NCLEX RN Practice Questions With Rationale
1. After a lengthy explanation of a medical procedure, the patient asks many questions. The physician answers all of the questions to the best of their ability. The patient then gives consent for treatment. The costly equipment and supplies are put into place, and the patient is prepared. Two minutes before the procedure is to start, the patient begins panicking and changes their mind. Which of the following situations would be the best way to avoid litigation?
- A. Document that the patient originally gave consent and proceed if the benefits of the procedure outweigh the patient's wishes.
- B. Have the patient sign a form stating that they are refusing consent. If they refuse to sign, do not proceed with the procedure.
- C. Repeat the explanation of the procedure until the patient understands that having the procedure done is the best form of treatment. Do not proceed with the procedure.
- D. Do not proceed. Document the patient's refusal, have the patient sign a refusal to consent to treatment. If the patient refuses to sign the form, have a witness available to sign.
Correct answer: D
Rationale: In this scenario, the best course of action to avoid litigation is to respect the patient's right to refuse treatment, especially when changing their mind before the procedure starts. By not proceeding with the treatment, documenting the patient's refusal, and having the patient sign a refusal to consent form, you are following proper ethical and legal procedures. If the patient refuses to sign the form, having a witness available to sign further strengthens the documentation of the patient's decision. This approach ensures that the patient's autonomy and right to make informed decisions about their healthcare are respected. Choices A, B, and C do not prioritize the patient's right to refuse treatment and could potentially lead to legal issues if treatment is carried out against the patient's wishes.
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. Mrs. G is seen for follow-up after testing for chronically high blood glucose levels. Her physician diagnoses her with type 1 diabetes. Which of the following information is part of this client's education about this condition?
- A. Type 1 diabetes occurs due to increased carbohydrate intake and lack of exercise
- B. Type 1 diabetes is managed through diet and exercise
- C. Type 1 diabetes is caused by destruction of beta cells in the pancreas
- D. Type 1 diabetes leads to the body's cells rejecting insulin
Correct answer: C
Rationale: Type 1 diabetes is an autoimmune condition where the immune system attacks and destroys the beta cells in the pancreas, leading to a lack of insulin production. Insulin is essential for regulating blood glucose levels and enabling cells to use glucose for energy. Understanding that type 1 diabetes results from the destruction of beta cells helps patients comprehend the need for insulin replacement therapy. Choices A and B are incorrect as type 1 diabetes is not primarily caused by diet or exercise habits. Choice D is incorrect because type 1 diabetes is not about the body's cells rejecting insulin but rather the lack of insulin production due to beta cell destruction.
4. A nurse is providing dismissal instructions for a child who was admitted for rotavirus. Which of the following statements by the parent indicates the need for further teaching?
- A. I'll start giving him his antibiotics as soon as we get home.
- B. I will call the physician if he becomes dizzy or overly fussy.
- C. He will need to wash his hands a lot to keep this from spreading.
- D. I'll watch to see when he stops having diarrhea stools.
Correct answer: A
Rationale: The correct answer is 'I'll start giving him his antibiotics as soon as we get home.' Rotavirus is a viral illness, and antibiotics are ineffective for its treatment. The parent's statement indicates a need for further teaching as antibiotics are not appropriate for treating rotavirus. Option B is correct as it demonstrates the parent's understanding of when to contact the physician for concerning symptoms. Option C is a correct statement regarding infection control practices. Option D is also correct as monitoring diarrhea stools is essential to track recovery from rotavirus.
5. Which of the following interventions is necessary before insertion of an arterial line into the radial artery?
- A. Ensure that the client does not need surgery
- B. Assess the client's grip strength
- C. Perform an Allen test
- D. Check a serum potassium level
Correct answer: C
Rationale: Before inserting an arterial line into the radial artery, it is crucial to perform an Allen test. The Allen test assesses the collateral circulation to the hand by compressing both the radial and ulnar arteries. By occluding the radial artery and releasing the ulnar artery, the nurse can check if the ulnar artery can adequately supply blood to the hand if the radial artery is cannulated. This step ensures that there is adequate circulation to the hand post-insertion of the arterial line. Choice A, ensuring that the client does not need surgery, is not directly related to the insertion of an arterial line and is not a necessary step before the procedure. Choice B, assessing grip strength, is not specific to the vascular status of the hand and does not provide information about the adequacy of collateral circulation. Choice D, checking a serum potassium level, is unrelated to the assessment of radial artery patency and collateral circulation, which are the primary concerns before arterial line insertion.
