Fluid intake is monitored during the oliguric phase. Fluid intake is determined by adding all losses for the previous 24 hours plus 600 mL. Potassium and protein intake may be limited in the oliguric phase to avoid hyperkalemia and elevated urea nitrogen. Hemodialysis, not peritoneal dialysis, is indicated in acute kidney injury if dialysis is needed. - Exact Answer The nurse is caring for a 68-yr-old man who had coronary artery bypass surgery 3 weeks ago. During the oliguric phase of acute kidney disease, which action would be appropriate to include in the plan of care? a. Provide foods high in potassium. b. Restrict fluids based on urine output. c. Monitor output from peritoneal dialysis. d. Offer high-protein snacks between meals. A. assess skin turgor to determine hydration status

Preexisting kidney disease is the most important risk factor for the development of contrast-associated nephropathy and nephrotoxic injury. If contrast media must be administered to a high-risk patient, the patient needs to have optimal hydration. The nurse should assess the hydration status of the patient before the procedure is performed. Indwelling catheter use should be avoided whenever possible to decrease the risk of infection. - Exact Answer A 52-yr-old man with stage 2 chronic kidney disease is scheduled for an outpatient diagnostic procedure using contrast media. Which priority action should the nurse perform? a. Assess skin turgor to determine hydration status. b. Insert a urinary catheter for the expected diuresis. c. Evaluate the patient's lower extremities for edema. d. Check the patient's urine for the presence of ketones.

C. Cardiac dysrhythmias Hyperkalemia is the most serious electrolyte disorder associated with kidney disease. Fatal dysrhythmias can occur when the serum potassium level reaches 7 to 8 mEq/L. Fatigue and hypertriglyceridemia may be present but do not require urgent intervention. Hypoglycemia is a complication related to diabetes control, not hyperkalemia. However, administration of insulin and dextrose is an emergency treatment for hyperkalemia. - Exact Answer A 56-yr-old woman with type 2 diabetes mellitus and chronic kidney disease has a serum potassium level of 6. mEq/L. Which finding will the nurse monitor for? a. Fatigue b. Hypoglycemia c. Cardiac dysrhythmias

d. Elevated triglycerides D. aluminum hydroxide Antacids (that contain magnesium and aluminum) should be avoided because patients with kidney disease are unable to excrete these substances. Also, some antacids contain high levels of sodium that further increase blood pressure. Acetaminophen and aspirin (if taken for a short period of time) are usually safe for patients with kidney disease. Antihistamines may be used, but combination drugs that contain pseudoephedrine may increase blood pressure and should be avoided. - Exact Answer A frail 72-yr-old woman with stage 3 chronic kidney disease is cared for at home by her family. The patient has a history of taking many over-the-counter medications. Which over-the- counter medications should the nurse teach the patient to avoid? a. Aspirin

b. "The fluid draining from the catheter is cloudy." c. "The drainage is bloody when I have my period." d. "I wash around the catheter with soap and water." d. phosphorus Phosphorus and calcium have inverse or reciprocal relationships, meaning that when phosphorus levels are high, calcium levels tend to be low. Therefore, administration of calcium should help to reduce a patient's abnormally high phosphorus level, as seen with CKD. Calcium acetate will not have an effect on sodium, potassium, or magnesium levels. - Exact Answer The nurse preparing to administer a dose of calcium acetate to a patient with chronic kidney disease (CKD). Which laboratory result will the nurse monitor to determine if the desired effect was achieved?

a. Sodium b. Potassium c. Magnesium d. Phosphorus D. restrict fluids according to previous daily loss. Patients in the oliguric phase of AKI will have fluid volume excess with potassium and sodium retention. Therefore, they will need to have dietary sodium, potassium, and fluids restricted. Daily fluid intake is based on the previous 24-hour fluid loss (measured output plus 600 mL for insensible loss). The diet also needs to provide adequate, not low, protein intake to prevent catabolism. The patient should also be weighed daily, not just three times each week. - Exact Answer When caring for a patient during the oliguric phase of acute kidney injury (AKI), which nursing action is appropriate?

a. Weigh patient three times weekly. b. Increase dietary sodium and potassium. c. Provide a low-protein, high-carbohydrate diet. d. Restrict fluids according to previous daily loss. B. "It is essential that you maintain aseptic technique to prevent peritonitis." Peritonitis is a potentially fatal complication of peritoneal dialysis, and thus it is imperative to teach the patient methods of prevention. Although the other teaching statements are accurate, they do not have the potential for morbidity and mortality that peritonitis does. - Exact Answer Which statement regarding continuous ambulatory peritoneal dialysis (CAPD) would be most important when teaching a patient new to the treatment?

a. Hypokalemia b. Hyponatremia c. Large urine output d. Leukocytosis with cloudy urine output D. dissecting abdominal aortic aneurysm A dissecting abdominal aortic aneurysm is a prerenal cause of AKI because it can decrease renal artery perfusion and therefore the glomerular filtrate rate. Aminoglycoside antibiotic administration, a hemolytic blood transfusion reaction, and post-streptococcal glomerulonephritis are intrarenal causes of AKI. - Exact Answer Which patient diagnosis or treatment is most consistent with prerenal acute kidney injury (AKI)?

