Which of the following is a sign that a patient may be at higher risk for infection?

Having an invasive device in place is a significant indicator that a patient may be at a higher risk for infection. Invasive devices, such as catheters, intravenous lines, or surgical implants, create pathways for pathogens to enter the body, compromising the integrity of the skin and other natural barriers. These devices can become contaminated and serve as reservoirs for bacteria or other microorganisms, increasing the likelihood of infection.

In contrast, receiving routine preventive care, being in good health overall, and being a frequent visitor to the clinic do not inherently increase infection risk. Preventive care is aimed at reducing the likelihood of health complications, and good overall health generally correlates with a stronger immune system that can fend off infections. Frequent clinic visits may indicate ongoing health management but do not automatically imply increased risk without the presence of other risk factors.
