Study Notes

  • Acute Renal Failure (ARF) is a self-limiting condition characterized by a sudden loss of kidney function, affecting urine excretion, nitrogenous waste removal, and fluid, electrolyte, and pH balance maintenance.
  • ARF is categorized into pre-renal, intra-renal, and post-renal types and typically resolves after addressing the underlying issue.

Causes of Pre-renal AKI

  • Hypovolemic shock can lead to pre-renal AKI.
  • Vasodilation can cause pre-renal AKI.
  • Third spacing of fluids can result in pre-renal AKI.
  • Dehydration is a cause.
  • Sepsis and Disseminated Intravascular Coagulation (DIC) are potential causes.
  • Heart failure (HF) can lead to pre-renal AKI.
  • Hypoxia from any origin.
  • Trauma can induce pre-renal AKI.

Individuals at Risk for Pre-renal AKI

  • Post-surgical patients are at risk.
  • Cardiac pathology.
  • Trauma patients.
  • Burn patients.
  • Anaphylaxis.

Causes of Intra-renal AKI

  • Direct trauma to the kidneys.
  • Acute glomerulonephritis.
  • Acute pyelonephritis.
  • Hemoglobinuria/myoglobinuria.
  • Damage to other cells/tissues.
  • Blood transfusion reactions.
  • Nephrotoxins exposure to chemicals, organic solvents, and pesticides can cause intra-renal AKI
  • Exposure to heavy metals like mercury, arsenic, and lead can cause intra-renal AKI.
  • Certain drugs, including aminoglycosides, NSAIDs, acetaminophen, antineoplastic agents, vancomycin, neomycin, cocaine, lithium, contrast media, and cyclosporine can cause intra-renal AKI
  • Snake (copperhead) and centipede venom can cause intra-renal AKI

Causes of Post-renal AKI

  • Obstruction in the lower urinary tract, or external compression in the abdomen, outside the renal/urinary system.

Treatment of Pre-renal AKI

  • Management focuses on correcting the underlying cause (e.g., hypovolemia, decreased cardiac output) rather than directly treating the kidney itself.
  • Prevention is the most effective approach.

Treatment of Intra-renal AKI

  • Correct the underlying problem to treat the issue.
  • Infections can complicate treatment.
  • Ensure the tubular membrane is intact to aid recovery.
  • Patient survival depends on managing imbalances.

Treatment of Post-renal AKI

  • Relieve the obstruction.

General Interventions for ARF

  • Monitor for potential causative agents.
  • Administer medications and assess their effectiveness.
  • Implement dietary restrictions.
  • Strict monitoring of intake and output (I&O) and weight measurements.
  • Provide supportive care for both the patient and their family.
  • Dialysis may be necessary.
  • Dopamine (renal dose) and diuretics may be administered.

ARF Signs and Symptoms

  • Oliguria.
  • Increased levels of Blood Urea Nitrogen (BUN).
  • Increased creatinine levels.

Dialysis Facts

  • The solution used is sterile.
  • Electrolytes, heparin, antibiotics, and insulin can be added to the solution.
  • Glucose and osmolarity are adjusted to facilitate fluid removal.

Hemodialysis

  • A process where dissolved particles diffuse from one compartment to another through a semi-permeable membrane.
  • It cleanses accumulated wastes, removes excess fluids, and eliminates metabolic by-products.
  • Maintains/restores the buffer system and electrolyte levels.

Complications of Hemodialysis

  • Hypotension.
  • Shock.
  • Muscle cramps.
  • Electrolyte changes.
  • Sepsis.
  • Blood loss.
  • Hepatitis.
  • Disequilibrium syndrome.
  • Dialysis encephalopathy.

AV Fistula Assessment

  • Auscultate for a bruit and palpate for a thrill.
  • These findings indicate proper functioning.

Types of Peritoneal Dialysis

  • Continuous Ambulatory Peritoneal Dialysis (CAPD).
  • Automated Peritoneal Dialysis (CCPD).

