<h2>Chapter 10. Competency Cases</h2>
|
||
<p>This chapter can be used to assess competency.
|
||
Please read each case and based on the information
|
||
provided assign a triage acuity rating using ESI.</p>
|
||
<p>1. EMS arrives with a 76-year-old male found on
|
||
the bathroom floor. The family called 911 when
|
||
they heard a loud crash in the bathroom. The
|
||
patient was found in his underwear and the
|
||
toilet bowl was filled with maroon-colored
|
||
stool. Vital signs (VS) on arrival: blood pressure
|
||
(BP) 70/palp, heart rate (HR) 128, respiratory
|
||
(RR) 40. His family tells you he has a history of
|
||
atrial fibrillation and takes a "little blue pill to
|
||
thin his blood."</p>
|
||
<p>2. "The pediatrician sent us to the emergency
|
||
department (ED) because my son may have
|
||
appendicitis," reports the mother of a healthy
|
||
7-year-old. The child is sitting quietly next to
|
||
his mother holding an emesis basin. "He woke
|
||
me up this morning and told me his tummy
|
||
hurt. Usually he gets up and runs downstairs to
|
||
watch cartoons, but not today. The poor kid
|
||
vomited all over the doctor's office." VS:
|
||
temperature (T) 99.6° F, HR 94, RR 20, BP 88/62.</p>
|
||
<p>3. A 63-year-old cachectic male is brought in
|
||
from the local nursing home because his
|
||
feeding tube fell out again. The patient is
|
||
usually unresponsive. He has been in the
|
||
nursing home since he suffered a massive stroke
|
||
about 4 years ago.</p>
|
||
<p>4. You are trying to triage an 18-month-old whose
|
||
mother brought him in for vomiting. The
|
||
toddler is very active and trying to get off his
|
||
mother's lap. To distract him the mother hands
|
||
him a bottle of juice, which he immediately
|
||
begins sucking on. The child looks well
|
||
hydrated and is afebrile.</p>
|
||
<p>5. "I think I need a tetanus shot," a 29-year-old
|
||
female tells you. "I stepped on a rusty nail this
|
||
morning and I know I haven't had one for
|
||
years." No past medical history (PMH), no
|
||
known drug allergies (NKDA), no medications.</p>
|
||
<p>6. A 72-year-old female with obvious chronic
|
||
obstructive pulmonary disease (COPD) and
|
||
increased work of breathing is wheeled into
|
||
triage. Between breaths she tells you that she
|
||
"is having a hard time breathing and has had a
|
||
fever since yesterday." The SpO<sub>2</sub> monitor is
|
||
alarming and displaying a saturation of 84
|
||
percent.</p>
|
||
<p>7. "Why the hell don't you just leave me alone?,"
|
||
yells a 73-year-old disheveled male who was
|
||
brought to the ED by EMS. He was found
|
||
sitting on the curb drinking a bottle of vodka
|
||
with blood oozing from a 4-cm forehead
|
||
laceration. He is oriented to person, place, and
|
||
time and has a Glasgow Coma Scale (GCS) of
|
||
14.</p>
|
||
<p>8. EMS arrives in the ED with a 57-year-old female
|
||
with multiple sclerosis. She is bedridden and
|
||
her family provides care in the home. The
|
||
visiting nurse sent her to the ED because her
|
||
Foley catheter came out this morning. No other
|
||
complaints. Vital signs are within normal range,
|
||
currently on antibiotics for a UTI.</p>
|
||
<p>9. "How long am I going to have to wait before I
|
||
see the doctor?," asks a 27-year-old female with
|
||
a migraine. The patient is well known to you
|
||
and your department. She rates her pain as
|
||
20/10 and tells you that she has been like this
|
||
for 2 days. She vomited twice this morning.
|
||
PMH: migraines, no allergies, medications
|
||
include fioricet.</p>
|
||
<p>10. A young male ambulates into triage and tells
|
||
you that he has been shot. As he rolls up the
|
||
left leg of his shorts you notice two wounds. He
|
||
tells you that he heard three shots. He is alert
|
||
and responding appropriately to questions.
