Ch. 63 Concepts Care for Patients with Acute Kidney Injury and Chronic Kidney Disease

A client is receiving immune-suppressive therapy after kidney transplantation. Which measure for infection control is important for the nurse to implement? Adherence to therapy Handwashing Monitoring for low-grade fever Strict clean technique

Handwashing

A client admitted to the medical unit with a history of vomiting and diarrhea and an increased blood urea nitrogen requires 1 L of normal saline infused over 2 hours. Which staff member would be assigned to care for the client? LPN/LVN with experience working on the medical unit. New graduate RN who just finished a 6-week orientation. RN who has floated from pediatrics for this shift. RN who usually works on the general surgical unit.

RN who usually works on the general surgical unit.

A client is started on continuous venovenous hemofiltration (CVVH). Which finding would require immediate action by the nurse? a. Potassium level of 5.5 mEq/L (5.5 mmol/L) b. Sodium level of 138 mEq/L (138 mmol/L) c. Blood pressure of 76/58 mm Hg d. Pulse rate of 88 beats/min

ANS: C Hypotension can be a problem with CVVH if replacement fluid does not provide enough volume to maintain blood pressure. The nurse needs to monitor for ongoing fluid and electrolyte replacement. The sodium level is normal and the potassium level is slightly elevated, which could be normal findings for someone with acute kidney injury. A pulse rate of 88 beats/min is within usual limits.

A client is scheduled to undergo kidney transplant surgery. Which teaching point does the nurse include in the preoperative teaching session? "It is essential for you to wash your hands and avoid people who are ill." "The new kidney will be placed directly below one of your old kidneys." "You will receive dialysis the day before surgery and for about a week after." "Your diseased kidney will be removed when the transplant is performed."

"It is essential for you to wash your hands and avoid people who are ill."

A client has a serum potassium level of 6.5 mEq/L (6.5 mmol/L), a serum creatinine level of 2 mg/dL (176 mcmol/L), and a urine output of 350 mL/day. What is the best action by the nurse? a. Place the client on a cardiac monitor immediately. b. Teach the client to limit high-potassium foods. c. Continue to monitor the client's intake and output. d. Ask to have the laboratory redraw the blood specimen.

A potassium can cause dysrrhythmia

When caring for a client with a left forearm arteriovenous fistula created for hemodialysis, which nursing actions are required? (Select all that apply.) A) Ensure that no blood pressures are taken in that arm. B) Teach the client to palpate for a thrill over the site. C) Elevate the arm above heart level. D) Auscultate for a bruit every 8 hours. E) Check brachial pulses daily.

A B D A bruit or swishing sound and a thrill or buzzing sensation upon palpation would be present in this client, indicating patency of the fistula. No blood pressure, venipuncture, or compression, such as lying on the fistula, would occur.Distal pulses and capillary refill would be checked daily. For a forearm fistula, the radial pulse is checked instead of the brachial pulse which is proximal. Elevating the arm increases venous return, possibly collapsing the fistula.

The nurse is caring for a client following a kidney transplant. Which assessment data indicate to the nurse possible rejection of the kidney? (Select all that apply.) A) Crackles in the lung fields B) Temperature of 98.8° F (37.1° C) C) Blood pressure of 164/98 mm Hg D) Blood urea nitrogen (BUN) 21 mg/dL (7.5 mmol/L), creatinine 0.9 mg/dL (80 mcmol/L) E) 3+ edema of the lower extremities

A C E

A client is unsure of the decision to undergo peritoneal dialysis (PD) and wishes to discuss the advantages of this treatment with the nurse. Which statements by the nurse are correct regarding PD? (Select all that apply.) a. "You will not need vascular access to perform PD." b. "There is less restriction of protein and fluids." c. "You will have no risk for infection with PD." d. "You have flexible scheduling for the exchanges." e. "It takes less time than hemodialysis treatments."

A, B, D PD is based on exchanges of waste, fluid, and electrolytes in the peritoneal cavity. There is no need for vascular access. Protein is lost in the exchange, which allows for more protein and fluid in the diet. There is flexibility in the time for exchanges, but the treatment takes a longer period of time compared to hemodialysis. There still is risk for infection with PD, especially peritonitis

A client is taking furosemide 40 mg/day for management of early chronic kidney disease (CKD). To assess the therapeutic effect of the medication, what action of the nurse is best? a. Obtain daily weights of the client. b. Auscultate heart and breath sounds. c. Palpate the client's abdomen. d. Assess the client's diet history.

