Calculate the infusion time for an IV of 1,500 mL running at 25 gtt/min. if the drop factor is 15 gtt/mL.

A. Depression:

CNS stimulants are generally not indicated for depression. In fact, they can exacerbate symptoms and are not considered a first-line treatment for depressive disorders.

B. Opiate overdose:

CNS stimulants are not indicated for treating opiate overdose. In cases of overdose, other medications like naloxone are commonly used to reverse the effects of opioids.

C. Poor appetite:

CNS stimulants may be used to increase alertness and decrease fatigue, but they are not typically prescribed to address poor appetite. Appetite stimulation is often managed through other approaches.

D. Narcolepsy:

This is the correct answer. CNS stimulants, such as modafinil or methylphenidate, are commonly prescribed to manage symptoms of narcolepsy. These medications help improve wakefulness and reduce excessive daytime sleepiness.

A. Bradycardia

Bradycardia is not a common side effect of diphenoxylate with atropine. Atropine, which is included in the combination, has anticholinergic effects that can lead to an increased heart rate (tachycardia), not bradycardia.

B. Fluid retention

Fluid retention is not a common side effect of diphenoxylate with atropine. In fact, the medication is used to treat severe diarrhea, and the goal is to decrease fluid loss associated with diarrhea rather than causing fluid retention.

C. Nervousness and tremors

Nervousness and tremors are not common side effects of diphenoxylate with atropine. Atropine's anticholinergic effects may cause nervousness, but these effects are generally not prominent at therapeutic doses.

D. Respiratory depression

This is the correct choice. Respiratory depression is a potential side effect of diphenoxylate with atropine, particularly if the medication is misused or taken in excessive amounts. Atropine is included in the combination to discourage misuse, as it can cause unpleasant anticholinergic effects.
