Nursing Elites

1. After discussing the possible effects of the low patient satisfaction rate, the staff started to list

• A. Collaboration
• B. Majority rule
• C. Dominance
• D. Compromise

Correct answer: B

Rationale: The correct answer is B: 'Majority rule.' In this scenario, the staff is likely listing potential solutions or actions based on the opinion or agreement of the majority. Collaboration (A) involves working together towards a common goal, while Dominance (C) implies one person or group having control. Compromise (D) suggests finding a middle ground between different viewpoints. Majority rule best fits the situation where a decision or list of actions is being determined by what most people agree on, which is a common approach in group decision-making processes.

2. What type of energy does a stretched rubber band possess?

• A. Kinetic energy
• B. Potential energy
• C. Thermal energy
• D. Mechanical energy

Correct answer:

Rationale: When a rubber band is stretched, it stores potential energy due to its position or state.

3. What enzyme plays a crucial role in DNA replication during the S phase of interphase?

• A. Helicase
• B. DNA polymerase
• C. Ligase
• D. Topoisomerase

Correct answer: B

Rationale: Rationale: During the S phase of interphase, DNA replication occurs. DNA polymerase is the enzyme responsible for synthesizing new DNA strands by adding nucleotides in a complementary fashion to the template strand. It plays a crucial role in replicating the entire genome accurately. Helicase unwinds the double-stranded DNA, topoisomerase relieves the tension in the DNA strands, and ligase joins the Okazaki fragments on the lagging strand. However, DNA polymerase is the enzyme directly involved in the synthesis of new DNA strands during replication.

4. A light ray travels from air (refractive index 1.00) into water (refractive index 1.33). What happens to its speed and direction?

• A. Speed increases, direction bends towards the normal.
• B. Speed increases, direction bends away from the normal.
• C. Speed decreases, direction bends towards the normal.
• D. Speed and direction remain unchanged.

Correct answer: A

Rationale: Due to the change in refractive index, the light ray bends towards the normal (water) as it slows down upon entering the denser medium.

5. What is the waste product of protein digestion?

• A. Glucose
• B. Amino acids
• C. Fatty acids
• D. Ammonia

Correct answer: D

Rationale: Rationale: Protein digestion involves breaking down proteins into their constituent amino acids. During this process, the waste product produced is ammonia. Ammonia is a toxic compound that needs to be converted into urea in the liver and then excreted by the kidneys in the form of urine. Glucose is a product of carbohydrate digestion, amino acids are the building blocks of proteins, and fatty acids are the end products of fat digestion.

6. The muscular chamber of the heart that receives blood from the body and pumps it to the lungs is the:

• A. Right atrium
• B. Left atrium
• C. Right ventricle
• D. Left ventricle

Correct answer: C

Rationale: The correct answer is C: Right ventricle. The right ventricle receives deoxygenated blood from the body and pumps it to the lungs for oxygenation. The right atrium receives deoxygenated blood from the body and passes it to the right ventricle. The left atrium receives oxygenated blood from the lungs and passes it to the left ventricle. The left ventricle then pumps oxygenated blood to the rest of the body. Understanding the flow of blood through the heart chambers is essential for grasping the functions of each chamber in the circulatory system.
