Final answer:
A CNA should not ensure that restraints are very tight so the patient does not escape; they should be secure but not impede circulation or cause injury.
Step-by-step explanation:
When a doctor orders a patient to be placed in restraints, the CNA should NOT ensure that the restraints are very tight so the patient does not escape. It is essential that restraints are used safely and ethically, ensuring that they do not cause harm or unnecessary discomfort to the patient. In addition to providing toileting and water as needed, and checking on the patient regularly, the CNA must also ensure that restraints are secure but not so tight as to impede circulation or cause injury. Furthermore, restraints should be tied to an unbreakable part of the bed frame that allows for some movement, rather than directly to the bed frame which could cause harm if the bed is moved or adjusted.
