An acute care nurse is caring for an adult client who is undergoing evaluation for a possible brain tumor. While performing a neurological examination, which of following findings is the earliest indicator of the client's cerebral status?
Pupil response
Deep tendon reflexes
Muscle strength
Level of consciousness
The Correct Answer is D
A. Pupil response:
Pupil response refers to the reaction of the pupils to light stimulus. The pupils should normally constrict when exposed to bright light and dilate in dim light. Changes in pupil size or reactivity can indicate alterations in neurological function. For example, unequal or non-reactive pupils (anisocoria or fixed pupils) can be indicative of dysfunction in the cranial nerves or brainstem. However, while pupil response is an important aspect of neurological assessment, it may not always be the earliest indicator of cerebral status changes.
B. Deep tendon reflexes:
Deep tendon reflexes are involuntary muscle contractions in response to stretching of a muscle tendon. These reflexes are assessed by tapping the tendon with a reflex hammer, eliciting a rapid and brief muscle contraction. Changes in deep tendon reflexes can provide information about the integrity of the peripheral nervous system and spinal cord. However, alterations in deep tendon reflexes may occur secondary to changes in cerebral function and are typically assessed along with other neurological signs.
C. Muscle strength:
Muscle strength refers to the force generated by muscles during voluntary movement. It is typically assessed by asking the client to perform specific movements against resistance or by testing the strength of individual muscle groups using standardized scales (e.g., Medical Research Council scale). Changes in muscle strength can occur due to neurological or musculoskeletal conditions. While weakness or paralysis can result from lesions affecting the upper motor neurons (e.g., strokes or spinal cord injuries), alterations in muscle strength may not always be the earliest indicator of cerebral status changes.
D. Level of consciousness:
The level of consciousness refers to the degree of awareness and alertness exhibited by the client. It is assessed by evaluating the client's responsiveness, orientation, and ability to follow commands. Changes in the level of consciousness, such as confusion, lethargy, stupor, or coma, can indicate alterations in cerebral function and are often the earliest indicators of neurological dysfunction. Assessing the level of consciousness is a critical component of neurological examination and helps guide further assessment and management of clients with suspected brain tumors or other neurological conditions.

Correct Answer is C
Explanation
A. Increased blinking
Increased blinking is not a typical manifestation of bradykinesia. In fact, individuals with Parkinson's disease may experience reduced blinking (hypokinesia of blinking) rather than increased blinking.
B. States of euphoria
Euphoria is not typically associated with bradykinesia. Instead, individuals with Parkinson's disease may experience a range of mood changes, including depression, anxiety, or apathy, but euphoria is not a common finding.
C. Slurred speech
This is the correct answer. Slurred speech, or dysarthria, can occur in individuals with Parkinson's disease as a result of bradykinesia affecting the muscles involved in speech production. Bradykinesia can cause a reduction in the speed and coordination of movements necessary for clear speech, resulting in slurred or mumbled speech patterns.
D. Decreased respiratory rate
Decreased respiratory rate is not typically associated with bradykinesia. Bradykinesia primarily affects voluntary movements rather than involuntary processes such as respiration. While respiratory muscle weakness can occur in advanced stages of Parkinson's disease, it is not directly related to bradykinesia.
Correct Answer is C
Explanation
A. Check the client for a fecal impaction.
This intervention is important for managing autonomic dysreflexia because a fecal impaction can trigger autonomic dysreflexia by causing rectal distention. However, it is not the first action the nurse should take. Promptly addressing the immediate cause of autonomic dysreflexia is crucial to prevent complications.
B. Ensure the room temperature is warm.
This intervention is important for maintaining the client's comfort and preventing temperature-related complications. However, it is not the first action the nurse should take when suspecting autonomic dysreflexia. Immediate interventions to address the underlying cause of autonomic dysreflexia are necessary to prevent serious complications such as stroke or seizure.
C. Check the client's bladder for distention.
This is the correct action to take first. Bladder distention is one of the most common triggers of autonomic dysreflexia in individuals with spinal cord injuries. A distended bladder stimulates autonomic reflexes, leading to a sudden increase in blood pressure. Therefore, the nurse should assess the client's bladder for distention and initiate appropriate interventions such as catheterization to relieve urinary retention.
D. Raise the head of the bed.
While elevating the head of the bed can help reduce blood pressure in some situations, it is not the first action the nurse should take when suspecting autonomic dysreflexia. Elevating the head of the bed may exacerbate autonomic dysreflexia by increasing venous return and blood pressure. Therefore, addressing the underlying cause of autonomic dysreflexia, such as bladder distention, takes priority.
