Nursing Elites

1. A client is to have mafenide (Sulfamylon) cream applied to burned areas. For which serious side effect of mafenide therapy should the LPN/LVN monitor this client?

• A. Curling ulcer
• B. Renal shutdown
• C. Metabolic acidosis
• D. Hemolysis of red blood cells

Correct answer: C

Rationale: Corrected Rationale: Metabolic acidosis is a serious side effect of mafenide therapy that should be closely monitored. Mafenide can lead to metabolic acidosis due to its inhibition of carbonic anhydrase, resulting in the accumulation of carbonic acid. Curling ulcer (Choice A) is a stress-related mucosal lesion that occurs in the duodenum, primarily due to severe burns, not directly related to mafenide therapy. Renal shutdown (Choice B) is not a common side effect of mafenide therapy. Hemolysis of red blood cells (Choice D) is not a recognized side effect of mafenide cream application.

2. When caring for an older adult client who becomes agitated when asked to remove dentures before surgery, which of the following responses should the nurse make?

• A. "What worries you about being without your teeth?"
• B. "You need to follow the preoperative instructions and remove your dentures."
• C. "It's important to remove dentures to ensure proper fitting of the mask during anesthesia."
• D. "I will explain why dentures need to be removed before surgery."

Correct answer: A

Rationale: The correct response is to ask the client about their concerns regarding being without their teeth. This approach helps address the client's anxiety and provides insight into the reason for their agitation. Choice B is authoritarian and does not address the client's emotional needs. Choice C focuses on the technical aspect of surgery and does not address the client's emotional state. Choice D implies a one-way communication without addressing the client's feelings or concerns.

3. A client with a diagnosis of hypertension is being assessed. Which symptom would be most concerning?

• A. Headache
• B. Blurred vision
• C. Dizziness
• D. Chest pain

Correct answer: D

Rationale: Chest pain in a client with hypertension is the most concerning symptom as it may indicate a myocardial infarction or other serious cardiac event related to hypertension. Immediate intervention is required to address potential life-threatening conditions. Headache, blurred vision, and dizziness are common symptoms associated with hypertension but are not typically indicative of an acute cardiac event requiring urgent attention.

4. When assisting an 82-year-old client to ambulate, it is important for the LPN/LVN to realize that the center of gravity for an elderly person is in the

• A. Arms.
• B. Upper torso.
• C. Head.
• D. Feet.

Correct answer: B

Rationale: The correct answer is 'Upper torso.' In elderly individuals, the center of gravity tends to shift upwards towards the upper torso due to various factors such as changes in posture and muscle strength. Understanding this is crucial for safe ambulation as it helps in maintaining balance and stability. Choices A, 'Arms,' C, 'Head,' and D, 'Feet,' are incorrect. The center of gravity is not typically located in the arms, head, or feet. It is higher up in the body, specifically in the upper torso. Knowing the correct location of the center of gravity is essential for assisting elderly clients in ambulation effectively and preventing falls.

5. The nurse is caring for a client with a central venous catheter. What is the most important action for the nurse to take to prevent infection?

• A. Change the catheter dressing every 72 hours.
• B. Flush the catheter with heparin solution daily.
• C. Ensure the catheter is clamped when not in use.
• D. Maintain sterile technique when handling the catheter.

Correct answer: D

Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. Changing the catheter dressing every 72 hours, while important for overall catheter care, does not directly address infection prevention. Flushing the catheter with heparin solution daily is essential for maintaining patency but does not primarily prevent infections. Ensuring the catheter is clamped when not in use is important for preventing air embolism but is not the most critical action to prevent infection. The most effective way to prevent infections is by strictly adhering to sterile techniques during catheter handling, which minimizes the risk of introducing pathogens into the catheter site.
