Nursing Elites

1. What is the most important action for preventing infection in a client with a central venous catheter?

• A. Changing the catheter dressing every 72 hours.
• B. Flushing the catheter with heparin solution daily.
• C. Ensuring the catheter is clamped when not in use.
• D. Maintaining sterile technique when handling the catheter.

Correct answer: D

Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. This action helps minimize the introduction of pathogens into the catheter site, reducing the risk of contamination and subsequent infection. Changing the catheter dressing every 72 hours, while important, does not directly address the prevention of infection at the insertion site. Flushing the catheter with heparin solution daily helps prevent occlusion but does not primarily focus on infection prevention. Ensuring the catheter is clamped when not in use is essential for preventing air embolism but does not directly relate to infection control.

2. The healthcare provider attaches a pulse oximeter to a client's fingers and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?

• A. BP 142/88 mmHg
• B. 2+ edema of fingers and hands
• C. Radial pulse volume is +3
• D. Capillary refill time is 2 seconds

Correct answer: B

Rationale: Edema, indicated by 2+ edema of fingers and hands, can impair blood flow and peripheral perfusion, leading to reduced oxygen saturation readings on a pulse oximeter. High blood pressure (choice A) would not directly affect oxygen saturation readings. Radial pulse volume (choice C) and capillary refill time (choice D) are more related to assessing circulation rather than contributing significantly to oxygen saturation readings.

3. During a physical assessment, a nurse is assessing 4 adult clients. Which of the following physical assessment techniques should the nurse use?

• A. Ensure the bladder of the BP cuff surrounds 80% of their arm.
• B. Use the BP cuff on the forearm if the upper arm is not accessible.
• C. Apply the BP cuff loosely around the arm.
• D. Use a pediatric cuff for adults with small arms.

Correct answer: A

Rationale: The correct answer is to ensure the bladder of the BP cuff surrounds 80% of the arm. This technique is crucial for obtaining accurate blood pressure readings. Choice B is incorrect because using the BP cuff on the forearm may lead to inaccurate readings. Choice C is incorrect as applying the BP cuff loosely can also result in inaccurate measurements. Choice D is incorrect because using a pediatric cuff for adults with small arms would not provide accurate blood pressure readings.

4. A nurse is in a public building when someone cries out, 'Help! I think he is having a heart attack!' The nurse responds to the scene and finds the unconscious adult lying on the floor. Another bystander has obtained an AED. The nurse's first action, after ensuring someone has called for EMS, should be to:

• A. Administer cardiac compressions
• B. Attach the AED pads to the client
• C. Check for a pulse
• D. Perform rescue breaths

Correct answer: A

Rationale: In a scenario where a person is unconscious and there is an indication of a possible heart attack, the immediate priority for the nurse should be to administer cardiac compressions. This action helps maintain circulation and ensures oxygenated blood reaches vital organs until the AED is available. Checking for a pulse or performing rescue breaths may delay essential circulation support, and attaching AED pads should follow the initial step of administering compressions to maximize the chances of a successful resuscitation.

5. The patient has undergone surgery for a broken leg and has a cast in place. What should the nurse do to prevent skin impairment?

• A. Assess surfaces exposed to the edges of the cast for pressure areas.
• B. Keep the patient's blood pressure low to prevent overperfusion of tissue.
• C. Allow turning in bed to prevent complications.
• D. Encourage the patient's dietary intake to maintain hydration.

Correct answer: A

Rationale: To prevent skin impairment in a patient with a cast, the nurse should assess surfaces exposed to the edges of the cast for pressure areas. This is important to prevent pressure ulcers or skin breakdown. Keeping the patient's blood pressure low (Choice B) is not directly related to preventing skin impairment in this scenario. Allowing turning in bed (Choice C) is essential for preventing complications like pressure ulcers and is not contraindicated. Encouraging the patient's dietary intake (Choice D) to maintain hydration is not directly related to preventing skin impairment associated with a cast.
