a,b,d,e
A 6-month-old infant is admitted with severe dehydration. Effectiveness of therapy is evaluated with which of the following assessment measures? (Select all that apply.) a Daily weights b Mucous membrane assessment for moisture c Abdominal girth d Level of consciousness e Intake and output
a,b,c,d (Rationale: All of the choices represent assessment measures that measure the effectiveness of therapy except abdominal girth, which does not provide information regarding hydration status. Nursing Process:Assessment Client Need:Physiological Integrity Cognitive Level:Evaluating)
A 6-month-old infant is admitted with severe dehydration. Which of the following assessment measures by the nurse would indicate effective therapy? (Select all that apply.) a Level of consciousness b Intake and output c Mucous membrane assessment for moisture d Daily weights e Abdominal girth
b
A client admitted for nausea and vomiting has a urine-specific gravity of 1.061. Upon assessment of the client, the nurse finds that the client is experiencing orthostatic hypotension and has dry skin and flat neck veins. What is the priority nursing diagnosis for this client when planning care? a Ineffective tissue perfusion b Deficient fluid volume c Impaired skin integrity d Impaired gas exchange
a,b,d,e (Rationale The nurse should anticipate that calcium chloride, sodium bicarbonate, insulin, and glucose would be prescribed to treat the client's hyperkalemia. An ACE inhibitor is used to treat hypertension, not hyperkalemia. Add to this: Ace inhibitors can cause retention of potassium!)
A client diagnosed with acute renal failure is experiencing hyperkalemia. Which medication should the nurse anticipate being prescribed to this client? (Select all that apply.) a Sodium bicarbonate b Insulin c Angiotensin-convertingdashenzyme (ACE) d inhibitors d Glucose e Calcium chloride
d
A client experiencing hyperkalemia is scheduled for dialysis. The nurse anticipates an order for what therapy to help drive potassium back into the cells prior to dialysis? a Antidiuretic hormone b Potassium supplements c Blood transfusion d Insulin
d (Rationale: Dialysis can cause disequilibrium syndrome if fluid is withdrawn too quickly. The nurse should assess for headache, nausea, vomiting, change in level of consciousness, and hypertension. Congestive heart failure is fluid overload. The client is more likely to experience hypokalemia. Peripheral edema is a sign of fluid overload.)
A client has just returned from hemodialysis. For which should the nurse assess this client? a Hyperkalemia. b Peripheral edema and headache. c Congestive heart failure. d Signs of disequilibrium syndrome.
b
A client in the Emergency Department is being admitted for fluid volume deficit. When preparing to assess this client, on which body system should the nurse focus to determine the cause of the imbalance? a Cardiovascular b Gastrointestinal c Genitourinary d Musculoskeletal
a (Rationale: Ringer's solution is an isotonic, balanced electrolyte solution that can expand plasma volume and help restore electrolyte balance. Hypertonic solutions such as 10% dextrose and 3% sodium chloride pull interstitial and intracellular fluid into the vascular system, leading to cellular dehydration. A hypotonic solution such as 0.45% sodium chloride may be used to treat cellular dehydration.)
A client is admitted to the emergency department with hypovolemia. Which intravenous solution would the nurse anticipate administering? a Ringer's solution b 10% dextrose in water c 0.45% sodium chloride d 3% sodium chloride
a
A client is admitted with a serum sodium level of 140 mEq/L, hematocrit level of 31%, and generalized edema. Which priority intervention is indicated for this client? a Restrict fluid intake b Increase sodium intake in the diet c Prepare to administer a blood transfusion d Encourage the client to drink ginger ale
c
A client is admitted with end stage renal disease and a potassium level of 7.1. The nurse anticipates which medication prescription from the healthcare provider? a Magnesium 1 gm IV b Lactated ringers, 500 ml IV bolus c Calcium gluconate 1.5 g IV d Potassium, 20 mEq IV
b
A client is being seen in the Emergency Department for vomiting and diarrhea that has lasted 4 days. The client's current weight is 154 pounds. The physician has diagnosed the client with a viral infection. The nurse has been monitoring intravenous fluids and urine output. What hourly urine measurement would indicate to the nurse that efforts to rehydrate this client have been successful? a 20 mL per hour b 40 mL per hour c 30 mL per hour d 25 mL per hour
b (Rationale: Peritoneal dialysis uses the peritoneal membrane as the dialyzing surface. Metabolic wastes and excess electrolytes diffuse into the dialysate in the abdomen, and an osmotic gradient pulls excess fluid from the blood. Hemodialysis is the process in which the blood volume is filtered through an external filter to remove toxins and excess fluid from the blood. The dialysate fluid does not diffuse into the bloodstream. It remains in the peritoneal space. Fluid is not exchanged in peritoneal dialysis. The same fluid that infuses into the abdomen is what is drained several hours later.)
A client receiving peritoneal dialysis asks the nurse how it works. What is the nurse's best response? a "Your blood is filtered through an external filter that will pull excess fluid and toxins out of your blood." b "The fluid that infuses into your abdomen will pull fluid and toxins from the bloodstream, and then the waste products will drain from your abdomen." c "Your body exchanges the fluid in the bloodstream with the clean fluid in the abdomen, and then the fluid with the toxins drains out." d "The fluid that infuses into your abdomen diffuses into the blood and dilutes the toxins."
b,c,e
A client who has experienced a burn injury over 40 percent of the body is at risk for acute tubular necrosis. What will the nurse do to prevent renal failure in this client? (Select all that apply.) a Reduce sodium intake. b Prevent infection. c Maintain blood pressure. d Increase fluids to prevent crystal formation. e Maintain adequate fluid balance.
b ( Feedback Rationale: A positive Chvostek's sign indicates increased neuromuscular excitability, commonly associated with both hypomagnesemia and hypocalcemia, often seen in people who abuse alcohol and who are nutritionally depleted. Additional manifestations of hypomagnesemia include confusion, hallucinations, and possible psychoses. Administration of magnesium sulfate helps restore magnesium balance and neuromuscular function. The symptoms presented are not those of potassium depletion, the need for glucose and insulin, or sodium depletion.)
