1. Most water leaves the body by way of the:

• A. Lungs
• B. Intestines
• C. Skin
• D. Kidneys

Correct answer: D

Rationale: Most water leaves the body through the kidneys. The kidneys play a crucial role in filtering waste and excess substances from the blood to form urine, which is then excreted out of the body. Choices A, B, and C are incorrect because while a small amount of water can be lost through respiration, feces, and sweating, the primary organ responsible for regulating water balance and excretion is the kidneys.

2. What is a cavity containing pus surrounded by inflamed tissue?

• A. Cellulitis.
• B. An abscess.
• C. Extravasation.
• D. An adhesion.

Correct answer: B

Rationale: An abscess is defined as a cavity containing pus surrounded by inflamed tissue. Cellulitis is a bacterial skin infection causing redness and swelling, not a cavity. Extravasation is the leakage of fluid from a vessel into surrounding tissues, not a cavity. An adhesion is a band of scar-like tissue that binds two parts together, not a cavity containing pus and inflamed tissue.

3. What percentage of term newborns have a congenital heart disease due to environmental risk factors such as maternal alcoholism or drug ingestion?

• A. 2% to 4%
• B. 10% to 20%
• C. 5% to 10%
• D. 7% to 9%

Correct answer: A

Rationale: The correct answer is A: 2% to 4%. According to research, 2% to 4% of term newborns have congenital heart disease due to environmental risk factors such as maternal alcoholism or drug ingestion. Choices B, C, and D provide percentages that are higher than the actual prevalence of congenital heart disease in newborns caused by environmental factors, making them incorrect.

4. Which of the following joints normally allows 360-degree circumflexion?

• A. The knee
• B. The shoulder
• C. The elbow
• D. The fingertips

Correct answer: B

Rationale: The correct answer is B: The shoulder. The shoulder joint is a ball-and-socket joint that allows for a wide range of motion, including 360-degree circumflexion. This joint provides flexibility and mobility in various directions. Choice A, the knee joint, primarily allows flexion and extension but does not have a 360-degree circumflexion. Choice C, the elbow joint, is a hinge joint that permits flexion and extension but not circumflexion. Choice D, the fingertips, do not form a specific joint that allows circumflexion; rather, they have joints that enable bending and straightening movements.

5. Which patient is at greatest risk for papilledema?

• A. An elderly patient with cataracts and macular degeneration
• B. A male patient with hypothyroidism
• C. A male patient with hyperthyroidism
• D. An adolescent with a closed head injury

Correct answer: D

Rationale: An adolescent with a closed head injury is at the highest risk for papilledema due to increased intracranial pressure. Papilledema is often a consequence of elevated intracranial pressure, which can occur in conditions like head trauma. Choices A, B, and C do not directly correlate with an increased risk of papilledema compared to a closed head injury, which is more likely to lead to elevated intracranial pressure and subsequent papilledema.
