Nursing Elites

1. When analyzing a power plant, which of the following is NOT considered a part of the system?

• A. The fuel being burned.
• B. The working fluid (e.g., steam or water).
• C. The turbine that generates electricity.
• D. The surrounding air.

Correct answer: D

Rationale: In a power plant system, the components directly involved in the energy conversion process are considered part of the system. The fuel being burned provides the heat source, the working fluid transfers this heat energy, and the turbine converts it into mechanical energy to generate electricity. The surrounding air, while it may interact with the system, is not a component that directly participates in the energy conversion process within the power plant system. Therefore, the correct answer is D - The surrounding air. Choices A, B, and C are essential components of a power plant system as they play direct roles in the energy conversion process, unlike the surrounding air.

2. What would be an appropriate nursing response when a mother reports that her 16-month-old toddler has an earache?

• A. Maybe the toddler is just teething.
• B. I will check her ear for an ear infection.
• C. Are you sure the toddler is really in pain?
• D. Please describe what the toddler is doing to indicate she is in pain.

Correct answer: B

Rationale: The appropriate nursing response would be to assess the toddler's ear to determine if there is indeed an ear infection causing the earache. It is crucial to provide timely and suitable care for the child's pain and discomfort. Checking for an ear infection is a necessary step in evaluating the source of the toddler's earache. Choice A is incorrect as it assumes the earache is due to teething without proper assessment. Choice C questions the mother's report rather than focusing on the child's condition. Choice D is not as direct and focused as directly examining the ear for a possible infection.

3. What is the function of the gallbladder in the digestive system?

• A. To produce bile
• B. To store and concentrate bile
• C. To detoxify harmful substances
• D. To regulate blood sugar

Correct answer: B

Rationale: The gallbladder's main function is to store and concentrate bile produced by the liver. Bile is essential for the digestion and absorption of fats in the small intestine. Therefore, the correct answer is B, as the gallbladder acts as a reservoir for bile rather than producing it. Choices A, C, and D are incorrect because the gallbladder does not produce bile, detoxify harmful substances, or regulate blood sugar in the digestive system.

4. In which phase of mitosis do new nuclear membranes form around sets of chromosomes?

• A. Prophase
• B. Anaphase
• C. Telophase
• D. Interphase

Correct answer: C

Rationale: The correct answer is C, Telophase. During telophase, the final phase of mitosis, new nuclear membranes form around sets of chromosomes at the opposite poles of the cell. This process marks the completion of nuclear division in mitosis. Choices A, B, and D are incorrect because in prophase, chromosomes condense but nuclear membranes are not formed; in anaphase, chromosomes separate and move to opposite poles but no new nuclear membranes are formed; and in interphase, the cell prepares for division but nuclear membranes are not forming around sets of chromosomes.

5. A stye is an infection of the ___________.

• A. eyelid
• B. eardrum
• C. nostril
• D. scalp

Correct answer: A

Rationale: A stye is an infection that occurs at the base of an eyelash or on the eyelid. It is typically caused by a bacterial infection, leading to redness, swelling, and sometimes discomfort in the affected area. Choices B, C, and D are incorrect because a stye specifically refers to an infection of the eyelid area, not the eardrum, nostril, or scalp.
