ATI Nutrition Practice A

1. All of the following are electrolytes except:

Correct answer: D

Rationale: Iron is not an electrolyte; electrolytes like sodium, potassium, and chloride help maintain fluid balance and are critical for nerve and muscle function.

2. When assessing Richard for chest percussion or chest vibration and postural drainage, Mario would focus on the following EXCEPT:

Correct answer: B

Rationale: The correct answer is B because when assessing Richard for chest percussion or chest vibration and postural drainage, Mario would focus on various aspects such as the amount of food and fluid taken before treatment to prevent complications during the procedure, teaching the client's relatives to perform the procedure correctly, and following the doctor's orders regarding position restrictions and the client's tolerance for lying flat. Respiratory rate, breath sounds, and location of congestion would be assessed during the procedure itself, not as part of the pre-assessment.

3. On the study “effects of effective nurse-patient communication in decreasing anxiety of post operative patients” What is the Dependent variable?

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

4. Magnesium's major functions in the body would be least likely to include which of the following?

Correct answer: D

Rationale: Magnesium plays a key role in muscle relaxation, enzyme operation, and protein synthesis, but it is not directly involved in regulating body temperature.

5. What differentiates one amino acid from another?

Correct answer: C

Rationale: The side chain, also known as the R group, is what differentiates one amino acid from another. It imparts unique properties to each amino acid, thereby influencing their roles and functions in proteins. The amine group (Choice A) and the acid group (Choice B) are components of all amino acids and do not cause the differences among various amino acids. Choice D is incorrect as it suggests that none of the given options account for the differences, which is not true as the side chain does.
