A nurse is preparing to administer 0.45% sodium chloride 1,000 mL IV to infuse over 8 hr. The nurse should set the IV pump to deliver how many mL/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 ["125"]
To find out how many mL/hr the IV pump should be set to deliver, we need to divide the total volume of the infusion by the infusion time in hours.
If 1,000 mL of 0.45% sodium chloride is to be infused over 8 hours, then the rate of infusion is 1,000/8 = 125 mL/hr.
The answer is rounded to the nearest whole number as instructed.

Explanation
Here's the detailed explanation: First, we need to convert the child's weight from pounds (lb) to kilograms (kg) since
the prescribed dose is in mg/kg/day.
There are approximately 2.2 lb in 1 kg, so the child's weight in kg is 55 lb / 2.2 = 25 kg. Next, we need to calculate the total daily dose of methimazole for the child.
The prescribed dose is 0.3 mg/kg/day, so the total daily dose is 25 kg * 0.3 mg/kg/day = 7.5 mg/day.
Since the medication is to be divided into equal doses every 8 hours, we need to divide the total daily dose by 3 to get the dose per administration: 7.5 mg/day / 3 = 2.5 mg per dose.
Finally, since each tablet contains 5 mg of methimazole, we need to divide the dose per administration by the amount of medication per tablet: 2.5 mg per dose / 5 mg per tablet = 0.5 tablets per dose.
Correct Answer is A
Explanation
A troche is a type of lozenge that is designed to dissolve slowly in the mouth to release medication over time.
The nurse should instruct the client to place the troche in their mouth and allow it to dissolve slowly without chewing or swallowing it.
The client should also avoid eating or drinking anything until the troche has completely dissolved to ensure maximum absorption of the medication.
The other options are incorrect because they do not accurately describe how a troche should be taken.
Option b is incorrect because it does not specify how the troches should be taken, only the timing of the doses.
Option c is incorrect because it instructs the client to keep the troche under the tongue for only 5 minutes before swallowing it, which may not allow enough time for the troche to dissolve completely and release its medication.
Option d is incorrect because it instructs the client to swallow the troche with water, which would prevent the
medication from being absorbed through the mucous membranes in the mouth and may reduce its effectiveness.
