Multiple Choice

A nurse is caring for a client who has a diagnosis of renal calculi. Which of the following is the primary function of the kidneys that may be affected by this condition?

Filtration of blood to form urine

Production of digestive enzymes

Synthesis of red blood cells in the bone marrow

Regulation of blood glucose levels

Verified step by step guidance

Understand the primary function of the kidneys: The kidneys are responsible for filtering blood to remove waste products, excess substances, and toxins, which are then excreted as urine. This is a critical function for maintaining homeostasis in the body.

Identify the condition mentioned: Renal calculi, commonly known as kidney stones, are solid masses formed from crystals in the kidneys. These stones can obstruct the flow of urine and impair the kidney's ability to filter blood effectively.

Evaluate the options provided: Analyze each option to determine which one aligns with the primary function of the kidneys. For example, 'Filtration of blood to form urine' directly relates to the kidney's role, while the other options pertain to functions of other organs or systems.

Eliminate incorrect options: 'Production of digestive enzymes' is a function of the pancreas, not the kidneys. 'Synthesis of red blood cells in the bone marrow' is regulated by erythropoietin, a hormone produced by the kidneys, but the synthesis itself occurs in the bone marrow. 'Regulation of blood glucose levels' is primarily managed by the liver and pancreas.

Select the correct answer: Based on the analysis, the primary function of the kidneys affected by renal calculi is 'Filtration of blood to form urine.' This is the most relevant option given the condition described.
