Full TranscriptHi, I'm Cathy, with Level Up RN. In this video, I am going to talk about fluid-volume deficit and fluid-volume access. Very important topics. You can see there's a lot of bold red text on these cards. So if you have our medical-surgical nursing flashcards, definitely pay attention to that bold red text and review those items. So at the end of the video, I'm going to provide you guys a little quiz to test your knowledge of some of the key facts I'll be covering in this video. So definitely stay tuned for that. And if you have our cards, be sure to pull those out so you can follow along with me. With fluid-volume deficit, our fluid output exceeds our fluid intake, which causes hypovolemia. Risk factors associated with fluid-volume deficit include GI losses such as excess vomiting, diuretics, hemorrhaging, diabetes insipidus, as well as hyperventilation. Those are just some of the risk factors. In terms of signs and symptoms, when we have a lack of fluid volume, that's going to cause our blood pressure to drop. So we're going to have hypotension. And then your body will try to compensate for this hypotension by increasing your respiration rate and your heart rate. So you're going to have tachypnea and tachycardia. We're also going to see weak, thready pulses when a patient has fluid-volume deficit. They may feel weak and thirsty. In addition, we will see prolonged capillary refill time. We'll see oliguria. So that means not a lot of urine, which makes sense. If the patient is dehydrated or lacking in fluid volume, they're not going to be peeing a lot. And then, we're also going to see flattened jugular veins. So in terms of labs, we're going to have concentrated blood and concentrated urine. So we're going to see an increase in hematocrit as well as serum osmolarity and BUN. And then, our urine is going to be concentrated as well. So we're going to see an increase in urine specific gravity as well as urine as uring osmolarity. In terms of treatment, we're going to provide the patient with IV fluid replacement. And then for nursing care, we're going to closely monitor the patient's I's and O's because if their urine output drops below 30 milliliters an hour, then that may be indicative of hypovolemic shock. So we're definitely going to want to notify the provider if that urine output falls below 30. And then, we're also going to want to implement fall precautions because the patient's going to be weak and more likely to fall. With fluid-volume excess, we have hypervolemia. So we have excessive intake of fluid or inadequate excretion of fluid. Risk factors include kidney dysfunction. So the kidneys are supposed to get rid of excess fluid and electrolytes. So if the kidneys aren't working properly, then that fluid can back up into the body. Heart failure is another key risk factor for fluid-volume excess because if the heart's not beating effectively, then fluid can back up. Other risk factors include corticosteroids as well as cirrhosis. In terms of signs and symptoms, signs and symptoms of fluid-volume excess can include weight gain, edema, hypertension, bounding pulses, as well as jugular vein distension. It can also cause tachycardia because the heart is being overwhelmed with all this excess fluid. So it will try to beat faster to compensate. The fluid can also back up into the lungs, and that can cause dyspnea as well as crackles and tachypnea. So in terms of labs, when we were talking about fluid-volume deficit, everything was concentrated. The blood and the urine were both concentrated. Here, with fluid-volume excess, everything is diluted. So we're going to have a decrease in hemoglobin and hematocrit in the blood, and we're going to have a decrease in serum osmolarity. The urine is also going to be diluted. So we're going to have a decrease in urine specific gravity. In terms of treatment, the go-to treatment for this is diuretics, and I have a whole video on diuretics in my pharmacology playlist. So you can check that out. In terms of nursing care, we're going to want to weigh our patient on a daily basis. So not once a week, not every other day, every single day. And if the patient has a weight gain of one to two pounds within a 24-hour period or a weight gain of three pounds or more within a week, then we want to notify the provider. We also want to sit the patient up, and we may need to provide oxygen as well to make it easier to breathe. We're going to want to take great care for the patient's skin because their skin will be very fragile if they have a lot of excess fluid. It can be almost like tissue paper if the edema is really bad. We also are likely going to be restricting the patient fluid and sodium intake per orders. And that's going to be really hard on the patient, and sometimes they'll try to hit up anybody who walks in the room to get more fluids. So as the bedside nurse, definitely write it on the whiteboard if the patient is on fluid restrictions, and definitely share that information with the care team as well. As a wound care nurse, sometimes I'm taking care of a patient and as I'm leaving, I'm like, "Do you need anything before I go?" And they're like, "Can you get me some water?" And then I'll look at the whiteboard and I'll say fluid restriction, and I'll be like, "You know what? I'm going to have to check with the nurse," and they're like, "Oh. Almost got it." Anyway, we also want to monitor for complications, which include pulmonary edema, because of that backup of fluid on the lungs, as well as heart failure. So heart failure can cause fluid-volume excess. It can also be a complication of fluid-volume excess. All right. Time for a quiz. Are you guys ready? I have three questions for you. Question number one. When caring for a patient with fluid-volume excess, what amount of weight gain should you report to the provider? The answer is one to two pounds in 24 hours, or three pounds in a week. Question number two. An increase in serum osmolarity and urine specific gravity is expected with fluid-volume excess. True or false? The answer is false. So we would expect this increase with fluid-volume deficit. Question number three. When caring for a patient with a fluid-volume deficit, a urine output less than 30 milliliters per hour may indicate hypovolemic shock. True or false? The answer is true. Okay. I hope that quiz was helpful, and I hope this video has been helpful as well. If so, be sure to like the video and leave me a comment. Take care and good luck with studying.