ANS: A Furosemide is a loop diuretic that helps reduce fluid overload and hypertension in patients with early stages of CKD. One kilogram of weight equals about 1 L of fluid retained in the client, so daily weights are necessary to monitor the response of the client to the medication. Heart and breath sounds would be assessed if there is fluid retention, as in heart failure. Palpation of the client's abdomen is not necessary, but the nurse would check for edema. The diet history of the client would be helpful to assess electrolyte replacement since potassium is lost with this diuretic, but this does not assess the effectiveness of the medication

A 70-kg adult client with chronic kidney disease (CKD) is on a 40-g protein diet. The patient has a reduced glomerular filtration rate and is not undergoing dialysis. Which result would be of most concern to the nurse? a. Albumin level of 2.5 g/dL (3.63 mcmol/L) b. Phosphorus level of 5 mg/dL (1.62 mmol/L) c. Sodium level of 135 mEq/L (135 mmol/L) d. Potassium level of 5.5 mEq/L (5.5 mmol/L

ANS: A Protein restriction is necessary with CKD due to the buildup of waste products from protein breakdown. The nurse would be concerned with the low albumin level since this indicates that the protein in the diet is not enough for the client's metabolic needs. The electrolyte values are not related to the protein-restricted die

A client with chronic kidney disease (CKD) has an elevated serum phosphorus level. What drug would the nurse anticipate to be prescribed for this client? .A Calcium acetate b. Doxycyline c. Magnesium sulfate d. Lisinopril

ANS: A The client with CKD often has a high phosphorus level which tends to lower the calcium level in an inverse relationship, and causes osteodystrophy. To prevent this bone disease, the client needs to take a drug that can bind with phosphorus for elimination via the GI tract. When phosphorus is lowered to within normal limits, normal calcium levels may be restored.

A client with chronic kidney disease (CKD) is refusing to take his medication and has missed two hemodialysis appointments. What is the best initial action for the nurse? a. Discuss what the treatment regimen means to the client. b. Refer the client to a mental health nurse practitioner. c. Reschedule the appointments to another date and time. d. Discuss the option of peritoneal dialysis.

ANS: A The initial action for the nurse is to assess anxiety, coping styles, and the client's acceptance of the required treatment for CKD. The client may be in denial of the diagnosis. While rescheduling hemodialysis appointments may help, and referral to a mental health practitioner and the possibility of peritoneal dialysis are all viable options, assessment of the client's acceptance of the treatment would come first

The nurse is caring for five clients on the medical-surgical unit. Which clients would the nurse consider to be at risk for postrenal acute kidney injury (AKI)? (Select all that apply.) a. Client with prostate cancer b. Client with blood clots in the urinary tract c. Client with ureterolithiasis d. Client with severe burns e. Client with lupus

ANS: A, B, C Urine flow obstruction, such as prostate cancer, blood clots in the urinary tract, and kidney stones (ureterolithiasis), causes postrenal AKI. Severe burns would be a prerenal cause. Lupus would be an intrarenal cause for AKI

A client is undergoing hemodialysis. The client's blood pressure at the beginning of the procedure was 136/88 mm Hg, and now it is 110/54 mm Hg. What actions would the nurse perform to maintain blood pressure? (Select all that apply.) a. Adjust the rate of extracorporeal blood flow. b. Place the patient in the Trendelenburg position. c. Stop the hemodialysis treatment. d. Administer a 250-mL bolus of normal saline. e. Contact the primary health care provider

ANS: A, B, D Hypotension occurs often during hemodialysis treatments as a result of vasodilation from the warmed dialysate. Modest decreases in blood pressure, as is the case with this client, can be maintained with rate adjustment, Trendelenburg positioning, and a fluid bolus. If the blood pressure drops considerably after two boluses and cooling dialysate, the hemodialysis can be stopped and the primary health care provider contacted

A client is hospitalized in the oliguric phase of acute kidney injury (AKI) and is receiving tube feedings. The nurse is teaching the client's spouse about the renal-specific formulation for the enteral solution compared to standard formulas. What components would be discussed in the teaching plan? (Select all that apply.) a. Lower sodium b. Higher calcium c. Lower potassium d. Higher phosphorus e. Higher calories

ANS: A, C, E Many clients with AKI are too ill to meet caloric goals and require tube feedings with renal-specific formulas that are lower in sodium, potassium, and phosphorus, and higher in calories than are standard formulas.

