Final answer:
The patient's blood pressure medication dosage was decreased by 1.55 grams, moving from an initial 2 grams to 0.45 grams. The correct answer is b) 1.55 grams.
Explanation:
A dose is a measured quantity of a medicine, nutrient, or pathogen which is delivered as a unit. The greater the quantity delivered, the larger the dose. Doses are most commonly measured for compounds in medicine. The term is usually applied to the quantity of a drug or other agent administered for therapeutic purposes, but may be used to describe any case where a substance is introduced to the body.
In nutrition, the term is usually applied to how much of a specific nutrient is in a person's diet or in a particular food, meal, or dietary supplement. The patient's dosage was originally 2 grams and was decreased to 0.45 grams. To find out by how much the dosage was decreased, you subtract the new dosage from the original dosage. 2 grams (original dosage) - 0.45 grams (new dosage) = 1.55 grams (amount decreased). Therefore, the dosage was decreased by 1.55 grams, which corresponds to option b).
