A nurse is caring for a client admitted with dehydration suspected to have an electrolyte imbalance. Which finding should the nurse identify as a possible cause of electrolyte imbalance?
Clostridium difficile infection
Parkinson's disease
Asthma
Hypertension
The Correct Answer is A
Choice A reason:
Clostridium difficile infection commonly causes severe diarrhea, which can lead to excessive loss of fluids and electrolytes such as sodium, potassium, and bicarbonate. This fluid and electrolyte loss significantly increases the risk of dehydration and electrolyte imbalance, making it the most likely cause.
Choice B reason:
Parkinson's disease is a neurological disorder that affects movement and motor control. While it may indirectly impact nutrition or hydration in advanced stages, it is not a direct or common cause of acute electrolyte imbalance associated with dehydration.
Choice C reason:
Asthma primarily affects the respiratory system and does not typically cause significant fluid or electrolyte losses. Unless complicated by other factors, asthma alone is unlikely to result in dehydration-related electrolyte imbalance.
Choice D reason:
Hypertension is a chronic cardiovascular condition characterized by elevated blood pressure. By itself, it does not directly cause dehydration or electrolyte imbalance unless influenced by factors such as diuretic use, which are not specified in the question.

Correct Answer is A
Explanation
Choice A reason:
Influenza is an acute viral illness that primarily affects the respiratory system. Complications such as pneumonia, hypoxia, and respiratory distress are common and can become life-threatening if not identified promptly. According to priority principles, airway and breathing take precedence, making respiratory assessment the nurse’s first priority.
Choice B reason:
Neurological assessment may be necessary if the client shows signs of altered mental status or complications such as encephalopathy. However, neurological involvement is not the primary or most immediate concern in uncomplicated influenza, so it does not take priority over respiratory assessment.
Choice C reason:
The endocrine system is not directly impacted in the acute phase of influenza. While systemic illness can affect metabolic demands, endocrine assessment is not urgent compared to respiratory function in this condition.
Choice D reason:
Cardiovascular assessment is important for overall monitoring, especially in older adults or those with comorbidities. However, influenza most commonly compromises oxygenation and ventilation first, so respiratory assessment remains the highest priority.
Correct Answer is A
Explanation
Choice A reason:
Delegation allows a nurse to assign tasks to appropriate team members based on their scope of practice while maintaining accountability for outcomes. Proper delegation improves workflow efficiency, ensuring timely, safe, and effective care for clients.
Choice B reason:
Although the person performing the task carries responsibility for completing it correctly, the nurse who delegates retains overall accountability for client outcomes. Delegation does not remove the nurse’s accountability.
Choice C reason:
Delegation is not primarily intended to reduce cost; it focuses on safe and efficient delivery of care. While it may have cost benefits, this is a secondary outcome rather than a defining characteristic.
Choice D reason:
Delegation is not about assigning tasks a nurse does not want to perform. It must be based on client needs, staff competency, and legal scope of practice, not personal preference.
