Correct Answer: D

Rationale: The patient is presenting with symptoms and laboratory findings consistent with a paraneoplastic syndrome related to Hodgkin lymphoma. In this case, the fever, chills, generalized malaise, pancytopenia, circulating Reed-Sternberg cells, and bone marrow involvement are all indicative of a paraneoplastic syndrome associated with Hodgkin lymphoma. Paraneoplastic syndromes are a group of disorders that are triggered by an abnormal immune response to a neoplasm, such as Hodgkin lymphoma, leading to various systemic manifestations.

Correct Answer: D

Rationale: The Philippine Regulatory Commission - Board of Nursing (PRC-BON) has the power to regulate nursing practice in the Philippines.

Correct Answer: C

Rationale: Hypokalemia (low levels of potassium) increases the risk of digoxin toxicity. This is because digoxin competes with potassium for binding sites on the sodium-potassium ATPase pump in the cell membrane. When potassium levels are low, there is an increased binding of digoxin to these pumps, leading to enhanced entry of calcium into the cells. This can result in an increased intracellular calcium concentration, leading to digoxin toxicity and potential cardiac arrhythmias. Therefore, monitoring and correcting potassium levels is crucial in patients prescribed digoxin to reduce the risk of toxicity.

Correct Answer: C

Rationale: One of the main consequences of hypoxemia, which is low oxygen levels in the blood, is decreased oxygen saturation. Oxygen saturation refers to the percentage of hemoglobin molecules in the blood that are bound to oxygen. When there is insufficient oxygen in the blood due to hypoxemia, the oxygen saturation levels will drop. This can lead to symptoms such as shortness of breath, confusion, rapid heart rate, and ultimately can result in tissue damage if not corrected promptly. Monitoring oxygen saturation levels is crucial in the immediate post-operative phase to ensure adequate ventilation and oxygenation for the patient's recovery.

Correct Answer: C

Rationale: The presentation described with a sensation of fullness and pressure in the left ear, along with hearing loss and occasional tinnitus, and the findings of a retracted tympanic membrane with decreased mobility on pneumatic otoscopy are most consistent with serous otitis media, also known as otitis media with effusion (OME). OME is characterized by the presence of non-infected fluid in the middle ear space, leading to symptoms such as ear fullness, hearing loss, and occasionally tinnitus.
