Question 1 of 5
A nurse is preparing to transfuse 250 mL of packed red blood cells (RBCs) to a client over 4 hr. Available is a blood administration set that delivers 10 gtt/mL. The nurse should set the manual blood transfusion to deliver how many gtt/min? (Round to the nearest whole number.)
Correct Answer: A
Rationale: To calculate the rate of infusion in gtt/min, we first need to find the total number of drops needed for 250 mL over 4 hours. 250 mL x 10 gtt/mL = 2500 drops total 4 hours x 60 min = 240 minutes 2500 drops / 240 min ≈ 10.4 gtt/min Since we need to round to the nearest whole number, the correct answer is 10 gtt/min (Choice A). Choice B (15 gtt/min), Choice C (20 gtt/min), and Choice D (25 gtt/min) are incorrect as they do not accurately reflect the calculated rate of infusion based on the given information.
Question 2 of 5
A nurse is assessing a client who has an abdominal aortic aneurysm. Which of the following manifestations should the nurse expect?
Correct Answer: A
Rationale: The correct answer is A: Lower back discomfort. Abdominal aortic aneurysm can present with lower back discomfort due to the pressure on surrounding structures. Chest pain (B) is not typically associated with abdominal aortic aneurysm. Dyspnea (C) and nausea (D) are also not common manifestations of this condition. Lower back discomfort is a key characteristic symptom that nurses should expect when assessing a client with an abdominal aortic aneurysm.
Question 3 of 5
What is a serious side effect of antimalarial DMARDs?
Correct Answer: A
Rationale: The correct answer is A: Retinal damage. Antimalarial DMARDs like hydroxychloroquine can cause retinal damage, leading to vision loss. This is a serious side effect because it can be irreversible and impact quality of life. Bone marrow suppression (B), pulmonary fibrosis (C), and hepatotoxicity (D) are potential side effects of other medications but are not commonly associated with antimalarial DMARDs. It is important to monitor patients on antimalarials for early signs of retinal damage to prevent permanent vision loss.
Question 4 of 5
Which medication is used for acute management of gout?
Correct Answer: A
Rationale: The correct answer is A: Colchicine. Colchicine is used for acute gout attacks as it reduces inflammation and pain by inhibiting the inflammatory response to urate crystals. Allopurinol, Febuxostat, and Probenecid are used for long-term management by lowering uric acid levels, not for acute attacks. Colchicine is the preferred choice for acute gout due to its anti-inflammatory effects.
Question 5 of 5
Which medication is used to treat systemic lupus erythematosus (SLE)?
Correct Answer: A
Rationale: The correct answer is A: Belimumab. Belimumab is a monoclonal antibody that specifically targets B-cell activating factor (BAFF) and is approved for the treatment of SLE. BAFF plays a role in B-cell survival and maturation, which are key factors in the pathogenesis of SLE. Methotrexate (B), Hydroxychloroquine (C), and Leflunomide (D) are also used in the treatment of SLE, but they do not specifically target the underlying mechanisms of the disease like Belimumab does. Methotrexate is more commonly used for arthritis in SLE, Hydroxychloroquine is used for mild SLE cases, and Leflunomide is used for rheumatoid arthritis.
