Quiz 7 323 A nurse is teaching a group of nursing students how the CNS adapts to psychotherapeutic medications. Which statement by a nursing student indicates a need for further teaching? “Adaptation can lead to tolerance of these drugs with prolonged use.” “Adaptation results in an increased sensitivity to side effects over time.” “Adaptation helps explain how physical dependence occurs.” “Adaptation often must occur before therapeutic effects develop.” A group of nursing students asks a nurse to explain the blood-brain barrier. The nurse would be correct to say that the blood-brain barrier: causes infants to be less sensitive to CNS drugs and thus require larger doses. allows only ionized or protein-bound drugs to cross into the central nervous system. prevents lipid-soluble drugs from entering the central nervous system. prevents some potentially toxic substances from crossing into the central nervous system. A patient asks a nurse to explain what drug tolerance means. The nurse responds by telling the patient that when tolerance occurs, it means the patient: will cause an abstinence syndrome if the drug is discontinued abruptly. has developed a psychologic dependence on the drug. will have increased sensitivity to drug side effects. may need increased amounts of the drug over time. Which monoamines act as neurotransmitters in the central nervous system? (Select all that apply.) Acetylcholine Dopamine Serotonin Epinephrine Norepinephrine PreviousNext A nurse provides teaching for a patient who is newly diagnosed with Parkinson’s disease.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    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.