A nurse is caring for a postoperative 70-kg client who had major blood loss during surgery. Which findings by the nurse would prompt immediate action to prevent acute kidney injury? (Select all that apply.) a. Urine output of 100 mL in 4 hours b. Urine output of 500 mL in 12 hours c. Large amount of sediment in the urine d. Amber, odorless urine

ANS: A, C, E The low urine output, sediment, and blood pressure would be reported to the primary health care provider. Postoperatively, the nurse would measure intake and output, check the characteristics of the urine, and report sediment, hematuria, and urine output of less than 0.5 mL/kg/hr for 3 to 4 hours. A urine output of 100 mL is low, but a urine output of 500 mL in 12 hours would be within normal limits. Perfusion to the kidneys is compromised with low blood pressure. The amber odorless urine is normal

A client is having a peritoneal dialysis treatment. The nurse notes an opaque color to the effluent. What is the priority action by the nurse? a. Warm the dialysate solution in a microwave before instillation. b. Obtain a sample of the effluent and send to the laboratory. c. Flush the tubing with normal saline to maintain patency of the catheter. d. Check the peritoneal catheter for kinking and curling.

ANS: B An opaque or cloudy effluent is the first sign of peritonitis. A sample of the effluent would need to be sent to the laboratory for culture and sensitivity in order to administer the correct antibiotic. Warming the dialysate in a microwave and flushing the tubing are not safe actions by the nurse. Checking the catheter for obstruction is a viable option but will not treat the peritonitis

The nurse is caring for four clients with chronic kidney disease (CKD). Which client would the nurse assess first upon initial rounding? Test Bank for Medical Surgical Nursing 10th Edition Ignatavicius (Test Bank PDF Files) GARDESLAB.COM G R A D E S L A B . C O M a. Client with a blood pressure of 158/90 mm Hg b. Client with Kussmaul respirations c. Client with skin itching from head to toe d. Client with halitosis and stomatiti

ANS: B Kussmaul respirations indicate that the client has metabolic acidosis which is a complication of CKD. The client is increasing the rate and depth of breathing to excrete carbon dioxide through the lungs to lower serum pH. Hypertension is common in most patients with CKD, and skin itching increases with calcium-phosphate imbalances and elevations of nitrogenous wastes, another common finding in CKD. Uremia from CKD causes ammonia to be formed, resulting in the common findings of halitosis and stomatitis

The nurse is assessing a client with a diagnosis of prerenal acute kidney injury (AKI). Which condition would the nurse expect to find in the patient's recent history? a. Pyelonephritis b. Dehydration c. Bladder cancer d. Kidney stones

ANS: B Prerenal causes of AKI are related to a decrease in perfusion, such as in clients who have prolonged dehydration. Pyelonephritis is an intrinsic or intrarenal cause of AKI related to kidney damage. Bladder cancer and kidney stones are postrenal causes of AKI related to urine flow obstruction.

A nurse is giving discharge instructions to a client recently diagnosed with chronic kidney disease (CKD). Which statements made by the client indicate a correct understanding of the teaching? (Select all that apply.) a. "I can continue to take antacids to relieve heartburn." b. "I need to ask for an antibiotic when scheduling a dental appointment." c. "I'll need to check my blood sugar often to prevent hypoglycemia." d. "The dose of my pain medication may have to be adjusted." e. "I should watch for bleeding when taking my anticoagulants.

ANS: B, C, D, E In discharge teaching, the nurse must emphasize that the client needs to have an antibiotic prophylactically before dental procedures to prevent infection. There may be a need for dose reduction in medications if the kidney is not excreting them properly (antacids with magnesium, antibiotics, antidiabetic drugs, insulin, opioids, and anticoagulants

The nurse is caring for a client with a new diagnosis of chronic kidney disease. Which priority complications would the nurse anticipate? (Select all that apply.) a. Dehydration b. Anemia c. Hypertension d. Dysrhythmias e. Heart failure

ANS: B, C, D, E The client who has CKD has fluid overload and electrolyte imbalances, especially hyperkalemia, that can cause hypertension, heart failure, and dysrhythmias. Anemia results because erythropoietin production by the kidneys is decreased.

