Correct Answer: B

Rationale: One of the major differences between Hodgkin's lymphoma and non-Hodgkin's lymphoma is that Hodgkin's lymphoma is considered potentially curable, while non-Hodgkin's lymphoma is typically not curable. Hodgkin's lymphoma is characterized by the presence of Reed-Sternberg cells, which are not found in non-Hodgkin's lymphoma. Additionally, Hodgkin's lymphoma tends to spread in a more orderly and predictable manner through the lymph nodes, making it easier to treat and potentially cure with the appropriate combination of chemotherapy, radiation therapy, and stem cell transplant. On the other hand, non-Hodgkin's lymphoma is a diverse group of lymphomas that can vary greatly in presentation, behavior, and response to treatment, with some subtypes being more aggressive and resistant to treatment. Therefore, the potential for cure is higher in Hodgkin's lymphoma compared to non-Hodgkin's lymph

Correct Answer: A

Rationale: Aplastic anemia is a condition characterized by a reduction in the number of all three blood cell types: red blood cells, white blood cells, and platelets. The patient's presentation of bone pain, fatigue, frequent infections, pancytopenia (decreased counts of all blood cell types), hypocellular bone marrow (reduced cellularity in the bone marrow), and absence of reticulocytes is indicative of aplastic anemia.

Correct Answer: B

Rationale: Tiotropium (Spiriva) is an anticholinergic bronchodilator used for the management of COPD. A common side effect of anticholinergic medications is dry mouth. Rinsing the mouth with water after using the inhaler can help reduce the risk of developing oral thrush or other mouth infections due to dryness. This instruction helps promote good oral hygiene and decreases the potential side effects associated with tiotropium inhaler use. This teaching is important for patients to follow to ensure their overall health and well-being while using the medication.

Correct Answer: C

Rationale: The esophagus is responsible for propelling food from the oral cavity to the stomach through a series of coordinated muscular contractions. These contractions are known as peristalsis. The esophagus is a muscular tube connecting the throat (pharynx) to the stomach and plays a crucial role in moving food bolus from the mouth to the stomach for digestion. The tongue helps in the chewing and swallowing of food, the pharynx is involved in the passage of food and air, and the epiglottis helps prevent food from entering the airways during swallowing. However, it is the esophagus that actively moves the food to the stomach.

Correct Answer: D

Rationale: The constellation of symptoms presented (periorbital edema, hypertension, proteinuria) along with the laboratory findings (elevated creatinine and urea levels, hyperkalemia, metabolic acidosis) are classical signs of chronic kidney disease (CKD). In CKD, the kidneys gradually lose their function over time, leading to impaired filtration of waste products and electrolyte imbalance. The presence of hypertension and proteinuria are common in CKD due to the compromised renal function. Additionally, elevated serum creatinine and urea levels, hyperkalemia, and metabolic acidosis are indicative of kidney dysfunction.
