A nurse is caring for a client in an induced coma for increased intracranial pressure (ICP). What should the nurse assess next to determine this client's cerebral function?
Glasgow Coma Scale
Pupillary size and reaction
Blood pressure and heart rate
Gag Reflex
The Correct Answer is B
A. The Glasgow Coma Scale is useful for assessing consciousness levels but may not be as sensitive for changes in brainstem function in a patient already in an induced coma.
B. Assessing pupillary size and reaction provides critical information on brainstem function and can indicate changes in ICP. Changes in pupil size and reaction can signify worsening cerebral function or brain herniation.
C. Blood pressure and heart rate are vital signs that can suggest increased ICP, but they are not as direct an indicator of cerebral function as pupil assessment.
D. The gag reflex is important but does not provide as direct information about cerebral function related to ICP as pupillary assessment does.

Correct Answer is C
Explanation
A. While chlorine can kill some bacteria, it does not prevent all microbial growth and does not directly explain ear infections.
B. Pool water entering the Eustachian tubes is unlikely; infections are more commonly related to pathogens in the water.
C. The best response addresses the presence of microorganisms in pool water that can enter the ear and potentially lead to infections, such as swimmer's ear (otitis externa).
D. Pool water is not typically associated with drying out the ears; rather, it can lead to excess moisture, which can promote bacterial growth.
Correct Answer is B
Explanation
A. While monitoring serum electrolytes is important, it is secondary to assessing for immediate life-threatening conditions.
B. Monitoring for signs of shock is the priority, as Addisonian crisis can lead to severe hypotension and shock, which requires immediate intervention.
C. Monitoring daily weights can help assess fluid status but is not critical in the context of an impending crisis.
D. Monitoring intake and output is important for overall assessment but does not directly address the immediate risks associated with Addisonian crisis.
