Which of the following causes highest risk of nosocomial infection to a patient –
**Core Concept**
Nosocomial infections, also known as hospital-acquired infections, are infections that patients acquire during their stay in a healthcare facility. These infections can be caused by various factors, including medical devices, contaminated equipment, and healthcare worker hygiene.
**Why the Correct Answer is Right**
The correct answer is **C. Central Venous Catheter (CVC)**. CVCs are medical devices used to administer medications, fluids, and nutrients directly into a patient's bloodstream. They are a common cause of nosocomial infections, particularly bloodstream infections, due to the risk of bacterial colonization and subsequent infection. The use of CVCs allows bacteria to enter the bloodstream, leading to sepsis and potentially life-threatening infections.
**Why Each Wrong Option is Incorrect**
* **Option A:** Urinary catheters are another common cause of nosocomial infections, but they are not as high-risk as CVCs. Urinary tract infections (UTIs) are a common complication of urinary catheter use.
* **Option B:** Ventilators are medical devices used to support patients who require mechanical ventilation. While ventilators can contribute to nosocomial infections, such as ventilator-associated pneumonia (VAP), they are not as high-risk as CVCs.
**Clinical Pearl / High-Yield Fact**
It's essential to note that CVCs are a high-risk medical device for nosocomial infections, and healthcare workers must follow strict guidelines for insertion, maintenance, and removal to minimize the risk of infection.
**Correct Answer:** C. Central Venous Catheter
