1. Select the correct definition of the word 'prognosis' in the sentence: 'The doctor’s prognosis gave the patient reason to feel optimistic.'

• A. Instructions
• B. Estimate
• C. Behavior
• D. Outcome statement

Correct answer: D

Rationale: In the context provided, 'prognosis' refers to a doctor's prediction or statement about the likely outcome of a disease or condition. This makes 'Outcome statement' the correct choice. 'Instructions' (A) are not related to prognosis. 'Estimate' (B) is a rough calculation or approximation, not a prediction of an outcome. 'Behavior' (C) refers to actions, conduct, or manner of an individual, which is not the meaning of 'prognosis' in this sentence.

2. Which reflexive pronoun correctly completes the sentence? 'When a person finds ___ in a stressful situation, it helps to breathe deeply.'

• A. Themselves
• B. Itself
• C. Yourself
• D. Oneself

Correct answer: D

Rationale: 'Oneself' is the correct reflexive pronoun to use when referring to an unspecified person. In this sentence, 'oneself' is used to indicate any individual without specifying gender or number. Choices A, B, and C are incorrect as they refer to specific or known individuals, which does not fit the context of the sentence.

3. A hummingbird’s wings beat at 25 beats per second. What is the period of the wing beating in seconds?

• A. 0.04 s
• B. 0.25 s
• C. 0.4 s
• D. 4 s

Correct answer: A

Rationale: The period represents the time for one complete cycle of the wing beating. To calculate the period, you take the reciprocal of the frequency. In this case, with the wings beating at 25 beats per second, the period is 1/25, which equals 0.04 seconds. Therefore, choice A, 0.04 seconds, is correct. Choices B, C, and D are incorrect because they do not reflect the correct calculation of the period based on the given frequency of 25 beats per second.

4. A patient's weight is measured as 75 kilograms. What is their weight in pounds?

• A. 132 pounds
• B. 150 pounds
• C. 110 pounds
• D. 85 pounds

Correct answer: B

Rationale: Rationale: To convert kilograms to pounds, you can use the conversion factor 1 kilogram is approximately equal to 2.20462 pounds. Therefore, to convert 75 kilograms to pounds: 75 kilograms * 2.20462 pounds/kilogram ≈ 165.3475 pounds Rounded to the nearest whole number, the patient's weight of 75 kilograms is approximately 165 pounds. Among the given options, the closest weight in pounds to 165 is 150 pounds (option B).

5. What part of the eye is responsible for focusing light on the retina?

• A. Cornea
• B. Lens
• C. Retina
• D. Pupil

Correct answer: B

Rationale: The lens of the eye is responsible for focusing light on the retina. When light enters the eye, it first passes through the cornea, which helps in bending the light, and then the lens further refracts and focuses the light onto the retina at the back of the eye. The retina contains photoreceptor cells that convert light into neural signals, which are then sent to the brain for visual processing. The cornea is the transparent outermost layer of the eye that helps in focusing light, but the main responsibility lies with the lens. The retina is the layer at the back of the eye that receives the focused light and initiates the process of vision. The pupil is the opening in the center of the iris that controls the amount of light entering the eye and is not directly involved in focusing light on the retina.
