Week 3 NCLEX Readiness: Physiological Adaptation Part 2: NR 446 / NR446 (Latest Update 2025 / 2026) Collaborative Healthcare | 77 Comprehensive Questions & Answers | Grade A | 100% Correct – Chamberlain: Quiz_________________? What is the most clinically significant risk associated with hyperkalemia? - Answer☑️ ️⚡ "It messes with the heartbeat!" Changes in cardiac conduction Impaired cardiac depolarization Quiz_________________? What EKG change is commonly seen with severe hyperkalemia? - Answer☑️ Tall, peaked T waves A classic and early sign of high potassium Quiz_________________? What happens to the P wave in hyperkalemia? - Answer☑️ It may disappear! Loss of P wave is a sign of worsening conduction issues Quiz_________________? What EKG interval is prolonged with hyperkalemia? - Answer☑️ Prolonged PR interval = delayed AV conduction Quiz_________________? What happens to the ST segment in hyperkalemia? - Answer☑️ Seen with severe electrolyte imbalances like hyperkalemia Quiz_________________? What happens to the QRS complex in hyperkalemia? - Answer☑️ Widened QRS = dangerous slowing of ventricular conduction Quiz_________________? What are key signs and symptoms of hypokalemia? - Answer☑️ "Low K = low muscle + rhythm mess!" Cardiac rhythm abnormalities (e.g., arrhythmias) Nausea Vomiting Diarrhea Quiz_________________? Why is hypokalemia dangerous for the heart? - Answer☑️ ️ "Potassium keeps the beat!" Low K⁺ = irregular rhythms, especially in clients on digoxin or with cardiac history Quiz_________________? Why is a client with NG suction at high risk for hypokalemia? - Answer☑️ "Suction pulls potassium!" NG suction = loss of GI fluids rich in potassium Leads to hypokalemia (< 3.5 mEq/L) Quiz_________________? What is hypokalemia defined as? - Answer☑️ Serum potassium less than 3.5 mEq/L Can cause cardiac, GI, and neuromuscular symptoms Quiz_________________? What are the most common causes of hypokalemia? - Answer☑️ "Potassium escapes!" GI losses: vomiting, diarrhea, laxatives, ileostomy Kidney losses: diuretics (especially loop/thiazide) Quiz_________________? What non-GI, non-renal conditions can cause hypokalemia? - Answer☑️ "Shift shockers!" DKA treatment (K⁺ shifts into cells) Stress (catecholamine surge) Coronary ischemia Quiz_________________? What are early neuromuscular signs of hypocalcemia? - Answer☑️ "Nerves on edge!" Numbness & tingling (especially around mouth and extremities) Muscle cramps Hyperreflexia Quiz_________________? What are hallmark physical signs of hypocalcemia? - Answer☑️ "Say hi with Chvostek, wave with Trousseau!" Chvostek's sign: facial twitch with cheek tap Trousseau's sign: carpal spasm with BP cuff inflation Quiz_________________? How does hypocalcemia affect mental status and mood? - Answer☑️ Depression Irritability Confusion Fatigue and weakness Quiz_________________? What are severe complications of hypocalcemia? - Answer☑️ Laryngeal/bronchial spasms (airway risk!) Tetany Seizures
