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. Wearing an underwire bra between feedings can compress the breasts and potentially lead to mastitis. Nursing bras without underwire are recommended.

B. Covering the breasts immediately after feedings can trap moisture and promote bacterial growth, increasing the risk of mastitis.

C. Cold compresses can help relieve discomfort from engorgement, but applying them before feedings may hinder milk flow and emptying of the breasts, which could increase the risk of mastitis.

D. Ensuring the baby fully empties the breasts with each feeding helps prevent engorgement and decreases the risk of mastitis by promoting effective milk removal.

A. This client's symptom of shortness of breath while ambulating indicates possible worsening heart failure, which requires prompt assessment but is not immediately life-threatening.

B. Vomiting coffee-ground emesis suggests upper gastrointestinal bleeding, which could be

indicative of a serious condition such as a gastrointestinal ulcer or tear and requires immediate assessment to determine the cause and initiate appropriate treatment.

C. While urinary retention in a client with benign prostatic hyperplasia requires attention, it is not as urgent as upper gastrointestinal bleeding.

D. Green drainage from the T-tube in a client who had an open cholecystectomy may indicate bile leakage, which requires assessment and intervention, but upper gastrointestinal bleeding takes precedence due to its potential for rapid deterioration.
