Question 1 1 out of 1 points A 39-year-old patient who is having trouble sleeping is beginning drug treatment with zaleplon (Sonata). The nurse will be sure to ask the patient if she is taking Response Feedback: The nurse will assess for cimetidine use. Cimetidine greatly increases the level of circulating zaleplon and could cause toxic effects in the patient. Secobarbital is a barbiturate, and oxycodone and meperidine are narcotics that would not be used with lorazepam because the combinations may depress respiratory drive, create severe hypotension or bradycardia, and substantially alter level of consciousness. Question 2 1 out of 1 points A nurse is talking to an 18-year-old patient who has had a seizure disorder since she was 10 years old and is taking phenytoin (Dilantin). The nurse should suggest that she take which of the following? Response Feedback: Long-term phenytoin therapy is associated with folate deficiency. Folic acid and phenytoin are structurally similar and thought to compete with each other for the same receptors. A deficiency in folic acid in a pregnant woman can cause birth defects. Potassium, iron, and vitamin C do not compete with phenytoin nor are they directly affected by phenytoin. Question 3 1 out of 1 points A 26-year-old professional began using cocaine recreationally several months ago and has begun using the drug on a daily basis over the past few weeks. He has noticed that he now needs to take larger doses of cocaine in order to enjoy the same high that he used to experience when he first used the drug. A nurse should recognize that this pattern exemplifies Response Feedback: With drug use over time, tolerance develops. Tolerance occurs when the body develops a natural resistance to the drug's physical or euphoric effects, making it necessary to take increasing doses more frequently to achieve the desired effect. Question 4 1 out of 1 points
A patient has been admitted to the ICU because of multiple traumas due to a motor vehicle accident. The physician has ordered propofol (Diprivan) to be used for maintenance of sedation. Before administration of propofol, a priority assessment by the nurse would be to check for a history of Response Feedback: Propofol is relatively contraindicated in patients with a history of seizure disorders because they are at risk of developing convulsions during the recovery phase. This drug should be used with caution in patients with low blood pressure because it can aggravate this condition. Also, it should be used with caution in patients with increased intraocular pressure because it can cause a substantial reduction in cerebral perfusion. Because disorders of lipid metabolism can be aggravated by the emulsion vehicle in which propofol is delivered, it should be used with caution in patients with diabetic hyperlipidemia.
