Wash the area thoroughly with soap and water. (Correct answer)

Correct answer: Wash the area thoroughly with soap and water.

The immediate priority after a needlestick or sharps injury is to clean the exposed area. The CDC recommends washing the wound with soap and water. After cleaning the wound, the incident should be reported immediately to a supervisor to ensure proper follow-up and post-exposure prophylaxis can be initiated if necessary.

Question 59: A Certified Medical Technician (CMT) is preparing to assist a resident with a dressing change for a wound with a large amount of drainage. According to Standard Precautions, which combination of Personal Protective Equipment (PPE) is MOST appropriate for the CMT to wear?

Gloves only
Gown and mask only
Gloves and face shield
Gloves and gown (Correct answer)

Correct answer: Gloves and gown

Standard Precautions require wearing gloves when contact with blood, body fluids, or non-intact skin is possible. A gown is necessary to protect skin and clothing from splashes or sprays of body fluids, which is likely with a heavily draining wound. A mask and face shield would be needed if splashes to the face were anticipated, but gloves and a gown are the most essential items in this scenario.

Question 60: Which blood cells are primarily responsible for transporting oxygen?

Platelets
Plasma cells
Red blood cells (Correct answer)
White blood cells

Correct answer: Red blood cells

Red blood cells (erythrocytes) contain hemoglobin, which binds to oxygen for transport throughout the body.

Question 61: A Certified Medical Technician (CMT) is preparing to administer a medication to a resident. The Medication Administration Record (MAR) says to give 'Lisinopril 10 mg by mouth once daily'. The medication package from the pharmacy is labeled 'Lisinopril 20 mg'. What is the MOST appropriate action for the CMT to take?

Withhold the medication and report the discrepancy to the supervising nurse immediately. (Correct answer)
Use a pill-cutter to split the 20 mg tablet in half to provide the correct 10 mg dose.
Administer the 20 mg tablet because it is the same medication.
Ask the resident if they normally take a 10 mg or 20 mg tablet.

Correct answer: Withhold the medication and report the discrepancy to the supervising nurse immediately.

The 'Six Rights of Medication Administration' include the Right Drug, Right Dose, Right Time, Right Route, Right Patient, and Right Documentation. In this scenario, the dose on the pharmacy label (20 mg) does not match the dose on the MAR (10 mg). A CMT's scope of practice does not include altering medication dosages. Therefore, the safest and most appropriate action is to stop the administration process and immediately report the discrepancy to the supervising nurse for clarification and resolution.

Question 62: When a CMT applies a medicated patch, the drug is absorbed through the skin to enter the bloodstream. To do this, the medication must pass through the epidermis and reach which underlying layer that contains blood vessels?

Stratum corneum
Subcutaneous tissue
Hypodermis
Dermis (Correct answer)

Correct answer: Dermis

The dermis is the layer of skin directly beneath the epidermis. It is rich in blood vessels, nerves, and glands. For a medication to have a systemic effect, it must be absorbed into the capillaries located within the dermis.

Question 63: Which site is most commonly used to assess pulse in an unresponsive adult?

The median cubital vein (Correct answer)
The jugular vein
The radial artery
The femoral artery

Correct answer: The median cubital vein

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 66: Which of the following is a critical step in preparing a 24-hour urine specimen container for a patient?

Ensuring the container is filled to the very top.
Instructing the patient to collect the very first morning void.
Adding the required preservative to the container before collection begins. (Correct answer)
Labeling the container with only the patient's name.

Correct answer: Adding the required preservative to the container before collection begins.

For many 24-hour urine tests, a specific preservative is required to maintain the integrity of the analyte being measured. This preservative must be added to the collection container before the patient begins collecting the urine to ensure it mixes with the specimen from the start.

Question 67: What is the meaning of the term 'hematology'?

Study of blood (Correct answer)
Study of the lungs
Study of the skin
Study of the heart

Correct answer: Study of blood

The term 'hematology' is derived from the Greek word 'haima,' meaning blood, and the suffix '-ology,' meaning the study of.
