1. life - threatening allergic reactions can occur even when a patient has previously tolerated a substance

without having an allergic reaction.

1. bleeding is a common cause of cardiogenic shock.
2. shock occurs when oxygen and nutrients cannot get to the bodys cells.
3. a person in shock, left untreated, will survive.
4. compensated shock will present with falling blood pressure.
5. an injection of epinephrine is the most effective treatment for anaphylactic shock.
6. septic shock occurs as a result of a severe infection.
7. metabolism is the cardiovascular systems circulation of blood and oxygen to all cells in different

tissues and organs of the body.

1. shock occurs only with massive blood loss from the body.
2. decompensated shock is a late phase of shock and indicates progression of shock toward irreversibility.

Explanation:

1. Allergic reactions can be unpredictable. A patient may have been exposed to a substance before without a reaction but later have a severe, life - threatening one (e.g., due to sensitization over time).
2. Cardiogenic shock is mainly caused by heart problems (e.g., myocardial infarction), not bleeding. Bleeding is more associated with hypovolemic shock.
3. Shock is defined as a state where the body's cells do not receive adequate oxygen and nutrients.
4. Shock, if untreated, usually leads to organ failure and death as the body's systems break down.
5. Compensated shock has normal or slightly low blood pressure as the body is still compensating (e.g., through vasoconstriction). Hypotension is more a sign of decompensated shock.
6. Epinephrine is the first - line treatment for anaphylactic shock as it reverses bronchoconstriction, vasodilation, and other allergic symptoms.
7. Septic shock is triggered by a severe infection (usually bacterial) that leads to a systemic inflammatory response.
8. Metabolism is the set of chemical reactions in the body (e.g., breaking down food, producing energy). The cardiovascular system's function is circulation, not metabolism.
9. Shock can be caused by various factors: hypovolemic (blood loss), cardiogenic (heart failure), distributive (e.g., anaphylactic, septic), etc.
10. Decompensated shock is the late stage where the body's compensatory mechanisms fail, and shock progresses towards a more irreversible state.
