Final answer:
Nurses should focus on teaching clients with Crohn's disease about meeting nutritional needs to prevent malnutrition and manage symptoms, which is crucial due to issues with nutrient absorption.
Step-by-step explanation:
A client is admitted to the hospital with a diagnosis of Crohn disease. It is important for the nurse to include dietary modifications that aid in meeting nutritional needs as part of the teaching plan for the client. Since Crohn's disease can lead to malnutrition due to faulty absorption of nutrients, ensuring proper nutrition is vital. Educating the client on the types of food that may be easier to digest and less likely to cause flare-ups is essential. This includes advising on a balanced diet, possibly rich in necessary vitamins and minerals, and possibly the use of supplements as needed. While controlling constipation may also be important, it is specific to individual needs and symptoms. The goal of preventing increased weakness is directly tied to meeting nutritional needs, and thus is already embedded in that focus. Anticipating a sexual alteration is less immediately relevant to the acute teaching needs upon diagnosis and hospital admission.
