ATI Nutrition Proctored Exam 2023 Test Bank

1. Where does most nutrient digestion and absorption occur?

A. Large intestine
B. Small intestine
C. Stomach
D. Mouth

Correct answer: B

Rationale: The small intestine is the correct answer. It is the primary site for nutrient digestion and absorption in the digestive system. The small intestine plays a crucial role in breaking down carbohydrates, proteins, and fats into forms that can be absorbed by the body. While the large intestine absorbs water and electrolytes, the majority of nutrient absorption occurs in the small intestine. The stomach primarily functions in the initial digestion of proteins, and the mouth begins the mechanical breakdown of food through chewing.

2. A patient is being cared for by a nurse who has stomatitis following radiation treatment. Which of the following is an appropriate intervention for the nurse to take?

A. Serve foods without sauces or gravies
B. Offer mouth rinses with normal saline and water
C. Serve foods while still at a hot temperature
D. Instruct the client to drink liquids without a straw

Correct answer: B

Rationale: Offering mouth rinses with normal saline and water is an appropriate intervention for a nurse caring for a patient with stomatitis following radiation treatment. This intervention can help soothe and clean the mouth, promoting comfort and oral hygiene. Choice A is incorrect because serving foods without sauces or gravies does not directly address the client's stomatitis. Choice C is incorrect because serving hot foods can exacerbate discomfort in the client's mouth. Choice D is incorrect because using a straw can help in preventing further irritation in the client's mouth.

B. Owned by the doctor in charge and should be kept from the administrator for whatever reason
C. Owned by the hospital and should not be given to anyone who request it other than the doctor in charge
D. Owned by the patient and should be given by the nurse to the client as requested

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. What is the most effective way to limit the number of microorganisms in the hospital?

A. Using strict aseptic technique in all procedures
B. Wearing a mask and gown when caring for all patients with communicable diseases
C. Sterilizing all instruments
D. Handwashing

Correct answer: A

Rationale: The most effective way to limit the number of microorganisms in the hospital is by using strict aseptic technique in all procedures. This approach ensures that the risk of introducing harmful microorganisms into the hospital environment or patients is minimized. Choice B, wearing a mask and gown when caring for patients with communicable diseases, is important but not as comprehensive as using aseptic technique in all procedures. Sterilizing all instruments (Choice C) is crucial for preventing infections but may not address all avenues of microorganism transmission. Handwashing (Choice D) is a fundamental practice in infection control but alone may not be as effective as utilizing aseptic techniques in all procedures to limit microorganisms in the hospital.
