Correct Answer: B

Rationale: Generalizability refers to the extent to which research findings and conclusions can be applied beyond the specific conditions of the study to a larger population or different settings. In this case, if the findings of a study on patients with myocardial infarction (MI) under stress can be applied to all such patients in the whole Philippines, it indicates that the study results are generalizable beyond the specific sample studied. Therefore, the criteria satisfied in this context is generalizability.

Correct Answer: A

Rationale: In a community clinic providing primary care for patients, the most common healthcare professional who manages patient care is a physician. Physicians, also known as doctors, are trained and licensed to diagnose and treat a wide range of medical conditions. They are responsible for conducting exams, prescribing medications, ordering tests, and developing treatment plans for patients. While other healthcare professionals such as nurses, midwives, and barangay health workers also play important roles in providing care, physicians typically lead the team, make critical decisions, and provide overall management of patient care in a primary care setting like a community clinic.

Correct Answer: C

Rationale: The submandibular gland is located inferior and posterior to the mandible. It produces a mixed type of saliva, which is primarily serous (enzyme-rich) but also contains some mucous components. This gland plays a significant role in digestion, as its serous saliva contains enzymes such as amylase that help break down carbohydrates in the mouth before they reach the stomach.

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: Sevelamer is a medication commonly prescribed to reduce serum phosphate levels in patients with chronic kidney disease. Sevelamer is a phosphate binder that works by binding to dietary phosphate in the gut, preventing its absorption into the bloodstream. By reducing serum phosphate levels, sevelamer helps manage complications associated with hyperphosphatemia in chronic kidney disease patients, such as mineral and bone disorders. Other medications like epoetin alfa are used to treat anemia commonly seen in chronic kidney disease patients, while cinacalcet is used to manage secondary hyperparathyroidism. Allopurinol, on the other hand, is used to treat gout by reducing uric acid levels and is not indicated for reducing serum phosphate levels in chronic kidney disease patients.