Peritoneal Dialysis

  • The peritoneum serves as the dialyzing membrane.
  • Diffusion and osmosis principles are used to exchange fluids and solutes.
  • The peritoneal cavity has an excellent blood supply for effective exchange.

Complications of Peritoneal Dialysis

  • Peritonitis.
  • Abdominal pain.
  • Insufficient flow.
    • Check for kinks or clogging.
    • Reposition the patient and massage the abdomen to improve flow.
  • Leakage around the catheter site.

  • Hold antihypertensives and sedatives before the procedure.
  • Hold medications that can be filtered out during dialysis.
  • Monitor for post-procedure complications.

Lab Result Indicative of Renal Disease

  • Elevated creatinine (CRE).

Best Way to Monitor for Fluid Retention

  • Weight and BP monitoring.

Cirrhosis

  • A chronic liver condition characterized by inflammation, fibrotic changes, and significant loss of functional liver tissue.
  • Fatty infiltration leads to disorganization of liver structures as interconnecting fibrous bands form.

Major Cirrhosis Complications

  • Ascites.
  • Varices.
  • Encephalopathy.

Ascites

  • Increased abdominal girth due to fluid accumulation.
  • Often characterized by skinny extremities and a large abdomen.
  • Fluid wave test can be used to determine presence.

Ascites Treatment

  • Transjugular Intrahepatic Portal-systemic Shunt (TIPS) procedure, involving a stent to keep the vein open.
  • Restriction of sodium intake aids in management.
  • Paracentesis may need to be performed because the risk of infection is high. Give Albumin if has not been given in past 5 years.

Primary Assessment for Burns

  • Focus on airway and breathing (ABCs).
  • Thermal injuries can cause upper airway injury, pulmonary injury, carbon monoxide poisoning, or a combination of these.

Signs and Symptoms of Upper Airway Injury

  • Facial burns.
  • Singed nasal hairs.
  • Progressive hoarseness.
  • Stridor.
  • Inability to swallow.

First Degree Burn

  • Caused by short flash exposure to high temperatures or prolonged exposure to lower temperatures (e.g., sunburn).
  • Involves the epidermis only.
  • No blistering occurs.
  • No scar remains after healing.
  • Only redness, mild edema, and increased sensitivity to heat are present.

Superficial Partial Thickness Burn (Second Degree)

  • Affects the upper one-third of the dermis.
  • Blood supply remains intact, resulting in a pink and moist wound appearance.
  • The wound will blanch.
  • Blisters will form.
  • Painful due to intact nerves.
  • Heals in approximately 10-21 days.
  • No scarring, but minor pigment change may occur.

Deep Partial Thickness Burn (Second Degree)

  • Extends deeper into the dermis.
  • No blisters due to a thick layer of dead tissue that adheres to the dermis.
  • The wound bed is red and dry.
  • Fewer patent blood vessels are present.
  • White areas may appear in deeper parts of the burn.
  • Blanching may be slow or absent.
  • Less pain due to nerve ending damage.
  • Heals in 2-6 weeks with scarring.

Healing Protocol for Second Degree Burns

  • Proper care will promote healing without grafting in most cases.
    • Wash with soap and water twice daily.
    • Apply antibiotic ointment (Bacitracin vs. Silvadene).
    • Use a non-adherent dressing.
    • Apply a dry sterile dressing.

Third Degree Burn

  • A deep burn involving both the dermis and epidermis, as well as the subcutaneous layer.
  • Skin appears white, leathery, or charred with no blanching.

  • No pain is felt due to complete destruction of sensory nerve fibers.
  • Will not heal on its own and requires grafting.

Circumferential Burn

  • Completely surrounds a body part, such as the chest.
  • If it's a 3rd degree burn, the eschar is tight and edema underneath restricts breathing.

