A nurse is preparing to administer vancomycin 250 mg PO. The amount available is vancomycin 125 mg/ capsule. How many capsules should the nurse administer to the client with each dose? (Round to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

A. Endogenous Infection: Endogenous infections originate from the client's own microbiota and typically do not involve medical interventions such as urinary catheterization.
B. Systemic Infection: Systemic infections affect the entire body and may not necessarily be related to the urinary tract.
C. Exogenous Infection: Exogenous infections originate from sources outside the client's body.
While the urinary tract infection could be caused by bacteria from the environment, it is more specifically categorized as a healthcare-associated infection (HAI) due to the indwelling urinary catheter being a risk factor.
D. Health Care-Associated Infection: A healthcare-associated infection (HAI) occurs as a result of healthcare interventions and can include infections related to urinary catheterization, surgery, or other medical procedures.

A. A 49-year-old who works in food services: While individuals working in food services may be at risk of exposure to influenza, they are not in the highest priority group. Age and underlying health conditions are typically prioritized over occupational risk factors.

B. An 88-year-old who lives in an apartment for senior citizens: Older adults, especially those living in congregate settings like senior citizen apartments, are at higher risk of complications from influenza. Therefore, the 88-year-old should have the highest priority to receive the vaccine.

C. A 26-year-old with three young children: While having young children may increase the risk of exposure to influenza, younger adults without underlying health conditions are generally at lower risk of severe complications compared to older adults.

D. A 15-year-old who plays ice hockey: While participation in activities like ice hockey may increase the risk of exposure to respiratory infections, age and health status are more significant factors in determining priority for influenza vaccination.
