Pressure Sore Prevention and Management

The video tutorial discusses the prevention of pressure sores, focusing on shearing forces and their impact on patients in bed and sitting positions. It explains reactive hyperemia, the role of pressure and time in sore development, and the effects of different surfaces. The tutorial emphasizes the importance of regular observation and patient repositioning to prevent pressure sores.

What is one method to prevent a patient from sliding down the bed?

• Keeping the bed at a flat angle

• Placing a pillow under the knees

• Using a hard board under the back

• Using a slippery mattress cover

What is the effect of a soft pillow under the calf muscles?

• It causes more pressure sores

• It distributes pressure evenly

• It is not recommended under any circumstances

• It increases the risk of DVT

What does reactive hyperemia indicate?

• A sign of infection

• A decrease in blood supply

• An increase in blood supply after pressure is relieved

• A permanent damage to the skin

What happens to tissues when pressure is applied and then relieved?

• They become infected

• They lose all blood supply

• They experience reactive hyperemia

• They become permanently damaged

Which surface exerts the highest pressure on the sacrum?

• Feather pillows

• Foam mattress

• Hard linoleum floor

• Sprung mattress

What is the critical pressure threshold for capillary occlusion?

• 75 millimeters of mercury

• 50 millimeters of mercury

• 15 millimeters of mercury

• 25 millimeters of mercury

Which mattress type showed the lowest pressure on the sacrum?

• Feather pillows

• Foam mattress

• Sprung mattress

• Hard linoleum floor

How can pressure sores develop according to the pressure-time relationship?

• By high pressure for short periods or low pressure for long periods

• By any pressure for any period

• Only by high pressure for long periods

• Only by low pressure for short periods

What is the relationship between pressure and time in pressure sore formation?

• Both high pressure and long time can cause sores

• Only high pressure causes sores

• Only long time causes sores

• Neither pressure nor time affects sore formation

What is a key role of nurses in preventing pressure sores?

• Applying ointments regularly

• Using only hard surfaces for support

• Preventing pressure and shearing forces

• Ensuring patients remain immobile
