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.

Answer and Explanation

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

A 45-year-old in traction for a fractured femur is at risk for infection due to immobility and potential surgical wounds, but not as high as someone with a Foley catheter.

Choice B rationale

A 56-year-old with pneumonia receiving oxygen is at risk for respiratory infections, but the presence of a Foley catheter significantly increases the risk of healthcare-associated infections.

Choice C rationale

A 70-year-old with congestive heart failure attached to a monitor has a risk of infection due to potential breaks in skin integrity, but not as high as someone with a Foley catheter.

Choice D rationale

A 65-year-old with a Foley catheter is at the highest risk for health care-associated infections because the catheter provides a direct pathway for pathogens into the urinary tract, increasing infection risk.

A. Gown, gloves, and mask. B. Reusable gown and mask. C. Gown, gloves, and goggles (or glasses). D. Shoe covers, gown, and gloves.

Correct Answer is C

Explanation

Choice A rationale

Gown, gloves, and a mask are important, but goggles or glasses provide additional protection against splashes, which are common in patients with diarrhea and vomiting.

Choice B rationale

Reusable gowns are generally not recommended in situations where contamination is likely, as they can harbor pathogens even after laundering. Disposable PPE is preferable.

Choice C rationale

Gown, gloves, and goggles (or glasses) offer comprehensive protection. Goggles or glasses shield the eyes from potential splashes, reducing the risk of transmission of infectious agents.

Choice D rationale

Shoe covers are not typically necessary unless there is a risk of floor contamination. The primary focus should be on protecting the areas most likely to be exposed to body fluids, such as the hands, body, and face.
