Introduction

How to use this book

Clinical skills exams—sometimes called “objective structured clinical examinations” or OSCEs—are a rite of passage for all physicians in training. These exams include the MCCQE II and the Certification Examination in Family Medicine in Canada, and equivalent exams in other countries such as the USMLE Step 2 CS in the United States.

This book is designed to help you prepare for these exams. Although simply reading through the cases in this book will be useful, the best way to study for a clinical skills exam is to practice. Groups of 3 or 4 work best, assigned to the following roles:

– Candidate: reads aloud a case from the list of cases at the back of the book. Reading aloud ensures that everyone knows the boundaries of the task. The candidate should then “perform the task” by formulating questions to ask the patient, or describing other procedures such as physical examinations or investigations, as required.

– Examiner: uses the notes for the case to formulate one or two pertinent questions to ask the candidate and to remind the candidate of any crucial steps they may have missed.

– Observers: help debrief the task. We recommend that observers pay particular attention to skills such as: communicating clearly and respectfully; setting appropriate priorities; engaging issues of medical ethics as needed; and resolving clinical situations that require the expertise of specialists.

Work through all the cases in the book in this way, changing roles each time.

Each case has time limit—either 5 minutes or 10 minutes—in keeping with the protocols for the Canadian clinical skills exams. In some instances, in an effort to be comprehensive, the cases set up more tasks than a candidate could realistically accomplish within the assigned time. It is still useful, however, to set a timer or stopwatch for the assigned time, to get a feel for “how long you have.”

Take the time to work through all the cases thoroughly and thoughtfully, so start at least a few months in advance of the exam. This will allow you to use each case to its fullest—exploring different issues and questions that each could contain—and allow you to gain some level of comfort and confidence in the face of an otherwise stressful exam.

We have tried to avoid the use of jargon as much as possible. However, in the interests of space we have used a number of abbreviations, and we have listed these in the abbreviations section at the back of the book.

Medicine is famous for the number of mnemonics that students have developed over the years to remember certain aspects of history or management, and we have given these as appropriate throughout the book. Memorizing the most important of these should prove useful in situations where you need to think on your feet.

No book of this nature can ever be “complete.” We encourage you to draw from other sources in preparing for your clinical skills exam. In particular, you should be familiar with advanced lifesaving (ALS) protocols, and should review general textbooks in each of the areas in which you will be tested.

Approach to clinical stations at the exam

At the exam, you will encounter clinical stations. Each will have a simulated patient and an examiner. Some stations—those about trauma or cardiac emergencies, for example—may also have a “helper” present such as a nurse.

In general you should ignore the examiner unless they specifically address you.

You should be dressed professionally and you should act professionally. Introduce yourself to the simulated patient and shake their hand if appropriate. If you are asked to perform a physical examination, ask the simulated patient for permission before you start.

Remember that, in a clinical examination like you are facing, the cases you are given to work through will be diagnosable. The examiners will not be trying to trick you. Therefore, if you are handed an ECG to interpret, the diagnosis will likely be straightforward. Furthermore, if you are asked to manage the patient based on the ECG findings, the diagnosis will likely be something that has an advanced life-saving algorithm like an acute myocardial infarction or ventricular fibrillation. Likewise, a lateral C-spine X-ray will be far more likely to show a fracture-dislocation than a rare congenital malformation; a chest X-ray will more likely show a tension pneumothorax than nonspecific findings. You get the picture.

Because the clinical stations aim to test you on relatively common, diagnosable entities, at least some of the examiners’ questions are predictable. While this book does not contain all possible scenarios, experience has shown that many stations at the exam will be similar to the scenarios described here.

Unfamiliar scenarios

If you are presented with an unfamiliar scenario, don’t panic! Even if you are completely lost, you can still often salvage a station by introducing yourself, acting professionally, performing a history of the presenting complaint, and reviewing symptoms, medications, allergies, family history, and social history. In doing so, you will likely uncover the information that will help you regroup and still do well. If all else fails, ask open-ended questions, such as “Is there anything else you want to tell me?” If you completely flop on a station, regroup and carry on for the next one.

A note on the scenarios

This book unpacks 133 cases organized around the major themes of the Canadian MCCQE II. These themes are logical and the cases are typical—they are on-point preparation for any clinical skills exam. Note that the cases are representative of cases encountered on the Canadian MCCQE II and the Certification Examination in Family Medicine in Canada, but are not direct “remembrances.”

General approaches to history taking

History taking is key to many stations in clinical exams, and so to many cases in this book. We present some general strategies for history taking below.

In all cases, it’s useful to begin history taking with a quick explanation to the patient, such as “I’m going to ask some questions to get some background information on your health and medical history.”

Generally, you should begin with questions about the present illness and then move to past medical history.

HISTORY OF PRESENT ILLNESS

Why are you here today?
When did this symptom/problem start?

FOR PAIN

What is the location?
What kind of pain is it (sharp, dull, throbbing)?
How bad is the pain on a scale of 1 (low) to 10 (high)?
Where does the pain radiate?
When did the pain begin?
What makes the pain worse? What makes it better?
Do you have other symptoms with the pain (e.g., nausea)?

PAST MEDICAL HISTORY

Ask questions to ascertain details about the following areas (mnemonic: PAM HUGS FOSS).

Previous presence of the symptom, previous conditions
Allergies
Medicines
Hospitalizations
Urinary changes
Gastrointestinal complains
Sleep pattern
Family history
OB/GYN history
Sexual history
Social history

Note that we describe specific aspects of this sequence in more detail below.

ALLERGY AND MEDICINES HISTORY

What prescription medication do you take? How long and what dosage?
What over-the-counter medications or preparations do you take? How long and what dosage?
Do you have any drug allergies? What was the reaction?

Is there a family history of diabetes?
Is there a family history of high blood pressure?
Is there a family history of heart problems?
Is there a family history of seizures?
Do other diseases run in your family?

OBSTETRICAL/GYNECOLOGICAL HISTORY

It’s wise to approach obstetrical and gynecological history taking with particular sensitivity: patients may feel embarrassed.

GYNECOLOGICAL HISTORY

How old were you when you had your first period? (Or—as appropriate—when your breasts began to develop?)
How long is your usual cycle? How many days of bleeding are usual for you?
