Nursing Elites

1. 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.

2. 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.

3. While instructing a male client's wife in the performance of passive range-of-motion exercises to his contracted shoulder, the nurse observes that she is holding his arm above and below the elbow. What nursing action should the nurse implement?

• A. Acknowledge that she is supporting the arm correctly.
• B. Encourage her to keep the joint uncovered to maintain warmth.
• C. Reinforce the need to grip directly under the joint for better support.
• D. Instruct her to grip directly over the joint for better motion.

Correct answer: A

Rationale: The wife is correctly performing the passive range-of-motion exercises by holding the arm above and below the elbow. The nurse should acknowledge this correct technique (A). It is essential to keep the joint uncovered (B) during exercises, while ensuring the rest of the body remains covered for warmth and privacy. Choices (C) and (D) do not provide optimal support to the joint for effective movement.

4. During the assessment, a client receiving a continuous infusion of heparin for deep vein thrombosis (DVT) is found to have a nosebleed. Which finding requires immediate action?

• A. The client's activated partial thromboplastin time (aPTT) is 70 seconds.
• B. The client has developed a nosebleed.
• C. The client's blood pressure is 150/90 mm Hg.
• D. The client reports feeling lightheaded.

Correct answer: B

Rationale: A nosebleed (B) in a client receiving heparin is a sign of heparin toxicity and requires immediate action. It indicates that the client is at risk of excessive bleeding. While a prolonged aPTT of 70 seconds (A) is worth monitoring, active bleeding takes precedence. Elevated blood pressure (C) and lightheadedness (D) are potential side effects of heparin but are not as urgently concerning as active bleeding.

5. What action should be taken when adding sterile liquids to a sterile field?

• A. Use an expired sterile liquid if the bottle is sealed and unopened.
• B. Consider the sterile field contaminated if it becomes wet during the procedure.
• C. Remove the container cap and place it with the inside facing up on the sterile field.
• D. Hold the container low and pour the solution into a receptacle at the front of the sterile field.

Correct answer: B

Rationale: If a sterile field becomes wet or damp during a procedure, it is considered contaminated as moisture can allow organisms to wick from the surface and compromise the sterility of the field. It is essential to maintain the integrity of the sterile field to prevent infections and ensure patient safety.
