Asepsis & Infection Control
An infection acquired while a patient is receiving care in a hospital or medical facility.
What is a nosocomial infection?
A person who has completed the surgical scrub but is not wearing a sterile gown uses this method to put on sterile gloves.
What is open gloving?
This part of a ring-handled surgical instrument locks the instrument in the closed position.
What is the ratchet?
This component controls the amount of oxygen flowing through the anesthesia machine.
What is the flowmeter?
Surgical patients are commonly fasted before anesthesia to reduce the risk of this serious complication if they regurgitate.
What is aspiration pneumonia?
This monitor measures the electrical activity traveling through the heart.
What is an ECG/electrocardiogram?
The surgical term -ectomy means this.
What is surgical removal?
This dental instrument measures gingival pocket depth in millimeters.
What is a periodontal probe?
This process destroys most harmful microorganisms on an inanimate object but does not reliably destroy all microbial life.
What is disinfection?
During surgery, the sterile portion of the gown includes the arms and this area of the front of the gown.
What is the area from the waist to the neck?
Unlike an Olsen-Hegar, this needle holder does not have built-in scissors.
What is a Mayo-Hegar needle holder?
This component converts liquid anesthetic into a vapor so it can be delivered to the patient.
What is the vaporizer?
Because anesthetized patients do not blink normally, this should be applied to protect their eyes during surgery
What is eye lubricant?
An anesthetized patient has an SpO₂ of 91%. This value indicates a problem because the desired SpO₂ is above this percentage.
What is 95%?
This post-operative complication occurs when a surgical incision opens because the wound edges or sutures fail prematurely.
What is dehiscence?
This part of the tooth contains its nerves and blood vessels.
What is the pulp?
A contaminated instrument introduces bacteria into a surgical incision. The instrument is considered this type of contamination source because the organisms came from outside the patie
What is an exogenous source?
A scrubbed assistant finishes helping with the drapes and has nothing in their hands. This is where their hands should be kept to maintain sterility.
What is between waist and shoulder level?
This lubricating solution helps maintain surgical instruments after cleaning and should be changed weekly or bi-weekly.
What is instrument milk?
This system removes waste anesthetic gases to reduce exposure to personnel.
What is the scavenger system?
After an endotracheal tube is placed and secured, this is inflated to create a seal within the trachea.
What is the ET tube cuff?
During anesthesia, a patient’s MAP drops to 54 mmHg. This is below the minimum acceptable MAP of this value.
What is 60 mmHg?
After the vaporizer is turned off, the patient remains on 100% oxygen for several minutes for this reason.
What is to flush remaining anesthetic gases from the lungs?
In the Triadan numbering system, the first digit identifies this information about the tooth.
What is the quadrant?
A disinfectant works poorly because it was wiped off almost immediately after application. This factor affecting pathogen destruction was inadequate.
What is contact time?
A surgical assistant accidentally lowers their sterile hands below waist level while repositioning at the table. What must they assume about their gloves?
What is they are contaminated?
When preparing instruments for an autoclave pack, ratcheted instruments should be left in this position so steam can reach all surfaces.
What is unlocked/open?
During manual ventilation, the pressure on this gauge should never exceed 20 cm H₂O.
What is the manometer?
A patient is clipped, initially scrubbed, induced, and moved into the surgical suite. Before the procedure begins, this should already be running to help prevent a common anesthetic complication.
What is the patient heating device?
An anesthetized dog has a respiratory rate of 7 breaths/minute. Based on the expected anesthetized range, is this value too low, too high, or acceptable?
What is acceptable?
A recovering patient has pale mucous membranes and an increased respiratory rate. These findings should raise concern for this post-operative complication
What is internal bleeding?
During a dental extraction, the tooth has already been loosened with an elevator. This instrument is then used to remove the tooth from its socket.
What are extraction forceps?
Name two factors that determine whether contamination will result in infection.
What are any two: patient health, tissue damage, pathogen virulence, or number of pathogens?
A sterile assistant turns their back to the sterile field. The field must now be considered this.
What is contaminated?
A delicate item needs to be sterilized but cannot tolerate the high temperatures used during steam sterilization. This sterilization method may be selected instead.
What is ethylene oxide gas sterilization?
A 10-lb cat and a 50-lb dog are being prepared for anesthesia. Which patient should be placed on a rebreathing circuit?
What is the 50-lb dog?
A patient’s ET tube is removed while the cuff is still inflated. This structure is at risk of injury.
What is the trachea?
During surgery, the patient’s eyes are rotated ventrally. This eye position is associated with this desired plane of anesthesia.
What is moderate anesthesia depth?
A patient recovering from anesthesia is a brachycephalic breed. Compared with many other patients, this patient should undergo this airway-management change during recovery
What is delayed extubation?
A mandibular tooth surface is described as facing toward the tongue. This directional term should be recorded in the dental chart.
What is lingual?
