Chemistry

1. A common indicator used to distinguish between acidic and basic solutions is:

Correct answer: B

Rationale: Phenolphthalein turns pink in basic solutions and remains colorless in acidic solutions

2. The process by which one element changes into another through radioactive decay is known as:

Correct answer: A

Rationale: Transmutation - Radioactive decay alters the atomic structure, changing the element's identity (transmutation).

3. A medication order is for 250 micrograms of a drug to be administered subcutaneously. The available syringe measures in milliliters. How many milliliters should the nurse draw up?

Correct answer: B

Rationale: First convert micrograms to milliliters, knowing 1000 micrograms equal 1 milliliter. Divide the desired dosage (250 micrograms) by the conversion factor (1000 micrograms/milliliter) to find the volume needed: 250 micrograms / 1000 micrograms/milliliter = 0.00025 milliliters. However, drawing such a small volume might be inaccurate, so round to the nearest practical measurement, which is 0.0025 milliliters.

4. Identify the bone with the greatest length in the human body.

Correct answer: A

Rationale: The femur, exceeding a meter in length, bears significant weight and enables locomotion.

5. Chyle, a milky white fluid, is transported by lymphatic vessels from the:

Correct answer: B

Rationale: The correct answer is B: Intestines. Chyle is a milky white fluid that is formed in the small intestine during digestion, mainly from the absorption of dietary fats. It is rich in fats and lymphocytes. Lymphatic vessels in the intestines, called lacteals, absorb the chyle and transport it through the lymphatic system. Chyle eventually enters the bloodstream via the thoracic duct. The lungs are responsible for gas exchange, not the transport of chyle. The kidneys are involved in filtering blood and producing urine. The skin is the body's largest organ responsible for protection, temperature regulation, and sensation, but it is not involved in transporting chyle.

6. How does an increase in surface area affect the force of friction between two surfaces?

Correct answer: b

Rationale: Increasing surface area reduces the force per unit area, decreasing friction.
