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. What intervention is essential for a client with dehydration?

• A. Monitor electrolyte levels regularly
• B. Administer oral rehydration solutions
• C. Increase fluid intake to maintain hydration
• D. Administer intravenous fluids to treat dehydration

Correct answer: B

Rationale: Administering oral rehydration solutions is essential for a client with dehydration as it helps replenish lost fluids and electrolytes directly through the oral route. Monitoring electrolyte levels regularly (Choice A) is important but not as essential as providing immediate rehydration. Increasing fluid intake to maintain hydration (Choice C) may not be sufficient for a client already dehydrated and needing rapid replenishment. Administering intravenous fluids (Choice D) is a more invasive intervention typically reserved for severe cases of dehydration or when the client cannot tolerate oral fluids.

3. How should a healthcare provider assess a patient with potential diabetic ketoacidosis (DKA)?

• A. Monitor blood glucose and check for ketones in urine
• B. Administer insulin and provide fluids
• C. Administer potassium and check for electrolyte imbalance
• D. Administer sodium bicarbonate and monitor urine output

Correct answer: A

Rationale: Correct answer: To assess a patient with potential diabetic ketoacidosis (DKA), healthcare providers should monitor blood glucose and check for ketones in the urine. Elevated blood glucose levels and the presence of ketones in urine are indicative of DKA. Choice B is incorrect because administering insulin and providing fluids are treatments for DKA rather than assessment measures. Choice C is incorrect as administering potassium and checking for electrolyte imbalance are interventions related to managing DKA complications, not initial assessment. Choice D is incorrect because administering sodium bicarbonate and monitoring urine output are not primary assessment actions for DKA.

4. A nurse is teaching a client who has chronic obstructive pulmonary disease (COPD) about breathing exercises. Which of the following instructions should the nurse include?

• A. Use abdominal breathing during physical activity
• B. Inhale quickly and deeply through the nose
• C. Use pursed-lip breathing during physical activity
• D. Breathe quickly and deeply during exercise

Correct answer: C

Rationale: The correct answer is C: 'Use pursed-lip breathing during physical activity.' Pursed-lip breathing is a beneficial technique for clients with COPD as it helps improve airflow by keeping the airways open longer. Choice A is incorrect as abdominal breathing may not be as effective in COPD as pursed-lip breathing. Choice B, inhaling quickly and deeply through the nose, is not recommended as it can lead to hyperventilation. Choice D, breathing quickly and deeply during exercise, is also not suitable for clients with COPD as it can cause increased shortness of breath.

5. What is the appropriate action for a healthcare professional when administering a blood transfusion?

• A. Verify the patient's identity
• B. Monitor vital signs
• C. Stay with the patient during the first 15 minutes
• D. Stop the transfusion if a reaction occurs

Correct answer: A

Rationale: The appropriate action for a healthcare professional when administering a blood transfusion is to verify the patient's identity. This step is essential to ensure that the correct blood product is given to the right patient, preventing any errors or adverse reactions. While monitoring vital signs and staying with the patient during the initial phase of the transfusion are also important steps, the primary action of verifying the patient's identity takes precedence to uphold patient safety and prevent any potential harm.
