Final answer:
Broccoli is a suitable non-dairy calcium source for a lactose-intolerant client and can be safely included in their diet to maintain adequate calcium levels during pregnancy.
Step-by-step explanation:
During a first prenatal visit, a lactose intolerant client should be advised of alternative calcium sources other than lactose-containing products such as milk, cheese, and yogurt. Since lactose intolerance requires avoiding these common dairy products that are high in calcium, it is important to find non-dairy sources of calcium.
Broccoli is an excellent source of calcium that can be recommended for lactose-intolerant individuals. Other non-dairy sources include green leafy vegetables, almonds, fortified soy or rice beverages, and fish with soft bones like sardines. These alternatives provide necessary calcium for bone health and overall well-being during pregnancy without causing the discomfort associated with lactose intolerance.
