Free Patient Care Technician Certification Questions and Answers

Question 1

Typically, a tube with a green stopper contains

Accepted Answer

Thrombin

Answer

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?

Accepted Answer

Nucleus

Answer

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:

Accepted Answer

Left anterior hemiblock

Answer

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?

Accepted Answer

Arteriospasm

Answer

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."

Accepted Answer

Overseen by the hospital administrator through periodic reports

Answer

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.