Treatment for Circumferential Burn

  • Escharotomy to relieve pressure and improve oxygen flow and breathing. Incision through the eschar to decrease chest pressure leading to inc O2 flow and unrestricted breathing.

Electrical Burns

  • Caused by sources such as lightning or direct/alternating current.

Anticipation of Care Needs

Age-Related Variances-Pediatric:

  • Most common - head trauma - large heads and higher center of gravity.
  • Smaller mass - energy of trauma effects more tissues with less fat; multi-organ injuries common.
  • Skeleton more elastic absorption and protection capability decreased.
  • Sensitive to hypoxia - most common cause of arrest situation.

Pregnant

  • Anatomical changes:
    • Bladder higher
    • Large uterus causes changes in position and protection of vital organs like liver and spleen
    • Decreased lung volume
  • Hemodynamics Cardiac output increased, decreased H/H/anemia.
  • Normally hypercoagulation state so prone to DIC if stressed.
  • Leads to increased bleeding risk.

Geriatric

  • Delayed reaction time
  • Gait disturbances
  • Decreased sensorium
  • Normal aging of organ systems
  • Chronic diseases
  • Poly pharmacy
  • Decreased reserves to stress

Normal ICP

Normal ICP is 10 mm Hg (upper threshold 20 mm Hg)

Fluids and Intracranial Pressure (ICP)

  • Avoid giving hypotonic fluids to patients with increased ICP.
  • Hypotonic fluids enter the cells and increase cerebral edema.

Causes of Cerebral Edema

  • Lesions (tumors, abscesses, clots).
  • Injury (contusions, hemorrhage, post-traumatic brain swelling/inflammation).
  • Surgery.
  • Infection.
  • Toxins (lead and arsenic).
  • Systemic metabolic conditions (liver and renal failure).

Early Signs/Symptoms of Increased Intracranial Pressure (IICP)

  • Headache.
  • Nausea/vomiting.
  • Amnesia for events.
  • Altered level of consciousness (LOC).
  • Restlessness, drowsiness, changes in speech, loss of judgment.

Late Signs/Symptoms of Increased Intracranial Pressure (IICP)

  • Dilated, nonreactive pupil.
  • Unresponsiveness to verbal or painful stimuli.
  • Abnormal posturing patterns (flexion, extension, flaccidity). Changes in respiratory pattern.

Very Late Signs/Symptoms of Increased Intracranial Pressure (IICP)

  • Cushing's Triad:
    • Increased systolic pressure with widening pulse pressure.
    • Slow, bounding pulse.
    • Slow, irregular respirations.
  • Changes in body temperature.
  • HERNIATION and DEATH

Managing ICP

  • TREAT PRIMARY CAUSE!
  • Reduce edema formation
    • Diuretics (mannitol)
  • Dexamethasone (decadron) for tumor
  • Hypertonic saline (2-3%)
    • Check serum na+
  • Reduce stimuli
  • Reduce CO2 (hyperventilation) reduces venous engorgement and causes vasoconstriction
    • BE CAREFUL decreased blood flow can also cause anoxia and further tissue damage

RN Actions for Patient with Cerebral Edema

  • Serial vital signs
  • I & O
  • Cranial checks
    • Pupil size, pupil response to light, eye movement, hand grasps

  • High-dose steroids to reduce swelling
  • Warmth

Causes of Autonomic Dysreflexia

  • Hyperreflexia
  • Usually seen with SCI at T-6 or higher and represents uninhibited sympathetic discharge
  • Some stimuli (bladder distension, bowel impaction, labor, temperature change, pain, UTI) stimulates excessive sympathetic nervous system stimulation below lesion
  • Systemic vasoconstriction causes sweating, anxiety, hypertension, blurred vision, headache
  • Parasympathetic nervous system attempts to compensate but inadequate

Untreated Autonomic Dysreflexia

If left untreated can lead to:

