A nurse is planning a staff education session regarding biological weapons of mass destruction. Which of the following should he plan to include in the session? (Select all that apply.)
Smallpox
Hydrogen cyanide
Botulism
Anthrax
Sarin
Correct Answer : A,C,D
Choice A Reason: This is correct because smallpox is a highly contagious and deadly viral disease that can be used as a biological weapon. Smallpox was eradicated in 1980, but some samples of the virus are still stored in laboratories. If released intentionally, smallpox could cause a global pandemic.
Choice B Reason: This is incorrect because hydrogen cyanide is a chemical weapon of mass destruction, not a biological one. Hydrogen cyanide is a colorless gas that interferes with cellular respiration and causes rapid death.
Choice C Reason: This is correct because botulism is a serious and potentially fatal illness caused by a toxin produced by the bacterium Clostridium botulinum. Botulism can be used as a biological weapon by contaminating food or water supplies or by aerosolizing the toxin.
Choice D Reason: This is correct because anthrax is an infection caused by the spore-forming bacterium Bacillus anthracis. Anthrax can be used as a biological weapon by releasing the spores into the air or by contaminating food or water sources.
Choice E Reason: This is incorrect because sarin is a chemical weapon of mass destruction, not a biological one. Sarin is a nerve agent that blocks the transmission of nerve impulses and causes respiratory failure and death.

Correct Answer is B
Explanation
The correct answer is: B. Initiate oxygen therapy.
Choice A reason:
Attaching the leads for a 12-lead ECG is crucial for diagnosing a myocardial infarction. However, it is not the first priority. Ensuring the patient receives adequate oxygen is more critical to prevent further myocardial damage. The ECG can be performed immediately after oxygen therapy is initiated to confirm the diagnosis and guide further treatment.
Choice B reason:
Initiating oxygen therapy is the first priority because it ensures that the heart muscle receives adequate oxygen, which is essential to prevent further damage during a myocardial infarction. Oxygen therapy helps to maintain tissue oxygenation and can reduce the extent of myocardial injury. This immediate intervention is vital to stabilize the patient and improve outcomes.
Choice C reason:
Inserting the IV catheter is important for administering medications and fluids. However, it is not the first step. Oxygen therapy takes precedence to ensure the heart and other vital organs receive sufficient oxygen. Once oxygen is administered, IV access can be established to facilitate further treatment.
Choice D reason:
Obtaining a blood sample is necessary for confirming the diagnosis and assessing cardiac markers. However, it is not the immediate priority. Ensuring the patient is oxygenated is more urgent to prevent further myocardial damage. Blood samples can be drawn after oxygen therapy is initiated.
Correct Answer is B
Explanation
Choice a) is incorrect because troponin is not an enzyme, but a protein. Enzymes are molecules that speed up chemical reactions in the body. Troponin does not have this function.
Choice b) is correct because troponin is a protein that binds to calcium and regulates the contraction of heart muscle fibers. When the heart muscle is injured, such as in a myocardial infarction, troponin leaks into the bloodstream and can be detected by a blood test. The higher the level of troponin, the more severe the damage to the heart.
Choice c) is incorrect because troponin does not help transport oxygen throughout the body. That function is performed by hemoglobin, which is a protein found in red blood cells.
Choice d) is incorrect because troponin is not a lipid, but a protein. Lipids are fats that are used for energy storage and cell membrane formation. Troponin does not have these roles.
