What is the initial therapy of choice for the treatment of anaphylactic shock?

Choice A reason: Tachycardia. In late septic shock, the body attempts to compensate for poor perfusion and low blood pressure by increasing the heart rate. Tachycardia is a common finding as the heart tries to pump more blood to the tissues.

Choice B reason: Lethargic mental status. As septic shock progresses, decreased perfusion to the brain can lead to changes in mental status, such as lethargy or confusion. This reflects the severity of the condition and the impact on the central nervous system.

Choice C reason: Anuria. Anuria, or the absence of urine output, occurs in late septic shock due to severe hypoperfusion and failure of the kidneys. It is a critical sign indicating that the body's organs are shutting down.

Choice D reason: Normal blood pressure. In late septic shock, blood pressure is typically very low due to systemic vasodilation and fluid loss. Normal blood pressure would not be expected at this advanced stage.

Choice E reason: Warm flushed skin. Warm flushed skin is associated with the early stages of septic shock when vasodilation leads to increased blood flow to the skin. In late septic shock, the skin is more likely to be cool and pale due to poor perfusion.

Choice A reason: Epinephrine. Epinephrine is the first-line treatment for anaphylactic shock. It rapidly reverses severe allergic reactions by reducing swelling, increasing blood pressure, and improving breathing.

Choice B reason: Rapid infusion of normal saline. While fluid resuscitation is important in managing anaphylactic shock, it is not the initial therapy of choice. Epinephrine should be administered first to counteract the allergic reaction.

Choice C reason: Dobutamine. Dobutamine is used to support cardiac function in certain types of shock but is not the first-line treatment for anaphylactic shock.

Choice D reason: Norepinephrine. Norepinephrine is a vasopressor used to treat severe hypotension and shock but is not the initial treatment for anaphylactic shock. Epinephrine is preferred to address the allergic reaction.
