Nursing Elites

1. 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.

2. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?

• A. External light sources may cause falsely high oximetry values
• B. A bright light in the client's face may cause a low pulse oximetry
• C. External light sources may cause falsely low oximetry values
• D. The client needs a dark and quiet room to recover and maintain proper oxygenation

Correct answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.

3. A client diagnosed with schizophrenia is slow to respond and appears to be listening to unseen others. Which medication should a nurse expect a physician to order to address this type of symptom?

• A. Haloperidol (Haldol) to address the negative symptom
• B. Clonazepam (Klonopin) to address the positive symptom
• C. Risperidone (Risperdal) to address the positive symptom
• D. Clozapine (Clozaril) to address the negative symptom

Correct answer: C

Rationale: The correct medication to address the symptom described, where the client is slow to respond and appears to be listening to unseen others, is Risperidone (Risperdal). Risperidone is an atypical antipsychotic that is commonly used to manage positive symptoms of schizophrenia. Positive symptoms can include hallucinations, delusions, and disorganized thinking. Haloperidol (Haldol) and Clozapine (Clozaril) are typically used for addressing negative symptoms, such as lack of motivation or social withdrawal. Clonazepam (Klonopin) is a benzodiazepine primarily used for anxiety disorders and seizures, not for addressing symptoms of schizophrenia.

4. 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.

5. When teaching a Vietnamese patient who has been treated for pneumonia and needs to complete her antibiotic regimen at home, what is an important cultural component to consider?

• A. Cupping will help to pull toxins from the body
• B. Coining will help to release the wind or bad energy from the body
• C. Once symptoms disappear there is no longer an illness
• D. Most households consist of at least 3 generations

Correct answer: C

Rationale: The correct answer is 'Once symptoms disappear there is no longer an illness'. In Vietnamese culture, there is a belief that once symptoms go away, the illness is no longer present and does not require further treatment. This is crucial to understand when educating Vietnamese patients about completing their antibiotic regimen. Choices A and B (cupping and coining) are traditional Vietnamese healing practices that are not directly related to completing antibiotic therapy. Choice D, about households consisting of multiple generations, is not directly relevant to the completion of antibiotic treatment for pneumonia in this context.