Fluid Volume Deficit NCLEX Review and Nursing Care Plans Deficient fluid volume, also referred to as Fluid Volume Deficit (FVD), hypovolemia, and even dehydration, is a state in which the fluid volume homeostasis is disturbed due to various factors such as blood loss or body fluid and electrolyte loss. Its incidence is hard to quantify due to non-specific symptoms such as weakness, fatigue, dizziness, muscle cramps, and thirst. Severe hypovolemia may lead to complications such as hypovolemic shock, ischemic stroke, and liver failure. Causes of Deficient Fluid VolumeCommon causes of deficient fluid volume may be classified into renal and extrarenal causes. Renal causes include diuretic excess, mineralocorticoid deficiency, ketonuria, osmotic diuresis, cerebral salt wasting syndrome, and salt-wasting nephropathies; and extrarenal causes which include vomiting, diarrhea, third spacing of fluid, burns, pancreatitis, trauma, and bleeding. Risk Factors to Deficient Fluid VolumeRisk factors to deficient fluid volume are diseases that lead to disturbance of fluid volume homeostasis, which include vomiting, diarrhea, kidney diseases, or decreased blood clotting ability. Note that these are just risk factors and not all people who exhibit these will develop hypovolemia. Signs and Symptoms of Deficient Fluid VolumeManaging deficiency in fluid volume is an important part of patient care especially those patients who are inpatient, in which specific management must be adjusted according to patient needs. No universal protocol exists that fits all patients and thus, to properly care for and manage the fluids of a specific patient, it is important to determine if this patient is fluid deficient or overloaded. The distinction between such conditions may be done through examination of the patient’s vital signs, physical examination findings, and laboratory findings. The following lists the typical findings in hypovolemia:
Fluid Volume Deficit Nursing DiagnosisFluid Volume Deficit Nursing Care Plan 1Cholera Nursing Diagnosis: Deficient Fluid Volume related to acute diarrhea secondary to cholera as evidenced by rapid heart rate, loss of skin elasticity, dry mucous membranes, and low blood pressure, “rice-water stools”, vomiting, thirst, leg cramps, and restlessness/ irritability. Desired Outcome: The goal of nursing care for cholera is to reverse the deficiency in fluid volume, regain the balance in the patient’s nutrition, eliminate infection, repair skin function, and ease the patient’s anxiety.
Fluid Volume Deficit Nursing Care Plan 2Typhoid Fever Nursing Diagnosis: Deficient Fluid Volume related to acute diarrhea secondary to typhoid fever as evidenced by sunken eyes, dry skin and mucous membranes, and lethargy, rose spots, fever, gastrointestinal symptoms, abdominal distension, and pea soup stool. Desired Outcome: The goal of nursing care for typhoid fever includes returning the homeostasis of fluid in the patient’s body, improving patient’s nutritional status, relieving pain, and helping the patient return to his or her normal way of life or activities of daily living (ADL), as well as maintaining the body temperature within normal range.
Fluid Volume Deficit Nursing Care Plan 3Diabetes mellitus Nursing Diagnosis: Deficient Fluid Volume related to polyuria and osmotic diuresis secondary to diabetes mellitus as evidenced by thirst, headache, dry mucous membranes, dizziness, tiredness, and dark yellow colored urine. In severe cases, dehydration related to DM may present as hypotension, sunken eyes, weak pulse and/or tachycardia, and neurologic symptoms such as confusion and lethargy. Other signs and symptoms relevant to DM include an increase in blood glucose levels. Desired Outcome: The goal of nursing care to lower the risk for developing Deficient Fluid Volume in patients with Diabetes mellitus (DM) is to stabilize the parameters related to hydration.
Fluid Volume Deficit Nursing Care Plan 4Older Adult Nursing Diagnosis: Risk for Deficient Fluid volume related to advanced age Desired Outcome: The goal of nursing care to lower the risk for developing Deficient Fluid Volume in older adult patients include maintenance of the patient’s health parameters such as mental status and vital signs to normal limits, and for the patient to avoid exhibiting signs of dehydration such as drying of mucous membranes and “tenting” of skin.
Fluid Volume Deficit Nursing Care Plan 5Chikungunya Infection Nursing Diagnosis: Deficient Fluid Volume related to fluid loss secondary to Chikungunya infection as evidenced by weakness, thirst, dry skin and mucous membranes, sunken eyeballs, decreased urine output, and concentrated urine, fever and joint pain. Desired Outcome: The goal of nursing care for Chikungunya infection includes returning the body temperature of the patient back to normal, restoring the patient’s body fluid homeostasis, easing out pain, and helping improve skin integrity.
