Question

A nurse is caring for a client who has chronic renal disease and is receiving therapy with epoetin alfa. Which of the following laboratory results should the nurse review for an indication of a therapeutic effect of the medication?

Answer 1

Correct Answers:

The hematocrit (Hct)

Rationale :

🖊️ Epoetin alfa is an erythropoiesis-stimulating agent that promotes the production of red blood cells (RBCs) in the bone marrow.

🖊️ Clients with chronic kidney disease commonly develop anemia because damaged kidneys produce insufficient endogenous erythropoietin.

🖊️ Epoetin alfa acts similarly to natural erythropoietin and stimulates erythroid progenitor cells to increase RBC production.

🖊️ Increased RBC production causes the client's hemoglobin and hematocrit levels to rise.

🖊️ Monitoring the hematocrit therefore provides evidence of whether the medication is producing its intended therapeutic response.

🖊️ Successful treatment improves the blood's oxygen-carrying capacity and can reduce manifestations such as fatigue and weakness.

🖊️ Hemoglobin and hematocrit should be monitored carefully because an excessive rise can increase the risk of hypertension and thromboembolic complications.

🖊️ Therefore, an appropriate increase in hematocrit indicates a therapeutic response to epoetin alfa.

Answer 2

Correct Answers:

Nausea and vomiting

Rationale :

🖍️ Peritonitis is a serious complication of peritoneal dialysis caused by infection and inflammation of the peritoneal membrane.

🖍️ Nausea and vomiting are common systemic and gastrointestinal manifestations of peritonitis.

🖍️ Clients can also develop abdominal pain, tenderness, fever, and abdominal distention as the infection progresses.

🖍️ A particularly important finding during peritoneal dialysis is cloudy dialysate effluent, which strongly suggests peritoneal infection.

🖍️ Contamination during catheter connections or exchanges can introduce microorganisms into the peritoneal cavity.

🖍️ Suspected peritonitis requires prompt evaluation because untreated infection can lead to sepsis and impaired peritoneal membrane function.

🖍️ The nurse should assess the dialysate drainage and obtain appropriate cultures when peritonitis is suspected.

🖍️ Therefore, nausea and vomiting are the manifestations among these options that the nurse should recognize as possible evidence of peritonitis.

Answer 3

Correct Answers:

Hyperkalemia

Rationale :

📘 During the oliguric phase of acute kidney injury (AKI), urine output decreases significantly because the kidneys cannot adequately filter and excrete waste products.

📘 Reduced renal excretion causes potassium to accumulate in the bloodstream, resulting in hyperkalemia.

📘 Hyperkalemia is one of the most dangerous complications of AKI because it can cause life-threatening cardiac dysrhythmias.

📘 Electrocardiographic changes associated with increasing potassium can include peaked T waves, prolonged PR intervals, and widened QRS complexes.

📘 The oliguric phase can also cause fluid overload, metabolic acidosis, and accumulation of nitrogenous wastes.

📘 Laboratory findings typically demonstrate increasing serum creatinine and blood urea nitrogen (BUN) as renal filtration declines.

📘 The nurse should closely monitor serum potassium, cardiac rhythm, fluid balance, daily weight, and urine output during this phase.

📘 Therefore, hyperkalemia is an expected finding during the oliguric phase of acute kidney injury.

Answer 4

Correct Answers:

Tomatoes
Raisins
Bananas

Rationale :

✅ Tomatoes

📗 Tomatoes and tomato products are important sources of potassium.

📗 Clients with chronic kidney disease can have difficulty excreting potassium because of reduced renal function.

📗 Potassium accumulation can result in hyperkalemia, which can interfere with normal cardiac conduction.

📗 Tomato products such as tomato sauce, paste, and juice can provide particularly concentrated amounts of potassium.

📗 Limiting high-potassium foods helps prevent excessive increases in the client's serum potassium level.

📗 Severe hyperkalemia can cause muscle weakness and potentially life-threatening cardiac dysrhythmias.

📗 The client's actual potassium restriction should be individualized according to kidney function and serum potassium levels.

📗 Therefore, tomatoes are a food the client should identify as high in potassium.

✅ Raisins

📗 Raisins are dried fruit and contain a concentrated amount of potassium.

📗 Removing water during the drying process concentrates nutrients and minerals within a relatively small serving size.

📗 Clients can therefore consume substantial potassium from raisins without eating a large volume of food.

📗 Chronic kidney disease reduces the kidneys' ability to eliminate excess potassium from the bloodstream.

📗 Potassium retention increases the risk for hyperkalemia as renal function declines.

📗 Hyperkalemia can cause dangerous changes in cardiac electrical conduction and rhythm.

📗 Dried fruits such as raisins are therefore commonly limited when a client requires a low-potassium renal diet.

📗 Therefore, raisins should be avoided or restricted according to the client's prescribed potassium allowance.

✅ Bananas

📗 Bananas are widely recognized as a high-potassium food.

📗 Normally, the kidneys maintain potassium balance by eliminating excess potassium through the urine.

📗 Chronic kidney disease can impair this process and cause potassium to accumulate in the blood.

📗 Excessive potassium intake can consequently increase the client's risk for hyperkalemia.

📗 Significant hyperkalemia can cause muscle weakness, conduction abnormalities, and cardiac dysrhythmias.

📗 Clients requiring potassium restriction are commonly instructed to limit foods such as bananas, oranges, potatoes, tomatoes, and dried fruits.

📗 Dietary potassium restrictions should still be individualized according to the client's laboratory results and stage of kidney disease.

📗 Therefore, bananas should be identified as a high-potassium food to avoid or limit.

Answer 5

Correct Answers:

Daily weight

Rationale :

🌹 Daily weight is the most reliable routine measure of changes in fluid volume status.

