NCLEX RN Exam Review Answers
1. The nurse is reviewing the record of a child diagnosed with nephrotic syndrome. The nurse should expect to note which finding documented in the child's record?
- A. Polyuria
- B. Weight gain
- C. Hypotension
- D. Grossly bloody urine
Correct answer: B
Rationale: In nephrotic syndrome, a key finding documented in the child's record is weight gain due to massive edema. While urine may appear dark, foamy, and frothy, grossly bloody urine is not expected as only microscopic hematuria is present. Additionally, urine output is decreased, and hypertension is likely to be present. Therefore, the correct answer is weight gain as it aligns with the characteristic presentation of nephrotic syndrome.
2. A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?
- A. Hemoglobin of 11 g/dl
- B. Platelet count of 150,000
- C. INR of 2.5
- D. Potassium of 2.7 mEq/L
Correct answer: D
Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.
3. A patient's chart indicates a history of hyperkalemia. Which of the following would you not expect to see with this patient if this condition were acute?
- A. Decreased HR
- B. Paresthesias
- C. Muscle weakness of the extremities
- D. Migraines
Correct answer: D
Rationale: The correct answer is 'Migraines.' Migraines are not a symptom typically associated with hyperkalemia. In acute hyperkalemia, one would not expect to see migraines. Symptoms of hyperkalemia often include muscle weakness, paresthesias, and cardiac manifestations such as bradycardia or even cardiac arrest. Therefore, choices A, B, and C are more commonly associated with acute hyperkalemia compared to migraines, making it the correct choice.
4. The laboratory has just called with the arterial blood gas (ABG) results on four patients. Which result is most important for the nurse to report immediately to the health care provider?
- A. pH 7.34, PaO2 82 mm Hg, PaCO2 40 mm Hg, and O2 sat 97%
- B. pH 7.35, PaO2 85 mm Hg, PaCO2 45 mm Hg, and O2 sat 95%
- C. pH 7.46, PaO2 90 mm Hg, PaCO2 32 mm Hg, and O2 sat 98%
- D. pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%
Correct answer: D
Rationale: The correct answer is D: pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%. These ABG results indicate uncompensated respiratory acidosis, a critical condition that requires immediate attention. In respiratory acidosis, there is an excess of carbon dioxide in the blood, leading to a decrease in pH. The other options present normal or near-normal ABG values, indicating adequate oxygenation and ventilation. Therefore, these values would not be as urgent to report compared to the patient with respiratory acidosis in option D.
5. A client is found unresponsive in his room by a nurse. The client is not breathing and does not have a pulse. After calling for help, what is the next action the nurse should take?
- A. Administer 2 ventilations
- B. Perform a head-tilt, chin lift to open the airway
- C. Begin chest compressions
- D. Perform a jaw thrust to open the airway
Correct answer: C
Rationale: After finding an unresponsive client who is not breathing and has no pulse, the nurse's immediate action should be to call for help and start chest compressions. Chest compressions should be initiated at a rate of at least 100 per minute and a depth of at least 2 inches. Choice A, administering ventilations, is not the initial step as compressions take priority. Choice B, performing a head-tilt, chin lift, is also not the first step; chest compressions are crucial before airway management. Choice D, performing a jaw thrust, is typically used in cases of suspected cervical spine injury and is not the immediate action in this scenario.
