NCLEX RN Exam Review Answers
1. 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.
2. When assessing a child admitted to the hospital with pyloric stenosis, which symptom would the nurse likely find when asking the parent about the child's symptoms?
- A. Watery diarrhea
- B. Projectile vomiting
- C. Increased urine output
- D. Vomiting large amounts of bile
Correct answer: B
Rationale: In pyloric stenosis, hypertrophy of the circular muscles of the pylorus causes narrowing of the pyloric canal between the stomach and the duodenum. The hallmark symptom of pyloric stenosis is projectile vomiting, which is the forceful expulsion of stomach contents. Other common symptoms include irritability, hunger and crying, constipation, and signs of dehydration. Watery diarrhea (Choice A) is not a typical symptom of pyloric stenosis. Increased urine output (Choice C) is not directly associated with this condition. Vomiting large amounts of bile (Choice D) is not a characteristic symptom of pyloric stenosis; instead, the vomitus in pyloric stenosis is non-bilious.
3. A two-year-old child has sustained an injury to the leg and refuses to walk. The nurse in the emergency department documents swelling of the lower affected leg. Which of the following does the nurse suspect is the cause of the child's symptoms?
- A. Possible fracture of the tibia.
- B. Bruising of the gastrocnemius muscle.
- C. Possible fracture of the radius.
- D. No anatomic injury, the child wants his mother to carry him.
Correct answer: A
Rationale: The child's refusal to walk, along with swelling of the lower leg, indicates a possible fracture, specifically of the tibia. Fractures can cause pain and swelling, leading to difficulty or refusal to bear weight on the affected limb. Choice B, bruising of the gastrocnemius muscle, would not typically result in the child refusing to walk. Choice C, a possible fracture of the radius, is less likely given the location of the swelling and the associated refusal to walk. Choice D, stating no anatomic injury and attributing the child's behavior to wanting to be carried by the mother, is incorrect as the physical findings suggest a potential fracture that needs to be evaluated further.
4. A 23-year-old has been admitted with acute liver failure. Which assessment data are most important for the nurse to communicate to the healthcare provider?
- A. Asterixis and lethargy
- B. Jaundiced sclera and skin
- C. Elevated total bilirubin level
- D. Liver 3 cm below costal margin
Correct answer: A
Rationale: The most critical assessment data for the nurse to communicate to the healthcare provider in a patient with acute liver failure are asterixis and lethargy. These findings are indicative of grade 2 hepatic encephalopathy, which signals a rapid deterioration in the patient's condition, necessitating early transfer to a transplant center. Jaundiced sclera and skin, elevated total bilirubin level, and a liver 3 cm below the costal margin are all typical findings in hepatic failure but do not indicate an immediate need for a change in the therapeutic plan. Therefore, while these findings are relevant and should be reported, they are not as urgent as asterixis and lethargy in a patient with acute liver failure.
5. The nurse is caring for a post-surgical client at risk for developing deep vein thrombosis. Which intervention is an effective preventive measure?
- A. Use elastic stockings continuously
- B. Encourage range of motion and ambulation
- C. Massage the legs twice daily
- D. Place pillows under the knees
Correct answer: B
Rationale: Encouraging range of motion and ambulation is an effective preventive measure for deep vein thrombosis in post-surgical clients. Mobility helps improve blood circulation, reducing the risk of clot formation. Elastic stockings help prevent blood pooling and clotting in the legs by providing external pressure to support venous return. Massaging the legs twice daily may help with circulation but is not as effective as promoting movement and ambulation. Placing pillows under the knees is a comfort measure and does not directly address the prevention of deep vein thrombosis.
