What is the first thing a phlebotomist should do in the event of an accidental needle stick?

The color coding of evacuated tubes provides information about all of the following except the: Question options:

Which method remains the "gold standard" for ANA detection?

Which of the following organizations has developed standards to maintain the performance of the clinical laboratory at the highest standards for quality care?

Platelet neutralization tests are one of the confirmatory tests that can be used to determine if a patient has a circulating lupus antibody, or lupus anticoagulant. The principle in this test involved the use of a freeze-thawed platelet suspension that, when mixed with the patient plasma, will neutralize the anti-phospholipid antibodies (lupus anticoagulant) present and allow for a corrected aPTT result upon re-testing.
A patient has a history of repeated spontaneous abortion. Coagulation studies reveal an elevated APTT, normal PT, normal platelet function, and normal clotting time. Schistocytes were seen on the peripheral blood smear.
Which test should be performed to determine if the patient has lupus anticoagulant?

Any oxidase-positive organism can be excluded from the Enterobacteriaceae. The other characteristics are as a rule present in these organisms.
Which of the following is not true about members of the Enterobacteriaceae:

In healthy individuals, procalcitonin is only synthesized by the thyroid C cells. In bacterial infections, PCT is synthesized in various extrathyroidal neuroendocrine tissues.
In healthy individuals, procalcitonin is synthesized by which cells in the body?

The microscopic features shown here represent Scopulariopsis species. In most instances, particularly if a patient does not have underlying immunologic or hematologic disease, Scopulariopsis species should be considered a contaminant when recovered from a sputum specimen. However, if there is clinical or X-ray evidence of mycotic pulmonary infection, additional daily induced sputum specimens should be obtained.
If Scopulariopsis species or any other hyaline mold is recovered from two or more successive specimens, its potential as a pathogenic agent should be considered. Scopulariopsis species have been reported as the agents of pulmonary fungus ball infections in patients with preexistent cavities and as a cause of pneumonia in patients with leukemia.
Invasive pulmonary disease by this agent has not been reported.
The fungus illustrated in this photomicrograph was recovered from an induced sputum specimen from a 74 year old man with chronic obstructive pulmonary disease. This isolate is most likely:

Hb S migrates with D in alkaline and alone in acid electrophoresis.
The gel electrophoresis pattern for hemoglobin S shows which of the following migration patterns?

n reporting out Gram stains, one should not go beyond what objective observation will allow. In this case, bacterial cells are observed, which are spherical and gram-positive. Their arrangement in tetrads and clusters might be helpful to the physician, suggesting staphylococci. However, one should stop short of naming staphylococci in an official report, as the large gram-positive cocci in tetrads is also suggestive of Micrococcus species, for which human infections have not been reported.
A Gram stain of the serous exudate is shown in the image. The appropriate report would read:
