Mr. J, aged 38 years, presents to the clinic today for his routine physical. During the review of systems, he offhandedly mentions that he has a "knot" in his neck, but he figures it is no big deal since it does not hurt. He also reports occasional fever and chills, and the last several weeks, he has awakened drenched in sweat. He attributes this to the fact that he was around his niece and nephew who were both recovering from the flu. 1. What other questions would be helpful to determine the source of these symptoms?

2. The healthcare provider (HCP) has ordered a chest x-ray because he is suspicious of Hodgkin lymphoma. What is the rationale for this order?

Lyme disease is caused by a bacterium transmitted to people by deer ticks. deer ticks are almost never born infected with the bacterium, but they can pick it up from feeding on an infected host in any of the tick's three successive stage of development: larva, nymph, adult. once infected, a tick remains infected through any subsequent developmental stages, but since a tick feeds on only one host in each stage, it follows that . people can be infected only by being bitten by a tick that is either in larval stage or in the nymph stage b. people cannot be infected by a tick that picked up the lyme disease bacterium in the adult stage c. it is not possible for a person to be infected by a tick that is in the nymph stage or by a tick that was infected with the bacterium while in the nymph stage d. people infected with the lyme disease bacterium cannot transmit bacterium to adult deer ticks e. only deer ticks that are adults can transmit the lyme disease bacterium to people
