Question 1
The dietician arrives to evaluate patients on the burn unit. Which patient should the nurse
recommend that the dietician see FIRST?
- 15% TBSA and a transferrin of 300 mg/dL
- 25% TBSA and a hemoglobin A1C of 5.2%
- 10% TBSA and a prealbumin of 20 mg/dL
- 19% TBSA and albumin of 4.0 g/dL
CORRECT ANSWER
- 25% TBSA and a hemoglobin A1C of 5.2%
Comments: Larger burns, burns with >20% TBSA, lead to a hypermetabolic state which
substantially increases the body's need for calories and protein. The registered dietician
provides crucial support to help ensure the patient is meeting their nutritional needs to
promote optimal wound healing. All labs are within normal limits._____Reference: Burn

Question 2
5)
A previously healthy, independent elderly patient with a 22% TBSA scald burn is now
agitated, disoriented to time and place and is attempting to pull out intravenous catheters
and their feeding tube. After reorienting the patient and ensuring their safety, what
pharmacological management should the nurse anticipate?
-Acetaminophen (Tylenol)
-Zolpidem (Ambien)
-Haloperidol (Haldol)

,-Lorazepam (Ativan)
CORRECT ANSWER
-Acetaminophen (Tylenol)
Comments: In addition to early mobilization and promoting sleep hygiene, managing pain
is critical in minimizing the incidence of delirium. The use of benzodiazepines has been
proven to worsen delirium as well -Lorazepam (Ativan)as Ambien and Haldol, especially in
the older population._____Reference: Burn Nursing: Injury Prevention to Rehabilitation
and After Care, 1st Ed. (2023), p. 488
Question 3
During the initial phase of burn injury, what is the PRIMARY concern regarding a patient's
airway?
-bronchospasm
-swelling of the lower airway
- sloughing of the oropharynx
- swelling of the upper airway
CORRECT ANSWER
swelling of the upper airway
Airway concerns in burn patients can lead to death within minutes. Upper airway swelling
can lead to total obstruction of the airway. Airway edema can occur with mucosal injury
and fluid shifts with a large volume resuscitation._____Reference: Jeschke, M.G., Gauglitz,

Question 4
2
@https://www.stuvia.com/user/thestudyvault
,A 45 year-old male sustained a 9% TBSA partial thickness burn to the right forearm, right
shoulder and upper back by contact with a 1200 volt electrical wire. The burns are non-
circumferential. The patient is awake and alert and appears to be answering questions
appropriately. What criteria would qualify this patient for immediate consultation with a
burn center?
-Location of burn
-Patient's age
-Type of burn
-TBSA burned
CORRECT ANSWER
-Type of burn
Criteria for referral include electrical injury. Burn Center referral include greater than 10%
TBSA, burns involving the face, hands, feet, genitalia, perineum or major joints. Age is
primarily considered for the care of children not adults._____Reference: Advanced Burn
Life Support Course Provider Manual (2023), p. 18
Question 5
A nurse is caring for a patient following tangential excision and skin grafting for a 10%
TBSA burn to both arms and hands. The donor site dressings on the thighs display three
areas of frank blood, each approximately 3cm in diameter. The vital signs are as follows:

36.1 C
Question 7

, The patient is moaning. Estimated blood loss in surgery was 150mL. What is the nurse's
FIRST action?
-Assess the patient for pain.
-Remove the dressing and assess the site.
-Perform a 12 lead ECG.
-Administer a unit of packed red blood cells.
CORRECT ANSWER
-Assess the patient for pain.
This patient is moaning, and vital signs are elevated. This indicates pain, which is common
following burn excision and grafting. A blood transfusion is not indicated at this time, as
EBL was low and small areas of bleeding on donor sites is to be expected postoperatively. A
12 lead ECG is not indicated, as pain is the cause of this patient's elevated HR. Removing
the dressing would disturb the wound bed and cause more bleeding. This is not indicated
at this time. _____Reference: Burn Nursing: Injury Prevention to Rehabilitation and After
Care, 1st Ed. (2023), p. 83
Question 8
An adult patient is admitted to the burn center following an explosion that occurred while
the patient was welding the inside of a fuel transport tank. Assessment reveals burns to
the right leg and right hand as well as a right femur fracture. EMS intubated the patient on
scene due to shortness of breath. The nurse recognizes the MOST likely need for
intubation was due to:
-extensive burns.
-severe pain.
-barotrauma
-inhalation injury.
