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: Circulating Nurse

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. When is Prevident indicated?

A. High caries risk
B. Crown and bridge work
C. Orthodontic decalcification
D. All of the above

Correct answer: D

Rationale: Prevident is indicated for all the situations listed in the choices. It is recommended for patients with a high risk of caries to reduce the risk of tooth decay. It is also used in dental procedures like crown and bridge work to strengthen enamel and prevent cavities. Furthermore, it is utilized for orthodontic decalcification to aid in remineralizing the tooth structure and prevent further damage. Therefore, the correct answer is 'All of the above.' While choices A, B, and C are individually correct, selecting 'All of the above' is the most appropriate as it encompasses all the possible indications for Prevident.

3. What percentage of body weight as fat does a woman with a healthy body composition typically average?

A. 5%
B. 15%
C. 25%
D. 35%

Correct answer: C

Rationale: A healthy body fat percentage for women typically ranges between 21% and 33%, with 25% being an average healthy body fat percentage. Choice A (5%) is too low for a healthy body fat percentage and is more in line with essential body fat levels. Choice B (15%) is also lower than the typical range for a healthy body fat percentage. Choice D (35%) is too high and would be considered high body fat for women.

4. What does a QRS Complex represent in an ECG reading?

A. Atrial depolarization
B. Ventricular repolarization
C. Ventricular depolarization
D. End of ventricular depolarization

Correct answer: C: Ventricular depolarization

Rationale: The QRS Complex in an ECG reading represents ventricular depolarization, which is the process of the heart's ventricles preparing to contract by changing the electrical charge in the cell, hence choice 'C' is the correct answer. Choice 'A' is incorrect because atrial depolarization is represented by the P wave in an ECG reading, not the QRS Complex. Choice 'B' is incorrect as ventricular repolarization is depicted by the T wave, not the QRS Complex. Finally, choice 'D' is also incorrect because the QRS Complex is not the end of ventricular depolarization, but the process itself.
