Mr. T. W. is admited to your unit with a diagnosis of small bowel obstruction after swallowing a golf ball related to a freak golfing accident. Mr. T. W.'s urine output has been steadily decreasing, and pre-renal failure is suspected. Which of the following conditions would likely cause pre-renal failure?
Nephrotoxicity
Acute tubular necrosis
Hypovolemia
Acute Glomerulonephritis
The Correct Answer is C
Choice A reason: Nephrotoxicity causes intrinsic renal failure due to direct damage to the renal parenchyma, not pre-renal failure.
Choice B reason: Acute tubular necrosis is a type of intrinsic renal failure resulting from damage to the renal tubules, not pre-renal failure.
Choice C reason: Hypovolemia is a common cause of pre-renal failure due to decreased blood flow to the kidneys, leading to reduced urine output.
Choice D reason: Acute Glomerulonephritis is an intrinsic renal condition that affects the glomeruli, not a pre-renal cause.

Correct Answer is B
Explanation
Choice A reason: Dabigatran does not specifically slow the ventricular response; medications like beta-blockers are typically used for rate control in atrial fibrillation.
Choice B reason: Dabigatran is an anticoagulant that reduces the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation by preventing clot formation.
Choice C reason: Dabigatran does not convert atrial fibrillation to sinus rhythm; that would be the role of antiarrhythmic drugs or procedures like cardioversion.
Choice D reason: While dabigatran can prevent clots from forming, it is not used to dissolve existing clots; thrombolytic agents are used for that purpose.
Correct Answer is A
Explanation
Choice A reason: Evaluating the effectiveness of opioid analgesics is crucial as pain management is a primary concern for patients experiencing a sickle cell crisis.
Choice B reason: Limiting the patient's intake of oral and IV fluids is not recommended as hydration is important for patients with sickle cell crisis to reduce blood viscosity and improve circulation.
Choice C reason: Teaching the patient about high-protein, high-calorie foods is beneficial for long-term management but is not the immediate nursing intervention during a crisis.
Choice D reason: Encouraging ambulation may be part of recovery but is not the primary intervention during an acute sickle cell crisis due to the risk of pain exacerbation.
