Final answer:
Suctioning for a patient who had a stroke 6 hr ago and who is at risk for ICP should be limited to 10 seconds.
Step-by-step explanation:
When suctioning a patient who had a stroke and is at risk for intracranial pressure (ICP), it is important to minimize the time suction is applied in order to prevent an increase in ICP. The recommended time limit for suctioning in this case is 10 seconds (Option 1). This helps to minimize the risk of oxygen deprivation to the brain and potential complications.
