A group of nurses are discussing risk factors for transmission of human immunodeficiency virus (HIV) from clients. Which of the following individuals should the nurse identify as being at the greatest risk for contracting HIV?
A phlebotomist who collects blood from clients who have HIV.
A nurse who works for an insurance company and collects urine samples from clients who have HIV.
An occupational therapist who works with a client who has HIV.
A personal trainer who works with a client who has HIV.
The Correct Answer is A
Choice A rationale
A phlebotomist who collects blood from clients who have HIV is at the greatest risk for contracting HIV. This is because they are frequently exposed to blood, which is a bodily fluid that can transmit HIV if proper precautions are not taken.
Choice B rationale
A nurse who works for an insurance company and collects urine samples from clients who have HIV is at a lower risk compared to a phlebotomist. Urine is not a common transmission route for HIV.
Choice C rationale
An occupational therapist who works with a client who has HIV is at a lower risk compared to a phlebotomist. Occupational therapists are not typically exposed to blood or other high-risk bodily fluids.
Choice D rationale
A personal trainer who works with a client who has HIV is at a lower risk compared to a phlebotomist. Personal trainers are not typically exposed to blood or other high-risk bodily fluids.

Correct Answer is C
Explanation
Choice A rationale
Headaches and blurred vision are not specific to stage I Lyme disease. These symptoms can occur in many other conditions and are not the primary indicators of early Lyme disease.
Choice B rationale
Tremors and weakness are not typical early signs of Lyme disease. These symptoms are more associated with neurological involvement, which occurs in later stages of the disease.
Choice C rationale
Rash symptoms, specifically erythema migrans (a bull’s-eye rash), are the hallmark of stage I Lyme disease. This rash appears at the site of the tick bite and is a key diagnostic feature.
Choice D rationale
Painful joints are more commonly seen in later stages of Lyme disease when the infection has spread and caused more systemic involvement.
Correct Answer is D
Explanation
Choice A rationale
Sound lateralizing to the right ear during the Rinne test does not indicate conductive hearing loss in the left ear. This result suggests that the right ear may have better hearing or that there is an issue with the left ear, but it does not specifically diagnose conductive hearing loss.
Choice B rationale
Sound lateralizing to the left ear during the Rinne test indicates that the left ear is perceiving the sound better, which could be due to conductive hearing loss in the left ear. However, this option does not provide a definitive result for conductive hearing loss.
Choice C rationale
Air conduction being greater than bone conduction in the left ear is a normal finding and does not indicate conductive hearing loss. In conductive hearing loss, bone conduction is typically better than air conduction.
Choice D rationale
Air conduction being less than bone conduction in the left ear is indicative of conductive hearing loss. This result means that the sound is being conducted through the bones of the skull more effectively than through the air, which is a hallmark of conductive hearing loss.
