A nurse is preparing to begin a 24-hour urine collection for a client. Which of the following actions should the nurse take?
Discard the first voiding when beginning the test
Store collected urine in a designated container at room temperature
Document any urine collection that was missed during the 24 hours of the testing
Post a notice on the client's door regarding the test
The Correct Answer is A
Choice a reason: Discarding the first voiding when beginning a 24-hour urine collection is a crucial step in accurately measuring the components of urine over 24 hours. This step ensures that the test starts with an empty bladder and provides a precise beginning point. This action prevents the inclusion of residual urine from previous hours, which could affect the accuracy of the test results. The nurse collects all subsequent urine voids in a designated container throughout the test. By discarding the initial void, the measurement captures exactly 24 hours of urine production, crucial for diagnosing and monitoring various medical conditions.
Choice b reason: Storing collected urine at room temperature is incorrect. Urine collected for a 24-hour urine test must be stored in a cool environment, ideally refrigerated, to prevent bacterial growth and the breakdown of urine components. This ensures the urine sample remains stable and accurate for analysis. Storing at room temperature can compromise test accuracy and lead to false results.
Choice c reason: Documenting any missed urine collection is a good practice, but it doesn't directly impact the initial test process. The primary goal is to ensure all urine is collected accurately within the 24-hour window. Missed collections should be minimized to maintain the test's integrity. While documenting is important for transparency and understanding test discrepancies, it is not the immediate action the nurse should take when starting the test.
Choice d reason: Posting a notice on the client's door helps remind healthcare team members about the ongoing 24-hour urine collection. This prevents disruptions and ensures all urine output is collected accurately. However, this action, while important, supports the process rather than directly initiating the test. The nurse can post the notice to ensure everyone involved is aware, but it is not the first step in beginning the urine collection.

Correct Answer is A
Explanation
Choice a reason: Serum creatinine is a waste product formed by the normal breakdown of muscle tissue. It is filtered out of the blood by the kidneys and excreted in urine. Measuring the serum creatinine level provides critical information about kidney function. High levels of creatinine in the blood indicate impaired kidney function or kidney disease. Regular monitoring of serum creatinine is essential for patients with chronic kidney disease, those taking nephrotoxic medications, or in situations where acute kidney injury is suspected.
Choice b reason: Serum creatinine is not used to measure liver enzymes. Liver function is assessed through different tests, including measurements of enzymes such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST). These enzymes indicate liver health and function but are unrelated to serum creatinine levels.
Choice c reason: Evaluating thyroid function involves measuring specific thyroid hormones and thyroid-stimulating hormone (TSH), not serum creatinine. Thyroid function tests help diagnose and monitor conditions like hypothyroidism and hyperthyroidism, but they do not provide information about kidney function or serum creatinine levels.
Choice d reason: Monitoring blood glucose levels is crucial for managing diabetes, but it is unrelated to serum creatinine. Blood glucose levels are measured using specific tests like fasting blood glucose, HbA1c, and oral glucose tolerance tests. These tests help manage blood sugar but do not assess kidney function.
Correct Answer is D
Explanation
Choice a reason: A vegetarian diet is not a risk factor for bladder cancer. In fact, a diet high in fruits and vegetables may offer some protective effects against various cancers. There is no direct correlation between a vegetarian diet and an increased risk of bladder cancer.
Choice b reason: Alcohol use is not strongly linked to the development of bladder cancer. While excessive alcohol consumption can have various adverse health effects, it is not considered a primary risk factor for bladder cancer. Other factors play a more significant role in the etiology of this type of cancer.
Choice c reason: Caffeine use, such as drinking coffee or tea, has not been shown to significantly increase the risk of bladder cancer. Although studies have explored various dietary factors, caffeine consumption is not a known major risk factor for this disease.
Choice d reason: Tobacco use is a well-known risk factor for bladder cancer. Smoking is the most significant and established risk factor, as the carcinogens in tobacco are excreted in the urine, leading to prolonged exposure of the bladder lining to harmful substances. This increases the likelihood of developing bladder cancer. A history of tobacco use is commonly found in patients diagnosed with bladder cancer.
