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 24 1 out of 1 points A 30-year-old woman is taking phenelzine (Nardil) 30mg PO tid. The nurse knows that at that dosage, the patient will need to be carefully monitored for Response Feedback: The nurse will closely monitor for the adverse effects of phenelzine related to the anticholinergic effect of the drug, such as dizziness that tends to be more pronounced at dosages above 45 mg/day.

Dizziness is also a sign of a phenelzine drug overdose. Constipation and dry mouth are also adverse effects, not diarrhea and increased secretions. Facial flushing is not an identified adverse effect of phenelzine. Question 25 1 out of 1 points A nurse is providing care for a patient who suffered extensive burns to his extremities during a recent industrial accident. Topical lidocaine gel has been ordered to be applied to the surfaces of all his burns in order to achieve adequate pain control. When considering this order, the nurse should be aware that Response Feedback: Applying lidocaine preparations to severely traumatized mucosa (large skin abrasions, eczema, and burns) can increase its absorption, which in turn increases the risk of systemic toxicity. Intravenous lidocaine is not normally used for analgesia. The destruction of nerve endings in a burn site does not mitigate the need for topical pain control and lidocaine does not need to be potentiated with another anesthetic. Question 26 1 out of 1 points A nurse is caring for a patient who has been admitted with acute cocaine intoxication. Which of the following vital signs would the nurse expect to find initially when assessing the patient? Response Feedback: CNS stimulants like cocaine initially increase heart rate and blood pressure. Cocaine impairs the uptake of norepinephrine and epinephrine by presynaptic nerve endings, thus activating the adrenergic systems and causing hypertension, tachycardia, and vasoconstriction. Question 27 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.

    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.
