A nurse is conducting a community assessment. Which of the following observations indicate individual lifestyle choices in the community?

A. Refer coworkers who might have been exposed to a provider for prophylactic antibiotics: Anthrax exposure can be fatal if not treated early. Public health protocols recommend prophylactic antibiotics such as ciprofloxacin or doxycycline for those potentially exposed. Timely referral helps prevent the onset of disease.

B. Place the employee under quarantine for 14 days: Quarantine is typically used for contagious diseases that spread person to person, such as COVID-19 or influenza. Anthrax is not spread between individuals, so quarantining an exposed person is unnecessary and not a standard public health measure for this pathogen.

C. Alert the family members of coworkers about their possible exposure to anthrax: Because anthrax does not spread from person to person, there is no need to notify family members of potential exposure. Such an action could cause unnecessary alarm and would not contribute to effective disease control or prevention.

D. Instruct the client to wear a mask at work: Wearing a mask does not prevent the progression of anthrax in an exposed individual nor does it protect others, as anthrax is not contagious between humans. This measure would not address the exposure risk or help in disease managemet.

A. Use a dandruff shampoo followed by drying the child's hair on high heat: Dandruff shampoos are not formulated to kill lice or nits, and while high heat may kill some lice, it is not a reliable or complete treatment. This approach may not effectively eliminate an active infestation.

B. Manually remove the lice eggs with a special comb: Manual removal using a fine-toothed nit comb is a safe and effective non-chemical method, especially suitable when natural remedies are preferred. This method ensures physical removal of lice and nits and is often recommended in combination with other treatments for full eradication.

C. Boil the child's combs, brushes, and hair accessories in water for 10 min: While this action is effective for preventing re-infestation by sanitizing personal items, it does not treat the lice on the child. It is an important environmental control measure but not a primary treatment strategy.

D. Apply mayonnaise to the child's head: Mayonnaise is sometimes cited as a natural remedy because it may smother lice, but there is limited evidence supporting its effectiveness. Additionally, it does not reliably kill nits and may not fully resolve the infestation without combing.
