A nurse is administering a unit of packed red blood cells (RBCs) to a client who is postoperative. The client reports itching and has hives 30 min after the infusion begins. Which of the following actions should the nurse take first?

Correct Answer: A

Rationale: The correct action is A: Stop the infusion of blood. This is the first step because the client is experiencing signs of a transfusion reaction, likely an allergic reaction. Stopping the infusion is crucial to prevent further adverse effects. Continuing the infusion could lead to more severe reactions. Giving antihistamines (choice B) would be the next step after stopping the infusion to manage the allergic symptoms. Increasing the infusion rate (choice C) could exacerbate the client's reaction. Monitoring temperature (choice D) is important but not the priority in this situation.

Correct Answer: A

Rationale: The correct answer is A, Belimumab. Belimumab is a monoclonal antibody that targets B-lymphocyte stimulator protein, specifically approved for systemic lupus erythematosus (SLE). It helps reduce autoantibody production and inflammation in SLE patients. Methotrexate (B), Hydroxychloroquine (C), and Leflunomide (D) are not monoclonal antibodies. Methotrexate is a DMARD, Hydroxychloroquine is an antimalarial, and Leflunomide is a DMARD used for rheumatoid arthritis, not specifically for SLE.

Correct Answer: A

Rationale: The correct answer is A: Colchicine. Colchicine is used to treat acute gout attacks by reducing inflammation and pain caused by uric acid crystals in the joints. It works by inhibiting the inflammatory response to these crystals. Allopurinol, Febuxostat, and Probenecid are used for long-term management of gout by lowering uric acid levels, not for acute attacks. Colchicine is specifically indicated for treating acute gout attacks due to its anti-inflammatory properties.

Correct Answer: C

Rationale: Rationale: Choice C is the correct answer because it states an incorrect fact about Lyme disease. Lyme disease, if left untreated, is not usually fatal. It can lead to serious complications but is rarely fatal. This indicates a need for review. Choices A, B, and D are incorrect as they provide accurate information about Lyme disease prevention, symptoms, and treatment duration, respectively.

Correct Answer: A

Rationale: Step-by-step rationale for why choice A (Anisocytosis) is correct: 1. Anisocytosis refers to a condition where red blood cells vary significantly in size. 2. In this scenario, observing a large variation in red cell size on a blood film fits the definition of anisocytosis. 3. Anisocytosis is commonly associated with conditions like iron deficiency anemia or certain genetic disorders. 4. Therefore, in the context of the question, anisocytosis is the most appropriate term to describe the finding. Summary: - Choice A (Anisocytosis) is correct as it accurately describes the observed variation in red cell size. - Choices B, C, and D (Poikilocytosis, Haemachromatosis, Polychromasia) are incorrect as they do not specifically address the variation in cell size as seen in anisocytosis.
