Signs and symptoms that occur in fluid and electrolyte imbalances are discussed below. A: Aqueous fluid and lymphatic fluid is not a part of the ECF. Gallium nitrate: inhibit bone resorption – used in malignant disease. Cell membranes: The cell membrane separates cells from the outside environment, intracellular fluid from interstitial or intravascular fluid. B: The heart and the intestines are not involved in pH regulation. An adrenal gland sits directly above each bean shaped kidney. Excretion is affected by 3 things: excretion of sodium and calcium, blood volume, and parathyroid hormone.↑ PTH → ↓ Mg Excretion↓ Sodium and Calcium excretion → ↓ Mg Excretion↓ blood volume → ↓ Mg Excretion, paresthesia, insomnia, loss of appetite, mood changes, confusion, fatigue, weakness, hallucinations, sensation of heat, decreased deep tissue reflexes, soft tissue calcification, hypotension, weakness, nausea, vomiting, decreased arterial pressure, bradycardia, lost knee jerk reflex (patellar reflex), diaphoresis, coma, flushing, altered mental function, drowsiness, paralysis, paralysis of respiratory muscles may occur when Mg > 10 mEq/L, Treat underlying cause: if magnesium is high due to medication, d/c the medication (antacids or laxatives that have magnesium: Maalox, Mylanta, Mag Citrate, Milk of Magnesia, Mag-Sulfate)Diuretics and 0.45% normal saline: will help increase magnesium excretion, as long as patient has adequate renal function.IV Ca gluconate: counteract neuromuscular effects of Mg if Hypermagnesemia is severe.Dialysis with a low magnesium dialysate (pt with severe renal impairment). Fluid and electrolyte imbalances could result in complications if not treated promptly. If serum sodium levels get below 120 mMol/L neurological symptoms may be seen. Active transport. To maintain electric equilibrium potassium moves out of the cell in response. Fluid and electrolyte balance is essential to the process of life, and abnormal concentrations can be life threatening. Treat underlying cause: correcting electrolyte imbalance, treat diarrhea or fever.

If intake is high, or tissue catabolism occurs the kidneys will quickly compensate and excrete excess serum potassium via the urine. In volume deficit a weak or thready pulse is seen. ADH is produced in the hypothalamus and stored in the posterior pituitary gland, it is released from the posterior pituitary into the blood to act on the kidneys. The osmolality of IV fluids, plasma, urine are used to help paint a picture of volume status in a patient. 5. Replace sodium, fluid and other electrolytes like potassium and bicarbonate. Heart and intestines. Answer: C. Interstitial and intravascular fluids. Studying Fluid and Electrolytes is ridiculously hard and there’s no denying that. If serum sodium levels get below 120 mMol/L neurological symptoms may be seen. Fluid and electrolyte imbalances Fluid and electrolyte balance is essential for health. Sodium contributes 280 mOsm of the 300 mOsm of the blood. Fluid and electrolyte balance Fluid and electrolyte balance McLafferty , Ella; Johnstone , Carolyn; Hendry , Charles; Farley , Alistair 2014-03-19 00:00:00 FLUID AND ELECTROLYTE balance is crucial in maintaining homeostasis within the body. Assess the patient with a fluid or electrolyte imbalance for falls, especially older adults. Look at albumin levels and pH when assessing for deficiency. She is a registered nurse since 2015 and is currently working in a regional tertiary hospital and is finishing her Master's in Nursing this June. 8. Rapid short term weight changes are a sign of fluid status. ECG: monitor for ST- segment depression, presence of accentuated U wave, flattened T wave, ventricular dysrhythmias. Treat underlying cause: correct volume depletion, treat secondary hyperparathyroidism in chronic renal failure: in chronic renal failure excess PTH can lead to elevated phosphorus and bone disease. Fluid balance To attain the correct balance of ECF and ICF a patient must also take in the correct amount of fluid (Docherty and McIntyre, 2002). B: 1,000-2,000 ml is inadequate fluid intake. When blood pressure is decreased it can indicate decrease in fluid volume or possible dysrhythmia from electrolyte abnormalities. If you increase sodium you increase concentration. Skin: exercise, fever, burns, or cystic fibrosis. Fruits such as bananas and apricots 1. Urine osmolality: increased, increased concentration, Urine specific gravity: increased, more concentrated urine as the body tries to conserve fluid, Serum electrolytes: – Potassium: low in GI or renal loss; high in adrenal insufficiency – Sodium: low due to thirst and increased water intake, high with sweat loss, Isotonic Normal Saline: increases intravascular fluid, without increasing intracellular fluid, Saline/Electrolyte solutions: provides fluid and electrolytes (K+, Ca+, Lactate, acetate), hypotonic fluid is used for maintenance fluids, isotonic fluid will replace fluid loss (most fluids lost are isotonic). This study guide helped in addition to my textbook! A clinical manifestation not found in hypokalemia is: A. A: The nurse must assess for nausea and malaise because these are clinical