1. The speaker's enthusiasm was contagious. Which word is the noun form of the adjective "enthusiastic"?

• A. enthusiastic
• B. enthusiastically
• C. enthusiasm
• D. enthuse

Correct answer: C

Rationale: Nouns can be formed from adjectives using various suffixes.

2. Which of these pairs represents an example of convergent evolution?

• A. Humans and chimpanzees
• B. Bats and birds
• C. Dolphins and sharks
• D. Snakes and earthworms

Correct answer: B

Rationale: Rationale: Convergent evolution refers to the process by which different species independently evolve similar traits or characteristics due to similar environmental pressures. In the case of bats and birds, both have evolved wings for flight despite not sharing a recent common ancestor with wings. Bats are mammals, while birds are avians, yet they both have wings adapted for flight, which is a classic example of convergent evolution. A) Humans and chimpanzees share a common ancestor and have not independently evolved similar traits. C) Dolphins and sharks are not closely related, and their similarities are due to adaptations to their aquatic environment rather than convergent evolution. D) Snakes and earthworms belong to different classes (reptiles and annelids, respectively) and do not share recent common ancestors, making their similarities not a result of convergent evolution.

3. A reaction between an acid and a base is known as:

• A. Precipitation
• B. Neutralization
• C. Oxidation-reduction
• D. Photolysis

Correct answer: B

Rationale: When an acid and a base react, they neutralize each other's properties

4. Which of the following is NOT a recognized mode of natural selection?

• A. Directional selection (favoring one extreme trait value on a spectrum)
• B. Disruptive selection (favoring both extreme trait values on a spectrum)
• C. Stabilizing selection (favoring the average trait value on a spectrum)
• D. Sexual selection (selection based on mate choice that influences reproductive success)

Correct answer: D

Rationale: Rationale: A) Directional selection is a recognized mode of natural selection where one extreme trait value on a spectrum is favored over others. This can lead to a shift in the average trait value over time. B) Disruptive selection is a recognized mode of natural selection where both extreme trait values on a spectrum are favored over the average trait value. This can lead to the population splitting into two distinct groups. C) Stabilizing selection is a recognized mode of natural selection where the average trait value on a spectrum is favored over extreme values. This can lead to a reduction in genetic diversity within a population. D) Sexual selection is not a mode of natural selection in the traditional sense, as it involves mate choice and competition for mates rather than direct selection pressure on traits that affect survival and reproduction in the environment. Sexual selection can lead to the evolution of traits that enhance an individual's ability to attract

5. Which of the following is NOT a function of the muscular system?

• A. Movement
• B. Maintaining posture
• C. Generating heat
• D. Regulating blood sugar levels

Correct answer: D

Rationale: The correct answer is D: "Regulating blood sugar levels." The muscular system primarily functions in movement, maintaining posture, and generating heat. Muscles contract and relax to allow movement and help us stay upright. They also produce heat through muscle contractions to maintain body temperature. Regulating blood sugar levels is primarily controlled by the endocrine system, specifically the pancreas and hormones like insulin and glucagon. Therefore, this function is not directly related to the muscular system.

6. He raised the issue on giving priority to patient needs. Which of the following offers the best

• A. Assessing nursing needs and problems
• B. Giving instructions on how nursing care needs are to be met
• C. Controlling and evaluating the delivery of nursing care
• D. Assigning safe nurse: patient ratio

Correct answer: A

Rationale: In the context of the sentence 'He raised the issue on giving priority to patient needs,' the best option is 'Assessing nursing needs and problems' (Option A). This option directly aligns with the idea of prioritizing patient needs by first understanding and assessing the specific nursing needs and problems. By assessing these needs, healthcare providers can tailor their care to address the most pressing concerns of the patients, thus effectively giving priority to patient needs. The other options, such as giving instructions on how nursing care needs are to be met (Option B), controlling and evaluating the delivery of nursing care (Option C), and assigning safe nurse: patient ratio (Option D), do not directly address the importance of assessing patient needs as a crucial step in prioritizing patient care. Therefore, Option A is the most suitable choice in this scenario.
