RASMUSSEN UNIVERSITY – NUR 2755 MULTIDIMENSIONAL CARE IV (MDC 4) FINAL EXAM – QUESTIONS AND ANSWERS | 2026/2027 LATEST UPDATE SECTION 1: EMERGENCY, TRAUMA, AND DISASTER NURSING Questions 1 – 10 1. Dur ing an initial trauma assessment, which action has the highest priority? A) Establish a patent airway while maintaining cervical - spine precautions B) Obtain a complete health history C) Assess the client's pain score D) Document the mechanism of injury Cor rect Answer: Establish a patent airway while maintaining cervical - spine precautions Rationale: Airway management is the first priority in the primary trauma survey because airway obstruction can rapidly cause hypoxia and death. Cervical - spine protection is maintained when trauma could have caused spinal injury. A detailed history, pain assessment, and documentation are important but occur after immediate threats to life are addressed. 2. At a mass - casualty incident, which triage category is represented by a patient who requires immediate lifesaving intervention? A) Green B) Red C) Yellow D) Black Correct Answer: Red Rationale: Red identifies patients with life - threatening but potentially survivable injuries who require immediate treatment. Yellow indicates d elayed treatment, green identifies those with minor injuries, and black is generally used for deceased or expectant patients according to the

triage system being used. Triage priorities are based on available resources and likelihood of benefit. 3. Which f inding most strongly suggests tension pneumothorax after blunt chest trauma? A) Bilateral crackles B) Productive cough C) Unilateral absent breath sounds with worsening respiratory distress D) Bradycardia with hypertension Correct Answer: Unilateral absent breath sounds with worsening respiratory distress Rationale: Tension pneumothorax causes accumulation of air under pressure, compressing the affected lung and potentially shifting mediastinal structures. Unilateral absent or markedly diminished breath sounds with acute respiratory distress is a major warning sign. Immediate recognition is essential because untreated tension physiology can rapidly impair venous return and cause cardiovascular collapse. 4. Which intervention is most appropriate when caring for a person experiencing heat stroke? A) Encourage oral alcohol - containing beverages B) Place the person in a warm room C) Delay cooling until laboratory results are available D) Move the person to a cool environment and initiate rapid cooling** Correct Answer: Move the person to a cool environment and initiate rapid cooling Rationale: Heat stroke is a medical emergency cha racterized by severe hyperthermia and neurologic dysfunction. Rapid cooling should begin immediately while emergency support is arranged. Waiting for laboratory confirmation delays lifesaving treatment. Alcohol is inappropriate because it can worsen dehydr ation and interfere with thermoregulation. 5. Which organization is particularly associated with a national network of community - based volunteers supporting public health preparedness? A) Medical Reserve Corps B) Federal Bureau of Investigation C) National Transportation Safety Board D) Occupational Safety and Health Administration

Correct Answer: Medical Reserve Corps Rationale: The Medical Reserve Corps is a national network of local groups that mobilizes volunteers with medical and public - health expertis e during emergencies and community health activities. Other organizations have important governmental or regulatory roles but are not primarily organized as community volunteer medical - response networks. Preparedness planning benefits from knowing the role of each agency. 6. A client with suspected spinal trauma is being moved from a vehicle. Which principle should guide the nursing response? A) Allow the client to twist toward the stretcher B) Maintain spinal alignment during movement C) Flex the client's neck to improve ventilation D) Sit the client upright before transport Correct Answer: Maintain spinal alignment during movement Rationale: Suspected spinal trauma requires protection of the spinal column during assessment and movement. Maintaining neutral alignment reduces the risk of converting an unstable injury into a more serious neurologic injury. Twisting, unnecessary flexion, or sitting the client upright can increase spinal movement and should be avoided unless specifically required for immediate a irway management. 7. Which assessment should be performed first during the primary survey of a critically injured client? A) Skin temperature B) Medication history C) Airway assessment D) Pain assessment Correct Answer: Airway assessment Rationale: The pri mary survey follows an organized approach beginning with airway assessment while protecting the cervical spine when indicated. Airway obstruction is an immediate threat to life and must be recognized before secondary assessments are performed. Medication h istory, pain, and skin findings remain important but do not supersede immediate airway evaluation. 8. Which disaster - preparedness recommendation is most appropriate for a household? A) Keep no emergency supplies because responders provide everything
