Parenteral C. Too little sugar in blood 4 Hypertension D. Non per Orem 5. Hypoglycemia E. Every other day F. High blood pressure Solve the following problems 1. How many millitiess of a 1:200 ml (v/v) stock solution should be used to make 4 liters of a 1:4000 (w/v) solution? 2. The strength of myrup USP solution is 65% iv/w and its specific gravity is 1.313. What is it s concentration in có whi

24. The specific gravity of glycerin is calculated as the ratio of its weight to the weight of an equal volume of water. Since the weight of glycerin is given as 1268 grams, and the weight of water is 46 grams, the specific gravity is 1268/46 = 27.6. Therefore, the correct answer is D. 3.5.

25. Ointments are calculated on a (w/w) % basis, which means the weight of the active ingredient is expressed as a percentage of the total weight of the ointment. Therefore, the correct answer is D. Ointments.

26. The statement "Water is standard for gases" is false. The standard for gases is typically taken as air, not water. Therefore, the correct answer is C. Water is standard for gases.

27. The concentration of the solution in terms of milliequivalents per milliliter can be calculated using the formula: (mass of KCl in grams / molecular weight of KCl) x (1,000 / volume of solution in mL). Plugging in the given values, we get (2.98 g / 74.5 g/mol) x (1,000 / 10 mL) = 40 mEq/mL. Therefore, the correct answer is C. 40 mEq/mL.

28. The specific gravity of the acid can be calculated using the formula: (weight in air - weight in water) / (weight in air - weight in sulfuric acid). Plugging in the given values, we get (14.35 g - 11.40 g) / (14.35 g - 8.95 g) = 1.83. Therefore, the correct answer is B. 1.83.

29. A proper fraction is a fraction in which the numerator is smaller than the denominator. Therefore, the statement "A proper fraction is a fraction in which the denominator is smaller than the numerator" is false. Therefore, the correct answer is B. False.

30. The ratio strength of 0.4% is calculated as 1 / (concentration in decimal form). For 0.4%, the ratio strength is 1 / 0.004 = 250. Therefore, the correct answer is A. 1:250.

Matching columns A with B:
1. EOD - E. Every other day
2. NPO - D. Non per Orem
3. Parenteral - A. Administration of drug by using injection
4. Hypertension - F. High blood pressure
5. Hypoglycemia - C. Too little sugar in blood

Solving the problems:
1. To make 4 liters of a 1:4000 (w/v) solution from an 81:200 ml (v/v) stock solution, we can use the dilution formula: C1V1 = C2V2. Plugging in the given values, we get (1/4000) x 4000 = (81/200) x V1. Solving for V1, we get V1 = 0.81 ml.
2. The concentration of the syrup USP solution in terms of weight/volume (w/v) can be calculated using the formula: (specific gravity x concentration in %) / 100. Plugging in the given values, we get (1.313 x 65) / 100 = 0.857 g/mL.
