Final answer:
During the first trimester of pregnancy, a slight weight gain is common, and caloric intake does not need to increase. However, none of the client's statements regarding physiological changes during pregnancy at 10 weeks are accurate.
Step-by-step explanation:
The physiological changes that occur during pregnancy for a client at 10 weeks of gestation with a normal BMI include a number of different adaptions within the body. One such aspect of these changes involves weight gain. During the first trimester, it is not necessary for the pregnant person to consume additional calories to maintain a healthy pregnancy, although a weight gain of approximately 0.45 kg (1 lb) per month is common. As the pregnancy progresses to the second and third trimesters, increased appetite may lead to a higher caloric intake, but only an additional 300 calories per day are needed to support the growing fetus. Pregnant people typically gain about 0.45 kg (1 lb) per week during these later stages.
Regarding the client's understanding of these changes, the statement 'My blood pressure will remain the same throughout pregnancy.' is not accurate, as blood pressure can fluctuate during pregnancy. Furthermore, 'I should expect my heart rate to decrease.' is not correct since heart rate typically increases during pregnancy to accommodate the increased blood volume, which rises by 30 percent. The statement 'I will need to decrease my caloric intake.' is also incorrect, as caloric needs may increase slightly, particularly during the second and third trimesters. Lastly, 'Weight gain is not a concern during the first trimester.' is misleading. Even though excessive weight gain is not typically expected in the first trimester, some weight gain is indeed common and expected.
Therefore, none of the client's statements indicate an accurate understanding of the physiological changes during pregnancy.
