Acute Renal Failure Questions and Answers 2024

Acute Renal Failure Questions and Answers 2024 The nurse is admitting a client diagnosed with acute renal failure (ARF). Which ques- tion would be most important for the nurse to ask during the admission interview? 1. "Have you recently traveled outside the United States?" 2. "Did you recently begin a vigorous exercise program?" 3. "Is there a chance you have been exposed to a virus?" 4. "What over-the-counter medications do you take regularly?" - answer 1. Usually there are no diseases or conditions that would warrant this question when discussing ARF. 2. Vigorous exercise will not impede blood flow to the kidneys, leading to ARF. 3. Usually viruses do not cause ARF. ***4. Medications such as nonsteroidal anti- inflammatory drugs (NSAIDs) and some herbal remedies are nephrotoxic; therefore, asking about medications is appropriate. TEST-TAKING HINT: Asking about medications, especially over-the-counter and herbal remedies, during the admission interview is an important intervention because many of these are nephrotoxic and hepatotoxic. The client is diagnosed with ARF. Which laboratory values are most significant for diagnosing ARF? 1. BUN and creatinine. 2. WBC and hemoglobin. 3. Potassium and sodium. 4. Bilirubin and ammonia level. - answer ***1. Blood urea nitrogen (BUN) levels reflect the balance between the production and excretion of urea from the kidneys. Creati- nine is a byproduct of the metabolism of the muscles and is excreted by the kidneys. Creatinine is the ideal substance for deter- mining renal clearance because it is rela- tively constant in the body and is the laboratory value most significant in diag- nosing renal failure. 2. WBCs (white blood cells) are monitored for infection, and hemoglobin is monitored for blood loss. 3. Potassium (intracellular) and sodium (intersti- tial) are electrolytes and are monitored for a variety of diseases or conditions not specific to renal function. Potassium levels will increase with renal failure, but the level is not a diag- nostic indicator for renal failure.
