A nurse is preparing to administer 7.5 mL of ampicillin 250 mg oral suspension to a toddler who has otitis media. The nurse should recognize that 7.5 mL is equivalent to how many teaspoons? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.5"]
7.5 mL is equivalent to 1.5 teaspoons.
To calculate this, use the conversion factor that 1 tsp is equivalent to 5 mL. So, 7.5 mL * (1 tsp / 5 mL) = 1.5 tsp.

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 ["4.2"]
Explanation
Step 1: Convert the preschooler’s weight from pounds to kilograms. 37 lbs ÷ 2.2 = 16.8181 kg (rounded to four decimal places)
Step 2: Calculate the total daily dose of cephalexin in mg. 50 mg/kg/day × 16.8181 kg = 840.905 mg/day (rounded to three decimal places)
Step 3: Determine the number of doses per day. 24 hours ÷ 6 hours = 4 doses/day
Step 4: Calculate the dose per administration. 840.905 mg/day ÷ 4 doses/day = 210.22625 mg/dose (rounded to five decimal places)
Step 5: Convert the dose from mg to mL using the available suspension concentration. 250 mg ÷ 5 mL = 50 mg/mL
Step 6: Calculate the volume to be administered per dose. 210.22625 mg ÷ 50 mg/mL = 4.204525 mL (rounded to six decimal places)
Step 7: Round the final answer to the nearest tenth. 4.204525 mL rounded to the nearest tenth = 4.2 mL
Therefore, the nurse should administer 4.2 mL per dose.
