Nutrition ATI Proctored Exam 2023
1. Which item is typically fortified with iodine to address iodine deficiency in the population?
- A. Flour
- B. Salt
- C. Canned vegetables
- D. Drinking water
Correct answer: B
Rationale: Iodized salt is the correct answer. Iodine deficiency can lead to thyroid problems, so iodine is added to salt to ensure an adequate intake of this essential nutrient. Flour is often fortified with other nutrients like folic acid, iron, and niacin, but not iodine. Canned vegetables and drinking water are not typically fortified with iodine to address deficiency in the population.
2. A nurse is teaching a group of clients about stress. Which of the following should the nurse include in the teaching?
- A. Protein requirements decrease in times of stress.
- B. Acute stress causes an increase in metabolism.
- C. Stress causes a positive nitrogen balance in the body.
- D. Glucose is broken down more slowly during times of stress.
Correct answer: B
Rationale: The correct answer is B: Acute stress causes an increase in metabolism. During acute stress, the body's fight-or-flight response is activated, leading to an increase in metabolism to provide energy for the body to respond to the stressor. Choices A, C, and D are incorrect. Protein requirements actually increase during times of stress to support the body's needs. Stress typically leads to a negative nitrogen balance in the body, not a positive one. Glucose is broken down more rapidly, not slowly, during times of stress to provide immediate energy.
3. When carbohydrates are eliminated from the diet to lose weight, which nutrients are most likely to become insufficient?
- A. Iron, fiber, and protein
- B. Iron, fiber, and vitamin K
- C. Vitamin A and vitamin C
- D. Iron, fiber, and B vitamins
Correct answer: D
Rationale: Iron, fiber, and B vitamins are most likely to become insufficient when carbohydrates are eliminated from the diet to lose weight. Carbohydrates are a primary source of B vitamins and fiber in the diet. Iron can also be obtained from plant-based sources like legumes and whole grains, which are often eliminated when carbohydrates are restricted. Choices A, B, and C are incorrect because protein, vitamin K, vitamin A, and vitamin C are not primarily sourced from carbohydrates and are less likely to become insufficient solely due to carbohydrate elimination.
4. When performing endotracheal suctioning, the nurse applies suctioning while withdrawing and gently rotating the catheter 360 degrees for which of the following time periods?
- A. 10-15 seconds
- B. 30-35 seconds
- C. 20-25 seconds
- D. 0-5 seconds
Correct answer: D
Rationale: During endotracheal suctioning, the nurse should apply suctioning while withdrawing and gently rotating the catheter 360 degrees for a short period of 0-5 seconds. This brief duration helps minimize the risk of hypoxia and trauma to the airway. Choices A, B, and C suggest longer time periods for suctioning, which can increase the risk of complications such as hypoxia, mucosal damage, and the removal of excess amounts of airway secretions.
5. Which of the following is a tricyclic antidepressant drug?
- A. Venlafaxine (Effexor)
- B. Fluoxetine (Prozac)
- C. Sertraline (Zoloft)
- D. Imipramine (Tofranil)
Correct answer: D
Rationale: Imipramine (Tofranil) is a tricyclic antidepressant drug. This class of medications is used to treat depression, and they work by increasing the levels of certain chemicals in the brain that help lift mood. On the other hand, Venlafaxine (Effexor) is a serotonin and norepinephrine reuptake inhibitor (SNRI), Fluoxetine (Prozac) is a selective serotonin reuptake inhibitor (SSRI), and Sertraline (Zoloft) is also an SSRI. Therefore, they are not classified as tricyclic antidepressants.
