The Importance of Urine Output Calculation in Pediatric Nursing Care

Understanding Urine Output Calculation in Pediatric Patients

Caring for pediatric patients requires accurate monitoring of various parameters, including urine output. One common method used by healthcare professionals is to calculate the urine output in mL/kg/hr. This calculation helps determine the renal function and hydration status of the patient, especially in situations where fluid balance is critical.

Let's consider a scenario where a nurse is caring for a 6-year-old patient weighing 220.5kg. The patient's order states, "N5 bolus 10mL/kg once every 4 hours as needed for UOP less than 1mL/kg/hr." The patient has had 2 urine occurrences from 0700-1100, measuring 30mL and 45mL. Now, the question arises: What is the child's calculated urine output (mL/kg/hr)?

Calculating the Child's Urine Output

The patient had a total urine output of 75mL from 0700-1100, over a 4-hour period. To calculate the urine output in mL/kg/hr, we divide the total urine volume (75mL) by the number of hours (4 hours) and then by the patient's weight (220.5kg).

Calculation:

(75 mL / 4 hours) / 220.5 kg = 0.09 mL/kg/hr

When rounded to the nearest tenth, the child's calculated urine output is 0.1 mL/kg/hr. It seems there might be a mistake in the question or the choices provided, as none of the options match the calculated value.

It is essential for healthcare professionals to understand and accurately calculate urine output in pediatric patients to assess their renal function and hydration status effectively.

Conclusion

Urine output calculation plays a crucial role in pediatric nursing care. By accurately monitoring and calculating urine output in mL/kg/hr, healthcare professionals can assess the renal function and hydration status of pediatric patients efficiently. This information is vital in managing fluid balance and ensuring optimal patient care.
