Question 1
RIBA stands for which assay?
Correct Answer:
Recombinant immunoblot assay
Explanation:
RIBA stands for Recombinant Immunoblot Assay. The term “immunoblot” refers to a blot-based test that detects antibodies in a person’s serum by measuring binding to specific proteins. The “recombinant” part means the antigens used are recombinant proteins, chosen to target particular HIV components and improve specificity. This naming is the standard way labs describe this confirmatory HIV antibody test, distinct from a general “analysis,” a concept like “randomized,” or a nonstandard phrasing such as “reactive immunoblot approach.”
Question 2
Which professional is listed as the attending on the face sheet?
Correct Answer:
Attending Doctor
Explanation:
The attending on the face sheet is the physician ultimately responsible for the patient’s medical care during the hospitalization. This person oversees the treatment plan, signs orders, and coordinates decisions with the care team and consultants. A nurse wouldn’t be listed as the attending, and while an admitting resident may have evaluated the patient early on, the attending doctor is the supervising physician accountable for ongoing management. Advanced billing isn’t a person, so it wouldn’t appear as the attending.
Question 3
What is disinfection?
Correct Answer:
Use of liquid chemicals to kill many bacteria on inanimate surfaces
Explanation:
Disinfection is the use of chemical agents to destroy or greatly reduce the number of pathogenic microorganisms on inanimate objects to a level considered safe for handling. It does not apply to living tissue (that’s antisepsis) and it does not guarantee complete sterility. The best description here is using liquid chemicals to kill many bacteria on inanimate surfaces, because it targets non-living objects and lowers harmful microbes without achieving total sterilization. The other options describe antisepsis (on living tissue) or sterilization (complete elimination of all organisms, often with heat or autoclave conditions).
Question 4
The cornea is best described as which of the following?
Correct Answer:
The clear connective tissue membrane that helps focus light and provides a smooth anterior surface
Explanation:
The cornea is the eye’s transparent front surface that helps focus light. It’s a clear connective tissue membrane that provides a smooth curved surface, giving much of the eye’s refractive power to bend light as it enters. It’s avascular, which keeps it optically clear, with nutrients supplied from tears and the aqueous humor. This isn’t a muscle that controls pupil size, and it isn’t the inner lining of the eyelid, nor a vascular layer.
Question 5
The eyelashes that grow from the skin side of the lid margin are called:
Correct Answer:
Cilia
Explanation:
Eyelashes are hair that grow from follicles in the skin along the edge of the eyelid. The term for these eyelashes is cilia. The conjunctiva is the mucous membrane that lines the inside of the eyelids and front of the eyeball, not hair. The ciliary body is a structure behind the iris involved in focusing and fluid production, not eyelash growth. Endothelium is the inner cellular lining of vessels or the cornea, also not related to the lashes.
