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 client has Clostridium difficile and is in contact isolation. Which of the following actions should the nurse take?

• A. Wear gloves when changing the client's gown.
• B. Use hand sanitizer after contact with the client.
• C. Wear a mask when entering the client's room.
• D. Clean the room with a disinfectant spray.

Correct answer: A

Rationale: The correct action for the nurse to take when caring for a client with Clostridium difficile in contact isolation is to wear gloves when changing the client's gown. Clostridium difficile is highly transmissible, and wearing gloves helps prevent the spread of the infection. Using hand sanitizer after contact with the client (Choice B) is not enough to prevent the transmission of C. difficile, as the spores can persist and spread. Wearing a mask when entering the client's room (Choice C) is not necessary for C. difficile transmission, which primarily occurs through contact with contaminated surfaces. Cleaning the room with a disinfectant spray (Choice D) is important, but wearing gloves during direct care is the priority to prevent the nurse from acquiring and spreading the infection.

3. A nurse observes smoke coming from under the door of the staff lounge. Which of the following actions is the nurse's priority?

• A. Extinguish the fire.
• B. Activate the fire alarm.
• C. Move clients who are nearby.
• D. Close all open doors on the unit.

Correct answer: B

Rationale: In a fire emergency, the nurse's priority is to activate the fire alarm. This action alerts others to the emergency, initiates the evacuation process, and ensures everyone's safety. Extinguishing the fire can be dangerous and should be left to trained personnel. Moving clients who are nearby might delay the activation of the alarm and can put the nurse and clients at risk. Closing all open doors on the unit is important to contain the fire but should not take precedence over alerting others through the fire alarm system.

4. A client with congestive heart failure (CHF) is receiving furosemide (Lasix). Which laboratory value should the LPN monitor closely while the client is taking this medication?

• A. Sodium
• B. Potassium
• C. Calcium
• D. Magnesium

Correct answer: B

Rationale: The LPN should monitor potassium levels closely while the client is taking furosemide (Lasix) due to the medication's potential to cause hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through increased urine output. Hypokalemia can result in serious complications such as cardiac dysrhythmias. Monitoring sodium levels (choice A) is important but not as critical as monitoring potassium in this context. Calcium (choice C) and magnesium (choice D) levels are not typically affected by furosemide and are not the priority for monitoring in this scenario.

5. A nurse receives a prescription for an antibiotic for a client with cellulitis. The nurse checks the client’s medical record, discovers the client's allergy to the antibiotic, and calls the provider for a different prescription. Which of the following critical thinking attitudes did the nurse demonstrate?

• A. Fairness
• B. Responsibility
• C. Risk-taking
• D. Creativity

Correct answer: B

Rationale: The nurse demonstrated responsibility by recognizing the potential harm of administering an antibiotic the client is allergic to and taking the necessary steps to ensure the client's safety. Choice A, 'Fairness,' is not applicable in this scenario as it does not involve treating individuals equitably. Choice C, 'Risk-taking,' is incorrect as the nurse's actions aimed to minimize risks rather than taking them. Choice D, 'Creativity,' is not the best fit as the nurse's actions focused on following established protocols and ensuring patient safety rather than thinking innovatively.
