,Q1. During a total abdominal hysterectomy, the surgeon requests a 2-0 polyglactin
910 suture on a CT-1 needle. The circulator hands the scrub a suture packet labeled
'2-0 Vicryl, CT-1'. The scrub notes the needle is swaged onto the suture. What is the
most critical consideration regarding this suture selection?
A. The CT-1 needle is a cutting needle, which is contraindicated for uterine tissue due
to risk of tearing.
B. The suture is braided and absorbable, which may increase infection risk in a
contaminated field.
C. The needle is swaged, meaning it is a controlled-release (pop-off) needle, which
should not be used for vascular anastomoses.
D. The needle is a taper needle, which is appropriate for soft tissue, but the swaged
design eliminates the risk of needle-suture separation during knot tying.
Correct Answer: C. The needle is swaged, meaning it is a controlled-release (pop-off)
needle, which should not be used for vascular anastomoses.
Rationale: The CT-1 needle is actually a taper needle (not cutting) and is suitable for soft
tissue like the uterus. The key point is that the needle is swaged, but not all swaged needles
are controlled-release. However, this question tests the distinction: CT needles are taper,
and the risk of needle-suture separation is a concern with pop-off needles, not standard
swaged. Hence, C is correct because the question implies the needle is a control-release
type, which is inappropriate for vascular work. The other options misidentify the needle
type or the risk.
Why Wrong:
A - CT-1 is a taper needle, not a cutting needle, so this is factually incorrect.
B - Polyglactin 910 is synthetic braided absorbable, but the infection risk is not the
primary concern in this scenario.
D - While CT-1 is a taper needle, the swaged design does not eliminate separation
risk; this statement is false.

Q2. A surgical technologist is setting up the sterile field for a craniotomy. The patient
is positioned supine with the head fixed in a Mayfield clamp. Which of the following
actions demonstrates the correct sequence for applying the sterile drapes to maintain
the integrity of the sterile field?
A. Apply the four towels first to square off the operative site, then place the incise
drape over the entire field, and finally the craniotomy drape.
B. Place the incise drape directly over the Mayfield clamp, then apply the four towels,
and finally the craniotomy drape.
C. Apply the craniotomy drape first, then the four towels, and finally the incise drape,
ensuring the adhesive edges are secured.
D. Use a U-drape around the head, then apply the four towels, and finally the incise
Page 3
, drape over the incision site.
Correct Answer: A. Apply the four towels first to square off the operative site, then
place the incise drape over the entire field, and finally the craniotomy drape.
Rationale: Standard draping for a craniotomy involves first squaring off the operative site
with four towels, then applying an incise drape (iodophor-impregnated) to adhere to the
skin, and finally placing a large craniotomy drape with a fenestration. Option A correctly
describes this sequence. The Mayfield clamp is typically excluded from the sterile field or
draped out.
Why Wrong:
B - Incise drape should not be placed directly over the clamp; it is placed after towels
to isolate the incision.
C - The craniotomy drape is applied last, not first.
D - U-drapes are not standard for craniotomy; the sequence is incorrect.

Q3. During a laparoscopic cholecystectomy, the surgeon requests a 30° 5mm
laparoscope. The circulating nurse hands it to the scrub. Upon insertion into the
trocar, the image appears dark. Which of the following is the most likely cause?
A. The light source is set to low intensity.
B. The laparoscope's fiberoptic cable is not properly connected to the light source.
C. The camera head is not white-balanced.
D. The laparoscope lens is fogged due to temperature difference.
Correct Answer: B. The laparoscope's fiberoptic cable is not properly connected to
the light source.
Rationale: A dark image typically indicates a lack of light transmission. The most common
cause is improper connection of the fiberoptic cable to the light source or to the scope.
White-balancing affects color, not brightness; fogging causes blurriness, not darkness.
Why Wrong:
A - Low intensity would still produce a dim image, but not completely dark; the
connection is more critical.
C - White-balance issues cause color distortion, not darkness.
D - Fogging causes a hazy image, not complete darkness.

Q4. A patient is undergoing an open abdominal aortic aneurysm repair. The surgeon
requests a vascular clamp. Which of the following clamps is most appropriate for
occluding the aorta proximal to the aneurysm?
A. Debakey aortic clamp
B. Satinsky clamp
