Isosorbide mononitrate modified release formula is structured to provide a nitrate free period. The nurse understands that the rationale for this period is to:

A. "I will remove the tablets from the bottle and keep in a plastic bag in my handbag." This statement is incorrect because nitroglycerin tablets should be kept in their original amber bottle to protect them from light and moisture. Storing them in a plastic bag can compromise their effectiveness.

B. "I will obtain a new prescription every two months so it doesn't expire." While it is important to replace expired medication, nitroglycerin tablets typically have a shelf life of 6 months to 1 year, depending on the formulation. The client should be educated on checking expiration dates rather than just obtaining a new prescription regularly.

C. "I will call 911 if I get chest pain that doesn't go away after taking one tablet." This statement indicates understanding of the importance of seeking emergency help if chest pain persists after taking nitroglycerin, as it may signify a more serious condition requiring immediate medical attention.

D. "I will leave my bottle of nitroglycerin at home in the medicine cabinet." This is inappropriate because nitroglycerin should be easily accessible, ideally kept with the client at all times, especially when they might experience chest pain.

A) Beets: While beets are nutritious and contain some iron, they are not the best source of iron for someone with iron-deficiency anemia. They are more known for their folate content.

B) Seafood: Seafood, particularly shellfish like clams, oysters, and mussels, is an excellent source of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Including seafood in the diet can help improve iron levels.

C) Eggs: Eggs contain some iron, but they also contain substances that can inhibit iron absorption. While they can be part of a balanced diet, they are not the most effective food for increasing iron intake.

D) Bran: Bran is high in fiber and can be beneficial for digestive health, but it contains phytates that can inhibit iron absorption. It is not recommended as a primary source of iron for someone with iron-deficiency anemia.
