Correct Answer: A. 8

One cup is equal to 8 ounces. Weight conversion is also utilized daily in health care. There are two systems calculating weight used in all healthcare settings for health management, such as medication dosing per patient body weight. First, the metric system is in common use in health care in the US. It is also the only system universally used in many countries on all continents of the globe. It has the advantage of a decimal system in increments or the power of tenths. Second, the US weight system customarily uses the ounce or pound. It derives from the British colonial era. This non-metric system is still being used nowadays among laypersons in the US for products sold to the public.

Option B: The metric system is essential in all health care settings. Patients are weighed at each clinical encounter. Scales used in the US have double marking indicators: metric and non-metric markings. Metric weight values are used in medication calculation, radiation dosing, and weight compliance in equipment use, such as the maximum weight of a CAT-SCAN unit or a surgical table that may hold a person.
Option C: Nowadays, all medications are based on weight for dose calculations for all populations but very specifically in children and infants. Adults have their weight recorded mainly by their doctors at each physical patient-clinician encounter. Commonly, most adults monitor their weight for weight management. Clinicians record it in the electronic health records in both kilograms and pounds.
Option D: Commonly in healthcare and medical practices, the metric system is used for weighing mass. In the metric system, there are increments at the power of the tenth for calculations. This weight conversion is used daily among scientists and health care providers.
