Death by opiate overdose is generally the result of __________.
Most opiates can cause respiratory depression when taken in toxic levels. They do this by reducing the sensitivity of respiratory center neurons to carbon dioxide, which results in decreased breathing. In more moderate cases brain damage can precede death due to CNS hypoxia. Opiates generally are not associated with liver failure (unless taken as a combination drug with acetaminophen, such as hydrocodone), heart attack, or serotonin syndrome.

You are the nurse in a primary care clinic taking care of a 26-year old female with a urinary tract infection. You are counseling her about taking her antibiotic, cephalexin. You warn her that a common side effect is which of the following?
The correct answer is "diarrhea." Diarrhea is a common side effect associated with antibiotic use, including cephalexin. This diarrhea is typically self-limited and resolves within the first day or two of administration. Sometimes patients are advised to take a probiotic or consume yogurt when starting a new antibiotic if they experienced diarrhea when starting antibiotics in the past.
Neither headaches, hair loss, pharyngitis, nor necrotizing skin rash are known common side effects of cephalexin use.

A 42 year old man with a history of severe depression who is currently prescribed multiple antidepressants presents with tachycardia, hyperreflexia, sweating, mydriasis, myoclonus. He is confused and mildly agitated. On questioning he admits that he may have taken "one too many" of one or more of his medications. What is the most likely cause of his symptoms?
The symptoms this patient are presenting with are consistent with serotonin syndrome, a rapid onset and potentially life-threatening condition of excess circulating serotonin. Symptoms can range from mild to severe, and may include tachycardia, nausea and vomiting, diarrhea, hyperreflexia, sweating, mydriasis, myoclonus, mental status changes, headache, and coma. Serotonin syndrome is generally caused by drug interaction or overdose of drugs that raise circulating serotonin levels, such as selective serotonin reuptake inhibitors (SSRI's) and monoamine oxidase inhibitors (MAOI's).

Which of the following best describes extrapyramidal side effects?
Extrapyramidal side effects generally present as slow or repetitive motions or postures (dystonia), spasm, tremor, slurred speech, slowed thought process, restlessness and anxiety, paranoia, and general overall distress. These effects are caused by antipsychotic drugs that act as dopamine D2 receptor antagonists.
Compare your answer with the correct one above
Which of the following drugs would be least likely to cause extrapyramidal side effects?
Extrapyramidal side effects are common with typical antipsychotic drugs that act as dopamine D2 receptor antagonists. These include many selective serotonin reuptake inhibitors (SSRI's), serotonin–norepinephrine reuptake inhibitors (SNRI's), and norepinephrine–dopamine reuptake inhibitors (NDRI's), as well as antiemetics such as metclopramide.
Alprazolam is a benzodiazepine and is not associated with extrapyramidal adverse effects.

A 63 year old female presents with involuntary grimacing, lip smacking, excessive blinking, and sticking out of the tongue. She also flicks her fingers and her wrists. She states that she has no control over these movements, and that they have gotten progressively worse over the last three years. Her family is worried that she may be experiencing an early form of dementia. Her medical history is significant for depression, for which she has been taking aripiprazole for the last nine years. Which of the following is the most likely cause of her symptoms?
The most likely cause of uncontrollable muscle movements in the absence of other systemic symptoms in a patient with a history of antipsychotic drug use is tardive dyskinesia. This is a disorder of rapid involuntary movements, most often in the face or head but also potentially affecting the extremities. It's exact cause is not well understood, but it is theorized to be an issue of sensitization of the D2 dopamine receptors after long-term neuroleptic use.

Which of the following over-the-counter medications has been associated with hepatotoxicity and liver failure?
Acetaminophen has surpassed viral hepatitis as the most common cause of acute hepatic failure in the United States. Hepatotoxicity can occur in doses of 7.5g or up for adults and 150millg/kg of body weight in children aged 1-6. None of the other drugs listed are particularly hepatotoxic.

What is the mechanism of cytotoxicity in acetaminophen-related liver failure?
Acetaminophen depletes glutathione, one of the body's most important antioxidants. The liver is the body's main processing organ for environmental and ingested toxins, and glutathione is the primary molecule the liver uses to rid itself of the harmful biproducts of the detoxification process. When glutathione is severely depleted, such as with acetaminophen overdose, hepatic cells can rapidly necrose, resulting in liver failure and even death.

A nurse is working with a 36 year old patient comes in for a back injury after a motor vehicle accident. He is prescribed oxycodone-acetaminophen for pain relief. Three days later he calls the nurse to complain that he is experiencing itching all over. He is concerned that he might be having an allergic reaction to the pain medication. There is no rash associated with his pruritus. He has no hives, no nausea or vomiting, no shortness of breath, no swelling of the mouth or face. What is the most likely cause of his itching?
Many opiates stimulate histamine release by mast cells. The cause of this stimulation remains unclear, but it is considered to be a non-immunological (therefore, not an allergy). There is some speculation that opiates trigger the release of histamine from mast cells by directly activating G proteins on mast cell surfaces. Opiates are not generally associated with kidney failure, and the most common symptoms in opiate allergy include hives, flushing, hives, low blood pressure, gastrointestinal discomfort (though constipation is typical in most patients and does not indicate allergic reaction), and angioedema.