A client with diabetes mellitus type 2 has been well controlled with metformin. The client is scheduled for magnetic resonance imaging (MRI) scan with contrast. What priority would the nurse take at this time? a. Teach the client about the purpose of the MRI. b. Assess the client's blood urea nitrogen and creatinine. c. Tell the client to withhold metformin for 24 hours before the MRI

ANS: C Contrast media can be nephrotoxic (damaging to the kidneys). Metformin can also be nephrotoxic and the client should not be exposed to two agents. Clients who have diabetes are already at risk for renal damage

The nurse is teaching a client how to increase the flow of dialysate into the peritoneal cavity during dialysis. Which statement by the client demonstrates a correct understanding of the teaching? a. "I should leave the drainage bag above the level of my abdomen." b. "I could flush the tubing with normal saline if the flow stops." c. "I should take a stool softener every morning to avoid constipation." d. "My diet should have low fiber in it to prevent any irritation.

ANS: C Inflow and outflow problems of the dialysate are best controlled by preventing constipation. A daily stool softener is the best option for the client. The drainage bag should be below the level of the abdomen. Flushing the tubing will not help with the flow. A diet high in fiber will also help with a constipation problem

A client is placed on fluid restriction because of chronic kidney disease (CKD). Which assessment finding would alert the nurse that the client's fluid balance is stable at this time? a. Decreased calcium levels b. Increased phosphorus levels c. No adventitious sounds in the lungs d. Increased edema in the legs

ANS: C The absence of adventitious sounds upon auscultation of the lungs indicates a lack of fluid overload and fluid balance in the client's body. Decreased calcium levels and increased phosphorus levels are common findings with CKD. Edema would indicate a fluid imbalance.

The nurse is teaching assistive personnel (AP) about fluid restriction for a client who has acute kidney injury (AKI). The client's 24-hour urinary output is 120 mL. How much fluid would the client be allowed to have over the next 24 hours? a. 380 mL b. 500 mL c. 620 mL d. 750 mL

ANS: C The general principle for fluid restriction for clients is that they may have a daily fluid intake of 500 mL plus the amount of their urinary output. In this case, 120 mL urinary output plus 500 mL equals 620 mL fluid allowance

The charge nurse is orienting a new nurse about care for an assigned client with an arteriovenous (AV) fistula for hemodialysis in her left arm. Which action by the float nurse would be considered unsafe? a. Palpating the access site for a bruit or thrill b. Using the right arm for a blood pressure reading c. Administering intravenous fluids through the AV fistula d. Checking distal pulses in the left arm

ANS: C The nurse would not use the arm with the AV fistula for intravenous infusion, blood pressure readings, or venipuncture. Compression and infection can result in the loss of the AV fistula. The AV fistula would be monitored by auscultating or palpating the access site. Checking the distal pulse would be an appropriate assessment.

The nurse is teaching a client with chronic kidney disease (CKD) about the sodium restriction needed in the diet to prevent edema and hypertension. Which statement by the client indicates that more teaching is needed? a. "I will probably lose weight by cutting out potato chips." b. "I will cut out bacon with my eggs every morning." c. "My cooking style will change by not adding salt." d. "I am thrilled that I can continue to eat fast food."

ANS: D Fast-food restaurants usually serve food that is high in sodium. This statement indicates that more teaching needs to occur. The other statements show a correct understanding of the teaching.

A client with acute kidney injury (AKI) has a blood pressure of 76/55 mm Hg. The primary health care provider prescribed 1000 mL of normal saline to be infused over 1 hour to maintain perfusion. The client starts to develop shortness of breath. What is the nurse's priority action? a. Calculate the mean arterial pressure (MAP). b. Ask for insertion of a pulmonary artery catheter. c. Take the client's pulse. d. Decrease the rate of the IV infusion.

