Choice A rationale:

Environmental cleaning before suctioning is crucial to maintain a clean and safe environment for the patient. This reduces the risk of introducing additional contaminants during the procedure.

Choice B rationale:

Using a reusable suctioning catheter is not appropriate for infection control measures. Reusable catheters can harbor microorganisms, even after proper cleaning and sterilization, increasing the risk of cross-contamination.

Choice C rationale:

Proper disposal of used catheters into a regular trash bin is not a suitable infection control measure. Used catheters should be disposed of in designated biohazard containers to prevent exposure to potential pathogens.

Choice D rationale:

Hand hygiene before and after the procedure is essential to reduce the transmission of microorganisms to and from the patient.

Choice E rationale:

Wearing gloves and a mask during suctioning helps protect the nurse from exposure to the patient's bodily fluids and potential infectious agents.

Repeat steps 7 to 9 until no more secretions are obtained or until three passes are completed. Do not suction more than three times in a row to prevent complications. Allow at least one minute of rest between each suction pass to prevent fatigue and distress .
