
3. Elevated toilet seat
4. Keep legs straight and separated (abducted)
Knee surgery
1. Risk for: infection, blood clots, nerve damage.
2. No pillow under the knee
3. Encourage ROM
4. Pain managmenet/ good neuro assessment
Risks of Orthopedic Surgeries
1. Blood clots
2. Fat embolisms
3. infection
4. New fracture
5. dislocation
6. nerve damage
6 P's of Neurovascular assessment
PT vs OT
1. PT: lower extremity and mobility
2. OT: upper extremity and living (doing things)
Orthopedic surgery watch for
1. Wound infection
2. Venus thromboembolism
3. Fat embolism syndrome
4. Atelectasis
5. Dislocation
Amputation
1. Reasons: trauma, nonhealing wounds (diabetes), deformities, PVD, osteomyelitis
Amputation: Pre-Op or Traumatic
1. Priority assessments or cues: bleeding, hemodynamic status, emotional state, oxygenation.
2. Priority labs: arteriogram, venogram, and doppler, CBC
3. Priority interventions: control bleeding, compression bandages surgical TQ, prevent infection, control pain
4. Post OP: infection control, wound care, pain management, pt/ot
Path to a prosthetic
1. healing time
2. residual limb shaping
3. pain management
4. muscle strengthen
5. contracture prevention / ROM
Types of Shock
4 Stages of Shock
1. Initial stage: no noticeable changes, changes to cellular level
2. Compensatory: neural SNS, endocrine RAAS; increase glucose, chemical- tachypnea
3. Progressive: failure of compensatory mechanisms
4. Refractory: irreversible cell death
Shock Symptoms
1. Increased HR
2. Increased RR
3. Increased glucose
4. Decreased urine
5. Decreased blood flow to internal organs
6. Cool skin
Shock Stages Findings
Hypovolemic Shock
1. major loss of blood or fluid
2. trauma, burns, pancreatitis, gi bleed, excessive sweating, abnormal diuresis (diabetes insipidus), vomiting, diarrhea.
Diabetes Inspidius
A disorder of salt and water metabolism marked by intense thirst and heavy urination.
Diabetes insipidus occurs when the body can't regulate how it handles fluids. The condition is caused by a hormonal abnormality and isn't related to diabetes.
In addition to extreme thirst and heavy urination, other symptoms may include getting up at night to urinate or bed-wetting.
Pathophysiology of Hypovolemic Shock
1. Hypovolemia -> venous return declines -> declined preload -> low cardiac output -> hypotension -> perfusion failure -> tissue hypoxia -> organ disfunction -> multiorgan failure
Clinical manifestations of Hypovolemic shock
1. Hypotension
2. tachycardia
3. dry oral membranes
4. decreased tissue perfusion
5. Labs: BUN UP, sodium down, urine gravity up, HCT/HGB up,
Treatment of Hypovolemic shock
1. Maximize oxygen delivery
2. Restore intravascular volume, fluid resuscitation, blood transfusion
3. Control further blood loss with TQs, surgical intervention
4. Treat underlying cause
5. Support hypotension, vasoconstrictors/vasopressors
6. Monitor electrolytes and lactate
Sepsis
1. Body's extreme response to infection, spreads from original location to other tissues and can progress to organ failure then death.
2. Sepsis is curable if caught early
Stages of Sepsis
1. Stage 1 (compensatory): systemic inflammatory response, SOB, tachycardiac, extreme pain, clammy sweaty skin, clot formation.
2. Stage 2 (progressive): severe sepsis, organ dysfunction begins, confusion/disorientation, decreased urine output, abnormal cardiac function, respiratory distress.
3. Stage 3 (refectory): septic shock, dangerous drop in BP, skin pale, mottled.
Sepsis TIME
1. Temperature- higher or lower than normal
2. Infection - may have s/s of infection
3. Mental decline- confused, sleepy, difficult to rouse
4. Extremely ill - severe pain, discomfort, shortness of breath
Septic Shock and Labs and Meds
1. Labs: high or low WBC, positive blood cultures, Elevated urine gravity, Hyperglycemia
2. Meds for Sepsis: antibiotics, vasopressors, iv fluids, corticosteroids, insulin, pain meds
Treatment of sepsis
1. Prevention
2. early recognition: changes in VS
3. Send cultures: blood, urine, sputum
4. aggressively treating infection w/ antibiotics
5. aggressive fluid replacement (usually crystalloids)
6. support BP (vasopressors - norepinephrine, dopamine)
7. Monitor labs: lactate levels, glucose, WBC
8. support resp and cardiac function.
Sepsis Protocol
Post sepsis syndrome
1. affects up to 50% of sepsis survivors, physical/psychological long term effects
2. Fatigue, sleep disturbances, sob, disabling muscle joint pain, repeat infections, poor appetite, reduced organ function, hallucinations, panic attacks, depression, memory loss, difficulty concentrating.
