Nursing Elites

1. Katherine is a young Unit Manager of the Pediatric Ward. Most of her staff nurses are senior

• A. Identify the source of the conflict and understand the points of friction
• B. Disregard what she feels and continue to work independently
• C. Seek help from the Director of Nursing
• D. Quit her job and look for another employment.

Correct answer: C

Rationale: The correct answer is C: Seek help from the Director of Nursing. As a young Unit Manager managing a team of senior staff nurses, Katherine may face challenges in leading and gaining the respect of her team due to the age and experience gap. Seeking help from the Director of Nursing can provide her with guidance, mentorship, and support in navigating these challenges. It is important for Katherine to communicate openly about any conflicts or issues she may be facing in order to address them effectively and maintain a positive work environment. Quitting her job (option D) should be considered as a last resort after exhausting all other possible solutions.

2. What happens to the density of a substance if its mass increases while its volume remains constant?

• A. Density increases
• B. Density decreases
• C. Density remains constant
• D. Density becomes zero

Correct answer: a

Rationale: Density is the ratio of mass to volume. If the mass increases while the volume remains constant, the density will increase as there is more mass in the same volume.

3. Which type of white blood cell directly attacks and destroys pathogens like bacteria and viruses?

• A. Neutrophils
• B. Lymphocytes
• C. Monocytes
• D. Eosinophils

Correct answer: A

Rationale: The correct answer is A: Neutrophils. Neutrophils are a type of white blood cell that plays a crucial role in the innate immune response by directly attacking and destroying pathogens like bacteria and viruses. They are the most abundant type of white blood cell and are known for their rapid response to infections. Neutrophils work by engulfing and digesting pathogens through a process called phagocytosis. Lymphocytes (option B) are involved in adaptive immunity, producing antibodies and coordinating immune responses. Monocytes (option C) differentiate into macrophages and dendritic cells, playing a role in phagocytosis and antigen presentation. Eosinophils (option D) are primarily involved in combating parasitic infections and allergic reactions, not directly attacking bacteria and viruses.

4. The ball-and-socket joint, which allows for wide range of motion, is found in the connection between:

• A. Upper arm and shoulder blade (scapula)
• B. Collarbone (clavicle) and breastbone (sternum)
• C. Two vertebrae in the spine
• D. Ribs and sternum

Correct answer: A

Rationale: The correct answer is A: 'Upper arm and shoulder blade (scapula).' The ball-and-socket joint is found in the connection between the humerus (upper arm bone) and the scapula (shoulder blade). This joint allows for a wide range of motion, including flexion, extension, abduction, adduction, and rotation. The collarbone (clavicle) and breastbone (sternum) are connected by a cartilaginous joint, not a ball-and-socket joint. Two vertebrae in the spine are connected by facet joints, and the ribs and sternum are connected by cartilaginous joints and the costovertebral joints. Therefore, the ball-and-socket joint is uniquely found in the connection between the upper arm and the shoulder blade, allowing for the shoulder's impressive range of motion.

5. Antidiuretic hormone (ADH) helps the kidneys regulate:

• A. Acid-base balance
• B. Blood pressure
• C. Urine output by controlling water reabsorption
• D. All of the above

Correct answer: C

Rationale: The correct answer is C: 'Urine output by controlling water reabsorption.' Antidiuretic hormone (ADH) is released by the pituitary gland and acts on the kidneys to regulate water reabsorption. When ADH levels are high, the kidneys reabsorb more water, leading to concentrated urine and decreased urine output. This helps maintain the body's water balance and prevent dehydration. While ADH indirectly influences blood pressure by regulating blood volume, its primary function is to control water balance, not acid-base balance. Therefore, the correct answer is C.

6. What literary device is used in the line "The sea whispered secrets to the shore"?

• A. Alliteration
• B. Personification
• C. Onomatopoeia
• D. Hyperbole

Correct answer: B

Rationale: The sentence gives human qualities to the sea, like whispering, creating personification.
