1. A patient weighs 180 pounds. What is their weight in kilograms (1kg = 2.2lbs)?

• A. 68kg
• B. 75kg
• C. 82kg
• D. 90kg

Correct answer: C

Rationale: To convert pounds to kilograms, you need to divide the weight in pounds by the conversion factor of 2.2 (1kg = 2.2lbs). 180 pounds / 2.2 = 81.82 kg Rounded to the nearest whole number, the weight of 180 pounds is approximately 82kg. Therefore, the correct answer is 82kg, which is option C. Option B (75kg) is not correct as it is significantly lower than the calculated value. Options A (68kg) and D (90kg) are also incorrect as they do not match the converted weight of 180 pounds.

2. A farmer wants to plant trees around the outside boundaries of his rectangular field with dimensions of 650 meters × 780 meters. Each tree requires 5 meters of free space all around it from the stem. How many trees can he plant?

• A. 572
• B. 568
• C. 286
• D. 282

Correct answer: C

Rationale: To determine the number of trees, reduce the field dimensions by 10 meters (5 meters of space on each side). The effective area is 640 meters × 770 meters. Each tree occupies 10 meters × 10 meters. Dividing the effective area by the space for each tree gives: (640 × 770) ÷ (10 × 10) = 286 trees. Choice A, B, and D are incorrect because they do not consider the reduction in field dimensions and the space required for each tree.

3. What is the primary function of the alveoli in the lungs?

• A. Removing carbon dioxide from the blood
• B. Exchanging oxygen and carbon dioxide
• C. Transporting oxygen to the bloodstream
• D. Filtering blood

Correct answer: B

Rationale: The primary function of the alveoli in the lungs is to exchange oxygen and carbon dioxide. The alveoli are tiny air sacs in the lungs responsible for this gas exchange during breathing. Oxygen diffuses from the inhaled air into the blood in the capillaries surrounding the alveoli, while carbon dioxide diffuses from the blood into the alveoli to be exhaled out of the body. Choice A is incorrect because the alveoli primarily facilitate the exchange of gases, not just the removal of carbon dioxide. Choice C is incorrect as the alveoli do not transport oxygen to the bloodstream but rather facilitate the exchange of gases. Choice D is incorrect as the alveoli are not involved in filtering blood but in gas exchange to ensure proper oxygenation and removal of carbon dioxide in the respiratory process.

4. Which term is descriptive of a small child just learning to walk?

• A. Obese
• B. Toddler
• C. Geriatric
• D. Hale

Correct answer: B

Rationale: The correct answer is 'B: Toddler.' A toddler is a young child typically between the ages of one and three who is just learning to walk. 'Obese' (choice A) refers to excess body fat, 'Geriatric' (choice C) pertains to elderly individuals, and 'Hale' (choice D) means strong and healthy, none of which are descriptive of a small child learning to walk.

5. What does intact mean?

• A. Damaged
• B. In place, unharmed
• C. Destroyed
• D. Incomplete

Correct answer: B

Rationale: The correct answer is B: 'In place, unharmed.' 'Intact' refers to something that is whole, undamaged, or unharmed. Choices A, C, and D are incorrect because they describe states opposite to what intact means. 'Damaged,' 'Destroyed,' and 'Incomplete' all signify a lack of wholeness or harm, which is contrary to the meaning of intact.
