A nurse is assisting in providing care for a client who has obstructive shock. Which of the following diagnoses should the nurse expect?

Third spacing

Cardiac tamponade

Cardiomyopathy

Ruptured aneurysm

Answer and Explanation

The Correct Answer is B

A. Third spacing involves the abnormal accumulation of fluid in extracellular spaces and is more commonly associated with hypovolemic or distributive shock, not obstructive shock.

B. Cardiac tamponade is a classic cause of obstructive shock, where the accumulation of fluid in the pericardial sac compresses the heart, leading to decreased cardiac output and obstructed blood flow.

C. Cardiomyopathy is a disease of the heart muscle that can lead to heart failure but is typically associated with cardiogenic shock, not obstructive shock.

D. A ruptured aneurysm would most likely cause hypovolemic shock due to blood loss, not obstructive shock.
