A nurse is providing care for a client experiencing obstructive shock. Which of the following diagnoses should the nurse expect?

A.

Cardiac tamponade

B.

Third spacing

C.

Ruptured aneurysm

D.

Cardiomyopathy

Answer and Explanation

The Correct Answer is A

A. Cardiac tamponade is a condition where fluid accumulates in the pericardial space, exerting pressure on the heart and impeding its ability to pump effectively, leading to obstructive shock.  

 

B. Third spacing refers to fluid accumulation in the interstitial spaces but is not a specific diagnosis of obstructive shock.  

 

C. A ruptured aneurysm may lead to hypovolemic shock due to blood loss rather than obstructive shock, which is characterized by physical obstruction to blood flow.  

 

D. Cardiomyopathy is a disease of the heart muscle that affects its ability to pump blood, leading to cardiogenic shock, not obstructive shock.

Correct Answer is C

Explanation

A. Obstructive shock occurs when blood flow is physically obstructed, such as in cases of pulmonary embolism or cardiac tamponade, which is not indicated here as the cause is blood loss.

B. Septic shock is related to infection and systemic inflammatory response, not directly caused by blood loss.

C. Hypovolemic shock is caused by a significant loss of blood volume, leading to decreased blood pressure, which directly relates to the client losing 800 mL of blood during surgery. This condition results in inadequate perfusion and oxygen delivery to tissues.

D. Neurogenic shock results from spinal cord injuries leading to vasodilation and bradycardia, which is not applicable to this scenario.

Correct Answer is C

Explanation

A. DIC is characterized by a low platelet count due to the consumption of platelets in the coagulation process, not an elevated count.

B. While heparin may be used in the management of DIC in some cases, it is not a lifelong treatment nor a cure for the condition, as DIC results from an underlying condition rather than being a standalone disease.

C. DIC involves the overactivation of the coagulation cascade, leading to the formation of fibrin clots and subsequent consumption of clotting factors and platelets, thus making this statement accurate.

D. DIC is not a genetic disorder but rather a complication often associated with severe infections, trauma, or other conditions, and it is not primarily due to vitamin K deficiency.