ANS: D The nurse would assess that the client could be developing fluid overload and respiratory distress and slow down the normal saline infusion. The calculation of the MAP also reflects perfusion. The insertion of a pulmonary artery catheter would evaluate the client's hemodynamic status, but this would not be the initial or priority action by the nurse. Vital signs are also important after adjusting the intravenous infusion

A client with chronic kidney disease reports chest pain. The nurse notes tachycardia and low-grade fever. Which additional assessment is warranted? Monitor for decreased peripheral pulses. Determine if the client is able to ambulate. Auscultate for pericardial friction rub. Assess for crackles.

Auscultate for pericardial friction rub. The additional assessment needed for the client with uremia is to auscultate the pericardium for friction rub. Clients with CKD are prone to pericarditis. Signs/symptoms of pericarditis include inspiratory chest pain, tachycardia, narrow pulse pressure, low-grade fever, and pericardial friction rub.

A client with a recently created vascular access for hemodialysis is being discharged. Which teaching will the nurse include in the discharge instructions? How to practice proper nutrition? Avoiding venipuncture and blood pressure measurements in the affected arm How to assess for a bruit in the affected arm? Modifications to allow for complete rest of the affected arm

Avoid venipuncture and BP measurement in affected arm The nurse must teach the client to avoid venipunctures and blood pressure measures in the arm that contains the newly created vascular access device. Compression of vascular access causes decreased blood flow and may cause occlusion. If this occurs, lifesaving dialysis will not be possible.

While managing care for a client with chronic kidney disease, which action does the registered nurse (RN) plan to delegate to assistive personnel (AP)? (Select all that apply.) A) Explain the components of a low-sodium diet. B) Document the amount the client drinks throughout the shift. C) Auscultate the client's lung sounds every 4 hours. D)Check the arteriovenous (AV) fistula for a thrill and bruit. E) Obtain the client's prehemodialysis weight.

B E

The nurse is teaching dietary modification to a client with acute kidney injury (AKI). What dietary teaching will the nurse include? (Select all that apply.) A) liberal sodium B) low fat C) restricted fluids D) restricted protein e) low potassium

C D E A client with acute kidney injury needs to modify the diet to include restricted protein, restricted fluids, and low potassium.

To prevent prerenal acute kidney injury, which person will the nurse encourage to increase fluid consumption? Office secretary Construction worker School teacher Taxicab driver

Construction worker

The nurse administers epoetin alfa to a client who has chronic kidney disease (CKD). Which laboratory test value would the nurse monitor to determine this drug's effectiveness? a. Potassium b. Sodium c. Renin d. Hemoglobin

D The purpose of giving epoetin alfa to a client with CKD is to manage anemia by stimulating the bone marrow to produce more red blood cells. Therefore, monitoring the client's hemoglobin, hematocrit, and red blood cell count would indicate if the drug was effective.

The nurse is caring for client who is receiving erythropoietin. Which assessment finding indicates a positive response to the medication? A decrease in fatigue Potassium in normal range Absence of spontaenous fractures Hematocrit of 26.7

Decrease in fatigue

A client with end-stage kidney disease has been placed on fluid restrictions. Which assessment data indicates to the nurse that the fluid restriction has not been followed? Dyspnea and anxiety at rest Blood pressure of 118/78 mm Hg Central venous pressure (CVP) of 6 mm Hg Weight loss of 3 lb (1.4 kg) during hospitalization

Dyspnea and anxiety at rest The assessment finding that shows that the client has not adhered to fluid restriction is dyspnea and anxiety at rest. Dyspnea is a sign of fluid overload and possible pulmonary edema. The nurse needs to assist the client in correlating symptoms of fluid overload with nonadherence to fluid restriction.

When assisting with dietary protein needs for a client on peritoneal dialysis, the nurse recommends which food selection? Eggs Ham Eggplant Macaroni

Eggs The nurse recommends eggs as a dietary protein need for a client on peritoneal dialysis. Other suggested protein-containing foods for this client are milk and meat.Although a protein, ham is high in sodium and needs to be avoided. Vegetables and pasta contain mostly carbohydrates. Peritoneal dialysis clients are allowed 1.2 to 1.5 g of protein/kg/day because protein is lost with each exchange.

