Protection against infection and injury

Question 6

A nurse is caring for a patient with a stage 3 pressure injury. Which of the following best describes this stage?

Accepted Answer

Full-thickness tissue loss with visible subcutaneous fat, but no exposed bone, tendon, or muscle

Question 7

Which of the following interventions is most appropriate to prevent pressure injuries in a bed-bound patient?

Accepted Answer

Cover the wound with sterile towels moistened with $$0.9\%$$ sodium chloride and notify the provider

Question 11

Which of the following best explains why excessive moisture increases the risk of skin breakdown?

Accepted Answer
