FFP that has been thawed at 30 - 37oC and maintained at 1 - 6oC must be transfused within 24 hours. In contrast, "Thawed Plasma" can be used for up to 5 days as a replacement therapy for patients requiring stable clotting factors. Keep in mind that these are two different component types and you are asked about FFP.
Blood Bank
FFP that has been thawed at 30 - 37oC and maintained at 1 - 6oC must be transfused within ___________ after it has been thawed.

正確答案: E
Conversion of only the slant to a pink color in a Christensen's urea agar slant is produced by bacterial species that have weak urease activity. The reaction in the slant to the right is often produced by Klebsiella species, as an example. Strong urease activity is indicated by conversion of the slant and the butt of the tube to a pink color, as seen in the tube to the left. The slant only reaction in the right tube may be seen early on if only the slant had been inoculated; however, with a strong urease producer, both the slant and the butt would turn.
Therefore, the reaction is dependent on the strength of urease activity. If the media had outdated for a prolonged period, either there would be no reaction or the appearance of only a faint pink tinge, either in the slant, the butt or both, again depending on the strength of urease production by the unknown organism.

Electrophoresis uses an electric field to separate molecules based on differences in net electrical charge. The rate of electrophoretic migration is also dependent on the ionic radius of the molecule, the viscosity of the solution through which it is migrating, the electrical field strength, temperature, and the type of supporting medium used.
Electrophoretic separation fundamentally relies on:

正確答案: C
The correct answer which best fits the characteristics in this question is Mycobacterium kansasii.
The remaining Mycobacterium strains can be elimated as:
Mycobacterium marinum is considered a fast-grower.
Mycobacterium scrofulaceum produce deep-yellow to orange pigmented colonies when grown in the either the light or dark.
Mycobacterium avium grows colonies which are nonpigmented in the light and dark which do not intensify after light exposure.
What is the MOST likely identification of an acid-fast bacillus that demonstrates the following characteristics?
slow growth
cream to tan colored colonies when grown in the dark
development of yellow pigment upon exposure to light