A client with a history of alcohol abuse presents with confusion, hallucinations, and a positive Chvostek's sign. Which medication(s) should the nurse anticipate administering? a Sodium bicarbonate b Magnesium sulfate c Insulin and glucose d Potassium chloride
c (Rationale The kidneys produce erythropoietin, which stimulates red blood cell production in the bone marrow. Erythropoietin production decreases in renal failure. Low serum calcium levels in chronic renal failure lead to renal osteodystrophy, or bone breakdown. In chronic renal failure, some red blood cells may be found in the urine but not enough to cause anemia. Fluid overload is common in renal failure but it will not change the red blood cell count.)
A client with chronic renal failure asks the nurse why he is anemic. What is the nurse's best response? a "You are retaining more fluid, so your blood is diluted." b Your bone marrow is depressed because of low calcium levels." c "Your kidneys are not producing a hormone that tells your body to make more blood cells." d "Your kidneys are excreting more blood cells."
a (Rationale: The client with renal failure with a potassium level above 6.5 mEq/L is treated with sodium polystyrene sulfonate (Kayexalate SPS suspension). Sodium polystyrene exchanges sodium ions for potassium in the intestines. Furosemide (Lasix) removes sodium and excess fluid. Aluminum hydroxide (Amphojel) is used to control hyperphosphatemia. Propranolol (Inderal) may control hypertension.)
A client with chronic renal failure has a serum potassium of 6.6 mEq/L. The nurse should anticipate an order for: a sodium polystyrene sulfonate (Kayexalate). b aluminum hydroxide (Amphojel). c propranolol (Inderal). d furosemide (Lasix).
c,d
A client with chronic renal failure has been prescribed diuretics. What are some important nursing activities for this client's care? (Select all that apply.) a Check temperature regularly b Check for swallowing problems c Monitor intake and output d Check hydration status e Monitor client for anxiety
d (Rationale: The client needs to be assessed for a functional arteriovenous fistula by palpating a thrill and auscultating a bruit. Clients may have edema, which is usually peripheral. A renal bruit indicates turbulent blood flow in the renal artery. A positive Homan's sign may indicate a deep vein thrombosis.)
A client with chronic renal failure has had an arteriovenous fistula created for hemodialysis. The nurse should assess this client for: a periorbital edema. b a renal bruit. c homan's sign. d a bruit and a thrill.
d (Rationale: Unless a kidney is received from an identical twin, the body will produce antibodies and will begin to reject the kidney. Immunosuppressants suppress the immune system and the inflammatory response. Bone marrow production is part of the suppressed immune system. The risk for infection is greater with this treatment because the immune system is suppressed.)
A client with end-stage renal disease has received a kidney transplant. The client asks, "Why do I need to take cyclosporine (Sandimmune)?" What is the best response by the nurse? a "It will help prevent infection." b It will increase your immune system to prevent rejection." c "It increases bone marrow cell production to assist in preventing rejection." d "It will help prevent rejection of the kidney by suppressing your immune system."
K,Na
A client with renal failure should avoid foods high in ___ and ____.
b (Rationale A renal biopsy is done to differentiate between acute and chronic renal failure, so the nurse should provide education for this diagnostic test. A renal ultrasonogram identifies obstructive causes of renal failure and does not differentiate between acute and chronic renal failure. Therefore, the nurse should not provide education for this diagnostic test. A CT scan or an MRI evaluates kidney size and identifies possible obstructions, but it does not differentiate between acute and chronic renal failure; therefore, the nurse should not provide education for these diagnostic tests.)
A client with renal failure will be undergoing a diagnostic test that will differentiate between acute and chronic renal failure. For which diagnostic test should the nurse provide education? a CT scan b Renal biopsy c Renal ultrasonography d MRI
a (Rationale The client with ESRD will often experience a disturbance in body image. The client should be encouraged to express feelings in an accepting environment. Referral for mental health counseling may be indicated for a client with chronic renal disease. However, the nurse should make open-ended statements to allow the client to express feelings. The client should be supported in an environment without criticism. The nurse should not support denial. The client should be encouraged to participate in self-care.)
A client with end-stage renal disease (ESRD) tells the nurse, "I feel like half a person. How can I go out in public looking like this?" What is the nurse's best response? a "You seem to be upset about the changes that have occurred in your body as a result of your disease." b "Would you like to speak with the hospital chaplain?" c "You do not look all that bad. Would you like me to help you wash your hair?" d "You should be happy that you are alive."
c
A home health nurse is seeing a client with congestive heart failure. The client is taking furosemide (Lasix). The nurse reviews the client's most recent serum potassium, which was 3.4 mEq/L. Which food would the nurse encourage this client to choose from the dinner menu? a Baked fish b Iced tea c Banana d Peas
a,c,d,e (Rationale Sodium polystyrene sulfonate (Kayexalate) is a potassium-ion exchange resin that removes potassium by exchanging sodium ions for potassium in the small bowel. A combination of regular insulin, bicarbonate, and glucose (dextrose) facilitates the movement of potassium ions into the cells to decrease serum potassium levels. A serum potassium level of 6.6 mEq/L is hyperkalemic, so potassium replacement is not appropriate.)
