Explain the difference between intracellular and extracellular fluid compartments in terms of electrolyte composition. a. Extracellular is intravascular and interstitial spaces and comprises 1/3 of total body water content. It is in between the cells and in the blood vessels. ECF electrolytes are abundant in sodium and chloride. b. ICF is inside the cell and is approximately 2/3 of the total body water content and it is only inside the cells. More common electrolytes here are potassium and magnesium. 2. Fill in the following table Imbalance Causes S/SX - clinical Sources picture Hyponatremia Hypernatremia Hypokalemia Hyperkalemia Hypocalcemia Hypercalcemia Hypomagnesemia Hypermagnesemia 3. A patient presents with confusion, muscle weakness, and a serum sodium of 120 mEq/L. What electrolyte imbalance do they have, and what are the appropriate nursing interventions? a. They are low in sodium. Hyponatremia b. Assess them neurologically. Administer sodium and see if they need fluids along with the electrolyte supplement. Increase salt intake. May require education. 4. A patient with chronic kidney disease presents with a serum potassium of 6.2 mEq/L. What would you expect on their ECG, and how would you manage this imbalance? a. There would be conduction changes on their EKG, there may also be an abnormal rhythm because the potassium is so high. Hyperkalemia b. They may be unable to filter out this extra potassium, so dialysis may be necessary. 5. A patient in the ICU has a serum calcium of 11.5 mg/dL, constipation, and muscle weakness. What electrolyte imbalance is this, and what interventions would you initiate? a. Hypercalcemia b. Give them calcium supplement. Educate them on diet and limiting intake. Hyperparathyroidism- order labs and see if they have that. 6. A postoperative patient has a serum magnesium level of 1.0 mg/dL and is experiencing muscle cramps. What imbalance is present, and what treatment would you anticipate? a. Hypomagnesemia b. Give them supplemental magnesium IV or PO. Fluid Imbalance and I &Os 1. A client is receiving IV fluids. Intake has been recorded as 3000ml over 24 hours and total output has been measured at 1000ml over 24 hours. This client reports shortness of breath and has visible lower extremity edema. i. What condition do you think this patient is experiencing by recognizing cues? i. Fluid excess, CHF ii. What are your priority actions? i. Alert the provider, stop the fluids, give diuretic iii. How would you evaluate the actions taken? i. Patient will have improved respiratory symptoms and edema will be drained ii. Listen to heart and lungs iii. Inspect and palpate edema in lower extremities iv. Output will increase 2. A 70 y/o client with a history of heart failure presents c/o feeling very lightheaded and confused. Vital signs are as follows: BP 98/64, HR 104 with thready pulse, RR 18, O2% = 98%, postural BP 88/52, postural HR 122. i. What condition do you think this patient may be experiencing? i. Orthostatic hypotension, fluid defecit ii. What other subjective and objective cues would you want to learn? i. Assess neuro ii. How much fluid have they had (quantify the amount) iii. Nutrition iv. Medication changes iii. Based on the information you predict, what actions would you hypothesize? i. Encourage fluids ii. Education on nutrition or medication 3. A client has the following intake and output over the previous 24 hours. Intake: Oral fluids 1500ml IV fluids 1000ml Output: Urine 2000ml Wound drainage 300ml a. Is the client in fluid balance? i. Yes, this is typically normal b. What clinical signs would you expect to see? i. Noting abnormal, patient should appear normal. 4. A client is ordered to receive 2500ml of fluids in 24 hours. The client is receiving IV fluids at a rate of 100ml/hr. i. How much additional fluid would the client need to meet their total fluid requirements if they receive no oral intake? i. 100 mL ii. If the client consumed 400ml of oral fluids in the last 24 hours, how would that affect the IV rate? i. It would slow down. Subtract the 400 from the 2500 and you get 2100. Divide that by 24, and you get 87 mL per hour 5. Mrs. Jones drank 8oz of coffee, ½ of her 8 oz cup of water, ¼ of her 16 oz chicken broth and had a bowl of pasta. Calculate the amount of intake in ml for Mrs. Jones. 1oz = 30ml. i. 480 mL Medication Administration Copyright © 2021, Elsevier Inc. All Rights Reserved.