🌹 Changes in body weight over a short period primarily reflect changes in body fluid, rather than changes in fat or muscle mass.

🌹 Approximately 1 kg (2.2 lb) of weight change corresponds to about 1 L of fluid gained or lost.

🌹 Clients with chronic kidney disease (CKD) have impaired ability to excrete sodium and water, increasing their risk for fluid retention.

🌹 Daily weights can identify fluid accumulation before more obvious manifestations such as severe edema or respiratory distress develop.

🌹 The client should be weighed at the same time each day, preferably in the morning after voiding and before breakfast.

🌹 Using the same scale and similar clothing improves the accuracy of comparisons between measurements.

🌹 Therefore, daily weight provides the most reliable measurement of fluid retention among the options provided.

Answer 6

Correct Answers:

Vancomycin

Rationale :

✨ Vancomycin is an antibiotic with recognized potential to cause nephrotoxicity, particularly in clients with preexisting kidney impairment.

✨ Nephrotoxicity can result in acute kidney injury (AKI) and further deterioration of renal function.

✨ Clients with chronic kidney disease (CKD) are particularly vulnerable because their renal clearance is already reduced.

✨ Vancomycin is primarily eliminated through the kidneys, so impaired renal function can cause the medication to accumulate.

✨ The nurse should monitor serum creatinine, BUN, urine output, and estimated renal function during therapy.

✨ Vancomycin dosing and intervals often require adjustment according to the client's renal function and drug exposure monitoring.

✨ The risk of kidney injury can increase when vancomycin is administered with other nephrotoxic medications.

✨ Therefore, vancomycin should be recognized as the medication with the clearest potential for nephrotoxicity among these choices.

Answer 7

Correct Answers:

"Reduce intake of foods high in potassium."

Rationale :

✳️ Clients with end-stage kidney disease (ESKD) have severely impaired ability to excrete potassium through the kidneys.

✳️ Potassium can consequently accumulate in the bloodstream and cause hyperkalemia.

✳️ Hyperkalemia is particularly dangerous because it can interfere with normal cardiac electrical conduction.

✳️ Severe elevations can produce muscle weakness, peaked T waves, widened QRS complexes, dysrhythmias, and cardiac arrest.

✳️ Clients with advanced kidney disease are therefore commonly instructed to limit high-potassium foods when serum potassium is elevated or restriction is prescribed.

✳️ Common high-potassium foods include bananas, oranges, tomatoes, potatoes, avocados, and dried fruits.

✳️ Dietary management before dialysis also commonly involves controlling sodium, phosphorus, fluid, and protein intake according to laboratory values and nutritional needs.

✳️ Therefore, reducing foods high in potassium is the appropriate instruction among the options provided.

Answer 8

Correct Answers:

The client has a 5 lb weight gain since yesterday.

Rationale :

💎 A rapid 5 lb (2.3 kg) weight gain in 24 hours strongly indicates significant fluid retention.

💎 Daily weight is one of the most reliable routine measurements for detecting changes in fluid volume.

💎 Approximately 1 kg (2.2 lb) of weight gain represents about 1 L of retained fluid.

💎 A 5 lb increase therefore represents roughly 2.3 L of additional fluid, assuming the change primarily reflects fluid accumulation.

💎 Clients with end-stage kidney disease (ESKD) cannot adequately eliminate excess sodium and water because of severely impaired renal function.

💎 Fluid accumulation between hemodialysis treatments can cause hypertension, peripheral edema, jugular venous distention, and pulmonary edema.

💎 Excessive fluid accumulation can eventually impair pulmonary gas exchange and cause dyspnea, crackles, and decreased oxygen saturation.

💎 Therefore, a 5 lb increase since the previous day is the clearest indication of fluid overload among these findings.

Answer 9

Correct Answers:

Hyperkalemia

Rationale :

⚽ Acute kidney injury (AKI) reduces the kidneys' ability to maintain normal fluid, electrolyte, and acid-base balance.

⚽ In prerenal AKI, decreased renal perfusion causes a reduction in glomerular filtration rate (GFR).

⚽ As filtration declines, the kidneys become less able to eliminate potassium effectively.

⚽ Potassium retention can consequently produce hyperkalemia, particularly as kidney dysfunction becomes more severe.

⚽ Hyperkalemia is a major concern because elevated potassium can disrupt cardiac electrical conduction.

⚽ Significant hyperkalemia can cause muscle weakness, peaked T waves, widened QRS complexes, dysrhythmias, and cardiac arrest.

⚽ The nurse should closely monitor serum potassium, renal function, urine output, and cardiac rhythm in clients with AKI.

⚽ Therefore, hyperkalemia is the expected electrolyte imbalance among the options provided.

Answer 10

Correct Answers:

PH 7.25, HCO3-19 mEq/L, PaCO2 30 mm Hg

Rationale :

🎯 Clients with chronic kidney disease (CKD) commonly develop metabolic acidosis because impaired kidneys cannot adequately excrete hydrogen ions.

🎯 Diseased kidneys also have a reduced ability to regenerate and conserve bicarbonate (HCO₃⁻).

🎯 A pH of 7.25 indicates acidemia because the normal arterial pH range is approximately 7.35–7.45.

🎯 An HCO₃⁻ of 19 mEq/L is decreased, identifying a metabolic cause of the acidosis.

🎯 The PaCO₂ of 30 mm Hg is decreased because the lungs compensate by increasing ventilation and eliminating more carbon dioxide.

🎯 This respiratory compensation helps raise the pH toward normal but does not completely correct the underlying metabolic acidosis.

🎯 Advanced CKD can also cause retention of phosphate, sulfate, and other acids, further contributing to metabolic acidosis.

🎯 Therefore, low pH + low HCO₃⁻ + compensatory low PaCO₂ is the expected ABG pattern.
