The nurse is caring for a patient who has had a stroke (brain attack). The patient is unable to understand what the nurse is saying and appears frustrated. What term should the nurse use to document this finding?
- A. Dysphagia
- B. Confusion
- C. Receptive aphasia
- D. Expressive aphasia
Correct Answer: C
Rationale: Receptive aphasia is the inability to understand spoken or written language, often resulting from damage to Wernicke's area in the brain. Dysphagia is difficulty swallowing, confusion is disorientation, and expressive aphasia is difficulty communicating verbally. Accurate documentation is essential for planning patient care.

Neurons come in which different type(s)?
- A. Sensory
- B. Motor
- C. Skeletal
- D. A and B
Correct Answer: D
Rationale: Neurons are classified into sensory neurons, which transmit information from sensory receptors to the central nervous system, and motor neurons, which carry signals from the central nervous system to muscles and glands. Skeletal refers to muscle tissue, not neuron types. Understanding these types helps explain how the nervous system processes and responds to information.
The lateral spinothalamic tract:
- A. carries fibres which terminate in the thalamus
- B. contains mainly the second-order neurones.
- C. carries fibres that carry information on temperature and pain
- D. all above
Correct Answer: D
Rationale: The lateral spinothalamic tract carries second-order neurons transmitting pain and temperature information to the thalamus. It is a critical pathway for sensory perception and is involved in relaying these sensations to higher brain centers.
Which is the most common neurotransmitter in the brain?
- A. serotonin
- B. glutamate
- C. dopamine
- D. GABA
Correct Answer: B
Rationale: Glutamate is the most abundant excitatory neurotransmitter in the brain and is involved in nearly all excitatory brain functions. It plays a key role in synaptic plasticity, learning, and memory. Glutamate binds to receptors on postsynaptic neurons, promoting the transmission of signals. However, excessive glutamate activity can lead to excitotoxicity, causing neuronal damage and contributing to conditions like stroke and neurodegenerative diseases.
Which myotome is responsible for plantar flexion of the ankle
- A. L4/5
- B. L5/S1
- C. S1/2
- D. S2/3
Correct Answer: C
Rationale: The S1 and S2 nerve roots innervate the gastrocnemius and soleus muscles, which are responsible for plantar flexion of the ankle. This is important in assessing sacral nerve root function.
Which of the following statements is true of dementia?
- A. It is a progressive neurological disease that affects the motor neurons of the nervous system.
- B. It is the general term for conditions that involve loss of memory and impaired cognition.
- C. It is an autoimmune neuromuscular disease that affects the skeletal muscles.
- D. It is the general term used to describe a cluster of symptoms including bradykinesia with rigidity or tremor.
Correct Answer: B
Rationale: Dementia is an umbrella term for a group of conditions characterized by a decline in cognitive function, including memory loss, impaired reasoning, and changes in behavior. Alzheimer's disease is the most common form of dementia, but other types include vascular dementia and Lewy body dementia.
