Chapter 15 Questions
Question 1 of 5
The nurse is caring for a client exposed to a blistering agent. While the nurse is quickly decontaminating the client by showering and bagging all client clothing, what is the nurse simultaneously assessing for?
Correct Answer: B
Rationale: A person exposed to a blistering agent or vesicant must be decontaminated immediately, with clothing removed and bagged. Irrigation of the victim's eyes and application of topical analgesia, antibiotics, and lubricants to the skin occur. Simultaneously, the nurse is assessing the respiratory system for airway obstruction because blisters from inhaled toxics can swell obstructing respiratory passages.
Question 2 of 5
The nurse is caring for a victim of a chemical disaster. Medications given in the treatment of this client include amyl nitrite, sodium nitrite, and sodium thiosulphate. What chemical agent does the nurse know this client has been exposed to?
Correct Answer: C
Rationale: Cyanide poisoning calls for the administration of one or all of the following antidotes: amyl nitrite, sodium nitrite, and sodium thiosulfate. Amyl nitrite promotes the formation of methemoglobin, which combines with cyanide to form nontoxic cyanmethemoglobin. Sarin, mustard gas, and anthrax are not treated in this way.
Question 3 of 5
The nurse is on a community awareness safety committee. When prioritizing biological agents according to potential morbidity and mortality, which cluster of biological agents hold the highest mortality?
Correct Answer: C
Rationale: The cluster of agents with the highest mortality includes anthrax and smallpox. The Hantavirus and tuberculosis agents are not presently used for bioterrorism. Botulism and Salmonella as well as Escherichia coli and Brucella species are of low mortality.
Question 4 of 5
The emergency department nurse is caring for clients involved in a chlorine exposure accident at a local chemical plant. The nurse is aware that permanent damage can occur to which body systems?
Correct Answer: B
Rationale: The consequences of exposure to chlorine and other respiratory toxins are related to the amount, route, and length of chemical exposure. Death occurs as fluid infiltrates the pulmonary air spaces and terminal bronchioles interfering with gas exchange. Following recovery from an acute event, victims may develop chronic bronchitis and emphysema.
Question 5 of 5
The nurse is orienting to the emergency department and finds cases of potassium iodide tablets located in the supply closet. The nurse asks the nurse manager, 'What is the purpose of this agent?' What is the nurse manager's best response?
Correct Answer: C
Rationale: The nurse manager's best response is, 'Potassium iodide is given to individuals as a prophylaxis for protecting the thyroid gland from absorption of radiation in case of an accident at the local nuclear plant,' because this best describes the rationale for keeping the medication on hand. The US Nuclear Regulatory Commission (NR
C) currently requires states with a population within 10 miles of a commercial nuclear plant to have immediate access to a supply of potassium iodide (KI) tablets.
