A nurse is preparing to administer hydrocortisone 60 mg IV bolus to a child. The amount available is hydrocortisone 100 mg powder. Reconstituting with 2 mL of bacteriostatic water yields hydrocortisone 50 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if applicable. Do not use a trailing zero.)
The Correct Answer is ["1.2"]
To calculate this, divide the dose of hydrocortisone in mg by the concentration of the reconstituted hydrocortisone to find the volume to administer: 60 mg / (50 mg/mL) = 1.2 mL.

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.
Correct Answer is ["1.1"]
Explanation
First, we need to calculate the total daily dose of methimazole for the child.
The child weighs 55 kg and the prescribed dose is 0.3 mg/kg/day, so the total daily dose is 55 kg * 0.3 mg/kg/day = 16.5 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: 16.5 mg/day / 3 = 5.5 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: 5.5 mg per dose / 5 mg per tablet = 1.1 tablets per dose.
