Nursing Elites

1. A patient needs to take 2 tablets for every 30 pounds of body weight. If they weigh 150 pounds, how many tablets should they take?

• A. 5
• B. 10
• C. 15
• D. 20

Correct answer: A

Rationale: Divide the patient's weight (150 pounds) by the ratio denominator (30 pounds/tablet) to get 5 tablets.

2. What is the product of the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH)?

• A. NaCl + H2O
• B. NaOH + HCl
• C. Na2Cl + H2O
• D. NaClO3 + H2

Correct answer: a

Rationale: The reaction between HCl and NaOH results in the formation of sodium chloride (NaCl) and water (H2O).

3. Photons, the basic unit of light, are:

• A. Charged particles
• B. Packets of energy with wave-particle duality
• C. Electromagnetic waves only
• D. Always absorbed by matter

Correct answer: B

Rationale: The correct answer is B: Packets of energy with wave-particle duality. Photons are the smallest discrete amount of electromagnetic radiation and exhibit both wave-like and particle-like properties. While photons do not have a charge, they do carry energy and momentum. This dual nature of photons is a fundamental concept in quantum mechanics. Photons can travel as both waves and particles, and their behavior is described by the wave-particle duality principle. Therefore, option B accurately describes the nature of photons as packets of energy with wave-particle duality.

4. Which type of nuclear force is responsible for holding protons and neutrons together in the nucleus of an atom?

• A. Electromagnetism
• B. Gravity
• C. Strong nuclear force
• D. Weak nuclear force

Correct answer: C

Rationale: The incredibly powerful, strong nuclear force overcomes the repulsive electrostatic force between protons, binding them together and stabilizing the nucleus.

5. What is the formula to calculate work?

• A. Work = Force × Distance
• B. Work = Mass × Velocity
• C. Work = Power × Time
• D. Work = Energy ÷ Time

Correct answer: a

Rationale: Work is calculated by multiplying force exerted on an object by the distance the object moves in the direction of the force.

6. Which of the following guidelines should be least considered in formulating objectives for

• A. Written nursing care plan
• B. Holistic approach
• C. Prescribed standards
• D. Staff preferences

Correct answer: D

Rationale: When formulating objectives for a written nursing care plan, staff preferences should be the least considered guideline. Objectives in a care plan should be based on the patient's needs, evidence-based practices, and prescribed standards of care to ensure quality and effective treatment. Staff preferences may introduce biased decisions that do not align with the best interests of the patient. It is crucial to prioritize holistic care, which considers all aspects of the patient's well-being, and adhere to prescribed standards to provide comprehensive and individualized care. By disregarding staff preferences and focusing on what is best for the patient, healthcare professionals can deliver optimal care that promotes patient outcomes and satisfaction.
