I. CASE STUDY--CHEMOTHERAPY:

 

Four months ago, Mr. J.F. , age 45, was diagnosed with Hodgkin's Disease, Stage IIIB, after a visit to his doctor and referral to an oncologist with complaints of weight loss, fever, night sweats, and progressive shortness of breath. A CT scan showed mediastinal and peritoneal lymph node involvement. Physical exam was significant for splenomegaly and enlarged inguinal nodes. A lymph node biopsy showed Reed-Sternberg cells. A staging laparotomy was done along with a splenectomy. After sufficient healing had taken place, radiation treatment was carried out over several weeks. Now, Mr. J.F. is back for his course of chemotherapy. LFTs and CBC are WNL, as are PT and PTT. Mr. J.F. is 6' tall and 160 lbs.

The following schedule of chemo drugs will be given together as a "cycle". The cycle is administered for the first 2 weeks followed by a resting or recovery period of 2 weeks:

 

*MOPP

M = Mechlorethamine(nitrogen mustard) 6mg IV/m2 on days 1 and 8

 

O = Oncovin(vincristine) 2.0mg IV/m2 on days 1 and 8

 

P = Procarbazine(Matulane) 100mg po/m2 continuously days 1 through 14

 

P = Prednisone 40mg po/m2 continuously days 1 through 14(only during cycles 1 and 4)

 

 

After the recovery period, the ABVD regimen will be administered (on one day) followed by a 2-week recovery period:

 

*ABVD

 

A = Adriamycin(doxorubicin) 25mg IV/m2

 

B = Bleomycin(Blenoxane) 10units IV/m2

 

V = Vinblastine(Velban) 6mg IV/m2

 

D = Dacarbazine (DTIC) 375mg IV/m2

 

Before each round, Mr. J.F. will be premedicated with Zofran 100mg. IV, Benadryl 50mg. IV and Dexamethasone, 4mg IV. All medications will be given through a PICC line which was previously inserted for this purpose.

 

 

Questions:

 

1. What is the rationale for ordering the baseline lab work?

 

2. Why are chemo drugs given in combinations and in "cycles"?

 

3. How is the dosage determined? The route?

 

4. What is the reason for the premedication?

2. Case Study--Chest Trauma: Pulmonary Contusion, Flail Chest, Pneumothorax, Cardiac Tamponade, ARDS

 (Review notes on Chest Trauma? Click here!)

Mike Arnold, a 19 y.o. male, is brought into the ER following a MVC(Motor Vehicle Crash) in which he, the driver, sustained blunt trauma to the anterior trunk from striking the steering wheel and dashboard. The patient is alert, short of breath, and c/o acute chest pain, especially on the right. He is on a backboard with cervical spine restraint, and has O2 @ 3l/min. via N/C and one peripheral I.V. line with Ringer's running at 125cc/hr. As he is being taken to Trauma Room 1, the paramedics report that his latest baseline assessment shows: GCS=15, B/P 90/60, P=130 regular, R=30, shallow with paradoxical breathing and hemoptysis present, O2 sats of 93, and no other apparent injuries except for the chest trauma and possible abdominal trauma. The police found an empty six pack in the car. Blood is drawn for ABGs, CBC, Chem 21, Type and cross for 4 units, and a Medical Blood Alcohol level. After initial assessment, the ER team prepares to insert a chest tube on the right and perform a peritoneal tap. Cross table C-spine and chest films are ordered. Abdominal series is ordered with pending CT of abdomen without contrast depending on the results of the abdominal series. All of a suddent, the patient yells, "I have to throw up. . . ."

 

What should this initial ER assessment include, and what interventions will be immediately necessary?

 

 

 

What would you expect the blood gases to show?

 

 

What are paradoxical respirations and what would you suspect as the cause in this case? What about the etiology of hemoptysis?

 

 

What assessments would lead up to the decision to place a chest tube?

