A nurse is preparing to administer potassium chloride 40 mEq in dextrose 5% in 0.9% sodium chloride 1,000 mL IV to infuse over 8 hr. The tubing has a drop factor of 15 gtt/mL.
The nurse should set the IV flow rate to deliver how many gtt/min?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["31"]
To calculate the IV flow rate in drops per minute (gtt/min), we can use the following steps:
Calculate the total number of minutes for the infusion:
8 hours × 60 minutes/hour = 480 minutes
Determine the total number of drops needed for the infusion:
The total volume to be infused is 1000 mL.
The drop factor is 15 gtt/mL.
1000 mL × 15 gtt/mL = 15000 gtt
Calculate the IV flow rate in drops per minute:
15000 gtt ÷ 480 min ≈ 31 gtt/min
Rounding to the nearest whole number, the nurse should set the IV flow rate to deliver 31 gtt/min.

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 ["2500"]
Explanation
The nurse needs to administer 2.5 L of 0.45% sodium chloride IV over 24 hours.
We know that 1 L is equal to 1000 mL.
So, 2.5 L is equal to 2.5 x 1000 mL/L = 2500 mL
Therefore, the nurse should administer 2500 mL over 24 hours.
