Nursing Elites

1. The process of a liquid changing into a gas is called:

• A. Evaporation
• B. Boiling
• C. Condensation
• D. Sublimation

Correct answer: A

Rationale: Evaporation occurs at any temperature, while boiling only occurs at the boiling point of the liquid.

2. What is the term for the inflammation of the airways in the lungs, often causing wheezing and difficulty breathing?

• A. Pneumonia
• B. Emphysema
• C. Asthma
• D. Pleurisy

Correct answer: C

Rationale: The correct answer is C: "Asthma." Asthma is a chronic condition characterized by inflammation of the airways in the lungs, leading to symptoms like wheezing, shortness of breath, coughing, and chest tightness. Pneumonia (A) is an infection in the lungs caused by bacteria, viruses, or fungi. Emphysema (B) is a type of chronic obstructive pulmonary disease (COPD) characterized by damage to the air sacs in the lungs. Pleurisy (D) is inflammation of the lining of the lungs and chest cavity. Therefore, asthma best fits the description provided in the question, making it the correct answer.

3. Katherine is a young Unit Manager of the Pediatric Ward. Most of her staff nurses are senior

• A. Identify the source of the conflict and understand the points of friction
• B. Disregard what she feels and continue to work independently
• C. Seek help from the Director of Nursing
• D. Quit her job and look for another employment.

Correct answer: C

Rationale: The correct answer is C: Seek help from the Director of Nursing. As a young Unit Manager managing a team of senior staff nurses, Katherine may face challenges in leading and gaining the respect of her team due to the age and experience gap. Seeking help from the Director of Nursing can provide her with guidance, mentorship, and support in navigating these challenges. It is important for Katherine to communicate openly about any conflicts or issues she may be facing in order to address them effectively and maintain a positive work environment. Quitting her job (option D) should be considered as a last resort after exhausting all other possible solutions.

4. A balanced chemical equation for the reaction between sodium and chlorine to form sodium chloride is:

• A. Na + Cl2 -> NaCl
• B. 2Na + Cl2 -> 2NaCl
• C. Na2 + Cl -> 2NaCl
• D. Na + 2Cl -> NaCl2

Correct answer: A

Rationale: The correct balanced chemical equation for the reaction between sodium and chlorine to form sodium chloride is '2Na + Cl2 -> 2NaCl'. This equation is balanced as it shows that 2 atoms of sodium react with 1 molecule of chlorine gas to produce 2 molecules of sodium chloride. Option A 'Na + Cl2 -> NaCl' is incorrect as it does not balance the number of atoms on both sides of the equation. It only shows 1 atom of sodium reacting with 1 molecule of chlorine, which is not a balanced representation of the chemical reaction. Therefore, option B is the correct choice for this question.

5. Which property of a substance measures the amount of matter per unit volume?

• A. Density
• B. Mass
• C. Weight
• D. Volume

Correct answer: a

Rationale: Density is the property that measures the amount of matter (mass) per unit volume of a substance. It is calculated as mass divided by volume.

6. What information can be obtained from the mass number of an element?

• A. The number of protons in the nucleus
• B. The total number of protons and neutrons
• C. The number of electrons in the valence shell
• D. The element's chemical reactivity

Correct answer: B

Rationale: The mass number of an element represents the total number of protons and neutrons in the nucleus. This information is crucial for determining the atomic mass of the element and understanding its stability and isotopes. The number of protons in the nucleus (option A) is represented by the atomic number, not the mass number. The number of electrons in the valence shell (option C) is related to the element's position in the periodic table and its chemical properties, but it is not directly determined by the mass number. The element's chemical reactivity (option D) is influenced by the number and arrangement of electrons in the atom's energy levels, not by the mass number.
