that has a narrow therapeutic range. The nurse administering this medication will expect to do
what? - CORRECT ANSWER-c. Monitor plasma drug levels.

intravenous gentamicin. A serum drug test reveals toxic levels. The dosing is correct, and this
medication has been tolerated by this patient in the past. Which could be a probable cause of
the test result? - CORRECT ANSWER-c. The patient is taking another medication that binds to
serum albumin.

becoming "immune" to a medication because it no longer works to alleviate symptoms. The
nurse recognizes that this decreased effectiveness is likely caused by: - CORRECT ANSWER-c.
Desensitization of receptor sites by continual exposure to the drug.
, Ch 4 Pharmacokinetics, Pharmacodynamics, and Drug Interactions 32. A patient who is taking
morphine for pain asks the nurse how a pain medication can also cause constipation. What does
the nurse know about morphine? - CORRECT ANSWER-d. It is selective to receptors that
regulate more than one body process.

administering morning medications. The nurse gives a patient multiple medications, two of
which compete for plasma albumin receptor sites. As a result of this concurrent administration,
the nurse can anticipate that what might occur? - CORRECT ANSWER-a. Binding of one or both
agents will be reduced.
b. Plasma levels of free drug will rise.
d. The increase in free drug will intensify effects.
Ch 4 Pharmacokinetics, Pharmacodynamics, and Drug Interactions 34. When administering
medications to infants, it is important to remember which of the following? - CORRECT
ANSWER-b. Immaturity of renal function in infancy causes infants to excrete drugs less
efficiently. <br> c. Infants have immature livers, which slows drug metabolism. <br> d. Infants
are more sensitive to medications that act on the central nervous system (CNS).
