window after symptom onset. ✔️✔️
What are the key components of the ABCDE approach in trauma care?
The ABCDE approach includes: A (Airway with cervical spine protection), B (Breathing and ventilation), C
(Circulation with hemorrhage control), D (Disability—neurological status), and E (Exposure and
environmental control). ✔️✔️
What is the most common cause of hypovolemic shock in trauma patients?
,The most common cause is blood loss due to hemorrhage from injuries such as lacerations, fractures, or
internal bleeding. ✔️✔️
What is the priority in the management of a patient with severe heatstroke?

tourniquet above the bleeding site if pressure alone is ineffective. ✔️✔️
What is the main purpose of administering intravenous fluids to a patient in shock?
The main purpose is to restore intravascular volume, improve tissue perfusion, and maintain blood
pressure. ✔️✔️
What assessment is most important when caring for a patient after a cardiac arrest?
The most important assessment is to monitor for signs of return of spontaneous circulation (ROSC) and
ensure adequate oxygenation, ventilation, and perfusion. ✔️✔️
How would you handle a patient experiencing a severe allergic reaction who is also hypotensive?
Administer intramuscular epinephrine immediately, followed by IV fluids to address hypotension, and
monitor for improvement in symptoms while preparing for further interventions as necessary. ✔️✔️
What is the priority action for a patient with suspected carbon monoxide poisoning?
, The priority is to administer 100% oxygen to displace carbon monoxide from hemoglobin and improve
oxygen delivery to tissues. ✔️✔️
How do you manage a patient with an open pneumothorax?
Cover the wound with an airtight dressing, tape it on three sides to allow air to escape but not re-enter,
and provide supplemental oxygen to the patient. ✔️✔️
What is the first-line management for a patient with anaphylaxis?
The first-line management is the immediate administration of intramuscular epinephrine, followed by
airway management and oxygen support. ✔️✔️
What is the most critical factor in determining the prognosis of a patient with a traumatic brain injury?
The most critical factor is the Glasgow Coma Scale (GCS) score, which helps to assess the depth of coma
and the level of consciousness. ✔️✔️
What are the signs of compartment syndrome following a limb injury?
Signs include severe pain, pallor, paresthesia, paralysis, and pulselessness in the affected limb. ✔️✔️
What should you assess for in a patient with suspected opioid overdose?
Assess for respiratory depression, pinpoint pupils, altered level of consciousness, and hypotension.
✔️✔️
What is the appropriate nursing action for a patient with a large contusion to the abdomen and signs of