|
||
Initial VS: T 98.2° F, HR 78, RR 16, BP 118/80.</p>
|
||
<p>11. A 26-year-old female walks into the triage room
|
||
and tells you that she needs to go into detox
|
||
again. She has been clean for 18 months but
|
||
started using heroin again 2 weeks ago when
|
||
her boyfriend broke up with her. She had called
|
||
several detox centers but was having no luck
|
||
finding a bed. She denies suicidal or homicidal
|
||
ideation. She is calm and cooperative.</p>
|
||
<p>12. EMS radios in that they are in route with a 17-year-old with a single gun shot wound to the
|
||
left chest. On scene the patient was alert,
|
||
oriented and had a BP of 82/palp. Two large
|
||
bore IV's were immediately inserted. Two
|
||
minutes prior to arrival in the ED the patient's
|
||
HR was 130 and BP was 78/palp.</p>
|
||
<p>13. "My son needs a physical for camp," an
|
||
anxious mother tells you. "I called the clinic
|
||
but they can't see him for two weeks and camp
|
||
starts on Monday." Her son, a healthy 9-yearold
|
||
will be attending a summer day camp. </p>
|
||
<p>14. "Nurse, I have this pressure in my chest that
|
||
started about an hour ago. I was shoveling that
|
||
wet snow and I may have over done it," reports
|
||
an obese 52-year-old male. He tells you his pain
|
||
is 10 out of 10 and that he is nauseous and short
|
||
of breath. His skin is cool and clammy. VS: BP
|
||
86/50, HR 52 and irregular.</p>
|
||
<p>15. This patient is the restrained driver of an SUV
|
||
involved in a high-speed, multicar accident. Her
|
||
only complaint is right thigh pain. She has a
|
||
laceration on her left hand and an abrasion on
|
||
her left knee. VS: BP 110/74, HR 72, RR 16, no
|
||
medications, no allergies, no PMH.</p>
|
||
<p>16. "My doctor told me to come to the ED. I had a
|
||
gastric bypass 3 weeks ago and have been doing
|
||
fine but today I started vomiting and having this
|
||
belly pain." The patient, an obese 33-year-old
|
||
female rates her pain as 6/10. VS: BP 126/70, HR
|
||
76, RR 14, T 98° F.</p>
|
||
<p>17. "I was seen in the ED last night for my fractured
|
||
wrist. The bone doctor put this cast on and told
|
||
me to come back if I had any problems. As you
|
||
can see my hand is really swollen and the cast is
|
||
cutting into my fingers. The pain is just
|
||
unbearable." Circulation, sensation, and
|
||
movement are decreased.</p>
|
||
<p>18. A 42-year-old male presents to triage with a chief
|
||
complaint of "something in his right eye." He
|
||
was cutting tree limbs and thinks some sawdust
|
||
went into his eye. No PMH, no allergies, no
|
||
medications. On exam his right eye is reddened
|
||
and tearing.</p>
|
||
<p>19. An 88-year-old female is brought to the ED by
|
||
EMS. This morning she had an episode of slurred
|
||
speech and weakness of her left arm that lasted
|
||
about 45 minutes. She has a history of a previous
|
||
stroke and she takes an aspirin every day. She is
|
||
alert and oriented with clear speech and equal
|
||
hand grasps.</p>
|
||
<p>20. "It hurts so much when I urinate," reports an
|
||
otherwise healthy 25-year-old. She denies fever,
|
||
chills, abdominal pain, or vaginal discharge. VS:
|
||
T 98.2° F, HR 66, RR 14, BP 114/60.</p>
|
||
<p>21. "I think my son has swimmer's ear. He spends
|
||
half the day in the pool with his friends so I am
|
||
not surprised," the mother of a 10-year-old boy
|
||
tells you. The child has no complaints except
|
||
painful, itchy ears. VS: T 97° F, HR 88, RR 18, BP
|
||
100/68.</p>
|
||
<p>22. The medical helicopter is en route to your facility
|
||
with a 16-year-old male who was downhill skiing
|
||
and hit a tree. Bystanders report that he lost
|
||
