This is an excellent way to assess your progress and identify areas that need further review. There are even more questions in the question banks and mock exams on the website.
Key Points about Hyperkalaemia:
- Definition: Hyperkalaemia is a condition characterized by elevated potassium levels in the blood (serum potassium > 5.5 mmol/L). It is a medical emergency that can lead to life-threatening arrhythmias.
- Causes: Common causes include acute or chronic kidney disease, medications (e.g., potassium-sparing diuretics, ACE inhibitors), metabolic acidosis, and conditions like rhabdomyolysis or tissue breakdown.
- Symptoms: Symptoms may include muscle weakness, fatigue, palpitations, and in severe cases, cardiac arrest. It can also be asymptomatic and discovered on routine blood tests.
- Diagnosis: Diagnosis is made through blood tests showing elevated potassium levels. ECG changes (e.g., peaked T waves, prolonged PR interval) may indicate the severity of hyperkalaemia.
- Management: Management includes stabilizing the heart with calcium gluconate, shifting potassium into cells with insulin and glucose or beta-agonists, and removing potassium from the body with diuretics, ion-exchange resins, or dialysis.
- Complications: Complications include life-threatening cardiac arrhythmias, muscle paralysis, and in severe cases, sudden death if not promptly treated.
We hope you find these resources helpful and engaging as you prepare for the MSRA. Don’t forget to explore related topics in the renal section to broaden your knowledge.
