Exam Cram NCLEX RN Practice Questions
1. You are caring for Thomas N., a 77-year-old man with edema in his legs and a fluid restriction. You have been assigned to weigh him daily. Based on these symptoms and the care he is receiving, what disorder is he most likely affected by?
- A. Diabetes
- B. Dementia
- C. Congestive heart failure
- D. Contiguous heart disease
Correct answer: C
Rationale: Thomas N.'s symptoms of edema in his legs and fluid restriction point towards congestive heart failure (CHF) rather than dementia or diabetes. In CHF, patients often present with dependent edema in their legs due to excessive blood volume, leading to fluid intake restrictions and a low-salt diet. Daily weight monitoring is crucial in CHF to assess fluid retention or loss. Diabetes primarily affects blood sugar levels, dementia is a cognitive disorder, and 'Contiguous heart disease' is not a recognized medical term, making choices A, B, and D incorrect in this scenario.
2. While eating in the hospital cafeteria, a nurse notices a toddler at a nearby table choking on a piece of food and appearing slightly blue. What is the appropriate initial action to take?
- A. Begin mouth-to-mouth resuscitation
- B. Give the child water to help with swallowing
- C. Perform 5 abdominal thrusts
- D. Call for the emergency response team
Correct answer: C
Rationale: When a toddler is choking on a piece of food and appears blue, it indicates airway obstruction. The appropriate initial action should be to perform 5 abdominal thrusts. This technique can help dislodge the obstructing object and clear the airway. Initiating mouth-to-mouth resuscitation is not recommended as the first step in a choking emergency, especially in children. Giving water may not be effective and can worsen the situation by causing further blockage. Calling the emergency response team should be considered if the abdominal thrusts are unsuccessful in clearing the airway.
3. An 85-year-old male has been losing mobility and gaining weight over the last two months. The patient also has the heater running in his house 24 hours a day, even on warm days. Which of the following tests is most likely to be performed?
- A. CBC (complete blood count)
- B. ECG (electrocardiogram)
- C. Thyroid function tests
- D. CT scan
Correct answer: C
Rationale: The symptoms of weight gain and poor temperature tolerance in an elderly male suggest a potential thyroid dysfunction. Thyroid function tests are crucial in differentiating between hyperthyroidism, hypothyroidism, and a euthyroid state. These tests involve measuring the serum levels of thyroid hormones T3 and T4, also known as thyroxine, to evaluate thyroid function accurately. A complete blood count (Choice A) would not directly address the symptoms presented. An electrocardiogram (Choice B) assesses heart activity and would not be the primary test for these symptoms. A CT scan (Choice D) provides detailed images of internal organs and structures, which would not be the initial investigation for the described symptoms.
4. 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.
5. 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.
