A nurse is caring for a client with a history of hypertension who presents with a severe headache and blurred vision. What is the most likely cause of these symptoms?

Choice A rationale
Septic shock is a severe infection leading to systemic inflammation, characterized by high fever (39°C), low blood pressure (90/60 mmHg), and signs of organ dysfunction. It is a medical emergency requiring immediate intervention.
Choice B rationale
Cardiogenic shock is caused by the heart’s inability to pump blood effectively, leading to hypotension and signs of poor perfusion, but not necessarily high fever.
Choice C rationale
Neurogenic shock results from a disruption in the autonomic pathways, leading to hypotension and bradycardia, but not high fever.
Choice D rationale
Anaphylactic shock is a severe allergic reaction causing hypotension, respiratory distress, and other symptoms, but not typically high fever.

Choice A rationale
Hypokalemia can cause muscle weakness and cramps, but it does not typically lead to severe muscle spasms causing exhaustion. The patient’s symptoms of lethargy and weakness are more likely related to electrolyte imbalances and dehydration rather than muscle spasms.
Choice B rationale
While low potassium levels can affect cellular metabolism, the primary issue here is not glycolysis. The patient’s symptoms are more consistent with dehydration and electrolyte imbalances rather than a metabolic shift to glycolysis.
Choice C rationale
Hypokalemia can cause cells to become hyperpolarized, leading to muscle weakness and decreased reflexes. However, the patient’s symptoms of lethargy and weakness are more likely due to dehydration and electrolyte imbalances rather than cellular hyperpolarization.
Choice D rationale
Hypernatremia, or high sodium levels, can cause cellular dehydration, leading to symptoms such as lethargy and weakness. The patient’s lab results and clinical presentation are consistent with hypernatremia-induced cellular dehydration, which explains his symptoms.
