Question 1 of 5
Why may an ice collar be ordered for a client who is undergoing drainage of a peritonsillar abscess?
Correct Answer: B
Rationale: The correct answer is B: To prevent respiratory obstruction. An ice collar is used to reduce swelling and inflammation, which can help prevent the abscess from compressing the airway and causing respiratory obstruction. This is crucial in cases of peritonsillar abscess to ensure the client's airway remains patent. Choices A, C, and D do not directly address the primary concern of preventing respiratory obstruction in this context.
Question 2 of 5
Which of the following is the function of macrophages and neutrophils?
Correct Answer: A
Rationale: The correct answer is A: Phagocytosis. Macrophages and neutrophils are both types of phagocytes responsible for engulfing and digesting pathogens such as bacteria. This process helps in clearing infections and maintaining immune homeostasis. Summary: - Choice B (Complement fixation) is incorrect as it refers to a process where complement proteins bind to pathogens to enhance their removal by phagocytes. - Choice C (Antibody production) is incorrect as macrophages and neutrophils do not produce antibodies. They mainly rely on phagocytosis for pathogen clearance. - Choice D (Suppression of autoimmunity) is incorrect as these cells are involved in innate immunity and do not play a direct role in regulating autoimmunity.
Question 3 of 5
The nurse understands that an anaphylactic reaction is considered which of the following types of hypersensitivity reactions?
Correct Answer: A
Rationale: The correct answer is A: Type I hypersensitivity reaction. In Type I hypersensitivity, anaphylactic reactions involve immediate IgE-mediated responses to allergens, leading to histamine release and potentially life-threatening symptoms. This type of reaction is characterized by rapid onset and systemic involvement. Choices B, C, and D are incorrect because Type III reactions involve immune complex deposition leading to inflammation (B), Type II reactions involve cytotoxic antibodies targeting cells (C), and Type IV reactions involve delayed cell-mediated responses (D).
Question 4 of 5
A patient who is being tested for HIV asks what tests are used. The nurse would correct in stating that the tests used to confirm HIV infection are which of the following?
Correct Answer: B
Rationale: The correct answer is B: ELISA and Western Blot. The rationale is as follows: ELISA (enzyme-linked immunosorbent assay) and Western Blot are specific tests used to confirm HIV infection by detecting antibodies or antigens related to the virus. ELISA is the initial screening test, while Western Blot is the confirmatory test. These tests are highly sensitive and specific for HIV detection. Choice A is incorrect because CD4+ cell count and thymus function are not tests used to confirm HIV infection. They are used to monitor disease progression and immune function in HIV-positive individuals. Choice C is incorrect because B-cell and T-cell count are also not tests used to confirm HIV infection. They are indicators of immune system health but not specific for HIV diagnosis. Choice D is incorrect because while CD4+ and viral load tests are used in monitoring HIV progression, ELISA is the main confirmatory test for HIV diagnosis, and viral load is not typically used for initial
Question 5 of 5
A client with allergic rhinitis is prescribed loratadine (Claritin). On a follow-up visit, the client tells the nurse, “I take one 10-mg of Claritin with a glass of water two times daily”. The nurse concludes that the client requires additional teaching about this medication because:
Correct Answer: C
Rationale: Rationale: 1. Loratadine is typically dosed once daily, not twice daily, for allergic rhinitis. 2. Taking it twice daily may increase the risk of side effects without added benefit. 3. The client's dosing schedule reflects a misunderstanding of the medication regimen. 4. Option A is incorrect because loratadine is available in 10mg tablets. 5. Option B is incorrect as loratadine can be taken with or without food. 6. Option D is incorrect as Claritin is a common trade name for loratadine.
