Jed was born with a congenital heart defect that results in a weak pulse. His mother is constantly

worried about his health. Which of the following is the most sound basis for her concern?
A. The weakened heart may not provide adequate pressure to circulate blood throughout Jed's body.
B. Jed's heart will fail to function properly if he plays hard.
C. Jed's heart doesn't circulate blood through the lungs.
D. The heart provides the body with carbon dioxide, necessary for cell function.

my answer is c.

A. The weakened heart may not provide adequate pressure to circulate blood throughout Jed's body.

The correct answer is A. The weakened heart may not provide adequate pressure to circulate blood throughout Jed's body.

A congenital heart defect can result in a weakened heart that is unable to pump blood effectively. This can lead to inadequate circulation of blood throughout the body, which can cause various health problems and complications. Option A addresses this concern and is the most sound basis for her worry.

Option B suggests that Jed's heart will fail to function properly if he plays hard. While physical exertion can be challenging for someone with a weak heart, it does not necessarily mean that the heart will fail completely. This option does not address the daily concerns about Jed's overall health.

Option C is not an accurate representation of a congenital heart defect. In most cases, the heart still circulates blood through the lungs, but it may do so with reduced efficiency or abnormalities.

Option D is unrelated to the concerns about Jed's heart defect. The heart's primary function is to pump oxygenated blood to the body, not to provide carbon dioxide.

To determine the most sound basis for the mother's concern, let's analyze each option and see which one is the most appropriate:

A. The weakened heart may not provide adequate pressure to circulate blood throughout Jed's body.
This option highlights a valid concern. With a weakened heart, there is a possibility that it may not generate enough force or pressure to effectively pump blood throughout Jed's body, which can have significant implications for his overall health.

B. Jed's heart will fail to function properly if he plays hard.
While physical exertion can indeed affect the functioning of the heart, this option only focuses on the impact of strenuous activities. It does not necessarily address the constant concern the mother has about Jed's overall health. Therefore, it may not be the most sound basis for her worry.

C. Jed's heart doesn't circulate blood through the lungs.
This option is incorrect. In a healthy cardiovascular system, the heart is responsible for pumping oxygenated blood to various parts of the body, including the lungs, where carbon dioxide is exchanged for oxygen.

D. The heart provides the body with carbon dioxide, necessary for cell function.
This option is also incorrect. The heart's primary role is to circulate blood, delivering oxygen and nutrients to the body's cells, not carbon dioxide. Moreover, excess carbon dioxide is a waste product that is eliminated through the respiratory system.

Considering the analysis, option A seems to be the most sound basis for the mother's concern. Jed's weak pulse, resulting from his congenital heart defect, may indeed raise concerns about the heart's ability to adequately circulate blood throughout his body.
