Nursing Elites

1. A client with a history of myocardial infarction (MI) is admitted with chest pain. Which laboratory test should the nurse expect to be ordered to determine if the client is experiencing another MI?

• A. Troponin
• B. Myoglobin
• C. CK-MB
• D. C-reactive protein

Correct answer: A

Rationale: Troponin is the most specific and sensitive laboratory test for detecting myocardial infarction (MI). It is released when there is damage to the heart muscle, making it a valuable marker for diagnosing another MI. Myoglobin and CK-MB can also be elevated in MI, but troponin is preferred due to its higher specificity. C-reactive protein is a marker of inflammation and not specific to MI.

2. Twenty minutes after beginning a heat application, the client states that the heating pad no longer feels warm enough. What is the best response by the nurse?

• A. That means you have derived the maximum benefit, and the heat can be removed.
• B. Your blood vessels are becoming dilated and removing the heat from the site.
• C. We will increase the temperature by 5 degrees when the pad no longer feels warm.
• D. The body's receptors adapt over time as they are exposed to heat.

Correct answer: D

Rationale: Choice (D) describes thermal adaptation, which occurs 20 to 30 minutes after heat application. The body's receptors adjust to the constant heat exposure, leading to a decreased sensation of warmth. Choices (A) and (B) provide inaccurate information regarding the situation, while choice (C) is not physiologically sound and could potentially harm the client by increasing the temperature unnecessarily.

3. A client is scheduled for a colonoscopy. What instruction should the nurse provide to prepare the client for the procedure?

• A. Drink clear liquids for 24 hours before the procedure
• B. Take a laxative the morning of the procedure
• C. Eat a light meal before the procedure
• D. Avoid drinking fluids for 4 hours before the procedure

Correct answer: A

Rationale: The correct instruction for preparing a client for a colonoscopy is to drink clear liquids for 24 hours before the procedure. This step helps to ensure the bowel is adequately cleared for the colonoscopy, allowing for better visualization and examination of the colon.

4. The client has received a new diagnosis of heart failure, and the nurse is providing dietary management education. Which instruction should the nurse include?

• A. Increase intake of foods high in potassium.
• B. Avoid foods high in sodium.
• C. Limit fluid intake to 1.5 liters per day.
• D. Increase intake of foods high in vitamin K.

Correct answer: B

Rationale: Avoiding foods high in sodium (choice B) is essential for clients with heart failure to prevent fluid retention and decrease the strain on the heart. High sodium intake can lead to fluid buildup, exacerbating heart failure symptoms. Increasing potassium intake (choice A) can be harmful in heart failure if not monitored closely as it can affect heart rhythm. Limiting fluid intake (choice C) may be necessary in some cases, but the specific amount should be individualized based on the client's condition. Increasing vitamin K intake (choice D) is not a primary concern in heart failure management and is more relevant for clients on anticoagulants to manage blood clotting.

5. What instruction should be provided for a UAP caring for a client with MRSA who has an order for contact precautions?

• A. Do not allow visitors until precautions are discontinued
• B. Wear sterile gloves when handling the client’s body fluids
• C. Have the client wear a mask whenever someone enters the room
• D. Don a gown and gloves when entering the room

Correct answer: D

Rationale: The correct instruction for a UAP caring for a client with MRSA under contact precautions is to don a gown and gloves when entering the client's room. This precaution is essential to prevent the spread of MRSA and protect both the client and the healthcare worker from potential infection. Choice A is incorrect because visitors should not be restricted solely based on contact precautions. Choice B is incorrect as wearing sterile gloves is not necessary, standard precautions with regular gloves are sufficient. Choice C is incorrect because the client wearing a mask is not a standard practice for contact precautions; it is the healthcare worker who should take preventive measures.
