Final answer:
The nurse should recommend Soy milk to the client with lactose intolerance since it does not contain lactose and is safe for those unable to digest this sugar.
Step-by-step explanation:
Lactose intolerance is a condition that poses dietary challenges for many individuals. The inability to digest lactose, which is a sugar found in milk and other dairy products, requires those affected to seek lactose-free foods. Among the options provided, B: Soy milk is the correct recommendation a nurse should make to a client with lactose intolerance. Soy milk is a plant-based milk alternative that does not contain lactose, making it a safe choice for those with this condition. On the other hand, sour cream, ice cream, and plain yogurt generally contain lactose and might cause discomfort and symptoms such as bloating, cramps, and nausea. It is worth mentioning that some yogurts contain live and active cultures that can help digest lactose; however, for a lactose-intolerant individual, it is still safer to opt for lactose-free versions or plant-based alternatives.
