1. Enlargement of the thyroid, commonly known as a goiter, might be expected to affect ___________.

• A. swallowing
• B. insulin levels
• C. sleep
• D. digestion

Correct answer: A

Rationale: Enlargement of the thyroid, known as a goiter, can compress the nearby structures in the neck, including the esophagus. This compression can lead to symptoms such as difficulty swallowing (dysphagia) or a sensation of pressure in the throat. Therefore, an enlarged thyroid gland is expected to affect swallowing. Choices B, C, and D are incorrect because a goiter primarily affects structures in the neck due to its physical enlargement, rather than directly impacting insulin levels, sleep, or digestion.

2. In the human body, the ribs are ___________ to the lungs.

• A. medial
• B. superior
• C. anterior
• D. deep

Correct answer: C

Rationale: The correct answer is 'C: anterior.' The term 'anterior' refers to a position in front of or toward the front of the body. In this case, the ribs are positioned in front of the lungs when considering the anatomical position. The term 'medial' means toward the midline of the body, 'superior' means above or higher in position, and 'deep' refers to a position farther from the surface or external part. Therefore, the most appropriate choice is 'anterior' when describing the relationship between the ribs and the lungs.

3. Which hormone is involved in the regulation of water balance in the body?

• A. ADH
• B. Insulin
• C. Cortisol
• D. Thyroxine

Correct answer: A

Rationale: The correct answer is ADH (antidiuretic hormone), also known as vasopressin. ADH helps regulate water balance in the body by controlling the amount of water reabsorbed by the kidneys. When there is a need to conserve water, ADH levels increase, leading to more water reabsorption and concentration of urine. Insulin is involved in regulating blood sugar levels, not water balance. Cortisol is a stress hormone that helps regulate metabolism and immune response, not water balance. Thyroxine is a thyroid hormone that regulates metabolism, growth, and development, not water balance.

4. Which type of blood vessel carries oxygenated blood away from the heart?

• A. Veins
• B. Arteries
• C. Capillaries
• D. Lymphatic vessels

Correct answer: B

Rationale: Arteries are blood vessels that carry oxygenated blood away from the heart to supply tissues and organs with oxygen and nutrients. Veins carry deoxygenated blood back to the heart. Capillaries facilitate the exchange of nutrients and gases between the blood and tissues. Lymphatic vessels are part of the lymphatic system responsible for returning interstitial fluid to the bloodstream. Therefore, the correct answer is arteries as they carry oxygenated blood away from the heart.

5. What is a common finding in a whiplash injury?

• A. Cardiopulmonary issues
• B. Side-to-side spinal curvature
• C. Eventual herniation of discs
• D. Traumatic injury to ligaments

Correct answer: D

Rationale: A common finding in a whiplash injury is a traumatic injury to ligaments. Whiplash occurs due to sudden hyperextension and hyperflexion of the neck, leading to strain or tearing of ligaments in the neck. This can manifest as neck pain, stiffness, and limited range of motion. While other complications like cardiopulmonary problems, side-to-side spinal curvature, or eventual herniation of discs are not typically associated with whiplash injuries.
