Mathematics

1. Simplify the expression: -5 + (-8)

Correct answer: A

Rationale: Combine the negative signs by adding them together. -5 + (-8) = -13

2. Which of the following guidelines should be least considered in formulating objectives for

Correct answer: D

Rationale: When formulating objectives for a written nursing care plan, staff preferences should be the least considered guideline. Objectives in a care plan should be based on the patient's needs, evidence-based practices, and prescribed standards of care to ensure quality and effective treatment. Staff preferences may introduce biased decisions that do not align with the best interests of the patient. It is crucial to prioritize holistic care, which considers all aspects of the patient's well-being, and adhere to prescribed standards to provide comprehensive and individualized care. By disregarding staff preferences and focusing on what is best for the patient, healthcare professionals can deliver optimal care that promotes patient outcomes and satisfaction.

3. What is the myelin sheath and what does it do?

Correct answer: B

Rationale: The correct answer is B. The myelin sheath is a fatty substance that insulates some nerve fibers. It is essential for the proper functioning of the nervous system as it acts as an insulator, allowing for faster transmission of nerve impulses along the axon. Without the myelin sheath, nerve signals could be disrupted or weakened, leading to issues with movement, sensation, and other neurological functions. Options A, C, and D are incorrect as they do not accurately describe the myelin sheath or its function.

4. Your hypothesis predicts that exposing plants to classical music will enhance their growth. How could you design an experiment to test this hypothesis?

Correct answer: A

Rationale: To test the hypothesis that exposing plants to classical music enhances their growth, the most appropriate experimental design would be to play classical music to all plants in the greenhouse (experimental group) and compare their growth to a control group of plants that are not exposed to any music. This design allows for a direct comparison between the effects of classical music exposure on plant growth, eliminating confounding variables that may arise from individual plant preferences or different music genres.

5. Which condition is characterized by inflammation of the inner lining of the stomach?

Correct answer: D

Rationale: The correct answer is D, gastritis. Gastritis refers to the inflammation of the inner lining of the stomach, which can be caused by various factors such as excessive alcohol consumption, prolonged use of NSAIDs, or bacterial infections like H. pylori. Gastroesophageal reflux disease (GERD) is characterized by the backflow of stomach acid into the esophagus, not inflammation of the stomach lining. Diverticulitis is inflammation of small pouches that can develop in the colon, while ulcerative colitis is inflammation in the large intestine. Therefore, gastritis best fits the description of inflammation in the inner lining of the stomach.

6. Define work in physics.

Correct answer: c

Rationale: Work in physics is the transfer of energy when a force is applied and the object moves in the direction of the force.
