patient - ANSWER 1. pathogen transmittal
2. portal of entry into the susceptible host
3. invasion of a susceptible host
Which of the following tendon autografts is MOST typically utilized when performing
anterior cruciate ligament (ACL) reconstruction? - ANSWER patellar tendone
What is the normal range of red blood cells in a complete blood count for an adult
male? - ANSWER 4.6-6.2 x 106/nl
Which of the following organisms normally found on the skin can cause wound
infections? - ANSWER (c) B. Staphylococcus aureus, often simply referred to as "staph,"
is commonly found on the skin and in the nose.
Which of the following is the desired effect when applying a partially threaded
cancellous screw to a bone fragment - ANSWER compression
When transferring a thoracotomy patient to recovery, the chest drainage system should
be - ANSWER below the patient's chest level
Which of the following bones make up the pelvic girdle? - ANSWER coccyx, sacrum, os
coxae
,During a carotid endarterectomy, the arteries are unclamped and reclamped before
arteriotomy closure is performed to - ANSWER to flush debris from the carotid
Injury to which of the following arteries is commonly seen in the temporal lobes, where
the skull is the thinnest and meningeal blood vessels are numerous, and is the usual
cause of epidural hematomas? - ANSWER middle meningeal
Epidural hematoma is typically caused by trauma in the middle meningeal artery. A
linear fracture of the squamous portion of the temporal bone can tear the middle
meningeal.
During arterial cannulation in cardiopulmonary bypass (CPB), the cannula tip must be
directed into which of the following arteries? - ANSWER The cannula tip is placed into
the ascending aorta and provides blood flow downstream away from the heart.
Which of the following is an example of a high-level disinfecting agent? - ANSWER
glutaraldehyde
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, and sepsis. It may also cause
