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 32-year-old pregnant woman comes to the clinic for her prenatal visit. The nurse gathers data about her obstetric history, which includes 3-year-old twins at home and a miscarriage 10 years ago at 12 weeks gestation. How would the nurse accurately document this information?

• A. G4 T1 P0 A1 L2
• B. G3 T1 P0 A1 L2
• C. G3 T0 P1 A1 L2
• D. G4 T0 P1 A1 L2

Correct answer: D

Rationale: The correct answer is G4 T1 P0 A1 L2. This documentation accurately represents the woman's obstetric history. G4: She is currently pregnant (1), has twins (1), and had a miscarriage (1), totaling four pregnancies. T1: She has had one pregnancy that resulted in the birth of her twins at term. P0: She has not had any preterm births. A1: She had one miscarriage at 12 weeks gestation. L2: She has two living children (the twins). Therefore, the correct documentation reflects all aspects of her obstetric history as provided.

3. A client is admitted with the diagnosis of pulmonary embolism. While taking a history, the client tells the nurse he was admitted for the same thing twice before, the last time just 3 months ago. The nurse would anticipate the healthcare provider ordering:

• A. Pulmonary embolectomy
• B. Vena caval interruption
• C. Increasing the coumadin therapy to achieve an INR of 3-4
• D. Thrombolytic therapy

Correct answer: B

Rationale: In the case of a client with a history of recurrent pulmonary embolism or contraindications to heparin, vena caval interruption may be necessary. Vena caval interruption involves placing a filter device in the inferior vena cava to prevent clots from traveling to the pulmonary circulation. Pulmonary embolectomy is a surgical procedure to remove a clot from the pulmonary artery, which is usually considered in severe or life-threatening cases. Increasing coumadin therapy to achieve a higher INR may be an option but vena caval interruption would be more appropriate in this scenario. Thrombolytic therapy is used in acute cases of pulmonary embolism to dissolve the clot rapidly, but in a recurrent case with contraindications to anticoagulants, vena caval interruption would be a preferred intervention.

4. The BRAT diet is often prescribed for patients with gastroenteritis. This acronym stands for:

• A. Bananas, Rice, Applesauce, and Toast
• B. Bread, Rice, Apricots, and Tapioca
• C. Bananas, Rolls, Apricots, and Toast
• D. Bananas, Rolls, Applesauce, and Tapioca

Correct answer: A

Rationale: The BRAT diet, which stands for Bananas, Rice, Applesauce, and Toast, is commonly recommended for patients with gastroenteritis. These easily digestible foods help firm up stools due to their low fiber content and provide essential nutrients lost during vomiting and diarrhea. Choice B is incorrect because it includes apricots, which are not part of the traditional BRAT diet. Choice C is incorrect as it includes rolls, which are not typically included in the BRAT diet. Choice D is incorrect as it includes tapioca, which is not part of the traditional BRAT diet. Therefore, the correct answer is Bananas, Rice, Applesauce, and Toast.

5. One of the complications of complete bed rest and immobility is which of the following?

• A. Plantar flexion
• B. Dorsiflexion
• C. Extension contractures
• D. Adduction contractures

Correct answer: A

Rationale: Plantar flexion, or foot drop, is a common complication of complete bed rest and immobility. This condition occurs due to the weakening of muscles that lift the foot, leading to the foot dragging or being unable to clear the ground during walking. Dorsiflexion refers to moving the foot upwards, which is not a typical complication of immobility. Extension contractures involve the inability to fully extend a joint, while adduction contractures refer to the inability to move a limb away from the body. These types of contractures can also occur with immobility, but they are not specifically associated with foot drop.
