Question 1 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 2 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.
Question 3 of 5
While obtaining a health history, the nurse learns that the client is allergic to bee stings. When obtaining the client’s medication history, the nurse should determine if the client keeps which medication on hand?
Correct Answer: A
Rationale: Rationale: A: Diphenhydramine hydrochloride (Benadryl) is an antihistamine commonly used to treat allergic reactions, including those from bee stings. It can help alleviate symptoms like itching and swelling. Keeping Benadryl on hand is crucial for managing an allergic reaction promptly. Other Choices: B: Guaifenesin (Robitussin) is an expectorant used to treat coughs, not allergic reactions. C: Pseudoephedrine hydrochloride (Sudafed) is a decongestant used for nasal congestion, not allergic reactions. D: Loperamide (Imodium) is an antidiarrheal used to treat diarrhea, not allergic reactions.
Question 4 of 5
A client with acquired immunodeficiency syndrome (AIDS) is receiving zidovudine (azidothymidine, AZT [Retrovir]). To check for adverse drug effects, the nurse should monitor the results of laboratory test?
Correct Answer: D
Rationale: The correct answer is D: Platelet count. Zidovudine (AZT) is known to cause bone marrow suppression, leading to decreased platelet production. Monitoring platelet count is crucial to detect early signs of thrombocytopenia, a common adverse effect of AZT. Rationale: A) RBC count: AZT can cause anemia, not specifically affecting the RBC count. B) Serum calcium: AZT does not typically affect calcium levels. C) Fasting blood glucose: AZT can cause hyperglycemia, but fasting blood glucose monitoring is not as critical as monitoring platelet count for AZT therapy.
Question 5 of 5
A client agreed to become an organ donor is pronounced dead. What is the most important factor in selecting a transplant recipient?
Correct Answer: B
Rationale: The correct answer is B: Compatible blood and tissue types. This is crucial to minimize the risk of rejection and ensure a successful transplant. Matching blood and tissue types help prevent the recipient's immune system from attacking the new organ. Blood relationship (A) is not as important as compatibility. Sex and size (C) are important considerations for certain transplants but not the most crucial factor. Need (D) is relevant but does not outweigh the importance of compatibility to ensure a successful transplant.
