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.
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 B
Explanation
Choice A rationale
Administering oxygen at 6 liters per minute via nasal cannula risks hypercapnia in a client with emphysema due to impaired CO2 elimination. Oxygen should be titrated to maintain safe saturation levels, usually 88–92%.
Choice B rationale
Ipratropium is a bronchodilator that safely alleviates airway constriction in emphysema without systemic cardiovascular effects, making it suitable for a client with coronary artery disease and chronic obstructive pulmonary conditions.
Choice C rationale
Propranolol is contraindicated in emphysema due to its beta-blocking effects, which may exacerbate bronchoconstriction and reduce respiratory function, posing a significant risk to the client’s health.
Choice D rationale
Organic herbal supplements lack evidence-based safety and efficacy, especially in complex medical conditions like coronary artery disease and emphysema. They can also interact adversely with prescribed medications.
Correct Answer is A
Explanation
Choice A rationale
Brown-Sequard injury results in ipsilateral motor function loss due to corticospinal tract damage and contralateral pain/temperature loss from spinothalamic tract disruption, characteristic of this hemisection spinal cord injury.
Choice B rationale
Central cord injury affects cervical spine and hand function but does not exhibit hemisection symptoms like ipsilateral motor loss or contralateral sensory loss. Symptoms vary and commonly include upper limb weakness.
Choice C rationale
Posterior cord injury primarily impacts dorsal column function, resulting in loss of proprioception and vibration sense. Motor and pain/temperature functions are preserved, unlike in Brown-Sequard injury.
Choice D rationale
Anterior cord injury involves ischemic damage to the anterior spinal artery, leading to motor paralysis and pain/temperature loss bilaterally, not ipsilateral and contralateral as described in the question.