 

After the chest tube is inserted, 200cc of blood drains from the chest into the autotransfusion/chest drainage system. The chest x-ray that was taken indicates a pulmonary contusion, fractures of the ribs 1 thru 4 on the right hemithorax, and a proper placement of a chest tube and jugular central line. C-spine films are negative. The patient has been medicated for pain with I.V. MS, 3mg, and reports a decrease in pain from "8" to "5" within minutes.

Fifteen minutes following this report, the patient's LOC deteriorates to obtunded with withdrawal to pain, B/P 85/70, P=105, irregular, R=14 and slowing. Cardiac monitor shows sinus tachycardia with PVCs, and O2 sats are now 89. CV exam reveals muffled heart sounds, JVD, and faint peripheral pulses. Skin is cool and moist. Urinary output decreased to 25cc. in last hour. The girlfriend arrives and becomes hysterical in the patient's cubicle when she sees him.

 

What may be happening to the patient at this point?

 

 

What is the expected treatment?

 

 

What nursing interventions are necessary?

 

 

 

After these emergency interventions, Mike stabilizes enough to be taken up to the O.R. for exploratory surgery to control the bleeding and repair injured structures. Postoperatively, he is taken to ICU intubated on a Mechanical Ventilator with the following settings: FiO2= 100%, Vt(Tidal Volume)=800, Respiratory Rate=10 and Mode=SIMV(Synchronized Intermittent Mandatory Ventilation). After an hour, despite 100% O2, Mike's ABGs are: ph=7.32, pCO2=55, HCO3=17 and pO2=50; O2 sats=88. Monitor shows sinus tachycardia with occasional PVCs. A stat chest x-ray reveals patchy infiltrates. The PAWP is 18. B/P is 90/50 and being maintained with a Dopamine drip. The high pressure ventilator alarm continues to trigger despite the fact that Mike's airway is kept cleared of secretions with p.r.n. suctioning and despite the fact that he is sedated.

 

What does this total picture suggest?

 

What is causing the high pressure alarm to trigger despite a clear airway in a sedated patient?

 

 

What treatment would be initiated at this point?

 

 

What is PEEP and give the rationale for its use?

 

 

What are the complications of Mechanical Ventilation?

 

 

What are nursing care priorities for a patient with an endotracheal(ET) tube on a ventilator?

 

 

Calculate the following: Order: Dopamine 10mcg/kg/min to maintain B/P above 90 systolic(Mike is 176 lbs.)

Supply: 400 mg Dopamine in 250cc D-5-W. Set pump at: _____cc./hr.

 

 

After 10 days, Mike is improving slowly, and has received multiple infusions of TPN, lipids, antibiotics, and blood products. However, he cannot be weaned off the ventilator at this time, so a decision is made to do a tracheotomy for airway management until the weaning process can be completed. He is alert at this time and appears anxious.

 

How would you explain why he needs the tracheotomy procedure?

 

 

 

What other teaching would you initiate at this time?

 

How would you give him emotional support?

3. Case Study--Neuro Trauma and Increased Intracranial Pressure:

 

Situation: Two days ago, Mr. John Maitland, age 23, was involved in an MVC(Motor Vehicle Crash) and incurred injuries resulting in closed head trauma; a right pneumothorax, and blunt abdominal trauma. He currently has a GCS(Glasgow Coma Scale) of 7 (eye opening=1; verbal=1; motor=5), and "dolls eyes" are present. You are assigned to take care of him today in the ICU. John is lying in bed with eyes closed when you come into his cubicle. Her has a intraventricular catheter in place connected by pressure tubing to an ICP monitoring system, an arterial line, a Swan-Ganz pulmonary artery catheter, an N/G tube currently draining coffee ground material and a foley catheter. He is on a hypothermia blanket and is orally intubated on a ventilator. He also has a right chest tube in place to water seal drainage and set at -20cm suction. A peritoneal tap was done in the ER to determine if exploratory surgery was necessary; it was negative. His medications include:

 

Pepcid 20mg I.V. b.i.d.

