Nursing Elites

1. As a nursing student triaging a patient, which of the following is an example of quantitative data you can gather?

• A. The patient says he feels pain.
• B. The patient says he has stabbing pain.
• C. The patient's temperature is 101.7°F.
• D. The patient reports that he had a fever yesterday.

Correct answer: C

Rationale: The corrected choice C, 'The patient's temperature is 101.7°F,' is an example of quantitative data because it provides a specific numerical value that can be measured. Quantitative data involves measurable and numerical information, making it crucial for assessing a patient's condition objectively. Choices A and B are subjective statements based on the patient's perception of pain and its description, which are qualitative data and may vary between individuals. Choice D provides historical information about a fever, which is not a current measurable value and does not constitute quantitative data for immediate assessment.

2. The Becquerel (Bq) is the designated unit for quantifying:

• A. Electron volt (eV) measurements of energy
• B. Radioactivity
• C. Electric charge (Coulombs)
• D. Force (Newtons)

Correct answer: B

Rationale: The Becquerel (Bq) is the unit used to measure radioactivity, specifically the activity of a quantity of radioactive material. It represents the number of radioactive disintegrations or transformations per unit of time. Choice A, electron volt (eV), is a unit of energy, not radioactivity. Choice C, electric charge (Coulombs), is measured in Coulombs, not Becquerels. Choice D, force (Newtons), is a unit of force, not radioactivity. Therefore, the correct answer is B.

3. Which of the following lobes of the brain is responsible for processing auditory sounds?

• A. Frontal
• B. Occipital
• C. Parietal
• D. Temporal

Correct answer: D

Rationale: The correct answer is D: Temporal. The temporal lobe of the brain is responsible for processing auditory sounds. It is also involved in memory and language functions. Choice A, Frontal lobe, is primarily associated with functions such as decision-making, problem-solving, and planning. Choice B, Occipital lobe, is responsible for processing visual information. Choice C, Parietal lobe, is involved in processing sensory information like touch, temperature, and pressure. Therefore, the temporal lobe is the specific lobe responsible for processing auditory information, making it the correct answer.

4. What phenomenon occurs when light passes through a medium without changing direction, such as when passing through a window?

• A. Diffraction
• B. Reflection
• C. Dispersion
• D. Transmission

Correct answer: D

Rationale: The correct answer is 'Transmission.' Transmission refers to the phenomenon where light passes through a medium without changing direction, as observed when light passes through a window. Diffraction involves the bending of light waves around obstacles, reflection is the bouncing back of light waves from a surface, and dispersion is the separation of light into its different colors. In this case, the question specifically asks about the situation where light passes through a medium without changing direction, which aligns with the process of transmission.

5. What is the primary purpose of control rods within a nuclear reactor?

• A. Reflecting neutrons back into the core
• B. Absorbing excess neutrons to control criticality
• C. Moderating the velocity of neutrons
• D. All of the above

Correct answer: B

Rationale: The primary purpose of control rods in a nuclear reactor is to absorb excess neutrons to control criticality. When inserted into the reactor core, control rods absorb neutrons, reducing the number available for sustaining the fission chain reaction. This action allows operators to manage the reactor power levels and prevent overheating or runaway reactions. Reflecting neutrons back into the core and moderating neutron velocity are not the primary functions of control rods in a nuclear reactor. Choice A is incorrect because control rods do not reflect neutrons back into the core but absorb them. Choice C is incorrect as the moderation of neutron velocity is typically achieved by other materials like a moderator (e.g., water, graphite) rather than control rods. Choice D is incorrect as control rods do not reflect neutrons or moderate neutron velocity, making it an incorrect option.
