Exam 12: Basic Principles of Neuropharmacology

A nurse is administering drug X to a patient. The drug information states that the drug acts by activating receptors in the peripheral nervous system by increasing transmitter synthesis. The nurse understands that the effect of this drug is to:

A patient has allergies and takes an antihistamine. The patient wants to know how the drug works. The nurse understands that antihistamines work because they are what?

A patient receives morphine and shows signs of toxicity. The prescriber orders naloxone [Narcan] to reverse the effects of the morphine. The nurse understands that the naloxone reverses morphine toxicity by which action on morphine receptor sites?

A nurse is teaching a group of nursing students about neuropharmacology. Which statement by a student about peripheral nervous system (PNS) drugs indicates a need for further teaching?

A nurse learns about a drug that interferes with transmitter storage in the PNS. The transmitter affected by this drug causes an increased heart rate. What response will the nurse expect to see when this drug is administered?

A nurse is preparing to administer a medication and learns that it is a nonselective agonist drug. What does the nurse understand about this drug?

A nursing student asks about drugs that interfere with the termination of transmitter action. Which statement by the nurse is correct?
