Chapter 10. Competency Cases

This chapter can be used to assess competency. Two sets of 25 case studies have been included. The cases are divided into two sets to allow flexibility in ESI competency evaluation. For example, Set A can be used for initial assessment and Set B can be used for remedial or follow-up assessment. Both sets contain realistic patient scenarios that a triage nurse would encounter in any emergency department. Please read each case and, based on the information provided, assign a triage acuity rating using ESI. Answers to all cases follow after Set B.

Set A Competency Cases—Answers

1. ESI level 3: Two or more resources. From the patient's history, he will require labs and IV fluid replacement—two resources.
2. ESI level 3: Two or more resources. It looks as though this patient has a displaced fracture and will need a closed reduction prior to casting or splinting. At a minimum, he needs x-rays and an orthopedic consult. This patient may also require procedural sedation. However, there are already two or more resources, so it is not necessary to be overly concerned about counting resources beyond two.
3. ESI level 1: Requires immediate lifesaving intervention; possible aggressive fluid resuscitation.
4. ESI level 2: Severe pain or distress. This patient needs aggressive pain management with IV medications. There is nothing the triage nurse can do to decrease the patient's pain level. The answer to "Would you give your last open bed to this patient?" should be yes.
5. ESI level 3: Two or more resources. The patient is presenting with signs and symptoms of another kidney stone. At a minimum, he will need a urinalysis and CT scan. If his pain increases, he may need IV pain medication. At a minimum, two resources are required. If the pain level was 7/10 or greater and the triage nurse could not manage the pain at triage, the patient could meet level-2 criteria.
6. ESI level 2: High risk. Rashes are difficult to triage, but the presence of petechiae is always a high-risk situation. Even if the patient looks good, it is important to recognize that petechia can be a symptom of a life-threatening infection, meningococcemia.
7. ESI level 4 or 5: This case is an example of variations in practice around the country. Many emergency departments would examine the child and then attempt to reduce the dislocation of the radial head without an x-ray. Others may x-ray the child's arm, which is considered one ESI resource. Relocation is not considered a resource.
8. ESI level 2: High-risk. An asthmatic with a prior history of intubation is a high-risk situation. This patient is in respiratory distress as evidenced, by her respiratory rate, oxygen saturation, and work of breathing. She does not meet the criteria for ESI level 1, requires immediate lifesaving intervention.
9. ESI level 2: High risk. This patient is demonstrating respiratory distress with his increased respiratory rate and decreased oxygen saturation. Symptoms are caused by compression of the superior vena cava from the tumor. It is difficult for blood to return to the heart, causing edema of the face and arms.
10. ESI level 1: Requires immediate lifesaving intervention. Depending on the exact location penetrating neck trauma can cause significant injury to underlying structures. Based on the presenting vital signs, immediate actions to address airway, breathing, and circulation are required. Intubation might be necessary due to the large neck hematoma, which may expand.
11. ESI level 5: No resources. This healthy-sounding 11-year-old will be examined by a physician and then discharged home with appropriate instructions and a prescription if indicated.
12. ESI level 2: High risk. This patient has an elevated respiratory rate and heart rate. The symptoms of polydipsia and polyuria are two classic signs of diabetic ketoacidosis.
13. ESI level 3: Two or more resources. This 19-month-old is dehydrated and will require a minimum of two resources: labs and IV fluids. In addition the physician may order an IV antiemetic.
14. ESI level 3: Two or more resources. This patient probably has a fractured hip and will need an x-ray, IV pain medication, and an orthopedic consult. If the reason for a fall in the elderly is unclear, the patient should be assigned ESI level 2 to rule out a cardiac or neurological event.
15. ESI level 5: No resources. Following a physical exam, this baby will be discharged to home. Prior to leaving, the mother needs to be taught techniques to keep the baby's nares clear of mucus.
16. ESI level 2: High risk. An elderly patient with increasing confusion and a fever needs to be evaluated for an infection. UTIs and pneumonia need to be ruled out. This patient may be septic and requires rapid evaluation and treatment.
17. ESI level 2: New-onset confusion, lethargy, or disorientation. The mother of this 4-year-old knows her child and has probably been through this situation before. A child with a ventriculo-peritoneal shunt with a change in level of consciousness and a headache is thought to have a blocked shunt until proven otherwise and may be experiencing increased intracranial pressure.
18. ESI level 1: Requires immediate lifesaving intervention. This patient is experiencing another cardiac event that requires immediate treatment. His vital signs and skin perfusion are suggestive of cardiogenic shock, and the patient may require fluid resuscitation or vasopressors to treat hypotension.
19. ESI level 3: Two or more resources. The patient is presenting with signs and symptoms of an infection. At a minimum, he will require labs, an x-ray, an orthopedic consult, and IV antibiotics.
20. ESI level 3: Two or more resources. An x-ray is needed to confirm placement in rectum. Then IV sedation and analgesia may be used to enable the physician to remove the foreign body in the ED, or he may be admitted for surgery. In this situation, two or more resources are required.
21. ESI level 3: Two or more resources. This elderly patient may have pneumonia. Labs and a chest x-ray are required, in addition to IV antibiotics. If vital signs are outside the accepted parameters, they may be considered high risk and meet ESI level-2 criteria.
22. ESI level 2: High risk. The mechanism of injury represents a high-risk situation. His left upper-quadrant pain could be due to a splenic rupture or injury. He may also have a fractured femur, another source of volume loss. This patient's vital signs are stable, so there is no need for immediate lifesaving intervention, but he is at risk for hemorrhagic shock due to volume loss.
23. ESI level 4: One resource. It is unknown whether the patient was bitten by the bat because they were sleeping, so postexposure prophylaxis will be initiated. One resource—an intramuscular medication.
24. ESI level 1: The patient is presenting with signs of shock, hypotension tachycardia, and tachypnea. He has a history of HTN and is presenting with signs and symptoms that could be suggestive of a dissecting aortic abdominal aneurysm. On arrival in the emergency department, he will require immediate lifesaving interventions such as immediate IV access, aggressive fluid resuscitation, and perhaps blood prior to surgery.
25. ESI level 5: No resources. Following a physical exam, this patient will be discharged to home with a prescription and appropriate discharge instructions. No resources are required.

