There are fewer tobacco users in this section of town. Immunization has become a community norm.

When providing care on a Native American reservation (First Nations reserve), a nurse has prioritized assessments for type 2 diabetes mellitus and fetal alcohol syndrome. How should the nurse's practice be best understood? The nurse should seek specific permission from each client before proceeding with these assessments. The nurse is performing cultural imposition of the majority of American (Canadian) culture and the accompanying beliefs around diabetes and alcohol use. The nurse is correct in assessing for health problems that have a higher incidence and prevalence among this population. The nurse is stereotyping Native Americans (First Nations people) as leading unhealthy lifestyles and abusing alcohol.

The nurse is correct in assessing for health problems that have a higher incidence and prevalence among this population.

A 16-year-old has come to the clinic and asks to talk to a nurse. The teen states that she has become sexually active and is concerned about getting HIV. The teen asks the nurse what she can do to keep from getting HIV. What would be the nurse's best response? "There's no way to be sure you won't get HIV except to use condoms correctly." "Only the correct use of a female condom protects against the transmission of HIV." "There are new ways of protecting yourself from HIV that are being discovered every day." "Other than abstinence, only the consistent and correct use of condoms is effective in preventing HIV."

"Other than abstinence, only the consistent and correct use of condoms is effective in preventing HIV."

While administering a tuberculin (TB) skin test, a client who is HIV positive asks, "I heard from my friends; this test may not work on me since I have HIV." The health care provider's best response would be: "Sometimes immunocompromised clients will have negative results if you are unable to mount a normal immune reaction." "Most of the time, with HIV-positive clients, we see more false-positive results since you may have a similar infection in your body". "This test is 99.9% specific, so it will give us an accurate result." "If your test comes back positive, we will send a blood test off to a special lab to confirm you really have TB before we start treatment."

"Sometimes immunocompromised clients will have negative results if you are unable to mount a normal immune reaction."

A nurse is caring for a client on a four-medication regimen to treat tuberculosis. The nurse discovers that the client isn't taking all medications. What is appropriate for the nurse to say to the client? "Don't you realize that resistance can develop if you don't take your medications properly?" "You must take your medication as instructed. Do you need supervision?" "Why aren't you taking your medications? Don't you want to get better?" "Taking several medications can be difficult. Tell me about the difficulties you're having."

"Taking several medications can be difficult. Tell me about the difficulties you're having."

"What kinds of routines would work for you to ensure that you don't miss doses of your rifampin?" "What can we do to help you stop smoking?" "Have you given any thought to the choices you made that resulted in your getting tuberculosis?" "What do your friends and family think about the fact that you're getting treated for TB?"

The nurse is providing health education about malaria to a traveler who has been prescribed chloroquine. What statement by the client demonstrates an accurate understanding of the epidemiology of malaria? "A major problem with controlling malaria is the mosquito that is resistant to insecticide." "Any mosquito can carry the plasmodium that transmits malaria." "Malaria can live without a host and be contracted from drinking standing water." "Widespread efforts at mosquito control have never been successful."
