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

Answer and Explanation

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 D

Explanation

Choice A Reason: This is incorrect because this client has signs of brain death, such as severe head injuries, low respiratory rate, and unresponsiveness. The nurse should tag this client as black, which means deceased or expectant.

Choice B Reason: This is incorrect because this client has non-life-threatening injuries, such as a simple fracture and scratches. The nurse should tag this client as green, which means minor or delayed care.

Choice C Reason: This is incorrect because this client has minor injuries and is able to walk around. The nurse should tag this client as green, which means minor or delayed care.

Choice D Reason: This is correct because this client has a life-threatening condition called tension pneumothorax, which requires immediate care. This client has a life-threatening condition called tension pneumothorax, which is caused by air leaking into the pleural space and compressing the lung and the heart. This can lead to respiratory failure, cardiac arrest, and death if not treated immediately. The hissing sound indicates that air is escaping from the lung through the wound. The nurse should tag this client as red, which means immediate care is needed.

A. pH 7.50, HCO3- 20 mEq/L, PaCO2 32 mm Hg B. pH 7.55, HCO3- 30 mEq/L, PaCO2 31 mm Hg C. pH 7.50, HCO3- 26 mEq/L, PaCO2 50 mm Hg D. pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg

Correct Answer is D

Explanation

Choice A Reason: This is incorrect because these values indicate respiratory alkalosis, which is caused by hyperventilation or excess loss of carbon dioxide (PaCO2). Respiratory alkalosis increases the blood pH and decreases the HCO3- level.

Choice B Reason: This is incorrect because these values indicate metabolic alkalosis, which is caused by excess intake or retention of bases or loss of acids. Metabolic alkalosis increases the blood pH and the HCO3- level.

Choice C Reason: This is incorrect because these values indicate respiratory acidosis, which is caused by hypoventilation or excess retention of carbon dioxide (PaCO2). Respiratory acidosis decreases the blood pH and increases the HCO3- level.

Choice D Reason: This is correct because these values indicate metabolic acidosis, which is a common complication of chronic kidney disease. These values indicate metabolic acidosis, which is a common complication of chronic kidney disease. Metabolic acidosis occurs when the kidneys are unable to excrete excess acids or retain enough bicarbonate (HCO3-), which is a base that buﬀers the blood pH. As a result, the blood pH decreases and becomes more acidic. The normal range for blood pH is 7.35 to 7.45, for HCO3- is 22 to 26 mEq/L, and for PaCO2 is 35 to 45 mm Hg.
