Question 80: What happens when the blood-brain barrier is compromised?

Harmful substances can enter the brain, causing damage (Correct answer)
It improves the brain's ability to repair itself.
The brain becomes more sensitive to light.
The brain becomes more resilient.

Correct answer: Harmful substances can enter the brain, causing damage

The blood-brain barrier is a highly selective semipermeable membrane that separates circulating blood from the brain and extracellular fluid in the central nervous system. Its primary function is to protect the brain from pathogens, toxins, and harmful chemicals. When this barrier is compromised, it loses its protective integrity, allowing potentially damaging substances to enter the delicate brain tissue, which can lead to inflammation, infection, or neurological damage.

Question 91: What is the goal of physical therapy for patients with neurological disorders?

To reduce stress.
To improve mobility and strength (Correct answer)
To encourage weight loss.
To monitor heart rate.

Correct answer: To improve mobility and strength

Physical therapy for neurological disorders focuses on restoring and improving physical function that may be impaired due to nerve damage or brain conditions. Therapists work with patients to enhance their balance, coordination, strength, and range of motion, ultimately aiming to improve their ability to perform daily activities and increase independence.

Question 92: Which is the best way to position a patient with increased intracranial pressure?

Flat supine with knees flexed
HOB 30 degrees with the head midline (Correct answer)
Prone with the neck flexed
Trendelenburg

Correct answer: HOB 30 degrees with the head midline

Raising the head of bed to 30 degrees with the head midline helps venous drainage and lowers ICP.
