An adult client in the intensive care unit (ICU) with a central venous catheter has developed signs and symptoms that are suggestive of a central line-associated bloodstream infection (CLABSI). What is most likely the cause of the infection?
The client was treated for vancomycin-resistant enterococcus (VRE) during a previous admission.
The client had blood cultures drawn from the central line.
The client's central line dressing was changed using clean technique.
The client has received antibiotics and intravenous fluids through the same line.
The Correct Answer is C
A. The treatment for vancomycin-resistant enterococcus (VRE) in a previous admission is not directly related to the development of CLABSI in the current situation. The infection is more likely caused by improper handling or maintenance of the central line.
B. Drawing blood cultures from the central line, while not ideal, is not the most likely cause of CLABSI. Proper technique can mitigate the risk of introducing infection during this procedure.
C. Changing the central line dressing using clean technique instead of sterile technique increases the risk of introducing pathogens to the central line site, leading to a central line-associated bloodstream infection (CLABSI).
D. Receiving antibiotics and intravenous fluids through the same line does not typically cause CLABSI if the line is properly maintained and sterile techniques are observed during administration.

D. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that has been associated with an increased risk of hearing loss, particularly when taken regularly or in high doses.
E. Bumetanide is a loop diuretic that can also have ototoxic effects, especially when used in conjunction with aminoglycoside antibiotics like gentamycin.
F. Heart failure is not associated with hearing loss
Correct Answer is ["33"]
Explanation
To calculate the infusion rate, we'll use the following formula:
Infusion rate (gtt/min) = (Volume to be infused (mL) / Time (min)) ) x Drop factor (gtt/mL)
First, calculate the total volume to be infused:
- 100 mL / 30 min = 3.33 mL/min
Then, multiply the volume per minute by the drop factor:
- 3.33 mL/min x 10 gtt/mL = 33.3 gtt/min
Therefore, the nurse should set the manual IV infusion to deliver 33 gtt/min.
