    Correct Answer
    A. False
    Explanation
    Creatinine, phosphate, sulfates, and uric acid should be found in urine.

    Rate this question:

  • 3. 

    How do kidneys control Na+ levels and K+ levels?

    • The kidneys release renin, which controls angiotensin. The angiotensin controls aldosterone. Aldosterone controls the levels of Na+ and K+

    • Kidneys release aldosterone which controls renin. Renin causes the release of angiotensin. Angiotensin controls the levels of Na+ and K+

    • The kidneys release renin which controls K+. The kidneys release angiotensin which causes Na+ realease.

    Correct Answer
    A. The kidneys release renin, which controls angiotensin. The angiotensin controls aldosterone. Aldosterone controls the levels of Na+ and K+
    Explanation
    The correct answer explains the sequence of events in which the kidneys release renin, which then controls angiotensin. Angiotensin, in turn, controls aldosterone. Aldosterone is responsible for regulating the levels of Na+ and K+ in the body.

    Which of the following are abnormal to be found in the urine?

    • K

    • Amino acids

    • Glucose

    • All of the above

    • B and c

    Correct Answer
    A. B and c
    Explanation
    amino acids (proteins) found in the urine indicate trauma to the glomeruli. Glucose found in the urine indicate BS levels to be above the renal threshold.

    What is the # 1 renal function test?

    • Renal Clearance/Creatinine Clearance

    • Osmolarity

    • Serum Creatinine

    • BUN

    Correct Answer
    A. Renal Clearance/Creatinine Clearance
    Explanation
    Renal clearance/creatinine clearance is considered the #1 renal function test because it provides an accurate measure of the kidney's ability to remove waste and toxins from the blood. This test involves measuring the amount of creatinine, a waste product produced by the muscles, that is cleared from the blood by the kidneys in a given time period. A higher clearance rate indicates better kidney function, while a lower rate may suggest kidney dysfunction or disease. This test is commonly used to assess kidney function and monitor the progression of kidney diseases.

    What tests and results prove the presence of dilute urine?

    • Fixed Specific Gravity (1.010), and/or Fixed osmolality (300 mOsm/l)

    • GFR (100 ml/min), and/or Specific Gravity (1.030)

    • Serum Creatinine (1.5 mg/dl)

    Correct Answer
    A. Fixed Specific Gravity (1.010), and/or Fixed osmolality (300 mOsm/l)
    Explanation
    The presence of dilute urine can be confirmed by measuring the fixed specific gravity and/or fixed osmolality. A fixed specific gravity of 1.010 or lower indicates dilute urine, as does a fixed osmolality of 300 mOsm/l or lower. These measurements indicate that the urine has a low concentration of solutes, suggesting that the kidneys are not effectively concentrating the urine.

    Rate this question:

  • 7. 

    How many ml/hr of urine output is the normal minimum?

    Correct Answer
    Explanation
    The normal minimum urine output is typically around 30 ml/hr. This is considered to be the minimum amount needed to ensure proper kidney function and waste elimination. A lower urine output may indicate dehydration or kidney dysfunction. Monitoring urine output is important in assessing fluid balance and overall health status.

    Rate this question:

  • 8. 

    What could a decrease in BUN/Creatinine ratio indicate?

    Correct Answer
    fluid volume excess
    malnutrition
    fluid volume excess or malnutrition
    Explanation
    A decrease in BUN/Creatinine ratio can indicate fluid volume excess or malnutrition. This ratio is used to assess kidney function, and a decrease in the ratio suggests that the body is retaining more fluid than usual. Fluid volume excess occurs when there is an imbalance between fluid intake and output, leading to an accumulation of fluid in the body. Malnutrition, on the other hand, can lead to a decrease in protein intake, which can affect the production of urea (BUN) and creatinine. Therefore, a decrease in the BUN/Creatinine ratio can be indicative of both fluid volume excess and malnutrition.

  • 9. 

    What is the #1 cause of death when kidneys fail?

    Correct Answer
    hyperkalemia
    Explanation
    Hyperkalemia refers to a condition where there is an excessive amount of potassium in the blood. When kidneys fail, they are no longer able to effectively remove potassium from the body, leading to a buildup of potassium in the blood. This can result in serious complications, including cardiac arrhythmias and even death. Therefore, hyperkalemia is considered the number one cause of death when kidneys fail.

    Rate this question:

  • 10. 

    How acidic is urine compared to blood?

    • 100 times more acidic

    • 200 times less acidic

    • 1000 times more acidic

    • 2000 times more acidic

    Correct Answer
    A. 1000 times more acidic
    Explanation
    Urine is more acidic than blood, and specifically, it is approximately 1000 times more acidic. This is due to the presence of waste products and excess ions that are filtered out of the blood by the kidneys and excreted in the urine. The acidity of urine helps to maintain the body's pH balance and eliminate toxins.

    How much KCL do normal kidneys excrete each day?

    • 6-8 g

    • 1 g

    • 6-8 mg

    • 3 mg

    Correct Answer
    A. 6-8 g
    Explanation
    Normal kidneys excrete around 6-8 grams of potassium chloride (KCL) each day. KCL is an electrolyte that is important for maintaining proper fluid balance and nerve function in the body. The kidneys play a crucial role in filtering waste products, including KCL, from the blood and excreting them through urine. This daily excretion range of 6-8 grams ensures that the body maintains a healthy balance of KCL levels, preventing any potential imbalances or complications.

    What could an increase in BUN/Creatinine ratio indicate?

    Correct Answer
    Fluid Volume Deficit
    fluid volume deficit
    Explanation
    An increase in BUN/Creatinine ratio can indicate fluid volume deficit. This ratio is used to evaluate kidney function, and an elevated ratio suggests that there is a higher concentration of urea (BUN) relative to creatinine in the blood. In cases of fluid volume deficit, there is a decrease in blood volume, leading to reduced blood flow to the kidneys. This can result in increased reabsorption of urea and a higher BUN/Creatinine ratio.

    What is the most common early manifestation of kidney disease _____ and _____

    Correct Answer
    loss of concentration and dilute urine
    loss of ability to concentrate and dilute urine
    Explanation
    The most common early manifestation of kidney disease is the loss of concentration and dilute urine. This occurs when the kidneys are not functioning properly and are unable to concentrate the urine, leading to a higher volume of diluted urine. Additionally, the loss of ability to concentrate and dilute urine is also a common early sign of kidney disease, indicating impaired kidney function.

    What controls the amount of water reabsorbtion?

    Correct Answer
    Explanation
    The amount of water reabsorption is controlled by the kidneys. The kidneys are responsible for filtering waste products and excess water from the blood, and reabsorbing the necessary water back into the body. This process is regulated by hormones such as antidiuretic hormone (ADH) and aldosterone, which act on the kidney tubules to increase or decrease water reabsorption depending on the body's needs.
