NCLEX RN Exam Review Answers
1. The nurse is reviewing the lab results of a patient taking lithium for schizoaffective disorder. The lab results show that the blood lithium value is 1.7 mcg/L. What would the nurse take as the priority action?
- A. Induce vomiting
- B. Hold the next dose of Lithium
- C. Administer an antiemetic
- D. Give the next dose of Lithium
Correct answer: B
Rationale: The correct answer is to hold the next dose of Lithium. The blood lithium value of 1.7 mcg/L exceeds the therapeutic range of 0.5-1.5 mcg/L, indicating potential toxicity. Holding the next dose is crucial to prevent further accumulation of lithium in the bloodstream. Inducing vomiting is not appropriate in this situation as the priority is to prevent further absorption of lithium. Administering an antiemetic is not the priority in lithium toxicity. Giving the next dose of lithium would exacerbate the toxicity and should be avoided.
2. The patient with idiopathic pulmonary arterial hypertension (IPAH) is receiving epoprostenol (Flolan). Which assessment information requires the most immediate action by the nurse?
- A. The oxygen saturation is 94%.
- B. The blood pressure is 98/56 mm Hg.
- C. The patient's central IV line is disconnected.
- D. The international normalized ratio (INR) is prolonged.
Correct answer: C
Rationale: The most immediate action required by the nurse is to address the disconnected central IV line delivering epoprostenol (Flolan). Epoprostenol has a short half-life of 6 minutes, necessitating immediate reconnection to prevent rapid clinical deterioration. While oxygen saturation, blood pressure, and INR are important parameters requiring monitoring and intervention, the priority lies in ensuring the continuous delivery of the critical medication to stabilize the patient's condition.
3. 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: A
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.
4. The parents of a child with a hernia are instructed by the nurse on measures to reduce the hernia. Which statement indicates the parents understand the care for their child?
- A. We will encourage our child to cough every few hours on a daily basis.
- B. We will make sure that our child participates in physical activity every day.
- C. We will provide comfort measures to reduce any crying periods by our child.
- D. We will be sure to give our child a Fleet enema every day to prevent constipation.
Correct answer: C
Rationale: The correct answer is providing comfort measures to reduce any crying periods by the child. This can include offering a warm bath, avoiding upright positioning, and using other comfort measures to reduce crying, which can help reduce a hernia. Encouraging coughing or physical activity can increase strain on the hernia. Giving a Fleet enema daily for constipation is not recommended as it can also increase strain on the hernia.
5. A patient with a pleural effusion is scheduled for a thoracentesis. Which action should the nurse take to prepare the patient for the procedure?
- A. Start a peripheral IV line to administer any necessary sedative drugs.
- B. Position the patient sitting upright on the edge of the bed and leaning forward.
- C. Obtain a collection device to hold a reasonable amount of pleural fluid for extraction.
- D. Remove the water pitcher and remind the patient not to eat or drink anything for 6 hours.
Correct answer: B
Rationale: The correct action for the nurse to take in preparing a patient for a thoracentesis is to position the patient sitting upright on the edge of the bed and leaning forward. This position helps fluid accumulate at the lung bases, making it easier to locate and remove. Sedation is not usually required for a thoracentesis, so starting an IV line for sedative drugs is unnecessary. Additionally, there are no restrictions on oral intake before the procedure since the patient is not sedated or unconscious. A large collection device to hold 2 to 3 liters of pleural fluid at one time is excessive as usually only 1000 to 1200 mL of pleural fluid is removed to avoid complications like hypotension, hypoxemia, or pulmonary edema. Therefore, the correct choice is to position the patient upright for the procedure.
