NUR 445 EXAM 4 STUDY GUIDE & PRACTICE TEST 2026/2027
1 of 29
Term
The nurse is conducting triage under mass casualty conditions and
assigns which tag to the patient who is experiencing hypovolemic
shock as a result of a penetrating wound?
1. Red
2. Black
3. Green
4. Yellow
Give this one a go later!
3. The patient who is walking, has abrasions, and follows commands appropriately
, Rationale: The patient who is walking, has abrasions, and follows commands
appropriately.
1. Red
Rationale: The nurse uses a red tag for a patient who has injuries that are an
immediate threat to life, such as hypovolemic shock, during mass casualty
conditions.
2. Hospital Regulatory Agency
Rationale: The decision to evacuate a hospital should be based on the ability of the
hospital to meet the medical needs of the patients. Hospitals should have in place
plans for either a full or partial evacuation, and those plans should be consistent
with regulatory requirements.
4. Level D
Rationale: Level D PPE consists of a surgical gown, mask, and gloves. It provides no
additional protection for respiratory or splash hazards and only minimal protection
for nuisance contamination.

Term
The nurse recognizes that which disorder increases the patient's risk for
obstructive shock?
1. Dissecting aneurysm
2. Cardiac tamponade
, 3. Gastrointestinal bleeding
4. Severe heart failure
Give this one a go later!
2. Cardiac tamponade
Rationale: Obstructive shock is caused by a mechanical barrier to ventricular
filling or ventricular emptying (increased afterload), causing decreased
cardiac output. Examples of disorders resulting in impaired filling include
cardiac tamponade and tension pneumothorax. An example of a disorder
resulting in increased afterload is severe valvular disease.
2. Absent bowel sounds
Rationale: The progressive stage of shock is manifested by lethargy/coma,
hypotension, dysrhythmias, anuria, absent bowel sounds, severe metabolic acidosis,
respiratory acidosis, cold extremities, and weak or absent pulses
3. Spinal cord injury
Rationale: Distributive shock is the result of disease states that cause poor vascular
tone and vasodilation, resulting in increased vascular capacity and venous pooling.
Neurogenic shock is due to a loss of vasomotor tone. There is a loss of stimulation
from the sympathetic nervous system, resulting in vessel walls relaxing and dilating.
Venous return is decreased, and the patient is hypotensive with a decreased cardiac
output. Neurogenic shock can be caused by an injury to the brain, general or spinal
anesthesia, or spinal cord injury.
2. Level B
Rationale: Level B provides the greatest level of respiratory protection but a lower
level of skin protection than level A. It provides splash protection against liquids
