When administering insulin injections, it is crucial to rotate injection sites regularly to prevent the development of lipodystrophy or localized skin changes that can affect insulin absorption. Rotating injection sites every week helps ensure that the same spot is not overused, reducing the risk of skin complications and ensuring consistent insulin absorption. This practice also promotes better insulin absorption and helps to avoid site irritation or pain associated with frequent injections in the same spot. Therefore, the correct answer is D. Options A and B are incorrect because injecting in the same spot or right before meals respectively is not advisable for insulin administration as it can lead to localized skin changes and inconsistent insulin absorption. Option C is also incorrect as rotating injection sites every day may not provide each injection site with enough time to heal properly between injections, potentially leading to skin complications.