A nurse caring for a client with chronic renal failure notes that the client's potassium level is 6.5 mEq/dL.The nurse anticipates which orders for this client? (Select all that apply.) a Sodium bicarbonate b Potassium 30 mEq in 100 mL IV over 2 hours. c IV regular insulin d Sodium polystyrene sulfonate (Kayexalate) e IV 50% dextrose solution
d
A nurse is assessing a client who is dehydrated for fluid volume deficit. Which of the following findings should the nurse expect from this client? a Moist skin b distended neck veins c increased urinary output d tachycardia
c
A nurse is unable to secure an intravenous access site due to severe dehydration. Which order does the nurse anticipate receiving from the healthcare provider? a Diuretics b Oral fluid replacement c Hypodermoclysis d Sodium supplements
d
A pediatric nurse is assigned phone triage for the shift. The nurse takes a call from the mother of a 3-month-old infant. The mother tells the nurse that the child has been vomiting and experiencing diarrhea for several days. Which nurse response is most appropriate? a "Measure your baby's urine output for 24 hours and call back tomorrow." b "Give your baby 50 mL of glucose water every hour." c "Give your baby at least 2 ounces of juice every 2 hours." d "You should bring the infant in to be seen by the doctor."
Na
Renin-angiotensin-aldosterone system: an enzyme pathway that acts on the blood vessels and nephrons of the kidneys; net effect is restoration of blood volume through _______ and water retention
2500
Adult fluid intake should be _______ mL/day
a
After a client has returned from surgery, the nurse needs to report which urinary output? a 20 mL per hour b 40 mL per hour c 300 mL per 8 hours d 400 mL per 8 hours
a (Rationale: The client's ability to state renal replacement therapies indicates understanding of treatment options and the ability to make informed decisions on treatment. Clients may be able to live independently, or with the assistance of a part-time caregiver. Home hemodialysis would require a helper for safety reasons to monitor the client's response. Hospice care is not needed for ESRD.)
An appropriate goal of nursing care for a client with end-stage renal disease is that the client will be able to: a State the advantages and disadvantages of hemodialysis, peritoneal dialysis, and kidney transplant as renal replacement therapies. b Demonstrate the ability to independently perform hemodialysis in the home. c Identify a live-in caregiver. d Relate the hospice philosophy and identify indicators of the need for hospice care.
d
An elderly client is admitted to the hospital after a fall. The client appears intermittently confused. What is a primary concern of the nurse regarding fluid and electrolytes when caring for this client? a Risk of kidney damage b Risk of stroke c Risk of bleeding d Risk of dehydration
b,c,d
An emergency room nurse is assessing a client who overhydrated during a marathon. Which assessment is essential for the nurse to perform during the physical examination? (Select all that apply.) a Teeth b Level of consciousness c Lung sounds d Blood pressure e Eye accommodation
c
An 86-year-old client is brought to the Emergency Department from a long-term care facility. The client has been experiencing fever, nausea, and vomiting for the past 2 days. The client denies thirst. Urine dipstick indicates a decreased urine specific gravity. The nurse would interpret this finding to be consistent with which of the following? a Congestive heart failure b Normal changes of aging c Dehydration d Fluid overload
d (Fluid intake for clients with renal failure is usually restricted because the kidneys cannot eliminate fluids normally. Fluid intake is calculated for these clients by adding the amount of output for the previous 24 hours to 500 mL to allow for insensible losses. Mr. Sanger's output for the past 24 hours was 250 mL; added to 500 mL, the fluid volume calculation equals 750 mL. A fluid intake of 1,250, 2,750, or 3,000 mL would be too much fluid for Mr. Sanger and put him at risk for fluid overload.)
Benjamin Sanger is a 63-year-old man admitted to the hospital with postrenal failure because of a kidney stone. During the past 24 hours, he has voided 250 mL of urine. He has not had any other type of output. How much fluid should Mr. Sanger receive over the next 24 hours? a 1,250 mL b 3,000 mL c 2,750 mL d 750 mL
9-11
Calcium (Ca2+) ___-___ mg/dL (total)
Diabetes mellitus, Hypertension
Certain disorders are associated with hyponatremia, hypomagnesemia, and hypokalemia, including: ___________ _________, _____________
osmosis
__________________is the movement of water across cell membranes from the side with the less concentrated solution to the side with the more concentrated solution to equalize the concentration in solutions on both sides of the membrane.
K
Excess ______ loss through the kidneys is often caused by such medications as corticosteroids, potassium-wasting (loop) diuretics, (not thiazide) amphotericin B, and large doses of some antibiotics. (electrolyte initial only)
2500
Fluid output for the average healthy adult should equal the ___________ mL/day of input.
d (Rationale: Cloudy urine could be a symptom of an infection. Prompt treatment is vital to preserve integrity of the transplanted organ in an immunosuppressed client. Recording the finding is insufficient; action must be taken. The nurse does not increase the intravenous flow rate without a physician's order. Irrigation of the urinary catheter would introduce possible contaminants into an immunosuppressed client.)
Following a kidney transplant, the nurse notes that the client's urine is cloudy. The most appropriate action by the nurse is to: a Increase the intravenous flow rate. b Record the finding. c Irrigate the urinary catheter. d Notify the physician.
increases decreases
Hct _____________ with severe dehydration and ____________ with severe overhydration. (answer with 2 words, no comma)
high
Hct and Hb values are ________ with dehydration
b
How much urine output is considered normal for a client experiencing acute renal failure? a 25 mL/hr b 30 mL/hr c 15 mL/hr d 20 mL/hr
calcemia
Hyper___________ can occur from immobility. Ambulation of the client helps to prevent leaching of calcium from the bones into the serum.
b (Mr. Hill's rising serum creatinine indicates that he is developing renal dysfunction. The nurse should monitor his urine output and report a rate of less than 30 mL/hr so that early interventions can be implemented to help restore renal function. Renal dysfunction alters the kidney's ability to excrete potassium and can result in hyperkalemia. However, a serum potassium levelof 4.0 mEq/L is within normal limits. Therefore, Mr. Hill should not receive a potassium supplement. Gentamicin is a nephrotoxic drug and should not be administered to Mr. Hill given his compromised renal function. Mr. Hill's indwelling urinary catheter should remain in place so his urine output can be closely monitored.)
