✍️ Sample CABT Questions & Answers

1. What is the anatomical term for the anterior surface of the hand?
✓ Palmar

The palmar surface refers to the front (anterior) surface of the hand, also called the palm.

2. A capacitor is connected in series with a resistor to an AC source. As frequency increases, what happens to the capacitive reactance (Xc)?
✓ Xc decreases

Capacitive reactance Xc = 1/(2πfC), so as frequency increases, Xc decreases.

3. What is the recommended action when an automated analyzer's QC result exceeds the 3-SD (3 standard deviation) Westgard rule?
✓ Reject the run, investigate the cause, and do not report patient results until resolved

A 3-SD violation (1₃s rule) indicates random error and requires run rejection, root cause investigation, and re-running QC before releasing patient results.

4. In a physiologic monitoring system, what is a 'zeroing' procedure used for?
✓ Establishing the atmospheric pressure as the baseline reference for invasive pressure measurements

Zeroing an invasive pressure transducer exposes it to atmospheric pressure and sets that as the zero reference point, ensuring all subsequent pressure measurements are accurate relative to atmosphere.

5. Which error in a clinical laboratory water purification system would most directly affect enzyme assays performed that day?
✓ Elevated conductivity indicating ion contamination

Elevated conductivity signals the presence of ionic contaminants that can inhibit enzyme activity and alter assay results significantly.

6. When calibrating a pressure transducer to atmospheric pressure, the biomedical technician should confirm the displayed pressure reads:
✓ 0 mmHg

After zeroing to atmospheric pressure, the monitor should display 0 mmHg, as gauge pressure is measured relative to ambient atmospheric pressure.

What Practice Test Geeks adds beyond an AI chat for CABT

An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:

  • A timed, full-length CABT mock exam — 120 questions in 120 minutes with a 70% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
  • A fixed CABT question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
  • Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
  • A printable CABT cheat sheet you can print or save as a PDF.
  • CABT flashcards built from the same question bank.
  • Free CABT practice tests with the correct answer shown after each question.
