1. Select the context clue from the following sentence that helps you define the multiple meaning word formula: 'The mother gave her baby his formula after he woke up from his nap in the car.'

• A. mother
• B. baby
• C. nap
• D. car

Correct answer: B

Rationale: The correct answer is 'B: baby.' In the sentence, 'baby' is the context clue that helps define the multiple meaning word 'formula.' Here, 'formula' refers to baby food, as babies typically consume formula. The word 'baby' directly relates to the context of feeding a baby with formula. Choice A, 'mother,' is not directly related to the meaning of 'formula' in this context. Choices C and D, 'nap' and 'car,' are also not directly connected to the meaning of 'formula' as they do not provide any relevant information about the word's meaning in this sentence.

2. What are the moon-shaped white structures at the base of fingernails called?

• A. Lunulae
• B. Cuticle
• C. Hyponychium
• D. Matrix

Correct answer: A

Rationale: The correct answer is A: Lunulae. The moon-shaped white structures at the base of fingernails are known as lunulae. They are most prominent on the thumb and are situated at the base of the nail matrix. The lunula is the visible part of the nail matrix, which is responsible for generating new nail cells. Choice B, Cuticle, is incorrect as it refers to the thin layer of skin at the base of the nail plate. Choice C, Hyponychium, is incorrect as it is the skin that lies beneath the free edge of the nail. Choice D, Matrix, is incorrect as it is the area where the nail is formed, located under the cuticle.

3. What is the process called in which a substance changes from a gas to a liquid?

• A. Condensation.
• B. Evaporation.
• C. Sublimation.
• D. Vaporization.

Correct answer: A

Rationale: Condensation is indeed the correct answer. It is the process by which a substance changes from a gas to a liquid. This occurs when the temperature of a gas decreases enough for its particles to lose energy and come together to form a liquid. On the other hand, evaporation is the process of a liquid changing to a gas. Sublimation is the direct transition of a substance from a solid to a gas without passing through the liquid phase. Vaporization, on the other hand, is the general term for the process of a liquid changing to a gas, which includes both evaporation and boiling.

4. Which of the following statements is correct based on anatomical terms?

• A. The shoulder joint is proximal to the neck.
• B. The elbow joint is superior to the shoulder.
• C. The thoracic vertebrae are superior to the cervical vertebrae.
• D. The thumb is on the lateral aspect of the hand.

Correct answer: D

Rationale: Option D is the correct answer based on anatomical terms. The thumb is indeed located on the lateral aspect of the hand, following anatomical positioning. The terms 'proximal,' 'superior,' and 'inferior' are used in relation to the center of the body or a specific point of reference, while 'lateral' and 'medial' describe positions further away or closer to the midline of the body. Therefore, the thumb being on the lateral side of the hand is an accurate anatomical description. Choices A, B, and C are incorrect because they do not align with anatomical terminology. In anatomical terms, 'proximal' refers to a position closer to the center of the body, 'superior' indicates a position above or higher than another part, and 'inferior' signifies a position below or lower than another part. The shoulder joint is distal to the neck, the elbow is inferior to the shoulder, and the cervical vertebrae are superior to the thoracic vertebrae.

5. Which of the following infectious diseases can be caused by a protozoan parasite?

• A. Measles
• B. Malaria
• C. Mumps
• D. Mononucleosis

Correct answer: B

Rationale: The correct answer is B: Malaria. Malaria is caused by Plasmodium, a protozoan parasite transmitted through the bite of infected mosquitoes. Measles and mumps are viral diseases caused by separate viruses. Mononucleosis, on the other hand, is caused by the Epstein-Barr virus, which is also a viral infection. Therefore, choices A, C, and D are incorrect as they are caused by viruses, not protozoa.
