    Metoprolol [Lopressor, Betaloc] is a drug that is a selective antagonist for beta1-adrenergic receptors. When stimulated, beta1- receptors of the heart increase the heart rate. The nurse should assess the patient receiving metoprolol for excessive response, which would be seen as

    The nurse is teaching a patient who has been prescribed terbinafine HCl [Lamisil] tablets 250mg once a day for 12 weeks for toenail onychomycosis. Because the drug can be hepatotoxic, the nurse teaches the patient to report (SATA)

    A terminal cancer patient has been receiving narcotic analgesics for severe pain for more than 6 months. The prescriber has increased the dose of the long-acting opiate and added and "as needed" opiate for breakthrough pain. The nurse should
    a. recognize that the higher dose is needed because the patient would have undergone down-regulation of opiate receptors.
    b. recoginze that the additional medcation is needed because cancer causes an up-regulation of opiate receptors.
    c. question the higher dose of medication because the patient is at risk for narcotic addiction.
    d. question why the medication is being prescribed on a regular and an as needed basis.
  15. 8-5
    The difference between pharmacodynamic and metabolic (pharmacokinetic) tolerance is that there is a decreased response to the drug in tolerance and

    Warfin sodium (Coumadin) is a drug that slows the formation of clots. It is highly protein bound. Only the unbound fraction of the drug is active. If the nurse is administering warafin to a malnourished patient with a serum protein level of 4.9 gm/dL, the nurse would expect the patient's response to the drug to be

  18. 11-1
    Which statements about older adults and pharmacotherapy are generally true? (SATA)
    a. the goal of therapy for the older adult is to cure the disease
    b. there is a wider individual variation in drug response in the older adult
    c. Older adults are less sensitive to drugs
    d. Older adults absorb less of the dose of medication than younger individuals
    e. absorption of many drugs slows with aging
    f. changes in body fat and lean body mass that occur with aging can cause lipid-soluble drugs to decrease in effect and water-soluble drugs to have a more intense effect
    g. liver enzyme activity may be increased in the older adult
    h. drug accumulation secondary to decreased renal excretion is the most common cause of adverse reactions in older adults
    i. a reduction in the number of receptors and/ordecreased affinity for receptors in the older adult may decrease the response to drugs that work by receptor interaction

    b. inadequate action of the drugs
