A nurse is assessing a client who has right-sided heart failure. Which of the following findings should the nurse expect?

Correct Answer: A

Rationale: The correct answer is A: Dependent edema. In right-sided heart failure, the weakened right ventricle fails to effectively pump blood, leading to fluid retention and congestion in the systemic circulation. This results in dependent edema, typically seen in the lower extremities. Pulmonary crackles (B) are associated with left-sided heart failure due to fluid accumulation in the lungs. Shortness of breath (C) is a common symptom of both left-sided and right-sided heart failure. Chest pain (D) is not a typical finding in right-sided heart failure unless there is an underlying cause such as myocardial infarction.

Correct Answer: A

Rationale: The correct answer is A: Initiate weekly injections of vitamin B12. Pernicious anemia is caused by a lack of intrinsic factor, leading to poor absorption of vitamin B12. Injecting B12 bypasses the need for intrinsic factor. Increasing dietary iron (B) is not indicated for pernicious anemia. Administering oral B12 (C) is ineffective due to poor absorption. Providing folic acid supplements (D) is not the primary intervention for pernicious anemia.

Correct Answer: B

Rationale: The correct answer is B: Hydroxychloroquine. It is an antimalarial DMARD (Disease-Modifying Anti-Rheumatic Drug) commonly used to treat rheumatoid arthritis and lupus. Hydroxychloroquine works by reducing inflammation and suppressing the immune system. Methotrexate (A) is a DMARD but not used for malaria. Leflunomide (C) is also a DMARD for rheumatoid arthritis. Adalimumab (D) is a biologic DMARD used for autoimmune diseases like rheumatoid arthritis, but not for malaria. In summary, hydroxychloroquine is the correct choice as it is specifically indicated for treating malaria among the options provided.

Correct Answer: A

Rationale: The correct answer is A: Acute pulmonary edema. Belimumab is a monoclonal antibody used to treat systemic lupus erythematosus, and one of its serious adverse effects is acute pulmonary edema. This can occur due to an allergic reaction to the medication, resulting in fluid accumulation in the lungs. Bone marrow suppression (choice B) is not a common adverse effect of belimumab. Retinal damage (choice C) is not associated with belimumab use. Hepatotoxicity (choice D) is a known adverse effect of some medications but is not a prominent concern with belimumab. Therefore, the correct answer is A, as it aligns with the drug's known adverse effects.

Correct Answer: A

Rationale: Probenecid is the correct answer as it inhibits renal reabsorption of urates by blocking the URAT1 transporter. By decreasing uric acid reabsorption, it increases urate excretion, thus lowering serum uric acid levels. Allopurinol and Febuxostat are xanthine oxidase inhibitors used to reduce uric acid production, not reabsorption. Colchicine is used to treat acute gout attacks by reducing inflammation and does not affect urate reabsorption.
