Free Patient Care Technician Certification Questions and Answers — Questions and Answers
Question 1: Typically, a tube with a green stopper contains
- Heparin
- Thrombin (Correct answer)
- EDTA
- Sodium citrate
Correct answer: Thrombin
Tubes with a green stopper typically contain heparin (sodium, lithium, or ammonium heparin) as an anticoagulant. Heparin works by inhibiting thrombin, thereby preventing the formation of a fibrin clot. These tubes are commonly used for plasma determinations in chemistry tests, as they yield plasma rather than serum.
Question 2: Which three of the following are fundamental cell structure elements?
- Golgi apparatus
- Gametes
- Nucleus (Correct answer)
- Centrioles
Correct answer: Nucleus
The three fundamental components of a cell are the cell membrane, cytoplasm, and nucleus. The nucleus is particularly crucial as it houses the cell's genetic material (DNA) and controls all cellular activities, making it a core structural and functional element essential for cell life and reproduction. The other options are either organelles or specialized cells.
Question 3: AV dissociation typically happens when:
- Left anterior hemiblock (Correct answer)
- Wenckebach block
- First-degree AV block
- Mobitz type II block
Correct answer: Left anterior hemiblock
AV dissociation, where the atria and ventricles beat independently, can occur in various cardiac conditions. A left anterior hemiblock is a specific conduction disturbance within the heart's electrical system that can contribute to or be associated with AV dissociation, particularly in the context of more advanced heart blocks. It indicates a problem with the electrical pathway in the left ventricle.
Question 4: Even when the good technique is utilized, which of the following arterial puncture complications occurs most frequently?
- Hematoma
- Thrombus formation
- Arteriospasm (Correct answer)
- Infection
Correct answer: Arteriospasm
Arteriospasm, a sudden and involuntary constriction of the artery, is the most common complication encountered during arterial puncture, even when proper technique is utilized. This reaction is often due to irritation of the arterial wall by the needle. While other complications like hematoma or infection can occur, arteriospasm is frequently observed.
Question 5: Everything listed below—except—is a clinical laboratory "path of workflow."
- Made up of preanalytical, analytical, and post-analytical process
- Defined as the steps necessary to deliver a product or service
- Overseen by the hospital administrator through periodic reports (Correct answer)
- Monitored throughout the process by quality indicators
Correct answer: Overseen by the hospital administrator through periodic reports
The clinical laboratory 'path of workflow' encompasses all sequential steps from test ordering to result reporting, typically categorized into pre-analytical, analytical, and post-analytical phases. While hospital administrators have overall oversight, the direct monitoring and management of quality indicators within this workflow are primarily the responsibility of laboratory management and quality assurance teams, not solely the administrator through periodic reports.
Question 6: The waves visible on the EKG reflect, right?
- Both depolarization and repolarization (Correct answer)
- Depolarization
- Neither depolarization and repolarization
- Repolarization
Correct answer: Both depolarization and repolarization
The waves visible on an EKG reflect both depolarization and repolarization of the heart muscle. Depolarization is the electrical activation that precedes muscle contraction, represented by the P wave (atrial) and QRS complex (ventricular). Repolarization is the electrical recovery that allows the muscle to relax, represented by the T wave (ventricular). Both processes are essential for a complete cardiac cycle.
Question 7: A blood bank is also known as a?
- Microbiology
- Immunohematology (Correct answer)
- Serology
- Immunology
Correct answer: Immunohematology
A blood bank is a specialized laboratory section dedicated to blood typing, cross-matching, and the preparation and storage of blood components for transfusion. This field is also known as immunohematology because it involves the study of blood group antigens and antibodies, which are critical for safe blood transfusions.
