Nursing Elites

1. What is a key nursing action for a client with a wound infection?

• A. Change the dressing daily
• B. Perform a wound culture before applying antibiotics
• C. Cleanse the wound with alcohol-based solutions
• D. Apply a wet-to-dry dressing to the wound

Correct answer: B

Rationale: Performing a wound culture before applying antibiotics is crucial for determining the specific type of infection present and selecting the most effective antibiotic treatment. Changing the dressing daily (Choice A) is a routine wound care practice but may not address the root cause of the infection. Cleansing the wound with alcohol-based solutions (Choice C) can be too harsh and delay wound healing. Applying a wet-to-dry dressing (Choice D) is an outdated practice that can cause trauma to the wound bed and hinder the healing process.

2. 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.

3. What are common signs of hypoglycemia?

• A. Shakiness or Tremors
• B. Sweating
• C. Hunger
• D. Confusion or Irritability

Correct answer: A

Rationale: The correct signs of hypoglycemia include shakiness or tremors, sweating, and hunger. These symptoms indicate low blood sugar levels. Confusion or irritability are more associated with severe hypoglycemia, while the immediate treatment for hypoglycemia involves providing a source of glucose to raise blood sugar levels quickly.

4. What are the signs and symptoms of a pulmonary embolism?

• A. Sudden shortness of breath
• B. Chest pain
• C. Cough with blood
• D. All of the above

Correct answer: D

Rationale: A pulmonary embolism can manifest with sudden shortness of breath, chest pain, and coughing up blood. These symptoms are classic presentations of a pulmonary embolism due to the blockage of blood flow to the lungs. Therefore, the correct answer is 'All of the above.' Each symptom alone can be seen in various other conditions, but when occurring together, they strongly suggest a pulmonary embolism. Sudden shortness of breath is due to decreased oxygenation, chest pain can result from the strain on the heart, and coughing with blood may indicate damage to the lung tissue. Choosing any single symptom would not encompass the full range of presentations seen in a pulmonary embolism.

5. What are the signs and symptoms of fluid overload?

• A. Edema, shortness of breath, weight gain
• B. High blood pressure and jugular venous distention
• C. Low blood pressure and cyanosis
• D. Tachycardia and dizziness

Correct answer: A

Rationale: The correct signs and symptoms of fluid overload include edema, shortness of breath, and weight gain. Edema is the abnormal accumulation of fluid causing swelling, shortness of breath can occur due to fluid accumulating in the lungs, and weight gain is often seen as a result of excess fluid retention. Choices B, C, and D are incorrect because high blood pressure and jugular venous distention are more indicative of conditions like heart failure, while low blood pressure and cyanosis are seen in conditions like shock or poor perfusion. Tachycardia and dizziness are not typical signs of fluid overload.
