1. Which type of immunity is demonstrated by the transfer of a mother's immunoglobulin across the placenta to protect the child?

• A. Natural active immunity
• B. Natural passive immunity
• C. Artificial active immunity
• D. Artificial passive immunity

Correct answer: B

Rationale: The immunoglobulin passed from the mother to the child through the placenta is an example of natural passive immunity, making choice B the correct answer. This transfer gives the child temporary immunity to various diseases without their immune system having to work. On the other hand, natural active immunity (Choice A) occurs when the body produces its own antibodies in response to an antigen. Artificial active immunity (Choice C) is achieved through vaccinations, where the immune system is stimulated to produce antibodies against a specific disease. Artificial passive immunity (Choice D) is a temporary immunity that involves the transfer of pre-formed antibodies from another source.

2. A pregnant woman has applied to use WIC services to supplement her food intake. The WIC program would provide vouchers for _____ in this situation.

• A. lean beef
• B. fruit-flavored yogurt
• C. whole grain bread
• D. refried beans

Correct answer: C

Rationale: The correct answer is C: whole grain bread. The WIC program aims to provide nutritious foods to support a healthy diet during pregnancy. Whole grain bread is a good source of fiber and essential nutrients. Choice A, lean beef, is a protein source but may not be as versatile as whole grain bread in providing a variety of nutrients essential during pregnancy. Choice B, fruit-flavored yogurt, may contain added sugars and may not offer the same level of essential nutrients as whole grain bread. Choice D, refried beans, is a good source of protein and fiber, but whole grain bread is often a staple recommended in pregnancy for its nutritional benefits.

3. A client taking antibiotics develops diarrhea. Which of the following foods should the nurse recommend to include in the client’s diet?

• A. Whole wheat bread
• B. Fresh orange sections
• C. Ice cream
• D. Yogurt

Correct answer: D

Rationale: Yogurt is the correct answer because it contains probiotics that can help restore normal gut flora and reduce antibiotic-associated diarrhea. Whole wheat bread (Choice A) may worsen diarrhea due to its high fiber content. Fresh orange sections (Choice B) are acidic and may irritate the digestive system further. Ice cream (Choice C) is high in sugar and fat, which can exacerbate diarrhea.

4. What is the term for a barrier that prevents the normal emptying of stomach contents into the duodenum?

• A. Dumping syndrome
• B. Gastritis
• C. Gastric outlet obstruction
• D. Hypochlorhydria

Correct answer: C

Rationale: Gastric outlet obstruction refers to a condition where the opening between the stomach and the duodenum is blocked, preventing the normal passage of food. This is why choice 'C' is correct. 'A: Dumping syndrome' is incorrect because it is a condition where stomach contents move too quickly through the small intestine, not a barrier preventing emptying. 'B: Gastritis' is inflammation of the stomach lining, not a blockage of the outlet. 'D: Hypochlorhydria' refers to low stomach acid, which may affect digestion but does not create a physical barrier blocking the outlet of the stomach.

5. 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.