The nurse is caring for a client with kidney failure. Which assessment data indicates the need for increased fluids? Decreased sodium level Pale-colored urine Increased blood urea nitrogen (BUN) Increased creatinine level

Increased blood urea nitrogen (BUN) An increase in BUN can be an indication of dehydration, and a needed increase in fluids.Increased creatinine indicates kidney impairment.

A client comes into the emergency department with a serum creatinine of 2.2 mg/dL (1944 mcmol/L) and a blood urea nitrogen (BUN) of 24 mL/dL (8.57 mmol/L). What question would the nurse ask first when taking this client's history? a. "Have you been taking any aspirin, ibuprofen, or naproxen recently?" b. "Do you have anyone in your family with renal failure?" c. "Have you had a diet that is low in protein recently?" d. "Has a relative had a kidney transplant lately?

M ANS: A There are some medications that are nephrotoxic, such as the nonsteroidal anti-inflammatory drugs ibuprofen, aspirin, and naproxen. This would be a good question to initially ask the patient since both the serum creatinine and BUN are elevated, indicating some renal problems. A diet high in protein could be a factor in an increased BUN.

A client is admitted with acute kidney injury (AKI) and a urine output of 2000 mL/day. What is the major concern of the nurse regarding this patient's care? a. Edema and pain b. Cardiac and respiratory status c. Electrolyte and fluid imbalance d. Mental health statu

NS: C This client may have an inflammatory cause of AKI with proteins entering the glomerulus and holding the fluid in the filtrate, causing polyuria. Electrolyte loss and fluid balance are essential. Edema and pain are not usually a problem with fluid loss. There could be changes in the client's cardiac, respiratory, and mental health status if the electrolyte imbalance is not treated

The nurse teaches a client who is recovering from acute kidney injury to avoid which type of medication? Opioids NSAIDS Calcium channel blockers ACE inhibitors

NSAIDs can be nephrotoxic

The nurse is caring for a client with acute kidney injury and a temporary subclavian hemodialysis catheter. Which assessment finding requires nursing action? Mild discomfort at the insertion site Temperature 100.8° F (38.2° °C) Anorexia 1+ ankle edema

Temperature 100.8° F (38.2° °C) In this client situation, the nurse reports an assessment finding of a temperature of 100.8° F (38.2° C) to the HCP. Infection is a major complication of temporary catheters. All symptoms of infection, including fever, must be reported to the provider because the catheter may have to be removed.Mild discomfort at the insertion site is expected with a subclavian hemodialysis catheter. During acute injury, oliguria with resulting fluid retention and 1+ ankle edema is expected. Rising blood urea nitrogen may result in anorexia, nausea, and vomiting.

A marathon runner comes into the clinic and states "I have not urinated very much in the last few days." The nurse notes a heart rate of 110 beats/min and a blood pressure of 86/58 mm Hg. Which action by the nurse is most appropriate? a. Give the client a bottle of water immediately. b. Start an intravenous line for fluids. c. Teach the patient to drink 2 to 3 L of water daily. d. Perform an electrocardiogram

This athlete is mildly dehydrated as evidenced by the higher heart rate and lower blood pressure. The nurse can start hydrating the client with a bottle of water first, followed by teaching the patient to drink 2 to 3 L of water each day. An intravenous line may be needed later, after the patient's degree of dehydration is assessed. An electrocardiogram is not necessary at this time

Which client will the nurse assess as at risk for acute kidney injury (AKI)? (Select all that apply.) A Client in the intensive care unit on high doses of antibiotics B Football player in preseason practice C Accident victim recovering from a severe hemorrhage D Accountant with poorly controlled diabetes mellitus E Client who underwent contrast dye radiology F Client recovering from gastrointestinal influenza

When caring for a client who receives peritoneal dialysis (PD), which finding does the nurse report to the provider (HCP) immediately? Temperature of 101.2° F (38.4° C) Sinus bradycardia, rate of 58 beats/min Pulse oximetry reading of 95% Blood pressure of 148/90 mm Hg

he nurse needs to immediately report a peritoneal dialysis client's temperature of 101.2° F (38.4° C) to the HCP. Peritonitis is the major complication of PD, caused by intra-abdominal catheter site contamination. Meticulous aseptic technique must be used when caring for PD equipment
