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. A nurse administers 150mg of medication every 4 hours. How many milligrams will the patient receive in 24 hours?

• A. 300mg
• B. 600mg
• C. 750mg
• D. 900mg

Correct answer: D

Rationale: Rationale: - The patient receives 150mg of medication every 4 hours. - To calculate how many milligrams the patient will receive in 24 hours, we need to determine how many times the medication is administered in 24 hours. - Since the medication is administered every 4 hours, there are 24 hours in a day, so the medication will be administered 24 / 4 = 6 times in 24 hours. - Therefore, the total amount of medication the patient will receive in 24 hours is 150mg x 6 = 900mg.

3. What phenomenon occurs when a wave encounters a change in medium causing a change in its speed and direction?

• A. Refraction
• B. Reflection
• C. Diffraction
• D. Interference

Correct answer: a

Rationale: Refraction happens when a wave changes its speed and direction due to encountering a change in medium.

4. What is the process by which a population gradually loses genetic variation?

• A. Founder effect
• B. Bottleneck effect
• C. Gene flow
• D. Speciation

Correct answer: B

Rationale: Rationale: A) Founder effect: This occurs when a small group of individuals establishes a new population, leading to a loss of genetic variation compared to the original population. It does not necessarily result in a gradual loss of genetic variation in an existing population. B) Bottleneck effect: This process occurs when a population is drastically reduced in size, leading to a significant loss of genetic variation due to the limited number of individuals contributing to the gene pool. The reduced genetic diversity can have long-term effects on the population's ability to adapt to environmental changes. C) Gene flow: This refers to the movement of genes between populations, which can introduce new genetic variation and prevent populations from diverging. Gene flow does not lead to a gradual loss of genetic variation within a population. D) Speciation: This is the process by which new species evolve from existing species, often involving the accumulation of genetic differences that l

5. In what way does spindle fiber dynamics and microtubule attachment regulate cell cycle checkpoints?

• A. Misaligned chromosomes fail to attach to microtubules, triggering a delay in anaphase onset.
• B. The presence of unattached kinetochores on the centromeres sends a signal to pause cell cycle progression.
• C. Microtubule instability and rapid depolymerization lead to the activation of checkpoint proteins.
• D. All of the above.

Correct answer: D

Rationale: Rationale: A) Misaligned chromosomes fail to attach to microtubules, triggering a delay in anaphase onset: During cell division, proper attachment of chromosomes to spindle fibers is crucial for accurate segregation of genetic material. If chromosomes are not correctly attached to microtubules, it can lead to misalignment, which triggers a delay in anaphase onset. This delay allows the cell to correct any errors before proceeding with cell division. B) The presence of unattached kinetochores on the centromeres sends a signal to pause cell cycle progression: Kinetochores are protein structures located at the centromere of chromosomes and are responsible for attaching chromosomes to spindle fibers. When kinetochores are unattached or improperly attached to microtubules, it sends a signal to the cell to pause cell cycle progression. This pause allows the cell to ensure that all chromosomes are properly aligned before proceeding with cell division.

6. Which vitamin deficiency can lead to kidney stones?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin D
• D. Vitamin K

Correct answer: D

Rationale: The correct answer is D, Vitamin K. Vitamin K plays a role in blood clotting and bone health. A deficiency in Vitamin K can lead to an increased risk of kidney stones due to the improper regulation of calcium in the body. Calcium can accumulate in the kidneys and form stones if not properly managed. Vitamin K deficiency can disrupt the balance of calcium in the body, contributing to the development of kidney stones. Therefore, it is important to ensure an adequate intake of Vitamin K to prevent kidney stone formation.