a. IV tobramycin b. Incompatible blood transfusion c. Poststreptococcal glomerulonephritis d. Dissecting abdominal aortic aneurysm A. monitor the patient's cardiac status The nurse's priority is to monitor the patient's cardiac status. With the rapidly progressing glomerulonephritis, renal function begins to fail and fluid, potassium, and hydrogen retention lead to hypervolemia, hyperkalemia, and metabolic acidosis. Excess fluid increases the workload of the heart, and hyperkalemia can lead to life-threatening dysrhythmias. Teaching about hand washing and observation of the patient are important nursing interventions but are not the priority. Electrolyte measurement is a collaborative intervention that will be done as ordered by the health care provider. - Exact Answer The patient

has rapidly progressing glomerular inflammation. Weight has increased and urine output is steadily declining. What is the priority nursing intervention? a. Monitor the patient's cardiac status. b. Teach the patient about hand washing. c. Obtain a serum specimen for electrolytes. d. Increase direct observation of the patient. d. Calculated glomerular filtration rate (GFR) The best study to determine kidney function or CKD that would be expected in the patient with diabetes is the calculated GFR that is obtained from the patient's age, gender, race, and serum creatinine. It would need to be abnormal for 3 months to establish a diagnosis of CKD. A creatinine clearance test done with a blood sample and a 24-

hour urine collection is also important. Serum creatinine is not the best test for CKD because the level varies with different patients. Serum potassium levels could explain why the patient has an irregular heartbeat. The finding of microalbuminuria can alert the patient with diabetes about potential renal involvement and potentially failing kidneys. However, urine albumin levels are not used for diagnosis of CKD. - Exact Answer A patient with a 25-year history of type 1 diabetes mellitus is reporting fatigue, edema, and an irregular heartbeat. On assessment, the nurse notes newly developed hypertension and uncontrolled blood sugars. Which diagnostic study is most indicative of chronic kidney disease (CKD)? a. Serum creatinine b.

B. a 61 year old native american man with diabetes The nurse identifies the 61-yr-old Native American with diabetes as the most at risk. Diabetes causes about 50% of CKD. This patient is the oldest, and Native Americans with diabetes develop CKD six times more frequently than other ethnic groups. Hypertension causes about 25% of CKD. Hispanics have CKD about 1.5 times more than non-Hispanics. African Americans have the highest rate of CKD because hypertension is significantly increased in African Americans. A UTI will not cause CKD unless it is not treated or UTIs occur recurrently. - Exact Answer Which patient has the most significant risk factors for CKD? a. A 50-yr-old white woman with hypertension b. A 61-yr-old Native American man with diabetes c. A 40-yr-old Hispanic woman with cardiovascular disease

d. A 28-yr-old African American woman with a urinary tract infection B. increasing osmolality of the dialysate. Ultrafiltration in peritoneal dialysis is achieved by increasing the osmolality of the dialysate with additional glucose. In hemodialysis, the increased pressure gradient from increased pressure in the blood compartment or decreased pressure in the dialysate compartment causes ultrafiltration. Decreasing the concentration of the dialysate in either peritoneal or hemodialysis will decrease the amount of fluid removed from the blood stream. - Exact Answer Diffusion, osmosis, and ultrafiltration occur in both hemodialysis and peritoneal dialysis. Which strategy is used to achieve ultrafiltration in peritoneal dialysis? a. Increasing the pressure gradient b. Increasing osmolality of the dialysate

The rate and volume of fluid removal will be decreased, and 0.9% saline solution may be infused. Hypertonic saline is not used because of the high sodium load. A blood transfusion is not indicated. Antiemetic medications may help the nausea but would not help the hypovolemia. - Exact Answer During hemodialysis, the patient develops light-headedness and nausea. What should the nurse do first? a. Administer hypertonic saline. b. Administer a blood transfusion. c. Decrease the rate of fluid removal. d. Administer antiemetic medications.

B. encourage even a short walk to avoid complications of surgery Because ambulating will improve bowel, lung, and kidney function with improved circulation, even a short walk with assistance should be encouraged after pain medication. The transplant psychologist or social worker's role is to determine if the patient is emotionally stable enough to handle donating a kidney; postoperative care is the nurse's role. Trying to shame the patient into walking by telling her that other patients have not refused and telling the patient she is lucky she did not have an open nephrectomy (implying how much more pain she would be having if it had been open) will not be beneficial to the patient or her postoperative recovery. - Exact Answer A 24-yr-old woman donated a kidney via a laparoscopic donor nephrectomy to a nonrelated recipient. The patient is experiencing significant pain and refuses to get up to walk. How should the nurse respond?

C. continuous venovenous hemofiltration (cvvc) CVVH removes large volumes of water and solutes from the patient over a longer period of time by using ultrafiltration and convection. HD three times per week would not be used for this patient because fluid and solutes build up and then are rapidly removed. With APD (used at night instead of during the day) fluid and solutes build up during the day and would not benefit this patient as much. CAPD will not as rapidly remove large amounts of fluid as CVVH can do. - Exact Answer The physician has decided to use renal replacement therapy to remove large volumes of fluid from a patient who is hemodynamically unstable in the

When the kidney fails, erythropoietin in not excreted, so anemia is expected. Hypocalcemia from chronic renal disease stimulates the parathyroid to release parathyroid hormone, causing calcium liberation from bones increasing the risk of pathological fracture. Dehydration and hypercalcemia are not expected in chronic renal disease. Fluid volume overload and hypocalcemia are expected. Although impaired immune function should be expected, elevated white blood cells would indicate inflammation or infection not associated with chronic renal failure itself but a complication. - Exact Answer Which findings will the nurse expect when caring for a patient with chronic kidney disease (CKD) (select all that apply.)? a. Anemia b. Dehydration c. Hypertension d. Hypercalcemia e. Increased risk for fractures
