ATI Nutrition Practice A

1. Which of the following is a good food source of iodine?

A. Seafood
B. Lettuce
C. Broccoli
D. Pork

Correct answer: A

Rationale: Seafood is a rich source of iodine, essential for maintaining healthy thyroid function and overall metabolic health. While lettuce, broccoli, and pork may contain some iodine, they do not provide as substantial an amount as seafood. Therefore, they are not considered 'good' sources of iodine in comparison.

2. Which of the following statements are true about iron?

A. The iron needs of vegans are 20% higher, and the needs of endurance athletes are 10% lower.
B. It is one of the most common nutrient deficiencies in the world.
C. Its absorption is increased by Vitamin C and during pregnancy.
D. Its absorption is increased by tannic acid and calcium in milk.

Correct answer: C

Rationale: Choice C is correct because iron absorption is indeed increased by Vitamin C and during pregnancy. The other choices are incorrect. Choice A is wrong as there are no universally accepted percentages for the iron needs of vegans and endurance athletes. Choice B is inaccurate as iron deficiency is actually one of the most common nutritional deficiencies worldwide. Choice D is incorrect because tannic acid and calcium in milk actually inhibit iron absorption rather than increasing it.

3. What is the purpose of the cuff in a Tracheostomy tube?

A. Separate the upper and lower airway
B. Separate trachea from the esophagus
C. Separate the larynx from the nasopharynx
D. Secure the placement of the tube

Correct answer: B

Rationale: The purpose of the cuff in a Tracheostomy tube is to separate the trachea from the esophagus. The cuff helps prevent aspiration by creating a seal that separates the trachea from the esophagus, reducing the risk of food or fluids entering the lungs. Choices A, C, and D are incorrect because the cuff's primary function in a Tracheostomy tube is to prevent aspiration rather than separating the upper and lower airway, larynx from the nasopharynx, or securing the placement of the tube.

4. What is the primary function of a written nursing care plan?

A. Evaluates whether nursing care goals have been achieved
B. Ensures the provision of quality nursing care
C. Assists in selecting the appropriate nursing interventions
D. Facilitates the creation of a nursing diagnosis

Correct answer: D

Rationale: A written nursing care plan fundamentally serves to facilitate the development of a nursing diagnosis. This procedure involves analyzing patient data and identifying health problems that nurses can address independently. This analysis then aids in determining the most appropriate nursing interventions for the identified health issues. Although evaluating the achievement of nursing care goals is an important aspect, it is not the primary function of a nursing care plan. Similarly, while delivering quality nursing care is crucial, it is a broader concept that includes many other facets beyond just the initial nursing diagnosis and interventions.

5. Nonnutritive sweeteners are not metabolized by microorganisms and do not promote dental caries. Products made with a nonnutritive sweetener can be used as frequently as 8 to 10 times per day.

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: C

Rationale: The first statement is true; nonnutritive sweeteners do not promote caries. However, the second statement is false because products with nonnutritive sweeteners should still be consumed in moderation.
