Shock Quiz 2

1. A 7-year old girl being managed for septic shock is still hemodynamically unstable after IV lactated Ringer solution at a rate of 40 mL/kg for the past hour. The next step should be to:

2. A 7-year-old patient with severe anaphylaxis in the ICU has increased cardiac output but severely reduced systemic vascular resistance. Which one of the following types of shock does this patient have?

3. A 9-year-old boy has obstructive shock due to blunt force trauma to the chest, which has precipitated cardiac tamponade. Which of the following interventions is recommended for the treatment of shock in this case?

4. A leading cause of cardiogenic shock is decreased stroke volume. Which of the following can compromise stroke volume?

5. A pediatric patient in shock can still present with normal blood pressure due to increased systemic vascular resistance. How does one evaluate clinically if the patient is in shock despite a normal blood pressure?

6. A pediatric patient is in shock secondary to cardiac tamponade due to blunt-force trauma sustained in a motor vehicle collision. The restrictive nature of this medical condition causes which type of shock?

7. A pediatric patient undergoes a successful rescusitation for cardiac arrest due to sepsis. After the return of spontaneous circulation, she remains hypotensive. Broad-spectrum antibiotics are initiated. What is the cornerstone of treatment in this case?

8. After being stung by a bee, a 4-year-old girl suddenly develops breathing abnormalities, central cyanosis, hypotension, generalized edema, tachycardia, and tachypnea. What is your presumptive diagnosis?

9. Afterload is affected by which of the following physiologic factors?

10. An 8-year-old boy is resting in the pediatric ward after undergoing an open reduction internal fixation of a femur fracture due to a fall. After 3 days of recovery, the patient suddenly develops difficulty breathing and goes into obstructive shock. What is the likely cause of shock in this case?
