1. What is the name of the condition characterized by swelling caused by a buildup of lymph fluid?

• A. Anemia
• B. Edema
• C. Hypertension
• D. Diabetes

Correct answer: B

Rationale: Edema is the condition characterized by swelling caused by a buildup of lymph fluid. It occurs when excess fluid is trapped in the body's tissues. Anemia (A) is a condition characterized by a lack of healthy red blood cells, leading to a reduced ability to carry oxygen in the blood. Hypertension (C) is high blood pressure, a condition where the force of the blood against the artery walls is too high. Diabetes (D) is a condition characterized by high blood sugar levels, either due to insufficient insulin production or the body's resistance to insulin, leading to various complications.

2. Urinary system health can be maintained through various lifestyle practices. Which of the following is NOT recommended for optimal urinary system health?

• A. Limiting high-sodium foods in the diet
• B. Consuming adequate amounts of cranberry juice
• C. Holding urine in the bladder for long periods
• D. Getting regular moderate-intensity exercise

Correct answer: C

Rationale: Holding urine in the bladder for long periods is not recommended for optimal urinary system health. It can increase the risk of urinary tract infections and other bladder-related issues. When urine is held for a long time, bacteria have more time to multiply in the bladder, leading to infections. Additionally, holding urine for prolonged periods can also contribute to bladder distension, which may affect bladder function over time. Therefore, it is crucial to empty the bladder regularly to maintain good urinary system health. Limiting high-sodium foods helps reduce the risk of kidney stones and high blood pressure, while consuming cranberry juice may help prevent urinary tract infections by interfering with the adhesion of bacteria to the bladder walls. Regular moderate-intensity exercise promotes overall health, including maintaining a healthy weight and reducing the risk of chronic conditions that can impact the urinary system.

3. Which of the following best defines the anatomical term medial?

• A. Being face down
• B. On the front of the body or limb
• C. Near to the midline of the body
• D. Above or on top of the lungs

Correct answer: C

Rationale: The correct definition of the anatomical term 'medial' is being close or near to the midline of the body. This term describes a position closer to the center or midline of the body, opposite to 'lateral' which refers to a position further away from the midline. Choice A, 'Being face down,' is incorrect as it describes the anatomical term 'prone.' Choice B, 'On the front of the body or limb,' is incorrect as it describes the anatomical term 'anterior.' Choice D, 'Above or on top of the lungs,' is incorrect as it does not relate to the term 'medial.'

4. Which part of the brain is responsible for controlling involuntary actions like breathing and heart rate?

• A. Cerebellum
• B. Medulla oblongata
• C. Cerebrum
• D. Thalamus

Correct answer: B

Rationale: The correct answer is the Medulla oblongata. This region of the brain is located in the brainstem and is responsible for controlling vital autonomic functions such as breathing, heart rate, and blood pressure. The Cerebellum (Choice A) is primarily involved in coordination and balance. The Cerebrum (Choice C) is responsible for higher brain functions like thinking and voluntary muscle movement. The Thalamus (Choice D) acts as a relay station for sensory information but is not primarily responsible for controlling involuntary actions like breathing and heart rate.

5. Which of the following is a weak acid commonly found in citrus fruits?

• A. Sulfuric acid (H₂SO₄)
• B. Hydrochloric acid (HCl)
• C. Citric acid
• D. Nitric acid (HNO₃)

Correct answer: C

Rationale: Citric acid is a weak acid commonly found in citrus fruits like lemons, oranges, and limes. It is responsible for the sour taste in these fruits. Sulfuric acid (option A), hydrochloric acid (option B), and nitric acid (option D) are all strong acids that are typically used in laboratory settings and industrial processes, not naturally found in citrus fruits. Therefore, the correct answer is option C.
