A nurse is preparing to administer chlorpromazine 50 mg IM to a client. Available is chlorpromazine 25 mg/mL. How many mL 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 ["2"]
Step 1: The dose to be administered is50 mg of chlorpromazine.
Step 2: The available chlorpromazine injection has a concentration of25 mg/mL. This means that for every 1 mL of the solution, there are 25 mg of chlorpromazine.
Step 3: To find out how many mL should be administered, we divide the dose by the concentration. So, 50 mg ÷ 25 mg/mL = 2 mL.
The nurse should administer 2 mL of chlorpromazine injection.

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 ["12.5"]
Explanation
Step 1: The dose to be administered is75 mg of valproic acid.
Step 2: The available valproic acid syrup has a concentration of30 mg/5 mL. This means that for every 5 mL of the solution, there are 30 mg of valproic acid.
Step 3: To find out how many mL should be administered, we divide the dose by the concentration. So, 75 mg ÷ (30 mg/5 mL) = 12.5 mL.
The nurse should administer 12.5 mL of valproic acid syrup.
