20 QUESTIONS · 5 TOPICS · DOSING SIMULATOR · ABOUT 15 MINUTES

The first pacemaker was the size of a TV. Now one fits inside the heart.

In 1958 Earl Bakken's external pacemaker ran off a car battery. Today's leadless models are smaller than a AAA battery and last over a decade. Bioengineering applies engineering to living systems. Twenty questions, each explained, then plan a drug dose. No sign-up, nothing saved.

DOSING SIMULATOR · PHARMACOKINETICS

Keep a drug in the therapeutic window

Too little drug in the blood does nothing; too much is toxic. Each dose adds a spike that the body then clears at a rate set by the drug's half-life. Repeated doses stack up until they level off at a steady state.

In the window at steady state.The level swings between 5.0 and 10.0 mg/L. Steady state takes about 36 h (4–5 half-lives), so doctors sometimes give a bigger 'loading dose' first.
A one-compartment model with instant absorption and a 50 L volume of distribution. The window (4–12 mg/L) is illustrative, not medical advice; real dosing depends on the drug and the patient.

What this bioengineering test covers, in short

Twenty multiple-choice questions at first-year university level, four on each of five topics: biomechanics, biomaterials, medical devices and imaging, tissue engineering, and drug delivery. It sits where engineering, biology and medicine meet.

Related tests: biotechnology, classical mechanics and the human body. This test is our own and not normed.