  • CVA
  • Renal failure

  • Vasodilators

Nursing Interventions with Spinal Cord Injury

  • Serial vital signs
  • I & O
  • Cranial checks
    • Pupil size, pupil response to light, eye movement, hand grasps
  • WATCH IV FLUIDS!
  • Reverse Trendelenburg position
  • Avoid/reduce stimuli
    • Suctioning, movement, painful procedures
  • Assess/stabilize effective airway
  • Immobilize to prevent further damage
  • Assess level of cord injury
  • Assess for autonomic dysreflexia
  • Stabilize spine
    • Braces/surgery
  • Psychological assessment

US Federal Transfer Law: Emergency Medical Treatment and Active Labor Act (EMTALA)

  • Patients must be medically screened and once an emergency medical treatment is determined, the patient must be stabilized.
  • Unstabilized patients may be transferred if the patient requests in writing and the physician documents that the benefit of transfer outweighs the risk of not transferring.
  • ALWAYS STABILIZE A PATIENT BEFORE TRANSFERRING EVEN IF YOUR CENTER DOESN'T SPECIALIZE, YOU MUST STABILIZE FIRST.

Interfacility Transfer Protocols and Procedures

Electrical Injury

  • For a client experienced an electrical injury with an entrance wound on the left hand and an exit wound site on the left foot the priority assessment data that should be obtained from client immediately on admission is heart rate and rhythm (ABCs).

Arteriovenous Fistula

  • The best way to check for patency of the arteriovenous fistula for hemodialysis is to palpate the fistula throughout its length to assess for a thrill.

Arteriovenous Fistula (AV) Education

  • In a client with fistula make sure client knows to check for the thrill, bruit, peripheral circulation, and ensure they cannot access ONLY ASSESS fistula

Caring for Head & Neck Trauma

  • When caring for a client with a head and neck trauma following a vehicular crash, the nurse's initial action is to immobilize the cervical area.

Peritoneal Dialysis Color

  • If you are caring for a client who is undergoing peritoneal dialysis and note the color of the returned fluid to appear cloudy and slightly pink-tinged, then the best action is to stop the dialysis flow and notify the health care provider.

Kidney Dysfunction

  • Prerenal = Before Kidneys (cardiac and fluid related).
  • Intrarenal = Within Kidneys (Infection and stone).
  • Postrenal = After Kidneys (Something Blocking Flow; 45 Y/O with Renal Calculi in Ureters).

ABCDE Sequence Trauma

  • A jaw thrust chin lift maneuver is used for airway purposes.
  • Assessing respirations, looking for symmetry in chest wall, put on O2, is the next step once the airway if established.
  • IV access is the next step after the airway and breathing are secured.
  • Disability assessment (APVU, GCS) is next.
  • Finishing up with removing clothing.
  • Then followed by a full assessment→ VS, adjuncts, Foley, etc.

Burn Patient Assessment

  • With a burn patient assessment a finding of inhalation injury would be a brassy cough.

Expected Outcome With Stat Dose of Mannitol (Inc. ICP)

  • (SATA) (Select all that apply) -Increase intravascular fluid volume
  • Improvement in Glasgow Coma Scale (GCS)
  • Increase urine out put

Increase Potassium (K+)

  • Medication of choice with hyperkalemia is Kayexalate.

Fluid Volume Determination

  • The best way to determine fluid volume and Na+ status with CRF (Chronic Renal Failure) is daily weight and BP

Burn Patient Assessment

  • When a client is admitted to unit after being trapped in house fire and has experience singed hair, black sputum, with carbon monoxide poison then the assessment of greatest choice is Carboxyhemoglobin levels.

IV Pump Calculation

  • If Pt with 500 cc bag to infuse at 0.7 mL/min… Then following would be how to calculate how long for infusion to be completed. -0. 7 (60) = 42 cc/hr 500/42 12 hrs = is answer.
  • With liver disease lab values increase with the levels of Ammonia
  • With kidney disease labs increase with levels of Creatinine
