A nurse is caring for a client who is taking levothyroxine. Which of the following findings should indicate to the nurse that the medication is effective?

A.

A. Auscultating the client's left arm for a bruit helps assess the patency and function of the arteriovenous fistula. A bruit indicates normal blood flow through the fistula.

B. Comparing blood pressure in both arms every 2 hours is not specifically related to monitoring the arteriovenous fistula. Blood pressure comparison may be done periodically but is not as directly relevant to postoperative care of the fistula.

C. Instructing the client to keep the left arm in a dependent position may help with venous return but is not the primary action for monitoring the arteriovenous fistula's patency and function.

D. Encouraging the client to restrict movement of the left arm is not necessary unless there are specific instructions from the surgeon. Encouraging gentle movement and range of motion exercises may actually be beneficial for preventing stiffness and promoting healing.

A.

A. It's important to include the complete name of the medication to ensure clarity and accuracy in documentation.

B. Omitting the leading zero before a decimal point can lead to medication errors, so it's important to include it.

C. "U" is commonly used to denote units when documenting insulin dosage, so this statement is accurate.

D. "QOD" is an outdated abbreviation and can lead to confusion, so it should not be used; instead, "every other day" should be written out for clarity.
