Mixed Deck — All OSCE Topics Flashcards

Before applying a sterile dressing in an OSCE, what is the most critical infection-prevention step?

Answer: Performing hand hygiene and applying sterile/non-touch technique throughout the procedure

Hand hygiene (before and after) combined with an aseptic non-touch technique (ANTT) prevents wound contamination and reduces healthcare-associated infection risk.

Which of the following best reflects a formative use of the OSCE?

Answer: Providing mid-year feedback to residents on their clinical skills gaps

Formative OSCEs are used for learning and development feedback rather than high-stakes pass/fail decisions.

During abdominal examination, in which quadrant would you expect to find Murphy's sign positive?

Answer: Right upper quadrant

Murphy's sign (inspiratory arrest on deep palpation) is elicited in the right upper quadrant over the gallbladder.

Which of the following actions best demonstrates respect for cultural competence in clinical practice?

Answer: Asking open-ended questions about cultural or religious factors that may influence care preferences

Cultural competence requires individualized inquiry rather than stereotyping, enabling care that aligns with each patient's values.

When designing an OSCE blueprint, which psychometric principle guides the selection of how many stations to include?

Answer: More stations increase content validity and improve reliability by sampling broadly

Reliability improves with more stations because broader sampling reduces the influence of any single station's variability on the overall score.

Which type of wound healing is characterized by surgical closure with sutures or staples?

Answer: Primary intention (first intention)

Primary intention healing involves wound closure by direct apposition of wound edges (sutures, staples, steri-strips), resulting in minimal scarring and rapid healing.

During cardiovascular examination you note Kussmaul's sign — the JVP rises paradoxically on inspiration. This is most pathognomonic of which condition?

Answer: Constrictive pericarditis

Kussmaul's sign is pathognomonic for constrictive pericarditis, where a rigid, fibrotic pericardium prevents right heart expansion on inspiration, causing JVP to rise rather than fall.

What is the most important factor in effective communication with patients regarding clinical reasoning?

Answer: Using clear, understandable language and confirming understanding

Clear communication in understandable language, with confirmation of understanding, improves patient compliance and outcomes.

Which preparation strategy best helps students manage the transition bell between OSCE stations?

Answer: Practicing a brief reset ritual such as deep breathing to clear cognitive load

A consistent reset ritual prevents rumination on past stations and re-centers attention on the upcoming station's demands.

How does the OSCE address the limitation of assessing clinical competence through written multiple-choice questions alone?

Answer: By directly observing performance of clinical tasks in simulated encounters

OSCEs evaluate actual performance of clinical skills in real-time simulations, which written exams cannot capture.

A student receives written OSCE feedback stating: 'Your examination technique was adequate.' Why is this feedback considered poor quality?

Answer: It lacks specificity, making it impossible to identify what to maintain or improve

Feedback must be specific enough for the learner to identify which behaviors to replicate or change; 'adequate' provides no actionable detail.

The patient who had purple lesions on their palate claimed to have other lesions throughout their body. What is the most likely reason?

Answer: HIV

Purple lesions on the palate, especially when accompanied by other body lesions, are highly suggestive of Kaposi's Sarcoma. This is an opportunistic infection strongly associated with advanced HIV infection, making HIV the most likely underlying cause. These characteristic lesions are typically reddish-purple to brown and can appear on the skin, mucous membranes, and internal organs.

Which statement BEST explains why peer feedback in OSCE practice sessions can be valuable?

Answer: Giving and receiving peer feedback develops self-assessment skills and deepens understanding of performance criteria

The process of evaluating peers requires learners to internalize assessment criteria, which simultaneously improves their self-assessment capacity.

The Romberg test assesses:

Answer: Proprioception and posterior column function of the spinal cord

The Romberg test distinguishes between proprioceptive (posterior column) ataxia and cerebellar ataxia — a positive result occurs only when eyes are closed, indicating proprioceptive deficit.

A drug has a volume of distribution of 500 L in a 70 kg patient. What does this suggest?

Answer: Extensive tissue distribution with low plasma concentration

A large volume of distribution (>42 L) indicates the drug distributes extensively into tissues rather than remaining in plasma.

What is the significance of the 'Battle's sign' in head injury assessment?

Answer: Bruising over the mastoid process (behind the ear), suggesting a base of skull fracture

Battle's sign (mastoid bruising) indicates blood has tracked from a base of skull fracture to the mastoid region — it typically appears 24–72 hours after injury.

What is clonus and what does it indicate neurologically?

Answer: Rhythmic involuntary oscillations of a joint when a muscle is rapidly stretched, indicating an UMN lesion

Clonus is rhythmic, repetitive reflex muscle contraction in response to sudden sustained stretching, indicating upper motor neuron lesion with hyperreflexia.

In OSCE practice, reliability in assessment refers to:

Answer: The consistency and reproducibility of results

Reliability refers to the consistency and reproducibility of assessment results when the test is repeated under similar conditions.

What is the correct order for donning personal protective equipment (PPE)?

Answer: Gown, mask, goggles, gloves

The correct donning sequence (gown, mask, goggles, gloves) ensures proper coverage and minimizes contamination risk.

What causes acute pancreatitis most frequently?

Answer: Gallstones

Gallstones are the leading cause of acute pancreatitis, responsible for approximately 35-40% of all cases. They can obstruct the common bile duct or the pancreatic duct, leading to bile reflux into the pancreas and premature activation of digestive enzymes within the gland, which triggers inflammation and autodigestion.
