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. Thrombolytic therapy is frequently used in the treatment of suspected stroke. Which of the following is a significant complication associated with thrombolytic therapy?

• A. Air embolism.
• B. Cerebral hemorrhage.
• C. Expansion of the clot.
• D. Resolution of the clot.

Correct answer: B

Rationale: Cerebral hemorrhage is a significant complication associated with thrombolytic therapy in stroke treatment. Thrombolytic therapy aims to dissolve clots, but it increases the risk of bleeding, including cerebral hemorrhage. This risk is especially high when the therapy is administered quickly after a stroke, sometimes before confirming the type of stroke. Air embolism (Choice A) is not a common complication of thrombolytic therapy. Expansion of the clot (Choice C) and resolution of the clot (Choice D) are not expected outcomes of thrombolytic therapy; the therapy is specifically used to dissolve clots, not to expand or resolve them.

3. Mr. G has been admitted to the hospital with a head injury after a 12-foot fall. Which of the following nursing interventions is most appropriate when monitoring intracranial pressure?

• A. Administer hypotonic solutions
• B. Keep the head of the bed elevated
• C. Increase the client's core body temperature to 99.9 degrees
• D. Administer corticosteroids as ordered

Correct answer: D

Rationale: Administering corticosteroids as ordered is appropriate when monitoring intracranial pressure in clients at risk of increased pressure to reduce brain tissue swelling. Elevating the head of the bed helps in managing intracranial pressure by promoting venous drainage. Administering hypertonic solutions is used to reduce brain edema and control intracranial pressure. Increasing the client's core body temperature is not recommended as it can exacerbate brain injury. Corticosteroids are not routinely used for all head injuries but may be indicated in specific cases, such as certain types of brain injuries where swelling needs to be controlled.

4. A patient born in 1955 had hepatitis A infection 1 year ago. According to Centers for Disease Control and Prevention (CDC) guidelines, which action should the nurse include in care when the patient is seen for a routine annual physical exam?

• A. Start the hepatitis B immunization series.
• B. Teach the patient about hepatitis A immune globulin.
• C. Ask whether the patient has been screened for hepatitis C.
• D. Test for anti-hepatitis-A virus immune globulin M (anti-HAV-IgM).

Correct answer: C

Rationale: The correct action for the nurse to include in care when the patient is seen for a routine annual physical exam, according to CDC guidelines, is to ask whether the patient has been screened for hepatitis C. CDC guidelines recommend screening patients born between 1945 and 1965 for hepatitis C due to the high prevalence of undiagnosed cases in this age group. Starting the hepatitis B immunization series is not necessary as the patient already had hepatitis A infection. Teaching the patient about hepatitis A immune globulin is not indicated in this scenario. Testing for anti-hepatitis-A virus immune globulin M (anti-HAV-IgM) is not needed as the patient has already had hepatitis A.

5. In a clinic in a primarily African American community, a higher incidence of uncontrolled hypertension is noted in patients. To correct this health disparity, what should the nurse do first?

• A. Initiate a regular home-visit program by clinic nurses.
• B. Schedule teaching sessions about low-salt diets at community events.
• C. Assess the perceptions of community members about the care at the clinic.
• D. Obtain low-cost antihypertensive drugs using government grant funding.

Correct answer: C

Rationale: To address the higher incidence of uncontrolled hypertension in the primarily African American community, the nurse should first assess the perceptions of community members about the care at the clinic. Understanding the community's perspective can provide valuable insights into the reasons behind the health disparity. Initiating a regular home-visit program or scheduling teaching sessions about low-salt diets are important interventions but should come after gathering information on community perceptions. Obtaining low-cost antihypertensive drugs is not the initial priority; understanding community perspectives is crucial for developing effective interventions.
