Romazicon, also known as flumazenil, is a benzodiazepine antagonist that can reverse the effects of benzodiazepine overdose by blocking its receptors in the brain. Acetylcysteine is used to treat acetaminophen overdose, Digibind is used to treat digitalis toxicity, and acetaminophen is not a treatment for benzodiazepine overdose.

Question 3

A nurse is teaching a student nurse about common treatments for victims of bioterrorism. The nurse tells the student that atropine would be most useful for a victim of bioterrorism exposed to which of the following?

Accepted Answer

Atropine is a medication commonly used to treat the effects of nerve gas exposure, such as excessive salivation, sweating, muscle twitching, and respiratory distress. It works by blocking the action of a neurotransmitter called acetylcholine, which is responsible for these symptoms. Atropine would not be useful for someone exposed to ionizing radiation or viral agents, and while it may be used in some cases of bacterial infection, it is not typically a primary treatment for such exposure.

Question 4

Select all that apply.

Accepted Answer

Gastric lavage and activated charcoal are contraindicated if the client is unconscious due to risk of aspiration, if lithium was ingested as charcoal does not bind well with lithium, and if more than 1-2 hours have passed since ingestion as the substance may have already moved beyond the stomach.

Question 8

A nurse is caring for a client following a bioterrorism attack. The client has experienced initial nausea and vomiting followed by weight loss and eventual thyroid cancer. What was the most likely causative agent?

Accepted Answer

The symptoms of nausea and vomiting followed by weight loss and thyroid cancer suggest exposure to ionizing radiation, which is known to cause these effects. Chemical agents and bacterial agents do not typically cause cancer, and while some viruses can cause cancer, they typically do not cause the initial symptoms described.

Question 9

A client was exposed to ionizing radiation. The nurse plans to administer which of the following medications?

Accepted Answer

Potassium-iodine tablets are used to prevent radioactive iodine from entering the thyroid gland and causing damage. Calcium tablets, antibiotics, and salt tablets would not be effective in treating radiation exposure.

Question 10

A nurse is caring for a client admitted to the emergency department following a drug overdose. The nurse anticipates which of the following prescriptions to enhance removal of the poison from the client? Note: Credit will be given only if all correct choices and no incorrect choices are selected. Select all that apply.

Accepted Answer

Activated charcoal is used to absorb the poison in the gastrointestinal tract. Changing the pH of urine can enhance the excretion of certain drugs. Enemas can help remove toxins from the lower gastrointestinal tract. A nasogastric tube can be used for gastric lavage to remove ingested substances. Corticosteroids are not used for poison removal.
