Nursing Elites

1. A 67-year-old client is admitted with substernal chest pain with radiation to the jaw. His admitting diagnosis is Acute Myocardial Infarction (MI). The priority nursing diagnosis for this client during the immediate 24 hours is

• A. Constipation related to immobility
• B. High risk for infection
• C. Impaired gas exchange
• D. Fluid volume deficit

Correct answer: C

Rationale: The correct answer is C: Impaired gas exchange. In a client with an acute myocardial infarction, impaired gas exchange is a priority nursing diagnosis due to compromised heart function, which affects oxygenated blood circulation. Close monitoring and interventions are crucial to ensure adequate oxygenation. Choices A, B, and D are incorrect: A) Constipation related to immobility is not the priority in this acute situation; B) High risk for infection is not the immediate concern related to the client's primary diagnosis; D) Fluid volume deficit, while important, is not the priority compared to addressing impaired gas exchange in acute MI.

2. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). The nurse should monitor the client for which of the following laboratory values?

• A. Prothrombin time (PT)
• B. Serum potassium
• C. Blood urea nitrogen (BUN)
• D. White blood cell count (WBC)

Correct answer: A

Rationale: The correct answer is A: Prothrombin time (PT). Prothrombin time is monitored to assess the effectiveness of warfarin therapy. Warfarin is an anticoagulant medication that works by inhibiting the synthesis of vitamin K-dependent clotting factors, including factors II, VII, IX, and X. Monitoring the PT helps ensure that the client's blood is clotting within the desired therapeutic range to prevent complications such as recurrent DVT or excessive bleeding. Choices B, C, and D are incorrect because serum potassium, blood urea nitrogen, and white blood cell count are not directly related to monitoring warfarin therapy in a client with a history of DVT.

3. What is the main focus of secondary prevention?

• A. Early detection and treatment
• B. Rehabilitation
• C. Health promotion
• D. Palliative care

Correct answer: A

Rationale: The main focus of secondary prevention is early detection and treatment of disease. This approach aims to identify health conditions in their early stages when they are easier to treat or manage effectively. Choice B, rehabilitation, is more aligned with restoring function after an illness or injury has occurred. Choice C, health promotion, concentrates on educating and empowering individuals to adopt healthy behaviors to prevent the onset of diseases. Choice D, palliative care, is focused on providing comfort and improving the quality of life for individuals with serious illnesses or at the end of life, rather than on early detection and treatment.

4. Which individual has the highest risk of developing community-acquired pneumonia?

• A. A 40-year-old first-grade teacher who works with underprivileged children.
• B. A 75-year-old retired secretary with exercise-induced wheezing.
• C. A 60-year-old homeless person who is an alcoholic and smokes.
• D. A 35-year-old aerobics instructor who skips meals and eats only vegetables.

Correct answer: C

Rationale: The correct answer is the 60-year-old homeless person who is an alcoholic and smokes. This individual has the highest risk of developing community-acquired pneumonia due to factors such as homelessness, alcoholism, and smoking, which weaken the immune system and make them more susceptible to respiratory infections. Choice A is incorrect as working with underprivileged children, while potentially exposing the individual to various illnesses, does not directly increase the risk of pneumonia. Choice B is less likely as exercise-induced wheezing may suggest asthma but does not directly correlate with pneumonia risk. Choice D, an aerobics instructor who eats only vegetables and skips meals, does not have the same level of risk factors for pneumonia as the homeless person in choice C.

5. The nurse is caring for a client on mechanical ventilation. When performing endotracheal suctioning, the nurse will avoid hypoxia by

• A. Inserting a fenestrated catheter with a whistle tip without suction
• B. Completing the suction pass in 30 seconds with a pressure of 150 mm Hg
• C. Hyperoxygenating with 100% O2 for 1 to 2 minutes before and after each suction pass
• D. Minimizing the suction pass to 60 seconds while slowly rotating the lubricated catheter

Correct answer: C

Rationale: Hyperoxygenating the client before and after suctioning helps prevent hypoxia by ensuring adequate oxygen levels during the procedure, which briefly interrupts the client's normal breathing pattern. Choice A is incorrect because inserting a fenestrated catheter with a whistle tip without suction would not prevent hypoxia. Choice B is incorrect as completing the suction pass in 30 seconds with a pressure of 150 mm Hg may lead to hypoxia. Choice D is incorrect as minimizing the suction pass to 60 seconds may not provide enough time for effective suctioning and could lead to hypoxia.
