true/false
if you believe the statement to be more true than f

Explanation:

• For question 14: In decompensated shock, the body's compensatory mechanisms fail. Blood pressure is often the last vital sign to change as the body tries to maintain perfusion to vital organs until it can no longer. Heart rate, respiratory rate, and oxygen saturation change earlier as the body attempts to compensate for the shock state.
• For question 15: Anaphylactic shock is an allergic reaction. There is no blood loss in anaphylactic shock. It is caused by an allergic reaction (not lack of red - blood cells), associated with bronchoconstriction (not bronchodilation), and not due to myocardial pump failure.
• For question 16: A mild allergic reaction is less likely to cause shock compared to multiple severe fractures (which can lead to hypovolemic shock from blood loss), a severe infection (septic shock), or abdominal or chest injury (which can lead to hypovolemic or other types of shock).
• For question 17: When treating an unstable shock patient, vital signs should be recorded approximately every 5 minutes to closely monitor the patient's condition and response to treatment.
• For question 18: In cardiogenic shock, the heart cannot pump effectively. A strong, bounding pulse is not a sign of cardiogenic shock. Cyanosis (due to poor oxygenation), nausea, and anxiety can be present.
• For question 19: Psychogenic shock is a sudden reaction of the nervous system that produces temporary vascular dilation and fainting. Neurogenic shock is due to nerve damage, vascular shock is a more general term, and cardiogenic shock is due to heart failure.
