1. Choose the meaning of the word intact in the following sentence: 'The capsule remains intact even when placed in water.'

• A. Viable
• B. Operational
• C. Tinted
• D. Whole

Correct answer: D

Rationale: In this sentence, the word 'intact' is synonymous with 'whole,' meaning that the capsule remains undamaged or complete even when placed in water. Choices A, B, and C are incorrect. 'Viable' means capable of working successfully, 'operational' means in working order, and 'tinted' means slightly colored.

2. Which hormone regulates blood sugar levels?

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

Correct answer: A

Rationale: Insulin is the hormone that regulates blood sugar levels by promoting the uptake of glucose into cells. It is produced by the pancreas and helps to lower blood sugar levels when they are too high. Glucagon, on the other hand, works in opposition to insulin by raising blood sugar levels when they are too low. Cortisol and thyroxine play different roles in the body and are not primarily responsible for regulating blood sugar levels.

3. If a patient’s condition is upgraded, he is ___________.

• A. getting worse
• B. improving in status
• C. released from the hospital
• D. approved for surgery

Correct answer: B

Rationale: When a patient's condition is upgraded, it means that there has been an improvement in their medical status. This change usually indicates that the patient's health is improving or that they are responding well to treatment. Option A, 'getting worse,' is incorrect as an upgrade signifies a positive change. Option C, 'released from the hospital,' does not directly relate to an upgrade in the patient's condition. Option D, 'approved for surgery,' is unrelated to the patient's current medical status and the concept of an upgrade.

4. Which organ system is primarily responsible for preventing water loss?

• A. The nervous system
• B. The integumentary system
• C. The lymphatic system
• D. The urinary system

Correct answer: B

Rationale: The correct answer is B: The integumentary system. The integumentary system, which includes the skin, is primarily responsible for preventing water loss from the body. The skin acts as a barrier that helps regulate moisture and prevent excessive water loss through a process known as transepidermal water loss. The nervous system (choice A) is responsible for transmitting signals throughout the body, the lymphatic system (choice C) is responsible for the immune response and fluid balance, and the urinary system (choice D) is responsible for filtering blood and producing urine, but they do not primarily prevent water loss like the integumentary system.

5. Convert 2 teaspoons to milliliters.

• A. 4.3 milliliters
• B. 9 milliliters
• C. 9.86 milliliters
• D. 4 milliliters

Correct answer: C

Rationale: To convert teaspoons to milliliters, we use the conversion factor of 1 teaspoon = approximately 4.93 milliliters. Multiplying 2 teaspoons by 4.93 gives us 9.86 milliliters. Therefore, the correct answer is 9.86 milliliters. Choice A (4.3 milliliters) is incorrect as it doesn't align with the conversion factor. Choice B (9 milliliters) is incorrect because it doesn't consider the precise conversion factor. Choice D (4 milliliters) is incorrect as it doesn't account for the accurate conversion from teaspoons to milliliters.
