1. Which adjective best describes the following setting: "A lone cabin stood nestled amongst towering pines, smoke curling from its chimney into the crisp mountain air."

• A. Bland
• B. Urban
• C. Idyllic
• D. Sterile

Correct answer: C

Rationale: "Idyllic" captures the peaceful and picturesque nature of the setting.

2. The statement, “The Good Shepherd Medical Center aims to provide patient-centered care in

• A. Vision
• B. Goal
• C. Philosophy
• D. Mission

Correct answer: A

Rationale: The correct answer is A: "Vision." A vision statement describes the desired future state or long-term goal of an organization. It outlines the aspirations and purpose of the organization, such as providing patient-centered care in this case. Vision statements are forward-looking and inspirational, guiding the organization towards achieving its ultimate objectives. In contrast, a goal is a specific, measurable, and achievable target within a set timeframe. A philosophy is a set of beliefs or guiding principles, while a mission statement defines the organization's core purpose and focus. Therefore, the statement about providing patient-centered care aligns with the concept of a vision statement.

3. Square: A garden bed has a side length of 8 meters. What is its perimeter?

• A. 16m
• B. 24m
• C. 32m
• D. 64m

Correct answer: D

Rationale: Since all sides are equal, multiply the side length by 4: perimeter = 4 * side length = 4 * 8m = 32m.

4. The pancreas secretes digestive enzymes into the small intestine. What enzyme breaks down proteins into amino acids?

• A. Pepsin
• B. Lipase
• C. Amylase
• D. Trypsin

Correct answer: D

Rationale: The correct answer is D: Trypsin. Trypsin is an enzyme produced by the pancreas and secreted into the small intestine where it plays a key role in breaking down proteins into smaller peptides and amino acids. Pepsin is produced in the stomach and specifically acts on protein, not in the small intestine. Lipase is an enzyme that breaks down fats, not proteins. Amylase is an enzyme that breaks down carbohydrates, not proteins. Therefore, Trypsin is the enzyme responsible for breaking down proteins into amino acids in the small intestine.

5. Which hormone, produced by the thyroid gland, plays a key role in regulating calcium levels in the blood by promoting calcium release from bones and increasing calcium reabsorption in the kidneys?

• A. Calcitonin
• B. Parathyroid hormone (PTH)
• C. Thyroxine
• D. Insulin

Correct answer: b

Rationale: The correct answer is B: Parathyroid hormone (PTH). PTH is produced by the parathyroid glands, not the thyroid gland. PTH plays a crucial role in regulating calcium levels in the blood by promoting calcium release from bones and increasing calcium reabsorption in the kidneys. This hormone acts in opposition to calcitonin, which is produced by the thyroid gland and works to lower blood calcium levels by promoting calcium deposition into bones. Thyroxine (C) is a thyroid hormone that regulates metabolism, not calcium levels. Insulin (D) is a hormone produced by the pancreas that regulates blood sugar levels, not calcium levels.

6. Fluorescent microscopy utilizes which property of certain molecules to create a visible image?

• A. Staining properties
• B. Light absorption
• C. Fluorescence emission
• D. Refraction

Correct answer: C

Rationale: Rationale: Fluorescent microscopy relies on the property of certain molecules to fluoresce when exposed to specific wavelengths of light. When these molecules absorb light energy, they become excited and then emit light at a longer wavelength, producing a visible image. This emitted light is what is used to create the image in fluorescent microscopy, making option C, fluorescence emission, the correct answer. Staining properties (option A) are used to enhance contrast in microscopy but are not the primary mechanism in fluorescent microscopy. Light absorption (option B) is involved in the excitation of fluorescent molecules but is not the property used to create the visible image. Refraction (option D) is the bending of light as it passes through different mediums and is not the property utilized in fluorescent microscopy.
