NCLEX RN Practice Questions With Rationale
1. Who among the following individuals wrote a medical code of ethics?
- A. Hammurabi
- B. Thomas Percival
- C. Hippocrates
- D. All of the above
Correct answer: D
Rationale: All of the above individuals contributed to the development of medical ethics. Hammurabi created the earliest known code around 2500 BC. Hippocrates, known for the principle 'Do no harm,' emphasized ethical practices in medicine. Thomas Percival, a physician interested in sociological medicine, authored a Code of Medical Ethics in 1803, which influenced modern medical ethics. Therefore, the correct answer is 'All of the above.' Choices A, B, and C are incorrect because each of them individually wrote a medical code of ethics, making 'All of the above' the most inclusive and accurate answer.
2. The key to the prevention of a pandemic influenza is:
- A. Early detection
- B. Early antibiotic treatment
- C. Vaccination of at-risk populations
- D. Isolation of suspected cases
Correct answer: A
Rationale: The key to preventing a pandemic influenza is early detection. Detecting influenza cases early allows for timely public health responses to limit the spread of the virus. Early detection helps in implementing measures such as isolation, treatment, and vaccination to prevent the development of a full-blown pandemic. Antibiotics are not effective against influenza viruses, so early antibiotic treatment is not the key to prevention. While vaccination of at-risk populations is important in controlling the spread of influenza, early detection is crucial as it allows for timely implementation of vaccination strategies. Isolation of suspected cases is a containment measure rather than a prevention strategy; the key to prevention lies in early detection to stop the spread before it becomes a pandemic.
3. The healthcare professional needs to validate which of the following statements pertaining to an assigned client?
- A. The client has a hard, raised, red lesion on his right hand.
- B. A weight of 185 lbs. is recorded in the chart.
- C. The client reported an infected toe.
- D. The client's blood pressure is 124/70.
Correct answer: C
Rationale: Validation is the process of confirming that data are actual and factual. Data that can be measured can be accepted as factual, as in options 1, 3, and 4. The weight, blood pressure, and physical appearance of a lesion can be objectively verified. However, option C, the client reporting an infected toe, requires the nurse to directly assess the client's toe to confirm the statement. This choice involves subjective data that needs to be validated through direct observation, making it the correct answer. Options A, B, and D provide data that can be measured objectively and verified without the need for further assessment.
4. 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.
5. Which of the following statements best describes compartment syndrome?
- A. An injury causes pain and tingling that starts in the buttock and travels down the leg.
- B. An injury causes swelling within muscle tissue that leads to anoxia of nerves and muscles.
- C. An injury causes permanent flexion of the interphalangeal joint, resulting in deformity.
- D. An injury causes pain and swelling of the median plantar nerve.
Correct answer: B
Rationale: Compartment syndrome is characterized by swelling and increased pressure within a muscle compartment, leading to decreased blood flow and oxygen supply to nerves and muscles. This can result from various causes, such as trauma or the application of a cast after a fracture. If left untreated, compartment syndrome can lead to tissue necrosis. Choice A is incorrect as pain and tingling starting in the buttock and traveling down the leg are not specific features of compartment syndrome. Choice C is incorrect as permanent flexion of the interphalangeal joint is unrelated to compartment syndrome. Choice D is incorrect as pain and swelling of the median plantar nerve do not describe compartment syndrome.
