Biology

1. What is the function of the pituitary gland?

Correct answer: A

Rationale: The pituitary gland is often referred to as the "master gland" because it controls the activity of many other endocrine glands in the body. It is located at the base of the brain and produces a variety of hormones that regulate various bodily functions, including growth, metabolism, reproduction, and blood pressure.

2. What is the name for the smallest amount of an element that can exist independently and retain its chemical properties?

Correct answer: A

Rationale: An atom is the fundamental building block of an element, consisting of a nucleus and electrons.

3. What is the process of converting lactic acid back into pyruvate called?

Correct answer: C

Rationale: Rationale: A) Glycolysis is the process of breaking down glucose into pyruvate. B) Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources. C) The Cori cycle is the process by which lactic acid produced by anaerobic metabolism in muscles is transported to the liver and converted back into glucose or pyruvate. D) Oxidative phosphorylation is the process by which ATP is synthesized using energy derived from the transfer of electrons in the electron transport chain.

4. The formula for calculating heart rate is HR = (220 - age) * 0.65. If a patient's heart rate is 136.5, what is their age?

Correct answer: B

Rationale: Rearrange the formula to solve for age: age = 220 - (HR / 0.65). Substitute the heart rate (136.5) to get 40 years old.

5. A scientist observes a new species of plant with unusual leaves. They hypothesize that the leaves help capture more sunlight. Which observation would LEAST support this hypothesis?

Correct answer: A

Rationale: If the plant thrives in shade, it suggests the leaves may have adapted for other purposes than maximizing sunlight capture.

6. 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.
