Appeared in: Combined AIIMS - 2020 (Jodhpur, Bhopal, Patna, Raipur)

Explanation

  • The image shows a dark-colored, single-strand (monofilament) suture.
  • Nylon is a synthetic, non-absorbable, monofilament suture, which perfectly matches the visual evidence.
  • It is commonly dyed black for better visibility during surgical procedures, especially for skin closure.
  • Brand names for Nylon sutures include Ethilon and Monosof.

Why Other Options Were Wrong

  • Option B: Plain catgut is a natural, absorbable suture that is typically yellowish-tan in color and has a twisted, not monofilament, structure.
  • Option C: Prolene is a synthetic monofilament like nylon, but it is characteristically dyed blue. While it appears dark in a black-and-white image, nylon is the more common suture that is dyed black.
  • Option D: Cotton is a natural, braided (multifilament) suture. The image clearly shows a smooth, single strand (monofilament), which rules out cotton.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of surgical suture materials based on visual characteristics as background academic context rather than a clinical decision trigger.
  • Choosing the correct suture is critical for proper wound healing. A nurse must be able to identify suture types to monitor the wound correctly and provide appropriate patient education.
  • Using a non-absorbable suture like nylon on the skin requires the patient to return for suture removal, a key point for patient discharge teaching.
  • What if the wound was internal, such as on the small bowel? An absorbable suture like Vicryl or PDS would be used, as a non-absorbable suture like nylon could become a nidus for infection or obstruction.
How to Approach the Question
  • First, carefully analyze the image provided. Identify the key physical characteristics of the suture: Is it a single strand (monofilament) or braided (multifilament)? Note its color and texture if discernible.
  • The image shows a smooth, single strand, indicating it is a monofilament suture. This immediately helps eliminate options that are multifilament (e.g., Cotton, Silk).
  • Next, consider the properties of the remaining options. The suture is dark.
  • Evaluate the monofilament options: Nylon is commonly black, Prolene is blue, and Catgut is yellowish-tan.
  • Based on the dark color and monofilament structure, Nylon is the most plausible identification among the choices.
  • Confirm your choice by recalling the common uses. Nylon is very frequently used for skin closure, which is a common procedure depicted in general questions.
Concept Tested & Keywords
  • Concept Tested: Identification of surgical suture materials based on visual characteristics.
  • Stem keywords: suture, image
  • Lead-in keywords: is
  • Clinical cues: The image shows a dark, monofilament suture attached to a curved needle, which is a key visual cue for identification.
