BMAT Case Studies & Practical Application 5

Question 1

A patient with type 1 diabetes presents with Kussmaul breathing, fruity breath, and blood glucose of 28 mmol/L. What is the most likely diagnosis?

Accepted Answer

Diabetic ketoacidosis (DKA)

Answer

Kussmaul breathing (deep, laboured respirations), fruity-smelling breath from acetone, and markedly elevated glucose are classic features of diabetic ketoacidosis.

Question 2

A BMAT maths question shows two overlapping circles, each of radius 4 cm, where each circle passes through the other's centre. What is the area of overlap (in cm²)?

Accepted Answer

16π/3 − 8√3

Answer

The lens-shaped intersection area of two circles of radius r, each passing through the other's centre, is (2r² / 3)(2π − 3√3) = (2×16/3)(2π−3√3)/2; for r=4 the result is (16π/3 − 8√3) cm².

Question 3

A clinical scenario describes a junior doctor who discovers a senior colleague has made a prescribing error that has not yet harmed the patient. What is the most appropriate first step?

Accepted Answer

Correct the error, inform the senior colleague professionally, and document the incident

Answer

Patient safety comes first; the error should be corrected immediately, then addressed with the colleague through appropriate channels and documented for learning.

Question 4

In a chemistry case study, iron rusts in the presence of water and oxygen. This reaction is best described as which type?

Accepted Answer

Oxidation of iron to iron(III) oxide

Answer

Rusting is the oxidation of iron (Fe → Fe³⁺) in the presence of water and oxygen to form hydrated iron(III) oxide (rust).

Question 5

A research paper uses a case-control study design to investigate a rare disease. Researchers compare 50 patients with the disease to 200 without it. What measure of association is typically reported in case-control studies?

Accepted Answer

Odds ratio (OR)

Answer

Case-control studies calculate the odds ratio because incidence rates cannot be directly determined from a retrospective design that selects on outcome.