control and hit his head. He was intubated at the
|
||
scene and remains unresponsive.</p>
|
||
<p>23. "I have this aching pain in my left leg," reports
|
||
an obese 52-year-old female. "The whole ride
|
||
home it just ached and ached." The patient tells
|
||
you that she has been sitting in a car for the last
|
||
two days. "We drove my daughter to college and
|
||
I thought it was the heat getting to me." She
|
||
denies any other complaints. VS: BP 148/90, HR
|
||
86, RR 16, T 98° F.</p>
|
||
<p>24. "My baby has a temperature of 101 rectally. I
|
||
called the pediatrician and he told me to come
|
||
here," reports the mother of a 3-week-old. The
|
||
baby is alert and sucking on a pacifier. Delivered
|
||
vaginally, no complications. "He's nursing fine. I
|
||
just wonder if he has the bug my other kids
|
||
had."</p>
|
||
<p>25. EMS arrives with a 45-year-old asthmatic who
|
||
has had a cold for a week. She started wheezing a
|
||
few days ago and then developed a cough and a
|
||
fever of 103. VS: T 101.6° F, HR 92, RR 24, BP
|
||
148/86. SpO<sub>2</sub> 97%.</p>
|
||
<p>26. "My right breast is so sore, my nipples are
|
||
cracked, and now I have a fever. Do you think I
|
||
will have to stop nursing my baby?," asks a
|
||
tearful 34-year-old female. She is 3 months post
|
||
partum and has recently returned to work part
|
||
time. VS: T 102.8° F, HR 90, RR 18, BP 108/60,

<h3>Answers and Discussion</h3>
|
||
<p>1. <strong>ESI level 1: requires immediate lifesaving
|
||
intervention.</strong> This 76-year-old patient
|
||
is in hemorrhagic shock from his GI bleed. His
|
||
blood pressure is 70, his heart rate is 128 and
|
||
his respiratory rate is 40, all indicating an
|
||
attempt to compensate for his blood loss. He
|
||
probably takes warfarin (Coumadin®) for his
|
||
atrial fibrillation. This patient needs immediate
|
||
IV access and the administration of fluid, blood,
|
||
and medications.</p>
|
||
<p>2. <strong>ESI level 3: two or more resources.</strong> The
|
||
child's pediatrician has already examined him
|
||
and referred the family to the emergency
|
||
department for further evaluation. At a
|
||
minimum he will need labs, an IV with fluid,
|
||
and other diagnostic tests in order to reach a
|
||
disposition.</p>
|
||
<p>3. <strong>ESI level 4: one resource.</strong> This patient will
|
||
be sent back to the nursing home after the
|
||
feeding tube is reinserted. There is no acute
|
||
change in his medical condition that warrants
|
||
any further evaluation. Yes, he is unresponsive
|
||
but that is the patient's baseline mental status
|
||
so he is not an ESI level 1.</p>
|
||
<p>4. <strong>ESI level 5: no resources.</strong> A physical exam
|
||
and providing the mother with reassurance and
|
||
education is what this 18-month-old will
|
||
require. His activity level is appropriate and he
|
||
is taking PO fluids.</p>
|
||
<p>5. <strong>ESI level 5: no resources.</strong> A tetanus
|
||
immunization does not count as a resource. The
|
||
patient will be seen by a physician or mid-level
|
||
provider, receive a tetanus immunization, and
|
||
discharge instructions. This patient will require
|
||
no resources.</p>
|
||
<p>6. <strong>ESI level 1: requires immediate lifesaving
|
||
intervention.</strong> Immediate aggressive
|
||
airway management is what this patient
|
||
requires. Her saturation is very low and she
|
||
appears to be tiring. The triage nurse does not
|
||
need the other vital signs in order to decide
|
||
that this patient needs immediate care.</p>
|
||
<p>7. <strong>ESI level 2: high-risk situation.</strong> The history
|
||
of events is unclear. How did this 73-year-old
|
||
gentleman get the laceration on his forehead?
