A nurse is preparing to administer meperidine 35 mg IM to a client every 6 hr PRN for pain.
Available is meperidine injection 75 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a
trailing zero.)
The Correct Answer is ["0.5"]
Given:
Dose required = 35 mg
Concentration of medication = 75 mg/mL Formula:
Volume (mL) = Dose required (mg) / Concentration of medication (mg/mL) Calculation:
Volume (mL) = 35 mg / 75 mg/mL Result:
Volume (mL) = 0.4666667 mL Rounded to the nearest tenth:
Volume (mL) ≈ 0.5 mL

Correct Answer is A
Explanation
A. Carbidopa prevents the breakdown of levodopa in the periphery, specifically in the gastrointestinal tract and peripheral tissues, allowing more levodopa to reach the brain and be converted to dopamine. This enhances the effectiveness of levodopa therapy in managing the symptoms of Parkinson's disease.
B. Carbidopa is not the biologic precursor of dopamine. It is a peripheral decarboxylase inhibitor that does not cross the blood-brain barrier.
C. Carbidopa does not directly allow for larger doses of levodopa to be given. However, by
inhibiting the peripheral breakdown of levodopa, it enhances the availability of levodopa to the central nervous system, potentially improving therapeutic efficacy.
D. While levodopa-carbidopa combination therapy may have fewer drug-food interactions compared to levodopa alone, the primary reason for combining these medications is to enhance the effectiveness of levodopa by preventing its peripheral breakdown.
Correct Answer is B
Explanation
A. Bupropion is primarily used as an antidepressant and smoking cessation aid. It is not typically used for opioid withdrawal.
B. Methadone is a synthetic opioid agonist commonly used in the management of opioid withdrawal. It helps to alleviate withdrawal symptoms and can be used as part of a long-term maintenance program for opioid dependence.
C. Disulfiram is used in the treatment of alcohol dependence by creating unpleasant effects when alcohol is consumed. It is not indicated for opioid withdrawal.
D. Phenobarbital is a barbiturate with sedative and anticonvulsant properties. While it can be used to manage certain withdrawal symptoms, such as seizures associated with alcohol withdrawal, it is not typically used as a first-line treatment for opioid withdrawal.
