Nursing Elites

1. She wants to ensure that every task is carried out as planned. Which of the following tasks is

• A. Instructing the members of the standards committee to prepare policies
• B. Reviewing the existing policies of the hospital
• C. Evaluating the credentials of all nursing staff
• D. Checking if activities conform to schedule

Correct answer: C

Rationale: The correct answer is C because evaluating the credentials of all nursing staff is essential to ensuring that the right individuals are in place to carry out tasks effectively. This task directly contributes to maintaining a high standard of performance and ensuring that the team is qualified for their roles. In contrast, the other options focus on policies, reviews, and schedules, which are important but do not directly address the qualifications and capabilities of the staff responsible for task execution.

2. The athlete ran the race in record time. Which word is the present participle of the verb "run"?

• A. ran
• B. runs
• C. running
• D. runner

Correct answer: C

Rationale: The present participle form of a verb describes an ongoing action.

3. The spleen, a large lymphatic organ, is located in the:

• A. Chest
• B. Abdomen
• C. Pelvis
• D. Head and neck

Correct answer: B

Rationale: The correct answer is B: Abdomen. The spleen, a large lymphatic organ, is located in the upper left part of the abdomen, under the ribcage and above the stomach. It plays a crucial role in filtering and purifying the blood, removing old or damaged blood cells, and storing blood. The spleen is not located in the chest, pelvis, or head and neck. Understanding the anatomical location of organs is essential for medical professionals to accurately diagnose and treat patients.

4. What is the term for a genetic disorder caused by a mutation in a mitochondrial gene?

• A. Autosomal dominant disorder
• B. Autosomal recessive disorder
• C. Sex-linked disorder
• D. Mitochondrial disorder

Correct answer: D

Rationale: Rationale: A) Autosomal dominant disorder: This type of genetic disorder is caused by a mutation in one copy of an autosomal gene. It is not related to mitochondrial gene mutations. B) Autosomal recessive disorder: This type of genetic disorder is caused by mutations in both copies of an autosomal gene. It is not related to mitochondrial gene mutations. C) Sex-linked disorder: This type of genetic disorder is caused by mutations in genes located on the sex chromosomes (X or Y). It is not related to mitochondrial gene mutations. D) Mitochondrial disorder: Mitochondrial disorders are genetic disorders caused by mutations in genes located in the mitochondria, the energy-producing structures within cells. These disorders are inherited maternally and can affect various organs and systems in the body due to the role of mitochondria in energy production.

5. Which of the following is NOT a function of the nervous system?

• A. Detecting touch
• B. Regulating body temperature
• C. Producing insulin
• D. Controlling muscle movement

Correct answer: C

Rationale: The correct answer is C: 'Producing insulin.' The nervous system is responsible for detecting touch (option A), regulating body temperature (option B), and controlling muscle movement (option D). Insulin production is actually regulated by the endocrine system, specifically the pancreas. Insulin helps regulate blood sugar levels, which is not a function of the nervous system. It is important to differentiate between the roles of the nervous system and the endocrine system in maintaining bodily functions.

6. Elements tend to gain or lose electrons to achieve stable electron configurations like those of noble gases. Their group number often indicates the number of electrons gained/lost and the resulting ionic charge, providing a good starting point for prediction.

• A. Ionic bonds involve electron sharing, while metallic bonds involve electron transfer
• B. Ionic bonds are weak and directional, while metallic bonds are strong and non-directional
• C. Ionic bonds exist between metals and non-metals, while metallic bonds exist only between metals
• D. Ionic bonds form discrete molecules, while metallic bonds form extended structures

Correct answer: D

Rationale: Ionic bonds involve complete electron transfer between atoms, creating strong, non-directional electrostatic attraction. Metallic bonds involve a delocalized "sea" of electrons shared across all metal atoms, resulting in a strong, extended structure.
