Order: Digoxin 0.25 mg
On hand: 250 mcg tablets
How many tablets will the nurse give?
No answer is provided
1
No answer is too low
No answer is too high
No answer is too high
The Correct Answer is B
This choice is correct because it is the result of dividing the ordered dose (0.25 mg) by the strength of the tablet (250 mcg or 0.25 mg). The formula for calculating the number of tablets to be given is:
Tablets = Dose/ Strength
Therefore, the number of tablets to be given is:
Tablets = 0.25 mg/250 mcg = 0.25 mg/0.25 mg = 1

Correct Answer is A
Explanation
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.
Correct Answer is ["1.1 mL"]
Explanation
To calculate the amount of cefazolin that the nurse should add to the 50 mL of 0.9% sodium chloride, we can use the following steps:
Calculate the amount of cefazolin needed to prepare the solution:
The concentration to be achieved is 225 mg/mL.
The required dose is 250 mg.
Calculate the volume of cefazolin needed:
250 mg ÷ 225 mg/mL = 1.111... mL
Rounded to the nearest tenth, the nurse should add 1.1 mL of cefazolin to the 50 mL of 0.9% sodium chloride.
Therefore, the nurse should add 1.1 mL of cefazolin to the 50 mL of 0.9% sodium chloride to prepare the solution for IV administration.
