Final answer:
The client shows understanding by stating that they need to gain weight during pregnancy, as it is recommended to consume an additional 300 calories per day during the second and third trimesters and to expect a weight gain of around 0.45 kg (1 lb) per week.
Step-by-step explanation:
The correct statement that the client who has a BMI of 22 and is learning about dietary recommendations during pregnancy can make to indicate understanding is: 'I need to gain weight during pregnancy.' This reflects the fact that during the second and third trimesters, a pregnant person should consume an additional 300 calories per day and can expect to gain approximately 0.45 kg (1 lb) per week. It is a myth that a pregnant woman needs to double her pre-pregnancy caloric intake; instead, a balanced diet that includes a variety of nutrients and foods within an appropriate calorie level is recommended. Seafood can be included as it is a source of protein, but it should be low in mercury. Regular exercise can be continued unless advised otherwise by a healthcare provider. Protein intake should not be limited to prevent gestational diabetes; instead, a diet with an appropriate amount of protein is crucial during pregnancy.
