HESI 799 RN Exit Exam Questions
Question 1 of 5
A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which assessment finding is most concerning?
Correct Answer: C
Rationale: The correct answer is C: Peaked T waves on the ECG. In hyperkalemia, elevated potassium levels can affect the heart's electrical activity, leading to changes on the ECG such as peaked T waves. This finding is concerning as it can progress to serious cardiac arrhythmias, including ventricular tachycardia and fibrillation. Bradycardia (choice A) and decreased deep tendon reflexes (choice D) are not typically associated with hyperkalemia. While muscle weakness (choice B) can occur in hyperkalemia due to its effect on neuromuscular function, the most concerning assessment finding indicating the need for immediate intervention in this scenario is peaked T waves on the ECG.
Question 2 of 5
A client with a history of atrial fibrillation is admitted with a new onset of confusion. Which laboratory value should the nurse monitor closely?
Correct Answer: A
Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client with atrial fibrillation to assess the effectiveness and safety of anticoagulation therapy with warfarin. Monitoring the INR helps to ensure that the client is within the therapeutic range to prevent complications such as thrombosis or bleeding. Choices B, C, and D are less relevant in this scenario. While serum glucose levels are important in assessing metabolic status, and white blood cell count and prothrombin time are important indicators for other conditions, they are not the primary focus when a client with atrial fibrillation presents with confusion.
Question 3 of 5
In a client with cirrhosis admitted with jaundice and ascites, which laboratory value is most concerning?
Correct Answer: C
Rationale: A serum ammonia level of 80 mcg/dl is most concerning in a client with cirrhosis as it may indicate hepatic encephalopathy, requiring immediate intervention. Elevated ammonia levels are associated with impaired liver function and can lead to mental status changes. Serum bilirubin (Choice A) is elevated in cirrhosis but not as concerning for acute intervention as high ammonia levels. Serum albumin (Choice B) and serum sodium (Choice D) levels are important in cirrhotic patients but are not as directly associated with hepatic encephalopathy as ammonia levels.
Question 4 of 5
A client with chronic kidney disease (CKD) is admitted with hyperkalemia. Which intervention should the nurse implement first?
Correct Answer: B
Rationale: The correct answer is to administer intravenous insulin and glucose first. This intervention helps drive potassium back into the cells, lowering serum levels effectively. Administering intravenous calcium gluconate (choice A) is used to stabilize cardiac membranes in severe hyperkalemia but does not address the underlying cause. Administering intravenous sodium bicarbonate (choice C) is used in metabolic acidosis, not hyperkalemia. Administering a loop diuretic (choice D) can help eliminate potassium but is not the first-line treatment for hyperkalemia in CKD.
Question 5 of 5
The nurse is caring for a client with end-stage renal disease (ESRD) who is scheduled for hemodialysis. Which clinical finding is most concerning?
Correct Answer: C
Rationale: The correct answer is C. A fever of 100.4°F is most concerning in a client with ESRD scheduled for hemodialysis because it may indicate an underlying infection that requires immediate attention. Elevated body temperature can be a sign of systemic infection, which can quickly worsen in individuals with compromised renal function. Monitoring for infection is crucial in ESRD patients to prevent complications. Choices A, B, and D are not as immediately concerning in this context. While variations in blood pressure, heart rate, and respiratory rate should be monitored, they are not as indicative of a potentially severe issue as an unexplained fever in this scenario.
