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: Conducting a year-end performance evaluation of the staff is an example of a controlling function in management. Controlling involves monitoring and evaluating the performance of employees to ensure that they are working effectively and meeting the set goals and standards. By assessing the staff's performance at the end of the year, managers can identify areas of improvement, provide feedback, and make necessary adjustments to ensure the overall success of the organization. Hence, the process of evaluating staff performance falls under the controlling function of management.

Correct Answer: A

Rationale: The given patient's symptoms of chest pain that occurs during heavy lifting or physical exertion and is relieved by rest are consistent with stable angina. Stable angina is characterized by predictable chest pain that occurs with exertion and is typically relieved by rest or nitroglycerin. The transient ST-segment depression on ECG is also a common finding in patients with stable angina, which reflects myocardial ischemia during episodes of chest pain triggered by exertion. In contrast, unstable angina is characterized by chest pain at rest or with minimal exertion that is of increasing frequency, severity, or duration. Acute myocardial infarction is associated with persistent ST-segment elevation or new Q-waves on ECG, and Prinzmetal's angina is characterized by chest pain at rest due to coronary artery spasm rather than exertion.

Correct Answer: A

Rationale: The presentation described in the question is characteristic of tinea versicolor, a fungal skin infection caused by Malassezia furfur. The hypopigmented macules with fine scaling are often seen on the trunk and proximal extremities, particularly in areas that are more prone to sebum production. Patients with tinea versicolor may have a history of sun exposure and outdoor activities as the organism responsible for the infection thrives in warm, humid environments. Treatment typically involves the use of topical antifungal agents such as ketoconazole or selenium sulfide.

Correct Answer: B

Rationale: When a patient with chronic kidney disease is prescribed erythropoietin-stimulating agents (ESAs) for anemia management, the parameter that should be monitored closely by the nurse is the hemoglobin levels. Hemoglobin levels indicate the patient's response to ESA therapy and are essential in assessing the effectiveness of the treatment in addressing anemia. Monitoring hemoglobin levels helps ensure that the patient's anemia is controlled within the target range to avoid both the risks of under-treatment (resulting in persistent anemia) and over-treatment (increased risk of adverse outcomes such as hypertension, stroke, or cardiovascular events).