Lasix 40mg I.V.P. b.i.d.

Claforan 1 Gm. I.V. q8h.

Gentamycin 400mg. I.V. q8h.

Maalox 30cc. thru N/G q4h.--clamp tube for 30 min. afterwards

Thorazine 25mg. I.M. q3h. prn for shivering

Codeine gr. i I.M. q4h. prn for pain

Versed 0.2mg./kg. I.V.P. q2h. prn for agitation

Mannitol 1.5 Gm./kg. of a 25% solution over 30 min. for sustained ICP q4h. prn

Dopamine 10mcg/kg/min, titrate to keep CPP above 60mmHg.

Ringers Solution 1000cc. I.V. at rate of 100cc/hr.

TPN per MST protocol

 

Other orders for John are:

 

Ventilator settings should be adjusted to maintain pCO2 between 30-35; keep O2 sats >95; suction prn

Hypothermia Blanket to maintain body temperature between 96-97 degrees Fahrenheit

Neuro checks, vital signs, PAWP readings and ICP readings q1h.

Urine output q2h. with specific gravity q2h.

Fluid intake to maintain blood osmolarity at 310mOsm--follow protocols for fluid resuscitation/restriction

Seizure Precautions

----------------------------------------------------------------------------------------------------------------

Questions:

 

1. What are the priorities of care for this patient during your shift today?

 

 

 

 

 

2. What is the rationale for the osmolarity level of the serum? What drugs are be used to aid the process?

 

 

3. Describe positions that are best for this patient to reduce ICP and positions and activities to avoid for a patient with increased ICP.

 

 

 

4. Explain the rationale for the hypothermia order.

 

 

5. Explain the rationale for the ventilator and O2 sat parameters. What would his blood gases look like?

 

 

6. What drugs are ordered for this patient that specifically reduce or control ICP? Give the action and rationale for each.

 

 

 

7. Give the rationale for the other drugs ordered.

 

 

 

 

8. In general, what category of drugs should be avoided with increased ICP and why?

 

 

When routinely suctioning John through his ET tube, you see "A" or plateau waves on the ICP monitor.

 

9. What would you do in this situation? Be prepared to give a rationale for your answer:

 

a. Stop suctioning immediately

b. Give Mannitol as ordered

c. Lower his head

d. Note the period of suctioning on the graphic readout from the ICP monitor

 

10. If John becomes markedly restless and begins thrashing about, what assessments would you make and what nursing interventions would be appropriate at this point?

 

 

 

As you do John's neuro check, he no longer responds to painful stimulus by withdrawing from the stimulus, but, instead, responds with a decorticate posture.

 

11. What area of his GCS would change, and what is now his total score?

 

12. What nursing assessments and interventions would be necessary now?

 

 

13. List other changes in John's signs (other than his ICP pressure readout) that would occur with increasing ICP.

 

 

John's level of consciousness continues to deteriorate and everytime you move him for care, he goes into decebrate posturing.

 

14. You report this to his neurosurgeon who may order what medical intervention at this point?

 

At 10:00 a.m., John's right pupil becomes dilated and fixed; this is a sudden change from fifteen minutes before. Doll's eyes are now absent.

15. What is the significance of these events, and what medical and nursing interventions are needed?

 Case Study #4: Spinal Cord Injury

 

Zack Wright, age 20, was brought into the ER after being pulled out of a local pond and resuscitated. He had unknowingly dived into shallow water and sustained a cervical spine injury with no movement or sensation below the level of the clavicles. At the scene, his GCS was 10, and he was intubated using the jaw thrust maneuver as he was having difficulty breathing and given 100% O2 via ambu bag. In route to the hospital, he was transported on a backboard with a cervical collar. He has no signs of other injuries. He is alert, appears very anxious, and is grimacing. PERRLA. The skin below the level of injury is very cool to touch. There is no spontaneous movement of his extremities. Vital signs are as follows: B/P=90/60, P=45, R=27 per ambu bag. An I.V. of Ringer's is running at 100cc/hr. via an antecubital site.

