1. She knows that performance appraisal consists of all the following activities EXCEPT:

A. Setting specific standards and activities for individual performance.
B. Using agency standards as a guide.
C. Determine areas of strength and weaknesses
D. Focusing activity on the correction of identified behavior.

Correct answer: D

Rationale: The correct answer is D: 'Focusing activity on the correction of identified behavior.' Performance appraisal is a process that involves setting specific standards and activities for individual performance, using agency standards as a guide, and determining areas of strengths and weaknesses. While performance appraisal may identify areas for improvement, its primary focus is not solely on correcting behavior. Instead, it is a holistic evaluation of an individual's performance in various aspects. Therefore, option D is the exception among the activities associated with performance appraisal.

2. A nurse needs to administer 0.8 milliliters of medication. The only available syringe measures in teaspoons. How many teaspoons should the nurse use?

A. 0.2 teaspoons
B. 0.4 teaspoons
C. 0.6 teaspoons
D. 0.8 teaspoons

Correct answer: B

Rationale: Rationale: 1 milliliter is equivalent to approximately 0.2 teaspoons. Therefore, to find out how many teaspoons are in 0.8 milliliters, we can set up a proportion: 0.8 milliliters * 0.2 teaspoons/1 milliliter = 0.16 teaspoons Since 0.16 teaspoons is not one of the answer choices, we need to convert it to a more practical measurement. The closest option is 0.4 teaspoons, which is the correct answer.

3. The energy absorbed during a chemical reaction is called:

A. Kinetic energy
B. Potential energy
C. Heat energy
D. Endothermic energy

Correct answer: D

Rationale: Endothermic means "inward heat," indicating energy is absorbed during the reaction.

4. Regular exercise is beneficial for the muscular system by:

A. Decreasing muscle mass
B. Improving muscle strength and endurance
C. Making muscles less flexible
D. Increasing the risk of muscle tears

Correct answer: B

Rationale: The correct answer is B: 'Improving muscle strength and endurance.' Regular exercise is beneficial for the muscular system as it helps to strengthen muscles and increase endurance. By engaging in consistent physical activity, muscles adapt and grow stronger, which can enhance overall physical performance and reduce the risk of injury. Exercise also improves blood flow to the muscles, aiding in their recovery and growth. It does not decrease muscle mass (A), make muscles less flexible (C), or increase the risk of muscle tears (D), as long as proper form and gradual progression are followed.

5. Two identical balls, one made of clay and the other made of steel, are dropped from the same height. Which ball reaches the ground first, neglecting air resistance?

A. The clay ball due to its lower density
B. The steel ball due to its higher density
C. Both balls reach the ground simultaneously
D. It depends on the initial velocities of the balls

Correct answer: C

Rationale: In a vacuum (neglecting air resistance), the acceleration due to gravity is constant for all objects regardless of their mass or composition. This means both balls will experience the same acceleration and reach the ground at the same time.

6. The patella, commonly known as the kneecap, is an example of a:

A. Sesamoid bone
B. Long bone
C. Short bone
D. Irregular bone

Correct answer: A

Rationale: The patella, or kneecap, is a sesamoid bone. Sesamoid bones are small bones that develop within tendons, typically where they pass over joints. The patella functions to protect the knee joint and enhance the leverage of the quadriceps muscle. Its location and function align with those of a sesamoid bone, making option A the correct choice. Long bones, such as the femur, are characterized by their elongated shape and serve as levers for movement. Short bones, like those in the wrist and ankle, provide support and stability. Irregular bones, such as the vertebrae, have complex shapes and functions. Therefore, option A is the most appropriate answer in this context.
