● ● ● ● ● ● Respo nse Feedb ack: ● Neuroleptic malignant syndrome is characterized by fever, sweating, tachycardia, muscle rigidity, tremor, incontinence, stupor, leukocytosis, elevated creatinine phosphokinase levels, and renal failure. Agitation, pruritis, thirst, and increased urine output are not indicative of ● ● ●
neuroleptic malignant syndrome. ● ● Question 25 ● 1 out of 1 points ● ● ● ● A patient with mild low back pain has been advised to take acetaminophen. The nurse will inform him that excessive intake of acetaminophen may result in ● ● ● ● ● ● Respo nse Feedb ack: ● A patient taking acetaminophen should be taught the common adverse effects of the drug, which include rash, urticaria, and nausea. Nausea, not gastrointestinal distress, is a common adverse effect of acetaminophen. Flushing, dizziness, and feelings of tingling, heat, and fatigue are the most common adverse effects of sumatriptan, not acetaminophen. ● ● ● ● ● Question 26 ● 1 out of 1 points
● ● ● ● A patient has a history of tonic-clonic seizures that have been successfully treated with phenytoin (Dilantin) for several years. Phenytoin achieves a therapeutic effect by ● ● ● ● ● ● Respo nse Feedb ack: ● Phenytoin reversibly binds to sodium channels while they are in the inactive state. This binding delays the return of the channel to an active state. Because sodium can enter the cell to initiate an action potential only when the channels are active, the time between action potentials is greatly lengthened, the neurons cannot fire at an excessive rate, and excessive muscle contractions that occur in grand mal-type seizures are prevented. Phenytoin does not directly affect the function of calcium channels or levels of GABA and glutamate. ● ● ● ● ● Question 27 ● 1 out of 1 points ● ● ● ● The wife of a patient who is taking haloperidol calls the clinic and reports that her husband has taken the first dose of the drug and it is not having a therapeutic effect. An appropriate ● ● ●
response by the nurse would be ● ● ● Respo nse Feedb ack: ● The nurse should instruct the wife to continue offering her husband the drug and that it will probably take several days to reach its full therapeutic effect. The dosage would not be increased, decreased, or discontinued. ● ● ● ● ● Question 28 ● 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 ● ● ● ● ● ● Respo nse Feedb ack: ● 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 ● ● ●
