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 B
Explanation
The correct answer is choice B: Dosage.
Choice A rationale: The medication name is an essential component of a medication prescription, identifying the specific medication to be administered. In this case, the medication name is already provided as "Zopiclone."
Choice B rationale: Dosage is a crucial element of a medication prescription, indicating the amount of the medication to be administered. Although the prescription mentions "1 tablet," the strength or dosage of the Zopiclone tablet (e.g., 5 mg, 7.5 mg) is missing. The nurse should ask the provider to specify the dosage to ensure accurate and safe medication administration.
Choice C rationale: Frequency refers to how often the medication should be taken. The given prescription states "at bedtime," which specifies when the medication should be administered.
Choice D rationale: Route describes the method used to administer the medication. This prescription mentions the route as "PO," which stands for "by mouth" (per os).
In conclusion, a nurse should ensure that a medication prescription includes all essential components, such as medication name, dosage, frequency, and route. In this case, the dosage of Zopiclone is missing, and the nurse should ask the provider to add this information to the prescription to ensure accurate and safe administration of the medication.
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.
