Poukisa Potasyòm Se Elektwolit ki pi Danjere a

Why Potassium Is the Deadliest Electrolyte

🍌 Twò piti epi kè a tranble. Twòp epi li kanpe. Potasyòm letal nan de bout yon entèval nòmal ki etwat, epi li se youn nan chif yo teste plis nan egzamen an.

🍌 Too little and the heart quivers. Too much and it stops. Potassium is lethal at both ends of a narrow normal range, and it is one of the most tested numbers on the exam.

💡 Ide prensipal

T pwenti vle di wo: calcium, insulin ak dextrose, retire li. Onn U vle di ba: ranplase li dousman, pa janm pouse li.

Peaked T means high: calcium, insulin and dextrose, remove it. U waves mean low: replace slowly, never push.

🧠 Poukisa sa enpòtan

Nòmal la se 3.5 rive 5.0 mEq/L. Potasyòm WO bay gwo onn T pwenti ak yon QRS k ap elaji; trete kè a an premye ak calcium gluconate, aprè sa deplase potasyòm nan antre nan selil yo ak insulin ak dextrose, aprè sa retire li ak lyan oswa dyaliz. Potasyòm BA bay onn T plat ak onn U, feblès ak yon sansiblite danjere pou digoxin; ranplase li pa bouch oswa ak ponp a pa plis pase anviwon 10 mEq pa èdtan nan venn periferik. Pa janm, nan okenn sikonstans, pouse li IV.

Normal is 3.5 to 5.0 mEq/L. HIGH potassium gives tall peaked T waves and a widening QRS; treat the heart first with calcium gluconate, then shift potassium into cells with insulin and dextrose, then remove it with binders or dialysis. LOW potassium gives flat T waves and U waves, weakness and dangerous digoxin sensitivity; replace it by mouth or by pump at no more than about 10 mEq per hour peripherally. Never, under any circumstances, IV push.

🏥 Nan lavi reyèl

💉 Yon enfimyè te resevwa yon lòd pou 'KCl 20 mEq IV' epi li te tire li nan yon sereng. Apèl telefòn famasyen an te sove yon lavi. Yo te retire potasyòm konsantre nan pifò inite yo pou rezon sa a menm, epi egzamen an ap kontinye mande jiskaske chak enfimyè konnen poukisa.

💉 A nurse once received an order for 'KCl 20 mEq IV' and drew it into a syringe. The pharmacist's phone call saved a life. Concentrated potassium has been removed from most units for exactly this reason, and the exam will keep asking until every nurse knows why.

📌 Sa pou retni

  • 3.5 rive 5.0; toude direksyon lakòz aritmi3.5 to 5.0; both directions cause arrhythmias
  • Wo: calcium gluconate pwoteje, insulin ak dextrose deplase, dyaliz retireHigh: calcium gluconate protects, insulin and dextrose shift, dialysis removes
  • Ba: siveye pasyan digoxin yo; pa janm pouse IVLow: watch digoxin clients; never IV push

Ki chanjman ECG ki siyal ipèkalemi?Which ECG change signals hyperkalemia?
  1. Gwo onn T pwentiTall peaked T waves
  2. Yon entèval PR rakousiA shortened PR interval
  3. Elevasyon STST elevation
  4. Onn T aplati ak onn UFlattened T waves with U waves

Repons: A · Gwo onn T pwenti

Onn T pwenti se premye siy ECG potasyòm wo; onn T plat ak onn U endike potasyòm ba.

Peaked T waves are the earliest ECG sign of high potassium; flat T waves and U waves point to low potassium.

Yon enfimyè resevwa yon lòd pou potassium chloride IV push. Ki aksyon ki kòrèk?A nurse receives an order for potassium chloride IV push. What is the correct action?
  1. Bay li sou 5 minitGive it over 5 minutes
  2. Dilye li nan 10 mL epi pouse li dousmanDilute it in 10 mL and push slowly
  3. Kesyonnen lòd laQuestion the order
  4. Bay li sèlman nan yon liy santralGive it only through a central line

Repons: C · Kesyonnen lòd la

Yo pa janm bay potasyòm IV push, nan okenn liy ni a okenn vitès: li ka lakòz arè kadyak. Yo toujou dilye li epi enfize li ak ponp a yon vitès kontwole.

Potassium is never given IV push, through any line or at any speed: it can cause cardiac arrest. It is always diluted and infused by pump at a controlled rate.
