NCLEX RN Exam Review Answers
1. The child with hemolytic-uremic syndrome is anuric and will undergo peritoneal dialysis. Which measure should the nurse implement?
- A. Restrict fluids as prescribed.
- B. Care for the arteriovenous fistula.
- C. Encourage foods high in potassium.
- D. Administer analgesics as prescribed.
Correct answer: Restrict fluids as prescribed.
Rationale: In hemolytic-uremic syndrome, often associated with bacterial toxins and viruses, acute kidney injury occurs in children, leading to symptoms like anemia, thrombocytopenia, renal injury, and CNS symptoms. For an anuric child with hemolytic-uremic syndrome undergoing peritoneal dialysis, fluid restriction is vital to prevent fluid overload. Pain management is not directly related to hemolytic-uremic syndrome. Foods high in potassium should be limited, not encouraged, due to impaired kidney function. Peritoneal dialysis does not involve an arteriovenous fistula, which is specific to hemodialysis.
2. Diabetic patients are more prone to ____________ than other people without this chronic disorder.
- A. infection
- B. increased oxygen saturation
- C. low fibrinogen
- D. constipation
Correct answer: infection
Rationale: Diabetic patients are more prone to infection than other people without this chronic disorder. Diabetes weakens the immune system and impairs the body's ability to fight off infections, making individuals with diabetes more susceptible to various types of infections. Increased oxygen saturation, low fibrinogen, and constipation are not directly related to diabetes or the increased infection risk associated with the condition. Increased oxygen saturation is actually a positive health indicator, low fibrinogen levels are not a common issue in diabetes, and constipation is not a primary concern when comparing diabetic patients to others without the condition.
3. The healthcare provider is managing a 20 lbs (9 kg) 6-month-old with a 3-day history of diarrhea, occasional vomiting, and fever. Peripheral intravenous therapy has been initiated, with 5% dextrose in 0.33% normal saline with 20 mEq of potassium per liter infusing at 35 ml/hr. Which finding should be immediately reported to the healthcare provider?
- A. 3 episodes of vomiting in 1 hour.
- B. Periodic crying and irritability.
- C. Vigorous sucking on a pacifier.
- D. No measurable voiding in 4 hours.
Correct answer: No measurable voiding in 4 hours.
Rationale: The critical finding that should be reported immediately to the healthcare provider is 'No measurable voiding in 4 hours.' This finding raises concerns about possible hyperkalemia, which can result from continued potassium administration and a decrease in urinary output. Hyperkalemia can lead to serious complications, including cardiac arrhythmias. The management of acute hyperkalemia involves interventions such as administering calcium to protect the heart, shifting potassium into cells, and enhancing potassium elimination from the body. The other choices do not indicate an urgent issue that requires immediate attention. Three episodes of vomiting in 1 hour can be concerning but may not be as immediately critical as the risk of hyperkalemia. Periodic crying and irritability are common in infants and may not indicate a severe complication. Vigorous sucking on a pacifier is a normal behavior in infants and does not signal a medical emergency.
4. Which of the following conditions most commonly causes acute glomerulonephritis?
- A. A congenital condition leading to renal dysfunction.
- B. Prior infection with group A Streptococcus within the past 10-14 days.
- C. Viral infection of the glomeruli.
- D. Nephrotic syndrome.
Correct answer: Prior infection with group A Streptococcus within the past 10-14 days.
Rationale: Acute glomerulonephritis is most commonly caused by the immune response to a prior upper respiratory infection with group A Streptococcus. Glomerular inflammation occurs about 10-14 days after the infection, resulting in scant, dark urine and retention of body fluid. Periorbital edema and hypertension are common signs at diagnosis.
5. A patient is undergoing a stress test on a treadmill and turns to talk to the nurse. Which of these statements would require the most immediate intervention?
- A. I'm feeling extremely thirsty and will get some water after this.
- B. I can feel my heart racing.
- C. My shoulder and arm are hurting.
- D. My blood pressure reading is 158/80
Correct answer: C: My shoulder and arm are hurting.
Rationale: The correct answer is 'C: My shoulder and arm are hurting.' Unilateral arm and shoulder pain are classic symptoms of myocardial ischemia, indicating possible heart issues. In this scenario, immediate intervention is required, and the stress test should be halted. Choice A about feeling thirsty does not indicate an acute medical issue. Choice B mentioning heart racing is expected during a stress test. Choice D, a blood pressure reading of 158/80, while slightly elevated, does not present an immediate concern compared to the symptoms of arm and shoulder pain suggesting cardiac distress.
