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 C
Explanation
Choice A rationale
Washing hands after glove removal is not directly related to preventing latex allergy, which is better managed by avoiding latex products and using alternative materials.
Choice B rationale
Washing hands does not enhance the ease of donning a fresh pair of gloves but is critical for removing any contaminants that may have come in contact with the hands during glove removal.
Choice C rationale
The primary reason for washing hands after removing gloves is to avoid the transfer of organisms. Hands can become contaminated during glove removal, and washing them ensures that any potential pathogens are removed.
Choice D rationale
While washing hands can help keep the skin from cracking and drying, this is not the main reason for handwashing after glove removal. The main goal is to maintain proper hygiene and prevent the spread of infection. .
Correct Answer is B
Explanation
Choice A rationale
Interferons are proteins produced by cells in response to viral infections and are part of the body's immune response, but they are not directly involved in the engulfing of pathogens.
Choice B rationale
Phagocytosis is the process by which certain cells, such as macrophages and neutrophils, engulf and destroy pathogens. This is a crucial mechanism of the innate immune system.
Choice C rationale
Creating antibodies is the function of B cells in the adaptive immune system, which works alongside phagocytosis but is not the same process.
Choice D rationale
Phagocytosis itself does not stimulate the body to make more white blood cells, but it is a function performed by existing white blood cells to eliminate pathogens.
