Question 6 1 out of 1 points Which of the following drugs used to treat anxiety would be appropriate for a patient who is a school teacher and is concerned about feeling sedated at work? Response Feedback: Buspirone does not cause as much sedation and functional impairment as lorazepam, alprazolam, and diazepam. However, it can cause dizziness, nausea, headache, nervousness, lightheadedness, or excitement. Question 7 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 Response Feedback : 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 8 1 out of 1 points A nurse will be prepared to administer naloxone (Narcan) to a patient who has had an overdose of morphine. Repeated doses of Narcan will be necessary because Narcan

Response Feedback : The duration of the morphine may be longer than the duration of naloxone. Therefore, naloxone has a shorter half-life than morphine. Repeated doses may be necessary to maintain reversal of the opiate's effects. Naloxone does not increase the action of morphine, and it causes the respiratory rate to increase, not decrease. Dosage strength is not associated with drug duration. Question 9 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 Response Feedback : 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 10 1 out of 1 points Which of the following would be an expected outcome in a patient who has been given atropine during a medical emergency? Response Feedback : Atropine is used to help restore normal sinus rhythm in emergency situations, such as symptomatic bradycardia, pulseless electrical activity, ventricular asystole, or cardiopulmonary resuscitation. It does not resolve acid-based imbalances or decreased level of consciousness and atropine increases, rather than decreases, blood pressure. Question 11 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 Response Feedback: 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
