A nurse is preparing to administer 12 L of lactated Ringer’s IV to infuse over 24 hr. Half of the fluid is to be administered in the first 8 hr. The nurse should set the IV pump to deliver how many mL/hr during the first 8 hr?
(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 ["750"]
To calculate the infusion rate for the first 8 hours, we can use the following formula:
Infusion rate (mL/hr) = (Volume to be infused / Time for infusion)
First, we need to find the volume to be infused in the first 8 hours:
Volume for the first 8 hours = Total volume / 2 = 12 L / 2 = 6 L = 6000 mL
Now we can calculate the infusion rate for the first 8 hours:
Infusion rate = 6000 mL / 8 hr = 750 mL/hr
Therefore, the nurse should set the IV pump to deliver 750 mL/hr during the first 8 hours.

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 ["0.75"]
Explanation
To calculate the amount of heparin to administer, we can use the following formula:
Amount to administer (mL) = (Desired dose (units) / Available dose (units/mL))
Plugging in the given values:
Amount to administer (mL) = (7,500 units / 10,000 units/mL)
Now, let's solve for the amount to administer:
Amount to administer (mL) = (7,500 / 10,000) = 0.75 mL
So, the nurse should administer 0.75 mL of heparin subcutaneously.
