A nurse is preparing to administer trazodone 300 mg PO daily, divided equally every 8 hours, to a client who has depression. Available are trazodone 50 mg tablets. How many tablets should the nurse administer in each dose? (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 ["2"]
Step 1: The total daily dose to be administered is300 mg of trazodone.
Step 2: The total daily dose is divided equally every 8 hours, so each dose is one third of the total daily dose. So, 300 mg ÷ 3 =100 mg per dose.
Step 3: The available trazodone tablets have a concentration of50 mg/tablet. This means that for every 1 tablet, there are 50 mg of trazodone.
Step 4: To find out how many tablets should be administered per dose, we divide the dose by the concentration. So, 100 mg ÷ 50 mg/tablet =2 tablets.
The nurse should administer 2 tablets of trazodone in each dose.

Correct Answer is A
Explanation
Choice A reason: The buccal route involves placing the medication directly in the mouth against the mucous membranes of the cheek, allowing for absorption through the oral tissues. This method is used for fentanyl administration to ensure rapid onset of pain relief without gastrointestinal involvement.
Choice B reason: Chewing the medication is not recommended for buccal administration as it can lead to unpredictable absorption and potential destruction of the medication's integrity, which can alter its effectiveness.
Choice C reason: Mixing fentanyl with food is not appropriate for buccal administration. This method is generally used for oral medications that are swallowed, not for those intended for mucosal absorption.
Choice D reason: Dissolving the tablet in liquid is also not suitable for buccal administration. The buccal route is designed for direct absorption through the cheek's mucous membranes, and dissolving the tablet would be more akin to oral administration, which is not the intended method for this medication.
Correct Answer is ["0.5"]
Explanation
The nurse needs to administer 50 mg of amitriptyline and each tablet contains 100 mg.
Step 1 is: Calculate the number of tablets by dividing the required dose by the dose available per tablet.
So, 50 mg (required dose) ÷ 100 mg/tablet (dose per tablet)
Step 2 is: Perform the division.
This gives us 0.5 tablets.
Step 3 is: Round the answer to the nearest tenth as instructed.
So, 0.5 rounded to the nearest tenth is 0.5.
