CTRN Sample Questions and Answers

Question 1.

A transport nurse is preparing to transfer a mechanically ventilated patient with severe ARDS from a community hospital to a tertiary care center. During the pre-transport assessment, the patient’s oxygen saturation is 92% on FiO₂ 0.80 with PEEP of 14 cm H₂O. Which intervention is the highest priority before departure?

A. Reduce PEEP to minimize barotrauma during transport

B. Verify ventilator settings, oxygen supply, battery life, and availability of backup airway equipment

C. Administer a diuretic before transport

D. Change the patient to a transport ventilator after leaving the hospital

Correct Answer: B

Detailed Explanation.

Transport significantly increases patient risk because access to additional equipment and personnel is limited once the vehicle departs. The transport nurse should ensure the transport ventilator is programmed correctly, confirm adequate oxygen reserves for the anticipated trip plus contingency time, verify battery capacity, and prepare backup airway equipment before departure. Reducing PEEP without clinical indication may worsen oxygenation, while delaying ventilator transition until after departure increases the chance of instability. Diuretics should only be administered if clinically indicated and do not replace thorough transport preparation. Safe transport begins with meticulous equipment verification and contingency planning.

Question 2.

A trauma patient becomes hypotensive shortly after being loaded into the ground transport ambulance following a motor vehicle collision. Breath sounds are absent on the left side, and jugular veins become increasingly distended. Which condition should the transport nurse suspect first?

A. Neurogenic shock

B. Pulmonary embolism

C. Tension pneumothorax

D. Acute myocardial infarction

Correct Answer: C

Detailed Explanation:

The combination of hypotension, unilateral absent breath sounds, and jugular venous distention strongly suggests tension pneumothorax. This life-threatening condition causes increasing intrathoracic pressure that impairs venous return and cardiac output. Immediate decompression is required before transport continues. Neurogenic shock generally presents with hypotension and bradycardia without unilateral absent breath sounds. Pulmonary embolism develops differently and myocardial infarction does not explain the absent breath sounds. Transport clinicians must rapidly recognize evolving obstructive shock because deterioration can occur within minutes inside the transport environment.

Question 3.

A patient receiving norepinephrine develops a sudden drop in blood pressure during transport. The infusion pump appears to be functioning normally. What should the transport nurse assess first?

A. Serum lactate level

B. IV catheter patency and infusion tubing integrity

C. Blood glucose concentration

D. Urinary output

Correct Answer: B

Detailed Explanation:

Mechanical causes are common during transport. Vibration, patient movement, and repositioning can dislodge intravenous catheters or kink tubing, interrupting vasopressor delivery. Before escalating medication doses, the transport nurse should immediately verify IV patency, inspect tubing connections, confirm pump function, and assess for infiltration or disconnection. Laboratory studies and urine output are useful later but do not address an immediately reversible cause of hypotension. Rapid troubleshooting prevents prolonged interruption of life-sustaining medications and reflects sound transport nursing practice.

Question 4.

A transport nurse is caring for a patient with septic shock receiving norepinephrine through a central venous catheter. During transport, the arterial waveform suddenly becomes dampened, and the MAP falls from 72 mmHg to 48 mmHg. The patient remains awake, warm, and has a strong radial pulse. What should the nurse do first?

A. Verify the arterial line system for transducer position, tubing kinks, air bubbles, and perform a square-wave test before escalating vasopressor therapy.

B. Double the norepinephrine infusion immediately.

C. Begin chest compressions.

D. Administer atropine.

Correct Answer: A

Detailed Explanation:

A sudden change in an arterial waveform without corresponding clinical deterioration should prompt evaluation of the monitoring system before altering treatment. A dampened waveform may result from air bubbles, blood clots, loose connections, transducer displacement, or catheter kinking. The CTRN should always compare monitor readings with the patient’s clinical presentation. Escalating vasopressors based on inaccurate arterial pressure readings may expose the patient to unnecessary complications.

Question 5.

A 67-year-old man with septic shock secondary to pneumonia is being transported to a tertiary ICU. He is intubated and receiving:

• Norepinephrine: 0.35 mcg/kg/min
• Vasopressin: 0.03 units/min
• FiO₂: 50%
• PEEP: 8 cm H₂O

Thirty minutes into transport, his MAP falls from 72 mmHg to 55 mmHg. The arterial waveform becomes dampened, but the patient is awake, follows commands, has warm extremities, and a palpable radial pulse.

What should the CTRN do FIRST?

