1. Which condition can lead to blood clots and stroke?

• A. Aneurysm
• B. Arrhythmia
• C. Asthma
• D. Hypertension

Correct answer: D

Rationale: Hypertension is the correct answer. Hypertension can cause damage to blood vessels, increasing the risk of blood clots forming, which can potentially lead to a stroke. Aneurysm is a localized, abnormal dilation of a blood vessel that can lead to complications but does not directly cause blood clots and strokes. Arrhythmia refers to irregular heart rhythms and is not directly linked to the formation of blood clots. Asthma is a chronic respiratory condition and does not typically lead to blood clots and strokes.

2. Which of the following is NOT a function of the endocrine system?

• A. Regulating growth and development
• B. Maintaining blood sugar levels
• C. Controlling mood and emotions
• D. Facilitating digestion through muscle contractions

Correct answer: D

Rationale: The endocrine system is responsible for producing hormones that regulate various bodily functions such as growth, metabolism, mood, and more. Facilitating digestion through muscle contractions is primarily the role of the muscular and nervous systems, not the endocrine system. Therefore, option D is the correct answer as it does not align with the functions typically attributed to the endocrine system. Choices A, B, and C are functions that are indeed associated with the endocrine system, making them incorrect answers in the context of this question.

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

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

Correct answer: C

Rationale: Conductivity is the correct term used to describe the ability of a substance to conduct electricity. Reactivity is the measure of a substance's tendency to undergo chemical reactions. Density refers to the mass per unit volume of a substance, while viscosity is a measure of a fluid's resistance to flow. In the context of conducting electricity, conductivity is the most appropriate term as it directly relates to the substance's electrical conductive properties.

4. Following successful heart transplant surgery, the patient's body will need to take medications to:

• A. Suppress the immune system and prevent rejection of the new heart.
• B. Reduce overall blood pressure.
• C. Dissolve any remaining blood clots.
• D. Stimulate the growth of new heart tissue.

Correct answer: A

Rationale: After heart transplant surgery, the patient's body will need to take medications to suppress the immune system and prevent rejection of the new heart. This is essential to ensure that the body does not identify the transplanted heart as a foreign entity and mount an immune response against it, which could lead to transplant rejection and failure. Choices B, C, and D are incorrect because post-heart transplant medications primarily focus on preventing rejection by suppressing the immune system, rather than reducing blood pressure, dissolving blood clots, or stimulating the growth of new heart tissue.

5. Which of the following terms describes the enlargement of an organ or tissue?

• A. Dystrophy
• B. Atrophy
• C. Hypertrophy
• D. Eutrophy

Correct answer: C

Rationale: Hypertrophy refers to the enlargement of an organ or tissue, typically due to an increase in the size of individual cells. This can occur in response to increased workload, hormonal stimulation, or other factors. On the other hand, dystrophy refers to the degeneration and deterioration of tissue, atrophy describes the decrease in the size of an organ or tissue, and eutrophy denotes a state of normal nutrition or growth. Therefore, the correct answer is 'Hypertrophy' as it specifically relates to the increase in size or volume of an organ or tissue.