 

1. What assessments would be made in the ER and compared to the field assessments?

 

A--intubate, check blood gases and O2 sats, suction as needed; insert N/G tube to suction

B--give 100% O2 via ventilator; assess symmetry of chest movement and placement of ET tube

C--Place electrodes to monitor patient's cardiac status and start another line--preferably central-- to give fluids according to protocol for fluid resuscitation and to maintain B/P and urine output at ordered parameters; check vital signs frequently and treat for spinal shock; insert Foley

D--rule out head injury--continue to check GCS; check level of sensory and motor functioning and compare to paramedics report(cord edema can extend upward and worsen deficits)

E--expose to check for other injuries, but-----

F--keep patient warm since the level below his injury is cool with lack of sweating(poikilothermia) due to temporary dysruption of Autonomic Nervous System

G--Monitor vital signs & treat for pain which can occur at level of injury

H--continue to do frequent head to toe assessments for any deterioration and report to physician

I--inspect posterior surfaces by logrolling patient

Assessment as to whether the patient needs to go to surgery immediately--is there hemorrhage or CSF blockage at the site of injury or worsening neuro deficits with paralysis and sensory loss above the clavicles?

 

2. What state do the vital signs indicate?

Spinal shock--hypotension, bradycardia and altered respirations--fast or slow depending on level of injury;

Treat symptomatic bradycardia with Atropine as ordered

 

3. How does a spinal cord injury affect the autonomic nervous system?

Lack of temperature control and sweating below level of injury, no peristalsis, no bladder, bowel or sexual function, positional hypotension, no reflexes; some of these functions will return when spinal shock is over, but in an exaggerated or erratic manner.

 

4. What drugs would the patient be given in the ER and for what reasons?

High doses of Solu Medrol I.V. within 6-8hrs. after injury to reduce spinal cord edema and lessen level of nerve dysfunction; pt. would also be given pain control, possibly anxiolytics, Atropine for bradycardia, vasopressors for low B/P, Pepcid or similar drug for prevention of stress ulcer.

 

5. What other treatments/interventions are necessary at this point?

 

Labs? Xrays?

CBC, U/A, clotting profile, Blood chemistry, chest film, C-spine films to assess fracture- dislocation of vertebrae and if stable or unstable

 

Treatments?

Pt. would be placed in cervical traction with Gardner well tongs and weights on a special turning frame or Roto Rest Bed to immobilize him and prevent movement of injured spine; the bed would constantly rotate to prevent complications of immobility like pneumonia, pressure sores, DVT, etc. Later, a Halo device would be placed on the patient when he goes to rehab. so he is able to get out of bed to a wheelchair--Pin care would be done daily with cervical traction

SCD or Ted hose would be placed on the patient to prevent DVT; Lovenox would be started

Surgery may be done later if traction does not reduce fracture satisfactorily; patients with thoracic or lumbar vertebral fractures may need open reduction and spinal fusion at a later date to stabilize spinal column; they would be put in a body brace following this type of surgery.

 

Interventions?

TPN would be started for nutrition to meet his increased metabolic needs; P.T. for bracing and range of motion; chaplain to attend to spiritual needs

 

6. Zack's family arrives and asks if he is paralyzed. What do you say?

You would say that the extent of his motor loss cannot be fully determined at this time until the acute phase is over and spinal shock is over; give them emotional support without destroying hope or giving false reassurances.

 

7. What are other emotional and psychosocial concerns related to this type of injury?

Grieving for multiple losses: loss of freedom and mobility, sexual dysfunction, loss of other bodily functions like bladder and bowel control, loss of independence, often, loss of relationships or potential relationships(significant others often leave the injured person, or he becomes unattractive to potential mates). Pts. may become depressed and suicidal when faced with all these losses, and, since many may have drug or alcohol dependence, must be watched carefully.

