Question 1

According to INS standards, how frequently should administration sets used for continuous non-lipid infusions be routinely changed?

Accepted Answer

Every 96 hours or longer unless clinically indicated

Answer

INS and CDC guidelines recommend changing continuous non-lipid, non-blood administration sets no more frequently than every 96 hours (and up to 7 days) to reduce infection risk and cost.

Question 2

A vascular access nurse is reviewing a patient's central line for daily necessity. Which of the following is the PRIMARY criterion for determining if the line should be removed?

Accepted Answer

The patient no longer has a clinical indication for central venous access

Answer

Daily line necessity review is a core CLABSI bundle element; a line with no current clinical indication should be removed promptly to eliminate infection risk.

Question 3

Which of the following correctly describes catheter pinch-off syndrome?

Accepted Answer

Compression of the catheter between the clavicle and first rib causing intermittent occlusion

Answer

Pinch-off syndrome occurs when a subclavian catheter is compressed between the clavicle and first rib, causing intermittent or positional occlusion and risk of catheter fracture.

Question 4

A patient with a tunneled hemodialysis catheter is found to have CRBSI caused by S. aureus. After catheter removal, what is the MINIMUM recommended duration of systemic antibiotic therapy?

Accepted Answer

4–6 weeks

Answer

S. aureus CRBSIs carry a high risk of endovascular complications (endocarditis, septic emboli) requiring 4–6 weeks of systemic antibiotics after catheter removal per IDSA guidelines.

Question 5

Which of the following is the MOST appropriate action when a needleless connector has visible blood residue or debris?

Accepted Answer

Change the connector immediately before accessing the line

Answer

Visible contamination of a needleless connector warrants immediate replacement; scrubbing alone is insufficient to eliminate debris or blood that harbors microorganisms.
