Which action would be beneficial to a patient with a right brain stroke?

A. Wear shoes when out of bed B. Arrange food on the left side C. Remove clutter and obstacles D. Give directions nonverbally

Correct Answer: C

Rationale: Right-brain strokes impair spatial awareness; removing clutter prevents falls. B aids vision loss, not universal. [Level: Application]

Multipolar neurons have:

A. One dendrite and one axon B. Multiple dendrites and one axon C. One dendrite and multiple axons D. Multiple dendrites and multiple axons

Correct Answer: B

Rationale: Multipolar neurons have many dendrites and one axon, typical of motor neurons. [Level: Knowledge]

The rapid depolarization phase of an action potential is primarily due to:

A. Outward movement of potassium ions B. Inward movement of sodium ions C. Inward movement of chloride ions D. Activation of calcium channels

Correct Answer: B

Rationale: Na+ influx causes depolarization, making the inside positive. [Level: Knowledge]

In an electrical synapse, direct communication between neurons occurs through structures known as:

A. Synaptic vesicles B. Gap junctions C. Reuptake transporters D. Neurotransmitter receptors

Correct Answer: B

Rationale: Gap junctions allow direct ion flow in electrical synapses, bypassing chemical steps. [Level: Knowledge]

Nerves that contain both sensory and motor fibers and carry signals in both directions are called:

A. Afferent nerves B. Efferent nerves C. Mixed nerves D. Interneurons

Correct Answer: C

Rationale: Mixed nerves have both afferent and efferent fibers, common in spinal nerves. [Level: Knowledge]
