A nurse is planning to administer lithium 1.8 g PO daily to a client. How many mg should the nurse administer? (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 ["1800"]
-Step 1: Define the conversion factor from grams to milligrams. We know that 1 g = 1000 mg.
-Step 2: Multiply 1.8 g by the conversion factor (1000 mg/g). The calculation is 1.8 g × 1000 mg/g = 1800 mg.
-Step 3: Round the result to the nearest whole number. The rounded result is 1800 mg.
The nurse should administer 1800 mg of lithium.

Correct Answer is ["3.1"]
Explanation
Given:
- Total perphenazine to be administered: 200 mg
- The medication is to be divided into four equal doses
- Available perphenazine oral solution: 16 mg/mL
Step 1: Calculate the amount of perphenazine per dose
200 mg ÷ 4 = 50 mg/dose
Step 2: Calculate the volume of the oral solution per dose
(50 mg/dose) ÷ (16 mg/mL) = 3.125 mL/dose
Rounding to the nearest tenth, the nurse should administer 3.1 mL
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.
