The nurse notes that a patient has a history of falling. Which part of the brain should the nurse question as being affected in this patient?
- A. Medulla
- B. Cerebellum
- C. Frontal lobes
- D. Hypothalamus
Correct Answer: B
Rationale: The cerebellum is responsible for coordination, balance, and posture, making it the most likely area affected in a patient with a history of falling. The medulla regulates vital functions, the frontal lobes control voluntary movement, and the hypothalamus maintains homeostasis. The cerebellum's role in motor control is essential for assessing balance issues.
The presence of ptosis suggests damage to cranial nerve:
- A. IV
- B. V
- C. III
- D. VII
Correct Answer: C
Rationale: Cranial nerve III (oculomotor nerve) is the correct answer because it innervates the levator palpebrae superioris muscle, which is responsible for elevating the eyelid. Damage to this nerve results in ptosis, or drooping of the eyelid, along with other symptoms such as diplopia and impaired eye movement.
