1. Which mineral is a principal component of cell membranes?

• A. phosphorus
• B. magnesium
• C. iron
• D. iodine

Correct answer: A

Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.

2. Which foods should be avoided on a low-potassium diet? (SATA)

• A. Bananas
• B. A, C
• C. Sweet potatoes
• D. Frozen corn

Correct answer: B

Rationale: Bananas, sweet potatoes, and orange juice are high in potassium.

3. Which organ absorbs water and vitamin K and may be affected by ulcerative colitis?

• A. Stomach
• B. Pancreas
• C. Large intestine
• D. Small intestine

Correct answer: C

Rationale: The large intestine is the organ that is primarily responsible for the absorption of water and vitamin K in the human body. A disease like ulcerative colitis can disrupt these functions by causing inflammation and ulcers in the lining of the large intestine, leading to digestive issues. The stomach (Choice A) primarily functions to break down and digest food, not to absorb water and vitamins. The pancreas (Choice B) secretes enzymes to aid in digestion and hormones to regulate blood sugar, but does not absorb water and vitamins. The small intestine (Choice D) is primarily responsible for absorbing nutrients from digested food, but not specifically water and vitamin K. Therefore, these other choices are incorrect.

• B. An obese client needs to gain as much weight as a client with a normal body mass index.
• C. A client with a normal body mass index should plan on gaining 50 pounds.
• D. Clients will need to eat for two when they are pregnant.

Correct answer: A

Rationale: Appropriate weight gain is crucial for reducing the risk of preterm birth.

• A. Knee chest position
