Nursing Elites

1. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin. Which laboratory value should the nurse monitor to assess the therapeutic effect of this medication?

• A. Platelet count
• B. Prothrombin time (PT)
• C. White blood cell count
• D. Hemoglobin level

Correct answer: B

Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.

2. The nurse is caring for a client with a suspected myocardial infarction (MI). Which laboratory test result is most indicative of a recent MI?

• A. Elevated troponin levels
• B. Increased white blood cell count
• C. Increased lactate dehydrogenase (LDH)
• D. Elevated C-reactive protein (CRP)

Correct answer: A

Rationale: Elevated troponin levels are the most specific and sensitive indicator of myocardial infarction. Troponin levels increase within hours of an MI and remain elevated for several days. White blood cell count, lactate dehydrogenase (LDH), and C-reactive protein (CRP) are not specific markers for MI. An increased white blood cell count may indicate inflammation or infection, increased LDH levels can be seen in various conditions like liver disease or muscle injury, and elevated CRP is a general marker of inflammation rather than specific to MI.

3. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?

• A. To reduce abdominal pressure on the diaphragm
• B. To promote oxygenation by improving lung expansion
• C. To encourage use of accessory muscles for breathing
• D. To drain secretions and prevent aspiration

Correct answer: D

Rationale: Elevating the head of the bed in a client with acute respiratory distress syndrome (ARDS) is essential to drain secretions and prevent aspiration. This position helps facilitate the removal of secretions from the airways, reducing the risk of aspiration pneumonia. Choices A, B, and C are incorrect as the primary reason for elevating the head of the bed in ARDS is to assist with secretion drainage and prevent complications associated with aspiration.

4. While assessing a client who is admitted with heart failure and pulmonary edema, the nurse identifies dependent peripheral edema, an irregular heart rate, and a persistent cough that produces pink blood-tinged sputum. After initiating continuous telemetry and positioning the client, which intervention should the nurse implement?

• A. Administer prescribed diuretics
• B. Prepare for intubation
• C. Notify the healthcare provider immediately
• D. Obtain sputum sample

Correct answer: D

Rationale: The client's cough producing pink, frothy sputum is indicative of pulmonary edema, which needs immediate treatment. Obtaining a sputum sample helps identify any infection that may be contributing to the pulmonary issues. Administering diuretics is essential in managing pulmonary edema but obtaining a sputum sample should take priority. Intubation may be necessary in severe cases but is not the initial intervention. Notifying the healthcare provider is important, but immediate action to diagnose and treat the condition is crucial.

5. During an initial assessment, a healthcare provider notes that a client has elevated blood pressure. Which of the following findings is considered a major risk factor for coronary artery disease?

• A. Elevated HDL cholesterol
• B. Low LDL cholesterol
• C. Elevated blood pressure
• D. Low triglyceride levels

Correct answer: C

Rationale: Elevated blood pressure is a significant risk factor for coronary artery disease because it increases the strain on the arteries, leading to potential damage and a higher risk of developing coronary artery disease. Elevated HDL cholesterol (Choice A) is actually considered beneficial as it helps reduce the risk of heart disease. Low LDL cholesterol (Choice B) is also beneficial as high levels of LDL are associated with an increased risk of coronary artery disease. Low triglyceride levels (Choice D) are not typically considered a major risk factor for coronary artery disease.
