Epinephrine is used to treat cardiac arrest and status asthmaticus because of which of the following actions?
Increased speed of conduction and gluconeogenesis
Bronchodilation and increased heart rate, contractility, and conduction
Increased vasodilation and enhanced myocardial contractility
Bronchoconstriction and increased heart rate
The Correct Answer is B
Choice A rationale: Epinephrine does increase the speed of conduction, but it does not significantly contribute to gluconeogenesis.
Choice B rationale: Epinephrine is used in cardiac arrest to increase heart rate, contractility, and conduction. In asthma, it causes bronchodilation.
Choice C rationale: While epinephrine can cause some vasodilation, it is not a primary indication for its use in cardiac arrest or status asthmaticus.
Choice D rationale: Epinephrine causes bronchodilation, not bronchoconstriction.

Correct Answer is C
Explanation
Choice A rationale: Disorientation and hallucinations are not common side effects of fluoxetine. These symptoms may indicate other issues and should be reported to the healthcare provider.
Choice B rationale: Sexual side effects, including a potential decrease in interest in sex, are known side effects of fluoxetine. The statement suggesting enhanced interest is not accurate.
Choice C rationale: Fluoxetine, like other selective serotonin reuptake inhibitors (SSRIs), may take 3 to 4 weeks or even longer for the full therapeutic effect to be achieved.
Choice D rationale: Abruptly stopping fluoxetine is not recommended and can lead to withdrawal symptoms. The medication should be tapered under the guidance of a healthcare provider.
Correct Answer is B
Explanation
Choice A rationale: Nasal congestion is a common side effect of alpha1-adrenergic blockers, not a cause for concern.
Choice B rationale: Orthostatic hypotension is a potential adverse effect of alpha1- adrenergic blockers like prazosin. It can lead to dizziness and falls, particularly when moving from a lying or sitting position to a standing one.
Choice C rationale: Inhibition of ejaculation is a potential side effect of alpha1- adrenergic blockers but is not of the most concern compared to orthostatic hypotension.
Choice D rationale: Reflex tachycardia is not a typical adverse effect of alpha1- adrenergic blockers.
