Hypokalemia is a low level of potassium (K +) in the blood serum. [1] Mild low potassium does not typically cause symptoms. [3] Symptoms may include feeling tired, leg cramps, weakness, and constipation. [1] Low potassium also increases the risk of an abnormal heart rhythm, which is often too slow and can cause cardiac arrest. [1] [3]
As a result, the muscle cannot contract efficiently (paralysis). The condition is hypokalemic (manifests when potassium is low; not "causing hypokalemia") because a low extracellular potassium ion concentration will cause the muscle to repolarise to the resting potential more quickly, so even if calcium conductance does occur it cannot be ...
Low potassium is caused by increased excretion of potassium, decreased consumption of potassium rich foods, movement of potassium into the cells, or certain endocrine diseases. [3] Excretion is the most common cause of hypokalemia and can be caused by diuretic use, metabolic acidosis , diabetic ketoacidosis , hyperaldosteronism , and renal ...
Bartter syndrome (BS) is a rare inherited disease characterised by a defect in the thick ascending limb of the loop of Henle, which results in low potassium levels (hypokalemia), [2] increased blood pH , and normal to low blood pressure. There are two types of Bartter syndrome: neonatal and classic.
Pathophysiology (or physiopathology) is a branch of study, at the intersection of pathology and physiology, concerning disordered physiological processes that cause ...
Aldosterone binds to aldosterone receptors (mineralocorticoid receptors) increasing sodium reabsorption in an effort to increase blood pressure and improve fluid status in the body. When excessive sodium reabsorption occurs, there is an increasing loss of K + in the urine and can lead to clinically significant decreases, termed hypokalemia ...
Hypertension, hypokalemia, metabolic alkalosis, and low plasma renin activity. [ 1 ] Apparent mineralocorticoid excess is an autosomal recessive [ 2 ] disorder causing hypertension (high blood pressure ), hypernatremia (increased blood sodium concentration) and hypokalemia (decreased blood potassium concentration).
A progress note is the record of nursing actions and observations in the nursing care process. [13] It helps nurses to monitor and control the course of nursing care. Generally, nurses record information with a common format. Nurses are likely to record details about a client's clinical status or achievements during the course of the nursing care.
