Order: Citalopram 20 mg PO q24hr
Available: Refer to the med label below
How many milliliters will you administer per dose? (Insert the numerical value only)
The Correct Answer is ["10"]
Desired dose = 20 mg
Available concentration = 10 mg per 5 mL
- Calculate the concentration in mg/mL:
Concentration (mg/mL) = Available dose / Available volume
= 10 mg / 5 mL
= 2 mg/mL
Volume to administer = Desired dose / Available concentration
= 20 mg / 2 mg/mL
= 10 mL

Correct Answer is D
Explanation
A. They inhibit the metabolism of alcohol in the liver: Benzodiazepines do not affect alcohol metabolism. Enzymes like alcohol dehydrogenase and aldehyde dehydrogenase are responsible for metabolizing alcohol, and benzodiazepines have no role in this process.
B. They block the reuptake of dopamine in the central nervous system: This mechanism is more characteristic of stimulant drugs like cocaine or certain antidepressants. Benzodiazepines act primarily on GABAergic pathways and do not target dopamine reuptake.
C. They have no potential for abuse or dependence: Benzodiazepines carry a well-documented risk of dependence and abuse, especially with long-term use or in individuals with a history of substance use disorders. Their use in alcohol withdrawal is carefully managed due to this risk.
D. They enhance the effects of GABA in the central nervous system: Benzodiazepines potentiate GABA, the brain’s primary inhibitory neurotransmitter, which helps to stabilize the CNS, reduce seizures, and manage agitation during alcohol withdrawal. This GABAergic action compensates for the decreased inhibitory tone seen in alcohol-dependent individuals during withdrawal.
Correct Answer is ["480"]
Explanation
Given quantity = 16 ounces
Desired unit = mL (milliliters)
Convert from ounces to millilitres
1 ounce = 30 mL
16 ounces × 30 mL/ounce
= 480 mL
