In what kind of solution is this cell immersed?

In what kind of solution is this cell immersed: isotonic, hypotonic, or hypertonic? If water is flowing out of the cell then the water outside the cell has more nutrients. Therefore the solution outside the cell is hypertonic to the cell; it is the solution with a higher concentration. The cell would be hypertonic.

What causes a Clabsi?

Key Facts. A central line bloodstream infection (CLABSI) occurs when bacteria or other germs enter the patient’s central line and then enter into their bloodstream. These infections are serious but can often be successfully treated. Health care workers, patients and families can play an active role in CLABSI prevention …

How is Clabsi treated?

Treatment of a CLABSI needs to commence promptly. This can include the use of intravenous antibiotics as well as using supportive measures, such as intravenous fluid administration and oxygen therapy if required, and in conjunction with the ongoing monitoring and assessment of the patient. The CVAD may also be removed.

How long does it take for a Clabsi to develop?

A central line-associated bloodstream infection (CLABSI) is defined as a laboratory-confirmed bloodstream infection not related to an infection at another site that develops within 48 hours of a central line placement. Most cases are preventable with proper aseptic techniques, surveillance, and management strategies.
