Which of the following are causes of intrarenal acute kidney injury? (Select all that apply.)
Hemoglobin from hemolyzed RBCs
Benign prostatic hyperplasia
Prostate cancer
Myoglobin release from necrotic muscle cells
Nephrotoxins
Correct Answer : A,D,E
Choice A rationale
Hemoglobin released from hemolyzed red blood cells (RBCs) can cause intrarenal acute kidney injury by obstructing the renal tubules and damaging the nephrons.
Choice B rationale
Benign prostatic hyperplasia is a cause of postrenal, not intrarenal, acute kidney injury as it can obstruct the flow of urine out of the bladder.
Choice C rationale
Prostate cancer, similar to benign prostatic hyperplasia, typically leads to postrenal acute kidney injury due to urinary obstruction.
Choice D rationale
Myoglobin released from necrotic muscle cells, as seen in conditions like rhabdomyolysis, can cause intrarenal acute kidney injury by precipitating in the renal tubules.
Choice E rationale
Nephrotoxins, such as certain medications, chemicals, or toxins, can directly damage the kidney tissue, leading to intrarenal acute kidney injury.

Correct Answer is A
Explanation
Choice A rationale
Diarrhea is a common symptom in both ulcerative colitis (UC) and Crohn's disease, often presenting with urgency and frequency.
Choice B rationale
Lesions that penetrate the intestine are more characteristic of Crohn's disease, which can affect any layer of the intestinal wall and any part of the gastrointestinal tract.
Choice C rationale
Strictures are more common in Crohn's disease due to its transmural inflammatory nature, which can lead to fibrosis and narrowing of the intestines¹.
Choice D rationale
UC is restricted to the colon and often involves the rectum, but Crohn's disease can affect any part of the gastrointestinal tract from the mouth to the anus and is not restricted to the rectum¹.
Correct Answer is A
Explanation
Choice A rationale
In the case of hyperkalemia, which can cause fatal cardiac arrhythmias, the most immediate nursing action is to place the patient on a cardiac monitor. This allows for continuous monitoring of the heart's rhythm and immediate detection of any life-threatening changes, which is crucial for timely intervention.
Choice B rationale
Inserting a urinary retention catheter may be necessary for managing oliguria, but it is not the most urgent action when compared to the potential cardiac risks associated with hyperkalemia.
Choice C rationale
Administering spironolactone, a potassium-sparing diuretic, could be part of the treatment for hyperkalemia, but it is not the first action to take. Spironolactone works more slowly and does not address the immediate risk of cardiac arrhythmias.
Choice D rationale
Epoetin alfa (Epogen) is used to treat anemia, particularly in chronic kidney disease, to increase red blood cell production. However, it does not have an immediate effect and is not the priority in the presence of hyperkalemia and potential cardiac complications.