|
||
Did he fall? Get hit? Because of his age,
|
||
presentation, and presence of alcohol he is at
|
||
risk for a number of complications.</p>
|
||
<p>8. <strong>ESI level 4: one resource.</strong> The patient has
|
||
been referred to the emergency department for
|
||
a new Foley catheter—one resource. There are
|
||
no other changes in her condition and she is
|
||
already on antibiotics for a UTI so no further
|
||
evaluation is needed.</p>
|
||
<p>9. <strong>ESI level 3: two or more resources.</strong> At a
|
||
minimum this patient will require an IV with
|
||
fluid, IV pain medication, and an antiemetic.
|
||
Although she rates her pain as 20/10 she should
|
||
not be assigned to ESI level 2. She has had the
|
||
pain for 2 days and the triage nurse can't justify
|
||
giving the last open bed to this patient. The
|
||
triage nurse will need to address this patient's
|
||
concerns about wait time.</p>
|
||
<p>10. <strong>ESI level 2: high-risk situation.</strong> This
|
||
patient has two obvious wounds but until he is
|
||
thoroughly examined in the trauma room you
|
||
can't rule out the possibility that he has
|
||
another GSW. The wounds on his thigh look
|
||
non-life-threatening but a bullet could have
|
||
nicked a blood vessel or other structure;
|
||
therefore, he meets ESI level-2 criteria. His vital
|
||
signs are within normal limits so he does not
|
||
meet ESI level 1 criteria.</p>
|
||
<p>11. <strong>ESI level 4: one resource.</strong> This patient is
|
||
seeking help finding a detoxification program
|
||
that will help her. She is not a danger to her self
|
||
or others. The social worker or psychiatric
|
||
counselor should be consulted to assist her.
|
||
Once a placement has been found she can be
|
||
discharged from the emergency department and
|
||
can get herself to the outpatient program. If
|
||
your social worker or psychiatric counselor
|
||
requires a urine toxicology or other lab work,
|
||
the patient will require 2 or more resources and
|
||
then meet ESI level-3 criteria.</p>
|
||
<p>12. <strong>ESI level 1: requires immediate lifesaving
|
||
interventions.</strong> The trauma team
|
||
needs to be in the trauma room and ready to
|
||
aggressively manage this 17-year-old with a
|
||
single GSW to the left chest. He will require
|
||
airway management, fluid resuscitation and,
|
||
depending on the injury, a chest tube or rapid
|
||
transport to the operating room.</p>
|
||
<p>13. <strong>ESI level 5: no resources.</strong> Because the mother
|
||
could not get an appointment with a primary
|
||
care physician, she brought her son to the
|
||
emergency department for a routine physical
|
||
exam. He will be examined and discharged.</p>
|
||
<p>14. <strong>ESI level 1: requires immediate life-saving
|
||
intervention.</strong> The history combined with the
|
||
signs and symptoms indicate that this patient is
|
||
probably having an MI. The "pressure" started
|
||
after shoveling wet snow and now he is
|
||
nauseous, short of breath and his skin is cool
|
||
and clammy. He needs immediate IV access, the
|
||
administration of medications, and external
|
||
pacing pads in place.</p>
|
||
<p>15. <strong>ESI level 2: high-risk situation.</strong> Based on
|
||
mechanism of injury this patient will need rapid
|
||
evaluation by the trauma team.</p>
|
||
<p>16. <strong>ESI level 3: two or more resources.</strong> She will
|
||
need two or more resources—laboratory tests,
|
||
intravenous fluid, medication for her nausea,
|
||
and probably a CT of her abdomen. This patient
|
||
will be in your emergency department an
|
||
extended period of time being evaluated. If her
|
||
pain was 10/10 and she was tachycardic the
|
||
patient would meet the ESI level-2 criteria.</p>
|
||
<p>17. <strong>ESI level 2: high-risk situation.</strong> Again, this
|
||
is a high-risk situation. The recent application of
|
||
a cast along with swelling of the hand and pain
|
||
that is unbearable justifies an ESI level-2 acuity
|
||
level. He may have compartment syndrome.</p>
|
||
<p>18. <strong>ESI level 4: one resource.</strong> The only resource
|
||
this patient will require is irrigation of his eyes.
