1. The formula for calculating ideal body weight (IBW) for men is IBW (kg) = 50 + 2.3 * (height in cm - 150). If a man is 180cm tall, what is his ideal body weight?

• A. 68kg
• B. 71kg
• C. 74kg
• D. 77kg

Correct answer: B

Rationale: Rationale: 1. Substitute the given height into the formula for calculating ideal body weight (IBW) for men: IBW (kg) = 50 + 2.3 * (180 - 150) IBW (kg) = 50 + 2.3 * 30 IBW (kg) = 50 + 69 IBW (kg) = 119 2. Therefore, the ideal body weight for a man who is 180cm tall is 119kg. 3. Among the given options, the closest value to 119kg is 71kg (option B). 4. Hence, the correct answer is B) 71kg.

2. How many milliliters are in 6 liters?

• A. 60 milliliters
• B. 6000 milliliters
• C. 600 milliliters
• D. 0.6 milliliters

Correct answer: B

Rationale: The correct answer is B: 6000 milliliters. There are 1,000 milliliters in a liter. To convert liters to milliliters, you multiply the number of liters by 1,000. Therefore, 6 liters = 6 × 1,000 = 6,000 milliliters. Choices A, C, and D are incorrect because they do not correctly convert liters to milliliters.

3. Which gland is responsible for regulating metabolism and calcium levels?

• A. Pituitary gland
• B. Adrenal gland
• C. Thyroid gland
• D. Pineal gland

Correct answer: C

Rationale: The correct answer is the thyroid gland (Choice C). The thyroid gland plays a crucial role in regulating metabolism by producing hormones like thyroxine, which control the body's metabolic rate. It also helps in controlling calcium levels in the blood through the release of calcitonin. The pituitary gland (Choice A) is known as the 'master gland' as it controls other glands but is not primarily responsible for regulating metabolism and calcium levels. The adrenal gland (Choice B) produces hormones like cortisol and adrenaline, which are involved in the stress response and metabolism, but they do not specifically regulate calcium levels. The pineal gland (Choice D) mainly produces melatonin, a hormone that helps in regulating sleep-wake cycles and has no direct role in metabolism or calcium level regulation.

4. Phenotype refers to the _ of an individual.

• A. Genetic makeup
• B. Actual physical appearance
• C. Recessive alleles
• D. None of the above

Correct answer: B

Rationale: Phenotype refers to the actual physical appearance and characteristics of an individual, which are determined by the interaction of both genetic makeup (genotype) and environmental factors. It includes visible traits such as height, eye color, and hair type. Choice A, genetic makeup, refers to the genotype, which is the genetic constitution of an organism. Choice C, recessive alleles, is a specific type of gene variant and does not encompass the entire concept of phenotype. Choice D, none of the above, is incorrect as phenotype does refer to the actual physical appearance of an individual.

5. Choose the meaning of the word suppress in the following sentence: 'A single dose will suppress even the nastiest cough.'

• A. Subdue
• B. Cure
• C. Restore
• D. Affect

Correct answer: A

Rationale: In the sentence, the word 'suppress' is synonymous with the word 'subdue.' To suppress a cough means to reduce or restrain it, which aligns with the meaning of subdue. The other options are incorrect: 'Cure' implies completely eliminating the cough, 'Restore' means to bring back to a former condition, and 'Affect' is too general and does not capture the specific meaning of 'suppress' in this context.
