Nursing Elites

1. A client with a diagnosis of coronary artery disease is receiving atorvastatin (Lipitor). Which laboratory test should the nurse monitor to evaluate the effectiveness of this medication?

• A. Complete blood count (CBC)
• B. Serum potassium level
• C. Liver function tests (LFTs)
• D. Serum cholesterol level

Correct answer: C

Rationale: To evaluate the effectiveness of atorvastatin (Lipitor), the nurse should monitor liver function tests (LFTs) (C) because this medication can impact liver function. Complete blood count (CBC) (A), serum potassium level (B), and serum cholesterol level (D) are not directly indicative of the medication's effectiveness in managing coronary artery disease.

2. When taking a client's blood pressure, the healthcare professional is unable to distinguish the point at which the first sound was heard. What is the best action for the healthcare professional to take?

• A. Deflate the cuff completely and immediately reattempt the reading.
• B. Reinflate the cuff completely and leave it inflated for 90 to 110 seconds before taking the second reading.
• C. Deflate the cuff to zero and wait 30 to 60 seconds before reattempting the reading.
• D. Document the exact level visualized on the sphygmomanometer where the first fluctuation was seen.

Correct answer: C

Rationale: The correct action when unable to distinguish the point of the first sound during blood pressure measurement is to deflate the cuff to zero and wait 30 to 60 seconds before reattempting the reading. This allows blood flow to return to the extremity, ensuring a more accurate reading the second time. It is important to ensure that the cuff is fully deflated and the appropriate wait time is given to obtain an accurate blood pressure measurement.

3. 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.

4. What is the most important instruction for the nurse to provide to a 65-year-old client who attends an adult daycare program, is wheelchair-mobile, and has redness in the sacral area?

• A. Take a vitamin supplement tablet once a day.
• B. Change positions in the chair at least every hour.
• C. Increase daily intake of water or other oral fluids.
• D. Purchase a newer model wheelchair.

Correct answer: B

Rationale: For a client with redness in the sacral area, the most critical instruction is to change positions in the chair at least every hour. This is crucial to prevent pressure ulcers, which can develop due to prolonged pressure on the skin and underlying tissues. Regular position changes help relieve pressure on vulnerable areas, promoting circulation and reducing the risk of skin breakdown and pressure ulcer formation.

5. The client with chronic obstructive pulmonary disease (COPD) is being taught pursed-lip breathing by the nurse. What is the purpose of this technique?

• A. To promote oxygenation by removing secretions.
• B. To reduce the amount of air trapped in the lungs.
• C. To increase the amount of carbon dioxide exhaled.
• D. To slow the respiratory rate and improve air exchange.

Correct answer: C

Rationale: Pursed-lip breathing is used to increase the amount of carbon dioxide exhaled (C) in clients with chronic obstructive pulmonary disease (COPD). By doing so, it helps prevent air trapping and enhances gas exchange, ultimately improving respiratory efficiency. While removing secretions (A) and reducing air trapping (B) can be associated benefits to some extent, the primary goal of pursed-lip breathing is to optimize carbon dioxide elimination and enhance breathing mechanics. Slowing the respiratory rate (D) is not the primary purpose of pursed-lip breathing.
