1. The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both. Which of the following represents the LCM of 14 and 21?

• A. 42
• B. 63
• C. 84
• D. 168

Correct answer: C

Rationale: We can list out the multiples of each number until we find a common multiple. 14, 28, 42, 56, 84, ... 21, 42, 63, 84, ... The least common multiple is 84.

2. What is the milky-white fluid transported by the lymphatic vessels called?

• A. Plasma
• B. Blood
• C. Chyle
• D. Mucus

Correct answer: C

Rationale: The milky-white fluid transported by the lymphatic vessels is called 'Chyle.' Chyle is formed in the small intestine during the absorption of fats. It primarily consists of lymph and emulsified fats. Plasma refers to the liquid component of blood, while blood carries red blood cells, white blood cells, platelets, and plasma. Mucus is a slimy substance produced by mucous membranes. Therefore, option C, 'Chyle,' is the correct answer in this context.

3. What is the endoplasmic reticulum?

• A. A network of tubules that transport proteins and lipids throughout the cell
• B. A sac-like structure that stores water and nutrients
• C. The site of protein synthesis
• D. The site of cellular respiration

Correct answer: A

Rationale: Rationale: A) The endoplasmic reticulum (ER) is a network of tubules that are involved in the transport of proteins and lipids throughout the cell. It plays a crucial role in protein synthesis, folding, and transport within the cell. The ER can be further divided into rough ER, which has ribosomes attached to its surface and is involved in protein synthesis, and smooth ER, which is involved in lipid metabolism and detoxification. Therefore, option A is the most accurate description of the endoplasmic reticulum compared to the other options provided. B) A sac-like structure that stores water and nutrients does not accurately describe the endoplasmic reticulum. While some organelles like vacuoles or vesicles may store water and nutrients, the ER's primary function is not storage. C) The site of protein synthesis is partially

4. Choose the most appropriate word to complete the sentence "He was _____ about his upcoming presentation."

• A. apprehensive
• B. bored
• C. excited
• D. relieved

Correct answer: A

Rationale: "Apprehensive" implies a mild worry or nervousness, which best fits the context.

5. What is the process of separating a mixture based on the different boiling points of its components called?

• A. Filtration
• B. Chromatography
• C. Distillation
• D. Centrifugation

Correct answer: C

Rationale: This technique separates components based on their boiling points, allowing for the collection of fractions with different boiling ranges.

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

• A. Written nursing care plan
• B. Holistic approach
• C. Prescribed standards
• D. Staff preferences

Correct answer: D

Rationale: When formulating objectives for a written nursing care plan, staff preferences should be least considered. Objectives should be based on patient needs, evidence-based practice, and professional standards rather than personal preferences of the staff. Prescribed standards ensure quality care and adherence to best practices. A holistic approach considers the whole patient, including physical, emotional, and spiritual aspects. Staff preferences may introduce bias and should not dictate patient care objectives.
