A nurse is preparing to administer rifampin 20 mg/kg/day PO in two divided doses to a client who weighs 132 lb and has tuberculosis. The amount available is rifampin 150 mg capsules. How many capsules should the nurse administer per dose?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason: This is correct. Somatropin is a synthetic form of human growth hormone (HGH), which stimulates the growth of bones and tissues. It is used to treat growth deficiency in children who have low or no natural HGH. The treatment is usually stopped when the growth plates (the areas of cartilage at the ends of the long bones) fuse, which marks the end of the growth period. This usually occurs around the age of 14-18 years for boys and 12-16 years for girls.

Choice B reason: This is incorrect. Somatropin is not intended for life-long treatment. It is only used to correct growth deficiency in children who have low or no natural HGH. Once the growth plates fuse, the treatment is discontinued.

Choice C reason: This is incorrect. Somatropin is not used for weight management. It is used to treat growth deficiency in children who have low or no natural HGH. The duration of the treatment depends on the individual growth potential and response to the medication, not on the weight goal.

Choice D reason: This is incorrect. Somatropin is not a short-term medication. It is used to treat growth deficiency in children who have low or no natural HGH. The treatment usually lasts for several years, until the growth plates fuse.

To calculate the amount of tobramycin that the nurse should administer per dose, we can use the following steps:

Calculate the total daily dosage required based on the client's weight and the prescribed dosage.

Determine the dosage per each of the three divided doses.

Calculate the volume of the drug needed for each dose using the concentration of the available tobramycin solution.

Given:

Client's weight = 85 kg

Prescribed dosage = 3 mg/kg/day

Available concentration of tobramycin = 40 mg/mL

Let's calculate step by step:

Calculate the total daily dosage required:

Total daily dosage = 3 mg/kg/day × 85 kg = 255 mg/day

Determine the dosage per each of the three divided doses:

Dosage per dose = Total daily dosage / 3 = 255 mg / 3 = 85 mg

Calculate the volume of the drug needed for each dose using the concentration of the available tobramycin solution:

Volume of drug per dose = Dosage per dose / Concentration of tobramycin

Volume of drug per dose = 85 mg / 40 mg/mL ≈ 2.1 mL

Rounding to the nearest tenth, the nurse should administer 2.1 mL of the tobramycin per dose.
