Final answer:
The correct option is b.
Cottage cheese is the best protein source recommended for a lactating client, providing high-quality protein along with other essential nutrients.
Other viable options include legumes and whole grain cereals, but they may not offer the same concentration and quality of protein as cottage cheese does.
Step-by-step explanation:
The nurse should recommend cottage cheese as the best source of protein for a client who is lactating to increase their protein intake. Cottage cheese provides a high concentration of protein along with important nutrients such as calcium, vitamin B2 (riboflavin), and vitamins A and D which are beneficial during lactation.
Legumes, peanut butter, and whole grain cereals also offer protein, but cottage cheese stands out as it contains high-quality, easily digestible protein essential for the health of both mother and infant.
Other excellent sources of protein include legumes like soybeans, lentils, and beans, and whole grains such as quinoa and buckwheat.
A balanced diet with a variety of protein sources is important to improve nutrient intake and promote health benefits. When consuming meat, choosing lean cuts and preparing them with little to no added saturated fat is advisable.
