ATI Nutrition Practice A

1. Riboflavin

A. Vitamin B1
B. Vitamin B2
C. Vitamin B3
D. Vitamin B12

Correct answer: B

Rationale: Riboflavin is also known as Vitamin B2, which is important for energy production and the metabolism of fats, drugs, and steroids.

2. Pain medications given to the burn clients are best given via what route?

A. IV C. Oral
B. IM D. SQ
C.
D.

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.

3. Which enzyme initiates protein digestion in the stomach?

A. Pepsin
B. Salivary Amylase
C. CCK
D. Secretin

Correct answer: A

Rationale: Pepsin is the enzyme that initiates protein digestion in the stomach. It breaks down proteins into smaller peptides, aiding in their further digestion and absorption in the intestines. Salivary Amylase (Choice B) functions in breaking down dietary carbohydrates in the mouth, not proteins. CCK (Choice C) and Secretin (Choice D) are hormones involved in the digestion of fats and carbohydrates, not proteins. Therefore, Choices B, C, and D are incorrect in the context of protein digestion in the stomach.

4. What is the movement of water from an area of lower solute concentration to one of higher solute concentration called?

A. Hypodipsia
B. Hypernatremia
C. Hypokalemia
D. Osmosis

Correct answer: D

Rationale: The correct answer is D, Osmosis. Osmosis is the process where water moves from an area of low solute concentration to an area of high solute concentration. This movement equalizes the solute concentration in intracellular and extracellular fluids. Choices A, B, and C are incorrect because they do not describe the movement of water based on solute concentration levels.

5. The oral cavity is the site of a wide variety of systemic disease manifestations due to:

A. Rapid cellular turnover
B. Constant attack by microorganisms
C. Trauma-intense environment
D. All of the above

Correct answer: D

Rationale: The oral cavity is indeed the site of various systemic disease manifestations due to multiple factors. Firstly, the rapid cellular turnover in the oral mucosa makes it susceptible to diseases. Secondly, the constant presence of microorganisms in the oral cavity contributes to the development of systemic diseases. Finally, the oral cavity being a trauma-intense environment further increases the risk of systemic manifestations. Therefore, all the provided options - rapid cellular turnover, constant attack by microorganisms, and a trauma-intense environment - play a role in making the oral cavity a site for various systemic diseases. Hence, the correct answer is 'All of the above.' Choices A, B, and C are incorrect individually as they each represent only one aspect of why the oral cavity is prone to systemic disease manifestations, whereas the correct answer encompasses all these factors.
