HESI 799 RN Exit Exam

1. A client with a history of chronic heart failure is admitted with shortness of breath. Which diagnostic test should the nurse anticipate preparing the client for first?

Correct answer: C

Rationale: The correct answer is an echocardiogram. This diagnostic test is crucial in assessing ventricular function and identifying the cause of shortness of breath in a client with heart failure. It provides valuable information about the heart's structure, function, and blood flow. While a chest X-ray may show signs of heart failure, it does not directly assess cardiac function like an echocardiogram does. Arterial blood gases (ABGs) are useful to evaluate oxygenation and acid-base balance but do not provide information specific to heart function. An electrocardiogram (ECG) assesses the heart's electrical activity and rhythm, which is important but may not provide the detailed structural information needed in this scenario.

2. 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.

3. 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.

4. The nurse is caring for a client with acute respiratory distress syndrome (ARDS) who is receiving mechanical ventilation. Which assessment finding requires immediate intervention?

Correct answer: C

Rationale: The correct answer is C. A tidal volume of 300 ml is concerning in a client with ARDS on mechanical ventilation because it indicates hypoventilation, which can lead to inadequate gas exchange and worsening respiratory status. This finding requires immediate intervention to optimize ventilation and oxygenation. Options A, B, and D are not as critical in this scenario. An oxygen saturation of 90% may be acceptable depending on the client's baseline condition and the target range set by the healthcare provider. A respiratory rate of 28 breaths per minute is slightly elevated but may not be immediately alarming. A blood pressure of 110/70 mmHg is within normal limits and does not require urgent intervention.

5. Which breakfast selection indicates that the client understands the nurse's instructions about the dietary management of osteoporosis?

Correct answer: D

Rationale: The correct answer is D, 'Bagel with jelly and skim milk.' This choice includes skim milk, a good source of calcium, which is important for osteoporosis management. It also avoids foods that inhibit calcium absorption. Osteoporosis dietary management emphasizes increased calcium intake and reducing foods that hinder calcium absorption. Choice A only provides proteins but lacks calcium. Choice B offers fruits and a bran muffin, but it lacks a good source of calcium. Choice C has granola but misses a significant source of calcium.
