Which pathophysiologic events contribute to renal failure associated with tumor lysis syndrome?
Metabolic acidosis.
Elevated white blood cell count.
Crystallization of uric acid in the renal tubules.
Hypocalcemia.
The Correct Answer is C
Choice A rationale
Metabolic acidosis can occur in renal failure but is not directly linked to tumor lysis syndrome.
Choice B rationale
Elevated white blood cell count is not a primary contributor to renal failure in tumor lysis syndrome.
Choice C rationale
Crystallization of uric acid in the renal tubules can obstruct urine flow and cause acute renal failure, which is a direct pathophysiologic event in tumor lysis syndrome.
Choice D rationale
Hypocalcemia is a consequence of tumor lysis syndrome but does not directly cause renal failure.

Correct Answer is ["A","C"]
Explanation
Choice A rationale:
Tachycardia: Heatstroke often leads to an elevated heart rate due to the body's attempt to cool down and compensate for increased body temperature. The heart rate of 120 beats per minute noted in the client is consistent with tachycardia.
Choice B rationale:
Hallucinations: While confusion and disorientation are common symptoms of heatstroke, hallucinations are not typical findings associated with heatstroke. Therefore, this is not a consistent finding for this diagnosis.
Choice C rationale:
Skin is hot, dry: One of the hallmark signs of heatstroke is hot, dry skin, which results from the body's inability to regulate its temperature effectively. The client's skin being hot to the touch and dry aligns with this characteristic.
Choice D rationale:
Bradycardia: This is characterized by a slower than normal heart rate. Since the client presents with a heart rate of 120 beats per minute, which indicates tachycardia, bradycardia is not a finding consistent with heatstroke.
Correct Answer is D
Explanation
Choice A rationale
Metoclopramide does not work by decreasing gastric acid secretions. It is not classified as an antacid or acid suppressant.
Choice B rationale
Metoclopramide does not relieve nausea by slowing peristalsis. In fact, it increases peristalsis, which helps move contents through the gastrointestinal tract more quickly.
Choice C rationale
Metoclopramide does not work by relaxing gastric muscles. Instead, it enhances the tone and motility of the gastrointestinal tract.
Choice D rationale
Metoclopramide relieves nausea by promoting gastric emptying. It increases the movement of the stomach and intestines, which helps reduce feelings of nausea and vomiting.
