Nursing Elites

1. Which of the following is a common cause of acute kidney injury?

• A. Hypertension
• B. Dehydration
• C. Infection
• D. Hypotension

Correct answer: C

Rationale: Infection is a common cause of acute kidney injury because when the body fights an infection, it activates the immune response, leading to inflammation. This inflammatory response can affect the kidneys and impair their function. While hypertension (choice A) is a risk factor for chronic kidney disease, it is not a direct cause of acute kidney injury. Dehydration (choice B) can lead to prerenal acute kidney injury due to decreased blood flow to the kidneys, but infection is a more common cause of acute kidney injury. Hypotension (choice D) can contribute to prerenal acute kidney injury, but it is not a direct cause like infection.

2. A client with bladder cancer who underwent a complete cystectomy with ileal conduit is being assessed by a nurse. Which assessment finding should prompt the nurse to urgently contact the healthcare provider?

• A. The ileostomy is draining blood-tinged urine.
• B. There is serous sanguineous drainage on the surgical dressing.
• C. The ileostomy stoma appears pale and cyanotic.
• D. Oxygen saturations are 92% on room air.

Correct answer: C

Rationale: A pale or cyanotic appearance of the ileostomy stoma indicates compromised circulation, which can lead to necrosis if not promptly addressed. On the other hand, blood-tinged urine and serous sanguineous drainage are common following a complete cystectomy with ileal conduit. These findings do not typically indicate an urgent issue. An oxygen saturation of 92% on room air is slightly below the normal range but does not warrant urgent healthcare provider contact unless accompanied by significant respiratory distress or other concerning symptoms.

3. A patient who is taking trimethoprim-sulfamethoxazole (TMP-SMX) calls to report developing an all-over rash. What action should the nurse instruct the patient to perform?

• A. Increase fluid intake.
• B. Take diphenhydramine.
• C. Stop taking TMP-SMX immediately.
• D. Continue taking the medication.

Correct answer: C

Rationale: When a patient develops an all-over rash while taking trimethoprim-sulfamethoxazole (TMP-SMX), it may indicate a serious drug reaction. In this case, the patient should stop taking the medication immediately and notify their healthcare provider. Increasing fluid intake (Choice A) may be beneficial in some cases but is not the priority when a serious drug reaction is suspected. Taking diphenhydramine (Choice B) may help with itching but does not address the underlying issue of a potential drug reaction. Continuing the medication (Choice D) is not advisable when a serious adverse reaction such as a widespread rash occurs.

4. In a patient with chronic kidney disease, which of the following lab values would be expected?

• A. Elevated creatinine levels.
• B. Low hemoglobin levels.
• C. Elevated potassium levels.
• D. Low sodium levels.

Correct answer: A

Rationale: In chronic kidney disease, elevated creatinine levels are expected due to impaired kidney function. Creatinine is a waste product that is typically filtered out by the kidneys. With kidney disease, the clearance of creatinine is reduced, leading to its accumulation in the blood. Low hemoglobin levels (choice B) may be seen in chronic kidney disease due to decreased production of erythropoietin. However, elevated potassium levels (choice C) and low sodium levels (choice D) are more commonly associated with kidney dysfunction but are not as specific indicators of chronic kidney disease as elevated creatinine levels.

5. A healthcare professional is reviewing the results of serum laboratory studies of a client with suspected hepatitis. Which increased parameter is interpreted as the most specific indicator of this disease?

• A. Hemoglobin
• B. Serum bilirubin
• C. Blood urea nitrogen (BUN)
• D. Erythrocyte sedimentation rate (ESR)

Correct answer: B

Rationale: Serum bilirubin is the most specific indicator of hepatitis as it reflects liver dysfunction. Hemoglobin, blood urea nitrogen (BUN), and erythrocyte sedimentation rate (ESR) are not specific to hepatitis. Hemoglobin measures the oxygen-carrying capacity of red blood cells, BUN evaluates kidney function, and ESR is a nonspecific marker of inflammation or infection.
