Correct Answer: B

Rationale: Corrected Rationale: Planning in nursing involves setting priorities based on the identified patient needs, establishing goals, and developing a plan of care. Evaluation involves assessing the effectiveness of the care provided, implementation is the phase where the care plan is carried out, and assessment is the initial step of collecting data to identify the patient's needs. Therefore, in the context of determining nursing care priorities, the correct step is Planning (choice B).

Correct Answer: D

Rationale: The correct answer is D: Erythropoietin deficiency anemia. Chronic kidney disease often leads to anemia due to decreased production of erythropoietin. This hormone, produced by the kidneys, stimulates red blood cell production in the bone marrow. Iron-deficiency anemia (choice A) is more commonly caused by insufficient dietary iron intake or chronic blood loss. Vitamin B12 deficiency anemia (choice B) is usually due to inadequate dietary intake, malabsorption, or pernicious anemia. Aplastic anemia (choice C) is a bone marrow failure disorder characterized by pancytopenia (decreased red blood cells, white blood cells, and platelets) rather than a deficiency in erythropoietin production.

Correct Answer: A

Rationale: The correct answer is A: Evaluation. Evaluation in nursing care involves assessing the effectiveness of the care plan, identifying strengths, weaknesses, and areas for improvement. This step helps ensure that the patient's needs are being met appropriately. Planning (choice B) involves developing the care plan based on the assessment data. Implementation (choice C) is the step where the care plan is put into action. Assessment (choice D) is the initial step in the nursing process that involves collecting and analyzing data about the patient's health status.

Correct Answer: B

Rationale: The correct answer is B: Splenectomy. Splenectomy is the treatment of choice for hereditary spherocytosis as it helps prevent hemolysis and improve anemia. Removing the spleen reduces the destruction of the abnormal red blood cells. Choice A, Bone marrow transplant, is not a standard treatment for hereditary spherocytosis. Choice C, Frequent blood transfusions, may be used to manage anemia in some cases but is not the primary treatment for hereditary spherocytosis. Choice D, Liver biopsy, is not a treatment for hereditary spherocytosis; it is a procedure used to diagnose liver conditions, not related to this hematologic disorder.

Correct Answer: B

Rationale: The correct answer is B: Chest tube insertion. In the context of a pancreatic pseudocyst rupturing, a chest tube may be needed if the pseudocyst extends into the pleural space, leading to a pleural effusion. Choice A, paracentesis, involves the removal of fluid from the abdominal cavity, not the pleural space. Choice C, lumbar puncture, is a procedure performed to collect cerebrospinal fluid from the spinal canal, not relevant in this scenario. Choice D, biopsy of the pancreas, is not indicated in the immediate management of a ruptured pseudocyst.
