1. When you get a goosebump, which type of muscle tissue is responsible for causing the hair follicles to stand on end?

A. Skeletal muscle
B. Smooth muscle
C. Cardiac muscle
D. None of the above

Correct answer: B

Rationale: When you get a goosebump, the type of muscle tissue responsible for causing the hair follicles to stand on end is smooth muscle. Smooth muscle is found in the skin attached to hair follicles and is controlled by the autonomic nervous system. When stimulated by factors like cold or emotional responses, the smooth muscle contracts, causing the hair to stand up and creating goosebumps. Skeletal muscle (choice A) is responsible for voluntary movements, cardiac muscle (choice C) is found in the heart and is responsible for pumping blood, and none of the above (choice D) is incorrect as smooth muscle is the correct answer in this case.

2. Isotopes are variants of a single element that differ in:

A. Having the same number of protons but varying numbers of neutrons
B. Having the same number of neutrons but varying numbers of protons
C. Having the same mass but different atomic numbers
D. None of the above

Correct answer: A

Rationale: The correct answer is A: 'Having the same number of protons but varying numbers of neutrons.' Isotopes are atoms of the same element with the same number of protons (which determines the element) but different numbers of neutrons. This results in isotopes having slightly different atomic masses. Options B and C are incorrect because isotopes specifically refer to variations in the number of neutrons, not protons or atomic numbers. Option D is incorrect because isotopes do exist due to differences in neutron number.

3. Identify the indirect object in the following sentence: "He gave his mother a bouquet of flowers."

A. mother
B. bouquet
C. flowers
D. gave

Correct answer: A

Rationale: The indirect object tells who or what benefits from the action of the verb.

4. During which phase of the cell cycle does cytokinesis typically occur?

A. Interphase
B. Mitosis
C. Meiosis
D. G2 phase

Correct answer: B

Rationale: Rationale: Cytokinesis is the process of dividing the cytoplasm of a cell into two daughter cells after the nucleus has divided during mitosis. In the cell cycle, cytokinesis typically occurs at the end of the mitotic phase, following the separation of the duplicated chromosomes into two identical sets in the daughter nuclei. Interphase (option A) is the phase where the cell grows, carries out its normal functions, and prepares for cell division. Meiosis (option C) is a specialized type of cell division that occurs in sexually reproducing organisms to produce gametes. G2 phase (option D) is the phase of the cell cycle following DNA replication in S phase and preceding mitosis, where the cell prepares for cell division.

5. Katherine is a young Unit Manager of the Pediatric Ward. Most of her staff nurses are senior

A. Identify the source of the conflict and understand the points of friction
B. Disregard what she feels and continue to work independently
C. Seek help from the Director of Nursing
D. Quit her job and look for another employment.

Correct answer: C

Rationale: The correct answer is C: Seek help from the Director of Nursing. As a young Unit Manager managing a team of senior staff nurses, Katherine may face challenges in leading and gaining the respect of her team due to the age and experience gap. Seeking help from the Director of Nursing can provide her with guidance, mentorship, and support in navigating these challenges. It is important for Katherine to communicate openly about any conflicts or issues she may be facing in order to address them effectively and maintain a positive work environment. Quitting her job (option D) should be considered as a last resort after exhausting all other possible solutions.
