CMT Medical Procedures & Techniques

Question 1

What is the first step in preparing a patient for a blood pressure measurement?

Accepted Answer

Ensure the patient is seated with their arm at heart level.

Answer

Proper patient positioning is vital for obtaining an accurate blood pressure reading. The patient should be comfortably seated with their back supported, feet flat on the floor, and the arm being measured supported at heart level. This ensures that hydrostatic pressure does not artificially inflate or deflate the reading, leading to reliable results.

Question 2

Which of the following is the most common site for drawing blood from an adult patient?

Accepted Answer

The median cubital vein

Answer

The median cubital vein, located in the antecubital fossa (inner elbow), is the most common site for drawing blood due to several factors. It is typically large, superficial, and well-anchored, making it easily accessible and less prone to rolling during venipuncture. This location also generally causes less discomfort for the patient compared to other potential sites.

Question 3

How should a Certified Medical Technician prepare a sterile field for a procedure?

Accepted Answer

Clean the area with alcohol and arrange sterile items.

Answer

Preparing a sterile field is a critical step to prevent contamination and infection during medical procedures. This involves first cleaning the designated area with an antiseptic solution, such as alcohol, to reduce microorganisms on the surface. Once disinfected, sterile items are carefully arranged on this prepared surface, ensuring they remain free from pathogens and ready for use.

Question 4

Which of the following is considered a non-sterile procedure?

Accepted Answer

Blood pressure measurement

Answer

A non-sterile procedure is one that does not require the use of sterile instruments or a sterile field because it does not involve breaking the skin or entering a normally sterile body cavity. Blood pressure measurement is a routine vital sign assessment performed externally on intact skin. In contrast, catheter insertion, wound dressing changes, and IV catheter placement are invasive procedures that require strict sterile technique to prevent infection.

Question 5

What is the correct procedure for administering an intramuscular injection?

Accepted Answer

Administer the injection at a 90-degree angle to the skin.

Answer

Administering an intramuscular injection correctly requires inserting the needle at a 90-degree angle to the skin. This ensures the medication penetrates deep into the muscle tissue, bypassing the subcutaneous fat layer. Injecting at this angle promotes proper absorption and minimizes the risk of the medication being deposited into the wrong tissue, which could lead to pain or ineffective treatment.
