Rx: Codeine phosphate 30 mg/tsp Tussin syrup 30mL Elixophyllin qs 240 mL Sig: 5mL qid pc hs If 5 mL of Tussin syrup contains 100
kotykmax [81]

Answer:

50 mg.

Explanation:

From the prescription, 240 ml amount is to be prepared containing 30 ml tussin syrup. As the frequency is 5 mL qid, it means 5mL of syrup is to be administered four times daily i.e. 20 mL daily. To calculate the amount of tussin taken daily,

<em>                          </em><em><u>30 mL tussin</u></em><em> = </em><em><u>X mL of tussin</u></em>

<em>                     240 mL solution    20ml solution</em>

⇒ 2.5 mL of tussin

5 ml tussin contains 100mg guafenesin,

So,

⇒ 2.5 ml of tussin contains 100x2.5/5 = 50 mg guaifenesin

Alex777 [14]

Answer:

17. D. Chemical change

18. C. Cell wall

19. D. To transfer matter and energy within and between organisms.

20. A. Transporting materials

21. C. Carbon dioxide

22. A. Cellular respiration

23. C. Produce food and give off oxygen

Explanation:

I have been able to supply the correct answers. The cell wall functions as a structure that provides structural support and protection to the cell. It is tough, flexible and at times rigid. In a chemical change, new materials with new properties are manufactured. So, the process of photosynthesis is a chemical change.

The endoplasmic reticulum actually transports material. It transports materials like protein and lipids made within the cell and sends it to where they are needed.

Carbon dioxide  is the the gas that animals give off and plants use it during photosynthesis. Cellular respiration involves the activities that result to the breaking down of food in order to release energy.