James Hill is an 80-year-old man who was admitted to the hospital with gastrointestinal bleeding and hemorrhagic shock. Despite blood product administration and cauterization of his duodenal ulcer, his serum creatinine has risen to 2.2 from 1.1 mg/dL over the past 10 hours. His serum potassium level is 4.0 mEq/L. Which intervention would the nurse include in the care plan for Mr. Hill? a Removing the indwelling urinary catheter b Reporting urine output of less than 30 mL/hr c Administering intravenous gentamicin as prescribed d Administering potassium replacement
a (Rationale: Hypokalemia affects nerve impulse transmission, including the transmission of cardiac impulses. The client may develop ECG changes and atrial or ventricular dysrhythmias. Although hypokalemia can lead to muscle weakness and activity intolerance, bed rest generally is unnecessary. Starting oxygen would be appropriate only if the client is in respiratory distress. The client is more likely to experience cardiac arrest, not seizures; in any case, the priority is cardiac monitoring. The client is not hypoxic, so oxygen is not needed.)
Laboratory results for a client show a serum potassium level of 2.2 mEq/L. Which of the following actions would the nurse do first? a Initiate cardiac monitoring. b Start oxygen at 2 L/min. c Initiate seizure precautions. d Keep the client on bed rest.
b
Laboratory results for a client show a serum potassium level of 2.2 mEq/L. Which of the following nursing actions is of highest priority for this client? a Keep the client on bed rest. b Initiate cardiac monitoring. c Initiate seizure precautions. d Start oxygen at 2 L/min.
1.5-2.5
Magnesium (Mg2+) ____-____ mEq/L
HCO3
Major buffer in acid-base regulation in the body
c (Chronic hypertension, with its resulting sclerosis and reduced blood flow, can result in chronic renal failure because of the long-term effects of hypertension on the blood vessels of the kidney. Elevated lipid levels, social drinking, and obesity are not risk factors for developing chronic renal failure.)
Mr. Cain is a 70-year-old African American male who recently developed chronic renal failure, which was initially identified by elevated serum blood urea nitrogen (BUN) and creatinine levels. Which item in the client's health history may be a factor in the development of chronic renal failure? a Hypertriglycerides b Obesity c Hypertension d Social drinking for 20 years
d (The client is taking glucocorticoids to prevent rejection of the new kidney. Glucocorticoids do not prevent infection, boost immunologic function, or control hypertension.)
Mrs. Taylor is a 42-year-old woman who has been receiving hemodialysis for 8 years. A kidney match became available recently, and Mrs. Taylor underwent a kidney transplant. She began taking an immunosuppressant medication and glucocorticoids postoperatively. When the nurse discusses and administers her medications, which statement by Mrs. Taylor indicates that she understands the action of the glucocorticoids? a "I am taking the glucocorticoid to prevent infection after surgery." b "The glucocorticoid will boost my immune system." c "I am taking the glucocorticoid to help control my elevated blood pressure." d "The glucocorticoid will prevent my body from rejecting the new kidney."
c (An appropriate intervention for a client with disturbed body image is to encourage the expression of feelings related to the disease process and the treatments. While support groups are encouraged, the nurse would not recommend that the client speak to an adolescent client with chronic renal failure. While offering written information regarding treatment is important, this intervention is not appropriate for a client with disturbed body image. Telling the client to increase her physical activity to avoid gaining weight is not therapeutic.)
Ms. Simpson is a 26-year-old woman who was diagnosed with polycystic kidney disease at birth and has developed chronic renal failure. She began receiving peritoneal dialysis a few weeks ago. While the nurse is teaching Ms. Simpson about how to care for her peritoneal catheter, she says, "I look so fat doing this dialysis!" Which nursing action would help Ms. Simpson cope with her disturbed body image? a Recommend that Ms. Simpson increase her physical activity to be sure that she does not gain weight. b Offer Ms. Simpson some written information regarding the technical aspects of her dialysis procedure. c Encourage expression of feelings related to her disease and treatment, and their impact on her life. d Recommend that Ms. Simpson speak with adolescents who also have developed chronic renal failure.

ECF
Primary solutes found in _______ Oxygen Electrolytes: Sodium Chloride Bicarbonate Plasma also contains large amounts of the protein albumin. Interstitial fluid contains little or no protein.
isotonic
Ringer's solution is an (isotonic/hypertonic/hypotonic), balanced electrolyte solution that can expand plasma volume and help restore electrolyte balance
c (Children are at greatest risk for developing acute renal failure from acute gastrointestinal illnesses. Therefore, the nurse needs to further question Rosa's parents about recent acute gastrointestinal illnesses. Major surgery, infections, and certain medications that are nephrotoxic can increase the risk for acute renal failure in older adult clients.)
