A patient arrives with hypotension, fever, joint pain, petechiae on limbs, and respiratory distress. Which of the following is the most likely diagnosis?
Show Hint
Fever with hypotension and organ dysfunction suggests septic shock.
Updated On: May 14, 2026
- Disseminated gonococcal infection
- Septic shock
- Rheumatoid arthritis
- Septic arthritis
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
The patient presents with multi-organ involvement: circulatory (hypotension), systemic (fever, petechiae), musculoskeletal (joint pain), and respiratory (distress). This acute, severe presentation suggests an overwhelming systemic infection.
Step 2: Detailed Explanation:
Septic Shock Definition: A subset of sepsis in which particularly profound circulatory, cellular, and metabolic abnormalities are associated with a greater risk of mortality than with sepsis alone.
Clinical Correlation:
- Hypotension: Failure of the circulatory system.
- Petechiae: Suggest Disseminated Intravascular Coagulation (DIC), a common complication of severe sepsis and septic shock.
- Respiratory Distress: Suggests Acute Respiratory Distress Syndrome (ARDS) secondary to the systemic inflammatory response.
- Joint Pain: Can be a part of the systemic inflammatory response or due to bacteremia.
Meningococcemia: One of the most classic causes of this presentation (fever, shock, rapidly spreading petechial/purpuric rash) is Neisseria meningitidis infection.
Why not others? Septic arthritis (Option D) would typically involve a single swollen, hot joint without multi-organ failure. Disseminated gonococcal infection (Option A) usually causes a triad of tenosynovitis, dermatitis (a few sparse pustules), and polyarthralgia, but rarely causes frank hypotension and respiratory distress.
Step 3: Final Answer:
The global severity and presence of shock/respiratory failure indicate Septic Shock as the primary diagnosis.
