Free Certified Medical Assistant Medical Procedures and Techniques Questions and Answers

Question 1

Which of the following methods is used to sterilize instruments and equipment by subjecting them to steam under pressure?

Accepted Answer

Autoclaving

Answer

Autoclaving is the most effective method for sterilizing heat-stable instruments and equipment. It uses high-pressure saturated steam to kill all microorganisms, including bacterial spores, ensuring a completely sterile environment. Disinfection reduces microorganisms, sanitization cleans, and fumigation uses gas for pest control, not medical sterilization.

Question 2

What is the purpose of the Allen test before drawing blood from the radial artery?

Accepted Answer

To ensure collateral circulation to the hand

Answer

The Allen test is performed before drawing blood from the radial artery to assess the patency of the ulnar artery. This ensures that if the radial artery is compromised during the procedure, the hand will still receive adequate blood supply through collateral circulation, preventing ischemia. It is a crucial safety measure.

Question 3

Which of the following instruments is used to examine the interior of the eye, including the retina and optic nerve?

Accepted Answer

Ophthalmoscope

Answer

An ophthalmoscope is a specialized instrument used to examine the interior structures of the eye, including the retina, optic nerve, and blood vessels. This allows healthcare providers to detect various eye conditions and systemic diseases. A stethoscope is for listening, an otoscope for the ear, and a laryngoscope for the larynx.

Question 4

What is the correct sequence of steps for performing hand hygiene using an alcohol-based hand sanitizer?

Accepted Answer

Apply sanitizer, rub hands, allow to air dry

Answer

The correct sequence for using an alcohol-based hand sanitizer involves applying the product to the palm, rubbing hands together thoroughly to cover all surfaces, and allowing them to air dry completely. There is no rinsing with water involved, as this would dilute the sanitizer's effectiveness. This method ensures proper hand hygiene.

Question 5

Which technique is used to assess the size, shape, and consistency of internal organs by tapping the body's surface?

Accepted Answer

Percussion

Answer

Percussion is the technique of tapping on the body's surface to produce sounds that help assess the size, shape, and consistency of underlying organs. The sounds elicited provide clues about the presence of air, fluid, or solid masses. Auscultation involves listening, palpation involves feeling, and inspection involves visual examination.
