A nurse is reviewing a patient's records and notes that the patient has renal disorder. The nurse expects to note which of the following laboratory results:?

Option 3 : Elevated serum creatinine level

Concept

• Patient record -> The information relevant for continuity of a patient's treatment if stored in the patient record.
• Renal disorder -> A disease condition where the kidneys are unable to function normally.
• Various diagnostic tests can be done to confirm the presence of renal disorders.

Explanation:

• The kidneys usually filter out waste material such as creatinine molecules from the body through urine.
• In case of a renal disorder, improper filtration through the kidneys would result in higher levels of creatinine in the blood.
• Elevated serum creatinine level is one of the laboratory tests done to diagnose renal disorders.

• Decreased serum potassium level -> Improper heart functioning could be indicated through lowered serum potassium levels.
• Decreased serum phosphate level -> Hyperparathyroidism is indicated through decreased serum levels of phosphate.
• Increased hemoglobin level -> Polycythemia usually leads to an increased level of hemoglobin, which is often caused due to low availability of oxygen.
