Results Displayed Feedback Question 1 1 out of 1 points A nurse who provides care on an acute medicine unit has frequently recommended the use of nicotine replacement gum for patients who express a willingness to quit smoking during their admission or following their discharge. For which of the following patients would nicotine gum be contraindicated? Response Feedback: Nicotine in any dosage form should not be used in patients immediately after myocardial infarction, or in those with life- threatening arrhythmias or severe or worsening angina pectoris. Antibiotics, anticoagulants, and renal failure are not contraindications for the use of nicotine as an aid to smoking cessation. Question 2 1 out of 1 points A 64-year-old-patient has been prescribed lorazepam (Ativan) because of increasing periods of anxiety.

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 4 0 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.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
