HESI A2 Anatomy and Physiology Practice Test
1. Which of the following is not an example of a nonspecific immune response?
- A. Inflammation
- B. Vasodilation
- C. Release of histamine
- D. Production of antibodies
Correct answer: D
Rationale: The correct answer is D, 'Production of antibodies.' Antibodies are generated as part of the specific immune response, which targets specific antigens. Nonspecific immune responses, such as inflammation, vasodilation, and histamine release, are general defense mechanisms aimed at combating various pathogens. Inflammation is a localized response to infection or injury, vasodilation increases blood flow to the affected area, and histamine release triggers inflammatory responses. It's vital to differentiate between nonspecific responses that provide immediate, general protection and specific responses designed to tackle particular threats.
2. Select the meaning of the word 'PRN' in the sentence: 'The nurse gave the patient a PRN medication.'
- A. Pinpoint
- B. Relocate
- C. Eradicate
- D. Reduce
Correct answer: D
Rationale: 'PRN' is a medical abbreviation that stands for 'pro re nata,' meaning 'as needed.' In this context, the medication is given to reduce symptoms as they arise. Choice A, 'Pinpoint,' does not align with the meaning of 'PRN.' Choices B and C, 'Relocate' and 'Eradicate,' are unrelated to the concept of 'as needed' medications.
3. What is the correct pronoun to complete the sentence?
- A. Her
- B. Hers
- C. Best
- D. More greatest
Correct answer: A
Rationale: The word 'her' is the correct choice because it serves as the object of the preposition 'at.' In this sentence, 'looked at' requires an object pronoun, making 'her' the appropriate choice. Option B, 'Hers,' indicates possession, which is not needed in this context. Options C and D are not pronouns and do not fit grammatically in the sentence.
4. What is stated in the passage about the Olympic Games?
- A. The Olympic Games are held every four years.
- B. The Olympic Games are often postponed.
- C. The Olympic Games are held only in leap years.
- D. The Olympic Games only involve certain countries.
Correct answer: A
Rationale: The correct answer is A: 'The Olympic Games are held every four years,' as stated in the passage. The extract explicitly mentions that the Summer Olympic Games are held every four years. Choice B is incorrect as there is no mention of the Olympic Games being often postponed in the passage. Choice C is incorrect because although the Olympic Games occur during leap years, they are not exclusively held only in leap years. Choice D is incorrect as there is no indication in the passage that the Olympic Games only involve certain countries.
5. Select the phrase that will make the following sentence grammatically correct. Before I had finished supper, James ___________.
- A. is texting me on my cell phone
- B. had texted me on my cell phone
- C. texts me on my cell phone
- D. texting me on my cell phone
Correct answer: B
Rationale: The sentence starts with 'Before I had finished supper,' indicating that the action of James texting you on your cell phone had occurred before the completion of another past action (finishing supper). The past perfect tense 'had texted' is used to express an action that happened before another action in the past, making the sentence grammatically correct. Choice A is incorrect because it uses the present continuous tense, which is not suitable for indicating an action that occurred before finishing supper. Choice C is incorrect as it uses the simple present tense, which does not convey the sequence of events correctly. Choice D is incorrect as it presents the present continuous tense, which is not appropriate for the context of the sentence.
