Nursing Elites

ATI TEAS 7

Biology

1. Recognize the opposing muscle pair.

Correct answer: A

Rationale: The bicep and tricep muscles are antagonistic muscle pairs, meaning they work in opposition to each other. The bicep is located on the front of the upper arm and is responsible for flexing the elbow joint. The tricep is located on the back of the upper arm and is responsible for extending the elbow joint.

2. Differentiate between epithelial and connective tissue.

Correct answer: B

Rationale: Epithelial tissue covers surfaces and lines organs, while connective tissue provides support and structure throughout the body. Both are composed of cells, but their functions and locations differ.

3. How is power defined in terms of physics?

Correct answer: a

Rationale: Power is defined as the rate at which work is done or the rate at which energy is transferred or converted.

4. Positron emission tomography (PET) scans utilize a key property of positrons for medical imaging. What is this property?

Correct answer: B

Rationale: The correct answer is B: 'Positive charge.' Positron emission tomography (PET) scans rely on the fact that positrons are positively charged particles. When a positron is emitted during radioactive decay, it quickly collides with an electron, resulting in annihilation and the release of two gamma rays in opposite directions. These gamma rays are detected by the PET scanner to create detailed images of the body's internal organs and tissues. The positive charge of positrons is crucial for this process to occur, making option B the correct choice.

5. What is the main topic of the passage?

Correct answer: B

Rationale: The passage focuses on the specific issue of microplastics in the marine environment and their harmful effects.

6. Which of the following guidelines should be least considered in formulating objectives for

Correct answer: D

Rationale: When formulating objectives for a written nursing care plan, staff preferences should be least considered. Objectives should be based on patient needs, evidence-based practice, and professional standards rather than personal preferences of the staff. Prescribed standards ensure quality care and adherence to best practices. A holistic approach considers the whole patient, including physical, emotional, and spiritual aspects. Staff preferences may introduce bias and should not dictate patient care objectives.
