ATI Nutrition Practice A

- A. chloride
- B. potassium

2. A client who is in her second trimester of pregnancy should increase her caloric intake by how many calories during this trimester?
- A. 110 cal/day
- B. 225 cal/day
- C. 340 cal/day
- D. 450 cal/day
Correct answer: C
Rationale: During the second trimester of pregnancy, it is recommended that a client increases their caloric intake by around 340 calories per day to support the growing needs of both the mother and the developing fetus. This additional intake helps ensure the proper nutrition and energy levels required during this crucial stage of pregnancy. Option A (110 cal/day) is too low to meet the increased demands. Option B (225 cal/day) is also below the recommended amount. Option D (450 cal/day) is higher than necessary and could lead to excessive weight gain, which is not ideal during pregnancy.
3. An estimated _____ percent of persons in the United States who have HIV infection are unaware that they are infected.
- A. 4%
- B. 21%
- C. 34%
- D. 49%
Correct answer: B
Rationale: The correct answer is B: '21%'. Approximately 21% of persons in the United States who have HIV infection are unaware that they are infected. This percentage represents a significant portion of individuals who are not aware of their HIV status, highlighting the importance of increased testing and awareness campaigns. Choices A, C, and D are incorrect as they do not align with the estimated percentage provided in the context.
4. Considering the statement that communication is most effective when barriers are first removed, which of the following is recognized as an inhibiting factor in communication?
- A. Avoidance of universally accepted abbreviations
- B. Usage of incorrect grammar
- C. Poor handwriting
- D. Advanced age of the client
Correct answer: D
Rationale: The correct answer is 'D: Advanced age of the client.' Age can be a significant obstacle in communication due to factors such as hearing loss, cognitive decline, or memory issues, which all can hamper effective communication. Choices A, B, and C, while they may present challenges in communication, are not directly related to age and its influence on communication, making them incorrect. The issues presented by not using universally accepted abbreviations, incorrect grammar, and poor handwriting can be resolved through clarification, education, or the use of alternative communication methods, unlike the difficulties that can arise from advanced age.
