Nursing Elites

1. Which property of a wave determines its loudness in sound waves?

• A. Amplitude
• B. Wavelength
• C. Frequency
• D. Speed

Correct answer: a

Rationale: Amplitude in sound waves relates to the loudness or intensity of the sound.

2. Which of the following is the positively charged subatomic particle found in the nucleus of an atom?

• A. Electron
• B. Proton
• C. Neutron
• D. Quark

Correct answer: B

Rationale: Protons are positively charged subatomic particles found in the nucleus of an atom. They have a mass of approximately 1 atomic mass unit (amu) and a charge of +1. The number of protons in an atom's nucleus determines the atomic number of the element, which is a unique identifier for each element.

3. Aubrey thinks about primary nursing as a system to deliver care. Which of the following

• A. Collaborates with the physician
• B. Provides care to a group of patients together with a group of nurses
• C. Provides care for 5-6 patients during their hospital stay.
• D. Performs comprehensive initial assessment

Correct answer: D

Rationale: Primary nursing is a care delivery system where one nurse is responsible for the total nursing care needs of a group of patients throughout their hospital stay. This includes performing comprehensive initial assessments, developing care plans, coordinating with other healthcare team members, and providing direct patient care. Option D is the correct answer as it aligns with the core principles of primary nursing, emphasizing the nurse's role in conducting thorough assessments to ensure individualized and holistic care for each patient in their caseload. Options A, B, and C do not accurately reflect the key components of primary nursing, making them incorrect choices.

4. When making a dilution, you...

• A. Add more solute to a concentrated solution
• B. Change the temperature of the solution
• C. Decrease the concentration of a solution
• D. All of the above

Correct answer: C

Rationale: The correct answer is C: 'Decrease the concentration of a solution.' When making a dilution, you decrease the concentration of a solution by adding more solvent, not solute. Adding more solute to a concentrated solution would increase the concentration, not dilute it. Changing the temperature of the solution does not directly relate to dilution. Therefore, the only correct statement related to the process of making a dilution is that you decrease the concentration of the solution by adding more solvent, making option C the correct answer.

5. What is the muscular sac in the female body that nourishes and protects a developing fetus during pregnancy?

• A. Ovary
• B. Fallopian tube
• C. Uterus
• D. Vagina

Correct answer: C

Rationale: The correct answer is C: Uterus. The uterus, also known as the womb, is a muscular sac in the female reproductive system where a fertilized egg implants and develops into a fetus during pregnancy. It provides nourishment, support, and protection to the developing fetus until birth. The ovaries produce eggs, the fallopian tubes transport eggs to the uterus, and the vagina is the birth canal and the organ of sexual intercourse, but the uterus is specifically responsible for nurturing and protecting the developing fetus.

6. A ball is thrown upwards. Which of the following statements is TRUE about its potential energy and kinetic energy at the peak of its trajectory?

• A. Both potential and kinetic energy are zero.
• B. Potential energy is maximum and kinetic energy is minimum.
• C. Potential energy is minimum and kinetic energy is maximum.
• D. Both potential and kinetic energy remain constant.

Correct answer: B

Rationale: At the peak, the ball momentarily stops moving, minimizing kinetic energy. However, it's still at its highest point, maximizing its potential energy due to gravity.
