Final answer:
If the urine output is less than 1 to 2 mL/kg/hour, potassium chloride should not be administered.
Step-by-step explanation:
If the urine output is less than 1 to 2 mL/kg/hour, potassium chloride should not be administered. This is because a low urine output may indicate impaired kidney function or dehydration, and administering potassium chloride in such conditions can lead to electrolyte imbalances. It is important to monitor urine output and consult with a healthcare professional before administering any medication, including potassium chloride.
