A nurse is preparing to administer ketorolac 0.4 mg/kg IM to an adolescent who weighs 96.8 Ib. The amount available is ketorolac 15 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.2"]
To calculate this, first convert the adolescent's weight from pounds to kilograms: 96.8 lb * (1 kg / 2.2 lb) =
44 kg.
Then, calculate the dose of ketorolac in mg: 0.4 mg/kg * 44 kg = 17.6 mg.
Finally, divide the dose in mg by the concentration of the ketorolac to find the volume to administer: 17.6 mg / (15 mg/mL) = 1.173 mL, which rounds to 1.2 mL when rounded to the nearest tenth.

Correct Answer is ["3.5"]
Explanation
First, we need to convert the child's weight from pounds to kilograms.
Since there are approximately 2.20462 pounds in 1 kilogram, 52 pounds is equivalent to 52/2.20462 =
23.587 kilograms.
The prescribed dose of digoxin is 7.5 mcg/kg/day, so for a child who weighs 23.587 kg, the total daily dose is 7.5 * 23.587 = 176.9 mcg/day.
Since the medication is available as a 50 mcg/mL elixir, the nurse should administer 176.9/50 = 3.538 mL/day.
Since the medication is to be administered once daily, the nurse should administer 3.5mL per dose. The answer is rounded to the nearest tenth as instructed.
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.
