Med Surg (Chapter 9) Shock

Which of the following best describes the primary consequence of shock if not promptly treated?

• Increased oxygen supply to tissues.

• Cellular and tissue hypoxia leading to organ failure.

• Enhanced metabolic activity in tissues.

• Immediate recovery without intervention.

Shock occurs when compensatory mechanisms fail to maintain blood pressure and tissue perfusion. Which of the following mechanisms is not one of the primary factors that maintain blood pressure and tissue perfusion?

• Adequate blood volume

• Effective cardiac pump

• Effective blood vessel tone

• Increased respiratory rate

What hormone is released during the initial stage of shock to increase heart rate and cardiac output?

• Insulin

• Epinephrine

• Cortisol

• Glucagon

Which organ system receives less blood flow during the early stage of shock to preserve blood for vital organs?

• Brain

• Heart

• Intestines

• Lungs

What is a potential consequence of inadequate circulation to the intestines during shock?

• Paralytic ileus

• Improved digestion

• Increased nutrient absorption

• Enhanced bowel movement

A patient in the pre-shock (compensated) stage is likely to exhibit which of the following findings?

• Bradycardia with a weak pulse

• Tachycardia with bounding pulses

• Slowing heart rate with absent pulses

• Greater than 150 beats/min with weak, thready pulses

In the progressive stage of shock, which clinical finding is most likely to indicate the failure of compensatory mechanisms?

• Bounding pulses

• Weak, thready pulses with tachycardia

• Bradycardia with normal perfusion

• Absent pulses with a slowing heart rate

Which statement reflects the most accurate understanding of the use of the Trendelenburg position in hypovolemic shock?

• It is the first-line position to improve cardiac output.

• It improves lung function and cerebral perfusion.

• It is used to decrease intracranial pressure.

• It enhances renal perfusion.

Which of the following findings is most characteristic of cardiogenic shock and differentiates it from other forms of shock?

• Hypotension

• Tachycardia

• Pulmonary edema

• Cool, clammy skin

What distinguishes distributive shock from hypovolemic shock?

• Both involve massive vasodilation.

• Distributive shock involves altered fluid distribution without actual fluid loss.

• Hypovolemic shock is caused by cardiac dysfunction.

• Distributive shock results from fluid loss due to hemorrhage.
