NCLEX RN Exam Review Answers
1. 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.
2. A client has no pulse or respirations. After calling for help, what should the nurse's first action be?
- A. Start a peripheral IV
- B. Initiate high-quality chest compressions
- C. Establish an airway
- D. Obtain the crash cart
Correct answer: B
Rationale: In a situation where a client has no pulse or respirations, the initial action recommended by the American Heart Association is to start high-quality chest compressions. This action helps maintain blood flow to vital organs such as the brain until normal heart rhythm is restored. Starting CPR with chest compressions before checking the airway and providing rescue breaths is crucial to improve outcomes. While establishing an airway and obtaining a crash cart are important steps in resuscitation, initiating chest compressions takes precedence to ensure oxygenated blood circulation. Starting with chest compressions applies to adults, children, and infants but not newborns.
3. A nurse is caring for an infant who has recently been diagnosed with a congenital heart defect. Which of the following clinical signs would most likely be present?
- A. Slow pulse rate
- B. Weight gain
- C. Decreased systolic pressure
- D. Irregular WBC lab values
Correct answer: B
Rationale: Weight gain due to fluid accumulation is associated with heart failure and congenital heart defects. When the heart is unable to circulate blood normally, the kidneys receive less blood, leading to reduced fluid filtration into the urine. The excess fluid accumulates in various body parts such as the lungs, liver, eyes, and sometimes in the legs. Slow pulse rate (Choice A) is less likely as infants with heart failure typically present with tachycardia due to the body compensating for decreased cardiac output. Decreased systolic pressure (Choice C) is also less likely as heart failure typically leads to increased blood pressure as the body tries to maintain adequate perfusion. Irregular white blood cell (WBC) values (Choice D) are not directly associated with congenital heart defects unless there is an underlying infection or inflammatory process.
4. Which question should the nurse ask the parents of a child suspected of having glomerulonephritis?
- A. Did your child fall off a bike onto the handlebars?
- B. Has the child had persistent nausea and vomiting?
- C. Has the child been itching or had a rash anytime in the last week?
- D. Has the child had a sore throat or a throat infection in the last few weeks?
Correct answer: D
Rationale: Glomerulonephritis refers to a group of kidney disorders characterized by inflammatory injury in the glomerulus. Group A ?-hemolytic streptococcal infection is a common cause of glomerulonephritis. Children with glomerulonephritis often develop symptoms after a throat infection caused by streptococcal bacteria. Therefore, asking about a sore throat or throat infection in the last few weeks is crucial to assess the possible link to glomerulonephritis. Choices A, B, and C are not directly associated with the pathophysiology of glomerulonephritis. Asking about falling off a bike, nausea and vomiting, or itching and rash do not provide relevant information for assessing glomerulonephritis in this context.
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.
