NCLEX RN Exam Questions

1. Which goal has the highest priority in the plan of care for a 26-year-old homeless patient admitted with viral hepatitis who has severe anorexia and fatigue?

A. Increase activity level.
B. Maintain adequate nutrition
C. Establish a stable environment
D. Identify sources of hepatitis exposure

Correct answer: B

Rationale: The highest priority outcome is to maintain adequate nutrition because it is essential for hepatocyte regeneration. In viral hepatitis, the liver is affected, and proper nutrition supports the liver's function and regeneration. While increasing activity level and establishing a stable environment are important, they are not as urgent as ensuring the patient receives proper nutrition. Identifying sources of hepatitis exposure can help prevent future infections, but in the acute phase, the immediate focus should be on providing adequate nutrition to support the patient's recovery.

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. Why should a 30-year-old Caucasian woman who works the night shift take Vitamin D supplements?

A. It's a standard part of the overall nutritional treatment for the prevention of osteomalacia.
B. It helps your intestines absorb calcium, which is important for bone formation.
C. It stimulates skin cells to produce calcium, which is then released into the bloodstream to be used for bone formation.
D. Vitamin D supplements should not be taken by someone of your age.

Correct answer: B

Rationale: The correct answer is B: 'It helps your intestines absorb calcium, which is important for bone formation.' Vitamin D plays a crucial role in aiding the absorption of calcium from the intestines into the bloodstream, which is essential for bone health and formation. Choice A is incorrect because it does not specifically address the role of Vitamin D in calcium absorption. Choice C is incorrect as Vitamin D does not stimulate skin cells to produce calcium; rather, it helps regulate calcium levels in the body. Choice D is incorrect as age alone is not a contraindication for Vitamin D supplementation; the need for supplementation is based on individual health status and risk factors.

4. How does shock typically progress?

A. Compensated to hypotensive shock in hours and hypotensive shock to cardiac arrest in minutes
B. Compensated to hypotensive shock in minutes and hypotensive shock to cardiac arrest in hours
C. Hypotensive to compensated shock in hours and compensated shock to cardiac arrest in minutes
D. Hypotensive to compensated shock in minutes and compensated shock to cardiac arrest in hours

Correct answer: A

Rationale: Shock typically progresses from a compensated state to hypotensive shock over a period of hours. In the compensated phase, the body is trying to maintain perfusion. It is crucial to identify and intervene during this phase to prevent progression to hypotensive shock, where blood pressure drops significantly. If not promptly managed, hypotensive shock can rapidly deteriorate into cardiac arrest in minutes due to inadequate perfusion to vital organs. Choices B, C, and D are incorrect as they do not follow the typical progression of shock stages as seen in clinical practice. Understanding the stages of shock and their timeframes is crucial for early recognition and appropriate intervention to prevent further deterioration.

5. A patient asks a nurse administering blood how long red blood cells live in the body. What is the correct response?

A. The life span of RBC is 45 days
B. The life span of RBC is 60 days
C. The life span of RBC is 90 days
D. The life span of RBC is 120 days

Correct answer: D

Rationale: The correct answer is that red blood cells have a lifespan of 120 days in the body. This allows for efficient oxygen transport throughout the circulatory system. Choices A, B, and C are incorrect because the lifespan of red blood cells is actually 120 days. Understanding the lifespan of red blood cells is crucial in assessing various conditions related to blood cell production and turnover.
