The Nurse’s Role in Urinary Elimination
The 14 things this section of the textbook says that you are most likely to be asked about — quoted word for word, not retold. Then 4 practice questions with the reasoning.
Key points
Urinalysis clinical value
This routine medical test provides valuable information about kidney function, hydration status, and the presence of underlying health conditions.
Normal urine appearance
Normal urine should be clear, pale to light yellow in color, and not foul smelling.
Urine color changes
Alterations in urine color, such as darkening or unusual hues, can signal issues like dehydration, hematuria (visible or microscopic blood in urine), or liver dysfunction.
Clarity and odor cues
Clarity of urine aids in identifying conditions like UTIs, while an abnormal odor may suggest infections or metabolic disorders.
Urine volume monitoring
Monitoring urine volume is essential for assessing hydration status and potential issues with fluid balance.
Minimum daily urine output
The kidneys must produce a minimum urine volume of about 500 mL/day to rid the body of wastes.
Urinary retention risk
In addition to causing discomfort, urinary retention increases the patient’s risk for developing a UTI.
Urinary retention presentation
Clinically, urinary retention can present with symptoms such as a distended bladder, lower abdominal discomfort, and the inability to initiate or sustain a urine stream.
Retention physical assessment
Physical examination techniques, such as palpation of the lower abdomen for a palpable and distended bladder, and percussion to assess for dullness, can aid in diagnosing urinary retention.
Postvoid residual measurement
Additionally, ultrasound, bladder scans, or straight catheterization may be employed to determine postvoid residual urine volume, a measurement of urine left in the bladder after a patient has voided.
PVR normal range
The identification of urinary retention is crucial as it can result from various causes, including structural issues, neurological disorders, or medications. Normal PVR volume is typically between 50 and 100 mL.
Residual urine management
The results of residual urine measurements guide healthcare professionals in developing appropriate treatment plans and interventions to address the underlying causes of impaired urinary elimination.
Incontinence patient education
Nurses can greatly improve the quality of life for these patients by assessing for incontinence in a sensitive manner and then providing patient education about methods to prevent or manage symptoms.
Incontinence assessment factors
It is also essential to assess fluid intake, voiding patterns, and the presence of other contributing factors, such as neurological conditions or medications.
Terms to know
- urinalysis
- A diagnostic examination of a urine sample to assess various aspects of a person’s health is called urinalysis.
- urinary retention
- Urinary retention refers to the inability to empty the bladder completely, leading to the accumulation of urine.
- oliguria
- Output below this level may be caused by severe dehydration or kidney disease and is termed oliguria.
- anuria
- The virtual absence of urine production is termed anuria, which may be due to conditions such as kidney failure or shock.
- polyuria
- Excessive urine production is polyuria, which may be due to diabetes mellitus or diabetes insipidus.
- postvoid residual urine volume
- Additionally, ultrasound, bladder scans, or straight catheterization may be employed to determine postvoid residual urine volume, a measurement of urine left in the bladder after a patient has voided.
- Urinary incontinence
- Urinary incontinence is the involuntary loss of urine.

Every question here, with the answer
A postoperative patient reports lower abdominal discomfort and has been unable to void. Which nursing action best evaluates whether urine is being retained in the bladder?
- Use a bladder scanner to measure the amount of urine present.
- Ask the patient whether the urine has a foul odor.
- Document the finding as expected and reassess at the end of the shift.
- Send a urine specimen only to evaluate pH.
Answer: Use a bladder scanner to measure the amount of urine present.
A bladder scan is a noninvasive way to assess urine volume in the bladder and helps identify urinary retention. Urine pH or odor may provide other information but does not measure retained urine, and delaying assessment could miss retention and its complications.
A nurse is assessing a patient for possible urinary retention. Which assessment findings or actions are appropriate? Select all that apply.
- Ask whether the patient strains during voiding.
- Inspect the patient’s urine only for pale yellow color.
- Percuss the lower abdomen to assess for dullness.
- Palpate the lower abdomen for a distended bladder.
- Ask about the frequency and volume of urination.
Answer: Ask whether the patient strains during voiding., Percuss the lower abdomen to assess for dullness., Palpate the lower abdomen for a distended bladder., Ask about the frequency and volume of urination.
Assessment for urinary retention includes questions about voiding patterns, straining, and discomfort, as well as physical assessment for a distended bladder. Urine color can be useful in urinalysis but does not directly assess bladder retention.
A nurse reviews a patient’s intake and output record and notes a urine output of 400 mL in 24 hours. How should the nurse interpret this finding?
- Oliguria
- Anuria
- Polyuria
- Normal urine output
Answer: Oliguria
A 24-hour urine output of 400 mL falls within the oliguria range. It is not normal output, not polyuria, and not anuria because anuria is a much lower volume.
A patient tells the nurse, “I leak urine when I laugh or cough, but I’m embarrassed to talk about it. Maybe it is just part of aging.” Which nursing response is most appropriate?
- “Thank you for telling me. Let’s discuss when it started and what triggers it so we can look at ways to manage it.”
- “You should avoid social activities until the leaking stops.”
- “You are right; this is a normal part of aging and usually does not need discussion.”
- “There is no need to assess this unless you also have pain with urination.”
Answer: “Thank you for telling me. Let’s discuss when it started and what triggers it so we can look at ways to manage it.”
The nurse should address urinary incontinence sensitively, assess patterns and triggers, and provide education about prevention or management. The section notes that some patients mistakenly believe incontinence is a normal part of aging, and embarrassment can lead to isolation.
