Correct Answer: B

Rationale: The most critical action to prioritize for ensuring patient safety during a cardiopulmonary exercise stress test is to monitor the patient's electrocardiogram (ECG) rhythm continuously during the test (Option B). This monitoring allows the healthcare team to promptly detect any abnormal heart rhythms or signs of cardiac distress, enabling timely intervention if necessary. Continuous ECG monitoring is essential during exercise testing as it helps in assessing the heart's response to physical activity and identifying any potential cardiac abnormalities or complications that may arise during the test. By closely monitoring the ECG rhythm, the nurse can ensure the patient's safety and well-being throughout the procedure. Administering a beta-blocker medication before the test (Option A) may be indicated in some cases but is not as crucial as continuous ECG monitoring during the test. Encouraging the patient to consume a heavy meal before the test (Option C) is contraindicated as it can interfere with the accuracy of the results

Correct Answer: B

Rationale: The formulation of a vision and mission statement in a health facility is an essential aspect of leadership and management. A well-crafted vision and mission statement provide the organization with a clear direction and purpose, guiding management and health personnel in their daily activities. It helps in aligning individual goals with organizational objectives, fostering teamwork, and enhancing overall performance. Effective leadership and management ensure that the vision and mission are communicated effectively, understood by all stakeholders, and implemented throughout the organization to achieve quality standards. By setting the tone for organizational culture and values, leadership and management play a crucial role in shaping the quality of care and services provided by the health facility.

Correct Answer: B

Rationale: The gallbladder is the structure responsible for storing and concentrating bile produced by the liver until it is needed for digestion. Bile is a digestive fluid that helps in the breakdown of fats during the digestive process. When food containing fats enters the small intestine, the gallbladder contracts and releases bile into the small intestine to aid in the digestion and absorption of fats. The gallbladder acts as a reservoir for bile, storing it until it is needed for digestion.

Correct Answer: A

Rationale: Acute pyelonephritis is the most likely condition based on the patient presentation and urinalysis findings described. Acute pyelonephritis is an infection of the renal parenchyma and pelvis, typically caused by ascending bacteria from the lower urinary tract. The classic symptoms include fever, chills, flank pain, and costovertebral angle tenderness (tenderness over the kidneys). The presence of pyuria (pus in the urine) and bacteriuria (bacteria in the urine) on urinalysis further supports the diagnosis of acute pyelonephritis. It is crucial to diagnose and treat acute pyelonephritis promptly to prevent complications and recurrent infections.

Correct Answer: D

Rationale: In the scenario described, the patient is presenting with severe symptoms of acute exacerbation of asthma, including severe dyspnea, accessory muscle use, and inability to speak in full sentences. In such cases, the most appropriate intervention for assessing the severity of the asthma exacerbation and guiding management decisions is a clinical assessment using standardized severity scores.
