In the United States of America one most common neuropsychological tests used is known as:
- A. Honda-Reichstaadt Neuropsychological Test Battery.
- B. Halstead-Reitan Neuropsychological Test Battery.
- C. Haeffner-Risch Neuropsychological Test Battery.
- D. Hochman-Roider Neuropsychological Test Battery.
Correct Answer: B
Rationale: The Halstead-Reitan Neuropsychological Test Battery is one of the most commonly used neuropsychological assessments in the United States. It consists of a series of tests designed to evaluate brain and nervous system functioning, including measures of cognitive, motor, and sensory abilities. This battery is particularly useful for diagnosing brain damage, assessing the severity of neurological disorders, and planning rehabilitation strategies.

A patient who is severely brain damaged has decerebrate posturing with extended extremities. In which area of the brain should the nurse suspect the patient has sustained damage?
- A. Cerebrum
- B. Brain stem
- C. Cerebellum
- D. Hypothalamus
Correct Answer: B
Rationale: Decerebrate posturing, characterized by extended extremities, indicates damage to the brainstem, particularly the midbrain or pons. The cerebrum, cerebellum, and hypothalamus are not directly associated with this type of posturing. Recognizing decerebrate posturing is critical for assessing the severity of brain injury.
Mrs. Iris is complaining of pressure in the ischial area due to the Thomas half-ring. What nursing measure would be appropriate to relieve the pressure?
- A. Wash, dry and powder the skin well
- B. Increase the weight on the rope suspending the ring
- C. Elevate the foot of the entire bed
- D. Raise the head to semi-Fowler position
Correct Answer: C
Rationale: Elevating the foot of the bed can redistribute weight and relieve pressure.
The affection of cerebellar may produce any of the following EXCEPT:
- A. nystagmus
- B. ataxia
- C. dysmetria
- D. dyspraxia
Correct Answer: D
Rationale: Dyspraxia is the correct answer because it is a disorder of motor planning and execution, typically associated with damage to the frontal or parietal lobes, rather than the cerebellum. The cerebellum is responsible for coordination, balance, and fine motor control, so its dysfunction results in ataxia, dysmetria, and nystagmus.
The trigeminal nerve
- A. Has five divisions
- B. Mandibular division is purely sensory
- C. Has its motor nucleus in the upper pons
- D. Exits the skull entirely through the foramen ovale
Correct Answer: C
Rationale: The trigeminal nerve has three divisions (ophthalmic, maxillary, mandibular) and a motor nucleus in the upper pons. The mandibular division carries both sensory and motor fibers.
Acetylcholine and norepinephrine are two well-known _________.
- A. postsynaptic receptors
- B. enzymes that rapidly inactivate neurotransmitters
- C. drugs of abuse
- D. neurotransmitters
Correct Answer: D
Rationale: Acetylcholine and norepinephrine are two well-known neurotransmitters that play critical roles in the nervous system. Acetylcholine is involved in muscle contraction, memory, and learning, while norepinephrine regulates attention, arousal, and stress responses. These neurotransmitters bind to specific receptors on postsynaptic neurons, triggering electrical signals that propagate neural communication. Their proper functioning is essential for normal brain and body activities.
