Answer to Question 1
Correct Answer: 4
Rationale 1: Changing the dressing will not decrease the bacterial content of the TPN solution.
Rationale 2: Redness at the IV site can indicate a local site infection.
Rationale 3: Assessing for a change in temperature can indicate infection, but it will not reduce the risk of infection.
Rationale 4: A 0.22-micron inline filter is used to reduce introduction of bacteria from the TPN solution.
Global Rationale: A 0.22-micron inline filter is used to reduce introduction of bacteria from the TPN solution. The other interventions are standard, but do not prevent introduction of bacteria from the fluid. They are site related or are useful for early identification of infection.
