Practice Question
When assessing a patient’s urine output, a nurse notes that the patient is producing less than 300 mL of urine in 24 hours. This condition is known as:
Answer Choices:
Correct Answer:
Oliguria
Rationale:
🟧 Oliguria is defined as urine output less than 400 mL in 24 hours, and values below 300 mL clearly meet this criterion.
🟧 This level of urine output can indicate renal impairment, dehydration, or decreased perfusion.
🟧 Oliguria requires prompt assessment of kidney function, fluids, medications, and hemodynamics.
🟧 Postoperative, critically ill, or dehydrated patients commonly exhibit oliguria—making recognition essential.
🟧 It is a clinical red flag that the kidneys may not be filtering or perfusing adequately, demanding timely intervention.
Anuria
🟧 Anuria is defined as less than 100 mL in 24 hours, which is far lower than the reported 300 mL.
🟧 The patient still has some urine production, so this is not cessation of output.
Polyuria
🟧 Polyuria refers to excessive urination, usually more than 2,000–3,000 mL/24 hrs.
🟧 The patient is producing too little, not too much.
Nocturia
🟧 Nocturia refers to nighttime urination, not low total daily output.
🟧 It is related to timing, not volume reduction.
