CSFA EXAM B PRACTICE QUESTIONS AND
DETAILED SOLUTIONS
◉ A wound that is known to be infected at the time of surgery and is
left open to be closed at a later date is categorized as.
Answer: delayed primary closure
Wound closure is delayed or secondary for the purpose of walling off
an area of gross infection or where extensive tissue was removed.
The edges are closed 4-6 days postoperatively after meticulous
debridement.
◉ A long-term complication of a cemented total hip arthroplasty is.
Answer: loosening of the prosthesis
◉ When performing compression hip screw fixation, the lag screw is
inserted.
Answer: within 1 cm of the femoral articular surface.
◉ After receiving a preoperative epidural catheter, a patient is given
a bolus of local anesthetic intraoperatively. The patient then
demonstrates signs of hypotension and complete respiratory failure.
Which of the following is the MOST likely cause?.
Answer: migration of the epidural catheter through the dura
, With patient movement, the epidural catheter may migrate through
the dura. A bolus injection into the subdural space can cause total
spinal anesthesia resulting in hypotension and respiratory failure.
◉ The main consideration in surgical needle selection is.
Answer: to minimize trauma
◉ During a posterolateral approach to the hip, which of the
following structures usually found superficially to the obturator and
gemelli should be identified and protected?.
Answer: sciatic nerve
The sciatic nerve (largest nerve in the body) arises from the
lumbosacral plexus. It emerges from the pelvis below the piriformis
and enters the thigh between the ischial tuberosity and the greater
trochanter.
◉ Tetralogy of Fallot includes which defects?.
Answer: Ventricular septal defect, pulmonary valve stenosis, right
ventricular hypertrophy, and transposition of the aorta are the four
anomalies that comprise Tetralogy of Fallot.
◉ Pulling on the wrist to reduce a radius fracture incorporates
which of the following principles of surgical assisting?.
Answer: traction/counter traction
,◉ If a Kelly clamp is left in a patient who underwent a
cholecystectomy, which of the following legal charges can be filed?.
Answer: Res ipsa loquitur (or the thing speaks for itself) is a
doctrine that applies to injuries sustained by a patient while in the
OR
◉ During a posterolateral approach for an intracapsular hip fracture,
which of the following muscles would be released along with the
short external rotators and capsule from the posterior aspect of the
femur as a single musculocapsular flap?.
Answer: The piriformis muscle arises from the sacrum and inserts at
the highest point on the greater trochanter. It is an extensor and
lateral rotator of the femur
◉ The gluteus medius.
Answer: inserts on the greater trochanter of the femur. Under the
medius is the gluteus minimus. It inserts anteriorly on the greater
trochanter.
◉ The superior and inferior gemelli and obturator internus.
Answer: are found between the piriformis and quadratus femoris.
They insert along the upper border of the greater trochanter.
◉ The quadratus femoris.
, Answer: inserts on the trochanteric crest of the femur.
◉ When an open appendectomy is performed, it is necessary to
identify the.
Answer: cecum and ileocecal valve
◉ In patients who develop fever, abdominal pain, and profuse
diarrhea, the MOST frequently seen antibiotic-associated
enterocolitis is due to which of the following organisms?.
Answer: C diff
◉ Clostridium difficile.
Answer: a species that causes watery diarrhea, fever, anorexia, and
abdominal pain, sometimes accompanied by pseudomembranous
colitis, especially in patients previously treated with antibiotics or
confined in healthcare settings. Most antibiotics (except
aminoglycosides) have been associated with the development of C.
difficile-associated disease, which varies in clinical significance from
a relatively mild diarrheal illness to one complicated by dehydration,
electrolyte disturbances, toxic megacolon, and death.
◉ Pseudomonas aeruginosa.
Answer: a species that produces a distinctive blue-green pigment,
grows readily in water, and may cause life-threatening infections in
humans, including nosocomial pneumonia, urinary tract infections,
