What is cavitation? ✔Correct Answer-The sonic cleaners used in hospitals work via high- frequency
sound waves (usually above 20kH) to produce an effect called cavitation—tiny bubbles of vaporized
liquid that implode (rapidly collapse) and create high pressure shock waves. ... Cavitation liter- ally
sucks soil off the instrument like a vacuum.
what is ultrasonic cleaning? ✔Correct Answer-Ultrasonic cleaning uses high frequency sound
waves. Leaning with the use of ultrasonic energy is called cavitation. These sound waves generate
tiny bubbles in the solution to get into the crevices of the instruments that are impossible to clean by
other methods. The bubbles expand until they become unstable and collapse. This implosion
generates minute vacuum areas that dislodge soil.
When placing a patient in a dorsal recumbent position how should the arms be positioned?
✔Correct Answer-In the supine (Dorsal) position the arms can be at the sides with palms toward the
body. This protects the ulnar nerve and is a natural position for the upper extremities. They can be
on armboards but the boards would not be lower than the level of the table
The habit of truthfulness is expected from perioperative nurses. This habitual honesty the
perioperative nurse gives patients is known as. ✔Correct Answer-Veracity is a character trait of
habitual truthfulness.
what does Fidelity in nursing mean? ✔Correct Answer-Fidelity in nursing means that nurses must
be faithful to the promises they made as professionals to provide competent, quality care to their
patients. Justice. Justice means fairness. When nurses care for a group of patients, care must be
given equitably, fairly and justly to each individual
what 2 things should you do post-op for pts with abdominal surgery? ✔Correct Answer-Patients
with abdominal surgery tend to take shallow breaths to guard the incision. Adequate pain control
and practicing deep breathing and coughing keeps the lungs from developing atelectasis (collapse of
lung tissue and decreased volume) It's a quick step from atelectasis to pneumonia.
What is MMR? ✔Correct Answer-jaw ridigity - can see in pediatric pts/less than 25 yrs old, but can
see later in MH too
What is Hexachlorophene? ✔Correct Answer-In medicine, hexachlorophene is useful as a topical
anti-infective, anti-bacterial agent, often used in soaps and toothpaste. It is also used in agriculture
as a soil fungicide, plant bactericide, and acaricide.
This corrosive solution can quickly cause chemical burns when in contact with skin. Once diluted in
water it can be discarded by dumping it down a regular drain. ✔Correct Answer-Paracetic Acid, in
its packaged form, is corrosive and can blister the skin. However, when mixed with water it becomes
vinegar and can be discarded in the regular drainage system.
The morbidly obese patient is immediately post op Laparoscopic Ventral Hernia Repair. What's the
most immediate risk to this patient? ✔Correct Answer-Obese patients have an increased risk of
,DVT and PE. Prophylactic anticoagulant medications are frequently given. Appropriately sized IPCD
sleeves should be applied.
when surgeon asks for increase in ESU machine, first thing to do is? ✔Correct Answer-The
perioperative nurse should first assess. (always think nursing process when ready exam questions)
The first thing to investigate when there is impedance in power is the grounding pad.
Second check the pen.
Lastly swap the machine. Power settings depend on many variables. There is not a 'max setting' that
is reasonable for all tissue.
The patient has a PVC on every other heartbeat. What is this arrhythmia? ✔Correct Answer-
bigeminy
The patient has a PVC on every third heartbeat. What is this arrhythmia? ✔Correct Answer-
trigeminy
how do you treat ventricular arrhythmia? ✔Correct Answer-with medication first, can also use
cardioversion - amiodarone
when do you use amiodarone? ✔Correct Answer-This medication is used to treat certain types of
serious (possibly fatal) irregular heartbeat (such as persistent ventricular fibrillation/tachycardia). It is
used to restore normal heart rhythm and maintain a regular, steady heartbeat. Amiodarone is known
as an anti-arrhythmic drug.
