If a patient's kidneys are failing to produce urine, which of the following physiological imbalances is most likely to occur?
- Decreased blood pressure due to fluid loss.
- Lowered concentration of waste materials in the blood.
- Increased levels of urea in the blood. (correct)
- Reduced water retention leading to dehydration.
A medication promotes increased water reabsorption in the kidneys. What is the most likely effect of this medication on blood pressure?
A medication promotes increased water reabsorption in the kidneys. What is the most likely effect of this medication on blood pressure?
- An increase in blood pressure due to increased blood volume. (correct)
- No change in blood pressure as kidneys only regulate waste.
- Unpredictable changes in blood pressure.
- A decrease in blood pressure due to reduced blood volume.

Study Notes
Kidney Function
- Kidneys primarily eliminate urea, excess water, and other waste materials from the body.
- Kidneys filter waste products from the blood.
- Kidneys produce urine as a means of waste removal.
- Kidneys play a role in regulating blood pressure.
Waste Elimination
- Kidneys remove urea, a nitrogenous waste product formed from the breakdown of proteins.
- Excess water is filtered out by the kidneys to maintain fluid balance in the body.
- Kidneys handle the elimination of various other waste materials, ensuring the body's internal environment remains stable.
Blood Filtration
- The primary role of the kidneys is to filter blood.
- By filtering blood, the kidneys remove waste products.
- The filtration process also allows the kidneys to reabsorb essential substances.
Urine Production
- Urine is the end product of kidney filtration and waste removal.
- The composition of urine reflects the waste products being eliminated from the body.
- Urine production is a continuous process, adjusting to the body's hydration levels and waste load.
Blood Pressure Regulation
- Kidneys contribute to blood pressure regulation through various mechanisms.
- The kidneys secrete hormones, such as renin, that affect blood pressure.
- Kidneys regulate blood volume by adjusting water reabsorption, which impacts blood pressure.
