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 client with multiple sclerosis is being educated by the nurse on exercises and physical activities. Which statement by the client indicates a need for further teaching?

• A. "I can lift weights and engage in resistance training."?
• B. "I should exercise until I am exhausted."?
• C. "I can incorporate aerobic exercises into my routine."?
• D. "I should perform proper stretching before starting my routine."?

Correct answer: B

Rationale: The correct answer is, "I should exercise until I am exhausted."? This statement indicates a need for further teaching because patients with multiple sclerosis should avoid exercising to the point of exhaustion or fatigue. Strenuous physical activity can increase body temperature and potentially worsen symptoms in individuals with multiple sclerosis. Choice A is correct because lifting weights and resistance training can be appropriate exercises for patients with multiple sclerosis. Choice C is valid because aerobic exercises can also be beneficial. Choice D is accurate as proper stretching before starting an exercise routine is essential for preventing injuries.

3. The nurse is providing disease prevention education to a 63-year-old woman with a negative family history of breast cancer. The nurse recommends the patient schedule mammograms with which frequency?

• A. Every 5 years
• B. Every 10 years
• C. Every other year
• D. Once a year

Correct answer: C

Rationale: Mammograms, along with breast self-examinations and other routine tests, are key for the early diagnosis and treatment of breast cancer. All major societies (WHO, ACS, USPSTF) recommend a screening mammogram every two years in women of this age at average risk of breast cancer. The recommended frequency may change if there are identified family history and significant risk factors. Choosing 'Once a year' is too frequent and not aligned with current guidelines. Opting for 'Every 5 years' or 'Every 10 years' intervals is not adequate for regular breast cancer screening and may increase the risk of cancer progression. Therefore, 'Every other year' is the most appropriate choice for this patient without a family history of breast cancer.

4. A patient with Addison's disease asks a nurse for nutrition and diet advice. Which of the following diet modifications is not recommended?

• A. A diet high in grains
• B. A diet with adequate caloric intake
• C. A high protein diet
• D. A restricted sodium diet

Correct answer: D

Rationale: For a patient with Addison's disease, a restricted sodium diet is not recommended. These patients require normal dietary sodium to prevent excess fluid loss. Patients with primary adrenal insufficiency (Addison disease) should have ample access to salt because of the salt wasting that occurs if their condition is untreated. Therefore, a diet high in grains, a diet with adequate caloric intake, and a high protein diet are all recommended for patients with Addison's disease to support their nutritional needs and overall health. However, restricting sodium can be detrimental for these patients due to the nature of their condition.

5. The nurse is assessing an infant with developmental dysplasia of the hip. Which finding would the nurse anticipate?

• A. Unequal leg length
• B. Limited adduction
• C. Diminished femoral pulses
• D. Symmetrical gluteal folds

Correct answer: A

Rationale: The correct answer is 'Unequal leg length.' Shortening of a leg is a common sign of developmental dysplasia of the hip. Limited adduction (Choice B) may be present but is less specific to developmental dysplasia of the hip. Diminished femoral pulses (Choice C) are not typically associated with developmental dysplasia of the hip. Symmetrical gluteal folds (Choice D) are a normal finding and would not be expected in a patient with developmental dysplasia of the hip.