treatment of ventricular tachycardia? ✔Correct Answer-1. epi
2. amiodarone
3. defib
how do you treat SVT - supraventricular tachycardia? ✔Correct Answer-1. vagal stim
2. adenosine
3. sync cardioversion
what is normal ph? ✔Correct Answer-7.35-7.45
what is normal CO2? ✔Correct Answer-35-45
what is normal HCO3? ✔Correct Answer-22-26
How should you treat a patient with a PH 7.13, CO2 80 and HCO3 30? ✔Correct Answer-The
patient needs to be ventilated or possibly receive reversal agents for sedatives if the patient is overly
sedated. - experiencing respiratory acidosis and needs to breath faster to increase o2 and decrease
the excess co2 they have in the body - not blowing off co2 fast enough bc decreased respirations
The surgeon performed a biopsy during the bronchoscopy. The specimen is appropriately prepared
and transported to the lab. After the procedure the cutting accessory and bronchoscope are
processed. What level of processing is recommended by the Spaulding Classification System?
✔Correct Answer-the biopsy forceps are a critical item. The bronchoscope is semi-critical. The
Spaulding Classification System does not address how this combination should be processed and so
AORN recommends a multidisciplinary team decide and write policy for the facility
, The Spaulding Classification system does not address how to process semi-critical items used in
conjunction with critical items. Although flexible endoscopes are categorized as semi-critical, the
cutting accessory is critical. The accessory may emerge from the distal end of the endoscope and
contact the mucosal surface as well. Thus, there are concerns about whether semi critical items
should be sterilized rather than high level disinfection. A multidisciplinary team that includes
infection prevention, endoscopy and peri-op RNs should conduct a risk assessment to determine
whether items that secondarily enter sterile tissue or the vascular system through a mucous
membrane should be sterile.
Mr. K has come to the OR for a bowel resection. His preoperative lab work shows a potassium of 2.9.
What manifestations would you expect to find? ✔Correct Answer-hypotension
manifestations = ✔Correct Answer-signs and symptoms
ectopic beats, dysrhythmias, hypotension, muscle weakness, gastric distension paralytic ileus and
urinary retention are manifestations/signs/symptoms of what? ✔Correct Answer-low potassium -
hypokalemia
vomiting and diarrhea can cause ✔Correct Answer-Vomiting and diarrhea are causes of
hypotension, not symptoms.
muscle cramping is a symptom of what? ✔Correct Answer-hypertension
what does crushing injuries do? ✔Correct Answer-The major detrimental components released
during crush injury are myoglobin and potassium. Myoglobin can collect in the kidney faster than it
can be eliminated, causing injury to the renal tubular cells, leading to acute renal failure.
why do crushing injuries cause hyperkalemia? ✔Correct Answer-Due to the damage to the cellular
membrane during a crush injury, sodium, water, and calcium rush into the cell, causing swelling,
while simultaneously potassium, myoglobin, purines, and other toxins leak out of the cells and into
the surrounding tissue. All of this is maintained inside the compressed area.
The pneumonectomy patient is being positioned on the OR table. A beanbag positioner is used. It is
most important for the surgical team to... ✔Correct Answer-Use padding at the head and feet to
maintain spinal alignment.
A pillow or other head positioner is placed under the patient's head and lower extremities to
maintain good cervical and thoracic spinal alignment. The bottom leg is flexed, and the top leg is
straight. Padding at the lateral aspect of the bottom knee and ankle also prevents pressure on the
common peroneal nerve and distal fibula.
what nerve is at risk during a pneumonectomy? ✔Correct Answer-bc the patient would be side
lying, at risk for pressure on peroneal nerve (lateral knee)
When selecting products for use in the OR the following considerations are top priority for the
Product selection team. ✔Correct Answer-Product selection should be based on a clinical trial. This
evaluation should include performance, effectiveness and efficiency but most of all patient safety.
Unexpectedly, the 16-year-old female is displaying a Wide Complex QRS on her ECG immediately
upon arrival in the OR. She is sweating and is becoming cyanotic. She has a weak rapid pulse. The
CRNA applies oxygen and opens the IV fluid to run by gravity. The nurse expects anesthesia will give
