Correct Answer is A

Explanation

A. The tablets in the new refill contain the same amount of medication: 0.75 mg is equivalent to 750 mcg (1 mg = 1000 mcg), so the dose strength has not changed. The patient is receiving the same amount of active drug.

B. The tablets in the refill bottle contain less medication: Converting 0.75 mg to micrograms shows it equals 750 mcg, so the refill does not contain less medication.

C. The tablets in the refill bottle have a greater dose of medication: The dose is identical, not greater. There is no change in the amount of active ingredient per tablet.

D. The pharmacy needs to provide tablets that contain 750 mcg of medication: Although the labeling changed, 0.75 mg is equivalent to 750 mcg. The refill is correct and safe to use.

A. 750 mg: 1 tablet :: 1,500 mg: x tablet B. Which of the following represents the correct multiplication of the means and extremes? C. 750 x 1,500 = 1 xX D. 1 x 1,500 = 750 × X E. 1 x x = 750 × 1,500

Correct Answer is C

Explanation

A. 750 x 1,500 = 1 x X: This incorrectly multiplies the known dose by the desired dose without following the proper proportion rule of means and extremes.

B. 1 x 1,500 = 750 × X: This setup places the number of tablets on the wrong side of the equation, making the calculation incorrect.

C. 1 x x = 750 × 1,500: This correctly applies the rule of means and extremes, multiplying the means (1 and 1,500) and extremes (750 and x) to solve for the unknown number of tablets.

D. 750 x 1 = 1,500 x x: This reverses the proportion setup and does not accurately solve for x, leading to an incorrect calculation
