One ounce is equivalent to_________cc’s (or mL’s) A. 15 cc (mL) B. 30 cc (mL) C. 100 cc (mL) D. 240 cc (mL)
The Correct Answer and Explanation is :
One ounce is equivalent to 30 cc (mL), so the correct answer is B.
Explanation:
The conversion between ounces and cubic centimeters (cc) or milliliters (mL) is based on the metric system, which is commonly used in healthcare and scientific fields. An ounce is a unit of volume in the customary system, while cubic centimeters and milliliters are units in the metric system. Understanding these conversions is essential, particularly in nursing and healthcare settings where precise dosages of medications are crucial.
- Metric vs. Customary Units: In the customary system, the fluid ounce (fl oz) is often used for liquid measurements. There are two primary types of ounces: the US fluid ounce and the UK fluid ounce. However, in most medical contexts, the US fluid ounce is used, where 1 US fluid ounce is approximately equal to 29.57 mL. For simplicity in healthcare, this is often rounded to 30 mL or 30 cc.
- Conversions: The relationship between ounces and milliliters can be particularly important when administering medication. For example, if a prescription calls for a dosage in milliliters but the medication is in an ounce bottle, knowing that 1 ounce equals about 30 mL allows healthcare providers to calculate the correct dosage quickly.
- Clinical Implications: Accurate conversions are vital to avoid medication errors. A miscalculation could lead to underdosing or overdosing a patient, which can have serious consequences. For instance, pediatric dosing often requires precise measurement due to the varying weights and sizes of children, making the understanding of these conversions all the more critical.
In summary, knowing that one ounce is equivalent to 30 cc (mL) facilitates proper medication administration and enhances patient safety in healthcare settings.
