Patient with Hodgkin lymphoma, radiation to groin, Risk for Impaired Tissue Integrity. Delegate to nursing assistant?

Correct Answer: D

Rationale: The correct answer is D because cleaning the skin with mild soap is within the nursing assistant's scope of practice and is essential for maintaining skin integrity in patients receiving radiation therapy. Checking skin for redness/peeling (A) and explaining skin care (C) involve assessment and education, which should be done by a registered nurse. Assisting with clothing choice (B) is not directly related to preventing impaired tissue integrity. In summary, choice D is correct as it addresses the immediate need for skin care within the nursing assistant's role, while the other choices involve tasks beyond their scope or not directly related to the issue at hand.

Correct Answer: A

Rationale: The correct answer is A: Microtubules. Microtubules are structural components of the cytoskeleton that help maintain the shape of a cell by providing support and stability. They also play a crucial role in cell division, intracellular transport, and cell motility. Spindle fibers are involved in cell division, ribosomes are responsible for protein synthesis, and centrioles are involved in organizing the microtubules during cell division. Therefore, the correct choice is A as it directly relates to maintaining cell shape.

Correct Answer: B

Rationale: The correct answer is B: Trypanosoma brucei gambiense. This parasite causes African Trypanosomiasis (sleeping sickness), characterized by fever, lymphadenopathy, and neurological symptoms. Choice A, Trypanosoma cruzi, causes Chagas disease, not presenting with lymphadenopathy. Choice C, Leishmania donovani, causes visceral leishmaniasis with hepatosplenomegaly, not cervical lymphadenopathy. Choice D, Onchocerca volvulus, causes onchocerciasis (river blindness) with skin and eye manifestations, not cervical lymphadenopathy.

Correct Answer: B

Rationale: The correct answer is B: Basophilic stippling. Basophilic stippling is a finding seen in blood smears of individuals with hookworm infection anemia. It represents aggregates of ribosomes in red blood cells due to lead poisoning or thalassemia. Howell-Jolly bodies (A) are nuclear remnants in red blood cells, typically seen in conditions causing splenic dysfunction. Target cells (C) are seen in liver disease or hemoglobinopathies. Spherocytes (D) are seen in conditions like hereditary spherocytosis or autoimmune hemolytic anemia.

Correct Answer: D

Rationale: The correct answer is D, "RA with excess blasts in transformation". This choice indicates progression to acute myeloid leukemia, which has the poorest prognosis among MDS subtypes. Refractory anemia (A) has a relatively better prognosis compared to transformation. RA with ring sideroblasts (B) and RA with excess blasts (C) are also MDS subtypes, but they do not indicate the same level of disease progression as RA with excess blasts in transformation. Therefore, choice D is the correct answer due to its association with the most severe outcome in MDS.
