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. The family of a patient who is receiving therapeutic hypothermia states they do not understand why the patient is being kept so cold. What objective information can you provide to help address their concerns?

• A. Let them talk to another patient who has had the same therapy
• B. Provide research-based information about therapeutic hypothermia
• C. Connect them with the nurse manager
• D. Call the physician and ask him to talk to the family

Correct answer: B

Rationale: Providing research-based information about the benefits of therapeutic hypothermia for their loved one will provide evidence that this is an established therapy with generally positive outcomes. Families are certainly not expected to be familiar with critical care interventions, and their concerns should be addressed with evidence-based data whenever possible. Option A is not appropriate as sharing patient information violates privacy laws and does not address the family's concerns directly. Option C may not directly provide the detailed information the family needs to understand therapeutic hypothermia. Option D involves unnecessary escalation by immediately involving the physician, when providing education and information should be the initial step in addressing the family's concerns.

3. Mrs. F has been diagnosed with hyperparathyroidism. Which of the following complications is Mrs. F at highest risk of developing?

• A. Hyponatremia
• B. Hypocalcemia
• C. Hypermagnesemia
• D. Hypercalcemia

Correct answer: D

Rationale: The parathyroid glands regulate calcium, vitamin D, and phosphorus in the body. Hyperparathyroidism leads to excessive production of parathyroid hormone, causing the release of calcium from bones into the bloodstream, resulting in elevated blood calcium levels, known as hypercalcemia. This puts individuals at risk of developing complications such as kidney stones, bone pain, osteoporosis, and neuropsychiatric symptoms. The other options, hyponatremia, hypocalcemia, and hypermagnesemia, are not directly associated with hyperparathyroidism. Hyponatremia is low sodium levels in the blood, hypocalcemia is low calcium levels, and hypermagnesemia is high magnesium levels, which are not typically seen in hyperparathyroidism.

4. Which example best describes the concept of beneficence?

• A. A nurse provides pain medication for a client in the recovery room who is experiencing pain
• B. A client has an advanced directive in place stating that he does not want intubation if he needs CPR
• C. At the request of the client, a nurse does not inform the family about his cancer diagnosis
• D. A nurse withholds narcotic medication for a client in pain, knowing that he is currently disoriented

Correct answer: A

Rationale: Beneficence is the ethical principle of doing good and acting in the best interest of the client. Providing pain relief to a client in the recovery room who is experiencing pain aligns with beneficence as it promotes the client's well-being and comfort. Choice B is related to autonomy, where the client's wishes regarding treatment are respected. Choice C involves confidentiality and the client's right to privacy. Choice D represents nonmaleficence, as withholding pain medication from a client in pain could cause harm and goes against the principle of doing no harm.

5. If a healthcare professional prevents intentional harm from occurring to a patient, which ethical principle is being supported?

• A. Beneficence
• B. Nonmaleficence
• C. Justice
• D. Fidelity

Correct answer: B

Rationale: The correct answer is Nonmaleficence. Nonmaleficence is the ethical principle that emphasizes the obligation to avoid causing harm intentionally. In this scenario, by preventing intentional harm to a patient, the healthcare professional is upholding the principle of nonmaleficence. Beneficence, although important, focuses on doing good and promoting well-being rather than solely preventing harm. Justice relates to fairness and equality in resource distribution, while fidelity involves being faithful and keeping promises, which are not directly applicable to the situation of preventing intentional harm to a patient.
