Anatomy

1. Which of the following is NOT a symptom of asthma, a chronic respiratory condition?

Correct answer: D

Rationale: The correct answer is D: "Fever." Fever is not a symptom commonly associated with asthma. Asthma symptoms typically include wheezing (A), difficulty breathing (B), and chest tightness (C). Wheezing is a high-pitched whistling sound that occurs during breathing, while difficulty breathing refers to the feeling of not getting enough air. Chest tightness is a common sensation of pressure or constriction in the chest. Fever is not a typical symptom of asthma but may occur in other respiratory conditions or infections. Therefore, fever is the correct answer as it does not align with the typical symptom profile of asthma.

2. The word "obscurity" can be replaced with which of the following without changing the meaning?

Correct answer: B

Rationale: Both "obscurity" and "seclusion" imply being hidden or unknown. Prominence, destruction, and transformation do not convey the same meaning.

3. Antibiotic resistance in bacteria is an example of:

Correct answer: C

Rationale: Rationale: - Convergent evolution (option A) refers to the process by which different species evolve similar traits independently in response to similar environmental pressures. Antibiotic resistance in bacteria does not involve different species evolving similar traits. - Divergent evolution (option B) refers to the process by which two or more related species become more dissimilar over time. Antibiotic resistance in bacteria does not involve related species becoming more dissimilar. - Microevolution (option C) refers to changes in allele frequencies within a population over a relatively short period of time. Antibiotic resistance in bacteria is a classic example of microevolution, where bacteria evolve resistance to antibiotics through the natural selection of pre-existing resistant strains. - Macroevolution (option D) refers to large-scale evolutionary changes that result in the formation of new species or higher taxonomic groups. Antibiotic resistance in bacteria does not involve

4. Which of the following hormones is produced by the adrenal medulla and prepares the body for a stressful situation?

Correct answer: C

Rationale: The correct answer is C: Epinephrine (adrenaline). Epinephrine is produced by the adrenal medulla and is responsible for preparing the body for a stressful situation, often referred to as the 'fight or flight' response. Testosterone is a hormone produced by the testes in males and in smaller amounts by the ovaries in females, responsible for male sexual characteristics. Cortisol is produced by the adrenal cortex and plays a role in regulating metabolism and immune response. Growth hormone is produced by the pituitary gland and is essential for growth, cell repair, and metabolism. Therefore, epinephrine is the hormone specifically produced by the adrenal medulla to prepare the body for stress.

5. A nurse needs to administer 0.8 milliliters of medication. The only available syringe measures in teaspoons. How many teaspoons should the nurse use?

Correct answer: B

Rationale: Rationale: 1 milliliter is equivalent to approximately 0.2 teaspoons. Therefore, to find out how many teaspoons are in 0.8 milliliters, we can set up a proportion: 0.8 milliliters * 0.2 teaspoons/1 milliliter = 0.16 teaspoons Since 0.16 teaspoons is not one of the answer choices, we need to convert it to a more practical measurement. The closest option is 0.4 teaspoons, which is the correct answer.

6. A solution is considered saturated when...

Correct answer: B

Rationale: The correct answer is B: 'The solvent starts to evaporate.' A solution is considered saturated when the solvent can no longer dissolve any more solute at a given temperature. When the solvent starts to evaporate, it means that the solution is becoming more concentrated and reaching its saturation point. This is a key indicator of a saturated solution. The other options do not accurately describe the concept of a saturated solution, making them incorrect choices.
