Question 1 of 5

The health care provider has changed a client's prescription from the PO to the IV route of administration. The nurse should anticipate which change in the pharmacokinetic properties of the medication?

A. The client will experience increased tolerance to the drug's effects and may need a higher dose. B. The onset of action of the drug will occur more rapidly, resulting in a more rapid effect. C. The medication will be more highly protein-bound, increasing the duration of action. D. The therapeutic index will be increased, placing the client at greater risk for toxicity.

Correct Answer: B

Rationale: When changing the route of administration from PO to IV, the absorption process is bypassed, leading to a more rapid onset of action of the medication and consequently a quicker effect.

Choices A, C, and D are incorrect. Increased drug tolerance and higher doses are not typical outcomes of changing the route of administration. Protein binding does not increase with a change to IV administration; rather, it is the bioavailability and onset of action that are affected. Moreover, an increased therapeutic index reduces the risk of drug toxicity, contrary to what is stated in choice D.