Rosa Serrano is a 6-year-old child admitted to a medical unit. You notice that Rosa is lethargic and has generalized edema. When reviewing the laboratory results, the nurse finds that Rosa is experiencing gross hematuria. Which further information would the nurse obtain from the parents to assist with the diagnosis of acute renal failure? a Current medications b Past infections c Recent acute gastrointestinal illness d Previous major surgery
Mg
Second most abundant cation in ICF Vital to metabolism and to protein and DNA synthesis in ICF Regulates neuromuscular and cardiac function in ECF
glucose,insulin
Serum K levels may be temporarily lowered by administering ___________and ____________, which cause potassium to leave the extracellular fluid and enter cells.
a,d,e
The nurse is caring for a client who is experiencing diarrhea. Which data indicates that the client is experiencing fluid volume deficit? (Select all that apply.) a Increased heart rate b Weight gain c Increased urine output d Poor skin turgor e Orthostatic hypotension
b
The healthcare provider ordered a diuretic that inhibits sodium and chloride reabsorption in the ascending loop of Henle. The nurse recognizes that this medication is part of what class of diuretics? a Thiazide b Loop c Potassium sparing d Osmotic
d
The neonatal nurse explains to new parents that infants are at greater risk for fluid and electrolyte imbalance than are older children. Which of the following parent comments would indicate that further education is needed? a "An infant has little body water for reserve, as compared with an adult." b "Infants have a higher metabolic rate than older children do." c "Infants lose water through their skin, and they have a larger proportion of skin surface area than older children do." d "Infants maintain their temperature by losing heat through their heads."
b ( Feedback Rationale: Losing heat through their heads will have minimal effect on fluid loss in infants. All the other answers are appropriate responses)
The neonatal nurse explains to new parents that infants are at greater risk for fluid and electrolyte imbalance than are older children. Which of the following parent comments would indicate that further education is needed? a "Infants have a higher metabolic rate than older children do." b "Infants maintain their temperature by losing heat through their heads." c "An infant has little body water for reserve, as compared with an adult." d "Infants lose water through their skin, and they have a larger proportion of skin surface area than older children do."
a,c,d
The nurse caring for a client preparing to undergo hemodialysis will include which in the plan of care? (Select all that apply.) a Obtain weight and orthostatic vital signs. b Determine urine specific gravity and pH. c Assess blood pressure of extremity where fistula has been created. d Monitor serum creatinine, BUN, and hematocrit levels. e Restrict fluid and protein intake.
a,b,d
The nurse caring for a client with acute hypernatremia includes which of the following in the plan of care? (Select all that apply.) a Maintain intravenous access. b Conduct frequent neurologic checks. c Restrict fluids to 1500 mL per day. d Orient to time, place, and person frequently. e Limit length of visits.
d (A diagnostic test used to assess kidney function is serum creatinine levels. Hemoglobin and hematocrit are used to assess hemoconcentration in the blood. Serum osmolality helps to differentiate isotonic fluid loss from water loss.)
Which diagnostic test assesses kidney function? a Serum osmolality b Hemoglobin c Hematocrit d Serum creatinine
a,c,e (Rationale: Frequent neurological checks are necessary as hypernatremia draws water out of brain cells, causing them to shrink. As the brain shrinks, tension is placed on cerebral vessels, which may cause them to tear and bleed. Hypernatremia affects mental status and brain function (including orientation to time, place, and person), as can rapid correction of hypernatremia. Fluid replacement is the primary treatment for hypernatremia. Maintaining intravenous access is necessary for administration of fluids and possible emergency medications. There is no reason to limit visit length.)
The nurse caring for a client with acute hypernatremia would include which of the following in the plan of care? (Select all that apply.) a Conduct frequent neurologic checks. b Restrict fluids to 1500 mL per day. c Orient to time, place, and person frequently. d Limit length of visits. e Maintain intravenous access.
c
The nurse evaluates client teaching as effective when the client recovering from acute renal failure states: a "I will consume only vegetable proteins." b "I will limit my intake to 1500 mL or less per day." c "I will avoid taking drugs that may be nephrotoxic." d "I will self-catheterize for residual urine at least once a week."
c
The nurse has just received a shift report on a pediatric medical-surgical unit. The nurse has been assigned four clients for the shift. The nurse is reviewing the assignment and determines that which child is at greatest risk for dehydration? a A 10-year-old child with cellulitis of the left leg b A 4-year-old child with a broken leg c A 15-month-old child with tachypnea d A 16-year-old child with migraine headaches
a (Rationale Impaired potassium excretion leads to hyperkalemia, which causes electrocardiographic changes. Hypotension, constipation, and weight gain are not manifestations of hyperkalemia.)
The nurse identifies that a client in acute renal failure is experiencing hyperkalemia. For which manifestation should the nurse monitor the client? a Electrocardiographic changes b Constipation c Weight gain d Hypotension
d (Rationale: Respiratory distress due to increased pressure from the dialysate may occur unless the client remains in semi-Fowler's or Fowler's position. Lateral, supine, or dorsal recumbent positions may increase the risk of respiratory distress)
The nurse instructs a client who is on peritoneal dialysis to remain in which of the position? a Dorsal recumbent bSupine c Lateral Sims's d Semi-Fowler's
b
The nurse is administering a blood transfusion to a client who is hemorrhaging. The nurse identifies that the client is experiencing a deficit in which body fluid compartment? a Interstitial fluid b Intravascular fluid c Transcellular fluid d Intracellular fluid
d
The nurse is caring for a client admitted for dehydration. What assessment finding indicates a loss of fluid over a period of time? a Increase in tongue size b Bradycardia c Polyuria d Dry, sticky mucous membranes
b
The nurse is caring for a client admitted with a diagnosis of acute renal failure. The client asks the nurse, "Are my kidneys failing? Will I need a kidney transplant?" What is the appropriate nurse response? a "When the doctor comes to see you, we can talk about whether you will need a transplant." b "Your condition can be reversed with prompt treatment and usually will not destroy the kidney." c "Kidney transplantation is highly likely, and it would be a good idea to start talking to family members." d "No, don't think that. You're going to be fine."
d (Rationale Sepsis causes prerenal acute renal failure because it causes altered vascular resistance. Fluid retention is not a cause of prerenal acute renal failure. Renal calculi are not a cause of prerenal acute renal failure but are the cause of postrenal acute renal failure. Glomerulonephritis is not the cause of prerenal acute renal failure but is the cause of intrarenal acute renal failure.)
