Metric Conversions for Nursing

1. What is 0.04 g in mg?

Correct answer: A

Rationale: To convert grams to milligrams, you multiply by 1000 since there are 1000 milligrams in a gram. Therefore, to convert 0.04 grams to milligrams, you would do 0.04 * 1000 = 40 mg. Choice A, '40 mg,' is the correct answer. Choices B, C, and D are incorrect because they do not correctly convert grams to milligrams. Choice B, '400 mg,' is incorrect because it mistakenly multiplies by 10 instead of 1000. Choice C, '4 mg,' is incorrect because it does not account for the correct conversion factor. Choice D, '0.4 mg,' is incorrect because it underestimates the conversion by a factor of 10.

2. Which of the following functions is NOT performed by the integumentary system, the skin?

Correct answer: D

Rationale: The integumentary system, which includes the skin, performs various functions like protecting internal tissues from injury, waterproofing the body, and helping regulate body temperature. The function of returning fluid to the blood vessels is primarily associated with the lymphatic system, not the integumentary system. The skin contributes to fluid balance by regulating sweating and preventing excessive water loss, but it does not directly return fluid to the blood vessels, making this the correct answer. Choices A, B, and C are functions directly related to the integumentary system and are essential for maintaining the body's overall health and well-being.

3. What is the most effective way to combine the following sentences? 1. The colonists refused to buy stamps. 2. They were determined to get the Stamp Act repealed.

Correct answer: B

Rationale: The conjunction 'and' is used to connect the two independent clauses in the most effective and grammatically correct way. This choice maintains the clarity of the sentence and the relationship between the two ideas. Choice A is incorrect as it lacks the necessary conjunction to properly connect the two independent clauses. Choice C is incorrect as it misses the subject 'they' before 'were determined.' Choice D is incorrect as it lacks the necessary coordinating conjunction 'and' before 'were determined,' resulting in a run-on sentence.

4. What is the outermost layer of the dermis, rich in collagen and elastin fibers that provide elasticity to the skin?

Correct answer: B

Rationale: The correct answer is the reticular layer. This layer is the outermost layer of the dermis that contains abundant collagen and elastin fibers, providing elasticity to the skin. The papillary layer is located beneath the epidermis and is responsible for supplying nutrients to the epidermis, not the outermost layer. The stratum basale is the deepest layer of the epidermis where new skin cells are produced, not part of the dermis. The stratum corneum is the outermost layer of the epidermis composed of dead skin cells, not a layer of the dermis.

5. Which of the following blood proteins can destroy pathogens?

Correct answer: A

Rationale: The correct answer is A: Complement system. The complement system is a vital component of the immune system responsible for destroying pathogens through various mechanisms like promoting inflammation, enhancing phagocytosis, and directly lysing pathogens. Fibrinogen is crucial for blood clotting, the major histocompatibility complex is involved in immune responses, and platelets aid in blood clotting and wound healing. However, none of these directly destroy pathogens as the complement system does.
