A nurse is preparing to administer vancomycin to a client who has an infected wound. The nurse should plan to monitor for which of the following adverse reactions?

A. Mixing ferrous sulfate capsules with food may alter the absorption of the medication. It is generally recommended to take iron supplements on an empty stomach for better absorption, unless gastrointestinal side effects occur, in which case taking it with food can help reduce

irritation.

B. Dissolving ferrous sulfate capsules in chocolate milk or any other liquid may affect the taste and consistency of the drink. Additionally, chocolate milk may contain substances that could

interfere with iron absorption.

C. Administering iron supplements with a glass of orange juice is a common recommendation because vitamin C enhances the absorption of iron. This combination helps improve the bioavailability of the iron supplement.

D. There is no specific indication to administer ferrous sulfate capsules at bedtime. It is typically recommended to take iron supplements on an empty stomach for better absorption, unless gastrointestinal side effects occur, in which case taking it with food can help reduce irritation.

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.
