A patient's urine output is lower than expected. Which nursing response best follows the monitoring principles?

  1. A

    Treat low urine output by itself as a definitive diagnosis of fluid deficit.

  2. B

    Reassess the patient and report the finding as indicated, considering the overall condition.

  3. C

    Ignore the finding unless the patient also has edema.

  4. D

    Assume it proves that circulating volume is adequate.

How should a nurse obtain weight measurements to make fluid-status trends more reliable?

  1. A

    Use any available scale and weigh at varying times to capture more data.

  2. B

    Use the same scale, similar clothing, and a consistent time of day.

  3. C

    Weigh only when the patient reports thirst.

  4. D

    Compare a single measurement with a population average instead of the patient's trend.

A patient has peripheral edema. Which interpretation is most accurate?

  1. A

    Edema proves that circulating volume is adequate.

  2. B

    Edema may coexist with inadequate circulating volume because fluid can be poorly distributed between compartments.

  3. C

    Edema by itself confirms pulmonary congestion.

  4. D

    Edema rules out the need to assess other fluid-status findings.

Which statement best describes the approximate relationship between a rapid weight change and body water?

  1. A

    A change of about one kilogram corresponds approximately to a change of one liter of water.

  2. B

    A change of about one kilogram corresponds approximately to a change of ten liters of water.

  3. C

    A change of about one liter of water has no relationship to body weight.

  4. D

    A kilogram of weight change proves that the change is entirely body water.

A nurse is reviewing a patient's fluid intake for the shift. Which approach best supports an accurate intake record?

  1. A

    Count only drinks and foods because prescribed treatments are not intake.

  2. B

    Include prescribed IV fluids and account for fluid in medications and blood products when relevant.

  3. C

    Record medications and blood products as output unless they are given orally.

  4. D

    Exclude enteral feeds because they are not taken by mouth.

A patient's urine output is lower than expected. What is the most appropriate nursing response?

  1. A

    Diagnose fluid deficit based on urine output alone.

  2. B

    Ignore the finding if the patient has no edema.

  3. C

    Reassess the patient and report the finding as indicated, interpreting it with the overall condition.

  4. D

    Wait until the next scheduled weight before assessing the patient.

Which description best explains how the body helps regulate water and electrolyte balance?

  1. A

    The kidneys adjust water and electrolyte excretion, with thirst and hormonal responses supporting regulation.

  2. B

    The lungs directly determine sodium balance and control kidney excretion.

  3. C

    The kidneys regulate fluid balance only by changing the amount of interstitial fluid.

  4. D

    Thirst alone controls water retention, without a role for the kidneys or hormones.
