HESI 799 RN Exit Exam Quizlet

Correct Answer: A

Rationale: Corrected Rationale: An electrocardiogram (ECG) should be performed first to assess for cardiac ischemia in a client with a history of myocardial infarction and chest pain. An ECG provides immediate information about the heart's electrical activity, helping to identify changes indicative of cardiac ischemia or infarction. Chest X-ray (Choice B) is not the initial diagnostic test for assessing chest pain related to myocardial infarction. Arterial blood gases (Choice C) are used to assess oxygenation and acid-base balance but are not the primary diagnostic test for myocardial infarction. An echocardiogram (Choice D) may provide valuable information about cardiac structure and function, but it is not the first-line diagnostic test for acute chest pain in a client with a history of myocardial infarction.

Correct Answer: D

Rationale: The correct first intervention for a client with heart failure who is on a low sodium diet and reports a significant weight gain is to assess the client for signs of fluid overload. This step is crucial in determining the severity of the situation and guiding further treatment. In this scenario, assessing for signs of fluid overload takes priority over other actions such as instructing the client to reduce fluid intake, monitoring intake and output, or administering a diuretic. While these actions may be necessary depending on the assessment findings, the initial priority is to evaluate the client's immediate condition.

Correct Answer: C

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with DKA as it may indicate worsening hyperkalemia, requiring immediate intervention. Elevated serum potassium levels can lead to life-threatening cardiac arrhythmias. While elevated glucose and low bicarbonate are characteristic of DKA, hyperkalemia poses a higher immediate risk. Serum sodium within the normal range is not typically a primary concern in DKA.

Correct Answer: C

Rationale: In a client with cirrhosis presenting with jaundice and ascites, yellowing of the skin (icterus) is the most concerning assessment finding. This indicates significant liver dysfunction and a high level of bilirubin in the blood. Yellowing of the skin suggests a severe impairment of the liver's ability to process bilirubin, which can lead to serious complications. Peripheral edema and increased abdominal girth are common manifestations of cirrhosis but are not as acutely concerning as skin yellowing. Confusion and altered mental status are also critical findings in cirrhosis, indicating hepatic encephalopathy, but skin yellowing is more closely associated with the severity of liver dysfunction in this scenario.

Correct Answer: D

Rationale: The correct answer is D. Clear breath sounds indicate that the pneumonia is resolving and the treatment is effective. Breath sounds are often muffled or crackling in pneumonia due to the presence of fluid or inflammation in the lungs. Clear breath sounds suggest that the air is moving freely through the lungs, indicating improvement. Choices A, B, and C are less specific indicators of pneumonia resolution. While less chest pain and a decreasing white blood cell count can be positive signs, they are not as direct in indicating the effectiveness of pneumonia treatment as the presence of clear breath sounds. A decreased respiratory rate could be seen in various conditions and may not solely indicate the resolution of pneumonia.
