Correct Answer: D

Rationale: Quantitative research is the type of research that involves collecting numerical data, which can be easily quantified and analyzed statistically. It is characterized by its structured methodology, objectivity, and the ability to control variables to a considerable extent. In the context of a study on sleep, where data related to sleep patterns, duration, quality, etc., need to be measured and analyzed in a systematic manner, quantitative research would be the most appropriate choice. This type of research allows for a more precise understanding of the relationships and patterns within the data, providing valuable insights into the sleep-related factors being studied.

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: D

Rationale: The presentation of sudden-onset severe headache, vomiting, and altered mental status, along with the presence of a berry-shaped aneurysm on imaging, point towards a diagnosis of subarachnoid hemorrhage. The most common cause of a subarachnoid hemorrhage is the rupture of a saccular (berry) aneurysm, which commonly occurs at the junction of the anterior communicating artery and anterior cerebral artery. The sudden headache is often described as the "worst headache of my life" and is typically associated with nausea and vomiting. Altered mental status may be present due to the effects of increased intracranial pressure and possible associated brain injury. It is important to promptly diagnose and manage subarachnoid hemorrhage to prevent complications such as vasospasm, rebleeding, and ischemic deficits.

Correct Answer: C

Rationale: If the nurse notices that the patient's arms are not adequately padded while positioning for surgery, the nurse should immediately take action to prevent pressure injuries. Applying soft padding to the patient's arms will help distribute the pressure more evenly, reducing the risk of skin breakdown and potential harm to the patient during the surgical procedure. It is essential to prioritize the patient's safety and comfort in such situations. Simply proceeding with the positioning as planned could lead to complications, so addressing the inadequate padding promptly is the appropriate course of action.

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.
