67-year-old with chemotherapy-induced thrombocytopenia. Which statement is of most concern?

Correct Answer: C

Rationale: The correct answer is C because taking aspirin can worsen thrombocytopenia by further reducing platelet function, leading to increased risk of bleeding. Aspirin is a known blood thinner and can exacerbate the condition in a patient with low platelet count. Choices A, B, and D are not as concerning because bruising easily, soft dark bowel movements, and decreased appetite can be common side effects of chemotherapy and not directly related to worsening thrombocytopenia.

Correct Answer: C

Rationale: The correct answer is C: SS. In sickle cell anemia, the genetic pattern is homozygous for the sickle cell gene (HbS), resulting in the genotype SS. This means both copies of the hemoglobin gene are mutated, leading to the production of abnormal hemoglobin. Choice A (AS) indicates a carrier of the sickle cell trait with one normal and one mutated gene. Choice B (AA) represents a normal individual with two normal hemoglobin genes. Choice D (AF) is an incorrect combination as there is no such genetic pattern associated with sickle cell anemia.

Correct Answer: D

Rationale: The correct answer is D because Hodgkin lymphoma B symptoms include all of the above. A - Loss of weight can be a symptom due to metabolic changes. B - Drenching night sweats are common in Hodgkin lymphoma. C - Fever without infection is a classic B symptom. Therefore, all three symptoms are characteristic of Hodgkin lymphoma B symptoms.

Correct Answer: D

Rationale: The correct answer is D: T lymphocyte. T lymphocytes require IL-2 and IL-4 for conversion to mature circulating cells. IL-2 is crucial for T cell proliferation and differentiation, while IL-4 is essential for promoting T cell growth and differentiation into effector cells. Neutrophils (A) mature in the bone marrow, Eosinophils (B) primarily develop in response to IL-5, and B lymphocytes (C) mature in the bone marrow and require IL-7 for development.

Correct Answer: C

Rationale: The correct answer is C: Quinine and clindamycin. Quinine is recommended for treating malaria in pregnant women due to its safety profile during pregnancy. Clindamycin is often used in combination with quinine to enhance efficacy and reduce the risk of parasite resistance. - A (Atovaquone and proguanil) is contraindicated in pregnancy due to limited safety data. - B (Quinine and doxycycline) is not recommended in pregnant women as doxycycline can cause adverse effects on fetal development. - D (Mefloquine) is generally not recommended in pregnancy due to potential risks to the fetus.
