1. Identify the adverb in the following sentence: The patient waited anxiously for the doctor's news.

• A. waited
• B. anxiously
• C. doctor's
• D. news

Correct answer: B

Rationale: Adverbs modify verbs, adjectives, or other adverbs. In this sentence, "anxiously" describes how the patient "waited".

2. The "fight-or-flight" response is triggered by the hormone released from the:

• A. Thyroid gland
• B. Adrenal glands
• C. Pituitary gland
• D. Pancreas

Correct answer: B

Rationale: The correct answer is B: Adrenal glands. The "fight-or-flight" response is a physiological reaction that occurs in response to a perceived threat or danger. When this response is triggered, the adrenal glands release adrenaline, also known as epinephrine, into the bloodstream. This hormone prepares the body for action by increasing heart rate, dilating airways, and redirecting blood flow to essential organs. The thyroid gland (option A) primarily regulates metabolism, the pituitary gland (option C) controls many other hormone glands, and the pancreas (option D) is responsible for regulating blood sugar levels through the production of insulin and glucagon, but they are not directly involved in the fight-or-flight response.

3. What is the process by which a fertilized egg implants itself in the lining of the uterus?

• A. Fertilization
• B. Implantation
• C. Gestation
• D. Parturition

Correct answer: B

Rationale: The correct answer is B: Implantation. Implantation is the process by which a fertilized egg, or zygote, attaches itself to the uterine wall to establish a pregnancy. Fertilization is the fusion of sperm and egg to form a zygote, which occurs in the fallopian tube. Gestation refers to the period of development of the fetus inside the uterus. Parturition is the process of giving birth. Therefore, implantation specifically refers to the attachment of the fertilized egg to the uterine lining, making it the most appropriate answer in this context.

4. Which of the following functional groups is present in carboxylic acids?

• A. Carbonyl
• B. Hydroxyl
• C. Carboxyl
• D. Aldehyde

Correct answer: C

Rationale: Carboxylic acids contain the carboxyl functional group (-COOH). The other choices are associated with different functional groups.

5. A decorative box has a rectangular base (20cm by 15cm) and a hemispherical top with the same diameter as the base. What is the total surface area of the box (excluding the base)?

• A. 825 sq cm
• B. 1075 sq cm
• C. 1325 sq cm
• D. 1575 sq cm

Correct answer: C

Rationale: Calculate the surface area of the lateral sides and the hemisphere, then add them up.

6. A nurse needs to dilute 2 milliliters of a concentrated medication with 8 milliliters of sterile water. What is the final concentration of the solution in percent?

• A. 16.67%
• B. 20%
• C. 25%
• D. 50%

Correct answer: B

Rationale: Calculate the total volume of the solution (2 ml + 8 ml = 10 ml). Then, divide the volume of the concentrated medication by the total volume and multiply by 100%: (2 ml / 10 ml) * 100% = 20%.
