The job of the Nervous System is:
- A. to receive stimulus as sensory input.
- B. integration of stimulus with reaction.
- C. to trigger action as a motor response or motor output.
- D. All of the above.
Correct Answer: D
Rationale: The nervous system performs three primary functions: receiving sensory input, integrating and processing this input, and triggering motor responses. Sensory input involves detecting stimuli from the environment or within the body. Integration occurs in the brain and spinal cord, where information is processed. Motor output involves sending signals to muscles or glands to produce a response. Therefore, the nervous system's job encompasses all these functions, making 'All of the above' the correct answer.

What advice must the nurse give to prevent recurrence of insect bites?
- A. Prevent strenuous exercises by the client when outdoors.
- B. Apply insect repellant to clothing and exposed skin.
- C. Wear thick woolen clothing to cover the skin while outdoors.
- D. Avoid giving daily baths to the client with soaps.

Rationale: Insect repellants are effective in preventing bites.
What are the two branches of the autonomic nervous system?
- A. endocrine and exocrine
- B. upper and lower
- C. sympathetic and parasympathetic
- D. central and peripheral
Correct Answer: C
Rationale: The autonomic nervous system (ANS) regulates involuntary bodily functions and is divided into the sympathetic nervous system, which activates the 'fight or flight' response, and the parasympathetic nervous system, which promotes 'rest and digest' activities. These two branches work in opposition to maintain homeostasis.
During the physical assessment of the patient with early to moderate RA, what should the nurse expect to find?
- A. Hepatomegaly
- B. Heberden's nodes
- C. Spindle-shaped fingers
- D. Crepitus on joint movement
Correct Answer: C
Rationale: Spindle-shaped fingers are characteristic of RA.
Testosterone is to ________ as estrogen is to ________.
- A. thyroid, parathyroid
- B. testes, ovaries
- C. sympathetic, parasympathetic
- D. pancreas, pituitary
Correct Answer: B
Rationale: Testosterone is primarily produced by the testes in males, while estrogen is primarily produced by the ovaries in females. Both hormones play crucial roles in reproductive development and function. Testosterone is associated with male secondary sexual characteristics, such as muscle mass and facial hair, while estrogen regulates the menstrual cycle and female secondary sexual characteristics. These hormones also have broader effects on mood, bone density, and overall health.
Which type of fiber could be considered the longest?
- A. preganglionic parasympathetic
- B. preganglionic sympathetic
- C. postganglionic parasympathetic
- D. postganglionic sympathetic
Correct Answer: A
Rationale: The correct answer is A: preganglionic parasympathetic. Preganglionic fibers are the longest in the autonomic nervous system, with parasympathetic fibers generally having longer preganglionic fibers compared to sympathetic fibers. Parasympathetic preganglionic fibers originate from the cranial nerves and sacral spinal cord, allowing them to travel longer distances to reach their ganglia. In contrast, sympathetic preganglionic fibers originate from the thoracic and lumbar spinal cord, resulting in shorter lengths compared to parasympathetic fibers. Therefore, preganglionic parasympathetic fibers are considered the longest among the given choices. Postganglionic fibers, whether parasympathetic or sympathetic, are shorter as they only need to travel to their target organs from the ganglia.
Summary:
- A: Correct, as preganglionic parasympathetic fibers are the longest in the autonomic nervous system
