Nursing Elites

1. A client with myasthenia gravis (MG) is receiving immunosuppressive therapy. Review of recent laboratory test results shows that the client’s serum magnesium level has decreased below the normal range. In addition to contacting the healthcare provider, what nursing action is most important?

• A. Check the visual difficulties
• B. Note the most recent hemoglobin level
• C. Assess for hand and joint pain
• D. Observe rhythm on telemetry monitor

Correct answer: D

Rationale: The correct answer is to observe the rhythm on the telemetry monitor. Decreased magnesium levels can lead to cardiac issues, such as arrhythmias. Monitoring the heart rhythm is crucial in this situation. Checking visual difficulties (choice A) is not directly related to the potential cardiac effects of low magnesium levels. Noting the hemoglobin level (choice B) and assessing for hand and joint pain (choice C) are not the priority when dealing with low magnesium levels and possible cardiac complications.

2. The nurse is admitting a client from the post-anesthesia unit to the postoperative surgical care unit. Which intervention should the nurse implement first?

• A. Advance to clear liquids as tolerated
• B. Straight catheterization if unable to void
• C. Administer Cefazolin 1 gram IVPQ q6 hours
• D. Obtain a complete blood cell count (CBC) in the morning

Correct answer: B

Rationale: The correct answer is to perform straight catheterization if the client is unable to void. This action is essential to prevent urinary retention and its potential complications following anesthesia. Option A, advancing to clear liquids, is not the priority upon admission as the focus should be on urinary function first. Option C involves administering an antibiotic, which is important but not the immediate priority. Option D, obtaining a CBC, can be done later and is not as crucial as ensuring proper urinary function postoperatively.

3. When admitting a client diagnosed with active tuberculosis to isolation, which infection control measures should the nurse implement?

• A. Negative pressure environment
• B. Contact precautions
• C. Droplet precautions
• D. Protective environment

Correct answer: A

Rationale: The correct answer is A: Negative pressure environment. Tuberculosis is transmitted through airborne particles, so a negative pressure room is essential to prevent the spread of the bacteria. Choice B, contact precautions, are used for infections spread by direct or indirect contact, not for tuberculosis. Choice C, droplet precautions, are for infections transmitted through respiratory droplets, not airborne particles like tuberculosis. Choice D, protective environment, is used for protecting immunocompromised patients from outside pathogens, not for preventing the spread of tuberculosis.

4. A 17-year-old adolescent is brought to the emergency department by both parents because the adolescent has been coughing and running a fever with flu-like symptoms for the past 24 hours. Which intervention should the nurse implement first?

• A. Obtain a chest X-ray per protocol.
• B. Place a mask on the client’s face.
• C. Assess the client’s temperature.
• D. Determine the client’s blood pressure

Correct answer: B

Rationale: The correct intervention for the nurse to implement first is to place a mask on the client's face. This is crucial to prevent the potential spread of infectious agents to others in the emergency department, considering the presenting symptoms of coughing and fever. Placing a mask helps in containing respiratory secretions and reducing the risk of airborne transmission. Assessing the client’s temperature or blood pressure can be done after ensuring infection control measures. Obtaining a chest X-ray would be a secondary intervention once immediate infection control is addressed.

5. A client is admitted to the hospital with a serum sodium level of 128 mEq/L, distended neck veins, and lung crackles. What intervention should the nurse implement?

• A. Increase the intake of salty foods
• B. Administer NaCl supplements
• C. Restrict oral fluid intake
• D. Hold the client's loop diuretic

Correct answer: C

Rationale: In the scenario described, the client presents with signs of fluid overload and hyponatremia. Restricting oral fluid intake is the appropriate intervention to manage fluid overload and correct hyponatremia. Increasing the intake of salty foods (Choice A) and administering NaCl supplements (Choice B) would exacerbate the sodium imbalance. Holding the client's loop diuretic (Choice D) is not directly related to addressing the fluid overload and hyponatremia.
