A client has a bone marrow biopsy done. Which nursing intervention is the priority post procedure?

Correct Answer: A

Rationale: The correct answer is A: Applying pressure to the biopsy site. This is the priority post-procedure as it helps prevent bleeding and hematoma formation. Applying pressure aids in achieving hemostasis, reducing the risk of complications. Choice B is incorrect as inspecting for ecchymoses is important but not the priority over preventing bleeding. Choice C is also incorrect as sending specimens to the lab can be done after ensuring the client's safety. Choice D is incorrect as teaching about avoiding vigorous activity is important but not the immediate priority post-procedure.

Correct Answer: A

Rationale: The correct treatment option for Wilson's disease is A: Penicillamine. Penicillamine is a chelating agent that helps remove excess copper from the body. It binds to copper, forming a stable complex that can be excreted in the urine. Riboflavin (B) is a vitamin and not used in Wilson's disease treatment. Trientine (C) is another chelating agent used in Wilson's disease treatment but is not as commonly prescribed as penicillamine. Potassium disulfide (D) is not a recognized treatment for Wilson's disease.

Correct Answer: B

Rationale: The correct answer is B: Dipyridamole. Dipyridamole works by inhibiting the enzyme phosphodiesterase, leading to an increase in cyclic adenosine monophosphate (cAMP) levels. This increase in cAMP levels potentiates the effect of prostacyclins, which inhibit platelet stickiness and decrease platelet adhesion to thrombogenic surfaces. Rationale: A: Sulfinpyrazone is a uricosuric agent, not a platelet anti-aggregant. C: Ticlopidine and D: Clopidogrel are both antiplatelet agents but work by different mechanisms (ADP receptor antagonists). They do not potentiate prostacyclins and do not directly affect cAMP levels.

Correct Answer: B

Rationale: The correct answer is B because Chronic Lymphocytic Leukemia (CLL) is characterized by the gradual accumulation of small mature B cells in the blood and bone marrow. B cells are lymphocytes that play a key role in the immune system. Choice A (T cells) is incorrect because CLL primarily involves B cells, not T cells. Choice C (NK cells) is incorrect because CLL does not involve natural killer (NK) cells. Choice D (Mixed) is incorrect because CLL is characterized by the accumulation of a single type of cell, specifically mature B cells.

Correct Answer: D

Rationale: Correct Answer: D Rationale: 1. During the mesoblastic phase of erythropoiesis in the yolk sac, only erythroblasts develop. 2. Erythroblasts are precursors of red blood cells and are responsible for producing hemoglobin. 3. Other choices (A, B, C) mention specific types of hemoglobins or cells that are not directly related to the mesoblastic phase. 4. Hb F, Hg A2, Hg A are adult hemoglobin types, Gower 1 and Gower 2 are embryonic hemoglobins, and Portland Hgb is an abnormal hemoglobin. 5. Therefore, the correct answer is D because only erythroblasts develop from yolk sacs during the mesoblastic phase.
