Which behaviors by the patient diagnosed with a chronic head injury would the nurse expect to find?

Being increasingly non-compliant with therapeutic care plans.

Playing chess with fellow patients within one week of admission.

Difficulty planning and organizing thoughts and behaviors.

Ability to process multiple pieces of information at the same time.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Chronic head injuries can impair judgment, leading to non-compliance with care plans due to reduced awareness and impulse control. However, non-compliance alone is not a definitive behavioral characteristic of chronic head injury.

Choice B rationale

Rapid engagement in cognitively demanding tasks like chess within a week suggests intact neurological and cognitive function, which contradicts the expected deficits in chronic head injury patients.

Choice C rationale

Chronic head injuries commonly affect the frontal lobe, impairing executive functions such as planning, organizing, and controlling thoughts and behaviors. These deficits result from damage to neural pathways crucial for these cognitive tasks.

Choice D rationale

The ability to process multiple pieces of information simultaneously requires intact cognitive functioning, typically disrupted in chronic head injuries due to neuronal damage, particularly in the prefrontal cortex.

Correct Answer is D

Explanation

Choice A rationale

Hypertension is not the primary concern in cervical spinal cord injuries at C-3, where respiratory compromise due to diaphragm paralysis is the leading cause of complications or mortality.

Choice B rationale

Bradycardia can occur due to vagal stimulation in spinal injuries but is less life-threatening compared to the respiratory compromise caused by diaphragmatic paralysis.

Choice C rationale

Sepsis may develop in spinal cord injury patients, particularly from infections like pneumonia or urinary tract infections, but respiratory failure is the most acute concern at C-3.

Choice D rationale

Respiratory compromise occurs due to impaired diaphragm function at C-3, making it the primary cause of morbidity or mortality, necessitating prompt respiratory support and monitoring.

A. A patient who was in an assault resulting in basilar skull fracture. B. A patient who was found face down in water for an unknown length of time. C. A patient who suffered an epidural or subdural hematoma. D. A patient who experienced prolonged seizures without regaining consciousness.

Correct Answer is B

Explanation

Choice A rationale

Basilar skull fractures can lead to cerebral injuries and CSF leaks, but do not typically cause anoxic brain injury unless they compromise oxygenation or cause cerebral edema severely reducing blood flow.

Choice B rationale

Prolonged submersion compromises oxygen delivery, leading to diffuse cerebral hypoxia or anoxia, the primary cause of brain injury in drowning victims due to interruption of arterial oxygenation over unknown durations.

Choice C rationale

Epidural or subdural hematomas elevate intracranial pressure and compress brain tissue, but they are not as immediately hypoxic as situations involving complete oxygen deprivation like submersion.

Choice D rationale

Prolonged seizures, or status epilepticus, may disrupt normal metabolic processes, potentially causing neuronal injury. However, primary hypoxia is generally less pronounced than in submersion cases.
