Exam Cram NCLEX RN Practice Questions
1. An 80-year-old patient is admitted with dyspnea, dependent edema, rales, and distended neck veins. As the nurse monitors the patient, he becomes increasingly short of breath and begins to have cardiac dysrhythmias. The most critical intervention for this patient is to:
- A. Ensure his airway is open and unobstructed.
- B. Apply oxygen to maintain his oxygen saturation above 94%.
- C. Administer Dobutamine to increase cardiac output.
- D. Start an IV for monitoring fluid intake.
Correct answer: A
Rationale: In a patient presenting with dyspnea, dependent edema, rales, distended neck veins, and developing cardiac dysrhythmias, the priority intervention is to ensure the airway is open and unobstructed. Maintaining an open airway is crucial for adequate ventilation and oxygenation, especially in a patient showing signs of impending respiratory distress and cardiac compromise. While applying oxygen to maintain oxygen saturation is important, ensuring airway patency takes precedence as it directly impacts the patient's ability to breathe. Administering Dobutamine may be necessary to improve cardiac output; however, addressing the airway first is essential to prevent further respiratory distress and worsening dysrhythmias. Starting an IV for monitoring fluid intake is not the most critical intervention in this scenario compared to ensuring airway patency and oxygenation.
2. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?
- A. 60 microdrops/minute
- B. 20 microdrops/minute
- C. 30 microdrops/minute
- D. 40 microdrops/minute
Correct answer: A
Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.
3. Which of the following is TRUE about shock?
- A. A patient with severe shock does not always have an abnormally low blood pressure.
- B. Confusion and deteriorating mentation are indicative of hypotensive shock.
- C. Patients with compensated shock may not be able to maintain a normal blood pressure.
- D. A normal blood pressure does not imply that the patient is stable.
Correct answer: B
Rationale: Confusion and deteriorating mentation are indeed indicative of hypotensive shock. It is important to note that a patient with hypotensive shock will likely exhibit deteriorating mental status. Choice A is incorrect because a patient in severe shock may not always have an abnormally low blood pressure, making it an unreliable indicator of shock severity. Choice C is incorrect because patients with compensated shock may present with normal blood pressure but still have inadequate tissue perfusion. Choice D is incorrect because a normal blood pressure does not guarantee the patient's stability, especially in cases of shock where tissue perfusion may be compromised despite normal blood pressure readings.
4. A patient comes to the emergency department with abdominal pain. Work-up reveals the presence of a rapidly enlarging abdominal aortic aneurysm. Which of the following actions should the nurse expect?
- A. The patient will be admitted to the medicine unit for observation and medication.
- B. The patient will be admitted to the day surgery unit for sclerotherapy.
- C. The patient will be admitted to the surgical unit and resection will be scheduled.
- D. The patient will be discharged home to follow-up with his cardiologist in 24 hours.
Correct answer: C
Rationale: A rapidly enlarging abdominal aortic aneurysm is at significant risk of rupture, which can be life-threatening. The standard treatment for a rapidly enlarging abdominal aortic aneurysm is surgical intervention to prevent rupture. Therefore, the appropriate action for the nurse to expect is that the patient will be admitted to the surgical unit, and resection will be scheduled. Observation and medication (Choice A) are not sufficient for a rapidly enlarging aneurysm, and sclerotherapy (Choice B) is not typically used for aortic aneurysms. Discharging the patient home (Choice D) would be inappropriate and dangerous given the risk of rupture.
5. Which finding indicates to the nurse that a patient's transjugular intrahepatic portosystemic shunt (TIPS) placed 3 months ago has been effective?
- A. Increased serum albumin level
- B. Decreased indirect bilirubin level
- C. Improved alertness and orientation
- D. Fewer episodes of bleeding varices
Correct answer: D
Rationale: The correct answer is 'Fewer episodes of bleeding varices.' A transjugular intrahepatic portosystemic shunt (TIPS) is used to reduce pressure in the portal venous system, thus decreasing the risk of bleeding from esophageal varices. This outcome would indicate the effectiveness of the TIPS procedure. The other choices are incorrect because: Increased serum albumin level and decreased indirect bilirubin level are not direct indicators of TIPS effectiveness. Improved alertness and orientation could be influenced by various factors and may not directly correlate with the effectiveness of the TIPS procedure. Additionally, TIPS can actually increase the risk of hepatic encephalopathy, which contradicts the choice of improved alertness and orientation.
