NCLEX RN Exam Review Answers
1. A patient with Meningitis is being treated with Vancomycin intravenously 3 times per day. The nurse notes that the urine output during the last 8 hours was 200mL. What is the nurse's priority action?
- A. Check the patient's last BUN levels
- B. Ask the patient to increase their fluid intake
- C. Ask the physician to order a diuretic
- D. Notify the physician of this finding
Correct answer: D
Rationale: Vancomycin is a nephrotoxic drug and can cause impaired renal perfusion, which would lead to decreased urine output. This is a serious adverse effect that should be promptly reported to the physician. Checking the patient's last BUN levels (Choice A) may provide additional information but does not address the urgency of the situation. Asking the patient to increase fluid intake (Choice B) may not be appropriate if the cause is related to Vancomycin toxicity. Ordering a diuretic (Choice C) without physician evaluation can exacerbate the issue, making notifying the physician (Choice D) the most critical action to take.
2. 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.
3. The nurse palpates the posterior chest while the patient says 99 and notes absent fremitus. What action should the nurse take next?
- A. Auscultate anterior and posterior breath sounds bilaterally
- B. Encourage the patient to turn, cough, and deep breathe
- C. Review the chest x-ray report for evidence of pneumonia
- D. Palpate the anterior chest and observe for barrel chest
Correct answer: A
Rationale: To assess for tactile fremitus, the nurse should use the palms of the hands to assess for vibration when the patient repeats a word or phrase such as '99'. After noting absent fremitus, the nurse should then auscultate the lungs to assess for the presence or absence of breath sounds. Absent fremitus may be noted with conditions like pneumothorax or atelectasis. The vibration is increased in conditions such as pneumonia, lung tumors, thick bronchial secretions, and pleural effusion. Encouraging the patient to turn, cough, and deep breathe is an appropriate intervention for atelectasis, but assessing breath sounds takes priority. Fremitus is decreased if the hand is farther from the lung or the lung is hyperinflated (barrel chest). Palpating the anterior chest for fremitus is less effective due to the presence of large muscles and breast tissue, making auscultation a more appropriate next step.
4. A patient with a history of diabetes mellitus is on the second postoperative day following cholecystectomy. She has complained of nausea and isn't able to eat solid foods. The nurse enters the room to find the patient confused and shaky. Which of the following is the most likely explanation for the patient's symptoms?
- A. Anesthesia reaction
- B. Hyperglycemia
- C. Hypoglycemia
- D. Diabetic ketoacidosis
Correct answer: C
Rationale: In a postoperative diabetic patient who is unable to eat solid foods, the likely cause of symptoms such as confusion and shakiness is hypoglycemia. Confusion and shakiness are common manifestations of hypoglycemia. Insufficient glucose supply to the brain (neuroglycopenia) can lead to confusion, difficulty with concentration, irritability, hallucinations, focal impairments like hemiplegia, and, in severe cases, coma and death. Anesthesia reaction (Choice A) is less likely in this scenario as the patient is already on the second postoperative day. Hyperglycemia (Choice B) is unlikely given the patient's symptoms and history of not eating. Diabetic ketoacidosis (Choice D) typically presents with hyperglycemia, ketosis, and metabolic acidosis, which are not consistent with the patient's current symptoms of confusion and shakiness.
5. 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: B
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.
