1. Which of the following statements is true regarding a supersaturated solution?

• A. It is unstable and tends to crystallize
• B. It contains less solute than it could dissolve
• C. It has a lower concentration than a saturated solution
• D. It is rarely encountered in everyday solutions

Correct answer: a

Rationale: Supersaturated solutions are unstable and tend to crystallize if disturbed. The other choices do not accurately describe supersaturated solutions.

2. Two objects with different masses collide. What happens to their momentum after the collision?

• A. Increases for both objects
• B. Decreases for both objects
• C. Remains the same for both objects
• D. Can increase for one and decrease for the other

Correct answer: C

Rationale: In an isolated system (no external forces), the total momentum

3. Which of the following is the best guarantee that the patient’s priority needs are met?

• A. Checking with the relative of the patient
• B. Preparing a nursing care plan in collaboration with the patient
• C. Consulting with the physician
• D. Coordinating with other members of the team

Correct answer: B

Rationale: Preparing a nursing care plan in collaboration with the patient is the best guarantee that the patient's priority needs are met because it involves actively involving the patient in their own care. This approach ensures that the patient's preferences, concerns, and priorities are taken into account when planning their care. Checking with the relative of the patient, consulting with the physician, and coordinating with other team members are important aspects of patient care, but collaborating with the patient directly ensures a patient-centered approach that addresses their individual needs and preferences.

• C. Cautiously pragmatic, recognizing its valuable potential while advocating for addressing its downsides.
• D. Indifferent and neutral, lacking any strong opinion on its role in education.

Correct answer: C

Rationale: The emphasis on both benefits and challenges suggests a balanced and pragmatic perspective, aligning with C.

5. Which hormone, produced by the pancreas, is involved in the regulation of blood sugar levels by inhibiting the release of insulin and promoting the release of glucose into the bloodstream?

• A. Insulin
• B. Glucagon
• C. Cortisol
• D. Somatostatin

Correct answer: D

Rationale: The correct answer is D: Somatostatin. Somatostatin is a hormone produced by the pancreas that plays a key role in regulating blood sugar levels. It inhibits the secretion of insulin, which helps prevent a further decrease in blood sugar levels. Additionally, somatostatin promotes the release of glucose into the bloodstream by inhibiting the release of other hormones that would lower blood sugar levels. This dual action of somatostatin helps maintain blood sugar within a normal range. While insulin is involved in lowering blood sugar levels by promoting glucose uptake, glucagon stimulates the release of glucose from storage to increase blood sugar levels. Cortisol is a steroid hormone produced by the adrenal glands that plays a role in stress response and metabolism, but it is not directly involved in regulating blood sugar levels.

6. The longest bone in the human body is the:

• A. Tibia
• B. Fibula
• C. Femur
• D. Humerus

Correct answer: C

Rationale: The correct answer is C: "Femur." The femur is the longest bone in the human body, located in the thigh region and connecting the hip to the knee. It plays a crucial role in supporting the body's weight and facilitating movement. The tibia and fibula are bones in the lower leg, while the humerus is a bone in the upper arm. Therefore, the femur is the correct answer for the longest bone in the human body.