  

8. How long will he be in the Intensive Care Unit?

Until spinal shock is resolved and any breathing or pulmonary issues are stabilized

 

 

After two weeks in ICU, Zack is transferred to a rehab unit. A trach was done as he needs help clearing his secretions, although he has diaphragmatic, spontaneous breathing at this point. The trach also protects the airway as he is on continuous tube feedings via Entreflex tube at 60cc./hr. He has some movement in his upper arms and feeling to the nipple line. He is in a Halo device, but his blood pressure drops significantly when his head is raised. New orders read:

1. Wean off trach--use Passy-Muir valve with instructions by speech therapist

These valves help patients relearn swallowing without aspiration; they can speak with the cuff of the trach tube deflated for if the trach tube is fenestrated.

2. Regular soft diet when tolerated

A diet high in protein, carbohydrates and fat calories is essential to prevent negative nitrogen balance, regain strength and bolster the immune system. Supplements will be given as necessary orally or by tube.

 

3. Intermittant Catheterization for residual every 4 hours; increase to every 6 hours as residuals decrease to <100cc

It is possible for a quad such as Zack who has return of autonomic reflexes that empty the bladder after spinal shock is over, to gain control over the pattern of urination through stimulation and intermittent catheterization. After the foley is discontinued, he will be catheterized for residual on a schedule such as every 4 hrs. Then, after his residual decreases, his cath routine will be advanced to every six hours, every eight hours, and so on. Before each cath, the patient is taught to "crede" or put pressure over the pubic bone or to stroke the thigh to get the bladder to empty spontaneously; the cath for residual is then carried out to completely empty the bladder. The patient's fluid intake must be considered in scheduling the intermittant cath routine, and it will be taught to the patient to do himself if he is able or to his caretakers with a clean technique once he goes home.

Patients with lower injuries in the lumbar area(paraplegics) will have no return of reflexes and their bladders will be flaccid(neurogenic bladder). They will have to have a suprapubic catheter or urinary diversion procedure such as an ileal conduit done. Foleys are not used long term in these patients since they are a major source of UTI and sepsis.

 

4. Start on Bowel Program three times per week

As with the bladder retraining program, it is possible in patients with return of autonomic reflexes to retrain the bowel to empty in response to digital stimulation and a Dulcolax suppository on a set schedule, usually q.o.d. or three times per week; caretakers must be taught to carry out this procedure since the quad cannot do this for himself. Patients have stated that this is the most embarrassing and difficult routine for them to accept from either their family caretakers or hired caretakers.

Again, patients with no return of these reflexes will have a flaccid bowel and will have to have enemas to evacuate the bowel. These are paraplegics, however, who can usually manage this routine themselves.

 

5. Reclining wheelchair with gradual adjustments to a sitting position as tolerated

Since the autonomic nervous system cannot react smoothly or rapidly to raise B/P in response to the upright position, quads must be acclimated to the upright position gradually through use of a reclining wheelchair. Their heads are gradually raised to a higher level over days or weeks so that their B/P will gradually adjust. Sometimes, vasopressors p.o. must be added to medication schedule to support B/P.

 

6. Continue ted hose and fit for abdominal binder when up in w/c

They also wear abdominal binders and compression stockings to aid in venous return on position change.

 

7. P.T. and O.T.

P.T. for strengthening, use of special wheelchairs, fitting for special w/c cushions to prevent pressure sores, teaching patients to do "weight shifts" to get pressure off their hips and buttocks periodically; O.T. for relearning as much as possible about ADLs, fitting special braces for upper extremities or suggesting home adaptations for independence. Rehab is a team approach with all disciplines involved in getting the patient to the highest level of functioning possible both independently and by training caretakers.

8. Percocet 1-2 tabs every six hours for pain prn

Many patients can become dependent on drugs, so they should be weaned as fast as possible to a nonnarcotic analgesic that is effective in controlling their pain. If patients have parasthesias that are painful, drugs such as Elavil or Neurontin that relieve painful neuropathies can be prescribed.

