Which statement is TRUE regarding urine output for a full-term infant weighing 3kg?

The statement that encompasses all the relevant factors regarding urine output in a full-term infant weighing 3 kg is accurate. Urine output in newborns is influenced by several physiological factors, including circulation and perfusion.

Firstly, urine output is related to circulation because effective blood flow is necessary for the kidneys to filter blood and produce urine. A well-functioning circulatory system ensures that adequate blood reaches the kidneys, facilitating their function.

Secondly, urine output is closely related to perfusion. Perfusion refers to the flow of blood through the body's tissues, which is crucial for renal function. Adequate renal perfusion is essential for maintaining normal urine output, as the kidneys need a sufficient blood supply to filter waste and produce urine effectively.

Finally, regarding the normal urine output for a full-term infant, it is generally expected to be around 1 to 2 mL/kg/hour, which translates to a normal output for a 3 kg infant being approximately 3 to 6 mL/hour. Therefore, stating that the normal value is 3 mL/hour could be misleading without the context of a range. However, when considering all the elements together, it is evident that the statement that all of these aspects are true encompasses the complexity of urine output
