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. Each of the following is a function of vitamin A, except one. Which is the exception?
- A. Prevention of night blindness
- B. Growth of soft tissues and bone
- C. Maintenance of more than 200 genes
- D. Integrity of body openings and their linings
Correct answer: C
Rationale: The correct answer is C. Maintenance of more than 200 genes is not a function of vitamin A; instead, it is a function of Vitamin D. Vitamin A plays a crucial role in the prevention of night blindness by aiding in the production of the visual pigment rhodopsin. It also supports the growth of soft tissues and bone, as well as the integrity of body openings and their linings. Choice C is incorrect because the maintenance of genes is primarily associated with Vitamin D, not Vitamin A.
3. A nurse is preparing a teaching plan for a client who has neutropenia as a result of radiation therapy for the treatment of lung cancer. Which of the following should the nurse plan to include in the teaching?
- A. Bottled water is an appropriate choice to increase fluid intake.
- B. The salad bar is a healthy choice when dining out.
- C. Soft-boiled eggs are an appropriate source of protein.
- D. Eating at a buffet is a good choice to increase caloric intake.
Correct answer: A
Rationale: In neutropenia, which is a low count of neutrophils, the client is at a high risk of infection. It is crucial to emphasize the importance of proper hydration to maintain overall health. Bottled water is a safe choice as it reduces the risk of exposure to contaminants that could further compromise the client's immune system. The other options, like the salad bar, soft-boiled eggs, and eating at a buffet, may not be suitable for a client with neutropenia due to the risk of bacterial contamination or exposure to pathogens that could lead to infections, which should be avoided.
4. Medication for treating high blood cholesterol levels should not be used for most people unless:
- A. The patient has at least three major risk factors for coronary heart disease
- B. The patient has been experiencing symptoms of coronary heart disease for at least three months
- C. The patient's medical insurance covers prescription drugs
- D. Treatment with Therapeutic Lifestyle Changes (TLC) alone is unsuccessful after three months
Correct answer: D
Rationale: The correct answer is choice D because medication for high cholesterol is typically not considered unless Therapeutic Lifestyle Changes (TLC), which include diet and exercise, have not proven effective after a three-month period. This approach ensures that lifestyle modifications are given a fair chance to lower cholesterol levels before resorting to medication. Choice A is incorrect because the number of risk factors for coronary heart disease does not dictate when to begin medication; it is about the effectiveness of lifestyle changes. Choice B is incorrect as the duration of coronary heart disease symptoms does not determine when to start medication; the focus is on the response to TLC. Choice C is incorrect because the coverage of prescription drugs by the patient's insurance does not influence the medical decision to use medication for high cholesterol; it is based on medical necessity and effectiveness of prior interventions.
5. Which is the priority nursing diagnosis for a patient with an indwelling urinary catheter?
- A. Self-esteem disturbance
- B. Impaired urinary elimination
- C. Impaired skin integrity
- D. Risk for infection
Correct answer: D
Rationale: The correct answer is 'D: Risk for infection.' An indwelling urinary catheter poses a significant risk for infection due to its invasive nature and the increased susceptibility to urinary tract infections. While 'B: Impaired urinary elimination' and 'C: Impaired skin integrity' may also be concerns for a patient with an indwelling urinary catheter, the immediate risk of infection is the priority. 'A: Self-esteem disturbance' is not typically a priority nursing diagnosis for a patient with an indwelling urinary catheter because the focus is primarily on infection prevention and management to ensure patient safety and well-being.
