2. To cauterize a wound is to ___________.

• A. soothe it
• B. cover it
• C. stitch it
• D. burn it

Correct answer: D

Rationale: To cauterize a wound is to use heat or a chemical to burn the wound in order to stop bleeding and prevent infection. This process helps seal off blood vessels and close the wound by burning the affected tissue. Choice A, 'soothe it,' is incorrect because cauterization involves burning the wound, which is a controlled way of treating it, not soothing it. Choice B, 'cover it,' is incorrect as cauterization involves a more aggressive approach than just covering the wound. Choice C, 'stitch it,' is incorrect as it refers to using sutures to close a wound, which is different from cauterization that involves burning the wound to seal it.

3. The speed of sound in dry air at 20°C is 343 m/s. If the wavelength of a sound wave is 5 m, what is its frequency?

• A. 171.5 Hz
• B. 79 Hz
• C. 68.6 Hz
• D. 63.6 Hz

Correct answer: C

Rationale: The speed of sound (v) can be calculated using the formula: v = f × λ, where f is the frequency and λ is the wavelength. Given that the speed of sound is 343 m/s and the wavelength is 5 m, we can rearrange the formula to solve for frequency: f = v / λ = 343 / 5 = 68.6 Hz. Therefore, the correct frequency is 68.6 Hz. Choices A, B, and D are incorrect as they do not result from the correct calculation based on the given values.

4. Which of the following endocrine system glands releases the thyrotrophic-releasing hormone, growth hormone-releasing hormone, and gonadotropin-releasing hormone?

• A. Thymus
• B. Pituitary gland
• C. Pineal gland
• D. Hypothalamus

Correct answer: D

Rationale: The correct answer is D, the Hypothalamus. The hypothalamus is responsible for releasing key hormones like thyrotrophic-releasing hormone, growth hormone-releasing hormone, and gonadotropin-releasing hormone. These hormones play essential roles in regulating various body functions by influencing the activities of other endocrine glands. Choices A, B, and C are incorrect because the thymus is involved in immune function, the pituitary gland releases different hormones, and the pineal gland primarily produces melatonin, not the hormones mentioned in the question.

5. Which part of the sentence contains a typographical error?

• A. To a
• B. Very strong
• C. Being
• D. Went from

Correct answer: D

Rationale: The correct answer is D. The phrase 'Went form' contains a typographical error. It should be 'went from' to indicate the change in condition correctly. Choice A 'To a,' choice B 'Very strong,' and choice C 'Being' are grammatically correct and do not contain any typographical errors in the given sentence.
