False All of the following statements about the preparatory and treatment phase of environmental infection control in the treatment room are correct EXCEPT: open packs in advance of the patient's arrival to confirm that the internal chemical indicators have changed to the appropriate color All of the following statements are correct with respect to activities at the receiving and cleaning station of the central processing EXCEPT: remove any residual organic or inorganic debris wearing puncture resistant, heavy-duty utility gloves and a hard, short handled brush All of the following segments are correct with respect to respiratory hygiene/cough etiquette EXCEPT: Source control measure include educating health care personnel, patients, and visitors about the importance of: having the source person wear a particulate filter respirator All of the following are true about spatter droplets, EXCEPT: They may become suspended in air for long periods of time The highest level of aerosol and splatter emission has been shown to occur with the use of: ultrasonic scaler SARS-CoV2 may survive on hard surfaces up to: 72 hours Current CDC guidance suggests that procedures that produce high levels of aerosols, in particular those that demonstrate exposure to infectious secretions or are likely to induce coughing should be avoided, is possible.
