The nurse places a coin in the patient's hand, the patient is with eyes closed. The ability to identify an object by feeling it is defined as:

Extinction

Stereognosis

Proprioception

Two-point discrimination

Answer and Explanation

The Correct Answer is B

A.   Extinction refers to the phenomenon where a person fails to recognize a stimulus on one side of the body when another stimulus is presented simultaneously on the opposite side. This is often tested in cases of neurological impairment, particularly in the context of sensory neglect or loss
B.   Stereognosis is the ability to identify an object by touch and proprioception without visual input. It involves recognizing the shape, size, and texture of an object solely through tactile information. Placing a coin in the patient’s hand and asking them to identify it with their eyes closed tests their ability to use tactile information to recognize objects, making stereognosis the correct term for this assessment.
C.   Proprioception is the sense of the position and movement of the body and its parts. It involves awareness of body position in space, which is crucial for coordination and balance. While important, proprioception does not specifically involve identifying objects by touch alone; it is more about the awareness of body position.
D.   Two-point discrimination is the ability to distinguish between two closely spaced points of contact on the skin. It tests the sensitivity of the skin to touch and is often used to assess sensory nerve function. It does not involve identifying objects by touch but rather measuring how well one can discern between two separate points of contact.

Correct Answer is C

Explanation

A. This test assesses the function of the oculomotor nerve (CN III), not the trigeminal nerve. The oculomotor nerve controls the constriction and dilation of the pupils, as well as some eye movements. Therefore, this choice is not appropriate for assessing the trigeminal nerve.
B. This test assesses the sensory function of the trigeminal nerve (CN V). The trigeminal nerve provides sensation to the face, and testing the ability to differentiate between sharp and dull sensations evaluates

the sensory component of this nerve. However, this test does not assess the motor function of the trigeminal nerve.
C. This test evaluates the motor function of the trigeminal nerve. The trigeminal nerve controls the muscles involved in chewing, including the temporal and masseter muscles. By palpating these muscles while the client clenches their teeth, the nurse assesses the strength and function of these muscles, which are innervated by the trigeminal nerve. This is a direct test of motor function for CN V.
D. This test assesses the function of the facial nerve (CN VII), which controls the muscles of facial expression. It is not relevant for assessing the trigeminal nerve, which is involved in both sensory functions of the face and motor functions related to chewing.

A. perseveration B. flight of ideas C. derailment D. confabulation E. negative Babinski reflex

Correct Answer is D

Explanation

A. Perseveration refers to the repetition of a particular response or behavior despite the cessation of the stimulus that prompted it. This often occurs in individuals with neurological disorders, where they keep repeating the same word, phrase, or action.
B. Flight of ideas is a rapid flow of thoughts where the person moves quickly from one topic to another, often with tangential or disconnected ideas. It is commonly observed in conditions such as mania or hypomania.
C. Derailment, also known as loosening of associations, is a thought disorder where a person’s speech goes off-topic and seems disorganized. The connections between ideas are loose or fragmented, making the conversation difficult to follow.
D. Confabulation is a memory disturbance where a person creates false memories or fabricated details to fill in gaps in their memory. The individual does not intentionally deceive but genuinely believes their fabricated information is true.
