1. What is the pH of a solution with a hydrogen ion concentration of \(1 \times 10^{-9}\) M?

• A. 5
• B. 7
• C. 9
• D. 11

Correct answer: c

Rationale: The pH is calculated as the negative logarithm (base 10) of the hydrogen ion concentration. In this case, \(-\log(1 \times 10^{-9}) = 9\).

2. In the reaction 4Al + 3O2 → 2Al2O3, what is the mole ratio of aluminum to oxygen?

• A. 4:3
• B. 2:3
• C. 3:2
• D. 3:4

Correct answer: a

Rationale: The coefficients in the balanced equation represent the mole ratio, which is 4 moles of Al to 3 moles of O2.

3. Which of the following is the best guarantee that the patient’s priority needs are met?

• A. Checking with the relative of the patient
• B. Preparing a nursing care plan in collaboration with the patient
• C. Consulting with the physician
• D. Coordinating with other members of the team

Correct answer: B

Rationale: Preparing a nursing care plan in collaboration with the patient is the best guarantee that the patient's priority needs are met because it involves actively involving the patient in their own care. This approach ensures that the patient's preferences, concerns, and priorities are taken into account when planning their care. Checking with the relative of the patient, consulting with the physician, and coordinating with other team members are important aspects of patient care, but collaborating with the patient directly ensures a patient-centered approach that addresses their individual needs and preferences.

4. The statement, “The Good Shepherd Medical Center aims to provide patient-centered care in

• A. Vision
• B. Goal
• C. Philosophy
• D. Mission

Correct answer: A

Rationale: The correct answer is A: "Vision." A vision statement describes the desired future state or long-term goal of an organization. It outlines the aspirations and purpose of the organization, such as providing patient-centered care in this case. Vision statements are forward-looking and inspirational, guiding the organization towards achieving its ultimate objectives. In contrast, a goal is a specific, measurable, and achievable target within a set timeframe. A philosophy is a set of beliefs or guiding principles, while a mission statement defines the organization's core purpose and focus. Therefore, the statement about providing patient-centered care aligns with the concept of a vision statement.

5. What is the recommended daily fluid intake for adults?

• A. 1 liter
• B. 2 liters
• C. 3 liters
• D. 4 liters

Correct answer: B

Rationale: Rationale: The recommended daily fluid intake for adults is typically around 2 liters, which is equivalent to about 8 cups or half a gallon. This amount can vary depending on factors such as age, gender, weight, activity level, and climate. Staying adequately hydrated is essential for overall health and helps maintain proper bodily functions, such as regulating body temperature, aiding digestion, and transporting nutrients and oxygen throughout the body. Drinking enough fluids also helps prevent dehydration, which can lead to symptoms like fatigue, headaches, and dizziness. It's important to note that individual fluid needs may vary, so it's always best to consult with a healthcare provider for personalized recommendations.

6. What is the scientific term for the windpipe, a tube that carries air from the larynx to the bronchi?

• A. Pharynx
• B. Trachea
• C. Epiglottis
• D. Bronchiole

Correct answer: B

Rationale: The correct answer is B: Trachea. The trachea is the scientific term for the windpipe, which is a tube that carries air from the larynx to the bronchi. The pharynx is the throat area where the mouth and nasal passages meet. The epiglottis is a flap of tissue that covers the trachea during swallowing to prevent food from entering the airway. Bronchioles are smaller airway branches in the lungs. Therefore, the trachea best fits the description of a tube carrying air from the larynx to the bronchi.
