After a car accident, Rhodri had a lot of difficulty planning his day. This is most likely the result of damage to which lobe?
- A. temporal
- B. parietal
- C. frontal
- D. occipital
Correct Answer: C
Rationale: The frontal lobe is responsible for executive functions, such as planning, decision-making, and problem-solving. Damage to the frontal lobe, as might occur in a car accident, can impair these abilities, making it difficult for individuals to organize tasks, set goals, or manage time. The frontal lobe also plays a role in personality, social behavior, and motor control, highlighting its importance in complex cognitive processes.

The nurse is preparing material about impulse transmission to help with a presentation on the neurological system. When discussing spinal nerves, the nurse will include that each spinal nerve is made up of the dorsal root and which other root?
- A. Medial
- B. Lateral
- C. Ventral
- D. Proximal
Correct Answer: C
Rationale: Each spinal nerve has two roots: the dorsal root, which carries sensory impulses into the spinal cord, and the ventral root, which carries motor impulses away from the spinal cord. The medial, lateral, and proximal roots are not part of the spinal nerve structure. Understanding this anatomy is essential for explaining how sensory and motor functions are integrated.
Fibrillations (fasciculations) may develop with disease in:
- A. lateral column of the spinal cord
- B. posterior horn of the spinal cord
- C. anterior horn of the spinal cord
- D. internal capsule
Correct Answer: C
Rationale: Anterior horn of the spinal cord is the correct answer because fibrillations and fasciculations are spontaneous muscle contractions that occur due to the degeneration of lower motor neurons located in the anterior horn. These contractions are a sign of denervation and are commonly seen in conditions like amyotrophic lateral sclerosis (ALS).
