What is the function of an artificial airway?

Correct Answer: B

Rationale: The correct answer is B: To keep the airway open for the lungs to perform air exchange. An artificial airway is used to maintain a clear passage for air to enter the lungs when a person is unable to do so independently. This helps prevent respiratory distress and ensures proper oxygenation. Choices A, C, and D are incorrect because feeding a resident, checking vital signs, or preparing for a medical test are not primary functions of an artificial airway.

Correct Answer: C

Rationale: Step 1: A living will is a legal document that outlines an individual's preferences for medical treatment in case they become incapacitated. Step 2: Choice C aligns with the definition of a living will as it mentions stating medical care preferences. Step 3: Choices A, B, and D are incorrect as they do not relate to the purpose of a living will. Step 4: Choice A talks about estate distribution after death, not medical care decisions. Step 5: Choice B mentions inheritance wishes, which are typically covered in a will, not a living will. Step 6: Choice D discusses financial affairs management, which is addressed in a power of attorney, not a living will. Step 7: Therefore, Choice C is the correct answer as it accurately describes the purpose of a living will in managing medical care preferences.

Correct Answer: D

Rationale: The correct answer is D: Tachy in tachycardia. A prefix is a word part added to the beginning of a base word to change its meaning. In this case, "tachy" is a prefix meaning fast or rapid. In tachycardia, it modifies the base word "cardia," referring to the heart, to indicate a rapid heart rate. Choices A, B, and C all contain word parts, but they are not prefixes. "Scope," "logy," and "ostomy" are all suffixes or root words, not added at the beginning of a base word to change its meaning.

Correct Answer: A

Rationale: The correct answer is A: Social development. School-age children undergo significant social development as they interact with peers, develop friendships, and learn to navigate social situations. This is a crucial aspect of their overall growth and impacts their emotional well-being. Choices B, C, and D are incorrect as they do not specifically relate to school-age children's development. Pregnancy (choice B) is not relevant to children, learning to walk correctly (choice C) is more relevant to infants or toddlers, and controlling bowels and bladders (choice D) is typically mastered during the earlier stages of development.

Correct Answer: D

Rationale: The correct answer is D: Vaccine. A vaccine is administered to produce immunity to a specific disease by triggering the body's immune response to recognize and fight off the disease-causing agent, such as a virus or bacteria. Vaccines contain weakened or inactive forms of the pathogen to stimulate the immune system without causing the actual disease. A) Vesicle: A vesicle is a small fluid-filled sac and is not used to produce immunity to diseases. B) Vector: A vector is an organism that carries and transmits a pathogen, such as mosquitoes carrying malaria, but it is not administered to produce immunity. C) Vacuum: A vacuum is a space devoid of matter, and it is not related to immunity or disease prevention. In summary, the other choices are incorrect because they do not serve the specific purpose of producing immunity to a disease like a vaccine does.
