Nursing Elites

1. A client has a central venous catheter. Which of the following actions should be taken to prevent an air embolism?

• A. Keep the catheter clamped when not in use
• B. Have the client perform the Valsalva maneuver while the catheter is removed
• C. Use a non-coring needle to access the catheter
• D. Flush the catheter with 0.9% sodium chloride every 24 hours

Correct answer: B

Rationale: The correct action to prevent an air embolism in a client with a central venous catheter is to have the client perform the Valsalva maneuver while the catheter is removed. This maneuver helps to close the airway and prevent air from entering the bloodstream. Keeping the catheter clamped at all times (Choice A) is not necessary and may lead to clot formation. Using a non-coring needle (Choice C) is important for accessing the catheter but does not specifically prevent air embolism. Flushing the catheter with 0.9% sodium chloride (Choice D) helps maintain patency but does not directly prevent air embolism.

2. A nurse is assessing a client who has hyperthyroidism. Which of the following findings should the nurse expect?

• A. Weight gain.
• B. Dry skin.
• C. Cold intolerance.
• D. Tachycardia.

Correct answer: D

Rationale: The correct answer is D: Tachycardia. In clients with hyperthyroidism, tachycardia is a common finding due to the increased metabolic rate. Weight loss and heat intolerance are also expected due to the elevated metabolism. Choices A, B, and C (Weight gain, dry skin, cold intolerance) are not typical findings in hyperthyroidism, as the condition is associated with an overactive thyroid gland leading to an increase in metabolic functions.

3. A nurse is providing teaching to a client who has a new prescription for warfarin. Which of the following statements indicates a need for further teaching?

• A. I will take warfarin every other day.
• B. I will eat more leafy green vegetables while taking warfarin.
• C. I will use a soft toothbrush while taking warfarin.
• D. I will have my INR checked regularly while taking warfarin.

Correct answer: B

Rationale: The correct answer is B. Eating more leafy green vegetables can increase vitamin K intake, which may reduce the effectiveness of warfarin. This can lead to fluctuations in the International Normalized Ratio (INR) levels, affecting the medication's efficacy. Choices A, C, and D are correct statements. Taking warfarin every other day, using a soft toothbrush to prevent gum bleeding, and having regular INR checks are all appropriate and important actions when taking warfarin.

4. A client who has a prescription for insulin glargine is talking to a nurse. Which of the following statements by the client indicates an understanding of the teaching?

• A. I will mix this insulin with my regular insulin before injecting it.
• B. I will store this insulin in the refrigerator after opening it.
• C. I will take this insulin twice a day.
• D. I will inject this insulin when my blood glucose is above 200 mg/dL.

Correct answer: B

Rationale: The correct answer is B because insulin glargine should be stored in the refrigerator after opening to maintain its potency. Choice A is incorrect as insulin glargine should not be mixed with other insulins. Choice C is incorrect because insulin glargine is typically taken once a day. Choice D is incorrect because insulin glargine is usually taken regardless of blood glucose levels.

5. A client has had vomiting and diarrhea for the past 3 days. Which of the following findings indicates the client is experiencing fluid volume deficit?

• A. Jugular vein distention
• B. Bradycardia
• C. Increased respiratory rate
• D. Bounding pulses

Correct answer: C

Rationale: An increased respiratory rate is a sign of fluid volume deficit as the body attempts to compensate for decreased blood volume. Jugular vein distention, bradycardia, and bounding pulses are not typical findings of fluid volume deficit. Jugular vein distention is more commonly associated with fluid volume overload, bradycardia can be a sign of fluid volume excess or other issues, and bounding pulses are not typically seen in fluid volume deficit.
