Chapter 10 Fluid and Electrolytes Fluid and Electrolyte Balance Necessary for life, homeostasis (internal equilibrium) Nursing role: anticipate, identify, and respond to possible imbalances Copyright © 2022 Wolters Kluwer · All Rights Reserved Fluid Approximately 60% of typical adult is fluid (water and electrolytes) o Varies with age, body fat, gender Intracellular fluid (fluid in cells) Loading… o 2/3 of body fluid, skeletal muscle mass Extracellular fluid (fluid outside the cells) o Intravascular (fluid within blood vessels): plasma, erythrocytes, leukocytes, thrombocytes o Interstitial (fluid that surrounds the cell): lymph o Transcellular: cerebrospinal, pericardial, synovial Copyright © 2022 Wolters Kluwer · All Rights Reserved Electrolytes Active chemicals that carry positive (cations) and negative (anions) electrical charges o Major cations: sodium, potassium, calcium, magnesium, hydrogen ions o Major anions: chloride, bicarbonate, phosphate, sulfate, negatively charged protein ions o Expressed in terms of millequivalents (mEq) per liter Electrolyte concentrations differ in ICF and ECF compartments Copyright © 2022 Wolters Kluwer · All Rights Reserved Regulation of Fluid #1 Osmosis—the diffusion of water caused by fluid and solute concentration gradients Movement of fluid through capillary walls depends on Loading… o Hydrostatic pressure: exerted on walls of blood vessels o Osmotic pressure: exerted by protein in plasma Direction of fluid movement depends on differences of hydrostatic pressure and osmotic pressure Copyright © 2022 Wolters Kluwer · All Rights Reserved Regulation of Fluid #2 Osmosis: area of low solute concentration to area of high solute concentration Diffusion: solutes move from area of higher concentration to one of lower concentration Filtration: movement of water, solutes occurs from area of high hydrostatic pressure to area of low hydrostatic pressure Active transport: Sodium–potassium pump o Maintains higher concentration of extracellular sodium, intracellular potassium Copyright © 2022 Wolters Kluwer · All Rights Reserved Question #1 Is the following statement true or false? Diffusion is the process by which solutes move from an area of higher concentration to one of lower concentration and requires energy. Copyright © 2022 Wolters Kluwer · All Rights Reserved Answer to Question #1 False Rationale: Although diffusion occurs when fluid moves from an area of higher to lower concentration, this process does not require an expenditure of energy. Copyright © 2022 Wolters Kluwer · All Rights Reserved Gains and Losses of Fluid and Electrolytes Gain o Healthy people gain fluids by drinking and eating o Daily I&O of water are equal Loss o Kidney: urine output of 1mL/kg/hr o Skin loss: sensible due to sweating and insensible due to fever, exercise, and burns o Lungs: 300 mL everyday, greater with increased respirations o GI tract: large losses due to diarrhea and fistulas Copyright © 2022 Wolters Kluwer · All Rights Reserved Homeostatic Mechanisms Maintain body fluid within normal limits (Refer to Figures 10-5 and 10-6) o Kidney o Renin– o Heart and Blood Angiotensin– Vessels Aldosterone System o Lung o Antidiuretic o Pituitary Hormone o Adrenal o Osmoreceptors o Parathyroid o Natriuretic o Baroreceptors Peptides Copyright © 2022 Wolters Kluwer · All Rights Reserved Gerontologic Considerations Clinical manifestations of imbalance may be subtle Fluid deficit may cause delirium Decreased cardiac reserve Reduced renal function Loading… Dehydration is common Age-related thinning of the skin and loss of strength and elasticity Copyright © 2022 Wolters Kluwer · All Rights Reserved Fluid Volume Disturbances Fluid volume deficit (FVD): hypovolemia Fluid volume excess (FVE): hypervolemia Copyright © 2022 Wolters Kluwer · All Rights Reserved Fluid Volume Deficit (Hypovolemia) May occur alone or in combination with other imbalances Loss of extracellular fluid exceeds intake ratio of water o Electrolytes lost in same proportion as they exist in normal body fluids Dehydration o Not the same as FVD o Loss of water alone, with increased serum sodium levels Copyright © 2022 Wolters Kluwer · All Rights Reserved Causes of FVD Abnormal fluid losses o Vomiting, diarrhea, sweating, GI suctioning Decreased intake o Nausea, lack of access to fluids Third-space fluid shifts o Due to burns, ascites Additional causes o Diabetes insipidus, adrenal insufficiency, hemorrhage Copyright © 2022 Wolters Kluwer · All Rights Reserved Clinical Manifestations, Assessment and Diagnostic Findings of FVD Can develop rapidly Severity depends on degree of loss See Table 10-4 for clinical signs and symptoms and laboratory findings Copyright © 2022 Wolters Kluwer · All Rights Reserved Gerontologic Considerations for FVD Assessment o Cognition o Ambulation o ADLs o Gag Reflex Copyright © 2022 Wolters Kluwer · All Rights Reserved Medical Management of FVD Oral route is preferred IV for acute or severe losses Types of Solutions o Isotonic o Hypotonic o Hypertonic o Colloid o Refer to Table 10-5 Copyright © 2022 Wolters Kluwer · All Rights Reserved Question #2 Is the following statement true or false? An isotonic solution, such as 0.9% NaCl (Normal Saline), is the only intravenous solution that may be administered with blood products. Copyright © 2022 Wolters Kluwer · All Rights Reserved Chapter 14 Preoperative Nursing Management Perioperative Nursing Preoperative phase: begins when the decision to proceed with surgical intervention is made and ends with the transfer of the