A nurse is preparing to administer cefazolin 1 g by intermittent intravenous (IV) bolus over 30 minutes. Available is cefazolin 1 g in 100 mL dextrose 5% in water (D5W). The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero. Only enter numbers and decimals. Do not enter any letters in your answer.)
Answer and Explanation

The Correct Answer is ["33"]

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.

Correct Answer is C

Explanation

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.

Correct Answer is D

Explanation

A. DKA occurs due to a significant deficiency of insulin rather than issues with cell response to insulin. The condition leads to high blood glucose and ketone production because there is not enough insulin to regulate glucose levels effectively.
B. DKA is primarily associated with diabetes mellitus type 1, not type 2. It can occur due to a lack of insulin and is not solely caused by illness, although illness can exacerbate it.
C. DKA is not limited to clients with diabetes mellitus type 1 who experience septic shock. It can occur in anyone with type 1 diabetes due to severe insulin deficiency, though septic shock can complicate the condition.
D. DKA results from a complete absence of insulin, which is characteristic of poorly controlled or undiagnosed diabetes mellitus type 1. This insulin deficiency leads to elevated blood glucose levels and ketone formation.