|
||
A slit lamp exam is not considered a resource
|
||
but is part of the physical exam.</p>
|
||
<p>19. <strong>ESI level 2: high-risk situation.</strong> The
|
||
patient's history indicates that she may have had
|
||
a transient ischemic attack this morning. This
|
||
patient is high risk and it would not be safe for
|
||
her to sit in the waiting room for an extended
|
||
period of time.</p>
|
||
<p>20. <strong>ESI level 4: one resource.</strong> This patient will
|
||
require one resource—lab. A urinalysis and urine
|
||
culture will be sent and depending on your
|
||
institution, a urine pregnancy test. One or all of
|
||
these tests count as one resource.</p>
|
||
<p>21. <strong>ESI level 5: no resources.</strong> This child needs a
|
||
physical exam. Even if eardrops are administered
|
||
in the emergency department, this does not
|
||
count as a resource. The family will be sent
|
||
home with instructions and a prescription.</p>
|
||
<p>22. <strong>ESI level 1: requires immediate life-saving
|
||
intervention.</strong> Prehospital intubation is one of
|
||
the criteria for ESI level 1. This patient has
|
||
sustained a major head injury and will require
|
||
an immediate trauma team evaluation.</p>
|
||
<p>23. <strong>ESI level 3: two or more resources.</strong> At a
|
||
minimum she will require labs and noninvasive
|
||
vascular studies of her lower leg. She should be
|
||
placed in a wheelchair with her leg elevated and
|
||
instructed not to walk until the doctor has seen
|
||
her.</p>
|
||
<p>24. <strong>ESI level 2: high-risk situation.</strong> Any
|
||
neonate (day 1-28) with a fever over 100.4
|
||
rectally should be considered high risk regardless
|
||
of how they look at triage. At this age they have
|
||
limited ability to localize an infection.</p>
|
||
<p>25. <strong>ESI level 3: two or more resources.</strong> This
|
||
history sounds more like pneumonia. Because
|
||
the patient is not in acute respiratory distress he
|
||
or she doesn't meet ESI level-2 criteria. This
|
||
patient will require labs, a chest x-ray, and
|
||
perhaps IV antibiotics.</p>
|
||
<p>26. <strong>ESI level 3: two or more resources.</strong> At a
|
||
minimum she will require labs and IV
|
||
antibiotics.</p>
|
||
<p>27. <strong>ESI level 4: one resource.</strong> The laceration will
|
||
need to be sutured—one resource.</p>
|
||
<p>28. <strong>ESI level 3: two or more resources.</strong> At a
|
||
minimum this patient will require an x-ray of
|
||
his right arm and suturing of his chin laceration.</p>
|
||
<p>29. <strong>ESI level 5: no resources.</strong> The patient needs a
|
||
prescription refill and has no other medical
|
||
complaints. His blood pressure is controlled with
|
||
his current medication. If at triage his blood
|
||
pressure was 188/124, and he complained of a
|
||
headache then he would meet the criteria for a
|
||
high-risk situation and be assigned to ESI level 2.
|
||
If this patient's BP was elevated and the patient
|
||
had no complaints, he or she would still remain
|
||
an ESI level 5. The blood pressure would be
|
||
repeated and would most likely not be treated in
|
||
the ED or treated with PO medications.</p>
|
||
<p>30. <strong>ESI level 1: requires immediate life-saving
|
||
intervention.</strong> The patient's respiratory rate,
|
||
oxygen saturation, and inability to protect her
|
||
own airway indicate the need for immediate
|
||
endotracheal intubation.</p>