The nurse is caring for a client diagnosed with acute renal failure. Which condition most likely caused prerenal acute renal failure in this client? a Glomerulonephritis b Renal calculi c Fluid retention d Sepsis
d (Rationale Urethral obstruction resulting from cancer is the cause of postrenal acute renal failure and is not the cause of prerenal, intrarenal, or intrinsic acute renal failure.)
The nurse is caring for a client in acute renal failure resulting from an obstruction due to cancer. Which type of acute renal failure is the client experiencing? a Intrinsic b Prerenal c Intrarenal d Postrenal
b (Rationale: A client in the maintenance phase of acute renal failure will experience azotemia, which is more severe in a client with oliguria. Muscle weakness, anemia, and dehydration typically are not more severe when experiencing oliguria.)
The nurse is caring for a client in the maintenance phase of acute renal failure. Which manifestation typically is more severe if the client is experiencing oliguria? a Muscle weakness b Azotemia c Anemia d Dehydration
d
The nurse is caring for a client receiving a blood transfusion. Ten minutes after the transfusion of a unit of packed red blood cells was initiated, the client complains of a headache.

d (Rationale The first stage of renal failure, decreased renal reserve, is characterized by a slight decrease in the glomerular filtration rate (GFR), but the client is asymptomatic. A longstanding history of poorly controlled hypertension along with diabetes predisposes the client to the development of renal disease, and the client should be closely monitored. In stage 1 of chronic renal failure, the BUN and creatinine levels are within normal limits. Renal insufficiency is characterized by a further decrease in the GFR, and the BUN and creatinine levels will begin to increase. Renal failure is characterized by azotemia, oliguria, and a sharp increase in the BUN and creatinine levels.)
The nurse is caring for a client with a 20-year history of poorly controlled hypertension and type 2 diabetes mellitus. The morning's laboratory work shows a blood urea nitrogen (BUN) level of 18 mg/dL and a creatinine level of 0.9 mg/dL, and the client had a urine output of 400 mL over the past 8 hours. What is the nurse's correct assumption about this client's renal status? a The client has normal renal function. b The client is experiencing renal insufficiency. c The client is experiencing renal failure. d The client will need to be monitored for advancing renal disease.
c

Which electrolyte imbalance is treated with calcium gluconate? a Hypernatremia b Hyponatremia c Hypochloremia d Hyperkalemia
c (Rationale In diabetic nephropathy, thickening and sclerosis of the glomerular basement membrane and glomerulus lead to gradual nephron destruction and a fall in the glomerular filtration rate (GFR). Polycystic kidney disease results in multiple bilateral cysts compressing renal tissue, impairing renal perfusion and causing ischemia; release of inflammatory mediators damages and destroys normal kidney tissue. In a client with systemic lupus erythematosus, immune complexes in the capillary basement membrane lead to inflammation and sclerosis with focal, local, or diffuse glomerulonephritis. Hypertension affects the glomerulus in that it leads to sclerosis and narrowing of renal arterioles, reducing blood flow and causing ischemia, glomerular destruction, and tubular atrophy.)
The nurse is discussing the pathophysiology of diabetic nephropathy with a nursing student. The nurse asks the student to describe this pathophysiologic process. Which response indicates to the nurse that the student understands diabetic nephropathy? a "Excess pressure in the glomerulus causes the damage in diabetic nephropathy." b "Cysts in the kidney press on the functional tissue." c "The capillary walls in the nephron become thickened." d "Antibody and antigen complexes get stuck in the nephron."

(Select all that apply.) a Observing mental status b Instructing the client to stand slowly c Turning the client every 2 hours d Monitoring for evidence of skin breakdown e Obtaining daily weight
a,c,d,e (Rationale The client will need to continue dietary restrictions, monitoring blood pressure, and monitoring symptoms of possible relapse after discharge, so these statements indicate client understanding of the education. The client will need to avoid life stressors, which can slow healing, after discharge, so this statement indicates client understanding of the education. The client needs to avoid nephrotoxic drugs for up to 1 year after an episode of acute renal failure, so this statement does not indicate understanding of the education.)
The nurse is preparing client education to address the problem of readiness for enhanced knowledge. Which client statement indicates understanding of how to manage acute renal failure after discharge? (Select all that apply.) a "I will monitor my blood pressure." b "I need to avoid nephrotoxic drugs for 1 month." c "I need to continue with dietary restrictions." d "I will avoid life stressors." e "I must monitor for symptoms of possible relapse."
d (Rationale: Carbohydrates are increased for a client with acute renal failure in order to maintain adequate caloric intake. For a client with acute renal failure, protein is limited in the diet to reduce the risk of azotemia. Decreasing dietary fiber and dairy intake is not essential for a client with acute renal failure.)
The nurse is preparing to educate a client diagnosed with acute renal failure about dietary needs. Which information should the nurse include? a Increase protein b Decrease dairy c Decrease fiber d Increase carbohydrates
b,e (Rationale: High levels of urea mixing with sweat can result in uremic frost, crystallized deposits of urea on the skin. The condition will cause pruritus. Bruising is a common manifestation of chronic renal failure, but this manifestation is caused by impaired platelet function. Clients with ESRD may develop a yellowish tinge to the skin because of retained pigmented metabolites, but a yellowed sclera is significant of other disease processes. Dry skin with poor turgor is a common dermatological assessment in clients with ESRD.)

