A nurse is assessing a client who has heart failure and is taking digoxin. Which of the following findings should the nurse identify as an early indication of medication toxicity?

Choice A Reason:
Identify the client using two identifiers is correct. Prior to administering any medication, especially controlled substances, it's crucial to confirm the client's identity using two unique identifiers, such as their name and date of birth or an identification band and verbal confirmation. Ensuring accurate identification helps prevent medication errors and ensures the right medication is given to the right patient.
Choice B Reason:
Compare the amount of medication available to the inventory record is incorrect. This is part of maintaining accurate documentation and inventory control, ensuring that the amount of medication matches the recorded inventory. However, it typically occurs after confirming the client's identity.
Choice C Reason:
Document the administration of the medication is incorrect. Documentation of medication administration is crucial for legal and medical purposes but should occur after the medication has been safely administered to the correct patient.
Choice D Reason:
Remove the medication from the medication dispensing cabinet is incorrect. Retrieving the medication from the dispensing cabinet is an essential step in the administration process, but it should occur after confirming the client's identity to ensure the right medication is administered to the right individual.

Choice A Reason:
Decreased respiratory rate is incorrect. Heparin administration and an elevated aPTT typically do not directly cause a decrease in respiratory rate. Respiratory rate changes might occur due to other factors such as respiratory conditions, pain, or medications affecting the respiratory center, but they are not commonly linked to heparin therapy.
Choice B Reason:
Increased blood pressure is incorrect. Heparin therapy and an elevated aPTT do not typically result in increased blood pressure. Heparin's primary effect is on preventing blood clotting, and while it can indirectly affect blood pressure by preventing clot formation, it doesn't typically cause a significant increase in blood pressure.
Choice C Reason:
Decreased temperature is incorrect. Heparin therapy and an elevated aPTT do not generally cause a decrease in body temperature. Changes in body temperature might occur due to various reasons such as infection, environmental factors, or certain medications, but they are not directly linked to heparin administration.
Choice D Reason:
Increased pulse rate is correct. An increased pulse rate can be an early indicator of bleeding or a potential side effect of heparin administration. Heparin's anticoagulant effect might predispose individuals to bleeding, so an increased pulse rate could indicate a response to potential bleeding complications rather than a direct effect of heparin itself.
