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 ["10"]
Explanation
To calculate the dose of valproic acid oral solution, the nurse should use the following formula:
Dose (mL) = Ordered dose (mg) / Concentration (mg/mL) x Volume (mL)
Plugging in the values from the question, we get:
Dose (mL) = 500 mg / (250 mg / 5 mL) x 5 mL
Simplifying, we get:
Dose (mL) = 500 mg / 50 mg x 5 mL
Dose (mL) = 10 mL
Therefore, the nurse should administer 10 of valproic acid oral solution to the patient.
Correct Answer is C
Explanation
A. Perform passive range of motion on each extremity:
While passive range of motion exercises are important for preventing contractures and maintaining joint mobility in immobilized clients, they are not the highest priority in this situation. Airway management takes precedence over mobility exercises.
B. Monitor the client's electrolyte levels:
Monitoring electrolyte levels is important for overall assessment and management of the client's health, but it is not the highest priority when the client's airway and breathing are compromised.
C. Suction saliva from the client's mouth:
This is the correct answer. Suctioning saliva from the client's mouth helps maintain a clear airway and prevents aspiration. Unconscious clients are at risk for pooling of oral secretions, which can obstruct the airway and lead to respiratory complications.
D. Record the client's intake and output:
While monitoring intake and output is an essential part of nursing care, it is not the highest priority when the client's airway and breathing are compromised.
