Correct Answer is A

Explanation

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.

A. CD4-T-cell count 180 cells/mm3 B. Positive Western blot test C. Platelets 150,000/mm3 D. WBC 5,000/mm3

Correct Answer is A

Explanation

A. The CD4-T-cell count of 180 cells/mm3 is a critical measure of immune function in an HIV-positive client, indicating progression of the disease and risk for opportunistic infections. Values below 200 cells/mm3 signify the client has progressed to AIDS.
B. A positive Western blot test confirms the presence of HIV but does not indicate the immediate health risk or necessary interventions.
C. A platelet count of 150,000/mm3 is within the normal range, thus not indicative of any urgent concerns.
D. A WBC count of 5,000/mm3 is also within normal limits and does not highlight an immediate issue that needs addressing compared to the CD4 count.
