Why surgical assisting is on the CCMA exam

Many CCMA positions involve assisting with minor surgical procedures — biopsies, laceration repairs, I&Ds (incision and drainage), excisions, joint injections, and minor office surgeries. The NHA CCMA exam content outline includes surgical asepsis and assisting as a clinical skill domain. The exam tests the candidate's ability to establish and maintain a sterile field, hand the provider instruments safely, perform surgical skin preparation, and document the procedure.

This post covers the principles of sterile technique, the steps to set up a sterile field, the surgical hand scrub, gloving, surgical site preparation, instrument handling and counting, the most common office-based procedures and the CCMA's role, and post-procedure documentation.

The principles of surgical asepsis

Surgical asepsis (sterile technique) is the practice of eliminating all microorganisms from a field before a procedure that enters sterile tissue. The principles are absolute — once an item becomes unsterile, it cannot be restored.

• A sterile item touches only another sterile item. Unsterile touching sterile contaminates the sterile item.
• A sterile field is established and maintained within a defined boundary. Anything that crosses the boundary unsterile contaminates the field.
• A sterile item held below waist level is considered contaminated (the field is below the level of vision).
• A sterile field is established immediately before use and not left unattended.
• The edges of a sterile package (the 1-inch border) are considered unsterile.
• Sterile items remain sterile only as long as they are protected from contamination.
• If in doubt about sterility, consider the item contaminated and replace it.

The exam tests these principles with scenario questions: "the CCMA dropped a sterile gauze on the floor — what now?" Answer: do not use it. Discard and open a new sterile package.

Surgical hand scrub

The surgical hand scrub prepares the hands and forearms for sterile gloving. The purpose is to remove transient microorganisms and reduce resident microorganisms. The traditional method uses an antimicrobial soap (chlorhexidine or povidone-iodine) and water; the alcohol-based waterless method uses an FDA-approved alcohol-based surgical hand scrub.

The procedure:

1. Remove jewelry, ensure nails are short and clean, and verify that hands and forearms are free of cuts and infections.
2. Wash hands and forearms with antimicrobial soap for 2 to 5 minutes (per manufacturer and facility protocol).
3. Clean nails with a nail cleaner under running water.
4. Scrub each hand and arm systematically — from fingertips to elbow — for the prescribed duration. The hands are scrubbed first, then the forearms.
5. Hold the hands up and away from the body, above waist level, with the elbows flexed.
6. Rinse from the fingertips to the elbows, allowing water to drain away from the clean hands.
7. Dry with a sterile towel, using a separate side of the towel for each hand.

The CCMA enters the procedure room and performs the scrub before donning the sterile gown and gloves.

Donning sterile gloves (open method)

When assisting with minor procedures and not wearing a sterile gown, the CCMA uses the open gloving method:

1. Perform hand hygiene.
2. Open the sterile glove package on a clean, dry surface without contaminating the gloves.
3. Pinch the cuff of the first glove (left glove for the right hand, right glove for the left) and lift it away from the package.
4. Slide the opposite hand into the glove, touching only the inside of the cuff.
5. Slip the gloved fingers under the cuff of the second glove and lift it.
6. Slide the ungloved hand into the second glove, touching only the outside of the second glove (the sterile part).
7. Adjust both gloves without contaminating them.

The closed method (used with a sterile gown) keeps the hands inside the sleeves until the gloves are in place.

Setting up a sterile field

1. Perform hand hygiene.
2. Choose a clean, dry surface at waist level or above. A mayo stand or procedure tray is typical.
3. Open the sterile package by peeling back the outermost layer away from the body. The 1-inch border is considered unsterile.
4. Open additional sterile items (instrument trays, gauze, suture) and drop them onto the field without crossing over the field with the unsterile hand.
5. Pour sterile solutions (sterile saline, sterile water) into a sterile receptacle by holding the bottle so the label faces the palm (prevents the solution from dripping on the label and making it unreadable). Pour from a height of about 6 inches to avoid splashing.

Once the field is established, the CCMA does not turn their back on the field, does not reach over the field, and does not talk directly over the field (respiratory droplets).

Surgical skin preparation

The CCMA performs the surgical prep before the provider begins the procedure. The goal is to remove as many microorganisms as possible from the patient's skin at and around the incision site.

1. Perform hand hygiene and don clean (not sterile) gloves.
2. Position the patient to expose the site.
3. Inspect the site for cuts, abrasions, rash, or signs of infection. If present, notify the provider before proceeding.
4. Clean the site with the antiseptic solution (chlorhexidine, povidone-iodine, or per provider preference).
5. Use a circular motion from the center of the site outward, using a sterile gauze or applicator for each pass. Discard after each pass; do not return to the center.
6. Allow the antiseptic to dry (chlorhexidine dries in about 30 seconds; povidone-iodine in about 60 seconds). The drying time is the contact time for antisepsis.
7. Place sterile drapes to expose only the operative site.

