Nursing Elites

1. What is the proper technique for obtaining a blood specimen from a central venous line?

• A. Use sterile gloves and discard the first 10 mL of blood
• B. Flush the line with heparin and then draw the specimen
• C. Draw the specimen and then administer heparin
• D. Use non-sterile gloves to reduce contamination risk

Correct answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.

2. A nurse is caring for a client following an acute myocardial infarction who is concerned about fatigue. What is the best strategy to promote independence in self-care?

• A. Instruct the client to remain in bed until the fatigue resolves
• B. Encourage the client to gradually resume self-care tasks with frequent rest periods
• C. Assign assistive personnel to perform all self-care tasks for the client
• D. Ask the client's family to assist with self-care

Correct answer: B

Rationale: Encouraging the client to gradually resume self-care tasks with frequent rest periods is the best strategy to promote independence while managing fatigue. This approach allows the client to regain confidence in their abilities and fosters independence. Option A is incorrect as prolonged bed rest can lead to deconditioning and worsen fatigue. Option C is not promoting independence as it involves delegating all self-care tasks to others. Option D involves family assistance, which may be helpful but does not directly promote the client's independence in self-care.

3. What is the main symptom of left-sided heart failure?

• A. Shortness of breath
• B. Edema
• C. Increased heart rate
• D. Decreased urine output

Correct answer: A

Rationale: Shortness of breath is the main symptom of left-sided heart failure because it results from pulmonary congestion due to fluid buildup in the lungs. Edema, increased heart rate, and decreased urine output are associated with right-sided heart failure rather than left-sided heart failure.

4. Which nursing action is a priority when caring for a client with heart failure?

• A. Encourage the client to drink fluids frequently
• B. Weigh the client daily to monitor fluid balance
• C. Increase fluid intake to prevent dehydration
• D. Limit the client's sodium intake

Correct answer: B

Rationale: Weighing the client daily is a priority action when caring for a client with heart failure because it helps monitor fluid balance. This monitoring is essential in managing heart failure as it allows healthcare providers to assess for signs of fluid retention or depletion, which are crucial in adjusting treatment plans. Encouraging the client to drink fluids frequently (Choice A) may worsen fluid overload in heart failure patients. Increasing fluid intake (Choice C) can exacerbate fluid retention. While limiting sodium intake (Choice D) is important in heart failure management, monitoring fluid balance through daily weighing takes precedence as a priority nursing action.

5. A client is constipated and asks the nurse for advice. What should the nurse recommend?

• A. Administer a laxative to relieve discomfort
• B. Increase dietary fiber to promote bowel movements
• C. Advise the client to rest until symptoms resolve
• D. Encourage bed rest to allow bowel function to return

Correct answer: B

Rationale: The correct recommendation for constipation is to increase dietary fiber to promote bowel movements. Dietary fiber helps add bulk to the stool, making it easier to pass and promoting regular bowel movements. Administering a laxative (Choice A) is not the first-line recommendation and should be used cautiously due to potential side effects. Resting until symptoms resolve (Choice C) and encouraging bed rest (Choice D) are not effective interventions for relieving constipation.
