NCCPA Emergency Medicine CAQ Examination Practice Test
Emergency medicine practice for the NCCPA Emergency Medicine CAQ Examination centers on rapid assessment and early treatment of acute illness and injury. The available questions sample decisions involving respiratory failure, dysrhythmia risks, seizures, sepsis, vision loss, wounds, and temperature-related emergencies, with attention to stabilizing patients while clarifying the cause.
Exam overview
About the NCCPA Emergency Medicine CAQ Examination Exam
Emergency care requires recognizing instability from vital signs, examination findings, and targeted tests, then prioritizing interventions without delaying time-sensitive treatment. Cases in the practice bank involve interpreting ECG changes and blood gases, screening for diabetic ketoacidosis, and identifying findings that point to acute conditions such as central retinal artery occlusion. Other scenarios test initial management of shock and pulmonary edema, choice of respiratory support for a tiring patient with hypercapnia, and medication selection during ongoing convulsions. Injury and environmental cases call for wound assessment, infection-risk planning, and safe rewarming decisions. These tasks reflect practical emergency reasoning: determine immediate threats, select an appropriate first action, and account for airway protection, hemodynamic status, comorbid illness, and potential complications.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A 67-year-old with sudden-onset dyspnea has oxygen saturation of 86% on room air. Examination reveals elevated jugular venous pressure, bilateral crackles, and pitting edema. Which initial treatment is most appropriate while evaluating the cause?
Show answer
Correct answer: AHypoxemia requires prompt supplemental oxygen, with monitoring and further assessment for acute heart failure or another cause. A large fluid bolus may worsen pulmonary congestion, and the other options do not address the immediate oxygenation problem.
A 63-year-old with chronic kidney disease reports fatigue and palpitations. ECG shows tall peaked T waves and widening of the QRS complex. Which medication should be administered first to stabilize the cardiac membrane while the cause is addressed?
Show answer
Correct answer: AThe ECG changes are concerning for severe hyperkalemia with cardiac membrane instability. Intravenous calcium stabilizes the myocardium rapidly but does not lower serum potassium, so potassium-shifting and removal measures are also needed.
A 54-year-old with a known seizure disorder has a witnessed generalized convulsion lasting six minutes. The patient remains actively convulsing on arrival. Which medication is generally the preferred initial pharmacologic treatment?
Show answer
Correct answer: AA convulsive seizure lasting five minutes or more is treated as convulsive status epilepticus. A rapidly acting benzodiazepine, such as intravenous lorazepam when IV access is available, is an appropriate initial medication, alongside airway and glucose assessment. Additional antiseizure therapy may be needed if seizure activity persists.
A 63-year-old with chronic obstructive pulmonary disease presents with worsening dyspnea and increased sputum production. Despite initial bronchodilator treatment, the patient is tiring and has an arterial blood gas showing pH 7.27 and PaCO2 68 mm Hg. The patient is awake and protecting the airway. Which respiratory support is generally appropriate to consider?
Show answer
Correct answer: AIn acute COPD exacerbation with respiratory acidosis and hypercapnia, noninvasive ventilation can improve ventilation and reduce the need for intubation when the patient can protect the airway and has no contraindication. Close reassessment is necessary, with escalation to invasive ventilation if clinical status worsens or noninvasive support fails.
A 22-year-old with type 1 diabetes has an insulin pump that stopped working overnight. The patient is alert, has glucose of 286 mg/dL, and has no vomiting or abdominal pain. Which test is most useful to screen for early diabetic ketoacidosis in this setting?
Show answer
Correct answer: AInsulin interruption can lead to ketone production before prominent symptoms develop. Measuring beta-hydroxybutyrate helps identify ketosis and is useful in assessing for evolving diabetic ketoacidosis; acid-base status and electrolytes are also evaluated when indicated.
A 76-year-old presents with new confusion and weakness. Temperature is 38.7°C, blood pressure is 86/52 mm Hg, and lactate is elevated. Urinalysis suggests infection. Which action should be part of the initial emergency management?
Show answer
Correct answer: ASuspected septic shock requires prompt resuscitation, early broad-spectrum antimicrobials, and assessment for infection source control. Cultures should be obtained before antibiotics when feasible, but not at the cost of a clinically important treatment delay.
A patient presents with sudden painless loss of vision in one eye. Funduscopic examination shows retinal whitening with a cherry-red spot. What is the most likely diagnosis?
Show answer
Correct answer: ACentral retinal artery occlusion typically causes sudden, painless monocular visual loss and may produce retinal pallor with a cherry-red spot. It is an ocular emergency requiring immediate specialist evaluation and assessment for associated vascular causes.
How to use this practice test
The free US Practice Tests bank contains 50 published questions for this exam. Each practice session presents up to 20 questions selected at random, with results shown after the session. Use the cases to identify which emergency findings or first-step decisions need further review.
Preparation tips
- For ECG cases, connect peaked T waves and QRS widening with severe hyperkalemia, and distinguish membrane stabilization from measures that lower serum potassium.
- Practice choosing respiratory support by assessing mental status, airway protection, work of breathing, and blood-gas evidence of hypercapnic acidosis.
- For suspected sepsis, rehearse recognizing shock from vital signs and lactate, then identifying time-sensitive initial actions and likely infection sources.
- Review emergency eye findings and distinguish sudden painless monocular vision loss with a cherry-red spot from other causes of acute visual loss.
- For wounds and environmental exposure, consider shoe-sole puncture infection risks, wound exploration and closure preparation, and rewarming needs based on hypothermia severity.
