Taste in the 1/3 posterior of your tongue is given by:

CNV

CNX

CNIX

CN VII

Answer and Explanation

The Correct Answer is C

A.   The trigeminal nerve (CN V) is primarily responsible for sensory information from the face and motor control of the muscles of mastication (chewing). It does not carry taste sensations. Instead, it is involved in sensation (e.g., touch, pain, temperature) of the face and mouth, but not taste.
B.   The vagus nerve (CN X) has various functions, including parasympathetic control of the heart, lungs, and digestive tract, and sensory and motor functions in the throat and voice box. It does contribute to taste sensation in the region of the pharynx and the epiglottis, but it is not primarily responsible for the taste sensation on the posterior third of the tongue.
C.   The glossopharyngeal nerve (CN IX) is responsible for taste sensation on the posterior one-third of the tongue. It also contributes to the sensory innervation of the pharynx and helps in the regulation of saliva production. This nerve is specifically involved in the taste perception in the back third of the tongue.
D.   The facial nerve (CN VII) provides taste sensation to the anterior two-thirds of the tongue. It also controls the muscles of facial expression and contributes to the production of saliva and tears. The facial nerve does not provide taste sensation to the posterior third of the tongue.

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.

A. Lock the fingers together and pull against each other. B. Squeeze a thigh with the opposite hand. C. Stretch the arms over the head. D. Clench the jaw tightly

Correct Answer is A

Explanation

A. This maneuver is intended to engage other muscle groups and increase overall muscle tone. It can help facilitate the patellar reflex by increasing muscle tension and sensitivity. This technique can enhance the reflex response by engaging the client in a physical action that might make the reflex more pronounced.
B. Squeezing the thigh might create discomfort or involuntary muscle contraction, which could interfere with the reflex response. It is not a recommended technique for eliciting the patellar reflex and may not have a significant effect on reflex assessment.
C. Stretching the arms over the head does not directly influence the patellar reflex. Reflexes are typically assessed in a relaxed state, and this action might not be relevant for improving the patellar reflex response.
D. Clenching the jaw might increase overall muscle tone temporarily, but it does not directly impact the patellar reflex. This technique is less likely to influence the patellar reflex compared to techniques that engage lower body muscle groups.