patient onto the operating room (OR) bed Intraoperative phase: begins when the patient is transferred onto the OR bed and ends with admission to the PACU (postanesthesia care unit) Postoperative phase: begins with the admission of the patient to the PACU and ends with a follow-up evaluation in the clinical setting or home Copyright © 2022 Wolters Kluwer · All Rights Reserved Surgical Classification Facilitating a diagnosis, a cure, or repair Reconstructive, cosmetic, or palliative Rehabilitative Based upon the degree of urgency involved: Loading… emergent, urgent, required, elective, and optional Copyright © 2022 Wolters Kluwer · All Rights Reserved Preadmission Testing Initiates the nursing assessment process Admission data: demographics, health history, other information pertinent to the surgical procedure Verifies completion of preoperative diagnostic testing according to patient’s needs Begins discharge planning by assessing patient’s need for postoperative transportation and care Copyright © 2022 Wolters Kluwer · All Rights Reserved Preoperative Assessment #1 Health history and physical exam Medications and allergies Nutritional, fluid status Dentition Loading… Drug or alcohol use Respiratory and cardiovascular status Hepatic, renal function Copyright © 2022 Wolters Kluwer · All Rights Reserved Preoperative Assessment #2 Endocrine function Immune function Previous medication use Psychosocial factors Spiritual, cultural beliefs Copyright © 2022 Wolters Kluwer · All Rights Reserved Medications That Potentially Affect Surgical Experience Corticosteroids Anticoagulants Diuretics Anticonvulsant medications Phenothiazines Thyroid hormone Tranquilizers Opioids Insulin Over-the-counter and Antibiotics herbals Copyright © 2022 Wolters Kluwer · All Rights Reserved Question #1 Which medication classification must be assessed during the preoperative period because it can cause an electrolyte imbalance during surgery? A. Corticosteroids B. Diuretics C. Phenothiazines D. Insulin Copyright © 2022 Wolters Kluwer · All Rights Reserved Answer to Question #1 B. Diuretics Rationale: Diuretics during anesthesia may cause excessive respiratory depression resulting from an associated electrolyte imbalance. Corticosteroids can cause cardiovascular collapse if discontinued suddenly. Phenothiazines may increase the hypotensive action of anesthetics. Interaction between anesthetics and insulin must be considered when a patient with diabetes mellitus undergoes surgery. Copyright © 2022 Wolters Kluwer · All Rights Reserved Gerontologic Considerations Cardiac reserves are lower Renal and hepatic functions are depressed Gastrointestinal activity is likely to be reduced Respiratory compromise Decreased subcutaneous fat; more susceptible to temperature changes May need more time and multiple education formats to understand and retain what is communicated Copyright © 2022 Wolters Kluwer · All Rights Reserved Special Considerations During Preoperative Period Patients with obesity Patients with disabilities Patients undergoing ambulatory surgery Patients undergoing emergency surgery Loading… Copyright © 2022 Wolters Kluwer · All Rights Reserved Informed Consent Should be in writing before nonemergent surgery Legal mandate Surgeon must explain the procedure, benefits, risks, complications, etc. Nurse clarifies information and witnesses signature Consent is valid ONLY when signed before administering psychoactive premedication Consent accompanies patient to OR Copyright © 2022 Wolters Kluwer · All Rights Reserved Question #2 Is the following statement true or false? Voluntary and written informed consent from the patient is necessary before nonemergent surgery can be performed solely to protect the surgeon from claims of an unauthorized operation or battery. Copyright © 2022 Wolters Kluwer · All Rights Reserved Answer to Question #2 False Rationale: Voluntary and written informed consent from the patient is necessary before nonemergent surgery can be performed to protect the patient from unsanctioned surgery and protect the surgeon from claims of an unauthorized operation or battery. Consent is a legal mandate, but it also helps the patient to prepare psychologically, because it helps to ensure that the patient understands the surgery to be performed.

Which of the following actions should the nurse take first? A. Have the family present B. Ensure that the preoperative shave is completed C. Have the patient void D. Make sure the patient is covered with a warm blanket Copyright © 2022 Wolters Kluwer · All Rights Reserved Answer to Question #3 C. Have the patient void Rationale: Having the patient void prior to administering a premedication is necessary for patient safety to prevent falls and injury. Shaving is no longer recommended; clipping the hair is evidence-based practice. The family can be present, and a warm blanket can be provided any time patient appears cold or asks for it, but the patient fall risk is greatly increased after receiving preoperative medications that are sedative or amnesic. Copyright © 2022 Wolters Kluwer · All Rights Reserved Expected Outcomes Relief of anxiety Decreased fear Understanding of the surgical intervention No evidence of preoperative complications Copyright © 2022 Wolters Kluwer · All Rights Reserved Answer to Question #2 True Rationale: Tonicity is the tension that osmotic pressure of a solution with impermeable solutes exerts on cell size because of water movement across the cell membrane. Normal saline has nearly the same tonicity as plasma.
