CNOR Certification MCQ 5

Question 1

Which type of suture material is MOST appropriate for closing a contaminated wound where absorption over several weeks is needed?

Accepted Answer

Polydioxanone (PDS) – synthetic absorbable monofilament

Answer

PDS is a synthetic monofilament absorbable suture that resists infection better than braided materials and maintains tensile strength for 4–6 weeks.

Question 2

A surgeon requests a frozen section during a thyroidectomy. The perioperative nurse's role includes:

Accepted Answer

Properly labeling and transporting the specimen to pathology per institutional protocol

Answer

The perioperative nurse is responsible for correct specimen identification, labeling, and timely transport; frozen sections must NOT be placed in formalin.

Question 3

When sterilizing a complex multi-lumen instrument, the perioperative team must ensure that:

Accepted Answer

All lumens are flushed, the instrument is fully disassembled, and the sterilant contacts all surfaces

Answer

Sterilization efficacy requires direct sterilant contact with every surface; complex instruments must be disassembled and lumens flushed so no bioburden is shielded.

Question 4

The 'clean to dirty' principle in the sterile field means:

Accepted Answer

Procedures always progress from the least contaminated area to the most contaminated area

Answer

Moving from clean to dirty areas prevents cross-contamination — for example, a bowel anastomosis proceeds from mucosa to serosa to avoid spreading luminal contents.

Question 5

A patient receives a peripherally inserted central catheter (PICC) the morning of surgery for IV access. Before induction, the perioperative nurse should verify:

Accepted Answer

Catheter tip position confirmed by chest X-ray and patency of all lumens

Answer

Central line tip position must be radiographically confirmed before use to prevent complications such as cardiac arrhythmia or perforation from malposition.
