HESI RN Exit Exam 2024 Quizlet

Correct Answer: C

Rationale: The correct answer is C. A potassium level of 6.5 mEq/L is dangerously high, a condition known as hyperkalemia, and requires immediate intervention to prevent cardiac complications. Hyperkalemia can lead to life-threatening arrhythmias, making it crucial to notify the healthcare provider promptly. Choices A, B, and D do not indicate immediate life-threatening conditions. Elevated serum creatinine levels are expected in CKD, a hemoglobin level of 10 g/dl is within a reasonable range, and a blood glucose level of 150 mg/dl is not acutely concerning in this context.

Correct Answer: A

Rationale: The correct answer is A. Anuria for the last 12 hours. Anuria, the absence of urine output, indicates complete kidney failure and is a medical emergency that requires immediate attention. In acute kidney injury (AKI), the kidneys are unable to filter waste from the blood effectively, leading to a buildup of toxins and electrolyte imbalances like elevated blood potassium levels. Tachycardia and hypotension (choice B) can be seen in AKI but do not reflect the urgency of addressing anuria. Decreased urine output (choice C) is concerning but not as critical as the absence of urine production. Elevated blood urea nitrogen (BUN) levels (choice D) are indicative of kidney dysfunction but do not demand immediate action as anuria does.

Correct Answer: A

Rationale: The correct answer is A: History of alcohol use. In this scenario, obtaining the history of alcohol use is crucial as it could indicate withdrawal, which might explain the client's confusion. Alcohol withdrawal can lead to symptoms such as confusion, agitation, and disorientation. While knowing the current medication list (choice B) is important for overall patient care, in this case, alcohol withdrawal is a more likely cause of the confusion. Baseline cognitive status (choice C) is valuable for comparison but may not directly explain the sudden confusion. Family history of dementia (choice D) is less relevant in this acute situation compared to the potential immediate impact of alcohol withdrawal.

Correct Answer: A

Rationale: A serum potassium level of 6.0 mEq/L is most concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, which can lead to serious cardiac complications such as arrhythmias and cardiac arrest. Immediate intervention is required to lower potassium levels. Choice B, serum creatinine of 2.5 mg/dL, is elevated but expected in ESRD due to impaired kidney function. Choice C, serum calcium of 8.0 mg/dL, is within the normal range and not typically a priority in this situation. Choice D, hemoglobin of 10 g/dL, is slightly low but not an immediate concern for a client scheduled for hemodialysis unless significantly lower and causing severe symptoms.

Correct Answer: A

Rationale: A white blood cell count of 2,000/mm� is critically low and places the client at high risk for infection, requiring immediate intervention. Neutropenia, a low white blood cell count, is a common side effect of chemotherapy. A decreased white blood cell count compromises the immune system's ability to fight infections, making it a priority to address to prevent serious complications. Platelet count of 100,000/mm� is relatively low but not as urgent as a severely low white blood cell count. Hemoglobin level of 10 g/dL is within the normal range for females and does not require immediate intervention. Serum creatinine level of 1.5 mg/dL is also within the normal range and does not pose an immediate threat to the client's health.
