1. Which of the following phases of mitosis is characterized by the separation of sister chromatids and their movement to opposite poles?
- A. Metaphase
- B. Anaphase
- C. Anaphase
- D. Cytokinesis
Correct answer: B
Rationale: Rationale: During anaphase of mitosis, the sister chromatids, which are duplicated copies of a chromosome, separate and move towards opposite poles of the cell. This movement is facilitated by the shortening of microtubules attached to the chromatids. As a result, each pole of the cell receives a complete set of chromosomes, ensuring that the daughter cells produced after cell division will have the correct number of chromosomes. Metaphase is characterized by the alignment of chromosomes at the cell's equator, not their separation. Telophase is the phase following anaphase, where the separated chromatids reach the opposite poles and nuclear envelopes start to form around them. Cytokinesis is the final stage of cell division, where the cytoplasm is divided to form two separate daughter cells.
2. Ms. Valencia develops the standards to be followed. Among the following standards, which is
- A. The patients verbalized satisfaction of the nursing care received
- B. Rotation of duty will be done every four weeks for all patient care personnel.
- C. All patients shall have their weights taken recorded
- D. Patients shall answer the evaluation form before discharge
Correct answer: C
Rationale: The correct answer is C because it is a clear and specific standard that can be easily measured and monitored. Weight recording is a fundamental aspect of patient care and is essential for tracking changes in health status. Verbalized satisfaction (option A) is subjective and may not be consistently measurable. Rotation of duty (option B) is important but may not be a standard developed by a nurse manager. Answering an evaluation form before discharge (option D) is important but may not be a standard created by Ms. Valencia for all patients.
3. Which of these organs is NOT involved in the production of digestive enzymes?
- A. Mouth
- B. Stomach
- C. Pancreas
- D. Small intestine
Correct answer: A
Rationale: Rationale: A) Mouth: The mouth is involved in the mechanical breakdown of food through chewing and the initiation of carbohydrate digestion by the enzyme amylase in saliva, but it does not produce digestive enzymes. B) Stomach: The stomach produces gastric juices containing enzymes like pepsin that help break down proteins. C) Pancreas: The pancreas produces various digestive enzymes such as amylase, lipase, and proteases that aid in the digestion of carbohydrates, fats, and proteins. D) Small intestine: The small intestine produces enzymes such as peptidases, sucrase, lactase, and maltase that further break down proteins, carbohydrates, and fats for absorption. Therefore, the mouth is the organ that is NOT involved in the production of digestive enzymes.
4. When proofreading your writing, focus on:
- A. Changing the wording to sound more original.
- B. Ignoring minor grammatical errors like typos.
- C. Checking for clarity, consistency, and overall flow.
- D. Replacing common words with thesaurus alternatives.
Correct answer: C
Rationale: Proofreading involves correcting errors, refining sentence structure, and ensuring the writing achieves its purpose, clarity, and consistency.
5. Which neurotransmitter is responsible for stimulating muscle contraction?
- A. Dopamine
- B. Acetylcholine
- C. Serotonin
- D. Norepinephrine
Correct answer: B
Rationale: Rationale: Acetylcholine is the neurotransmitter responsible for stimulating muscle contraction at the neuromuscular junction. When an action potential reaches the end of a motor neuron, acetylcholine is released into the synaptic cleft and binds to receptors on the muscle cell membrane, leading to muscle contraction. Dopamine, serotonin, and norepinephrine are neurotransmitters that have different functions in the nervous system and are not directly involved in stimulating muscle contraction.
6. Based on the information provided, which statement is LEAST likely to be supported by the author?
- A. Energy storage technologies play a critical role in the future of renewable energy utilization.
- B. Smart grids can improve the reliability and efficiency of the electricity grid.
- C. Continued reliance on fossil fuels hinders long-term climate change mitigation goals.
- D. Technological advancements offer solutions to overcome challenges associated with renewable energy.
Correct answer: B
Rationale: While the passage mentions smart grids, its primary focus is on managing the intermittency of renewable energy, making B the least likely statement the author would strongly support.
