Extract:
Question 1 of 5
The nurse is caring for a client who has chronic renal disease and is receiving therapy with erythropoietin (epoetin alpha). Which of the following laboratory results should the nurse review as an indication of a therapeutic effect of this medication?
Correct Answer: B
Rationale: Erythropoietin stimulates red blood cell production, increasing hemoglobin levels in clients with CKD-related anemia.
Question 2 of 5
What type of electrolyte imbalance would most likely occur following the administration of three tap water enemas?
Correct Answer: A
Rationale: Tap water enemas can cause potassium loss via stool and dilutional effects, leading to hypokalemia.
Question 3 of 5
The client receiving hemodialysis is complaining of being dizzy and light-headed. Which action should the nurse implement first?
Correct Answer: A
Rationale: Dizziness and lightheadedness during dialysis suggest hypotension, a common complication. The nurse should first assess vital signs to determine the severity before taking further action.
Question 4 of 5
The client has just returned from OR with respirations of 8 per minute. What set of ABG's would the nurse expect to see?
Correct Answer: B
Rationale: Hypoventilation (8 breaths/min) causes COâ‚‚ retention, leading to respiratory acidosis (low pH, high PaCO2).
Question 5 of 5
The nurse is caring for a client diagnosed with acute renal failure and has a potassium level of 8.3 mEq/L. What collaborative intervention would be a priority for this client?
Correct Answer: A
Rationale: A potassium level of 8.3 mEq/L is critically high, putting the client at immediate risk for life-threatening cardiac arrhythmias. Emergency dialysis is needed to remove excess potassium.
