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 for 10 seconds is insufficient for effectively removing germs and contaminants from the skin.
Choice B rationale
Washing hands for 1 minute ensures thorough cleaning but might be longer than necessary for routine hand hygiene in many healthcare settings.
Choice C rationale
Washing hands for 2 minutes is recommended at the beginning of a shift to ensure comprehensive removal of any contaminants present on the hands.
Choice D rationale
Washing hands for 15 seconds is more suitable for routine handwashing but not for the initial handwashing at the beginning of the shift, which requires more thorough cleaning. .
Correct Answer is C
Explanation
Choice A rationale
Requiring the use of a facemask by nursing staff is not sufficient alone as a nursing intervention for a surgical incision and IV line access. Comprehensive infection control measures are needed.
Choice B rationale
Maintaining "clean" technique is important, but "sterile" technique would be more appropriate for wound dressing changes and IV site care to prevent infection.
Choice C rationale
Assessing and documenting skin condition around the incision and IV site at each shift is correct because it helps in early identification of signs of infection, ensuring timely intervention.
Choice D rationale
Limiting visitors to immediate family may help reduce infection exposure, but it does not address the primary nursing intervention for monitoring and caring for the surgical incision and IV site.
