1 Teaspoon (t, tsp) equals how many mL?
A. 5 mL B. 10 mL C. 15 mL D. 20 mL
The Correct Answer and Explanation is:
The correct answer is A. 5 mL.
Explanation:
The measurement of teaspoons (tsp) and milliliters (mL) is common in the medical and culinary fields, particularly when measuring liquid medications or ingredients. Understanding the conversion between these two units is essential, especially in nursing practice, where precise medication dosing is critical.
1 teaspoon (tsp) is generally equal to 5 milliliters (mL). This is based on the standard metric conversion system commonly used in health care, cooking, and science. The teaspoon is a unit of volume used in both the U.S. customary system and the metric system, and the milliliter is a metric unit of volume. Although a teaspoon can sometimes be informally referred to as a “tsp,” in medical settings, it is important to ensure accuracy when administering medications or measuring liquids.
Conversion:
- 1 teaspoon (tsp) = 5 milliliters (mL)
This relationship can be helpful in various nursing and medical contexts. For example, when a healthcare provider prescribes a medication to be taken in teaspoons, it is crucial to convert this volume into milliliters, especially when the medication is dispensed with a syringe or measuring cup marked in milliliters.
Example Calculation:
If a doctor orders a patient to take 2 teaspoons of liquid medicine, we would convert it to milliliters as follows:
- 2 teaspoons × 5 mL per teaspoon = 10 mL.
Knowing this conversion helps ensure that the patient receives the correct amount of medication, promoting accurate dosing and improving patient safety.
While other options like 10 mL, 15 mL, or 20 mL might seem reasonable, they are incorrect for this specific conversion. Thus, the standard metric conversion of 1 teaspoon = 5 milliliters is vital to remember when working with medications or liquids.
