most critical nursing consideration?
Closely monitor the patient’s drug levels and clinical response to avoid toxicity.
2. A patient presents with a new prescription for an oral anticoagulant. What important point
should the nurse emphasize regarding the pharmacokinetics of this medication?
Inform the patient about the delayed onset of action, which can take several days to
achieve therapeutic levels.
3. A nurse is teaching a patient about the importance of compliance with prescribed medication
regimens. What is the most significant factor influencing adherence to pharmacotherapy?
Understanding the purpose and potential side effects of the medication can significantly
enhance adherence.

increased heart rate.
7. A nurse is reviewing a patient’s medication list and notes the use of a medication that acts as
an enzyme inhibitor. What is a key potential effect of this type of medication?
Increased levels of co-administered medications that are metabolized by the same enzyme,
leading to possible toxicity.

Dry mouth, constipation, blurred vision, and urinary retention due to decreased secretions
and motility.
