Assessed first in trauma patient - ANSWER - >Airway
(*)Degree of burn that is characterized by bone involvement -
ANSWER - >Fourth
Complications of head trauma - ANSWER - >Intracerebral
hematoma
Extradural hematoma
Brain abscess
Most common cause of laryngotracheal stenosis - ANSWER -
>Trauma
Intervention that can help prevent development of acute renal
failure - ANSWER - >Infusion of normal saline
A 26-year-old male is resuscitated with blood transfusion after
a motor vehicle collision that was complicated by a fractured
pelvis. A few hours later, the patient becomes febrile,
hypotensive with a normal CVP, and oliguric. Upon
examination, the patient is found to be bleeding from the NG
tube and IV sites. Which of the following is the most likely
diagnosis?
A. Hemorrhagic shock
,B. Acute adrenal insufficiency
C. Fat embolism syndrome
D. Transfusion reaction - ANSWER - >D. Transfusion reaction
Skin antiseptic - ANSWER - >-Ethanol 70% is an effective skin
antiseptic
-Acetic acid can be used to treat Gram- skin infections
-Salicylic acid is used to treat certain skin yeast infections
Class IV hemorrhage indicates what % blood loss - ANSWER -
>55%
How does shivering affect body temperature - ANSWER -
>Increases body temperature
Class III hemorrhage indicates what % of blood loss - ANSWER -
>35%
Management of a stable patient with kidney contusion -
ANSWER - >Observation
Associated with hypovolemic shock - ANSWER - >-Inadequate
tissue perfusion with resultant tissue hypoxia
-Blood shunting to vital organs
-Decreased circulating blood volume and decreased venous
return
-Low cardiac output
-Loss of less than 20% of the blood volume is usually without
symptom except for mild tachycardia
,-Patients become orthostatic with losses between 20 and 40%
-Shock is evidenced by tachycardia, hypotension, oliguria, flat
neck veins
The most effective method of monitoring the success of
resuscitation during CPR? - ANSWER - >Reactivity of pupils to
light
Used to ensure correct placement of endotracheal tube -
ANSWER - >-Ultrasound
-Bilateral breath sounds
-Sustained end-tidal CO2
Total body surface area involved in a burn in an adult to the
anterior chest and abdomen - ANSWER - >18%
What is often caused by carotid massage? - ANSWER -
>Bradycardia
Step in a patient diagnosed with tension pneumothorax -
ANSWER - >1. Needle decompression/ thoracotomy
2. Chest tube
True statements regarding diaphragmatic injuries - ANSWER -
>-Blunt diaphragmatic injuries are usually associated with
skeletal trauma
-Penetrating diaphragmatic injuries may be missed
-Repair of traumatic diaphragmatic injuries usually does not
require prosthetic material
, First priority in the treatment of an unconscious patient -
ANSWER - >Checking the pulse
A patient involved in a road accident is brought to the
emergency department in an unconscious state. On arrival, her
vitals show a temperature of 96.4 degrees Fahrenheit, a
respiration rate of 24 breaths per minute, a heart rate of 140
beats per minute, and a blood pressure of 80/40 mm Hg. She is
cold, shivering, and perspiring profusely. She has bilateral
reactive pupils but she does not respond to pain. On physical
examination, she has no obvious sign of external bleeding.
Which of the following cannot be the cause of hypotension in
this patient?
A. Pelvic fracture
B. Fracture of femur
C. Intracranial hemorrhage
D. Hemothorax - ANSWER - >C. Intracranial hemorrhage
A patient suffered a slash to his right neck. The wound is over
the mid-portion of the sternocleidomastoid. There is a large
hematoma and brisk bleeding when uncovered. He is stable.
What is the next step in management?
A. Get an angiogram
B. Close the wound in the ER
C. Take him to the operating room
D. CT scan to evaluate neck structure - ANSWER - >C. Take him
to the OR
