A nurse is reviewing a client's health record and notes that the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-

i,- i,- i,- i,- i,- i,- i,- i,-



previous medication. The nurse should recognize that the

movement disorders that can be caused by a number of central
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



nervous system medications, such as typical antipsychotic

medications)


A nurse is caring for a client who is taking oral Oxycodone The

client states he is also taking Ibuprofen in three recommended
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-

,doses daily. The nurse should identify that an interaction between
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



these two medications will cause which of the following findings?
i,- i,- i,- i,- i,- i,- i,- i,- i,-




A. A decrease in serum levels of ibuprofen, possibly leading to a
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



need for increased doses of this medication
i,- i,- i,- i,- i,- i,-




B. A decrease in serum levels of oxycodone, possibly leading to a
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



need for increased doses of this medication
i,- i,- i,- i,- i,- i,-




C. An increase in the expected therapeutic effect of both

medications
D. An increase in expected adverse effects for both medications
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-i,-



C. An increase in the expected therapeutic effect of both
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



medications


(These medications work together to increase the pain-relieving
i,- i,- i,- i,- i,- i,- i,- i,-



effects of both medications. Oxycodone is a narcotic analgesic,
i,- i,- i,- i,- i,- i,- i,- i,- i,-



and ibuprofen is an NSAID. They work by different mechanisms,
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



but pain is better relieved when they are taken together)

infant. Which of the following pharmacokinetic principles should
i,- i,- i,- i,- i,- i,- i,- i,-



the nurse consider when administering medications to this client?

(Select all that apply.) i,- i,- i,-

C. Infants' blood-brain barrier is poorly developed.
i,- i,- i,- i,- i,- i,-




D. Infants have an increased ability to absorb topical medications.
i,- i,- i,- i,- i,- i,- i,- i,- i,-




E. Infants have an increased number of protein-binding sites.
i,- i,- i,- i,- i,- i,- i,- i,- i,-i,- i,-



B. Infants have immature liver function.

C. Infants' blood-brain barrier is poorly developed.
i,- i,- i,- i,- i,- i,-




D. Infants have an increased ability to absorb topical medications.
i,- i,- i,- i,- i,- i,- i,- i,- i,-




(B. Infants have immature liver function until 1 year of age. The

i,- i,- i,- i,- i,- i,- i,- i,-



smaller dosages. i,-




C. Infants have a poorly developed blood-brain barrier, which
i,- i,- i,- i,- i,- i,- i,- i,- i,-



places them at risk for adverse effects from medications that pass

through the blood-brain barrier. The nurse should administer

D. Because infants have more blood flowing to the skin and their
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



skin is thin, their medication absorption is increased, making

them prone to toxicity from topical medications)
