TRUE statement about surgical sutures, EXCEPT?

Appeared in: NORCET -4 , 2023

Explanation

The statement about Nylon is false, making it the correct answer to this 'EXCEPT' question.
Nylon is a synthetic, non-absorbable suture, not an absorbable one. It persists in the body and is eventually encapsulated by fibrous tissue.
Nylon is made from polyamide polymers. Polypropylene is a different non-absorbable suture material, known by the brand name Prolene.

Option A: This is a true statement. Vicryl (Polyglactin 910) is a widely used synthetic suture known for being both braided and absorbable.
Option B: This is a true statement. Silk is a classic example of a natural, braided, non-absorbable suture.
Option C: This is a true statement. Monocryl (Poliglecaprone 25) is a common synthetic, absorbable monofilament suture.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification and properties of surgical sutures as background academic context rather than a clinical decision trigger.
Choosing the correct suture is critical for patient outcomes. The choice depends on the tissue type, required wound support duration, and risk of infection.
Using a non-absorbable suture internally where an absorbable one is needed can lead to chronic inflammation, infection, or stone formation (nidus).
Using an absorbable suture for a repair that needs permanent support (like a hernia repair or vessel anastomosis) can lead to premature failure of the repair.

How to Approach the Question

First, identify the keyword 'EXCEPT'. This indicates you must find the statement that is FALSE.
Systematically evaluate each option based on your knowledge of surgical suture classification.
Recall or look up the properties of Vicryl. It is braided and absorbable. So, statement A is true.
Recall or look up the properties of Silk. It is braided and non-absorbable. So, statement B is true.
Recall or look up the properties of Monocryl. It is absorbable. So, statement C is true.
Recall or look up the properties of Nylon. It is non-absorbable and made of polyamide, not polypropylene. Therefore, statement D is false.
