Which of the following tests would be most appropriate for the nurse to use when assessing motor function of the trigeminal nerve?
Assess dilatation of pupils with direct light.
Ask the client to differentiate between sharp and dull sensations on the client's face.
Palpates temporal and masseter muscles while client clenches teeth.
Have the client smile, frown, and wrinkle the forehead.
The Correct Answer is C
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.

Correct Answer is A
Explanation
A. Flight of ideas is characterized by a rapid and continuous flow of thoughts where the individual frequently shifts topics, often making it difficult to follow their conversation. This is commonly observed in conditions like mania or hypomania, often seen in bipolar disorder.
B. Confabulation involves fabricating or inventing stories or information to fill in gaps in memory. It is often seen in conditions affecting memory or cognition, such as Korsakoff’s syndrome or certain types of dementia.
C. Depression typically involves symptoms such as low mood, decreased energy, and lack of interest in activities, rather than rapid speech or topic shifts. The client’s accelerated pace of speech and jumping from topic to topic do not align with the characteristics of depression.
D. Schizophrenia is a broad term for a range of symptoms, including hallucinations, delusions, disorganized thinking, and impaired social functioning. While disorganized thinking can be a symptom of schizophrenia, the specific behavior described (accelerated speech and jumping topics) more specifically indicates flight of ideas, which is not exclusive to schizophrenia.
Correct Answer is A
Explanation
A. In the Mini-Cog assessment, the inability to recall the three words (which tests short-term memory) while still being able to draw a clock (which tests visuospatial skills) could suggest early cognitive impairment or dementia. Dementia often presents with deficits in memory but may retain some other cognitive functions, like drawing. The result is consistent with a possible diagnosis of dementia, especially if memory issues are noted over time.
B. A delusion is a false belief held despite evidence to the contrary. Delusions are more related to psychiatric disorders and are not primarily assessed by the Mini-Cog. The Mini-Cog does not assess for delusions but rather focuses on cognitive function.
C. Depression can affect cognitive function, sometimes resulting in difficulties with concentration, memory, and other cognitive tasks. While depression can cause cognitive symptoms, it typically presents with other signs such as changes in mood, loss of interest in activities, and changes in sleep patterns.
D. Delirium is an acute, fluctuating change in cognition and attention, often caused by an underlying medical condition, medication, or intoxication. Delirium is characterized by rapid onset and fluctuating levels of consciousness and attention, which is not consistent with the Mini-Cog results showing stable performance on the clock drawing but poor recall.
