NCLEX RN Exam Review Answers
1. A 4-year-old child with acute glomerulonephritis is admitted to the hospital. The nurse identifies which client problem in the plan of care as the priority?
- A. Infection related to hypertension
- B. Injury related to loss of blood in urine
- C. Excessive fluid volume related to decreased plasma filtration
- D. Retarded growth and development related to a chronic disease
Correct answer: C
Rationale: In acute glomerulonephritis, the child experiences excessive accumulation of water and retention of sodium, leading to circulatory congestion and edema. Excessive fluid volume is a primary concern due to the disease process. Hypertension and infection are not directly related to acute glomerulonephritis; therefore, they are not the priority client problems. While hematuria (blood in urine) may occur, it typically does not lead to significant injury that takes precedence over excessive fluid volume. Acute glomerulonephritis is an acute condition, not chronic; therefore, retarded growth and development related to a chronic disease is not the priority issue. With proper management, most children recover completely without long-term growth and development issues.
2. A 1-year-old child is diagnosed with intussusception, and the mother of the child asks the student nurse to describe the disorder. Which statement by the student nurse indicates correct understanding of this disorder?
- A. It is an acute bowel obstruction.
- B. It is a condition that causes an acute inflammatory process in the bowel.
- C. It is a condition in which a distal segment of the bowel prolapses into a proximal segment of the bowel.
- D. It is a condition in which a proximal segment of the bowel prolapses into a distal segment of the bowel.
Correct answer: D
Rationale: Intussusception is a condition in which a proximal segment of the bowel telescopes or prolapses into a distal segment of the bowel. This leads to bowel obstruction and potential ischemia. It is not an acute bowel obstruction, as the obstruction is caused by the telescoping of bowel segments rather than a blockage in the bowel lumen. Intussusception is not primarily an inflammatory process; instead, it is a mechanical issue involving bowel invagination. Choice A is incorrect as it does not accurately describe the pathophysiology of intussusception. Choice C is incorrect because it presents the opposite scenario of what happens in intussusception.
3. A patient asks the nurse why they must have a heparin injection. What is the nurse's best response?
- A. Heparin will dissolve clots that you have.
- B. Heparin will reduce the platelets that make your blood clot.
- C. Heparin will work better than warfarin.
- D. Heparin will prevent new clots from developing.
Correct answer: D
Rationale: The correct answer is D: 'Heparin will prevent new clots from developing.' Heparin is an anticoagulant medication that helps prevent the formation of new blood clots. It does not dissolve existing clots (choice A), reduce platelets (choice B), or necessarily work 'better' than warfarin (choice C) but rather functions differently. The primary action of heparin is to prevent the development of new clots, especially in conditions where clot formation is a concern.
4. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:
- A. It results when oxygen demand is greater than oxygen supply.
- B. It is characterized by pain that often occurs during rest.
- C. It is a result of tissue hypoxia.
- D. It is characterized by cramping and weakness.
Correct answer: D
Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.
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.
