NCLEX_CRUSADE_ACADEMY TEST - 17 BIOLOGYCAL_WARFARE_AGENTS

1. Biological warfare agents are primarily designed to cause mass destruction through which mechanism?. Mechanical trauma. High toxicity and infection potential. Radiation exposure. Allergic reactions.

2. Which organism is identified as the primary biological warfare agent in the learning module?. Mycobacterium tuberculosis. Clostridium botulinum. Bacillus anthracis. Staphylococcus aureus.

3. Bacillus anthracis is best described as which type of microorganism?. Virus. Spore forming bacterium. Protozoa. Fungus.

4. Which transmission route of anthrax is associated with the highest mortality rate?. Cutaneous exposure. Gastrointestinal ingestion. Inhalation of spores. Contact with contaminated surfaces.

5. Which symptom progression best describes cutaneous anthrax?. Vesicle rash blister scar. Itching papule vesicle painless ulcer black eschar. Rash ulcer necrosis blister. Blister bleeding lesion scar.

6. A key identifying feature of cutaneous anthrax is which lesion characteristic?. Painful blister with pus. Red rash with itching. Painless ulcer with black necrotic center. Raised nodular lesion.

7. Inhalation anthrax primarily damages which anatomical structure first?. Gastrointestinal tract. Skin layers. Alveolar lung tissue. Central nervous system.

8. Which symptom combination is most consistent with inhalation anthrax?. Rash and itching. Fever and sore throat. Chest discomfort, respiratory distress, shortness of breath. Diarrhea and vomiting.

9. Gastrointestinal anthrax is most commonly acquired through which exposure?. Contaminated water. Undercooked contaminated meat. Mosquito bite. Direct skin contact.

10. Which sign suggests severe gastrointestinal anthrax infection?. Mild stomach discomfort. Bloody vomiting or severe diarrhea. Constipation. Headache.

11. Which diagnostic test confirms the presence of Bacillus anthracis?. Urinalysis. Blood test confirming Bacillus anthracis. MRI scan. Stool culture.

12. Which antibiotics are commonly used to treat anthrax infection?. Ciprofloxacin, doxycycline, penicillin. Amoxicillin only. Metronidazole and vancomycin. Azithromycin.

13. Which nursing priority is emphasized for anthrax management?. Wait for culture confirmation. Early identification and intervention. Delay treatment until symptoms worsen. Provide supportive care only.

14. In an immunocompromised patient with HIV, what induration size on a tuberculin skin test indicates a positive result?. 5 mm. 10 mm. 15 mm. 20 mm.

15. A patient with HIV has an 8 mm induration on a PPD test. What is the nurses priority action?. Inform the patient the result is negative. Repeat the test in two months. Arrange a chest X ray. Begin multidrug TB therapy immediately.

16. A nurse sustains a needlestick injury from a patient with unknown HIV status. What is the correct action?. Ask the patient directly for testing. Draw blood immediately without consent. Contact Occupational Health. Ignore the injury if minor.

17. Why should the injured nurse not directly request HIV testing from the patient?. It delays treatment. It may create bias and violate proper chain of command. Testing is unnecessary. It increases infection risk.

18. Which NCLEX clinical reasoning principle is emphasized in the module?. Memorize disease names. Treat first and assess later. Assess, validate, then act. Ignore minor symptoms.
