A 25-year-old man presents to the ED complaining of pleuritic chest pain and shortness of breath. He is afebrile, has no other symptoms, takes no medications and has never had any surgery. You wonder whether a clinical decision rule such as the (PERC could help exclude PE without the need for D-dimer testing.

A 72 year old man with a history of hypertension presents to the emergency department with acute onset of sharp chest pain. There are no acute ischemic ECG changes. Thoracic aortic dissection is certainly one of many diagnoses in the differential. You wonder if there is a clinical risk score than can be calculated to categorize the risk of having an aortic dissection.

A 12-year-old boy presents to the emergency department with a history of limp and decreased range of movement at his right hip. You suspect that he may have a slipped capital femoral epiphysis. You wonder whether plain film radiograpy or ultrasound sonography would be a more sensitive diagnostic modality for slipped capital femoral epiphysis.

A 67-year-old man is brought to the emergency department. He is cold, clammy and confused. He is also hypotensive and an ECG shows that he has had an AMI with ST elevation. While your colleagues prepare some vasopressors you speak to the cardiologist on call. He suggests getting the patient to the cardiac cath lab to put in an IABP. You wonder whether there is any evidence to support this course of action?

During a long resuscitation in the emergency department, you have to repeatedly remind the members of staff performing chest compressions to keep up a good rate. You recall that during previous cardiac arrests, the quality and rate of external cardiac compressions differs between operators. You wonder if a metronome could help providers by defining a set rate and so improve cardiopulmonary resuscitation (CPR) quality.

A 50-year-old man presents to the emergency department having been woken from sleep by his implanted cardioverter-defibrillator (ICD) firing; it has fired twice more since that time. He is in sinus rhythm and has no acute signs or symptoms. A recent angiogram showed no significant coronary artery disease (CAD). You speak to the Cardiology Registrar who advises that troponin levels should be checked. You wonder if there is any evidence for this and, further, how you might interpret the result.

A 1-year-old child presents to the emergency department in cardiac arrest. His mother does not speak English; through an interpreter, you learn she gave an unknown cold medication, but she is not sure if she gave the correct amount because she did not understand the English instructions. You wonder whether the cause of the cardiac arrest is more likely to be the underlying condition or over the counter medication.

A 55-year-old man with a history of prior abdominal surgery presents to the emergency department with nausea, abdominal distension and absence of bowel movements for 2 days. He is not vomiting. An abdominal X-ray shows signs of small bowel obstruction. You know that there are considerable safety issues in passing and confirming the correct placement of nasogastric tubes (NGT). You wonder if there is any literature supporting these of NGT in such cases, or whether the risks outweigh the benefits.

A 41-year-old woman with a history of intravenous drug abuse and hepatitis C is brought to the emergency department with altered mental status. She is somnolent but opens her eyes to loud verbal stimuli and localises pain. She is breathing spontaneously with good effort. She has evidence of track marks along her upper extremities. The nursing staff are having difficulty obtaining intravenous access. The respiratory technician happens to be walking by the room and asks you if there is anything he can do to help—he has heard of patients having nebulised naloxone when in this state. You wonder if he is right.

You are working a shift in an Emergency Department (ED), and you receive a call from prehospital providers requesting advice in management of a violent and incoherent patient with strength far in excess of expected for his size. This seems consistent with reports you have read of Excited Delirium Syndrome (EXDS). You recall reports of sudden death in these patients and wonder if you can prevent this.

You work in the emergency department as a consultant and your rota currently does not include night working. Nationally it has been recognised that there is a deficit of senior decision makers in emergency departments at night and inevitably it is suggested that care would be safer and more effective if (work-shy) senior emergency physicians stepped off the golf course and into the gap to work shifts. You have heard that this will increase your chances of a heart attack and shorten your life but wonder whether this is just union propaganda or hard actuarial fact.

A 75-year-old man with a known history of chronic obstructive pulmonary disease and type 2 respiratory failure presents to the emergency department with a 2 day history of productive cough and shortness of breath. There are no signs of cardiovascular shock. He refuses radial arterial blood gas sampling due to pain and discomfort from previous attempts and asks whether an alternative site for sampling can be used. You ask a colleague who recommends the brachial artery—a vessel you have avoided in the past having been told that distal ischaemia can result. You wonder whether your worries are evidence based.

A 10-year-old child is to be discharged from the paediatric emergency department after presenting in anaphylactic shock. In accordance with National Institute for Health and Clinical Excellence guidelines you prescribe an adrenaline autoinjector (AAI) and teach him and his mother the six-step technique for use using a training device. They both seem happy but you wonder if they will still remember the technique in the future or in an emergency situation?

A 45 years old man came to emergency department with sever epigastric pain and vomiting, he was tachycardic and hypotensive, immediate fluid resuscitation stabilized his hemodynamic status. Labs revealed high lipase and amylase suggesting acute pancreatitis; he was kept NPO on intravenous fluid and was treated with analgesics and anti-emetics. The case was referred to gastroenterologist for admission who on further discussion, was enquiring why antibiotic was not started in ED for a better outcomes? This stimulated my thought, if starting prophylactic antibiotics in case of acute pancreatitis improve the outcome in term of morbidity and mortality.

A 56 years old male, who is a smoker and known case of hypertension not on any medication as well as known case of severe Gastro-eosophageal reflux disease attended emergency department with sever tearing pain retrosternally radiating to back. Examination did not reveal anything significant, and he remains heamodynamically stable through-out . Serial ECG and troponine are negative. Chest x-ray does not show any widening of mediastinum or any other evidence suggestive of Aortic dissection. Still the possibility of aortic dissection was considered due to the nature of the pain hence; D- dimer was send and the result was negative. I was wondering is it sensitive enough to rule out aortic dissection?

An 87 years old man presents to the Emergency Department with acute onset of central abdominal pain.. The pain is mild and was relieved by simple analgesia. you noticed that he had a temp of 37.8 and whit cell count of 13,000 with elevated neutrophil count. examination revealed no tenderness, guarding or rigidity and there was no masses but bowel sounds were sluggish. You wonder if this patient can go home or need to be admitted for observation and if so why?. The patient's medical history included hyperlipaedemia, hypertension, and that he is a smoking 10 cigarettes every day for the past 55 years..
