ATI Proctored Nutrition Exam
1. Churns chyme and has an environment of pH2; holds 4-6 cups of food:
- A. stomach
- B. pancreas
- C. large intestine
- D. small intestine
Correct answer: A
Rationale: The stomach churns food into chyme and has a highly acidic environment (pH 2) to aid in the digestion of proteins and other nutrients.
2. Select all that apply. Which nutrients are needed by the body to make hemoglobin?
- A. Iron
- B. Vitamin B12
- C. Niacin
- D. Folate
Correct answer: A
Rationale: The correct answer is A: Iron. Iron is an essential nutrient needed by the body to make hemoglobin, the protein in red blood cells that carries oxygen. While other nutrients like vitamin B12, niacin, and folate are important for various bodily functions, they are not directly involved in the production of hemoglobin. Vitamin B12 is essential for nerve function and DNA synthesis, niacin is important for metabolism, and folate is crucial for cell division and DNA synthesis. Therefore, only iron is specifically required for hemoglobin production.
3. High blood pressure is defined as systolic and diastolic measurements greater than or equal to:
- A. 140 mm Hg and 90 mm Hg, respectively
- B. 150 mm Hg and 80 mm Hg, respectively
- C. 160 mm Hg and 110 mm Hg, respectively
- D. 180 mm Hg and 120 mm Hg, respectively
Correct answer: A
Rationale: High blood pressure, or hypertension, is typically defined as having a systolic pressure of 140 mm Hg or higher and/or a diastolic pressure of 90 mm Hg or higher. Therefore, the correct answer is A. Choice B is incorrect because it suggests a higher systolic measurement than the standard definition. Choice C is incorrect as it provides an even higher systolic measurement and a much higher diastolic measurement. Choice D is also incorrect as it suggests extremely elevated blood pressure values, well above the typical definition of hypertension.
4. When can a patient's medical record become a potential issue for the doctor or nurse?
- A. When the record is extensive
- B. When a medical record is subpoenaed in court
- C. When it is missing
- D. When the medical record is inaccurate, incomplete, or inadequate
Correct answer: D
Rationale: The correct answer is D. A medical record becomes a potential issue for a doctor or a nurse when it is inaccurate, incomplete, or inadequate. This is because a medical record is a key tool for healthcare professionals to track a patient's history, treatment, and progress. If the record is not accurate or complete, it can lead to misdiagnosis, incorrect treatment, or other potential problems in patient care. While missing records (Choice C) could be a problem, they do not directly implicate the doctor or nurse in the same way that inaccurate or inadequate records do. An extensive record (Choice A) or a record being subpoenaed in court (Choice B) are not inherently problematic for healthcare professionals and do not necessarily reflect negatively on their work.
5. Each nonnutritive sweetener can be recommended to patients with phenylketonuria, except one. Which one is the exception?
- A. Cyclamate
- B. Acesulfame-K
- C. Saccharin
- D. Aspartame
Correct answer: D
Rationale: The correct answer is D, Aspartame. Aspartame contains phenylalanine, which is contraindicated for individuals with phenylketonuria (PKU), a genetic disorder that impairs phenylalanine metabolism. Therefore, patients with PKU should avoid aspartame. Choices A, B, and C (Cyclamate, Acesulfame-K, Saccharin) are considered safe for individuals with PKU as they do not contain phenylalanine and can be recommended as alternatives to sugar for these patients.