a (Rationale Jehovah's Witness clients typically have strong beliefs regarding blood transfusions. Jehovah's Witness clients are not known to refuse medications prior to surgery. The client may or may not request counsel from their elder (pastor), but will not request counsel from a spiritual leader of another faith.)
The nurse is providing care to a client with chronic renal failure. The nurse reads in the medical record that the client is a Jehovah's Witness. The client is scheduled to receive a kidney transplant in several weeks. Which action does the nurse expect from this client? a To adhere to the beliefs of Jehovah's Witnesses regarding blood transfusions b To sign a consent for donor transfusion during the surgery c To refuse all medications prior to surgery d To request counsel from the hospital chaplain
a (Rationale The cardiovascular assessment finding that supports the diagnosis of chronic renal failure is systemic hypertension. Anemia is a hematologic symptom of chronic renal failure. A decreased white blood cell count is a manifestation of chronic renal failure that affects the immune system. Hyperkalemia occurs as the result of the effects of chronic renal failure on fluids and electrolytes.)
The nurse is providing care to a client with chronic renal failure. Which cardiovascular assessment finding supports this diagnosis? a Systemic hypertension b Anemia c Decreased white blood cell count d Hyperkalemia
d (Rationale The client with chronic renal failure would require a sodium-restricted diet of no more than 2 g/day. Fluid restrictions, daily weighing, and dairy restrictions are appropriate prescriptions for the client with chronic renal failure.)

(Select all that apply.) a Drink water when they feel thirsty b Older adults are at less risk c Take frequent rest breaks d Avoid participating in the tree planting if ill e Wear lightweight clothes
b,c,d,e (Rationale Hypertension, hemolysis, glomerulonephritis, and vasculitis cause acute damage to the renal parenchyma and nephrons, leading to intrarenal acute renal failure. Dehydration causes prerenal acute renal failure and does not cause damage to the renal parenchyma and nephrons.)
The nurse is providing education to a new nurse about renal failure. Which condition causes damage to the renal parenchyma and nephrons? (Select all that apply.) a Dehydration b Vasculitis c Hemolysis d Glomerulonephritis e Hypertension
a
The nurse is reviewing client data to begin planning care. Which client is at greatest risk for developing fluid volume excess? a A client admitted for cirrhosis b A client admitted for overuse of laxatives c A client admitted for oral surgery d A client admitted for nausea and vomiting
c
The nurse is reviewing laboratory values for a client with hyperthyroidism. Which component of the complete blood count will be most useful to the nurse in determining the client's fluid status? a Red blood cell count b Platelet count c Hematocrit d White blood cell count
c,d
The nurse is reviewing the intake and output (I&O) records of a client. Which entry in the intake record would cause the nurse concern? (Select all that apply.) a Tube feedings b Parenteral fluids c Tube drainage d Vomitus e Intravenous medications
a

Which nursing intervention would address this client's phosphorus level? a Encourage consumption of milk and yogurt. b Enforce contact precautions. c Encourage consumption of a high-calorie carbohydrate diet. d Strain all urine.
c
The nurse is reviewing the medication record of a client admitted with dehydration. Which medication would cause the nurse concern? a Nonsteroidal anti-inflammatory drug (NSAID) b Selective serotonin reuptake inhibitor (SSRI) c Benzodiazepine d Vasodilator
d (Rationale: Calcium should be taken with a full glass of water to allow maximum absorption. It is more effectively absorbed when it is taken on an empty stomach and the prescribed doses are spaced throughout the day. Taking calcium is not an immediate fix for problems; it is a long-term replacement therapy.)
The nurse is teaching a client about calcium supplement therapy. Which statement made by the client indicates understanding? a "I will take my calcium tablets with meals." b "I will take my calcium tablets as needed for tremulousness." c "I will take my calcium tablets all at one time in the morning." d "I will take my calcium tablets with a full glass of water."
a,b (Rationale Long-term renal complications of diabetes involve thickening and sclerosis of the glomerular basement membrane and the gradual destruction of the nephron unit. Diabetes and hypertension are the leading cause of end-stage renal disease. It is important to have good control over both blood pressure and blood sugar as a preventive measure against chronic renal failure. Frequent follow-up of laboratory work is important for a client with diabetes and hypertension. Daily monitoring of blood pressure and blood sugar will assist the client in maintaining good control over the disease processes.)
The nurse is teaching a client about the long-term complications of diabetes and hypertension. The nurse knows that additional teaching is required when the client makes which statements? (Select all that apply.) a "My doctor told me the only thing I need to worry about with my high blood pressure is a heart attack or stroke." b "I don't need to worry about my kidneys because diabetes is about sugar in the blood." c It is important that I get my laboratory work drawn like the doctor orders." d "I will try to have good control over my blood pressure." e "I will check my blood sugar and blood pressure every day."
a
The nurse is teaching a group of children and their parents about the importance of exercise. The topic for this specific session is preventing heat-related illnesses for children who exercise. Which statement by a parent indicates understanding of preventive techniques taught? a "I will have my child stop every 15-20 minutes during the activity for fluids." b "Water is the drink of choice to replenish fluids that are lost during exercise." c "It is important for my child to wear dark clothing while exercising in the heat." d "My child only needs to hydrate at the end of an exercise session."
a (Rationale: Administering an angiotensin-converting enzyme inhibitor like enalapril will reduce systemic hypertension and preserve renal function. Assessing the arteriovenous fistula is an important nursing intervention to preserve the patency of the fistula and reduce the risk of infection, not preserve renal perfusion. The kidney with chronic disease is unable to excrete protein by-products, causing the multisystemic effects of uremia. Monitoring the client's protein intake will address these effects but does not directly preserve renal perfusion. An increase in white blood cells can indicate infection but does not directly affect renal perfusion.)
