,What is shearing? - ANSWER✔✔-Sliding of skin and subcutaneous tissue over stationary muscle
occurs beneath the skin
Can occur in Trendelenburg position
What is friction? - ANSWER✔✔-Act of RUBBING one tissue over another tissue or surface
Can occur when patient is dragged from one surface to another without using transfer device
What are the pressure points for supine position? - ANSWER✔✔-Occiput
Scapulae
Olecranon (elbow)
Thoracic Vertebrae
Sacrum and Coccyx
Calcaneus (heel)
What are potential complications of Trendelenburg? - ANSWER✔✔-Increased intraocular and
intracranial pressure
Increased BP and cardiac output
Risk of shearing

,What are potential complications of Lithotomy? - ANSWER✔✔-Risk for decreased respiratory
function and tidal volume
Risk for acute change in vasculature volume and cardiac exertion
Potential for compartment syndrome
Risk for hyperabduction of hips
What are potential complications of Semi-Fowler/beach chair? - ANSWER✔✔-Neurovascular
bundle strain
Potenial for decreased vascular return volume
*Air embolism
What are pressure points of prone position? - ANSWER✔✔-Cheeks
Eyes (blindness)
Ears
Female breasts
Male genitalia
Knees and toes
What are potential complications of prone position? - ANSWER✔✔-Respiratory volume is
compromised because of limited anterolateral movement and potential limitation of diaphragmatic
movements

, Potential for pain during range of motion
What is the safest radiation treatment for OR and PACU staff? - ANSWER✔✔-Afterloading
radiation treatment
In the OR, a cold, unloaded, hollow plastic or metal applicator is inserted into or adjacent to the
tissues that will receive radiation. After x-ray verification of correct placement, the radiation source
is loaded into the applicator at the patient's bedside.
What happens during vasogenic shock? - ANSWER✔✔-Cardiac output decreases, the heart muscle
weakens, and venous pressure is unstable. Two examples are anaphylaxis and septic shock.
What information should be documented when using immediate use steam sterilization ("flashing")?
- ANSWER✔✔-IUSS is performed, the information to be documented includes date, time, patient
name or ID number, load contents, sterilizer identification number, cycle parameters (time,
temperature, pressure), and indicator verification (whether chemical and/or biologic)
Results of indicator are not documented
What are signs and symptoms of hypercalcemia? - ANSWER✔✔-Cardiac dysrhythmias
kidney stones
nausea and vomiting
muscle weakness