manifestations of hyponatremia. There are different fluid volume disturbances that may affect an individual. Treat underlying cause: partial parathyroidectomy for hyperparathyroidism, chemotherapy for malignant disease, or discontinue ca supplements, vitamin A, vitamin D, thiazide diuretics in renal patients.IV NS solution: Administer rapidly to increased Ca excretion via urine. Fluid volume can also affect temperature: hypovolemia can lead to decreased temperature and vice versa. The body is made of trillions of cells. It is an inverse relationship, as pH goes down potassium goes up and vise versa.Increase total body potassiumTissue breakdown: since the cell is where most potassium is stored, when cells are broken down that potassium is released into the system.Increased Intake: excess potassium rich foods, salt substitutes, transfusions of whole blood or packed red blood cells.Sources of K+ – fruits, vegetables, beans, dairy, meatDecreased K+ excretion from the kidneys due to K+ sparing diuretics, renal failure, or Addison’s diseaseExcretionPotassium is excreted via the kidneys-80%, gastrointestinal tract-15%, and the skin-5%.The kidneys play a big role in potassium regulation. Reestablishment and maintenance of normal pattern and GI functioning. 8. C. A salt. B: CSF is not a part of ECF while interstitial fluid is. In severe depletion, rapid increase in intravascular fluid is priority.Treatment with IV FluidsCrystalloid, Look for medical history that might be associated with fluid or electrolyte disturbances. Serum Sodium: decreased in the presence of water retention. Dehydration test: hold water for 16-18 hrs, administer ADH, wait 1 hour then check serum and urine osmolality. 6. Without proper electrolyte balance the body is unable to carry out the most basic functions. Concentrations.Electrolyte concentrations vary from those in the ICF to those in the ECF. Potassium.The ECF has a low concentration of potassium and can tolerate only small changes in its concentrations. In these cases you may also see increase potassium excretion. Any items you have not completed will be marked incorrect. Embedded in the membranes are different proteins. D: An acid is one type of compound that contains the hydrogen ion. The hypothalamus has osmoreceptors that monitor osmolarity of the blood. Homeostasis is the dynamic process in which the body maintains balance by constantly adjusting to internal and external stimuli. 2. Nurses may use effective teaching and communication skills to help prevent and treat various fluid and electrolyte disturbances. 2. Fluids and electrolytes play a vital role in homeostasis within the body by regulating various bodily functions including cardiac, neuro, oxygen delivery and acid-base balance and much more. Magnesium activates enzymes that breakdown carbohydrate and protein, triggers the Na/K pump, and plays a role is neuron communication and heart function. C. 2,000-3,000 ml. This tool aims to assess the competency level of criticalcare nurses for maintaining fluidand electrolyte balance. Kayexalate: Kayexalate is a resin that binds to potassium in the colon so that it is excreted. Intracellular fluid: The fluid components within the cell are the cytoplasm and neoplasm. C: A salt is a combination of a base and an acid and is created when the positive ions of a base replace the positive hydrogen ions of an acid. Nursing intervention for a patient with a diagnosis of hyponatremia includes all of the following except: Assessing for symptoms of nausea and malaise. Transtubular K+ concentration gradient (TTKG): calculated using potassium and osmolaltiy values in the serum and urine to determine cause of increased potassium levels. If you are practicing to become a nurse, you need to have some information regarding fluids and electrolytes in the human body and how the food and fluids we take up come into play. If this activity does not load, try refreshing your browser. Potassium Replacement via oral or IV medication: 40-80 mMol/day IV divided doses. Since some Calcium in the blood is bound to protein (albumin), when albumin is low total calcium may be low. Different areas of the body are separated by different types of membranes: Client’s responses to treatment, teaching, and actions performed. Please visit using a browser with javascript enabled. Maintenance of fluid volume at a functional level. Risk for digitalis toxicity. Small amounts are also found within the cell.Sodium concentration is important in maintaining the cell membrane potential. When stimulated, BNP works to increase sodium and water excretion by the urine. B: Constipation is not a manifestation of hypocalcemia or hypomagnesemia. In hypervolemia the body compensates with the release of natriuretic peptides- which increase excretion of sodium and water by the kidneys- and inhibition of aldosterone. D: Nuts and legumes are rich in protein. Water is found around cells, inside cells, within vessels, and around organs. Essentially the outside of the cell is more positive and the inside more negative. The amount of body water loss is easily computed by weighing the patient and noting loss of weight: 1 L body water is