NCLEX RN Exam Review Answers
1. The infant has a diagnosis of bladder exstrophy. To protect the exposed bladder tissue, what intervention should the nurse plan?
- A. Cover the bladder with petroleum jelly gauze.
- B. Cover the bladder with a non-adhering plastic wrap.
- C. Apply sterile distilled water dressings over the bladder mucosa.
- D. Keep the bladder tissue dry by covering it with dry sterile gauze.
Correct answer: C
Rationale: Bladder exstrophy is a condition where the bladder is exposed and external to the body. To protect the exposed bladder tissue from drying out while allowing urine drainage, it is best to cover the bladder with a non-adhering plastic wrap. Using petroleum jelly gauze should be avoided as it can dry out, adhere to the mucosa, and damage delicate tissue upon removal. Applying sterile distilled water dressings can also dry out and cause damage when removed. Keeping the bladder tissue dry with sterile gauze is not ideal as maintaining a moist environment is important for tissue protection in this case.
2. A patient in metabolic alkalosis is admitted to the emergency department, and pulse oximetry indicates that the O2 saturation is 94%. Which action should the nurse take next?
- A. Administer bicarbonate.
- B. Complete a head-to-toe assessment.
- C. Place the patient on high-flow oxygen.
- D. Obtain repeat arterial blood gases (ABGs).
Correct answer: C
Rationale: In a patient with metabolic alkalosis and an O2 saturation of 94%, placing the patient on high-flow oxygen is the correct action. Even though the O2 saturation seems adequate, metabolic alkalosis causes a left shift in the oxyhemoglobin dissociation curve, reducing oxygen delivery to tissues. Therefore, providing high-flow oxygen can help compensate for this. Administering bicarbonate would exacerbate the alkalosis. While completing a head-to-toe assessment and obtaining repeat ABGs are important interventions, the priority in this scenario is to improve oxygen delivery by placing the patient on high-flow oxygen.
3. What drives respiration in a patient with advanced chronic respiratory failure?
- A. Hypoxemia
- B. Hypocapnia
- C. Hypercapnia
- D. None of the above
Correct answer: A
Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.
4. Which food should the assistive personnel be instructed to remove from the child's food tray based on the prescribed treatment for nephrotic syndrome?
- A. Pickle
- B. Wheat toast
- C. Baked chicken
- D. Steamed vegetables
Correct answer: A
Rationale: In nephrotic syndrome, a no-added-salt diet is recommended to manage the condition. High-sodium foods like pickles should be avoided as they can exacerbate fluid retention and swelling. Wheat toast, baked chicken, and steamed vegetables are generally suitable for individuals with nephrotic syndrome as they are low in sodium and protein, which are important considerations for this condition. Therefore, the correct choice is to remove the pickles from the child's food tray.
5. The nurse is caring for a 13-year-old following spinal fusion for scoliosis. Which of the following interventions is appropriate in the immediate post-operative period?
- A. Raise the head of the bed at least 30 degrees
- B. Encourage ambulation within 24 hours
- C. Maintain in a flat position, logrolling as needed
- D. Encourage leg contraction and relaxation after 48 hours
Correct answer: C
Rationale: In the immediate post-operative period following spinal fusion for scoliosis in a 13-year-old, it is important to maintain the patient in a flat position and perform logrolling as needed. This helps prevent injury to the surgical site and ensures proper spinal alignment. Raising the head of the bed at least 30 degrees is contraindicated as it can put strain on the surgical site. Encouraging ambulation within 24 hours may be appropriate in the recovery process but not in the immediate post-operative period. Encouraging leg contraction and relaxation after 48 hours may also be part of the rehabilitation process but is not a priority in the immediate post-operative period.
