A nurse is assisting an assistive personnel to document a client's weight in the medical record. Which of the following should the nurse identity as a metric unit?

A) Pound: The pound (lb) is a unit of weight in the imperial system, not the metric system. While pounds are commonly used in the United States for body weight, they are not considered a metric unit of measurement. In the metric system, kilograms are used to measure weight, and pounds are typically converted to kilograms when using international standards. B) Minim: A minim is a very small unit of volume in the apothecaries' system, which is an older system of measurement. The minim is not used in the modern metric system. It is not applicable for weight measurement and would not be considered a metric unit. C) Kilogram: The kilogram (kg) is the standard unit of weight in the metric system. It is the most commonly used metric unit for measuring body weight in healthcare settings. Kilograms are used internationally and are part of the International System of Units (SI). Therefore, this is the correct answer. D) Ounce: An ounce (oz) is a unit of weight in the imperial system, similar to pounds. It is commonly used in the United States but is not part of the metric system. The metric equivalent of ounces is grams, and weight is typically measured in grams or kilograms in the metric system.
