In initial stage of Parkinson disease the most typical involuntary movement is the following:
- A. chorea
- B. atetosis
- C. tremor
- D. dystonia
Correct Answer: C
Rationale: Tremor is the correct answer because it is one of the earliest and most characteristic symptoms of Parkinson's disease. The tremor is typically a resting tremor, which decreases with voluntary movement and is often described as ‘pill-rolling' due to its appearance. It results from the degeneration of dopaminergic neurons in the substantia nigra.

Injury to which segment of the spine results in damage to the chest and abdominal muscles?
- A. cervical
- B. thoracic
- C. lumbar
- D. sacral
Correct Answer: B
Rationale: Injury to the thoracic spine (T1-T12) can affect the chest and abdominal muscles, as this region of the spinal cord controls motor and sensory functions for the upper body. Damage here can lead to paralysis or weakness in these areas.
What central fiber tract connects forebrain and brain stem structures with the hypothalamus?
- A. cardiac accelerator nerve
- B. medial forebrain bundle
- C. dorsal longitudinal fasciculus
- D. corticospinal tract
Correct Answer: B
Rationale: The correct answer is B: medial forebrain bundle. This tract connects the forebrain and brain stem structures with the hypothalamus, playing a crucial role in regulating various physiological functions. It is involved in the control of emotions, reward pathways, and feeding behaviors. The other choices are incorrect because: A) cardiac accelerator nerve is involved in regulating heart rate, not connecting forebrain structures with the hypothalamus; C) dorsal longitudinal fasciculus is associated with eye movements and visual processing, not connecting forebrain with the hypothalamus; D) corticospinal tract is responsible for voluntary motor movements, not involved in connecting forebrain structures with the hypothalamus.
What best describes the manifestations of OA?
- A. Smaller joints are typically affected first.
- B. There is joint stiffness after periods of inactivity.
- C. Joint stiffness is accompanied by fatigue, anorexia, and weight loss.
- D. Pain and immobility may be aggravated by falling barometric pressure.
Correct Answer: B
Rationale: OA stiffness occurs after inactivity.
Which of the following nursing interventions may reduce hemostasis and decrease the potential for thrombophlebitis for a client with neurologic disorder?
- A. Remove and reapply elastic stockings
- B. Change the client's position
- C. Keep extremities at neutral position
- D. Use a flotation mattress
Correct Answer: B
Rationale: Changing position promotes circulation and reduces clot formation.
Which statement accurately describes dementia?

- B. Dementia resulting from neurodegenerative causes can be prevented.
- C. Dementia caused by hepatic or renal encephalopathy cannot be reversed.
