Maintaining skin integrity would include:

Choice A: When patient is fully oriented is incorrect because it is a positive sign of recovery from a concussion. It means that the patient is aware of their person, place, time, and situation. The nurse should monitor the patient's orientation status but does not need to report it to the doctor immediately.

Choice B: Difficulty in awakening, lethargy, dizziness, confusion, irritability, anxiety are correct because they are signs of worsening brain injury or complications from a concussion. They may indicate increased intracranial pressure, bleeding, swelling, or infection in the brain. The nurse should report these symptoms to the doctor immediately and prepare for further diagnostic tests or interventions.

Choice C: When patient is easy to arouse is incorrect because it is also a positive sign of recovery from a concussion. It means that the patient responds quickly and appropriately to verbal or physical stimuli. The nurse should monitor the patient's level of consciousness but does not need to report it to the doctor immediately.

Choice D: All of the above are incorrect because only choice b) requires immediate reporting to the doctor. Choices a) and c) are normal or expected outcomes of a concussion and do not indicate any danger or complication. The nurse should use clinical judgment and follow the guidelines for concussion management and care.

Choice A: Unconsciousness, unarousable unresponsiveness is not a description of persistent vegetative state, but rather a description of coma, as it is a state of complete loss of consciousness and reflexes caused by severe brain injury.

Choice B: Devoid of cognitive function but has sleep-wake cycles is a description of persistent vegetative state, as it is a state of minimal awareness and responsiveness caused by widespread brain damage.

Choice C: Inability to move or respond except for eye movements due to a lesion affecting the pons is not a description of persistent vegetative state, but rather a description of locked-in syndrome, as it is a state of complete paralysis and preserved consciousness caused by damage to the brainstem.

Choice D: Unresponsiveness to the environment, makes no movement or sound but sometimes opens eyes is not a description of persistent vegetative state, but rather a description of akinetic mutism, as it is a state of severe apathy and reduced motor activity caused by damage to the frontal lobes or basal ganglia.
