Which combination of symptoms is commonly associated with dehydration and may indicate the need for urgent management?

• A. Seizures, cardiac dysrhythmias, nausea/vomiting (N/V)
• B. Headache and dizziness
• C. Severe edema and weight gain
• D. Fever and rash

Answer: (A)

Severe dehydration disrupts both circulating volume and electrolyte balance, so it can lead to serious CNS and cardiac problems that demand urgent care. Seizures can result from extreme electrolyte disturbances (such as extreme sodium shifts) and reduced brain perfusion. Cardiac dysrhythmias arise from imbalances in potassium, magnesium, and calcium during fluid loss, compounded by poor perfusion. Nausea and vomiting are common with dehydration and reflect ongoing losses and electrolyte disruption. Together, these symptoms point to dehydration at a level that requires rapid assessment and fluid/electrolyte management. Headache and dizziness can occur with dehydration but aren’t as specific or alarming; severe edema and weight gain suggest fluid overload, not dehydration; fever and rash aren’t typical signs of dehydration.
