Sample CCMA practice questions

Try a few representative questions below. Each includes the correct answer and a short explanation — the same style you'll see in the full practice test.

1. Question 1Laboratory Interpretation

   A patient presents with a new diagnosis of type 2 diabetes mellitus. The physician orders a fasting plasma glucose (FPG) test and a hemoglobin A1c (HbA1c). The FPG result is 135 mg/dL. The HbA1c is reported as 7.2%. According to the American Diabetes Association (ADA) guidelines, what is the most appropriate interpretation of these results?

   • A.Both the FPG and HbA1c results indicate uncontrolled diabetes mellitus.(Correct)
   • B.The FPG indicates diabetes, but the HbA1c suggests good control, requiring further investigation into pre-analytical errors.
   • C.The patient has well-controlled diabetes with optimal glycemic management.
   • D.The FPG is within the pre-diabetic range, and the HbA1c is acceptable for a newly diagnosed patient.

   Explanation

   According to ADA guidelines, a fasting plasma glucose (FPG) of 126 mg/dL or higher on two separate occasions is diagnostic of diabetes. An HbA1c of 6.5% or higher is also diagnostic. The FPG of 135 mg/dL and HbA1c of 7.2% both meet the diagnostic criteria for diabetes and indicate that glycemic control is not optimal.

2. Question 2Phlebotomy Techniques

   A medical assistant is preparing a patient for a venipuncture. The patient has a history of difficult veins due to obesity and previous chemotherapy. Which of the following venipuncture techniques is most appropriate to attempt first?

   • A.Tourniquet application for a prolonged duration (over 2 minutes) to engorge the veins.
   • B.Drawing from an antecubital vein using a syringe transfer device to control vacuum.
   • C.Standard straight needle with a larger gauge (e.g., 18-gauge) to ensure rapid blood flow.
   • D.Butterfly (winged infusion) needle set with a smaller gauge needle (e.g., 23-gauge).(Correct)

   Explanation

   For patients with difficult veins, particularly due to obesity or prior treatments like chemotherapy, using a butterfly (winged infusion) needle set is often preferred. These sets allow for greater flexibility and control, and a smaller gauge needle (like 23-gauge) can minimize trauma to fragile veins, reducing the risk of hematoma.

3. Question 3Diagnostic Procedures

   A patient is scheduled for a Holter monitor placement. The medical assistant is reviewing the patient's instructions. Which of the following statements by the patient indicates a need for further education?

   • A."I can shower normally, but I must ensure the electrodes stay dry."(Correct)
   • B."I should avoid using my electric razor while wearing the monitor."
   • C."I will need to return in 24 hours to have the monitor removed."
   • D."I need to keep a diary of my activities and any symptoms I experience."

   Explanation

   Patients wearing a Holter monitor are typically instructed to avoid showering or bathing as the electrodes and monitor are not waterproof. They may be advised to use a sponge bath. The other statements are correct instructions regarding Holter monitoring.
