Minor Surgery Procedures and Medical Assistant Roles in Clinical Settings
Q1. A medical assistant (MA) is preparing a patient for a minor surgical procedure in an
outpatient clinic. Which of the following tasks is within the MA's legal scope of practice in
most states, assuming appropriate training and delegation?
A) Incising and draining a small abscess
B) Administering local anesthesia (e.g., lidocaine) independently
C) Suturing a simple laceration
D) Setting up the sterile field and handing instruments to the provider
E) Interpreting pathology results for the patient
Detailed Answer:
Correct Answer: D
Medical assistants are trained in sterile technique and can set up a sterile field, prepare
instruments, and hand them to the provider (assisting during procedures). Incision and drainage
(A), suturing (C), and administering local anesthesia (B) are generally outside the MA scope and
must be performed by a licensed provider (physician, PA, or NP) depending on state law.
Interpreting pathology (E) is the provider's duty.
Q2. A patient is scheduled for a minor excision of a skin lesion. The medical assistant is
responsible for obtaining informed consent. Which of the following is the MA's primary role
in the consent process?
A) Explaining the risks and benefits of the procedure in detail
B) Answering all clinical questions about the procedure
C) Witnessing the patient's signature on the consent form
D) Deciding if the patient is competent to consent
E) Administering pre-procedure sedation
Detailed Answer:
Correct Answer: C
The MA's role in informed consent is to witness the patient's signature on the consent form,
ensuring the patient is signing voluntarily and that the form is complete. Explaining risks and
benefits (A) and answering clinical questions (B) are the provider's responsibility. The provider
determines competency (D). Sedation (E) is not an MA role.
Q3. A medical assistant is preparing an examination room for a minor surgical procedure.
Which of the following is the correct sequence for preparing the sterile field?
A) Open the sterile pack, put on sterile gloves, place drapes, arrange instruments
,B) Put on sterile gloves, open the sterile pack, arrange instruments, place drapes
C) Place drapes, open sterile pack, put on sterile gloves, arrange instruments
D) Put on sterile gloves, place drapes, open sterile pack, arrange instruments
E) Open sterile pack, place drapes, put on sterile gloves, arrange instruments
Detailed Answer:
Correct Answer: A
The correct sequence is: (1) Open the sterile pack on a clean, dry surface (without touching the
inside), (2) Put on sterile gloves, (3) Place sterile drapes around the surgical site, (4) Arrange
sterile instruments on the sterile field. You must be gloved before touching any sterile items.
Q4. A patient asks the medical assistant about the difference between "sterile" and "clean"
technique. The MA's most accurate response is:
A) Sterile technique is used for all minor procedures; clean technique is used for wound care.
B) Sterile technique removes all microorganisms; clean technique reduces the number of
microorganisms.
C) Sterile technique uses alcohol; clean technique uses soap and water.
D) Both are the same; they are interchangeable terms.
E) Sterile technique is for surgery; clean technique is for injections.
Detailed Answer:
Correct Answer: B
Sterile technique (aseptic technique) aims to eliminate all microorganisms (including spores)
from instruments, gloves, and the field. Clean technique (medical asepsis) reduces the number
of microorganisms and prevents their spread but does not eliminate them entirely. Clean
technique is used for routine tasks like wound care, but minor surgery requires sterile
technique. The other answers are incorrect simplifications.
Q5. A medical assistant is performing a surgical hand scrub before a minor procedure. The
minimum duration for an acceptable surgical hand scrub (using an antimicrobial agent) is
generally:
A) 30 seconds
B) 1 minute
C) 2–3 minutes
D) 5–7 minutes
E) 10 minutes
,Detailed Answer:
Correct Answer: C
For a surgical hand scrub (as opposed to a routine hand wash), the recommended duration is 2–
3 minutes for the initial scrub of the day, and 1–2 minutes for subsequent scrubs, depending on
the product. The traditional 5–7 minute scrub (D) is outdated; the current standard is 2–3
minutes with an antimicrobial agent.
Q6. A medical assistant is asked to assist with a punch biopsy. Which of the following is the
MA's most appropriate role during the procedure?
A) Holding the skin taut with a forceps while the provider uses the punch
B) Applying the local anesthetic injection
C) Removing the specimen and placing it in formalin
D) Suturing the biopsy site
E) Interpreting the pathology report
Detailed Answer:
Correct Answer: A
The MA's role in a punch biopsy is to assist the provider by holding the skin taut (with a forceps
or fingers) to stabilize the tissue while the provider performs the punch. The provider applies
local anesthetic (B), removes the specimen (C), and sutures the site (D). The MA may hand
instruments and manage the specimen after the provider has removed it.
Q7. A medical assistant is preparing a tray for a minor surgical procedure. Which of the
following is NOT part of a standard minor surgery tray?
A) Needle holder
B) Scalpel handle with blade
C) Adson forceps
D) Bone rongeur
E) Suture scissors
Detailed Answer:
Correct Answer: D
A minor surgery tray typically includes a scalpel, needle holder, Adson or DeBakey forceps,
suture scissors, hemostats, and sometimes skin hooks or retractors. A bone rongeur (D) is an
orthopedic/neurosurgical instrument used for cutting bone and is not part of a standard minor
soft-tissue tray.
, Q8. A patient has a minor wound that requires a simple interrupted suture. The medical
assistant is preparing the suture material. Which of the following is the most commonly used
suture size for skin closure in minor surgery?
A) 6-0
B) 5-0
C) 4-0
D) 2-0
E) 1-0
Detailed Answer:
Correct Answer: C
4-0 (or 3-0) is the most commonly used suture size for skin closure in minor surgery on the
trunk or extremities. 5-0 (B) is used on the face. 6-0 (A) is for microsurgery or delicate areas. 2-0
(D) and 1-0 (E) are for deep tissues, fascia, or heavy wounds.
Q9. A medical assistant is documenting a minor procedure in the patient's chart. Which of the
following elements is essential for proper documentation?
A) The patient's blood pressure before and after
B) The name of the provider performing the procedure
C) The type and amount of local anesthetic used
D) The number of sutures placed
E) All of the above
Detailed Answer:
Correct Answer: E
Documentation for a minor procedure should include: the procedure performed, the provider,
the anesthetic (type, amount, and time), the site, the condition of the wound, the number of
sutures, any complications, the patient's vital signs before and after, and the post-procedure
instructions. All are essential.
Q10. A medical assistant is asked to dispose of a scalpel blade after a minor procedure. Which
of the following is the correct method for safe disposal?
A) Place the blade in a regular trash can
B) Recap the blade and place it in the sharps container