Recall common fluid, electrolyte imbalances. Explain acid and base concentrations in the blood and identify imbalances. Identify risks factors for fluid, electrolyte, and acid-base imbalances. Apply the clinical judgement measurement model to recognize and assess cues, prioritize hypotheses and implement actions related to fluid and electrolyte imbalances, and acid-base imbalances. Evaluate the outcome of any actions related to correcting fluid/electrolyte imbalances and acid-base imbalances. Table of Topics 1) Introduction 2) Fluid Volume Imbalances o Fluid Volume Excess o Fluid Volume Deficit 3) Common Electrolytes in ICF, ECF 4) Electrolyte Imbalances 5) Acid Base Regulation 6) Acid Base Imbalance 11/10/2024 3 Important Definitions to Understand Osmolality Number of particles per kilogram of water. Isotonic Fluid with the same tonicity as blood. Hypotonic Solution that is more dilute than blood. (less particles per given amount). Hypertonic Solution that is more concentrated than blood (more particles per given amount). Active Transport Requires ATP to move electrolytes in and out of cells (ICF/ECF) (Na+ - K+ pump). Diffusion Passive movement of electrolytes to lower concentrated areas. Osmosis Movement of water across cell membranes 11/10/2024 4 Other Important Concepts/Terms Fluid Intake Absorbing fluid into the body. Drinking, eating foods high in water content, IVF, enemas, irrigation of body cavities. Fluid Distribution Movement of fluid through various compartments. Think osmosis Fluid Output Losing fluid from the body. Urine, vomiting, diarrhea, wound drainage, hemorrhage, sweat. Insensible (not visible) loss through the skin and respiratory tract is constant. Fluid Balance Interplay of 1) fluid intake and absorption, 2) fluid distribution, 3) fluid output. 11/10/2024 5 Questions to ponder..... Can drinking too much water be harmful? Picture yourself having run 5 miles on a day that is supper hot and humid. o How do you feel after the run? o What happened to your body during the run? o What are you craving? Picture yourself eating a full bag of your favorite potato chips. o How do you feel after eating the chips? o What are you craving?

Many older patients take numerous medications. Elderly have decreased sensation of thirst and taste. May drink less water and eat more sodium for flavor. Risk for dehydration, hypernatremia, ECV deficit. Dehydration can lead to postural/orthostatic hypotension. Chronic renal or cardiac medical conditions may limit the amount of fluid that can be delivered at a given time. 11/10/2024 31 Replacement of Fluids Hypotonic Isotonic Hypertonic Meaning Less solutes than ICF Same Tonicity as ICF More solutes than ICF Examples 1/4NS, ½ (0.45%)NS D5W, 0.9% NS or NaCl, LR D10W, D5NS, D5 1/2NS, (Lactated Ringers) D5LR Expected Fluid Shift Expands ECV and Expands ECV and mostly Fluid shifts OUT of cells rehydrates cells. does not enter cells. into ECF (Dextrose enters cells) ** Generally, no fluid shifts) Indications Cellular hydration Fluid and electrolyte Hypovolemia, vascular replacement expansion Risks to assess for Decreased BP?

Compensation – balancing pH to return to normal range o Either PaCO2 or HCO3, or both, will be out of range with a normal pH Fully compensated = pH is in normal range o Both PaCO2 and HCO3 will be out of range, but pH will be normal o If pH is closer to acid, look for that. If closer to base, look for that cause Uncompensated – pH is NOT in normal range; body isn't doing anything to correct Partial compensation – pH is not in range, but the lung or kidney is out of range and trying to get pH back.
