Nursing Elites

1. Locate the heart within the human body cavities.

• A. Dorsal cavity
• B. Ventral cavity
• C. Thoracic cavity
• D. Abdominal cavity

Correct answer: C

Rationale: Rationale: The heart is located within the thoracic cavity, specifically in the mediastinum, which is the central compartment of the thoracic cavity. The thoracic cavity is part of the ventral cavity, which also includes the abdominal cavity. The dorsal cavity refers to the posterior side of the body and does not contain the heart. The heart is situated in the thoracic cavity between the lungs and above the diaphragm, making option C the correct choice.

2. 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.

3. In the process of osmosis, the solvent moves from an area of...

• A. Low solute concentration to high solute concentration
• B. Hotter solution to colder solution
• C. Colder solution to hotter solution
• D. High solute concentration to low solute concentration

Correct answer: D

Rationale: In osmosis, solvent molecules move across a semi-permeable membrane from an area of low solute concentration to high solute concentration. This movement is driven by the desire to equalize the concentration of solutes on both sides of the membrane. As a result, option A is the correct answer because the solvent will naturally flow towards the area with a higher concentration of solutes in order to balance the concentrations on both sides of the membrane. Options B and C are incorrect as osmosis is not influenced by temperature differences. Option D is incorrect as the solvent does not move towards areas of high solute concentration in osmosis.

4. Which term describes the ability of a substance to conduct electricity?

• A. Reactivity
• B. Density
• C. Conductivity
• D. Viscosity

Correct answer: c

Rationale: Conductivity refers to a substance's ability to conduct electricity. Substances that conduct electricity well are known as conductors.

5. Which of the following functional groups is present in carboxylic acids?

• A. Carbonyl
• B. Hydroxyl
• C. Carboxyl
• D. Aldehyde

Correct answer: C

Rationale: Carboxylic acids contain the carboxyl functional group (-COOH). The other choices are associated with different functional groups.

6. A scientist observes a new species of plant with unusual leaves. They hypothesize that the leaves help capture more sunlight. Which observation would LEAST support this hypothesis?

• A. The plant grows in shady environments.
• B. The leaves have a large surface area.
• C. The leaves contain high levels of chlorophyll.
• D. The plant has shallow roots.

Correct answer: A

Rationale: If the plant thrives in shade, it suggests the leaves may have adapted for other purposes than maximizing sunlight capture.
