1. Rectangle: A picture frame measures 15cm by 20cm. What is its perimeter?

• A. 30cm
• B. 55cm
• C. 65cm
• D. 75cm

Correct answer: C

Rationale: To find the perimeter of a rectangle, you add the lengths of all sides. The formula for the perimeter of a rectangle is 2 * (length + width). In this case, the length is 15cm and the width is 20cm. Therefore, the perimeter = 2 * (15cm + 20cm) = 65cm. Choice A (30cm), Choice B (55cm), and Choice D (75cm) are incorrect as they do not correctly calculate the perimeter of the given rectangle.

2. What is 2/3 of 60 + 1/5 of 75?

• A. 45
• B. 55
• C. 15
• D. 50

Correct answer: B

Rationale: To solve the expression, first calculate 2/3 of 60 by multiplying 60 by 2/3, which equals 40. Then, calculate 1/5 of 75 by multiplying 75 by 1/5, which equals 15. Finally, add these results together: 40 + 15 = 55. Therefore, the correct answer is 55. Choice A (45) is incorrect because it seems to be the sum of the two fractions, not their individual calculations. Choice C (15) is incorrect because it only represents 1/5 of 75. Choice D (50) is incorrect as it might be a miscalculation of the sum of the two fractions.

3. What does 'Compensatory' mean?

• A. Harmful
• B. Offsetting or making up for something
• C. Adding unnecessary work
• D. Hindering

Correct answer: B

Rationale: The term 'Compensatory' means offsetting or making up for something. In this context, it refers to the act of providing something in order to make up for a deficiency or loss. It is not related to being harmful, hindering, or adding unnecessary work. 'Harmful' (Choice A), 'Adding unnecessary work' (Choice C), and 'Hindering' (Choice D) are incorrect as they do not align with the meaning of 'Compensatory.'

4. 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.

5. Which hormone is involved in regulating the sleep-wake cycle?

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

Correct answer: B

Rationale: The correct answer is B: Melatonin. Melatonin, produced by the pineal gland, is the hormone involved in regulating the sleep-wake cycle. It plays a crucial role in signaling the body that it is time to sleep and is influenced by light exposure. Melatonin levels typically rise in the evening, promoting sleep, and decrease in the morning, helping in waking up. Choice A, Insulin, is involved in regulating blood sugar levels, not the sleep-wake cycle. Choice C, Cortisol, is a stress hormone that helps regulate metabolism and immune response but is not primarily involved in the sleep-wake cycle. Choice D, Thyroxine, is a hormone produced by the thyroid gland that regulates metabolism, growth, and development, but it is not directly involved in regulating the sleep-wake cycle.
