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: A

Rationale: The incident report is the best source of factual information to investigate the fall further. Incident reports are official documents that provide a detailed account of what happened leading up to and during an incident. They include factual information such as the date, time, location, individuals involved, and details of the event. By reviewing the incident report, investigators can gather accurate information to determine the cause of the fall and any contributing factors. This document serves as an essential tool in conducting a thorough investigation into the fall and helps in identifying preventive measures to avoid similar incidents in the future.

Correct Answer: C

Rationale: In the case of Mang Luis, who has been diagnosed with chronic obstructive pulmonary disease (COPD) and is experiencing exacerbation, the most crucial health intervention to include in the teaching plan is to reduce the risk for infection. COPD exacerbations are commonly triggered by respiratory infections such as pneumonia and bronchitis. Preventing infections is essential in managing COPD as they can lead to worsening of symptoms and increased healthcare utilization. Therefore, educating Mang Luis on strategies to reduce the risk of infection, such as proper hand hygiene, avoiding exposure to sick individuals, getting vaccinated, and managing environmental factors, is paramount in his care plan.

Correct Answer: B

Rationale: Spondylosis is a condition characterized by degenerative changes in the intervertebral discs, leading to narrowing of the disc space and the formation of osteophytes (bone spurs). This degenerative process commonly occurs with aging and can cause symptoms such as neck or back pain, stiffness, and reduced range of motion. Spondylosis is a common finding on imaging studies like X-rays and MRI scans in individuals over the age of 50 and is a natural part of the aging process of the spine.

Correct Answer: C

Rationale: The last and necessary part of any activity should involve an evaluation process. By evaluating the activity, the organizers can gather feedback on what worked well and what areas need improvement. This feedback is crucial for enhancing future activities that are similar in nature. It allows for reflections on the effectiveness of the activity, identifies strengths and weaknesses, and helps in making necessary adjustments for better outcomes in the future. Overall, evaluation ensures continuous improvement and development in organizing successful activities.
