Nursing Leadership and Management

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

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. Diabetic nephropathy, a complication of diabetes, affects the:

Correct answer: D

Rationale: The correct answer is D: Nephrons. Diabetic nephropathy is a type of kidney disease that occurs as a complication of diabetes. It specifically affects the nephrons, which are the functional units of the kidneys responsible for filtering waste and excess fluids from the blood to produce urine. Damage to the nephrons can lead to kidney failure and other serious complications in individuals with diabetes. Therefore, understanding the impact of diabetes on the nephrons is crucial for managing diabetic nephropathy effectively.

3. The thymus gland, crucial for immune system development, is located in the:

Correct answer: A

Rationale: The thymus gland, an essential organ for immune system development, is located in the chest region, specifically in the upper part of the chest behind the breastbone. It plays a vital role in the maturation of T-cells, a type of white blood cell crucial for immune responses. The thymus gland is part of the lymphatic system and is most active during childhood and adolescence, gradually decreasing in size and function with age. Its location in the chest allows it to interact closely with other immune system components in the body, making it a key player in maintaining overall immune health.

4. Which of the following structures is responsible for preventing the backflow of blood from the left ventricle into the left atrium?

Correct answer: D

Rationale: The correct answer is D, the mitral valve. The mitral valve, also known as the bicuspid valve, is located between the left atrium and the left ventricle. Its main function is to prevent the backflow of blood from the left ventricle into the left atrium during ventricular contraction. The aortic valve (A) is responsible for preventing the backflow of blood from the aorta into the left ventricle, the pulmonary valve (B) prevents backflow from the pulmonary artery into the right ventricle, and the tricuspid valve (C) prevents backflow from the right ventricle into the right atrium. Therefore, the mitral valve is specifically responsible for preventing backflow in the left side of the heart, making it the correct answer in this case.

5. Which of the following describes a vector quantity?

Correct answer: d

Rationale: Velocity is a vector quantity as it includes both magnitude (speed) and direction.

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

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.
