ATI Nutrition Practice Test A 2019
1. During operation, who manages the lighting, noise, temperature and other factors in the operating room suite?
- A. Nurse Supervisor
- B. Surgeon
- C. Circulating Nurse
- D. Scrub Nurse
Correct answer: C
Rationale: In an operating room, the circulating nurse is responsible for managing environmental factors such as lighting, noise, and temperature. This role includes ensuring the comfort and safety of the patient, as well as the efficiency of the team. While the Nurse Supervisor, Surgeon, and Scrub Nurse also have crucial roles during an operation, they do not directly manage the environmental conditions of the operating room. The rationale provided does not directly address the question asked, and appears to relate more to the broader role of nursing in patient care.
2. Each statement regarding the correlation between vitamin D and sun exposure is accurate, except one. Which is the exception?
- A. The body can produce sufficient amounts of vitamin D from sunlight.
- B. UV radiation can convert a precursor of vitamin D to vitamin D3 by penetrating uncovered skin.
- C. Sunscreen blocks the formation of vitamin D3.
- D. By the age of 70 years, the skin generally produces vitamin D at only half the level it did at the age of 20 years.
Correct answer: C
Rationale: While UV radiation can penetrate uncovered skin and convert a precursor of vitamin D to vitamin D3, sunscreen does block the formation of vitamin D3. Sunscreen is recommended by dermatologists to prevent sunburn and reduce the risk of skin cancer. The other choices are correct: the body can produce sufficient vitamin D from sunlight, UV radiation can convert a precursor of vitamin D to vitamin D3, and skin generally produces less vitamin D as a person ages.
3. Which of the following is a normal finding during assessment of a Chest tube in a 3 way bottle system?
- A. There is a continuous bubbling in the drainage bottle
- B. There is an intermittent bubbling in the suction control bottle
- C. The water fluctuates during inhalation of the patient
- D. There is 3 cm of water left in the water seal bottle
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. Which vitamin is essential for proper blood clotting?
- A. Vitamin A
- B. Vitamin E
- C. Vitamin K
- D. Vitamin C
Correct answer: C
Rationale: Vitamin K is vital for the synthesis of clotting factors, which are necessary for proper blood clotting. Vitamin A (Choice A) is important for vision and skin health, not blood clotting. Vitamin E (Choice B) is an antioxidant that helps protect cells from damage but is not directly involved in blood clotting. Vitamin C (Choice D) is essential for collagen synthesis and a healthy immune system, but it does not play a direct role in blood clotting.
5. Which cells in the islet of the pancreas are responsible for synthesizing insulin?
- A. Alpha cells
- B. Beta cells
- C. Gamma cells
- D. Delta cells
Correct answer: B
Rationale: Beta cells in the islets of Langerhans in the pancreas are responsible for the production and secretion of insulin, which is crucial for regulating blood glucose levels. Alpha cells, on the other hand, produce glucagon, a hormone that raises blood glucose levels. Gamma cells and Delta cells do not exist in the islets of Langerhans; therefore, they are incorrect choices.
