NCLEX RN Exam Review Answers
1. The nurse is assessing a 3-year-old child for symptoms of autism spectrum disorder (ASD). Which assessment finding should lead the nurse to question the diagnosis?
- A. Inability to react appropriately to social cues
- B. Engages in repetitive behaviors
- C. Comprehends language well beyond the complexity expected for age
- D. Displays self-destructive behavior
Correct answer: C
Rationale: The correct answer is 'Comprehends language well beyond the complexity expected for age.' Children with autism spectrum disorder typically struggle with language and communication skills, so comprehending language well beyond their age level would not align with the diagnosis of ASD. This finding could indicate other developmental strengths or delays. Choices A, B, and D are more commonly associated with ASD - the inability to react appropriately to social cues, engaging in repetitive behaviors, and displaying self-destructive behavior are typical manifestations of autism spectrum disorder.
2. A child has recently been diagnosed with Duchenne muscular dystrophy (DMD). The parents are receiving genetic counseling prior to planning another pregnancy. Which of the following statements includes the most accurate information?
- A. Duchenne is an X-linked recessive disorder, so daughters have a 50% chance of being carriers and sons a 50% chance of developing the disease.
- B. Duchenne is an X-linked recessive disorder, so both daughters and sons have a 50% chance of developing the disease.
- C. Each child has a 1 in 4 (25%) chance of developing the disorder.
- D. Sons only have a 1 in 4 (25%) chance of developing the disorder.
Correct answer: A
Rationale: The correct answer is that Duchenne is an X-linked recessive disorder, meaning the affected gene is located on one of the two X chromosomes of a female carrier. If a son receives the X chromosome bearing the gene, he will develop the disease, giving him a 50% chance of being affected. Daughters, on the other hand, are not affected by Duchenne but have a 50% chance of being carriers since they inherit one copy of the defective gene from the mother. The other X chromosome is inherited from the father, who cannot be a carrier. Therefore, choice A is accurate. Choice B is incorrect because daughters do not develop the disease, and sons have a 50% chance of developing, not both having a 50% chance. Choice C is incorrect as it does not consider the X-linked inheritance pattern of Duchenne. Choice D is inaccurate as it incorrectly states that only sons have a 25% chance of developing the disorder, omitting the carrier status of daughters.
3. Which of these statements best describes the characteristics of an effective reward feedback system?
- A. Specific feedback is given as close to the event as possible
- B. Staff is given feedback in equal amounts over time
- C. Positive statements precede negative statements
- D. Performance goals should be higher than what is attainable
Correct answer: A
Rationale: The correct answer is that specific feedback should be given as close to the event as possible in an effective reward feedback system. This is important because feedback is most useful when provided immediately. Giving feedback promptly reinforces positive behavior and helps in modifying problem behaviors. Providing feedback close to the event helps in ensuring that standards are clearly understood and can be met. Choices B, C, and D are incorrect because staff should not be given feedback in equal amounts over time, positive statements do not necessarily have to precede negative statements, and setting performance goals higher than what is attainable can lead to demotivation and decreased performance.
4. An occupational health nurse works at a manufacturing plant where there is potential exposure to inhaled dust. Which action, if recommended by the nurse, will be most helpful in reducing the incidence of lung disease?
- A. Treat workers with pulmonary fibrosis.
- B. Teach about symptoms of lung disease.
- C. Require the use of protective equipment.
- D. Monitor workers for coughing and wheezing.
Correct answer: C
Rationale: Prevention of lung disease requires the use of appropriate protective equipment such as masks to reduce exposure to inhaled dust, which is a significant risk factor for lung disease. Teaching about symptoms of lung disease, treating workers with pulmonary fibrosis, and monitoring for coughing and wheezing are important actions for early recognition and treatment of lung disease. However, the most effective strategy to prevent lung damage in this scenario is to require the use of protective equipment to minimize exposure to harmful substances.
5. Which of the following types of antipsychotic medications is most likely to produce extrapyramidal effects?
- A. Atypical antipsychotic drugs
- B. First-generation antipsychotic drugs
- C. Third-generation antipsychotic drugs
- D. Dopamine system stabilizers
Correct answer: B
Rationale: The correct answer is first-generation antipsychotic drugs. These drugs are potent antagonists of D2, D3, and D4 receptors, making them effective in treating target symptoms but also leading to numerous extrapyramidal side effects due to the blockade of D2 receptors. Atypical or second-generation antipsychotic drugs, as mentioned in choice A, are relatively weak D2 blockers, which results in a lower incidence of extrapyramidal side effects. Third-generation antipsychotic drugs, as in choice C, and dopamine system stabilizers, as in choice D, are not typically associated with significant extrapyramidal effects compared to first-generation antipsychotics.
