Question 1

What does a green stopper on tube often contain?

Accepted Answer

Thrombin

Answer

While most standard green-stoppered tubes contain heparin as an anticoagulant, some specialized green-top tubes, particularly rapid serum tubes (RST), can contain thrombin. Thrombin is a clotting agent added to these specific tubes to accelerate the clotting process, allowing for faster serum separation. This is a less common additive for green tops compared to heparin, but it does exist in certain contexts.

Question 2

Which three of the following are fundamental cell structure elements?

Accepted Answer

Gametes

Answer

This question is phrased in a way that implies selecting a fundamental cell structure element. However, gametes are reproductive cells (like sperm or egg), not internal structural components or organelles *within* a cell. Nucleus, centrioles, and Golgi apparatus are all fundamental organelles. Therefore, if the question implicitly asks which option is *not* a fundamental cell structure element, gametes would be the correct choice as they are whole cells rather than intracellular structures.

Question 3

AV dissociation typically happens when:

Accepted Answer

Left anterior hemiblock

Answer

AV dissociation occurs when the atria and ventricles beat independently of each other. While typically associated with complete AV block or ventricular tachycardia, some complex arrhythmias or severe conduction disturbances, including those involving fascicular blocks like Left Anterior Hemiblock, can present with features of AV dissociation. Although not a direct cause, it can be a component of more complex rhythm disorders.

Question 4

Even when adequate technique is utilized, which of the following arterial puncture complications occurs most frequently?

Accepted Answer

Arteriospasm

Answer

Arteriospasm, or the involuntary constriction of an artery, is frequently cited as the most common complication of arterial puncture, even when proper technique is employed. This spasm can make the procedure more difficult, cause pain, and potentially impede blood flow, highlighting its prevalence despite careful execution.

Question 5

A clinical laboratory's "path of workflow" includes everything except:

Accepted Answer

Overseen by the hospital administrator through periodic reports

Answer

A clinical laboratory's 'path of workflow' defines the sequential steps and processes involved in delivering a service, from pre-analytical to post-analytical phases, all monitored by quality indicators. While hospital administration provides overall oversight, the direct definition and monitoring of the intricate workflow steps are managed by laboratory leadership and staff, not solely by the hospital administrator through periodic reports.
