ATI Nutrition Proctored Exam 2023

1. Which chemical structure is represented by glycerol combined with two fatty acids?

A. Compound lipids
B. Monoglycerides
C. Diglycerides
D. Structural lipids

Correct answer: C

Rationale: The correct answer is C: Diglycerides. A diglyceride is a glycerol molecule combined with two fatty acids. This is a common form of fat during digestion and absorption. Choice A, Compound lipids, is incorrect because these lipids are composed of simple lipids plus additional compounds, which is not the case with a glycerol molecule combined with two fatty acids. Choice B, Monoglycerides, is incorrect because these are glycerol molecules combined with only one fatty acid, not two. Lastly, choice D, Structural lipids, is incorrect because these are major components of cell membranes and do not directly relate to the combination of glycerol and two fatty acids.

2. A nurse is assessing a client who reports muscle spasms in his calves and tingling in his hands. The client indicates consuming a low intake of milk products and green leafy vegetables. The nurse should identify that the client's findings indicate a deficiency in which of the following sources of nutrition?

A. Iron
B. Omega-3 fatty acids
C. Vitamin C
D. Calcium

Correct answer: D

Rationale: The correct answer is D, Calcium. Muscle spasms and tingling suggest a calcium deficiency, which is commonly associated with a low intake of milk products and green leafy vegetables. Iron (choice A) deficiency typically presents with fatigue and weakness, not muscle spasms and tingling. Omega-3 fatty acids (choice B) are essential for brain function and heart health, but their deficiency does not manifest as muscle spasms and tingling. Vitamin C (choice C) deficiency leads to scurvy with symptoms like bleeding gums and bruising, not muscle spasms and tingling.

3. An emerging technique in screening for Breast Cancer in developing countries like the Philippines is:

A. Mammography once a year starting at the age of 50
B. Clinical BSE Once a year
C. BSE Once a month
D. Pap smear starting at the age of 18 or earlier if sexually active

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

4. What is the priority nursing goal for an adolescent with anorexia nervosa?

A. Encourage effective coping skills
B. Restore normal eating habits
C. Stop weight loss or restore weight
D. Promote realistic self-image

Correct answer: C

Rationale: The priority nursing goal for an adolescent with anorexia nervosa is to stop weight loss or restore weight. This is crucial in addressing the immediate health risks associated with anorexia nervosa, such as malnutrition, organ damage, and potential life-threatening complications. While encouraging effective coping skills, restoring normal eating habits, and promoting a realistic self-image are important aspects of treatment, stopping weight loss or restoring weight takes precedence due to the severe physical consequences of anorexia nervosa.
