Nursing Elites

1. The healthcare provider is caring for a client who has just been diagnosed with myasthenia gravis. Which symptom should the healthcare provider expect to observe?

• A. Muscle weakness
• B. Joint pain
• C. Vision changes
• D. Skin rash

Correct answer: A

Rationale: Muscle weakness is a hallmark symptom of myasthenia gravis, a neuromuscular disorder characterized by impaired neuromuscular transmission. This results in muscle weakness, particularly in skeletal muscles that control eye movements, facial expressions, chewing, swallowing, and speaking. Joint pain (Choice B) is not a typical symptom of myasthenia gravis and is more commonly associated with conditions like arthritis. Vision changes (Choice C) may occur in conditions affecting the eyes, but they are not specific to myasthenia gravis. Skin rash (Choice D) is also not a typical manifestation of myasthenia gravis. Therefore, the correct answer is muscle weakness (Choice A).

2. When admitting a client with an abdominal wound, which precaution should be taken?

• A. Contact precautions
• B. Droplet precautions
• C. Airborne precautions
• D. Standard precautions

Correct answer: A

Rationale: When admitting a client with an abdominal wound, contact precautions should be implemented. Contact precautions are used to prevent the spread of infections that are spread by direct or indirect contact. In the case of abdominal wounds, bacteria and pathogens can easily be transmitted through contact with the wound or wound drainage. Droplet precautions are used for infections transmitted through respiratory droplets, such as influenza. Airborne precautions are used for infections spread through the air, like tuberculosis. Standard precautions are used for all clients to prevent the spread of infections and should be followed in addition to specific precautions based on the type of infection.

3. When preparing to apply dressing to a stage 2 pressure injury, which type of dressing should the nurse use?

• A. Hydrocolloid
• B. Gauze
• C. Transparent film
• D. Alginate

Correct answer: A

Rationale: The correct answer is A: Hydrocolloid. Hydrocolloid dressings are recommended for stage 2 pressure injuries as they help maintain a moist wound environment, which supports the healing process. Gauze (choice B) is not ideal for stage 2 pressure injuries as it can stick to the wound bed and disrupt the healing process. Transparent film dressings (choice C) are more suitable for superficial wounds or as a secondary dressing. Alginate dressings (choice D) are typically used for wounds with heavy exudate, which is not typically seen in stage 2 pressure injuries.

4. 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.

5. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?

• A. Blood glucose of 350 mg/dL
• B. Serum bicarbonate of 18 mEq/L
• C. Arterial pH of 7.20
• D. Serum potassium of 5.5 mEq/L

Correct answer: C

Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.
