Nutrition
1a- You are working w/a patient who is being discharged from the acute care unit after a heart attack (myocardial infarction). The patient's primary care provider has prescribed medical nutrition therapy, w/a diet that is low in sodium & saturated fat. The patient comes from family where food plays an important role in traditional culture practices.
a. What do you need to know about the patient & the family to assist in dietary planning?
To assist this patient & the family w/dietary planning, it is important to find out the following information:
* Who prepares the food in the home?
* Who buys the food and where is the food purchased?
* What foods are regularly eaten? Are there special foods for the holidays or family occasions?
* What are the patient's food preferences?
In addition, the patient should keep a record of dietary intake (usually recorded for 3 to 7 days).
1b- You are working w/a patient who is being discharged from the acute care unit after a heart attack (myocardial infarction). The patient's primary care provider has prescribed medical nutrition therapy, w/a diet that is low in sodium & saturated fat. The patient comes from family where food plays an important role in traditional culture practices.
b. How can you assist this patient to meet the prescribed dietary requirements?
Teaching about foods that are high in sodium & saturated fat is an important part of the plan for this patient. Reading labels & menus (if patient eats out) will help in the selection of appropriate foods. The pat. & family also may be informed about the possible substitutions for foods, spices, and oils that are high sodium & fat. Alternatives, such as polyunsaturated oils, lean meats & egg substitutes, may be incorporated into meal preparation. A separate meal plan for the patient is usually not necessary because flavorings, such as lemon, can make foods attractive (as well as healthy) for the entire family.
