Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory test should the nurse monitor to determine the effectiveness of the medication?

• A. Platelet count.
• B. Prothrombin time (PT) and international normalized ratio (INR).
• C. Activated partial thromboplastin time (aPTT).
• D. Fibrinogen level.

Correct answer: B

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of warfarin (Coumadin) therapy. These tests help assess the clotting time and the desired anticoagulant effect of the medication. Monitoring PT and INR levels is crucial to ensure that the client is within the therapeutic range, reducing the risk of bleeding or clotting complications associated with warfarin therapy. Platelet count (Choice A) measures the number of platelets in the blood and is not specific for monitoring warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice C) is more commonly used to monitor heparin therapy, not warfarin. Fibrinogen level (Choice D) assesses the amount of fibrinogen in the blood and is not a specific test for monitoring warfarin therapy.

2. A client with myelogenous leukemia is receiving an autologous bone marrow transplantation (BMT). What is the priority intervention that the nurse should implement when the bone marrow is repopulating?

• A. Administer sargramostim (Leukine, Prokine).
• B. Infuse PRBC and platelet transfusions.
• C. Give parenteral prophylactic antibiotics.
• D. Maintain a protective isolation environment.

Correct answer: D

Rationale: Maintaining a protective isolation environment is crucial during the repopulation of bone marrow post-transplant to reduce the risk of infections. The client's immune system is compromised during this period, making them highly susceptible to infections. By implementing protective isolation measures, the nurse can help prevent exposure to pathogens, safeguarding the client's health and supporting the success of the transplantation.

3. A patient with chronic kidney disease (CKD) is prescribed erythropoietin. What is the primary action of this medication?

• A. Stimulate white blood cell production
• B. Increase platelet count
• C. Promote red blood cell production
• D. Enhance clotting factor production

Correct answer: C

Rationale: Erythropoietin primarily stimulates the bone marrow to produce more red blood cells, which helps to improve oxygen delivery to tissues. In chronic kidney disease, patients often develop anemia due to reduced erythropoietin production by the kidneys. By administering exogenous erythropoietin, the deficient hormone is replaced, leading to an increase in red blood cell production and subsequently improving the oxygen-carrying capacity of the blood.

4. The healthcare provider is assessing a client with chronic obstructive pulmonary disease (COPD). Which finding should the provider expect?

• A. Increased anteroposterior chest diameter.
• B. Decreased respiratory rate.
• C. Dull percussion sounds over the lungs.
• D. Hyperresonance on chest percussion.

Correct answer: A

Rationale: The correct answer is A: Increased anteroposterior chest diameter. The increased anteroposterior chest diameter, often referred to as a barrel chest, is a common finding in clients with COPD due to hyperinflation of the lungs. This occurs because of the loss of lung elasticity and air trapping, leading to a more rounded chest shape. Choices B, C, and D are incorrect. Decreased respiratory rate is not typically associated with COPD; instead, an increased respiratory rate may be seen due to the body's compensatory mechanisms. Dull percussion sounds and hyperresonance on chest percussion are not characteristic findings in COPD. Dull percussion sounds may be indicative of consolidation or pleural effusion, while hyperresonance is more commonly associated with conditions like emphysema.

5. When should surgical correction of hypospadias typically occur for a newborn infant as advised by the nurse?

• A. Repair should be done within one month to prevent bladder infections.
• B. Repairs should typically be done before the child is potty-trained.
• C. Delaying the repair until school age reduces castration fears.
• D. To form a proper urethra repair, it should be done after sexual maturity.

Correct answer: B

Rationale: Surgical repair of hypospadias is recommended to be performed before the child is potty-trained to prevent complications. Early correction helps in achieving better outcomes and reduces the risk of issues related to urination and development of the genitalia.
