a chemical element, atomic number 19, atomic weight 39.102.
Potassium supplements are never given to patients receiving potassium-sparing Homeostatic balance of potassium.
Through the functions of resorption and excretion, the kidneys are the best regulator of potassium balance in the extracellular fluids.
From Malarkey and Mc Morrow, 2000.potassium bitartrate a compound administered rectally as a suppository with sodium bicarbonate to produce carbon dioxide, which promotes defecation by distending the rectal ampulla; administered for relief of constipation, and evacuation of the colon before surgical or diagnostic procedures or childbirth.
Maintains acid-base balance, isotonicity, and electrophysiologic balance throughout body tissues; crucial to nerve impulse transmission and contraction of cardiac, skeletal, and smooth muscle.
Signs of potassium deficiency can include weakness and lethargy, rapid pulse, nausea, diarrhea, and tingling sensations.
If the body absorbs enough potassium but the element is not distributed properly, various disorders may develop.Thus an abnormally low content of potassium in the blood may result in an intermittent temporary paralysis of the muscles, known as familial periodic .Potassium deficiency can be treated by administration of potassium supplements. Some are liquids, some are powders to be dissolved in liquids, and some are slow-release tablets that dissolve in the intestine. For many persons on diuretic therapy for hypertension, potassium deficiency can be avoided by increasing their consumption of potassium-containing foods, such as bananas, dates, prunes, and raisins, and potassium supplements are not needed.Also essential for normal renal function and carbohydrate metabolism.• Hypersensitivity to tartrazine or alcohol (with some products)• Acute dehydration• Heat cramps• Hyperkalemia• Hyperkalemic familial periodic paralysis• Severe renal impairment• Severe hemolytic reaction• Severe tissue trauma• Untreated Addison's disease• Concurrent use of potassium-sparing diuretics, angiotensin-converting enzyme (ACE) inhibitors, or salt substitutes containing potassium• Ensure that patient is adequately hydrated and urinating before starting therapy.• Give with meals and a full glass of water or juice to minimize GI upset.• Be aware that potassium preparations aren't interchangeable.• Know that dosages are expressed in m Eq of potassium and that potassium bicarbonate contains 10 m Eq potassium/g.CNS: confusion, unusual fatigue, restlessness, asthenia, flaccid paralysis, paresthesia CV: ECG changes, hypotension, heart block, arrhythmias, cardiac arrest GI: nausea, vomiting, diarrhea, abdominal discomfort, flatulence Metabolic: hyperkalemia Musculoskeletal: weakness and heaviness of legs Drug-drug.ACE inhibitors, potassium-sparing diuretics, other potassium-containing preparations: increased risk of hyperkalemia Drug-diagnostic tests. Salt substitutes containing potassium: increased risk of hyperkalemia Drug-herbs.
