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. Which of the following interventions should the nurse implement for a client with hyperkalemia?

• A. Administer calcium gluconate
• B. Increase fluid intake to promote potassium excretion
• C. Administer a diuretic
• D. Administer sodium bicarbonate

Correct answer: A

Rationale: The correct intervention for a client with hyperkalemia is to administer calcium gluconate. Calcium gluconate helps counteract the effects of hyperkalemia by stabilizing the cardiac cell membrane. Increasing fluid intake (Choice B) may not effectively lower potassium levels. Administering a diuretic (Choice C) or sodium bicarbonate (Choice D) is not the primary treatment for hyperkalemia and may not address the immediate need to lower potassium levels.

3. A client is reinforcing teaching with a nurse about how to use an incentive spirometer. Which of the following actions by the client indicates an understanding of the teaching?

• A. The client exhales deeply before inhaling
• B. The client attempts to elevate the cylinder by inhaling deeply
• C. The client inhales quickly through the spirometer
• D. The client inhales several short breaths

Correct answer: B

Rationale: The correct answer is B because inhaling deeply and slowly elevates the cylinder on the spirometer, promoting lung expansion. Choice A is incorrect as exhaling deeply before inhaling is not the correct technique for using an incentive spirometer. Choice C is incorrect as inhaling quickly through the spirometer does not promote optimal lung expansion. Choice D is incorrect as inhaling several short breaths does not facilitate the proper use of an incentive spirometer.

4. How should a healthcare professional assess a patient for potential deep vein thrombosis (DVT)?

• A. Assess for unilateral leg swelling
• B. Encourage early mobilization
• C. Check for calf tenderness
• D. Observe for redness and warmth

Correct answer: A

Rationale: To assess a patient for potential deep vein thrombosis (DVT), healthcare professionals should look for unilateral leg swelling. This is a classic sign of DVT. While encouraging early mobilization is generally beneficial for preventing DVT, it is not a method of assessment. Checking for calf tenderness is also relevant but not as specific as unilateral leg swelling. Observing for redness and warmth can be signs of inflammation but are not as specific to DVT as unilateral leg swelling.

5. What is the first intervention for a patient in shock?

• A. Administer fluids
• B. Monitor blood pressure
• C. Provide oxygen
• D. Call for assistance

Correct answer: A

Rationale: The correct answer is to administer fluids. In a patient experiencing shock, the priority is to address inadequate perfusion by restoring circulating blood volume. Administering fluids helps improve perfusion and oxygen delivery to vital organs. Monitoring blood pressure, providing oxygen, and calling for assistance are important steps but administering fluids is the initial and most critical intervention in the management of shock.
