100

This instrument is used to grasp and drive the needle

a needle holder

100

This is the simplest and most common type of suture

simple interrupted suture

100

The standard, secure knot taught to beginners

a square knot

100

The primary goal of suturing is to achieve this between wound edges

tissue approximation

100

This is the most common complication of improper suturing

wound dehiscence

200

These are toothed or smooth and help in tissue handling

forceps

200

A suture technique known for faster closure but at risk if one knot fails

continuous (running) suture

200

This knotting technique is useful in confined spaces, often requiring only one hand

a one-handed square knot

200

Sutures should be placed at this approximate distance from the wound edge

3–5 mm

200

The type of suture material that loses strength in the presence of infection

catgut

300

This instrument is used specifically for cutting sutures

suture scissors

300

This mattress suture provides strong wound edge eversion by a far–far, near–near technique

vertical mattress suture

300

Alternating throws are essential in knot tying to prevent this

a slip knot or knot unravelling

300

Wound edges should be slightly _______ to prevent depressed scars

everted

300

The “rule of halves” refers to this technique in wound closure

bisecting the wound and suturing at the halfway point each time

400

The difference between absorbable and non-absorbable sutures lies in this property

the ability to be broken down by the body

400

This suture spreads tension across fragile skin but may compromise blood supply if too tight

a horizontal mattress suture

400

At least this many throws are recommended for a secure knot

3–4 throws

400

The type of wound closure used for contaminated wounds

delayed primary closure

400

The mattress suture is especially useful over this anatomical area with high tension

over joints

500

The standard curve of a surgical needle used in skin suturing

a 3/8 circle needle

500

The “subcuticular” technique is especially used for this cosmetic reason

minimizing scarring

500

This alternative knot may be used when tying under tension or in deep spaces

a surgeon’s knot 

500

The suture-to-wound length ratio recommended for strength in closure

4:1

500

What is Halsted's suture

approximate, don’t strangulate
