Nursing Elites

1. During early tooth development, vitamin A deficiency leads to enamel hypoplasia and defective dentin formation. Because of its effect on soft tissues and bone, vitamin A contributes to normal spacing of teeth.

• A. Both statements are true.
• B. Both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: A

Rationale: Both statements are true. The effect of vitamin A on the growth of soft tissues and bones naturally extends to the teeth and surrounding structures. Enamel hypoplasia, involving defective enamel matrix and incomplete calcification of enamel and dentin, can be due to vitamin A deficiency. The effect of this vitamin upon surrounding bone directly affects spacing patterns of the teeth within the bone and dentition. Choice A is correct because both statements accurately describe the influence of vitamin A on tooth development. Choices B, C, and D are incorrect as they do not reflect the accuracy of the statements provided.

2. Which nutrient deficiency are people who regularly take prescription drugs such as steroids and diuretics at risk for?

• A. Potassium
• B. Selenium
• C. Iodine
• D. Chloride

Correct answer: A

Rationale: Regular intake of prescription drugs like steroids and diuretics can lead to the loss of potassium in the body, causing a condition known as hypokalemia. Therefore, people on these medications require careful monitoring and often need potassium supplementation to prevent this deficiency. The other options, selenium, iodine, and chloride, are incorrect because there is no specific link between their deficiency and the regular use of steroids and diuretics.

3. What activities best describe the work of the placenta during pregnancy?

• A. surrounding and cushioning the fetus
• B. combining maternal and fetal blood stores to exchange nutrients
• C. producing hormones that maintain the pregnancy
• D. absorbing vitamins and minerals that can be transferred to the fetus

Correct answer: C

Rationale: The placenta plays a crucial role in producing hormones that are necessary for maintaining pregnancy, supporting fetal development, and preparing the mother's body for childbirth. Choices A, B, and D are incorrect because the placenta's primary function is not to surround and cushion the fetus, combine blood stores for nutrient exchange, or absorb vitamins and minerals. While the placenta does facilitate the exchange of nutrients and oxygen between the mother and fetus, its hormone production is the most critical function during pregnancy.

4. A client is following Seventh-Day Adventist dietary laws. Which of the following dietary guidelines should the nurse include in the plan of care?

• A. Replace salt with pepper when seasoning food.
• B. Request that coffee is removed from meal trays.
• C. Offer pork with two meals per week.
• D. Provide a high-protein snack between meals.

Correct answer: B

Rationale: Seventh-Day Adventists typically avoid stimulants like caffeine, so requesting that coffee be removed from meal trays is appropriate. Choice A is incorrect because it does not specifically relate to Seventh-Day Adventist dietary guidelines. Choice C is incorrect as pork is generally avoided in Seventh-Day Adventist dietary laws. Choice D is incorrect as it does not address the specific dietary preferences of Seventh-Day Adventist clients.

5. A client who is 2 days postoperative following abdominal surgery is about to progress from a clear liquid diet to full liquids. Which of the following items should the nurse tell the client he may now request to have on his meal tray?

• A. Cranberry juice
• B. Flavored gelatin
• C. Skim milk
• D. Chicken broth

Correct answer: A

Rationale: Cranberry juice is an appropriate choice for a client transitioning from a clear liquid diet to full liquids post abdominal surgery. It provides hydration and some essential nutrients. Flavored gelatin is usually allowed on a clear liquid diet and may not be suitable for a full liquids phase. Skim milk and chicken broth are typically introduced in a later stage of the diet progression, closer to a soft diet, due to their higher protein and fat content.
