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. The nurse plans health care for a community with a large number of recent immigrants from Vietnam. Which intervention is the most important for the nurse to implement?
- A. Hepatitis testing
- B. Tuberculosis screening
- C. Contraceptive teaching
- D. Colonoscopy information
Correct answer: B
Rationale: Tuberculosis (TB) is prevalent in many parts of Asia, including Vietnam, and the incidence of TB is higher in immigrants from Vietnam compared to the general U.S. population. Conducting tuberculosis screening is crucial to identify and address any cases promptly, especially in a community with recent immigrants from Vietnam. While teaching about contraceptive use, providing colonoscopy information, and testing for hepatitis may be relevant for certain individuals in the community, they are not as universally important as tuberculosis screening due to the increased risk of TB among Vietnamese immigrants.
3. A client with asthma has low-pitched wheezes present in the final half of exhalation. One hour later, the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client:
- A. Has increased airway obstruction.
- B. Has improved airway obstruction.
- C. Needs to be suctioned.
- D. Exhibits hyperventilation.
Correct answer: B
Rationale: The change from low-pitched wheezes to high-pitched wheezes indicates a shift from larger to smaller airway obstruction, suggesting increased narrowing of the airways. This change signifies a progression or worsening of the airway obstruction. The absence of evidence of secretions does not support the need for suctioning. Hyperventilation is characterized by rapid and deep breathing, which is not indicated by the information provided in the question.
4. The nurse is teaching parents about the treatment plan for a 2-week-old infant with Tetralogy of Fallot. While awaiting future surgery, the nurse instructs the parents to immediately report
- A. Loss of consciousness
- B. Feeding problems
- C. Poor weight gain
- D. Fatigue with crying
Correct answer: A
Rationale: The correct answer is 'Loss of consciousness.' While parents should report any concerning observations, they need to call the healthcare provider immediately if the infant experiences a loss of consciousness. This change in alertness may indicate anoxia, which can be life-threatening. Tetralogy of Fallot is a congenital heart defect characterized by four main features: pulmonic stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy. Surgery for Tetralogy of Fallot may be delayed or done in stages. Reporting loss of consciousness is crucial due to the potential seriousness of the condition. Feeding problems, poor weight gain, and fatigue with crying are important issues but do not require immediate reporting like loss of consciousness does.
5. Why is it important to genotype HCV before initiating drug therapy?
- A. Side effects of nucleotide analogs
- B. Measures for improving the appetite
- C. Ways to increase activity and exercise
- D. Administering alpha-interferon (Intron A)
Correct answer: B
Rationale: Genotyping of HCV plays a crucial role in managing treatment as it helps determine the most effective therapy for the specific viral strain. It allows healthcare providers to personalize treatment regimens and predict response rates. The statement about acute HCV infection converting to chronic state is accurate, highlighting the need for appropriate management. Immune globulin and vaccines are not available for HCV, and Ribavirin is commonly used for chronic HCV infection. Improving appetite is essential in liver health as adequate nutritional intake supports hepatocyte regeneration. Choices A, C, and D are incorrect as they do not address the specific importance of genotyping in HCV treatment or the significance of appetite improvement in liver function.
