1. What is the stoichiometric coefficient of nitrogen (N2) in the balanced equation for the Haber process: N2 + 3H2 → 2NH3?
- A. 1
 - B. 2
 - C. 3
 - D. 4
 
Correct answer: a
Rationale: The coefficient of N2 is 1 in the balanced equation
2. When Harry uses team nursing as a care delivery system, he and his team need to assess the
- A. Each patient as listed on the worksheet
 - B. Patients who needs least care
 - C. Medications and treatments required for all patients
 - D. Patients who need the most care
 
Correct answer: C
Rationale: When Harry uses team nursing as a care delivery system, he and his team need to assess the medications and treatments required for all patients. In team nursing, different team members are responsible for specific aspects of patient care, such as medications and treatments. Assessing the medications and treatments required for all patients ensures that each patient receives appropriate and timely care. This approach helps in coordinating care effectively among team members and prevents errors or omissions in patient treatment. Therefore, option C is the correct answer as it aligns with the principles of team nursing and patient-centered care.
3. Identify the predicate in the following sentence: "The children built a sandcastle on the beach."
- A. on the beach
 - B. built a sandcastle
 - C. children
 - D. the
 
Correct answer: B
Rationale: The predicate is the verb and any words following it that describe the action or state of being of the subject.
4. Which element has the same number of protons and neutrons?
- A. Carbon (C)
 - B. Oxygen (O)
 - C. Lithium (Li)
 - D. Helium (He)
 
Correct answer: D
Rationale: Helium (He) - He-4 has 2 protons and 2 neutrons, while the other options have differing numbers.
5. What is the relationship between the frequency and period of a wave?
- A. They are unrelated
 - B. Frequency = Period
 - C. Frequency = 1/Period
 - D. Period = 1/Frequency
 
Correct answer: D
Rationale: The correct relationship between frequency and period of a wave is that Period = 1/Frequency. This means that the period of a wave is the reciprocal of its frequency. Frequency is the number of complete cycles of a wave that occur in a unit of time, while the period is the time it takes for one complete cycle of the wave to occur. Since frequency and period are inversely related, the correct formula is Period = 1/Frequency.
6. The outermost layer of the skin, providing protection against pathogens and the environment, is the:
- A. Dermis
 - B. Epidermis
 - C. Hypodermis
 - D. Stratum corneum (part of the epidermis)
 
Correct answer: D
Rationale: The correct answer is D, 'Stratum corneum (part of the epidermis).' The stratum corneum is the outermost layer of the epidermis, consisting of dead skin cells that provide a protective barrier against pathogens and environmental factors. The dermis is located beneath the epidermis and contains connective tissue, nerves, and blood vessels. The hypodermis is the deepest layer of the skin, consisting of fat and connective tissue. Understanding the layers of the skin and their functions is essential for comprehending the skin's role in protecting the body.