A. Assess the arterial line system before increasing vasopressors.

B. Double the norepinephrine dose immediately.

C. Administer atropine.

D. Stop the vasopressin infusion.

Correct Answer: A

Detailed Explanation:

This scenario tests whether the candidate treats the patient or the monitor. The patient’s clinical assessment does not match the arterial pressure reading. A dampened waveform may result from catheter kinking, clotting, air bubbles, loose tubing, or an improperly leveled transducer. The transport nurse should first verify the accuracy of the arterial line before escalating vasoactive therapy. Increasing vasopressors based on inaccurate monitoring could produce dangerous hypertension and tissue ischemia. The CTRN exam frequently tests integration of equipment troubleshooting with clinical assessment.

Question 6.

A 58-year-old woman with ARDS is being transported on mechanical ventilation.

Current settings:

• Volume Control
• TV 420 mL
• RR 22
• PEEP 12
• FiO₂ 70%

Suddenly:

• SpO₂ falls from 95% to 82%
• Peak pressure rises from 32 to 46 cm H₂O
• Plateau pressure remains 27 cm H₂O
• Diffuse bilateral wheezing is heard.

Which intervention is MOST appropriate?

A. Treat bronchospasm with bronchodilators.

B. Needle decompress the chest.

C. Increase tidal volume.

D. Remove all PEEP.

Correct Answer: A

Detailed Explanation:

High peak pressure with a normal plateau pressure indicates increased airway resistance rather than reduced lung compliance. Diffuse wheezing strongly supports bronchospasm. The nurse should administer bronchodilators, suction if indicated, reassess airway resistance, and monitor ventilator waveforms. Recognizing ventilator mechanics is heavily emphasized on the CTRN examination.

Question 7.

A patient with traumatic brain injury develops systolic blood pressure of 82 mmHg during transport. What is the transport nurse’s priority?

A. Lower blood pressure to reduce intracranial pressure

B. Maintain cerebral perfusion by promptly correcting hypotension

C. Delay treatment until arrival

D. Hyperventilate the patient continuously

Correct Answer: B

Detailed Explanation:

Hypotension significantly worsens secondary brain injury by reducing cerebral perfusion pressure. Maintaining adequate systemic blood pressure is a critical transport goal in traumatic brain injury. Continuous hyperventilation is no longer recommended except temporarily for impending herniation because it can reduce cerebral blood flow. Immediate treatment focuses on restoring perfusion through fluids, vasopressors when indicated, and correction of reversible causes. Preventing hypotension is one of the strongest predictors of improved neurological outcomes.

Question 8.

While transporting a patient receiving continuous propofol sedation, the nurse notices progressive hypotension. Which medication effect most likely explains this finding?

A. Increased systemic vascular resistance

B. Peripheral vasodilation and myocardial depression

C. Bronchodilation

D. Increased preload

Correct Answer: B

Detailed Explanation:

Propofol commonly causes hypotension by producing vasodilation and reducing myocardial contractility, particularly in critically ill or volume-depleted patients. During transport, careful hemodynamic monitoring is essential because changes may occur rapidly with movement or ongoing illness. The transport nurse should assess volume status, sedation depth, infusion rate, and overall clinical condition before adjusting therapy. Understanding medication pharmacodynamics allows prompt recognition of expected adverse effects.

Question 9.

Which transport scenario carries the greatest risk for accidental endotracheal tube dislodgement?

A. Patient remaining stationary in the ICU

B. Moving the patient between stretcher and ambulance cot

C. Routine pulse oximetry monitoring

D. Electronic chart documentation

Correct Answer: B

Detailed Explanation:

Patient transfers between beds, stretchers, and transport cots create the highest risk for accidental airway dislodgement because multiple caregivers are repositioning equipment simultaneously. The airway should be continuously protected with one provider specifically assigned to stabilize the endotracheal tube during every movement. Equipment should be secured before transport begins. Careful coordination reduces preventable airway emergencies in confined transport environments.

Question 10.

A patient being transported after thrombolytic therapy for ischemic stroke suddenly develops severe headache and declining consciousness. What should the nurse suspect?

A. Migraine headache

B. Intracranial hemorrhage

C. Hypoglycemia

D. Anxiety attack

Correct Answer: B

Detailed Explanation:

Sudden neurological deterioration after thrombolytic administration raises immediate concern for intracranial hemorrhage, one of the most serious complications of fibrinolytic therapy. The transport nurse should rapidly perform a neurological assessment, communicate findings to medical control, maintain airway and blood pressure goals, and expedite transport to definitive care. Delayed recognition may significantly worsen neurological outcomes. Continuous reassessment remains essential throughout transport.

