On a typical day, medical personnel may encounter several situations involving measurement. State the name and type of measurement indicated by the units in each of the following:
a. The clotting time for a blood sample is 12 s.

Verified step by step guidance

1. Identify the unit provided in the problem. In this case, the unit is 's', which stands for seconds.
2. Determine what the unit 'seconds' measures. Seconds are a unit of time in the International System of Units (SI).
3. Understand the context of the problem. The clotting time refers to the duration it takes for a blood sample to clot, which is a time-based measurement.
4. State the name of the measurement. The name of the measurement is 'clotting time'.
5. Classify the type of measurement. Since the unit is seconds, the type of measurement is 'time'.

Key Concepts

Clotting Time

Clotting time refers to the duration it takes for blood to form a clot after a sample is taken. This measurement is crucial in assessing the blood's ability to coagulate, which is vital for diagnosing bleeding disorders or monitoring anticoagulant therapy.

Measurement Units

The unit 'seconds' (s) is a standard unit of time in the International System of Units (SI). In the context of clotting time, it quantifies the duration required for the clotting process to occur, providing a clear and objective measure for medical evaluation.

Types of Measurement

Measurements can be classified into various types, such as qualitative and quantitative. Clotting time is a quantitative measurement, as it provides a numerical value that can be used for comparison and analysis, essential for clinical decision-making.
