Anatomy

1. Which of the following is NOT a risk factor for developing atherosclerosis?

Correct answer: C

Rationale: Regular physical activity is NOT a risk factor for developing atherosclerosis. In fact, engaging in regular physical activity can help reduce the risk of developing atherosclerosis by improving cardiovascular health, lowering blood pressure, and reducing LDL cholesterol levels. High blood pressure, high levels of LDL cholesterol, and smoking are all known risk factors for atherosclerosis. High blood pressure can damage blood vessels, making them more susceptible to plaque buildup. High levels of LDL cholesterol can lead to the accumulation of plaque in the arteries, narrowing the passageways and increasing the risk of atherosclerosis. Smoking is harmful to blood vessels, promoting inflammation and the formation of plaque. Therefore, regular physical activity is actually a protective factor against atherosclerosis rather than a risk factor.

2. Which of the following is the main function of the pancreas?

Correct answer: C

Rationale: Rationale: The pancreas is a vital organ in the digestive system that produces digestive enzymes such as amylase, lipase, and proteases. These enzymes are released into the small intestine to help break down carbohydrates, fats, and proteins in food, aiding in the digestion and absorption of nutrients. Options A and B are incorrect because the pancreas is not involved in storing or absorbing nutrients. Option D is partially correct as the pancreas also plays a role in regulating blood sugar levels by producing insulin and glucagon, but its primary function is to produce digestive enzymes.

3. Which of the following is a redox reaction?

Correct answer: b

Rationale: The oxidation state of Zn changes from 0 to +2, indicating a redox reaction.

4. When is work done by a force on an object?

Correct answer: A

Rationale: Work is done by a force on an object when the object moves in the direction of the force. If the object moves perpendicular to the force, no work is done, as the force does not contribute to the displacement of the object. Similarly, if the object moves against the force, work is done because the force is causing the displacement. The vertical movement of the object does not determine whether work is done; it is the direction of the force relative to the object's displacement that matters. The duration of the force application does not affect whether work is done; as long as the force causes the object to move in its direction, work is being done.

5. Electrons occupy specific energy levels around the nucleus, but not in fixed orbits. This concept is captured by the:

Correct answer: B

Rationale: Quantum mechanical model. Unlike the Bohr model with its defined electron paths, the quantum mechanical model uses probability distributions to describe electron locations within energy levels.

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

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.