9. Lioresal (baclofen)10 mg p.o. tid

This is a skeletal muscle relaxant that lessens painful muscle spasms that interfere with daily functioning. Quads have spastic muscles that are prone to spasms; Paraplegics with flaccid muscle tone do not experience spasms.

10. Bactrim DS one tablet bid

Many patients are on prophylactic doses of urinary tract antiseptic drugs to prevent U.T.I.s which are common and can lead to renal dysfunction. Yearly, the patient should have a creatinine clearance test to evaluate renal function.

 

11. Ativan 1 mg q6h prn for anxiety

Again, a short term course is necessary, but counseling must be used when needed to lessen patient's dependence on this class of drugs. An antidepressant drug will be needed for clinical depression.

 

12. Vocational Rehab evaluation

Job retraining is necessary to get the patient back to being and perceiving himself as a productive member of society.

 

Zack seems to be progressing on the rehab unit; after a week he is on a routine of P.T. and O.T. bid, intermittant cath q6 hrs., bowel program q.o.d. on M-W-F. His head is now at 45 degrees with stable blood pressure and he is tolerating a soft diet with in between meal supplements. Pain is not a big problem. His affect is passive and he is cooperative, but quiet. His family are very overprotective at this point. One afternoon he calls you and states he has a terrible headache, looks flushed and is complaining of nasal stuffiness. His skin below the level of injury is cold with marked goose bumps.

 

1. What is happening to Zack and what assessments and interventions are necessary?

 

Zack is experiencing Autonomic Dysreflexia(A.D.)--a potentially life threatening situation; his B/P must be taken and monitored frequently, antihypertensives given as ordered to lower a B/P that is frequently over 200 systolic, his head elevated and bladder checked initially for distention(the most frequent cause of this hyperreflexia). M.D. must be notified. If the bladder and bowel are not the problem, the causes could range from severe muscle spasms to pressure over a bony prominence to an ingrown toenail. The cause must be found and relieved.

 

2. What other concerns need to be addressed?

Zack and his caretakers must be taught how to recognize and deal with "A.D.", since this can occur for years after the injury(patients with lesions above T-6).

Chronic Renal Failure

 

James Brubaker is a 55 year old man who was diagnosed two years ago with end-stage renal disease secondary to hypertension, necessitating treatment and hemodialysis. He is dialyzed at an outpatient clinic three times per week and is restricted to 1000 ml of fluid/day. His medications include:

 

Basaljel 2 Tabs PO tid

Iberet Folate 500mg. PO qam

Os-Cal 250mg. 2 tabs PO tid with meals

Nifedipine 30mg. tid

During the past week, Mr. Brubaker had been feeling ill and was not able to come for his dialysis appointments. In addition to his noncompliance in meeting his scheduled dialysis appointments, Mr. Brubaker omitted his medications on several occasions.

Today, Mr. Brubaker arrives in the Emergency Department extremely dyspneic. Initial vital signs reflect the following:

B/P 210/120

HR 108

Resp. 36

Temp. 37.8 C

Weight 178 lbs.

 

He is immediately transferred to the Medical ICU. Upon arrival, you assess Mr. Brubaker and find he is lethargic, slightly confused, nauseated, and vomiting. He complains of chest pain, described as moderate in intensity, diffusely located over the precordium and worsened by deep inspiration. Neck vein distention is present. He has rapid, shallow respirations at 36/minute. Auscultation of his lungs reveals crackles scattered throughout the lower 2/3 of his lung fields. A pericardial friction rub is auscultated in addition to an S3 gallop. Pitting peripheral edema is noted bilaterally in the lower extremities. The EKG monitor shows sinus tachycardia with occasional PVCs. The outpatient dialysis clinic states Mr. Brubaker's dry (ideal) weight is 160 lbs. Laboratory data reflect the following:
