You are instructed to administer 40 mg of methadone (Dolophine) subcutaneously for opioid detoxification. Given that you have a concentration of 30 mg/mL on hand, how much should you draw into the syringe?

Rationale for Choice A:
Documentation is essential for communication and continuity of care, but it is not the most immediate priority in this situation.
The nurse should document the episode of vomiting, including the time, amount, and characteristics of the vomitus, as well as any associated symptoms or interventions.
However, auscultating lung sounds should be done first to assess for potential aspiration, which is a more urgent concern.
Rationale for Choice B:
Offering dry toast may be appropriate after the nurse has assessed for aspiration and determined that it is safe for the client to resume oral intake.
However, it is not the most important action at this time.
The nurse should first assess the client's respiratory status and address any potential complications.
Rationale for Choice C:
Rest is important for healing and recovery, but it is not the most immediate priority in this situation. The nurse should first assess the client's respiratory status and address any potential complications. Once the client is stable, the nurse can then encourage rest.
Rationale for Choice D:
Auscultating lung sounds is the most important action for the nurse to take after a client vomits.
This is because aspiration of vomitus is a serious complication that can lead to pneumonia, respiratory distress, and even death.
By auscultating lung sounds, the nurse can assess for signs of aspiration, such as crackles, wheezing, or diminished breath sounds.
If aspiration is suspected, the nurse can initiate appropriate interventions, such as suctioning, oxygen therapy, and positioning the client to facilitate drainage of secretions.

Choice A rationale:
Plague is a highly contagious and often fatal disease caused by the bacterium Yersinia pestis. It is transmitted to humans through the bites of infected fleas or by direct contact with infected animals or their tissues.
Plague can cause severe illness and death, even with prompt treatment. The mortality rate for untreated plague is 50-60%. Therefore, it is incorrect to state that plague produces a mild illness and generally has a low mortality rate.
Choice C rationale:
Smallpox is a highly contagious and deadly disease caused by the variola virus. It was eradicated in 1980, but there is still a risk that it could be used as a bioweapon.
Most people under the age of 40 have not been vaccinated against smallpox and therefore have no immunity to the disease. Therefore, it is incorrect to state that the majority of Americans have adequate innate immunity to smallpox.
Choice D rationale:
Safer food preparation practices have helped to decrease the incidence of foodborne illnesses.
However, foodborne illnesses can still be spread through international travel. Travelers can be exposed to contaminated food or water in other countries.

Therefore, safer food preparation practices do not eliminate the risk of foodborne illnesses being spread through international travel.
