1. What is the most important nursing intervention for a patient with increased intracranial pressure (ICP)?
- A. Elevate the head of the bed to 30 degrees.
- B. Administer diuretics to reduce fluid volume.
- C. Administer corticosteroids to reduce inflammation.
- D. Keep the patient in a supine position.
Correct answer: A
Rationale: Elevating the head of the bed to 30 degrees is crucial for a patient with increased intracranial pressure (ICP) because it helps promote venous drainage from the brain, thereby reducing ICP. Keeping the head of the bed elevated helps facilitate cerebral perfusion and can prevent a further increase in ICP. Administering diuretics (Choice B) may be considered in some cases to reduce fluid volume, but it is not the most critical intervention for immediate ICP management. Administering corticosteroids (Choice C) is not typically indicated for managing increased ICP unless there is a specific underlying condition requiring their use. Keeping the patient in a supine position (Choice D) can actually worsen ICP by impeding venous outflow from the brain, making it an incorrect choice for this scenario.
2. The nurse is caring for a client with chronic renal failure who is receiving peritoneal dialysis. Which of the following findings should be reported immediately to the physician?
- A. Clear dialysate outflow.
- B. Increased blood pressure.
- C. Cloudy dialysate outflow.
- D. Decreased urine output.
Correct answer: C
Rationale: Cloudy dialysate outflow should be reported immediately to the physician. It is indicative of peritonitis, a severe infection of the peritoneal cavity and a serious complication of peritoneal dialysis. Prompt medical attention is crucial to prevent further complications or systemic infection. Clear dialysate outflow (Choice A) is a normal finding in peritoneal dialysis. Increased blood pressure (Choice B) and decreased urine output (Choice D) are common in clients with chronic renal failure and may not require immediate reporting unless they are significantly abnormal or accompanied by other concerning symptoms.
3. A patient is being treated for shock after a motor vehicle accident. The provider orders 6% dextran 75 to be given intravenously. The nurse should expect which outcome as the result of this infusion?
- A. Decreased urine output
- B. Improved blood oxygenation
- C. Increased interstitial fluid
- D. Stabilization of heart rate and blood pressure
Correct answer: D
Rationale: 6% Dextran 75 is a high molecular-weight colloidal solution used to treat shock from burns or trauma. Colloids like 6% dextran 75 are plasma expanders that help increase blood volume, leading to improved heart rate and blood pressure stabilization. The infusion of plasma expanders does not typically decrease urine output. It primarily aims to stabilize circulation rather than affect blood oxygenation or increase interstitial fluid levels.
4. The provider has ordered Kayexalate and sorbitol to be administered to a patient. The nurse caring for this patient would expect which serum electrolyte values prior to administration of this therapy?
- A. Sodium 125 mEq/L and potassium 2.5 mEq/L
- B. Sodium 150 mEq/L and potassium 3.6 mEq/L
- C. Sodium 135 mEq/L and potassium 6.9 mEq/L
- D. Sodium 148 mEq/L and potassium 5.5 mEq/L
Correct answer: C
Rationale: Severe hyperkalemia, with a potassium level of 6.9 mEq/L, requires aggressive treatment with Kayexalate and sorbitol to increase the body’s excretion of potassium. The normal range for serum potassium is 3.5 to 5.5 mEq/L, so patients with the other potassium levels would not be treated aggressively or would need potassium supplementation. Therefore, option C (Sodium 135 mEq/L and potassium 6.9 mEq/L) is the correct choice as it indicates severe hyperkalemia warranting the administration of Kayexalate and sorbitol. Options A, B, and D have either potassium levels within normal limits, which would not necessitate this aggressive treatment, or potassium levels that are lower than what would typically prompt the need for Kayexalate and sorbitol.
5. The nurse is caring for five clients on the medical-surgical unit. Which clients would the nurse consider to be at risk for post-renal acute kidney injury (AKI)? (Select all that apply.)
- A. Man with prostate cancer
- B. Woman with blood clots in the urinary tract
- C. Client with ureterolithiasis
- D. All of the above
Correct answer: D
Rationale: Post-renal acute kidney injury (AKI) occurs due to urine flow obstruction, which can result from conditions such as prostate cancer, blood clots in the urinary tract, and ureterolithiasis (kidney stones). Severe burns would lead to pre-renal AKI by reducing blood flow to the kidneys. Lupus would cause intrarenal AKI by affecting the kidney tissue directly. Therefore, options A, B, and C are correct choices for clients at risk for post-renal AKI, making option D the correct answer.
