the body are closely linked4. The polar nature of water allows electrolytes such as sodium ions to dissolve. The level of sodium within the body affects the amount of water in and around body cells. The body gets sodium from food and drink‚ and loses it in sweat and urine. Sodium plays an important role in water balance and is required to draw water through plasma membrane of body cells. This is because sodium and water move simultaneously‚ maintaining equilibrium of water and electrolytes across

If a patient has health issues that include congestive heart failure or hypertension‚ they may need to be on a low sodium diet. A nurse can help with cultural repatterning by teaching the client how to reduce the salt or sodium in their diet‚ but at the same time maintaining their cultural food preferences. A nurse can provide recipes for jerk with less salt

major electrolytes that are in our body are as follows: sodium (Na+)‚ potassium (K+)‚ chloride (Cl-)‚ calcium (Ca2+)‚ magnesium (Mg2+)‚ bicarbonate (HCO3-)‚ phosphate (PO42-)‚ sulfate (SO42-). Sodium is an abundant metallic element which is an important mineral for all living organisms. It is also widely used industrially to make an assortment of consumer goods. In a pure form‚ sodium is a soft‚ silvery gray‚ highly reactive metal. Pure sodium is usually stored in a nonreactive substance‚ as it oxidizes

What is the approximate concentration of K+ inside a typical cell (intracellular concentration)? You correctly answered: a. 150 mM 2. What is the approximate concentration of K+ outside a cell (extracellular concentration)? You correctly answered: b. 5 mM 3. What is the approximate concentration of Na+ inside

extracellular Na+ did not significantly alter the membrane potential in the resting neuron? Your answer: There are less sodium leak channels than potassium leak channels‚ and more of the potassium channels are open. 4. Discuss the relative permeability of the membrane to Na+ and K+ in a resting neuron. Your answer: Membrane permeability to sodium is very low because there are only a few sodium leak channels. The membrane is more permeable to potassium because of the higher number of potassium leak channels

commonly defined as a serum sodium concentration ≤135 meq/L [2]. An overview of the causes of hyponatremia will be presented here (table 1). Most of the individual disorders are discussed in detail separately‚ as are issues related to diagnosis and treatment [1‚3]. (See "Diagnosis of hyponatremia" and "Overview of the treatment of hyponatremia".) It should also be emphasized that‚ in selected patients‚ multiple factors may contribute to the fall in the plasma sodium concentration. Symptomatic
