A client is diagnosed with a brain tumor. The nurse's assessment reveals that the client has difficulty interpreting visual stimuli.

Based on these findings, the nurse suspects injury to which lobe of the brain?

Choice A rationale

Exercise is important but should be done in a well-lit, comfortable environment. Exercising in a dark room is not specifically beneficial for migraine management and may not address trigger factors effectively.

Choice B rationale

Adequate sleep is crucial for migraine management. Advising to sleep no more than 5 hours at a time is incorrect; sufficient rest is necessary to prevent migraines.

Choice C rationale

St. John's Wort is commonly used for depression and anxiety but has no proven efficacy for migraine management. It may also interact with other medications.

Choice D rationale

Keeping a food diary helps identify dietary triggers that can lead to migraines. Tracking food intake can reveal patterns and specific triggers to avoid.

Choice E rationale

Maintaining a headache diary is important for tracking migraine frequency, duration, and potential triggers. It helps in managing and understanding the condition better.

Choice A rationale

Cerebrospinal fluid (CSF) does not produce cerebral neurotransmitters. Neurotransmitters are produced by neurons in the brain and nervous system.

Choice B rationale

CSF acts as a barrier, but its primary role is not to protect against bacteria. It provides mechanical protection and removes waste, though some antibacterial properties exist.

Choice C rationale

CSF does not act as an insulator for temperature. It primarily serves as a cushioning agent and helps maintain homeostasis, but not temperature insulation.

Choice D rationale

CSF cushions the brain and spinal cord by providing a fluid buffer that absorbs shock. It protects these structures from trauma by creating a supportive and stable environment within the cranial and spinal cavities.
