To elicit a Plantar reflex:
- A. Gently tap the Achilles tendon
- B. Stroke the lateral aspect of the sole of the foot from heel to ball
- C. Present a noxious odor to a person
- D. Observe the person walking heel to toe
Correct Answer: B
Rationale: The Plantar reflex is elicited by stroking the lateral aspect of the sole of the foot from the heel to the ball of the foot with a blunt object. This tests the integrity of the corticospinal tract. A normal response in adults is plantar flexion of the toes.

The brain and spinal cord are the organs of the ________ .
- A. CNS
- B. PNS
- C. ANS
- D. CSF
Correct Answer: A
Rationale: The brain and spinal cord are the primary organs of the central nervous system (CNS). The CNS is responsible for processing and integrating information received from the peripheral nervous system (PNS). The autonomic nervous system (ANS) is a division of the PNS, and cerebrospinal fluid (CSF) is a protective fluid surrounding the CNS. Therefore, CNS is the correct answer as it directly refers to the brain and spinal cord.
Following administration of 1.5 g of methocarbamol (Robaxin), which of the following statements by Mrs. Iris would inform the nurse that the medication was effective?
- A. I was thirsty after that medication.
- B. I have been urinating a lot today.
- C. Those awful muscle spasms have let up.

Which part of the limbic system is involved in an animal's feeling of hunger?
- A. thalamus
- B. pons
- C. hippocampus
- D. hypothalamus
Correct Answer: D
Rationale: The hypothalamus is a key part of the limbic system and is involved in regulating hunger, thirst, and other homeostatic processes. It receives signals from the body about energy needs and releases hormones that stimulate or suppress appetite. The hypothalamus also plays a role in regulating the autonomic nervous system and maintaining the body's internal balance. Its involvement in hunger highlights its importance in survival and behavior.
What does an abnormal response in the assessment of the plantar reflex indicate?
- A. Possible neurological dysfunction, such as an upper motor neuron lesion.
- B. Normal reflex response.
- C. Absence of reflex abnormalities.
- D. Clear, coordinated movements.
Correct Answer: A
Rationale: An abnormal plantar reflex, such as toe extension (Babinski sign), suggests possible upper motor neuron dysfunction. A normal reflex involves toe flexion.
The anal reflex mainly depends on which segment
- A. S1
- B. S2
- C. S3
- D. S4
Correct Answer: C
