OSCE MCQ 5

Question 1

In an OSCE station on blood pressure measurement, which technique error most commonly leads to a falsely elevated reading?

Accepted Answer

Using a cuff that is too small

Answer

An undersized blood pressure cuff compresses tissue unevenly and requires excess pressure, leading to falsely elevated readings.

Question 2

During a surgical OSCE station on wound assessment, which feature of an ulcer suggests a venous rather than arterial etiology?

Accepted Answer

Shallow ulcer with sloping edges around the gaiter area

Answer

Venous ulcers are typically shallow with sloping edges located in the gaiter area (medial lower leg) and are often associated with varicosities and hemosiderin deposition.

Question 3

An OSCE candidate is asked to perform a Rinne test. A negative Rinne test (bone conduction > air conduction) indicates:

Accepted Answer

Conductive hearing loss

Answer

A negative Rinne test (BC > AC) indicates conductive hearing loss, as the normal air-conduction advantage is lost due to a middle ear or external ear problem.

Question 4

In an OSCE station on nasogastric tube insertion, how is correct gastric placement most reliably confirmed?

Accepted Answer

Chest X-ray confirming position below the diaphragm

Answer

Chest X-ray is the gold-standard method to confirm NG tube placement, as auscultation and pH testing alone are insufficient per national safety guidelines.

Question 5

During an OSCE paediatric station, which developmental milestone should a typically developing 18-month-old child have achieved?

Accepted Answer

Walking independently

Answer

Independent walking is expected by 12–15 months; at 18 months, walking independently is a firm milestone that should be present.
