1. Which gland is responsible for producing adrenaline?

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

Correct answer: B

Rationale: The correct answer is the Adrenal gland. The Adrenal glands, situated on top of the kidneys, are responsible for producing adrenaline. Adrenaline is a hormone that prepares the body for the fight-or-flight response during stress. Choice A, the Thyroid gland, is responsible for producing hormones that regulate metabolism, not adrenaline. Choice C, the Pituitary gland, regulates many of the body's functions by producing various hormones but is not responsible for adrenaline production. Choice D, the Pineal gland, produces melatonin, a hormone that regulates sleep-wake cycles, and is not responsible for adrenaline production.

2. A lab test result shows a blood glucose level of 5.5 millimoles per liter (mmol/L). What is the equivalent level in milligrams per deciliter (mg/dL)?

• A. 55 mg/dL
• B. 5.5 mg/dL
• C. 0.55 mg/dL
• D. 550 mg/dL

Correct answer: A

Rationale: To convert the blood glucose level from millimoles per liter (mmol/L) to milligrams per deciliter (mg/dL), we need to perform a double conversion. 1 millimole is equivalent to 180.15 milligrams, and 1 liter is equal to 10 deciliters. First, multiply the glucose level (5.5 mmol/L) by the conversion factor for millimoles to milligrams (180.15 mg/mmol), then divide by the conversion factor for liters to deciliters (10 dL/L): 5.5 mmol/L * 180.15 mg/mmol / 10 dL/L ≈ 55 mg/dL. Therefore, the equivalent blood glucose level in mg/dL is 55. Choice A is correct. Choice B is incorrect as it does not account for the conversion factors properly. Choices C and D are significantly off as they do not follow the correct conversion calculations.

3. What is the correct electron configuration for lithium?

• A. 1s²2s¹
• B. 1s²2s²
• C. 1s²2s¹2p¹
• D. 1s¹2s¹2p²

Correct answer: A

Rationale: The electron configuration for lithium is 1s²2s¹. Lithium has 3 electrons, and the configuration indicates that the first two electrons fill the 1s orbital, while the third electron fills the 2s orbital. Therefore, the correct electron configuration for lithium is 1s²2s¹. Choice B (1s²2s²) is incorrect as it represents the electron configuration for beryllium, not lithium. Choice C (1s²2s¹2p¹) includes the 2p orbital, which is not involved in lithium's electron configuration. Choice D (1s¹2s¹2p²) is incorrect as it does not accurately represent lithium's electron configuration.

4. To be admitted to the university, he ________ to make an application by May 15.

• A. Has
• B. Have
• C. Might
• D. Should

Correct answer: A

Rationale: The correct answer is 'A: Has.' In this sentence, 'he' is singular, so the verb should also be singular. 'Has' is the correct form of the verb for the third-person singular subject 'he.' The verb 'have' is plural and does not agree with the singular subject. 'Might' and 'should' are modal verbs that do not fit the context of the sentence requiring a simple verb form.

5. If a patient's condition is deteriorating, what is happening?

• A. They are improving
• B. They are getting worse
• C. They are stable
• D. They are recovering

Correct answer: B

Rationale: When a patient's condition is deteriorating, it means they are getting worse. This indicates a decline or worsening in their health status, requiring immediate attention or intervention. Choice A is incorrect because 'improving' means the opposite of deteriorating. Choice C is incorrect as 'stable' means there is no significant change. Choice D is incorrect as 'recovering' means getting better, which is the opposite of deteriorating.
