Nursing Elites

1. Which respiratory structure is responsible for the humidification and warming of inhaled air?

• A. Trachea
• B. Larynx
• C. Nasal passages
• D. Bronchi

Correct answer: c

Rationale: The correct answer is C: Nasal passages. The nasal passages are lined with mucous membranes that produce mucus to humidify and warm the inhaled air before it reaches the lungs. This process helps to protect the delicate lung tissues from drying out and becoming irritated. The trachea, larynx, and bronchi play important roles in the respiratory system, but specifically, the nasal passages are primarily responsible for humidifying and warming the air as it enters the body.

2. Which of the following is a risk factor for developing kidney stones?

• A. Consuming a diet rich in fruits and vegetables
• B. Maintaining adequate hydration with water
• C. Having a family history of kidney stones
• D. Regularly engaging in moderate exercise

Correct answer: C

Rationale: Having a family history of kidney stones is a risk factor for developing them because genetics play a role in kidney stone formation. Individuals with a family history are more likely to inherit genetic factors that increase the likelihood of developing kidney stones. While consuming a diet rich in fruits and vegetables, maintaining adequate hydration with water, and regularly engaging in moderate exercise are generally healthy habits that can help prevent kidney stones, they are not direct risk factors for developing them. Therefore, option C, having a family history of kidney stones, is the correct answer.

3. In the reaction 2Na + 2H2O → 2NaOH + H2, what is the limiting reactant when 3 moles of sodium react with 2 moles of water?

• A. Na
• B. H2O
• C. NaOH
• D. H2

Correct answer: a

Rationale: Sodium is the limiting reactant because it runs out first in a 1:1 ratio with water.

4. Aubrey thinks about primary nursing as a system to deliver care. Which of the following

• A. Collaborates with the physician
• B. Provides care to a group of patients together with a group of nurses
• C. Provides care for 5-6 patients during their hospital stay.
• D. Performs comprehensive initial assessment

Correct answer: D

Rationale: Primary nursing is a care delivery system where one nurse is responsible for the total nursing care needs of a group of patients throughout their hospital stay. This includes performing comprehensive initial assessments, developing care plans, coordinating with other healthcare team members, and providing direct patient care. Option D is the correct answer as it aligns with the core principles of primary nursing, emphasizing the nurse's role in conducting thorough assessments to ensure individualized and holistic care for each patient in their caseload. Options A, B, and C do not accurately reflect the key components of primary nursing, making them incorrect choices.

5. Balance the following redox reaction in acidic solution: I⁻ (aq) + Cr₂O₇²⁻ (aq) -> I₂ (aq) + Cr³⁺ (aq). Identify the oxidizing agent and reducing agent.

• A. I⁻ is oxidized, Crâ‚‚O₇²⁻ is reduced
• B. I⁻ is reduced, Crâ‚‚O₇²⁻ is oxidized.
• C. Both I⁻ and Crâ‚‚O₇²⁻ are oxidized.
• D. Both I⁻ and Crâ‚‚O₇²⁻ are reduced.

Correct answer: A

Rationale: . I⁻ loses an electron (oxidation), Cr₂O₇²⁻ gains electrons (reduction).

6. Why are noble gas elements generally unreactive?

• A. They are too large and cannot form bonds easily.
• B. They lack valence electrons in their outermost shell.
• C. They have strong bonds within their own molecules.
• D. They have already achieved stable electron configurations.

Correct answer: D

Rationale: They have already achieved stable electron configurations. With completely filled outermost shells, noble gas elements have no need to gain or lose electrons, minimizing their tendency to participate in chemical reactions.
