AND ANSWERS
◉ the MOST important considerations when preventing wound
infection in the surgical 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?.
