Through which structure does blood flow from the heart to the lungs in the pulmonary circulation?

Left ventricle

Pulmonary artery

Left atrium

Pulmonary veins

Answer and Explanation

The Correct Answer is B

Choice A reason: The left ventricle pumps oxygenated blood into the aorta and then to the rest of the body, not

directly to the lungs.

Choice B reason: The pulmonary artery is the correct answer because it carries deoxygenated blood from the right

ventricle of the heart to the lungs for oxygenation.

Choice C reason: The left atrium receives oxygenated blood from the lungs through the pulmonary veins, so it is not

involved in sending blood to the lungs.

Choice D reason: The pulmonary veins carry oxygenated blood from the lungs to the left atrium, not from the heart

to the lungs.

Correct Answer is A

Explanation

Choice A reason: Caffeinated beverages can cause diarrhea as caffeine stimulates the gastrointestinal tract and can

lead to increased bowel movements.

Choice B reason: Ripe bananas are typically recommended to manage diarrhea due to their pectin content, which can help absorb liquid in the intestines.

Choice C reason: White rice is often recommended for those with diarrhea as it is easy to digest and can help form

stools.

Choice D reason: Low fiber cereal is less likely to cause diarrhea compared to high fiber options, as fiber can accelerate the passage of food through the intestines.

A. Eat granola for breakfast. B. Avoid using salt substitutes when cooking. C. Replace sugar with molasses when baking. D. Choose orange juice instead of apple juice.

Correct Answer is B

Explanation

Choice A reason: Granola may contain ingredients like nuts and dried fruits that are high in potassium, which is not
suitable for a low potassium diet.

Choice B reason: Many salt substitutes contain potassium chloride instead of sodium chloride, and using them can increase potassium intake, which is not recommended for a client on a low potassium diet.

Choice C reason: Molasses is high in potassium, so replacing sugar with molasses when baking would not be
appropriate for someone on a low potassium diet.

Choice D reason: Orange juice is high in potassium compared to apple juice, making it an unsuitable choice for
someone on a low potassium diet.
