Correct Answer: A

Rationale: The correct answer is to monitor the onset of pulmonary edema. In cases of aspirin overdose, metabolic acidosis is a common consequence that can lead to the development of pulmonary edema. Early signs of aspirin poisoning include symptoms like tinnitus, hyperventilation, vomiting, dehydration, and fever. Late signs may manifest as drowsiness, bizarre behavior, unsteady walking, and coma. Aspirin poisoning can cause abnormal breathing that is typically rapid and deep. Pulmonary edema may occur due to increased capillary permeability in the lungs, leading to the leakage of proteins and fluid transudation in renal and pulmonary tissues. Changes in renal tubule permeability can also affect colloid osmotic pressure, potentially contributing to pulmonary edema. Monitoring pulmonary edema is crucial in managing aspirin overdose cases to prevent further complications. Choices B, C, and D are incorrect because metabolic alkalosis, respiratory alkalosis, and Parkinson's disease type symptoms are not typically associated with aspirin overdose and are not primary concerns in its acute management.

Correct Answer: D

Rationale: A CT scan is most likely to be performed in this scenario. A CT scan would be done to further investigate the cause of the left hemiparesis. Noncontrast CT scanning is commonly used in the acute evaluation of patients with suspected acute stroke to assess for ischemic changes or hemorrhage in the brain. While a CBC may provide information on blood cell counts and general health status, it is not the primary test for evaluating hemiparesis. An ECG is used to assess heart function and rhythm, which is not the main concern in this case. Thyroid function tests evaluate thyroid hormone levels and are not typically the initial tests for evaluating hemiparesis and confusion.

Correct Answer: A

Rationale: Telemetry is used to monitor the cardiac rhythms of clients with potentially unstable conditions or those rhythms that affect activities. Clients with syncope potentially related to cardiac dysrhythmia require continuous monitoring to detect any potential life-threatening dysrhythmias. Unstable angina can be monitored in a telemetry unit, but syncope with potential cardiac causes takes precedence. Clients with sinus rhythm and PVCs may not necessitate telemetry unless there are further indications of instability. A client who had a myocardial infarction 6 hours ago is typically monitored in an intensive care unit rather than a telemetry unit.

Correct Answer: A

Rationale: The correct answer is bowel perforation. Bowel perforation is the most serious complication of fiberoptic colonoscopy, with signs such as progressive abdominal pain, fever, chills, and tachycardia indicating advancing peritonitis. Although colonoscopic perforation is rare (0.03% to 0.7% incidence), it can lead to high mortality and morbidity rates. Viral gastroenteritis (Choice B) typically presents with symptoms like diarrhea, nausea, vomiting, and abdominal cramps, but it is not the most immediate concern in this scenario. Colon cancer (Choice C) and diverticulitis (Choice D) are important conditions but are less likely to present acutely after colonoscopy compared to bowel perforation.

Correct Answer: D

Rationale: The correct answer is D: Left ventricular functioning. The purpose of inserting a pulmonary artery catheter is to obtain information about left ventricular functioning when the catheter balloon is inflated. Choices A, B, and C are incorrect because while a pulmonary artery catheter can provide information on stroke volume, cardiac output, and venous pressure, its primary purpose is to assess left ventricular function.
