✍️ Sample X-Ray Certification Questions & Answers
1. What is the difference between arteries and veins?
Arteries carry blood away from the heart (usually oxygenated) while veins carry blood toward the heart (usually deoxygenated). Arteries have thicker walls to handle higher pressure.
2. What is the ALARA principle in radiation safety?
ALARA means keeping radiation doses as low as reasonably achievable while still obtaining diagnostic-quality images, balancing benefit against risk.
3. For a geriatric patient who cannot stand for an upright chest, the BEST alternative is:
Seating the patient upright at the table end with an upright grid produces a more diagnostic PA-equivalent chest image than a supine AP projection.
4. Which image quality finding on a chest radiograph confirms adequate inspiration for a PA projection?
Adequate inspiration for a PA chest is confirmed when at least 10 posterior ribs are visible above the right hemidiaphragm.
5. Using a faster (higher speed) image receptor system primarily benefits patient protection by:
Faster receptor systems require less radiation to produce a diagnostic image, directly reducing patient dose.
6. Stochastic radiation effects are characterized by which of the following?
Stochastic effects (e.g., cancer induction) have a probability that increases with dose, but their severity is independent of the dose received.
