Explanation

Active tuberculosis classically presents with insidious, non-specific constitutional symptoms due to the body's systemic inflammatory response to the infection.
This option correctly lists the hallmark constitutional symptoms: fatigue, night sweats (often drenching), chills, and a low-grade fever that typically peaks in the afternoon.
These symptoms, along with weight loss and anorexia, are key indicators for suspecting TB, especially when accompanied by a persistent cough.

Option B: Diarrhea and dehydration are primary symptoms of gastrointestinal infections, such as gastroenteritis or cholera, not active pulmonary TB.
Option C: Nausea and vomiting are non-specific symptoms that can be caused by many conditions, including gastritis, food poisoning, or as side effects of medication. They are not primary symptoms of the TB disease process itself.
Option D: Abdominal pain and vomiting point towards an acute abdominal issue, such as appendicitis, pancreatitis, or a bowel obstruction, rather than a primary pulmonary infection.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Clinical Manifestations of Active Tuberculosis as background academic context rather than a clinical decision trigger.
Recognizing the classic constitutional symptoms of TB is a critical nursing skill for early suspicion, prompt implementation of airborne precautions, and preventing nosocomial transmission.
Nurses are central to patient education on the importance of completing the full course of multi-drug therapy (often 6 months or longer) to cure the disease and prevent the emergence of drug-resistant strains (MDR-TB).
What if? If a patient presents with these symptoms and is also immunocompromised (e.g., living with HIV, on chemotherapy), the nurse should have an even higher index of suspicion, as the disease can progress much more rapidly and present atypically.

How to Approach the Question

First, analyze the question to identify the core concept being tested, which is the 'main symptoms' of 'Active TB'. The word 'main' suggests you should focus on the most common and characteristic presentation.
Recall the pathophysiology of tuberculosis. It is primarily a lung disease that elicits a strong systemic inflammatory response.
Evaluate each option based on this knowledge. Option A lists classic systemic (constitutional) symptoms associated with chronic infections.
Options B, C, and D list symptoms primarily related to the gastrointestinal system.
Differentiate between the most common form of TB (pulmonary) and less common forms (extrapulmonary). The 'main' symptoms refer to the typical presentation of pulmonary TB.
Conclude that the constitutional symptoms in Option A are the most fitting description of active TB's main clinical picture.
