Nursing Elites

1. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.

2. A healthcare professional is caring for a client who has a prescription for a stool specimen to be sent to the laboratory to be tested for ova and parasites. Which of the following instructions regarding specimen collection should the healthcare professional provide to the assistive personnel?

• A. Collect at least 2 inches of formed stool.
• B. Wear sterile gloves while obtaining the specimen.
• C. Use a culturette for specimen collection.
• D. Record the date and time the stool was collected.

Correct answer: A

Rationale: To ensure accurate testing, a minimum amount of stool is required for specimen collection, typically at least 2 inches of formed stool. This amount provides an adequate sample for testing. Wearing sterile gloves is important for infection control but is not specifically required for stool specimen collection. Using a culturette is not typically necessary for collecting stool specimens. Recording the date and time the stool was collected is essential to ensure timely processing but does not directly impact the collection of the specimen itself.

3. A client has C-diff infection. Which of the following actions should the nurse take?

• A. Give the client chlorhexidine gluconate for hand hygiene.
• B. Remove the protective gown first when exiting the client's room.
• C. Use alcohol-based hand rub when caring for the client.
• D. Initiate contact precautions when providing client care.

Correct answer: D

Rationale: The correct answer is to initiate contact precautions when providing client care. C-diff (Clostridium difficile) is highly contagious, and contact precautions are necessary to prevent its spread. Giving the client chlorhexidine gluconate for hand hygiene (Choice A) is not specific to managing C-diff. Removing the protective gown first when exiting the client's room (Choice B) may increase the risk of contaminating oneself and the environment. Using alcohol-based hand rub when caring for the client (Choice C) is not sufficient to prevent the transmission of C-diff, as soap and water are more effective against this particular pathogen.

4. A nurse discovers a small paper fire in a trash can in a client’s bathroom. The client has been taken to safety and the alarm has been activated. Which of the following actions should the nurse take?

• A. Open the windows in the client’s room to allow smoke to escape.
• B. Obtain a class C fire extinguisher to extinguish the fire.
• C. Remove all electrical equipment from the client’s room.
• D. Place wet towels along the base of the door to the client’s room.

Correct answer: B

Rationale: The correct answer is B: Obtain a class C fire extinguisher to extinguish the fire. Using a class C fire extinguisher is appropriate for electrical fires, which can include fires involving electrical equipment or appliances. In this scenario, a paper fire in a trash can in the client's bathroom could potentially involve electrical components, making a class C fire extinguisher the most suitable choice. Option A, opening the windows, may help with ventilation but does not address the fire directly. Option C, removing electrical equipment, is a precautionary measure but does not address the immediate fire hazard. Option D, placing wet towels along the base of the door, is a strategy to prevent smoke from entering the room but does not extinguish the fire.

5. A client has been on bed rest for several weeks. Which finding should the nurse identify as the priority during assessment?

• A. Musculoskeletal weakness
• B. Loss of appetite
• C. Increased heart rate during physical activity
• D. Left lower extremity tenderness

Correct answer: D

Rationale: The nurse should prioritize assessing left lower extremity tenderness as it could indicate deep vein thrombosis, a serious condition that requires immediate attention. Musculoskeletal weakness, loss of appetite, and increased heart rate during physical activity are important but not as critical as a potential thrombotic event that could lead to life-threatening complications. Deep vein thrombosis is a common risk for individuals on prolonged bed rest due to reduced mobility and blood stasis.
