schedule II drugs
37
drugs that are medically useful but with less potential for abuse that lead to moderate or low physical and high psychological dependence. (lesser opioids, stimulants, some barbiturates, miscellaneous depressants, and anabolic steroids) ex: paregoric, butabarbital, and acetaminophen with codeine
schedule III drugs
38
drugs that are medically useful, but with less potential for abuse than scheduled III drugs, their abuse causing limited physical or psychological dependence. (lesser opioids, stimulants that suppress appetite, some barbiturates, benzodiazepines, and miscellaneous depressants) ex: tranquilizers such as chlordiazepoxide (Librium) diazepam (valium) fenfluramine, temazepam, and chloral hydrate
schedule IV drugs
39
drugs with medical use, low potential for abuse, and producing less physical dependence than the schedule IV drugs. (few opiods) ex: mixtures with small amounts of narcotics....cough syrup containing codeine
schedule V drugs
40
the rapidity with which concentration at a target site occurs depends on ?
the blood supply to the site
41
if a pt is taking 2 drugs hat are protein bound, one or the other drug may have a higher concentration in the unbound state than it would if it had been given alone....why?
because the drug with the lower unbound concentration has a greater ability to bind to available protein, leaving less protein to bind to the other drug.
42

deep breathing and coughing
43
Adequate fluid intake of ? mL/kg/day is essential for the pt to eliminate drugs properly
