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. Which of the following conditions may warrant a serum creatinine level?

• A. Rhabdomyolysis
• B. Digitalis toxicity
• C. Glomerulonephritis
• D. All answers are correct

Correct answer: D

Rationale: A serum creatinine level may be warranted in conditions that can affect renal function or cause muscle breakdown. Rhabdomyolysis, characterized by muscle injury and breakdown, can lead to elevated creatinine levels due to the release of creatinine from muscles. Digitalis toxicity can impair renal function, leading to a need for monitoring creatinine levels. Glomerulonephritis, an inflammatory condition affecting the kidney's filtering units, can also impact renal function and require assessment of creatinine levels. Therefore, all the provided conditions may warrant a serum creatinine level to assess renal function and muscle breakdown.

3. The client has a long leg cast. During discharge teaching about appropriate exercises for the affected extremity, the nurse should recommend:

• A. Isometric
• B. Range of motion
• C. Aerobic
• D. Isotonic

Correct answer: D

Rationale: The nurse should recommend isometric exercises for the muscles of the casted extremity. Isometric exercises involve contracting and relaxing muscles without moving the affected part. This type of exercise helps maintain muscle strength without moving the joint, which is important for clients with immobilized extremities. Range of motion exercises involve moving the joint through its full range of motion, which may not be suitable for a client with a long leg cast. Aerobic exercises focus on increasing cardiovascular endurance and may not be appropriate for a client with a casted extremity. Isotonic exercises involve muscle contractions with movement, which may not be safe for the affected extremity in a cast.

4. 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.

5. Which of the following is a function of risk management?

• A. To consider the problems that arise if errors happen and their effects on the healthcare environment
• B. To identify how nursing care responds to specific client problems
• C. To view clients as customers and decide what actions will provide a satisfying healthcare experience
• D. To analyze physician-nurse relationships and determine where collaboration efforts can improve

Correct answer: A

Rationale: The function of risk management in healthcare is to assess and address potential risks that could lead to errors and their effects on the healthcare environment. This involves identifying, evaluating, and prioritizing risks to minimize their impact and prevent adverse outcomes. Choice A is correct because it aligns with the core purpose of risk management in healthcare. Choices B, C, and D are incorrect as they do not directly relate to the primary focus of risk management, which is the proactive management of risks to ensure patient safety and quality care.
