The emergency room nurse is caring for an adolescent who briefly lost consciousness following a collision with another player on the soccer field. Which sign is concerning? Select all that apply.

Patient's pupillary reaction is sluggish

Patient asks "Where am I?"

Patient successfully performs the finger-nose-finger test

Patient states "At least we won the game!"

Patient has a positive Romberg test

Answer and Explanation

Correct Answer : A,B,E

A. Patient's pupillary reaction is sluggish: A delayed or unequal pupillary response to light suggests increasing intracranial pressure or damage to the cranial nerves. This is a critical indicator of potential cerebral edema or intracranial hemorrhage following a head injury. Normal pupils should be briskly reactive to light (PERRLA).

B. Patient asks "Where am I?": Disorientation to place or time is a hallmark of a concussion or more severe traumatic brain injury. It indicates an impairment of cognitive processing and memory, which are vital parameters in neurological monitoring. Confusion following a loss of consciousness necessitates a higher level of clinical surveillance.

C. Patient successfully performs the finger-nose-finger test: This result indicates intact cerebellar function and good coordination, which is a reassuring finding during a neurological exam. Successful completion of this test suggests that the motor pathways and cerebellum are currently functioning normally. It is not a concerning sign in the context of head trauma.

D. Patient states "At least we won the game!": This statement demonstrates that the patient has retained recent memory and is capable of forming coherent sentences. It shows an awareness of the event's context and suggests that long-term and immediate recall may be intact. This is a positive sign of cognitive orientation.

E. Patient has a positive Romberg test: A positive result, indicated by a loss of balance when the eyes are closed, suggests vestibular or proprioceptive dysfunction. This finding is highly concerning after a head collision, as it may indicate a concussion or injury to the equilibrium centers. It highlights a significant deficit in neurological stability.

Correct Answer is A

Explanation

A. Hold hands back-to-back while flexing the wrists to 90 degrees for 60 seconds: This position increases pressure within the carpal tunnel and compresses the median nerve against the flexor retinaculum. The test is considered positive if the patient experiences numbness or tingling in the median nerve distribution. It is a specific diagnostic maneuver for entrapment.

B. Press the palms together for 2-3 seconds: This action does not provide the necessary mechanical compression of the median nerve required for a provocative neurological test. Brief palm pressing lacks the specific anatomical positioning needed to elicit symptoms of nerve compression. It is not a recognized maneuver for carpal tunnel.

C. Interlace the metacarpals for 2-3 seconds: Interlacing the fingers or metacarpals does not put the carpal tunnel under sufficient stress to reproduce neurological symptoms. This movement does not target the median nerve at the wrist joint. It is an irrelevant action for diagnosing upper extremity nerve entrapment syndromes.

D. Internally rotate the shoulders, pressing the hands into the back: This movement assesses the internal rotation of the glenohumeral joint and the integrity of the rotator cuff. It has no diagnostic value for conditions affecting the distal upper extremity or the median nerve. It is used for shoulder rather than wrist evaluations.

A. Difficulty understanding speech B. Impaired ability to sense touch, vibration, positioning C. New onset vision changes D. Frequent emotional outbursts

Correct Answer is D

Explanation

A. Difficulty understanding speech: This deficit, known as Wernicke's aphasia, typically results from lesions in the temporal lobe of the dominant hemisphere. It involves an inability to process auditory language despite intact hearing. The frontal lobe manages motor speech production via Broca's area rather than language comprehension.

B. Impaired ability to sense touch, vibration, positioning: These sensory modalities are primarily processed in the postcentral gyrus of the parietal lobe. Damage to this somatosensory cortex disrupts the perception of tactile and proprioceptive stimuli. The frontal lobe is primarily dedicated to motor execution and higher-order executive functions.

C. New onset vision changes: The primary visual cortex and visual association areas are located within the occipital lobe at the posterior of the brain. Injuries to this region result in visual field deficits or cortical blindness. Frontal lobe pathology does not typically present with primary sensory visual disturbances.

D. Frequent emotional outbursts: The prefrontal cortex of the frontal lobe regulates personality, social behavior, and impulse control. Damage to this region often leads to disinhibition, emotional lability, and significant alterations in temperament. It is the anatomical center for executive decision-making and emotional regulation.
