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. A client has a sodium level of 125. What findings should the nurse expect?

• A. Abdominal cramping
• B. Elevated blood pressure
• C. Decreased heart rate
• D. Increased thirst

Correct answer: A

Rationale: Low sodium levels (hyponatremia) often present with various symptoms, including abdominal cramping. Abdominal cramping is a common manifestation of hyponatremia due to the altered electrolyte balance. Option B ('Elevated blood pressure') is incorrect because low sodium levels typically lead to decreased blood pressure, not elevated. Option C ('Decreased heart rate') is incorrect as low sodium levels are more likely to cause an irregular heart rate rather than a decreased heart rate. Option D ('Increased thirst') is incorrect because excessive thirst is more commonly associated with high sodium levels (hypernatremia) rather than low sodium levels.

3. A health care provider has prescribed isoniazid (Laniazid) for a client. Which instruction should the LPN give the client about this medication?

• A. Prolonged use does not typically cause dark concentrated urine.
• B. It is not necessary to take the medication on an empty stomach for optimal absorption.
• C. Avoid taking the medication with aluminum hydroxide to minimize GI upset.
• D. Drinking alcohol daily can cause drug-induced hepatitis.

Correct answer: D

Rationale: The correct answer is D. When taking isoniazid, alcohol consumption should be avoided as it can increase the risk of liver damage, potentially leading to drug-induced hepatitis. Choices A, B, and C are incorrect. Prolonged use of isoniazid does not typically cause dark concentrated urine; it is not necessary to take the medication on an empty stomach for optimal absorption; and it is not recommended to take isoniazid with aluminum hydroxide to minimize GI upset.

4. A client has an indwelling urinary catheter. Which of the following assessment findings indicates that the catheter requires irrigation?

• A. Bladder scan shows 525 mL of urine
• B. Urine has a strong odor
• C. The client reports abdominal discomfort
• D. The catheter is blocked or not draining

Correct answer: D

Rationale: The correct answer is D because if the catheter is blocked or not draining, it may need irrigation to restore proper flow. Option A, 'Bladder scan shows 525 mL of urine,' does not necessarily indicate the need for irrigation as it could be within the expected range for catheter drainage. Option B, 'Urine has a strong odor,' may indicate a urinary tract infection but does not directly correlate with the need for catheter irrigation. Option C, 'The client reports abdominal discomfort,' could indicate various issues but does not specifically suggest the need for catheter irrigation.

5. A healthcare professional is preparing to perform a sterile dressing change for a client. Which of the following actions should the healthcare professional plan to take?

• A. Don sterile gloves after opening sterile dressing supplies
• B. Set up the sterile field at waist level
• C. Consider the entire border of the sterile field as contaminated
• D. Place the cap of a sterile solution inside the sterile field

Correct answer: B

Rationale: Setting up the sterile field at waist level is crucial to maintaining its sterility during a dressing change. Choice A is incorrect because sterile gloves should be worn after opening sterile dressing supplies to prevent contamination. Choice C is incorrect as the entire border of the sterile field should be considered contaminated to maintain sterility. Choice D is incorrect because the cap of a sterile solution should never be placed inside the sterile field to prevent contamination.
