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 A
Explanation
A. The client should maintain systolic BP between 120 and 129 mm Hg.
This is an appropriate recommendation. The American Heart Association (AHA) guidelines recommend maintaining systolic BP below 130 mm Hg to reduce the risk of stroke and other cardiovascular events in individuals with a history of stroke or TIA.
B. The client should maintain systolic BP between 130 and 135 mm Hg.
This is slightly above the recommended range. While systolic BP below 135 mm Hg is generally recommended for individuals with a history of stroke or TIA, a range of 130-135 mm Hg may still be acceptable based on individual patient factors and risk assessments.
C. The client should maintain systolic BP between 136 and 140 mm Hg.
This is above the recommended range. Systolic BP between 136 and 140 mm Hg may be considered elevated and should be managed to lower levels to reduce the risk of recurrent TIA or stroke.
D. The client should maintain systolic BP between 141 and 145 mm Hg.
This is above the recommended range. Systolic BP above 140 mm Hg is generally considered elevated and should be managed to lower levels to reduce the risk of recurrent TIA or stroke.
Correct Answer is ["15"]
Explanation
To calculate the dose of amantadine for a client with parkinsonism, the nurse needs to use the following formula:
Dose (mL) = Ordered dose (mg) / Concentration (mg/mL).
In this case, the ordered dose is 150 mg and the concentration is 50 mg/5 mL. Therefore, the dose in mL is:
Dose (mL) = 150 mg / (50 mg/5 mL)
Dose (mL) = 150 mg x (5 mL/50 mg)
Dose (mL) = 15 mL
The nurse should round the answer to the nearest whole number, which is 15 mL. The nurse should administer 15 mL of amantadine oral solution to the client.
