Haemolytic anemia is not produced by:

Correct Answer: B

Rationale: The correct answer is B: lithium. Lithium is not known to cause haemolytic anemia. Penicillin (A), Quinidine (C), and methyldopa (D) are associated with causing haemolytic anemia due to various mechanisms, such as immune-mediated destruction of red blood cells. In contrast, lithium is primarily used to treat mood disorders and does not have a direct link to causing haemolytic anemia. Therefore, by process of elimination and understanding the pharmacological effects of these drugs, we can determine that lithium is the correct answer.

Correct Answer: B

Rationale: The correct answer is B: pancreatitis. Sickle cell anemia does not typically manifest with pancreatitis. The pathophysiology of sickle cell anemia involves sickle-shaped red blood cells leading to vaso-occlusive crises, resulting in complications such as papillary necrosis, osteomyelitis, and congestive heart failure. Pancreatitis is not a common complication of sickle cell anemia due to the absence of significant involvement of the pancreas in the disease process. Therefore, option B is the correct choice, as it does not align with the typical complications seen in sickle cell anemia.

Correct Answer: D

Rationale: Step-by-step rationale: 1. Macrocytosis refers to larger-than-normal red blood cells. 2. Systemic Lupus Erythematosus (SLE) is not typically associated with macrocytosis. 3. Anemia of myxedema, methotrexate-induced, and chronic alcoholism-induced liver disease can all lead to macrocytosis. 4. Therefore, the correct answer is D: SLE, as it is not commonly associated with macrocytosis.

Correct Answer: A

Rationale: The correct answer is A: Hypercalcemia. In multiple myeloma, bone destruction releases calcium into the bloodstream, leading to hypercalcemia. This can result in symptoms like excessive thirst, fatigue, confusion, and kidney issues. Hyperproteinemia (B) is not typically associated with multiple myeloma. Elevated serum viscosity (C) is more related to conditions like Waldenström macroglobulinemia, not multiple myeloma. Elevated RBC count (D) is not a common finding in multiple myeloma and is more suggestive of polycythemia vera.

Correct Answer: A

Rationale: The correct answer is A: Chew with care to avoid inadvertently biting the tongue. Stomatitis causes mouth sores, making it crucial for the patient to be cautious while chewing to prevent accidental injury to the mouth. This helps in reducing pain and promoting healing. Choice B is incorrect because using the oral anesthetic 1 hour prior to mealtime may not provide immediate relief during eating. Choice C is incorrect as brushing teeth before and after eating can irritate the mouth sores further. Choice D is incorrect as swallowing slowly and deliberately does not address the issue of preventing accidental biting of the tongue.