Question 11.

A transport nurse is transferring a patient with septic shock who is receiving norepinephrine through a central venous catheter. Approximately 15 minutes into transport, the patient’s mean arterial pressure suddenly falls from 72 mmHg to 48 mmHg. The infusion pump indicates that the medication is running normally. Which action should the nurse perform first?

A. Increase the norepinephrine infusion rate immediately.

B. Verify the integrity of the central line, infusion tubing, medication connections, and catheter patency before adjusting medications.

C. Administer a large dose of intravenous furosemide.

D. Disconnect the infusion pump and restart it after arrival.

Correct Answer: B

Detailed Explanation:

One of the most common causes of sudden hemodynamic deterioration during transport is interruption of medication delivery due to tubing disconnection, catheter occlusion, loose luer-lock connections, or accidental line tension. The infusion pump may continue operating despite medication not reaching the patient. Before increasing vasopressor doses, the CTRN should rapidly trace the medication from the pump to the vascular access site, inspect all connections, evaluate catheter patency, and confirm that the medication is actually being delivered. This systematic troubleshooting approach is a hallmark of expert transport practice.

Question 12.

A patient with septic shock remains hypotensive despite aggressive fluid resuscitation. Which hemodynamic finding suggests persistent distributive shock?

A. Elevated systemic vascular resistance

B. Warm extremities with persistent hypotension

C. Bradycardia with hypertension

D. Narrow pulse pressure caused by hypovolemia alone

Correct Answer: B

Detailed Explanation:

Early distributive septic shock is characterized by peripheral vasodilation, resulting in warm extremities despite persistent hypotension. Systemic vascular resistance is typically reduced rather than elevated. Transport nurses should continue vasopressor therapy, reassess perfusion frequently, monitor lactate trends when available, and ensure adequate oxygen delivery throughout transport. Early recognition guides appropriate pharmacologic support and improves patient outcomes.

Question 13.

A transport nurse is preparing to transfer a patient with an open chest following emergency cardiac surgery. Shortly after loading the patient, blood pressure falls from 96/60 mmHg to 68/40 mmHg, central venous pressure rises, and chest tube drainage abruptly stops. What is the most likely cause?

A. Cardiac tamponade caused by chest tube obstruction

B. Acute myocardial infarction

C. Pulmonary edema

D. Hypoglycemia

Correct Answer: A

Detailed Explanation:

Sudden cessation of mediastinal chest tube drainage accompanied by hypotension and rising central venous pressure strongly suggests cardiac tamponade. Blood accumulating within the mediastinum compresses the heart, reducing ventricular filling and cardiac output. The CTRN should recognize this classic postoperative emergency, assess tube patency, notify the cardiothoracic surgeon immediately, and expedite transport. This scenario represents a true transport emergency because delayed intervention can rapidly result in pulseless electrical activity.

Question 14.

Crew resource management primarily aims to improve patient outcomes by:

A. Eliminating all transport risks

B. Enhancing teamwork, communication, and shared situational awareness

C. Allowing only the team leader to make decisions

D. Reducing documentation requirements

Correct Answer: B

Detailed Explanation:

Crew resource management emphasizes effective communication, leadership, mutual support, workload distribution, and situational awareness among transport team members. These principles reduce preventable errors, particularly during high-stress situations requiring rapid clinical decisions. Collaborative teamwork allows early identification of problems and promotes safer patient care. Effective crew coordination is a foundational competency in modern transport nursing.

Question 15.

During transport, a patient receiving blood transfusion develops fever, dyspnea, hypotension, and back pain. What is the transport nurse’s immediate priority?

A. Slow the transfusion rate

B. Stop the transfusion immediately while maintaining IV access with normal saline

C. Administer acetaminophen and continue transfusion

D. Increase the transfusion rate

Correct Answer: B

Detailed Explanation:

These findings strongly suggest an acute transfusion reaction. The priority intervention is immediate discontinuation of the blood product while maintaining intravenous access with normal saline using new tubing according to institutional protocol. The transport nurse should support airway, breathing, and circulation, notify medical control and the receiving facility, closely monitor vital signs, and prepare for advanced interventions if shock develops. Continuing or merely slowing the transfusion may worsen the reaction. Prompt recognition and intervention significantly reduce morbidity and mortality associated with severe transfusion complications.
