A patient has been diagnosed with Rocky Mountain spotted fever. The nurse recognizes this disease is caused by a tick bite that infected the patient with:
Coxiella burnetii.
Rickettsia rickettsii.
Aspergillus.
Rickettsia prowazekii.
The Correct Answer is B
Choice A rationale
Coxiella burnetii is the causative agent of Q fever, not Rocky Mountain spotted fever. This bacterium is transmitted through inhalation of contaminated aerosols from infected animals.
Choice B rationale
Rickettsia rickettsii is the causative agent of Rocky Mountain spotted fever. It is transmitted through the bite of infected ticks and causes symptoms like fever, headache, and a characteristic rash.
Choice C rationale
Aspergillus is a genus of fungi that causes aspergillosis, not Rocky Mountain spotted fever. Aspergillosis primarily affects the respiratory system and is not transmitted by tick bites.
Choice D rationale
Rickettsia prowazekii is the causative agent of epidemic typhus, not Rocky Mountain spotted fever. It is transmitted through the bite of infected body lice and causes symptoms like high fever, chills, and rash. .

Correct Answer is D
Explanation
Choice A rationale
Washing hands when visibly soiled removes dirt, debris, and pathogens, effectively reducing the risk of infection.
Choice B rationale
Washing hands after using the restroom is a critical practice to prevent the spread of gastrointestinal pathogens.
Choice C rationale
Washing hands before meal preparation prevents the transmission of pathogens to food, protecting against foodborne illnesses.
Choice D rationale
Hands that appear clean may still harbor pathogens. Effective hand hygiene includes washing hands for at least 20 seconds with soap and water to remove invisible pathogens. .
Correct Answer is C
Explanation
Choice A rationale
Symptoms of an infection may not always appear within 48 hours. The incubation period varies depending on the infectious agent and can range from hours to weeks, during which the person may not show any signs of illness.
Choice B rationale
A person in the incubation period does not exhibit symptoms and, therefore, is unlikely to seek medical attention for symptom relief. Medical attention is usually sought when symptoms manifest and impact the person's well-being.
Choice C rationale
During the incubation period, the person can transmit the disease to others even if they do not feel ill. This period involves the replication of the pathogen within the host, and the person may be contagious without knowing it.
Choice D rationale
Identifiable signs of a specific illness appear during the symptomatic phase, not during the incubation period. The incubation period is the time between exposure to the pathogen and the appearance of initial symptoms.