equivalent to 1 kg, or 2.2 lb, of body weight. D. Restricting tap water intake. Mg def: potassium shifts out of cell, and increased K+ excretion occurs. Advice About The World of Nursing. Later on, muscle weakness is becoming evident, and abdominal distention are noted. Interstitial Fluid: Interstitials fluid is found in many compartments throughout the body. Movement from ECF to ICFIf serum sodium increases some sodium will shift into the cell, maintaining the balance of sodium in the blood.Increase total body sodiumTypical daily intake is usually much higher than our needs.ExcretionExcretion is regulated by several important hormones: aldosterone, angiotensin II, and natriuretic peptides.Changes in serum sodium often reflect changes in fluid status. Diuretics: loop diuretics, thiazide diuretics should not be used, Serum osmolality: is typically decreased (except is hyperglycemia, azotemia), Urine specific gravity: decreased as kidneys excrete excess fluid, Urine sodium: decreased (except in SIADH and adrenal insufficiency). They sit toward the back of the abdomen. Intake: PO fluids (all drinks and foods that are liquid at room temperature), IV Fluids (exact amounts given should be recorded), irrigation (any irrigation that is not pulled back out should be documented), tube feedings (all administered tube feeds and any water flushes). Hyponatremia can lead to increased intracranial pressure and cerebral edema. C: HydroDIURIL is not the diuretic that blocks sodium reabsorption in the distal tubule. Fluid and Electrolyte Balance, Student Notes(4) - Fundamentals of Nursing: the Art and Science of Nursing Care midterm exam study guide with notes from the book and lecture . They are in your blood, urine, tissues, and other body fluids. Dextrose solutions: provides free water which is distributed to intracellular fluid and extracellular fluid, replete total body water deficit. Lastly increased urine production can also cause increase losses of potassiumMg def: potassium shifts out of cell, and increased K+ excretion occurs. In this section we will discuss different types of movement that occur across body membranes. C. Monitoring neurologic status Urine osmolality: increased as kidneys reabsorb water. D. Vascular fluid and CSF. Main Article: 10 Fluid And Electrolyte Imbalances Nursing Care Plans. It can cause loss of cerebral fluid due to increase in serum osmolality. A: Active transport mechanisms require specific enzymes and energy expenditure in the form of adenosine triphosphate (ATP). Mechanism for fluid and electrolyte movementosmosis filtration diffusion # 3. osmosis # 4. diffusion # 5. The most characteristic manifestation of hypocalcemia and hypomagnesemia is: D: Decreased levels of calcium and magnesium leads to tetany. arrhythmias, numbness, tingling fingers, hyperactive reflexes, muscle cramps, tetany, convulsions, tetany, stridor and spasms, lethargy, anxiety, depression, psychosis, decreased heart contractility and heart failure, positive chvostek’s sign and trousseau’s sign. It is the main contributor to osmolality of the blood. Focus topic: Fluids and electrolytes. C: Lack of coordination is not a manifestation of hypocalcemia or hypomagnesemia. Beta2 agonists: this will help shift potassium into the cell. B: The nurse should encourage intake of high-sodium liquids to correct hyponatremia. Fluids found in each compartment are regulated by membranes, concentrations, and hydrostatic pressure. C. Milk and yogurt Although fluid and electrolyte balance and acid/base balance are separate entities, they directly relate to … B. CSF and interstitial fluid. B: Green leafy vegetables are rich in iron. D: 4,000-6,000 ml is inadequate fluid intake. The sodium-potassium pump is an example of active transport. Used with neoplastic disorders. Extracellular fluid: Fluid outside of the cell. To supplement a diet with foods rich in potassium, the nurse should recommend the addition of: A: Bananas and apricots are rich in potassium. Urine potassium: increased is indicative of renal cause, if decreased cause is not renal. Intravascular Fluid: This includes all the blood within the circulatory system: veins and arteries. Nurses need an understanding of the pathophysiology of fluid and electrolyte balance to anticipate, identify, and respond to possible imbalances. Facilitated diffusion: Large molecules or molecules that aren’t lipid soluble require facilitated diffusion. Typically we only absorb 20-30% of dietary calcium. Fluid and electrolytes nursing quiz. Each fluid in the body has unique characteristics that allow for the specific functions within each space. A concentration gradient is simply variations in concentrations in a fluid. Active transport: Active transport is required to move molecules against a concentration or chemical gradient. Phosphorus is the main anion in inside the cell. The NCLEX exam will test your knowledge on how to take care of patients with fluid and electrolyte problems. Balance the amount of water in your body B: Diffusion, or the process of “being widely spread”, is the random movement of molecules from an area of higher concentration to an area of lower concentration.