For patients with iodine or shellfish allergy, the provider chooses an alternative antiseptic (chlorhexidine is commonly used; chlorhexidine allergy is rare but exists).

The exam tests the direction of prep (center to periphery, never returning to the center) and the drying time requirement.

Surgical instruments

The CCMA must recognize the common instruments used in minor office procedures and pass them to the provider safely. The passing technique:

1. The CCMA holds the instrument firmly, with the handle toward the provider.
2. The CCMA announces the instrument and any relevant state (e.g., "scalpel with 15 blade" or "curved hemostat, locked").
3. The provider takes the instrument without looking away from the field.
4. The CCMA places the used instrument back on the field or in a designated area, sharp end down and away from other instruments.

Common instruments the CCMA must recognize:

• Scalpel — handle (#3 is standard) and blade (#10, #11, #15 are common). The blade attaches and detaches with a hemostat or blade remover, never by hand.
• Hemostat — clamps blood vessels. Curved (Kelly) or straight. Locking handle.
• Forceps — tissue forceps (toothed, e.g., Adson) and dressing forceps (non-toothed).
• Needle holder — locking, used to hold suture needles.
• Suture scissors — short, sharp, often with one curved blade.
• Retractors — hold tissue away from the operative field (Senn, Army-Navy, Weitlaner).
• Curette — for scraping tissue (skin or uterine biopsies).
• Speculum — for vaginal or ear examination.

Instrument counts

The CCMA performs a count of instruments, sponges, and needles before and after the procedure. The pre-procedure count establishes the baseline; the post-procedure count confirms that no items have been retained in the patient. If the post-procedure count does not match the pre-procedure count, the procedure is not closed until the item is located or imaging confirms it is not in the patient.

Common office procedures the CCMA assists with

Laceration repair

1. The provider assesses the laceration and decides on closure method (sutures, staples, adhesive strips, tissue adhesive).
2. The CCMA sets up the sterile field, performs the surgical prep, and provides local anesthetic at the provider's instruction.
3. The CCMA passes instruments and sutures.
4. After the procedure, the CCMA cleans the area, applies a sterile dressing, and provides patient education (wound care, signs of infection, suture removal date).

Skin biopsy

1. The provider identifies the lesion and marks the biopsy site.
2. The CCMA sets up the sterile field, performs the surgical prep, and provides local anesthetic.
3. The CCMA labels the specimen container with the patient's name, date of birth, the site, and the date and time. The specimen is placed in the appropriate fixative (usually 10% formalin for routine histology; saline or other media for other studies).
4. The biopsy site is closed (sutures or pressure dressing) and dressed.

Incision and drainage (I&D) of an abscess

1. The provider incises the abscess and drains the pus.
2. The CCMA provides culture supplies if a culture is ordered.
3. The wound is packed or dressed.
4. Patient education includes dressing changes, signs of infection, and when to return.

Documentation of surgical procedures

The operative note documents:

• The procedure performed and the indication.
• The patient's tolerance of the procedure.
• Anesthesia used (type, dose, route).
• The site and the prep solution used.
• The instruments and materials used.
• The specimen collected and its disposition.
• The closure method (sutures, staples, adhesive).
• The dressing applied.
• The patient's condition at the end of the procedure.
• The post-procedure instructions and any prescriptions.

The note must be signed by the provider. The CCMA documents their own role (assisted with procedure, performed surgical prep, etc.).

The exam's favorite surgical assisting questions

Question type 1: "The CCMA drops a sterile gauze on the floor. What is the appropriate action?" — Answer: discard the gauze, do not use it, open a new sterile package.

Question type 2: "When pouring a sterile solution into a sterile basin, where should the label face?" — Answer: toward the palm of the pouring hand, so any drips do not obscure the label.

Question type 3: "What is the correct direction for surgical skin prep?" — Answer: from the center of the site outward, using a new sterile gauze for each pass and not returning to the center.

Question type 4: "When performing an instrument count, the post-procedure count is one sponge short of the pre-procedure count. What is the next step?" — Answer: do not allow the wound to be closed until the sponge is located or imaging (e.g., X-ray) confirms it is not in the patient.

A practical closing note

Surgical asepsis is the discipline that protects every procedure. The exam rewards the candidate who understands the principles — sterile touches sterile, the 1-inch border is unsterile, below waist level is unsterile — and applies them to every scenario. Practice setting up a sterile field in training, practicing the open gloving until it is reflex, and practicing the prep until the circular motion and the drying time are automatic.

The CCMA who owns sterile technique owns the safety of every procedure they assist with.