The nurse knows that preserving renal perfusion is important in the care of a client with chronic renal disease. Which intervention supports this principle? a Administering an angiotensin-converting enzyme inhibitor per orders b Monitoring the client's protein intake c Assessing the arteriovenous fistula on every shift d Monitoring the white blood cell count
a
The nurse on a medical-surgical unit completes the shift assessment for a client diagnosed with a multisystem fluid volume deficit and documents that the client is experiencing the following symptoms: tachycardia; pale, cool skin; and a decreased urine output. The nurse knows that these symptoms are caused by: a The body's natural compensatory mechanisms. b Effects of rapidly infused intravenous fluids. c Cardiac failure. d Pharmacological effects of a diuretic.
a,b,e

What is the most important nursing interventions to prevent acute renal failure in a critically ill client? a Maintaining fluid volume and cardiac output. b Avoiding all potentially nephrotoxic drugs. c Assessing for a history of diabetes or systemic lupus erythematosus. d Administering antihypertensive drugs.
Subcutaneously
When IV access is problematic, fluids can be administered ________ a method called hypodermoclysis
d (Rationale: In fluid volume deficit, there is less volume in the vascular system, which decreases venous return and cardiac output, leading to manifestations of dizziness, orthostatic hypotension, and flat neck veins. The heart rate increases and the blood pressure falls. Dyspnea and crackles usually are associated with excess fluid volume. Headache and muscle cramps are often due to electrolyte imbalance, not fluid loss.)
When assessing a client with fluid volume deficit, the nurse would assess for which of the following s/sx? a Headache and muscle cramps. b Increased pulse rate and blood pressure. c Dyspnea and respiratory crackles. d Orthostatic hypotension and flat neck veins.
d
When assessing a client with fluid volume deficit, the nurse would expect to find: a Dyspnea and respiratory crackles. b Increased pulse rate and blood pressure. c Headache and muscle cramps. d Orthostatic hypotension and flat neck veins.
b
When caring for a client with acute renal failure, the nurse would plan which treatment goal for the client? a Increase fluids to prevent nephrolithiasis. b Compensate for renal impairment by restoring fluid balance. c Maintain adequate nutrition by encouraging a high-protein and high-calorie diet. d Prevent infection by administering antibiotics.
c
When engaging the client in the plan of care for end stage renal disease, to what should the nurse pay particular attention? a Medication regimens and their side effects b Weighing client daily c Meal planning when dietary modifications are required d Monitoring input and output
d (Chronic hypertension can lead to chronic renal failure because of sclerotic changes in the renal arterioles that reduce blood flow and cause ischemia and glomerular destruction. Cystitis, or bladder infection, will not lead to chronic renal failure because the infection is distal to the kidneys. COPD and CAD do not affect renal function.)
Which chronic health conditions can lead to progressive renal failure? a Cystitis b Chronic obstructive pulmonary disease (COPD) c Coronary artery disease (CAD) d Hypertension
b,c,d,e (Major trauma, heart failure, and hemorrhage are risk factors for acute renal failure because they can reduce blood flow to the kidneys. Radiologic contrast media can be nephrotoxic and cause acute renal failure. Cerebrovascular disease is not a risk factor for acute renal failure because it does not reduce blood flow to the kidneys and it does not cause nephrotoxicity.)

diffusion
_________________ is the natural movement of molecules due to their random motion, can occur across the capillary membranes.
a ( Feedback Rationale: The client with little or no urine output is best assessed for fluid volume status by weight changes because retained fluid has weight. Lack of output would exclude intake and output as accurate data for assessment. The client's thirst does not indicate fluid status because the client on fluid restriction will be thirsty even with fluid volume excess. BUN and creatinine are used to assess kidney function; while BUN increases with dehydration, it is not the best indicator of fluid status.)
Which finding by the nurse would be an accurate indicator of fluid volume status in an oliguric or aneuric client? a Weight changes b Intake and output c BUN and creatinine levels d Level of thirst
b
Which fluid or electrolyte imbalance is best treated with dialysis? a Fluid volume deficit b Hyperkalemia c Hyponatremia d Blood loss

(Select all that apply.) a Reading food labels to note fiber content b Monitoring daily weight c Keeping track of how many cups of fluid they drink d Elevating legs and feet when sitting e Reducing intake of caffeinated drinks
c (An increasing serum potassium level is an indication for hemodialysis because of its arrhythmogenic effects. Although anemia (decreased red blood cells) and low serum sodium are associated with acute renal failure, they can be managed with therapies other than hemodialysis. Cell casts in the urine are a sign of acute tubular necrosis and cannot be reversed with hemodialysis.)
Which laboratory value is an indication for hemodialysis? a Decreased red blood cells b Low serum sodium c Increasing serum potassium level d Cell casts in urine
d
Which nursing actions are instituted for the client with kidney trauma? a Observe urine for oliguria and proteinuria. b Monitor vital signs for hypotension and bradycardia. c Monitor level of consciousness and urine output. d Observe for hypertension and check urine for hematuria.
a,b,e (Rationale Nursing care for clients with fluid volume overload caused by acute renal failure includes maintaining intake and output measurements and daily weighing to assist in tracking fluid balance. The semi-Fowler position helps improve respiratory excursion of the client with fluid overload. Clients with acute renal failure have hyperkalemia and should not be given potassium supplements. Liberal fluid intake is contraindicated in clients with acute renal failure because of their inability to excrete excess fluid.)
Which nursing intervention would be implemented for a client with fluid volume overload due to acute renal failure? (Select all that apply.) a Weighing daily b Placing in semi-Fowler position c Administering potassium replacements d Encouraging liberal fluid intake e Maintaining intake and output records
