A 10-year-old child is being treated by the emergency department staff. He or she has a normal systolic blood pressure, a rapid heartbeat, somewhat delayed capillary refill, and chilly, pale complexion. How much shock is the child most likely experiencing?
The impact of shock on systolic blood pressure is frequently used to describe shock severity. The shock is referred to as ""compensated"" when the compensatory mechanisms are active and keep the systolic blood pressure constant. Shock is categorized as ""hypotensive"" (formerly called ""decompensated"") when the mechanisms can no longer support the blood pressure.

A 24-year-old guy with gunshot wounds to his abdomen and left groin area has been transported by emergency medical services to the emergency department. His heart rate is 120 beats per minute, and his blood pressure is 84/52. His skin is pale, cold, and diaphoretic. The procedure for which the nurse should get ready is:
The young man's symptoms and gunshot wounds suggest that he has suffered from hypovolemia as a result of severe blood loss. A quick intravenous infusion of a crystalloid solution is used to treat hypovolemia.
The following are all indications of respiratory failure, WITH THE EXCEPTION
Not respiratory failure, although respiratory discomfort is indicated by nasal flaring and retractions. You can recognize respiratory failure by the following symptoms: diminished air movement, central and peripheral cyanosis, decreased level of consciousness, and decreased breathing effort with late bradypnea.
All of the typical assessments listed below can be used to quickly assess a child's neurological condition, WITH THE EXCEPTION OF:
The Epworth Scale is a drowsiness test that is not typically evaluated as part of a child's neurological examination. The neural state of a child can be assessed using the AVPU and Glasgow Coma measures. It's important to assess the size and reaction of the pupil. (zolpidem)
A patient who is experiencing respiratory distress is receiving positive pressure ventilation through an ET tube from you. Aside from: All of the following are signs that you are breathing too quickly.
Aspiration, stomach insufflation, and tension pneumothorax are latrogenic consequences of hyperventilation with an ET tube. Waveform capnography readings that are rising are a sign of effective CPR.
A patient who is in cardiogenic shock is under your care. You are aware that one of this condition's likely causes is:
The most common cause of cardiogenic shock is congestive heart failure. Cardiogenic shock can also be brought on by acute myocardial infarction and other cardiac disorders. Hypovolemic shock can be brought on by dehydration. Injury to the spinal cord may result in neurogenic shock. Septic shock can result from infection.
The optimum method to confirm and maintain tracheal tube position, when available, is described by the American Heart Association ACLS guidelines as:
To establish and maintain ET tube position, the AHA advises using clinical evaluation and continuous waveform capnography.

📝 How many questions are on the CEN exam?
The CEN exam has 175 multiple-choice items. Only 150 are scored; the other 25 are unscored pretest items that BCEN is trialing for future exams, and they are not marked, so treat every question as if it counts.
START CEN PRACTICE TEST🎯 What score do you need to pass the CEN exam?
You must answer 106 of the 150 scored items correctly, which is about 71%. BCEN states the passing score is not curved; it depends only on your own performance on the exam.
START CEN PRACTICE TEST⏱️ How long is the CEN exam?
Total seat time is 180 minutes (3 hours) for 175 items, roughly one minute per question. Five practice questions at the start familiarize you with the testing software before the exam timer begins.
START CEN PRACTICE TEST🔁 How soon can you retake the CEN exam if you fail?
BCEN requires a 90-day waiting period before you retake the CEN exam. A discounted retest fee applies if you reapply within one year of your first attempt, and Test Assurance buyers get a no-fee second attempt.
START CEN PRACTICE TEST❤️ ST elevation in leads II, III and aVF means which artery is blocked?
ST elevation in leads II, III and aVF indicates an inferior wall MI. The right coronary artery is the most common culprit, so watch for bradycardia and heart blocks, and obtain right-sided leads to check for right ventricular involvement.
START CEN CARDIO PRACTICE TEST🫀 What is Beck's triad on the CEN exam?
Beck's triad is hypotension, jugular venous distension and muffled heart sounds. It points to cardiac tamponade, a common CEN trauma scenario after penetrating chest injury, treated by relieving the fluid around the heart (pericardiocentesis or surgery).
START CEN TRAUMA PRACTICE TEST🧠 What is Cushing's triad and what does it signal?
Cushing's triad is hypertension with a widening pulse pressure, bradycardia and irregular respirations. It is a late sign of rising intracranial pressure and impending brain herniation, so it calls for immediate escalation of care.
START CEN NEURO PRACTICE TEST🔥 How do you calculate burn fluids with the Parkland formula?
Parkland formula: 4 mL x body weight (kg) x %TBSA burned of lactated Ringer's over 24 hours. Give half in the first 8 hours from the time of the burn, not from arrival, and the rest over the next 16 hours.
START CEN TRAUMA PRACTICE TEST🫁 What is the priority for a suspected tension pneumothorax?
Tension pneumothorax is a clinical diagnosis: absent breath sounds on one side, hypotension, distended neck veins and late tracheal deviation. Do not wait for a chest X-ray; perform immediate needle decompression, followed by chest tube placement.
START CEN RESPIRATORY PRACTICE TEST🚑 What is ESI triage and what does ESI level 1 mean?
The Emergency Severity Index (ESI) is a five-level ED triage system. ESI level 1 means the patient needs an immediate life-saving intervention, such as for cardiac arrest, while levels 4 and 5 need one or no resources.

Try these questions from our free CEN - Certified Emergency Nurse practice tests. The correct answer and an explanation follow each question.
A patient has a zone II penetrating neck injury with active bleeding. Which is the priority intervention?
- A. CT angiography of the neck
- B. Immediate surgical exploration
- C. Direct pressure and airway management
- D. Diagnostic angiography and embolization
Answer: C. Direct pressure and airway management
For any penetrating neck injury with active hemorrhage, direct pressure to control bleeding combined with airway management is the immediate priority before any imaging or surgical planning.
A patient arrives after a motor vehicle accident. He is hypotensive with a distended abdomen and a seatbelt sign. What is the most appropriate rapid assessment?
- A. CT abdomen/pelvis with contrast
- B. Diagnostic peritoneal lavage (DPL)
- C. Focused Assessment with Sonography for Trauma (FAST)
- D. Plain abdominal X-ray
Answer: C. Focused Assessment with Sonography for Trauma (FAST)
FAST exam rapidly detects free intra-abdominal fluid (blood) at the bedside and can immediately guide surgical decision-making in a hemodynamically unstable patient.
A patient presents with crushing chest pain, diaphoresis, and ST elevation in leads II, III, and aVF. Which coronary artery is most likely occluded?
- A. Left anterior descending
- B. Right coronary artery
- C. Left circumflex artery
- D. Left main coronary artery
Answer: B. Right coronary artery
ST elevation in leads II, III, and aVF indicates an inferior MI, which is most commonly caused by occlusion of the right coronary artery.
A patient with carbon monoxide poisoning has a carboxyhemoglobin level of 30% and is confused. Which oxygen delivery is the treatment priority?
- A. Nasal cannula at 4 L/min
- B. 100% oxygen via non-rebreather mask
- C. Hyperbaric oxygen therapy
- D. Intubation with 40% FiO2
Answer: B. 100% oxygen via non-rebreather mask
100% oxygen via non-rebreather mask is the immediate treatment for CO poisoning; it reduces CO half-life from ~5 hours on room air to ~60–90 minutes.
