DHA Exam Sample Questions: What to Expect and How to Practice

Understanding the DHA Exam Question Format

The DHA licensing exam is a computer-based test delivered through Prometric centres worldwide. It consists entirely of multiple-choice questions, each presenting a clinical scenario or knowledge-based stem followed by four or five answer options. You must select the single best answer from the choices provided.

Unlike exams that test isolated facts, the DHA exam emphasises clinical reasoning. Most questions use a vignette style that describes a patient presentation, relevant history, investigation results, and then asks you to identify the most appropriate diagnosis, next investigation, or management step. This format mirrors real clinical decision-making and rewards doctors who understand underlying principles.

The number of questions and time allotted varies by specialty. General practitioners typically face around 100 questions within a two-hour window, while specialist exams may have different distributions. There is no negative marking, so you should answer every question even if you are unsure.

Types of Questions You Will Encounter

DHA exam questions generally fall into several categories. Familiarising yourself with each type helps you approach them with confidence on exam day.

Clinical Vignette Questions

The majority of questions present a patient scenario with relevant history, examination findings, and investigation results. You are asked to identify the most likely diagnosis, the next best step in management, or the most appropriate investigation. Vignette questions typically run three to six lines long and require you to synthesise multiple pieces of clinical information. The key to mastering vignettes is learning to identify the critical clues embedded in the stem. Not every detail is equally important, and with practice you develop an instinct for spotting pivotal findings.

Single Best Answer Questions

Most DHA exam questions follow the single best answer format. You are given four or five options and must select the one that is most correct. In many cases more than one option may seem partially correct, but only one represents the best or most appropriate choice given the clinical context. This format tests your ability to prioritise and make sound clinical judgements.

Direct Knowledge Questions

A smaller proportion of the exam tests factual recall directly. These questions may ask about pharmacological mechanisms, normal laboratory values, anatomical relationships, or pathophysiology. While more straightforward than vignettes, they require a solid foundation across your specialty.

Image-Based Questions

Some questions include clinical images such as radiographs, ECGs, dermatological photographs, or histological slides. You will be asked to interpret the image and answer a related clinical question. It is wise to practise interpreting common imaging and clinical photographs relevant to your field.

Topics Most Frequently Tested

While the DHA exam covers the full breadth of your specialty, certain topics appear more frequently based on candidate reports:

• Pharmacology: Drug mechanisms, side effects, interactions, and contraindications are tested extensively. Know first-line treatments and their alternatives.
• Emergency and acute management: Recognising and managing emergencies, including resuscitation protocols and acute presentations.
• Common conditions: Diagnosis and management of high-prevalence conditions in your specialty.
• Investigations and interpretation: Knowing when to order specific tests and how to interpret results.
• Preventive medicine and screening: Guidelines for screening programmes, vaccinations, and preventive care.
• Ethics and patient safety: Informed consent, confidentiality, medical errors, and professional conduct.

Sample Question Walkthrough

While the DHA does not officially publish its question pool, the following examples illustrate the style and difficulty level you can expect.

Example 1: A 55-year-old male with a 20-year smoking history presents with progressive dyspnoea, productive cough, and barrel-shaped chest. Spirometry shows FEV1/FVC ratio of 0.62. What is the most likely diagnosis?

This question tests pattern recognition. The combination of smoking history, chronic respiratory symptoms, barrel chest, and obstructive spirometry points to COPD. The key is matching the clinical clues to the classic presentation rather than overthinking it.

Example 2: A 30-year-old woman presents with palpitations, weight loss, heat intolerance, and tremor. TSH is suppressed and free T4 is elevated. What is the most appropriate initial treatment?

Here you need to identify hyperthyroidism and know the first-line pharmacological approach. This tests both diagnostic and management skills in a single question.

Example 3: A 4-year-old child is brought to the emergency department with sudden-onset stridor, drooling, and high fever. He is sitting in a tripod position. What is the most important next step?

This question assesses emergency management. The presentation suggests epiglottitis, and the expected answer focuses on securing the airway rather than ordering investigations first. Understanding clinical priorities is essential for these acute-management questions.

Recommended Question Banks for DHA Exam Preparation

Investing in a reputable question bank is one of the most valuable decisions you can make for your preparation.

Dedicated DHA Preparation Platforms

Several online platforms offer question banks specifically designed for the DHA exam. These typically contain thousands of MCQs organised by specialty and topic, with detailed explanations for each answer. Look for platforms that are regularly updated, provide performance analytics, and offer questions that mirror the format and difficulty level of the actual exam.

International Medical Question Banks

Question banks designed for USMLE, PLAB, or MRCP can also be valuable. The clinical reasoning skills and medical knowledge they build are directly transferable. UWorld is frequently recommended by successful candidates for its high-quality explanations. While the content is not DHA-specific, the overlap in clinical knowledge is significant.

Prometric Practice Tests

Prometric offers a limited set of practice questions on their website. While the pool is small, these questions are the closest representation of the actual exam interface and format.

Textbook-Based Practice

Standard medical references and review books with end-of-chapter questions can reinforce foundational knowledge. While not substitutes for dedicated question practice, they help fill gaps in specific topic areas.

How to Practise Effectively

Simply reading through questions and answers is not enough. How you practise matters as much as how many questions you attempt.

Simulate exam conditions. Set a timer and work through blocks of questions without interruption. A good target is roughly 60 to 90 seconds per question. This builds stamina and helps you develop a sense of pacing. Many candidates run out of time because they did not practise under timed conditions.

Review every question thoroughly. After completing a practice block, go through each question regardless of whether you answered it correctly. Read the full explanation, understand why the correct answer is right, and learn why each incorrect option is wrong.

Track your weak areas. Most question banks provide performance analytics showing your accuracy by topic. Use this data to identify weak subjects and allocate more study time to them.

Space your practice over time. Spread your question practice over several weeks rather than cramming in the final days. Revisiting previously incorrect questions after a few days is particularly effective for long-term retention.

Simulate full exam conditions. At least two or three times during your preparation, take a full-length practice exam under realistic conditions. Sit at a desk, set a timer, avoid distractions, and complete the full question set without breaks beyond what the real exam allows.

Common Mistakes to Avoid

Candidates who struggle with the DHA exam often fall into predictable patterns. Being aware of these pitfalls can help you avoid them:

• Reading too quickly: Misreading the stem or overlooking a key detail is a frequent source of errors. Read carefully and identify exactly what is being asked before looking at the options.
• Changing answers without good reason: Your first instinct is often correct. Only change an answer if you have a clear, evidence-based reason to do so.
• Spending too long on difficult questions: Flag challenging questions and move on. Return to them after completing the easier ones.
• Ignoring explanations: Rushing through practice questions without reading explanations defeats the purpose of practice-based learning.
• Relying on a single resource: No single question bank covers every possible topic. Use multiple sources for comprehensive coverage.