Set B Competency Cases—Answers

1. ESI level 3: Two or more resources. Based on the mechanism of injury, this patient will require an x-ray of his clavicle and suturing of his arm laceration. In addition, he may need a tetanus booster, but that does not count as a resource. If the mechanism of injury was higher, the patient could meet ESI level-2 criteria, high risk. The patient's pain rating is 8/10, but the triage nurse can intervene by applying a sling and providing ice to decrease the pain and swelling.
2. ESI level 2: Severe pain or distress. This patient needs to be taken to a safe, quiet room within the emergency department. Her medical, emotional, and legal needs must be addressed in a timely manner.
3. ESI level 5: No resources. Following a physical exam, this young man will be discharged to home with a prescription and appropriate discharge instructions.
4. ESI level 5: No resources. This patient was instructed to come back to the emergency department for a wound check. He will be examined and discharged to home. No resources are required. A point-of-care finger stick glucose is indicated, but this is not a resource. If the patient came back with a fever or increasing pain and redness, then his ESI level would reflect the additional resources he would require.
5. ESI level 1: Requires immediate lifesaving interventions. From the history, it sounds like the hockey player experienced a disruption in the electrical activity in his heart due to the blow to the chest from the hockey puck. He will require immediate lifesaving interventions to address airway, breathing, and circulation. This patient is intubated, which meets criteria for lifesaving interventions.
6. ESI level 3: Two or more resources. This patient has a history of asthma that is not responding to her rescue inhaler. In addition, she has a fever. At a minimum, she will need two resources: hand-held nebulizer treatments and a chest x-ray.
7. ESI level 4: One resource. This patient will need an ear irrigation to flush it out.
8. ESI level 5: No resources. This patient will require a physical exam then a tetanus booster, which is not considered a resource.
9. ESI level 2: High risk. This patient is exhibiting signs of central retinal artery occlusion, which represents an acute threat to loss of vision. Rapid evaluation is necessary.
10. ESI level 4: One resource. To rule out a fracture, this patient will require an x-ray, one resource. The application of a splint and crutch walking instructions are not counted as resources. This patient does not meet the criteria for ESI level 2 for pain because nursing can immediately initiate interventions to address her pain.
11. ESI level 2: High risk. An overdose is a clear high-risk situation. This patient needs to be seen immediately, and interventions to prevent liver damage must be initiated. At the same time she needs to be placed in a safe, secure environment and monitored closely to prevent harm to herself.
12. ESI level 3: Two or more resources. The patient is presenting with a colitis flare. She will need labs and possibly an IV and a CT of the abdomen, especially in light of her presentation with normal vital signs. Two resources.
13. ESI level 4: One resource. This young man presents with a mechanism of injury suggestive of a boxer's fracture. An x-ray is indicated to rule out a fracture,—one resource.
14. ESI level 2: High risk. Sickle cell disease requires immediate medical attention because of the severity of the patient's pain, which is caused by the sickle cells occluding small and sometimes large blood vessels. Rapid analgesic management will help prevent the crisis from progressing to the point where hospitalization will be unavoidable.
15. ESI level 3: Two or more resources. This patient will need lab tests and lower-extremity vascular studies to rule out a deep vein thrombosis.
16. ESI level 3: Two or more resources. This patient will need to be seen by surgery or GI and her PEG tube reinserted—two resources.
17. ESI level 2: High-risk situation. This patient is a danger to herself and needs to be placed in a safe environment with a constant observer.
18. ESI level 5: No resources. The patient will need a history and physical exam and then will be discharged to home with a prescription. An oral dose of his blood pressure medication does not count as a resource.
19. ESI level 5: No resources. A tetanus booster is not a resource, and neither is cleaning and dressing abrasions.
20. ESI level 1: Requires immediate lifesaving intervention. The trauma team needs to be in the trauma room and ready to aggressively manage this 21-year-old with a single gunshot wound 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.
21. ESI level 3: Two or more resources. This patient probably has a cellulitis of the hand and will require labs and IV antibiotics. Starting a saline lock is not a resource, but IV antibiotics are a resource.
22. ESI level 2: High-risk situation. An overdose is a high-risk situation, and wellbutrin overdoses are prone to seizures, hallucinations, and irregular heart rhythms. This patient is suicidal and also needs to be monitored closely for safety.
23. ESI level 2: High-risk situation. This 48- year-old male is probably showing signs of alcohol withdrawal, a high-risk situation. He is restless, tremulous and tachycardic. In addition he is hypertensive. He is not safe to wait in the waiting room, and should be given your last open bed.
24. ESI level 3: Two or more resources. Abdominal pain, loss of appetite, and nausea in a 10-year-old who has not had a bowel movement in several days is probably due to constipation. He will need two or more resources—labs, maybe an x-ray, maybe a surgery consult, maybe an enema—but at least two resources.
25. ESI level 1: Requires immediate lifesaving intervention. This young asthmatic is tiring out and will need immediate lifesaving intervention that will require at a minimum a nurse and physician at the bedside immediately. The decision may be to continue the respiratory treatments and try IV steroids, IV magnesium, and heliox immediately. She may also require rapid sequence intubation.
