NURS 6521N Week 5 Quiz 2.Q&A • Question 1 1 out of 1 points A homeless man who is well known to care providers at the local hospital has been admitted to the emergency department after having ... a seizure outside a mall. The man is known to be a heavy alcohol user and is malnourished with a very low body mass index. How are this patient's characteristics likely to influence possible treatment with phenytoin? Response Feedback: A protein deficit puts the patient at greater risk for having greater amounts of free, active drug in the blood because less protein albumin is available for binding than would normally be expected. Alcohol does not compete with phenytoin for binding sites and the drug is not necessarily contraindicated with recent alcohol intake, though alcohol does influence the metabolism of phenytoin. Oral phenytoin would not significantly minimize the risk of adverse effects. • Question 2 1 out of 1 points A patient has been hospitalized for treatment of substance abuse after being arrested and jailed for the past 24 hours. The patient is experiencing severe muscle and abdominal cramps, seizures, and acute psychosis due to abrupt withdrawal. Which of the following drug classes is the most likely cause of these severe and potentially fatal withdrawal symptoms? Response Feedback: Abrupt withdrawal from long-term use of sedative–hypnotic drugs should never be attempted because withdrawal symptoms are serious and potentially fatal. Withdrawal symptoms include agitation, dysphoria, insomnia, vomiting, diarrhea, ataxia, hallucinations, acute psychosis, muscle and abdominal cramps, anorexia, and seizures. These symptoms may occur 12 to 72 hours after the last use of the drug and may last up to 14 days. The abrupt withdrawal of benzodiazepines, opioids, and amphetamines does not cause such severe and potentially fatal withdrawal symptoms. • Question 3 1 out of 1 points A 62-year-old woman has been prescribed a fentanyl transdermal patch for chronic cancer pain. The patient asks the nurse how long it will take for her to experience pain relief. The nurse will instruct the patient that she should feel pain relief in approximately Response Feedback: The nurse will instruct the patient that it will take approximately 24 hours for the full pain-relieving effect of a fentanyl transdermal patch to occur. • Question 4 1 out of 1 points A 4-year-old child is brought to the emergency department by her mother. The mother reports that the child has been vomiting, and the nurse notes that the child's face is flushed and she is diaphoretic. The mother thinks that the child may have swallowed carbachol drops. A diagnosis of cholinergic poisoning is made. Which of the following drugs would be administered? Response Feedback: Acetylcholine and cevimeline are both cholinergic agonists, and, like carbachol, would be contraindicated in this patient. Administration of either of these drugs could be fatal. Nicotine is a direct-acting nicotinic agonist and is not indicated in cholinergic poisoning. Atropine is considered the antidote for cholinergic poisoning. The actions of atropine are a reduction in salivary, bronchial, and sweat gland secretions; mydriasis; cycloplegia; changes in heart rate; contraction of the bladder detrusor muscle and of the gastrointestinal smooth muscle; decreased gastric secretion; and decreased gastrointestinal motility. • Question 5 1 out of 1 points A 59-year-old woman has presented to a clinic requesting a prescription for lorazepam (Ativan) in order to treat her recurrent anxiety. Her care provider, however, believes that a selective serotonin reuptake inhibitor (SSRI) would be more appropriate. What advantage do SSRIs have over benzodiazepines in the treatment of anxiety? Response Feedback: SSRIs are generally well tolerated with few adverse effects. Unlike the benzodiazepines, they do not cause diminished alertness or ataxia. However, they take longer to have a therapeutic effect. Neither class of drug necessitates serial blood testing. SSRIs are normally taken daily. ......CONTINUED [Show More]
