Answer to Question 1
Correct Answer: 1
Rationale 1: Stimulation of the reticular formation causes heightened alertness and arousal of the brain as a whole. Inhibition causes general drowsiness and the induction of sleep. The RAS is responsible for sleeping and wakefulness, and it performs an alerting function for the cerebral cortex.
Rationale 2: Movement needed for bathing would increase stimulation.
Rationale 3: Allowing visitors would increase stimulation.
Rationale 4: Turning on the TV would increase stimulation.

Answer to Question 2
Correct Answer: 2
Rationale 1: Blurred vision and dry mouth are common side affects of anticholinergic drugs.
Rationale 2: High amounts of glutamate can cause death of neurons, and can be the mechanism responsible for certain types of neurotoxicity.
Rationale 3: Ataxia can be a side affect of medications affecting areas of the brain that regulate coordinated movement.
Rationale 4: Tremors are occasionally a side effect of antiseizure medications.
